Evaluation of the Biological Effects of Radiations on Pulmonary
functions of NMA Employees in the Black Sand Project at Rashid
and Abou-Khashaba Sites Year 2012
Nesriene Mohamad El Margoushy
Medical and Radiation Research Department, Nuclear Materials Authority
Background: Almost all workers in the Black Sand Project at Rashid and Abou-Khashaba sites
of NMA (Nuclear Materials Authority) are obligatorily exposed to ionizing radiations during
their routine work. The most apparent harmful effects in Rasheed employees were reflected
easily on pulmonary function tests which may occur due to increase registered dust radio
activities than the accepted level for air concentration.
Objectives: This study was done mainly to evaluate the biological effects of ionizing radiations
on lung and pulmonary functions of workers in the Black Sand Project at Rashid and Abou-
Khashaba sites of NMA in the year 2012 and to start follow up of these workers
Measurements: This research was done on 30 male workers aging 25 - 56 years to measure
pulmonary function tests. Certain radiological measurements were also performed to assess the
levels of exposure to radiations
Results: Out of the 30 members; regarding the radiological measurements all levels measured
were within the reference range accepted internationally, except radioactive dust levels were
elevated mildly above the reference range accepted internationally this results in deterioration of
pulmonary function of some workers.
Conclusions: Generally, workers of the Black Sand Project at Rashid and Abou-Khashaba sites
were receiving a good radiological protection protocol. Radioactive dust levels were elevated
mildly above the reference range accepted internationally this result in pulmonary function
disorders in some workers.

A Comparative Study Between Whole Body Magnetic Resonance
Imaging and Bone Scintgraphy In Detection of Bone Metastases In
Patients With Known Breast or Lung Cancer
Wafaa Raafat Ali Abdel Hamid;
Department of Radiodiagnosis, Ain Shams University
Purpose: The aim of this work is to compare the ability of whole body MRI including
diffusion study with that of 99m Tc-Methylene Diphosphonate Scintigraphy to detected
skeletal metastases in patients with breast and lung cancer.
Patients and methods: 60 patients comprising 38 females and 22 males ranging in age from
30 to 60 years with a mean age of 48.1 years (mean age 47.3 years for females and 49 years
for males) were enrolled in the study. 29 females are histopathologically proven cases of
breast malignancy, 9 females and the 22 males are histopathologically proven cases of lung
The patients were referred from Oncological departments to perform the whole body MR
study and bone scan at Ain Shams University hospitals MRI units and a private center during
the time interval from December 2008 till December 2012.
All patients were subjected to both whole body MRI and bone scintigraphy. The whole body
MRI was mainly obtained using 4 contiguous coronal stations for body coverage using the
body coil and 2 contiguous sagittal stations for the spine using T1W FSE and STIR
sequences. 48 out of 60 patients toke IV contrast and post contrast T1W imagaes with fat
suppression were taken. The MRI examinations were performed using a superconducting 1.5
Tesla magnet (Achieva: Philips Medical Systems).
Standard skeletal Scintigraphy was performed using a planar one phase technique (delayed
phase). The examination was done 2-3 hours after IV injection of technicium 99m labeled
Methylene Diphosphonate with a maximum dose of 20 mCi.
Results: 42 patients out of 60 were positive for metastases based on histopathological
verification or follow up. On MRI, 39 patients had metastases, 3 were false negative, 12 were
true negative and 6 were false positive. On bone scan, 35 were true positive, 7 were false
negative, 4 were false positive and 14 were true negative.
Based on lesion detection, on comparing bone scan to WB-MRI with and without diffusion,
bone scan had an overall sensitivity of 85.6%, specificity 67.5 %, PPV 61.7% and NPV
66.3%, while WB-MRI had statistical values of 73.4%, 68.8%, 78.1% and 62.6%
On adding DWI, values raised to 88.9%, 82.9%, 93% and 69% respectively.
Quantitative analysis of DWI was also included in this study revealing an overlap between the
Low ADC values of red marrow and metastasis at the range of 0.61 to 0.69 x10-3 mm2/sec and
then between metastasis and other benign pathological marrow entities at the range of 0.9 to
1.03 x 10-3 mm2/sec.
WB-MRI also detected 64 soft tissue metastatic lesions which became 71 lesions on adding
DWI with a distribution of hepatic, pulmonary, brain, adrenal, lymph nodes, pleural,
leptomeningeal and renal lesions.
Conclusion: we don't think that WB-MRI should replace bone scan in the quest for skeletal
metastases. However, we believe that WB-MRI should be the modality of choice when both

Introduction: Pelvic floor weakening is a major health problem in older women, with an 11.1%
lifetime risk of women over 50 years old to undergo surgery for pelvic organ prolapse and urinary
incontinence. Clinical examination is the main method of diagnosis, yet imaging is essential especially
in patients with multicompartment defects. Pelvic Magnetic Resonance (MR) Imaging is expected to
play a role in the preoperative planning for complex cases due to its high soft tissue resolution, which
will help perform site-specific repair and so avoid recurrence.
Aim of the work: The aim of this work is to evaluate the role of Magnetic Resonance Imaging as a
non invasive method in the assessment of female pelvic floor dysfunction.
Methods: The studied group included 40 female patients complaining of pelvic organ prolapse and /
or stress urinary incontinence or fecal incontinence. All patients were subjected to full history taking,
clinical examination and Dynamic Magnetic resonance Imaging using 1.5 Tesla Philips MR Scanner.
Results: Good concordance was found between Dynamic MRI and clinical examination in all three
compartments. The concordance was 82.5% in the anterior compartment, 80% in the posterior
compartment, 85% in enteroceles and 65.0% in the middle compartment.
Conclusion: Dynamic MRI is a promising method that can be used as an imaging tool in the
preoperative planning of pelvic organ prolapse.

Radiodiagnosis department, Faculty of Medicine, Ain Shams University
Purpose: to assess the role of CT colonography (virtual colonoscopy) as a non-invasive imaging
technique in detection and diagnosis of colorectal neoplasia using conventional colonoscopy and/or
operative findings as a reference standard, as well as highlighting its advantages and possible pitfalls.
Methods: sixty patients were examined by CT after standard bowel preparation, rectal insufflation and IV
contrast injection. Imaging was performed in both supine and prone positions. Evaluation consisted of
review of the transverse CT images, sagittal and coronal reformations and 3D endoluminal lmages. CT
colonographic findings were correlated with standard conventional colonoscopic and/or operative
Results: Virtual colonoscopy correctly identified all 6 carcinomas (100%), 12 out of the 13 polyps that
measured 10mm or more (92.3%), 19 of the 23 polyps that measured 6 - 9 mm (82.6%) and 28 out of 48
polyps that measured 5mm or less (58.3%). There were 11 false positive findings of polyps by virtual
colonoscopy and no false positive findings of cancer. Virtual colonoscopy also detected 35 incidental
extracolonic findings in 25 patients while non were detected by conventional colonoscopy. 17 of the 24
patients who had no lesions during conventional colonoscopy were considered free of lesions by CT
colonography yielding a per-patient specificity of 70.8%
Conclusion: CT colonography has high sensitivity for the detection of clinically important polyps and
cancer as well as multiple advantages over conventional colonoscopy in imaging of colorectal neoplasms.

Aim of the Work: The aim of this study is to evaluate and compare the epi-on versus the epi-off techniques
of corneal collagen cross linking as regards their safety and efficacy for treatment of mild to moderate degree
Design: Prospective, non randomized study.
Patients and Methods: Thirty eyes in 15 patients (9 males and 6 females) with bilateral mild to moderate
degree keratoconus were included in this study. Their mean age ± SD was 26.2 ± 3.9 years. Diagnosis of
keratoconus was based on clinical evaluation as well as pentacam examination. All patients were subjected to
corneal collagen cross linking. According to the technique used, eyes were classified into 2 groups:
Group I: Included 15 eyes in 15 patients, where cross linking was performed after removal of the corneal
Group II: included the other 15 eyes of the same patients, where cross linking was performed with intact
epithelium (Epi-on). Comparison between the two groups as regards visual outcome, keratometric readings,
least corneal thickness, refraction outcome and corneal haze was done.
Results: No intra operative complications were reported in our study. Re-epithelialization in eyes of group I
was reported within a week except three eyes were re- epithelialization was reported after 10,14and 21 days.
There was a statistically significance improvement in best corrected visual acuity in both groups (0.36 before
versus 0.60 six months after surgery) but the difference between both groups was not significant.
As regards refraction, there was reduction in spherical error 6 months after surgery in both groups (-6.14D
before,-5.22D 6 months after surgery) as well as cylindrical error (4.87D before 3.79 D 6 month after
Differences between both groups were statistically not significant.
There was increase in the least corneal thickness after surgery (448.6 microns before surgery versus 451.9
microns 6 months after surgery) but statistically the difference was not significant (P=0.75) and the difference
between both groups was also not significant.
Changes in keratometric readings were statistically not significant, and the difference between both groups
was also not significant.
Corneal haze was observed one month post operatively in four eyes in group one versus 3 eyes in group II.
Persistent haze at the end of follow up was reported in three eyes in group I versus two eyes in group II.
The incidence of haze as well as its density was higher in group I than group II with statistical significant
Conclusion: Both epi-on and epi-off techniques of corneal collagen cross linking are safe and effective in
stabilization or even improvement of mild to moderate degree keratoconus as regards best corrected visual

Immunomodulatory Changes Induced By High Doses Of Dextromethorphan
In Male Rats
Hanan Mostafa Rabei
Narcotic Department, the National Centre for Social and Criminological Research, Cairo-Egypt
Dextromethorphan (DXM) is a synthetic opioid analogue, similar to codeine that has antitussive
effect but no opiate-like analgesic activity. It is widely used as an over-the-counter cough suppressant
available in various cough and cold preparations; it is one of the often overlooked types of substance
abuse by adolescents and young adults in the United States and around the world. So, the present study
aims to investigate the side effects of the DXM abuse (sub-chronic and lethal doses) on the immune
functions in rats.
Material and Methods:
The rats were divided into three equal groups, the first one served as control, and the second and
third were treated. Treated groups received oral doses of DXM which increasing per 10 days (double
dose) for a month.
We examined the sub-chronic and lethal effects of DXM administration on the cellular immune
responses in rats. T cell stimulator, Phytohemagglutinin showed a significant suppress on lymphocytes of
peripheral blood proliferation and a highly significant decrease on phagocytic and killing of S. aureus by
PMN and macrophage cells. Moreover, it induced a significant decrease in serum IL-6, and IFN- levels,
but, it exhibited a highly significant increase in serum IL-10 level throughout the period of experiment. In
addition, it induced also a significant decrease in the production of cortisol during the experimental time
except the last period of treatment in the 3rd group, where, serum cortisol level gradually return to normal

development of and mortality from coronary heart disease (CHD), increasing the risk by 2 to 4 times.
According to WHO data, more than 75% of patients with DM die due to vascular accidents. This study
investigated the effects of some plants used in Saudi Arabia and some other Arab countries as antidiabetic
agents and explores its metabolic effects.
Material and Methods: One hundred fifty adult male Albino Rats were divided into six experimental
groups each consist of twenty five rats. The first group was considered as a control group. The rest of
groups were affected by induction of experimental diabetes by subcutaneous injection of Alloxan. The
second group consisted of diabetic rats without any treatment. The third group was treated by the aqueous
extract of mixture contains Foenugreek, Nigella sativa and Termis seeds. The fourth group was treated with
the aqueous extract of Nigella sativa seeds (100 mg / kg of body weight), while the fifth group was treated
with the aqueous extract of Foenugreek seeds (100 mg / kg of body weight). The sixth one was treated with
the aqueous extract of Termis seeds (100 mg/kg body weight). After four weeks of treatment, different
biochemical parameters were performed including estimation of blood sugar level and serum insulin level.
Pancreatic and liver samples were obtained and processed for microscopic and quantitative evaluation after
staining the prepared sections with both Heamatoxylin and Eosin as well as special stain for demonstration
of the different pancreatic cells in the Islet of the Langerhans.
Results: The usage of the mixture or each plant alone corrected the glucose level and insulin level.
Microscopically there was definite decrease in the number and diameter of beta pancreatic cells in the
diabetic group while the other pancreatic cells were not affected (alpha and delta cells). The use of
medicinal plants in the different groups of this study greatly improved such cellular changes and the level of
blood sugar level was corrected. Also, improve dyslipidemia present in diabetic rats. The results showed
that the activity of the mixture was better when compared with Nigella, Foenugreek or Termis seeds alone.
Conclusions: The water extract of the mixture is the most powerful in amelioration hyperglycemia and
most of all damage effects of Alloxan on hematological parameters and lipid profile. Also, it can control
most of the metabolic risk factors of CAD in diabetic rats. So it is advised to use the plant mixture as an
antidiabetic agent rather than the use of each plant separately. Repeating such study with the use of variable
doses may be helpful in better evaluation for the required dose.

Background: There is high prevalence of combined peripheral and coronary artery disease
(CAD) related to atherosclerosis with associated increase in morbidity and mortality .
Objectives:The aim of our study was to find an association between ankle brachial index
(ABI) and cardiac function in elderly patients with CAD using ejection fraction (EF).
Method: A Case control study. The case group included 100 elderly patients who had
peripheral artery disease ( PAD) divided into 2 groups according to age ( 60- 70 and > 70
years). The control group included 100 elderly subjects who didn't have PAD which were
divided also into 2 groups according to age . Both groups have CAD and underwent coronary
angiography (CA) showing significant CAD lesions. Echocardiography were done to all
patients showing cardiac function. Results: EF was lowest in cases > 70 years (46.84 ± 9.82)
and was highest in controls > 70 years (53.02 ± 5.53) which is statistically significant (P-
Value 0.009). Also EF is correlated with ABI.
Conclusion: There is a significant positive relationship between ABI and EF.

Background: The present study aimed to evaluate the expression of Matrix Metalloproteinase-1 (MMP1)
in HepatoCellular Carcinoma (HCC) by using the Immunohistochemical technique, which allows us to
integrate the biological aspects of this enzymatic expression in the morphological context of HCCs.
Material and Methods: The study was performed on 70 subjects from out and in patients of Tropical
medicine Department, Thiodor Billhars Institute during the period from January 2011 until June 2012. The
present study included 60 patients with chronic hepatitis C who had undergone liver biopsy. They consisted
of 42 men and 28 women with ages ranging from 36 to 66 years. The diagnosis of chronic hepatitis C was
made on the basis of positivity for anti-HCV (by the second generation ELISA), and confirmed by HCV-
RNA reverse transcription polymerase chain reaction (RT-PCR). Patients were divided into four groups:
Group I: included 10 normal persons with no history of liver disease with normal liver enzymes and free
ultrasonographic finding as normal control. It included 6 males, 4 females, with ages ranging from 34 to 48
years. Group II: included 20 HCV infected patients without cirrhotic changes. It included 11 males, 9
females, with ages ranging from 39 to 53 years. Group III: included 20 HCV infected patients with liver
cirrhosis, 12 males, 8 females, with ages ranging from 48-63 years. Group IV: included 20 HCV infected
patients with HCC, 16 males, 4 females, with ages ranging from 53-64 years.
Results: Blood Picture, (Hb, WBCs, RBCs, Plts, PC and ESR). Liver Function Test (ALT, AST, ALB,
GGT, ALP, T. BIL and D. BIL). Matrix Metalloprotenase 1(MMP1) Measurements: Serum MMP1.
Histopathological investigation Including histopathological changes in the liver tissue.
Conclusion: our results suggest that MMP-1 is overexpressed in a large proportion of patients with HCC
and the high expression level of protein correlated with the disease progression and poor clinical outcome in
HCC. Furthermore, MMP-1 high expression proved to be a risk factor for tumor recurrence and
independent molecular marker of prognosis in HCC and may become a novel target in the strategies for the
prediction of tumor progression and prognosis of this disease.

Introduction: intracranial aneurysms are pathological enlargement of the brain arteries that are
most commonly located in the circle of Willis. Intracranial aneurysms are relatively common with a
prevalence of approximately 4%. The real danger of aneurysms is subarachnoid hemorrhage. 3D
digital subtraction angiography has become a critical imaging tool in neuroradiology allowing for
the visualization of detailed cerebral vasculature prior to any intervention.
Aim of the work: The aim of this work is to evaluate the diagnostic performance of 3D
conventional angiography in the evaluation of intracranial aneurysms compared with the
conventional cerebral angiography.
Methods: The studied group included 20 patients (5 men and 15 women) with subarachnoid
hemorrhage or known to have cerebral aneurysms. All patients were subjected to conventional
cerebral angiography and 3D cerebral angiography, using C-arm (Toshiba) rotational technique.

Diagnostic Validity of Serum and Peritoneal TNF-alpha, high sensitivity
CRP and Plasma Cell-Free Nuclear DNA (ccf nDNA) as Biomarkers of
Pelvic Endometriosis- A Case Control Study
Ahmed F Koura, MSc*, Mohamed A Yehia, Waleed H ElTantawy, Adel S Salah El Din, Dina
* Departments of Obstetrics & Gynecology and** Clinical Pathology, Faculty of Medicine, Ain
Introduction: Endometriosis is a disease defined by the presence of endometrial glands and stroma
located outside the uterine cavity. These ectopic implants can be found throughout the pelvis, on and
within the ovaries, abutting the uterine ligaments, occupying the rectovaginal septum, invading the
intestinal serosa, and along the parietal peritoneum. Endometrial implantation at distant sites such as
the pleura, lung, within surgical scars, and along the diaphragm also has been reported. (1). It results
often in subfertility and pain, occurs mainly in women of reproductive age (1650 years) and has a
progressive character in at least 50%, but the rate and risk factors for progression are unknown.
Endometriosis can be classified into four stages: minimal, mild, moderate and severe. The gold
standard for the diagnosis of endometriosis is laparoscopic inspection, ideally with histological
confirmation. (2), however, is an invasive technique and should be performed only after imaging
techniques prove insufficient for confident diagnosis. (3) Lack of a non-invasive diagnostic test
contributes to the long delay between onset of symptoms and diagnosis of endometriosis. (2) Additional
tools are needed for non-invasive classifications in order to reduce the number of unnecessary
laparoscopies without adversely affecting outcomes. Finding specific and more sensitive biomarkers
in endometriosis is critical, because endometriosis is usually diagnosed only in advanced stages, and
there is a high rate of morbidity for this disease. (4)
Aim of the work: The aim of the current study is to assess the validity of serum and peritoneal high
sensitivity CRP and TNF-alpha and plasma cell-free nuclear DNA (ccf nDNA) as biomarkers in early
diagnosis of pelvic endometriosis.
Methods: This study was conducted at the Obstetrics & Gynecology department, Maternity Hospital,
Ain Shams University. This is a case control study of 120 women scheduled for diagnostic
laparoscopy. Laparoscopy was indicated in these women whether for various causes of subfertility or
for chronic pelvic pain between January 2011 and January 2012. The patients were divided into the
following groups: Group I (endometriosis group/ study group) consisted of 80 patients diagnosed to
have endometriosis during laparoscopy. Group I cases were subdivided into two subgroups, Group IA:
consisted of 34 cases with stage 1or minimal endometriosis and Group IB: consisted of 46 cases with
stage 2 or mild endometriosis. Group II (non-endometriosis group/Control group): consisted of 40
cases with no detected pelvic pathology. During the laparoscopy procedure, both peripheral venous
blood and peritoneal samples were withdrawn. Serum and peritoneal levels of high sensitivity CRP
and TNF-alpha as well as plasma levels of ccf nDNA were compared in both groups and in early
stages (minimal and mild) of endometriosis within the study group.
Results: Serum TNF-a, serum hs-CRP and plasma ccf DNA were significantly elevated in cases
compared with the control group. They were also elevated in patients with group IA and group IB as
compared to control group. However, there was no statistically significant difference between cases
and control group as regards peritoneal TNF-a and peritoneal hs-CRP. There was no significant
difference between the group IA and group IB as regards all biomarkers.
Conclusion: Our results showed that serum TNF-alpha , serum hs-CRP and plasma ccf DNA are
highly reliable biomarkers for screening and early diagnosis of endometriosis, but they can not be
used to discriminate between stage I and stage II. On the other hand, peritoneal TNF-a and peritoneal
hs-CRP are non reliable for early diagnosis of endometriosis and can not be used to discriminate
between stage I and stage II of endometriosis.

Background: Bronchial asthma is characterized by lower respiratory tract inflammation associated
with bronchial hyper responsiveness with variable and reversible airflow obstruction. The majority of
asthmatics are sensitized to at least one common allergen.
Aim of the study:
The aim of this study is to determine the association of high-risk asthma with allergy-related
parameters (total serum IgE levels, serum levels of allergen- specific IgE, eosinophil count,
eosinophil percentage ) and pulmonary functions in children.
Subjects and methods: 50 Children aged 8-15 years diagnosed with atopic asthma were enrolled in
the study. Pulmonary function tests, total leukocyte count (TLC), eosinophil count, and eosinophil
percentage were estimated. Total serum immunoglobulin E (IgE) levels and serum IgE levels
specific to antigens from 1 to 9 allergens with class 1 or higher, namely, Dermatophagoides
pteronyssinus (D. pteronyssinus) , Dermatophagoides farina (D. farina ), cat dander , dog dander,
cockroach, egg white, milk, Aspergillus fumigatus, and fish, were measured using UniCAP
fluoroenzyme immunoassay (FEIA).
Results: This study includes 50 participants, 20 (40%) belonged to the high-risk and 30 (60%) to the
low-risk groups. This study revealed no significant association in peak expiratory flow rate (PEFR,
) values between high-risk and low-risk asthma groups (p 0.05). There was no significant
association in forced expiratory volume in first second [ FEV1 (L)] values between high-risk
and low-risk asthma groups ( p 0.05), whereas there was significant association in FEF 25-75%
(forced expiratory flow 25-75%) values between high-risk and low-risk asthma groups ( p 0.05).
There was a significant association between total serum IgE level and high-risk asthma, but TLC,
eosinophil count, and eosinophil percentage showed non significant association with high-risk
asthma. Serum levels of IgE specific to D. pteronyssinus, D. farina, cat dander, and dog dander were
significantly associated with high-risk asthma. The high-risk group had higher serum levels of IgE
specific to D. pteronyssinus ( p < 0.0001), D. farina ( p < 0.0001), cat dander ( p < 0.0001), and dog
dander antigens ( p < 0.0001) compared with those in the low-risk group. There was no significant
association between high-risk asthma and the serum levels of IgE specific to antigens from other
allergens (including cockroach, egg white, and milk). Serum levels of IgE specific to Aspergillus
fumigatus and fish were both negative (class level < 1) in both the high-risk group and the low-risk
Children with higher serum levels of IgE specific to D.pteronyssinus, D. farina, cat dander and dog
dander antigens, and total serum IgE levels, and lower FEF25-75% values belong to the high-risk
asthma group. The characterization of risk factors has enabled us to identify high-risk asthma in
children , leading to better treatment options.

Retinol-binding protein 4 (RBP4) has been identified as a protein contributing to insulin
resistance (IR). As insulin resistance is present in nearly all patients with liver cirrhosis, we
evaluated RBP4 in patients with chronic hepatitis C virus infected patients (CHC). This study
aimed to evaluate the role of serum retinol binding protein 4 (RBP-4) as a predictor for early
detection of insulin resistance (IR) in patients with CHC infection.
Research Design and Methods: Serum RBP4 was measured in 60 non diabetic CHC
Patients classified according to Child- Pugh classification (Child A, Child B, Child C), 20
diabetic CHC patients and 20 age- and sex-matched healthy blood donors served as control
subjects. RBP-4 correlation with the homeostasis model assessment of insulin resistance
index (HOMA-IR) and metabolic factors was investigated.
Results: Serum RBP-4 levels were significantly lower in HCV infected patients and HCV
diabetic patients compared with controls (HCV 16545.17± 10633.16, Diabetic HCV 10310 ±
4371.31, Control 27820.0 ± 9316.46, P< 0.001). In addition, serum levels of RBP-4
significantly decreased between all stages of cirrhosis, with the lowest level in Child C.
HOMA-IR not significantly higher in HCV infected patients compared to control (HCV 5.54
± 3.67, and Control 4.11 ± 2.42). RBP-4 levels correlate positively with GGT (P<0.01),
CHOL (P<0.05) and TG (P<0.05) in HCV Child C, additionally, it shows significant positive
correlation with TG (P< 0.05) in HCV Child B.
Conclusions: Disease severity may limit the role of RBP4 as a predictor of IR in CHC. These
data demonstrate that RBP4 in CHC patients decreased due to reduced hepatic production,
and it is not associated with insulin resistance.

Zoology Dept., Faculty of Science, Mansoura University, Egypt
Introduction:When the drinking water of many species of ducks is changed from
freshwater to saline, their salt glands hypertrophy and the principal cells showed numerous
lateral cell evaginations and abundant mitochondria, enhancing their capacity to excrete salt.
Aim of the work:The purpose of this investigation was to demonstrate and evaluate the
anatomical, histological, and ultrastructural adaptations of the salt gland of the domestic
female ducks associated with high salt osmotic stress.
Material and methods:
The present study was carried out on two groups of female domestic ducks and one group of
wild ducks. Where as one group of domestic ducks was exposed to osmotic stress; imposed
by replacing drinking tap water with 1% sodium chloride solution for two consecutive weeks.
Morphometric measurements as well as histological and ultrastructural aspects of the salt
glands were considered.
Results: The investigation revealed that the weight and size of the salt glands of the salt-
stressed ducks were markedly heavier and larger in comparison to those of the control and
wild ducks. The number and the diameter of secretory lobules as well as the length of
secretory tubules of the salt-stressed group were greater compared to the control ones.The
degree of the proliferation and differentiation of the peripheral cells was distinctly greater for
the salt-stressed than the control and wild ducks. The basal and lateral surfaces of the fully
specialized secretory cell type in the salt-stressed and wild birds were obviously amplified
and in many cases the folds of adjacent cells meshed with one another forming an elaborate
complex of extracellular spaces and intracellular compartments. The cytoplasm of the fully
specialized principal cells displayed abundant endoplasmic reticulum, numerous well
developed mitochondria and deeply well developed basal foldings which increase the

Zoology Dept., Faculty of Science, Mansoura University, Egypt
Background: Many terrestrial non-marine birds have functional salt glands. Their salt glands
are usually quiescent. However, such glands show remarkable levels of phenotypic plasticity
both morphological and physiological as a consequence of drinking saline water.
Objective: The current investigation was conducted to reveal in more detail the different
functional alterations of the duck`s salt glands subsequent to high salt osmotic stress.
Material and methods: The selected avian species were the domestic female (Anas
platyrhyncha) and the wild migratory (Anas clypeata ) ducks. Two groups of domestic and
one group of wild ducks were considered in the present study , each of which included nine
adult ducks. The high salt osmotic stress was induced by replacing drinking tap water of the
domestic ducks with 1% sodium chloride solution for two consecutive weeks. The measured
parameters were included some electrolytes in both serum and glandular tissue. Also, Na-K-
ATPase activity and aldosterone concentrations were considered.
Results: The present study elucidated that serum sodium, potassium, chloride and uric acid of
the wild migratory ducks were markedly higher than those of both salt-stressed and control
ducks. In addition, serum aldosterone concentration of the wild migratory ducks was
distinctly higher in comparison with those of the control and the salt-stressed ones.
Moreover, salt gland tissue homogenate electrolyte contents followed the same pattern as
those of serum electrolyte concentrations. In contrast, the activity of Na-K-ATPase of the
salt gland homogenates was higher in the salt-stressed ducks in comparison to both wild
migratory and control groups.
Conclusion: From the above mentioned results, it was concluded that the peculiar functional
status of the salt gland of the experimentally salt-stressed ducks comparing to the control
may be presented as an adaptive features to satisfy its special demands to eliminate the
remarkable increased levels of sodium chloride load effectively.

Aim of the study: To study changes in pulmonary function tests after esophageal variceal
injection sclerotherapy in comparison to changes after esophageal variceal band ligation.
Patients & methods:
This study was designed as non randomized controlled study. Thirty patients with hepatic
cirrhosis & portal hypertension who were admitted to Hepatology, Gastroenterology and
Infectious Diseases department , Benha university hospital for elective esophageal variceal
therapy (secondary prophylaxis) were classified into group I:15 patients treated with
sclerotherapy by using 5-15 ml ethanolamine oleate and group II:15 patients treated with band
ligation. Patients were subjected for full clinical evaluation including history, general, chest, and
abdominal examination. Laboratory and radiological investigation including complete blood
count, liver function tests, kidney function tests and blood sugar and plain chest x-ray (P.A. and
lateral views) were done. Pulmonary function tests and arterial blood gasses were done before,
one day after and one week after the procedure.
The results revealed , significant decrease in vital capacity in group I one day after injection ( p
0.05),but no significant decrease in vital capacity in group II. There was a significant decrease
in PaO2 in group I one day after injection sclerotherapy ( p 0.05) but no significant changes in
group II and no significant changes in PaCO2 in both groups one day after the procedures. The
study has also revealed no significant changes in FVC,FEV1/FVC and PaCO2 in group I and
group II after procedures. The study revealed significant linear correlation between the decreases
in PaO2 and the percentage decrease in vital capacity( p 0.05). One week after procedure,
pulmonary functions that has been affected in group I returned back to baseline values.
Conclusions: esophageal injection sclerotherapy produces restrictive defect (decrease in PaO2
and vital capacity) in pulmonary functions one day after injection and improved within one
week, while there was no effect for band ligation on pulmonary functions tests.

Background: The cause of growth failure in chronic kidney disease (CKD) is multi-factorial
with linear impairment being a final common pathway of various factors including
malnutrition, increased catabolism, loss of nutrients and antioxidants, and aggressive dietary
restrictions during dialysis .Anemia, metabolic acidosis and persistent micro inflammations
are also causative factors.
Objectives: To assess growth in children with CKD on regular hemodialysis and measure
oxidized high density lipoprotein (OX-HDL), highly sensitive C-reactive protein (hsCRP) and
to discuss their roles as a risk factors of malnutrition among studied cases.
Patients and Methods: The study included 25 children with end stage renal disease (ESRD)
on regular hemodialysis more than 6 months. Their ages ranged from 5-15 years with a mean
of 10.76 years, also 25 of apparently healthy, age and sex matched were included. The study
sample was selected from pediatric dialysis unit and outpatients clinic, of AL-Zahraa
University hospital .Anthropometric measurements were assessed with determination of OX-
HDL and hsCRP serum levels in both cases and the controls.
Results: Anthropometry showed significant decrease in weight, height, body mass index, mid
arm circumference and triceps skin fold thickness in patients when compared to the controls.
100% of patients had high level of OX-HDL and hsCRP, and positive correlation between
OX-HDL and Z-score for Wt and Ht were detected.
Conclusion: Malnutrition, and growth delay are common in children with chronic kidney
disease on regular hemodialysis. High rate of inflammation in dialysis children as there were
high level of hsCRP and OX-HDL. HDL, in regular hemodialysis children loses its protective
function as an anti-oxidant, anti-inflammatory and becomes pro-inflammatory factor.

Value of Multidetector Computed Tomography in Evaluation of Thoracic
Venous Abnormalities among Pediatrics with Congenital Heart Disease
Dalia F Elbeih*, Mervat M El-Gohary *, Naglaa H Shebrya*,Mohammed A Saleh **
* Departments of Radiodiagnosis and** Cardiology, Faculty of Medicine, Ain Shams University.
Introduction: Venous anomalies of the thorax can involve systemic or pulmonary veins and range
from isolated incidental findings to components of more complex anomalies, most often congenital
heart disease (CHD). Although echocardiography and catheter directed cardiac angiography are
generally accepted as the primary imaging techniques for evaluation of CHD, CT and MRI are
important complementary diagnostic tools. Multi-detector computed tomography (MDCT) with its
increasing availability and utility is now becoming a further method of imaging CHD. In light of its
widespread availability, MDCT and 3D imaging are increasingly considered as a viable "one-stop
shop" for preoperative imaging evaluation of cardiovascular structures in selected pediatric patients.
Aim of the work: The aim of this work is to evaluate the role of MDCT in visualization of the
thoracic venous system in pediatrics with congenital heart disease, show prevalence and types of
venous anomalies and to compare this data with echocardiographic findings.
Methods: The studied group included 30 cases referred to us by pediatric cardiologists to be examined
by MSCT angiography of the heart and thoracic vessels. All the patients were known cases of
congenital heart disease and underwent echocardiography. They were referred to answer specific
anatomic question raised by inconclusive echocardiography, to assess suspected systemic and
suspected pulmonary venous anomalies. All patients were subjected to full history taking, clinical
examination and MDCT examination with CT lightspeed VCT XT 64-detectors row scanner (General
Electric, Medical Systems, Milwaukee, Wisconsin, USA).
Results: CTA findings had 77.8 % concordance with echocardiographic findings regarding SVC
anomalies, 66.7 % concordance with echocardiography regarding IVC anomalies and 90 %
concordance regarding pulmonary venous anomalies.
Conclusion: Low dose protocol CTA is a promising method that complementary to Echocardioraphy

Background: Triage of patients with acute chest pain is one of the most important issues
currently facing physicians in the emergency department. Acute chest pain may be a symptom
of a number of serious conditions and is generally considered a medical emergency. The causes
of acute chest pain range from non-serious to life threatening. A rapid, accurate and cost-
effective approach for the evaluation of emergency department patients with chest pain is
Aim of the work: This work aims to emphasize the role of multidetector CT in assessment of
non-cardiac vascular and pulmonary causes of acute chest pain.
Method: The studied group included 89 patients (59 men and 30 women) presented by acute
chest pain. All patients were subjected to MDCT and/or MDCT angiography using a Toshiba 64
detectors CT scanner.
Results: The high spatial resolution and relatively non-invasive nature make MSCT
angiography a strong and serious competitor to established vascular imaging techniques. Having
the additional ability to simultaneously acquire information on other organs, which enables the
early diagnosis of complications.
Conclusion: Continued technical improvements in acquisition speed and spatial resolution of

Department Of Medicine, Biochemistery. National Hepatology and Tropical Medicine Research
Institute and Faculty of Medicine Cairo University.
Objective: Tumour necrosis factor (TNF)-alpha, a prototype proinflammatory cytokine, has been
implicated as an important pathogenic mediator in a variety of liver conditions. Some genetic
polymorphisms in the human TNF-alpha promoter region, such as the G-A transitions -308 and
238, have been shown to influence TNF-alpha expression in chronic hepatitis C virus infection.
Aim of the work: The present study was to investigate the influence that the 308 and 238
TNF- alpha promoter polymorphisms have on the response to interferon and ribavirin therapy in
chronic hepatitis C virus infection.
Patients and methods: One hundred forty patients with chronic hepatitis C virus infection, their
age ranges between (20-56) years, selected from the National Hepatology and Tropical Medicine
Research Institute were included in this study, during interferon and ribavirin therapy and thirty
five healthy individuals were included to serve as controls, the patients and controls were divided
into two groups the first group forty patients and fifteen controls for the detection of TNF-alpha -
308, -238 genotypes polymorphisms, the second group were one hundred patients and twenty
healthy controls for the detection of serum levels of TNF-. All the patients and controls were
subjected to the following history, clinical examination, abdominal ultrasonography and
collection of blood samples for routine laboratory investigation, CBCs and serological assay,
genotyping of 308, 238 TNF-alpha promoter polymorphism and serum levels of TNF-.
Results: There was no statistically significant difference between chronic HCV patients and
healthy controls as regarding TNF-alpha -238 different alleles.
The frequencies of TNF-alpha gene polymorphism with A/G and G/G mutation at 308 were
significantly higher in chronic HCV patients than those in the controls.
The serum level of TNF-alpha was markedly higher in the chronic HCV patients than in the
There were significant association between TNF- alpha gene polymorphism in the 308 A/G,
G/G alleles and increased serum TNF- alpha in CHCV infection.
Conclusion: The results indicate that the TNF-alpha gene polymorphism at position -308 is
associated with susceptibility of chronic HCV infection.
Recommendations: Our major concern was to improve the response to treatment in patients with
chronic HCV infection, whether the disadvantage of having the TNF-alpha -308 allele became
more apparent after interferon and ribavirin therapy is unclear and needs further study that
detecting the polymorphism of the -308 TNF-alpha allele before administering interferon therapy
may be valuable for predicting the treatment response, especially in difficult- to treat patients.

Aim of the work. The present study was planned to investigate the role played by Bee venom in
improving the morphometric and morphological changes induced by carbimazole in pregnant
albino rats and their embryos.
Materials and method .A total number of 60 mature virgin female and 30 male Wistar wistar
albino rats (for fertilization) were used in this study.Pregnancy was ascertained by vaginal
smears.The experimental animals were divided into the following groups:
- (Normal group): in this group the pregnant rats were injected intraperitonealy by distilled water
(The solvent of both carbimazole and bee venom) by dose 1ml/200g.body weight, from day 1 to
day 18 of gestation.
II-The group of treated animals: this group was divided into 3 subgroups:
1-The carbimazole group: this group was divided into2 subgroups, the pregnant rats were orally
injected at a dose 2 and 3mg /200g.body weight, daily from day 1 to day 18 of gestation.
2-The Bee venom group: the pregnant rats were intraperitonealy injected with a dose 0.6
mg/200g. body weight on days 2,3,4,7,8,9,10,11,12,15 and 16 of gestation.
3-The treatment group: the pregnant rats were intraperitonealy injected with Bee venom
at a dose 0.6 mg/200g. body weight 1 hour after the intraperitonealy injection by the 2 doses of
carbimazole (2 and 3mg /200g. body weight).The days of injection for both treatments (Bee
venom and carbimazole) were as mentioned before.
Results. The results of the present study showed that carbimazole treatment with its 2 doses
induced highly significant increase in the body weights of pregnant rats, highly significant
reduction of the uterus weight with shortness of the horns as well as unequal distribution of the
embryos between them, increased number of the resorbed fetuses when comparing with the
control group, Bee venom injection revealed improvement of these changes .The orally
injection of the 2 doses of carbimazole resulted in very highly decrease in fetuses body weights
and lengths; however Bee venom induced obvious improvement as compared with the
carbimazole effects. Orally injection of carbimazole at the dose 3mg /200g body weight showed
increased fetal mortality rate as compared with the control group; however, intraperitonealy
injection of Bee venom resulted in improvement in the rate of live fetuses and never of dead ones
was observed after Bee venom treatment. The 2 doses of carbimazole induced lots of
malformations of embryos such as variations in the size of embryos of the same mother, the
embryos exhibited fragile skin, sub dermal blood coagulation beside edema in different regions
of the fetal body ,as well as malformations of the regions of the eye resembled in exophthalmos
and rostrum region such as cleft lips, beside clubbed fore and hind limbs , kyphosis of the body
of the embryos, exencephaly.Bee venom treatment resulted in control of the changes induced by
carbimazole injection. The fetuses were resembled to those of the control group.
Conclusion: It is clear that bee venom plays an important role in controlling the morphometric
and morphological changes in fetuses of albino rats suffering from hypothyroidism
induced by carbimazole

Chronic exposure to MDMA (ecstasy)induces DNA damage, impairs
functional antioxidant cellular defenses, enhances the lipid
peroxidation process and alters testes histopathology in male rat.

Narcotic Research Department, the National Center for Social and Criminological Research,
3,4-Methylenedioxymethamphetamine (MDMA or "ecstasy") is consumed mainly by young
population. For this reason, it is especially relevant to take into consideration the effects on the
reproductive system. The influence of MDMA on the fertility and reproduction of the male rat
was assessed in this study.
Material and methods: MDMA was administered orally at 0 mg/kg (control), 10 and 30
mg/kg to male rats for 15,30,45 consecutive days followed by 15 days withdrawal. Hormonal,
biochemical, histological and testicular were evaluated in the rats. The present study aimed to
investigate if daily oral administration of ecstasy at low doses(10mg) for 45 days has any
deleterious effects on reproductive functions of male rats. Animals were randomly divided into
four groups of ten rats each, assigned as control rats, or(0mg ecstasy), rats treated with 10mg
ecstasy for, (15,30,45) days, rats treated with 30mg/kg body weight ecstasy for(,15,30,45)days
by oral gavage. The third group(45 days) was followed by 15 withdrawal period(W15).
Results: The activities of superoxide dismutase, catalase, glutathione reductase and glutathione
peroxidase in testicular homogenate were decreased while the levels of lipid peroxidation
increased significantly in the treated rats as compared with the corresponding group of control
animals. In group 30mg, only, arachidonic acid was significantly elevated in the testicular
homogenate while linoleic acid was decresed when compared to control. Testis DNA
fragmentation was observed in 30mg group, but not 10.mg. It is concluded that low doses of
ecstasy exposure(10 mg/Kg) had moderate detrimental effects on reproductive organ system
and more severe effects are likely to be observed at higher dose levels. These results indicate
that ecstasy is directly toxic to primary Leydig cells, and that the decreased percentage of
normal cells and the increased level of DNA damage in ecstasy -exposed Leydig cells may be
responsible for decreased testosterone secretion. The results suggested that graded doses of
ecstasy elicit depletion of antioxidant defence system and induce oxidative stress in testis of

Objectives: There is strong evidence that diabetes results a state of oxidative stress and that
reactive oxygen species contribute to the production of insulin resistance, -cell dysfunction
and both the microvascular and macrovascular long-term complications of diabetes.
Antioxidants are used as supportive therapy in the treatment of DM, so, we use ozone and
vitamin C to study if they can regulate the oxidative complications of DM.
Material and method: twenty male adult albino rats were divided into two groups; group 1:
control group, group 2: alloxan induced diabetic rats which divided into three subgroups.
subgroup1: diabetic untreated rats, subgroup2: diabetic treated with ozone and subgroup 3:
diabetic rats treated with vitamin C. After thirty days of treatment the body weight gain was
detected. Blood sample were collected to1- estimate biochemical parameters as: glucose,
serum insulin, lipid and protein profiles and liver and kidney functions 2- estimate some
hematological parameters. Also, liver samples collected to determine their glycogen content
and pancreatic samples were obtained for microscopic and quantitative evaluation.
Results: in diabetic untreated rats the results showed reduction of gained body weight,
hyperglycemia, and hypoinsulinemia, significant increase in liver and kidney functions and
change in lipid and protein profiles and decreased liver glycogen content. While, O3 and
vitamin C treated rats reported an amelioration of the most toxic effect of alloxan and
returned most of these parameters nearly normal. Microscopically pancreatic beta cells
showed definite vaculation, degeneration, karyolysis and pyknosis in the diabetic group while

patients randomly chosen from out patients, clinic of Ain Shams University hospitals. Tools of the study:
A questionnaire tool developed to collect data about the prevalence of unmet needs for health care in the
previous 6 months. Results: This study conducted on 1316 individuals where 580 (44.8%) reported
unmet health care needs. As regard causes of unmet needs, 33.6% of unmet needs attributed to
accessibility problems, while service availability problems accounted for 57.4% of the unmet needs. The
largest group, accounting for 92.4% of unmet needs was acceptability problems. Conclusions: The
causes of unmet needs attributed to accessibility and availability problems. The most common reported
reason for an unmet health care need was that the too long waiting time, and the high cost of examination.

Background: Colon cancer is a major health problem worldwide and rated among as one of the
top frequent cancers and is a major cause of morbidity and mortality. Treatment outcome is still
not satisfactory and other treatment options are strongly needed. Carbohydrate protein
interactions play a major role in numerous biological processes including cancer. However, the
seeds of Raphanus sativus have never been tested for its anticancer effects on colon cancer.
Therefore, this study aimed at elucidating the anti-carcinogenic effect of Raphanus sativus in
combating chemically (DMH) induced colon cancer.
Materials and methods: polysaccharides extract of Raphanus sativus (RS) was tested for its
ability to reverse the carcinogenic effects of 1, 2 dimethylhydrazine (DMH) which is used for
chemical induction of colon cancer in animal models. Rats were injected with DMH and the
effects of RS extract either concomitant with or after the administration of DMH were evaluated.
. We measured the serum Carcinoembryonic antigen and Carbohydrate antigen as a tumor
markers, Glutathione reducatse and Glutathione S transferase as markers of antioxidant activity
and liver functions.
Results: RS significantly reduced Serum CEA (P<0.01) and CA19-9 (P<0.01) as an evidence of
its anticarcinogenic effect in colon cancer. Moreover, RS was able to significantly increase
activity of Glutathione reductase (p<0.01) and Glutathione- S- transferase (p<0.01) as a measure
of antioxidant compared with DMH untreated group. Also RS was able to significantly increase
activities of ALAT, ASAT and ALP (p<0.01). Chemical analysis of RS done by NMR and paper
chromatography revealed that the polysaccharide in RS was -galactan and the type of bond that
exists between sugar residues is 1, 3 and 1, 6 glucosidic linkages.
Conclusions: This study shows that -galactan of Raphanus sativus has pronounced cytotoxic
effects on colon cancer cell line. Moreover, it reduces serum tumor markers and enhancing
antioxidant activity in the DMH injected animals. This polysaccharide might be a suitable
candidate as a chemopreventive and as an adjuvant therapy for colon cancer.
Key words: Raphanus sativus , -galactan, DMH, colon cancer, tumor markers.
