: Amiodarone AMD (Cordarone) was a benzofuran derivative, used in
management of angina and refractory ventricular arrhythmia. Its effect on the thyroid gland
structure and function was investigated in this study.
Material and Methods: Fifty adult male albino rats were used and divided into three
groups. The first group was consisted of 10 rats which served as control, received distilled water
orally (1ml). The second group was consisted of 20 rats used as therapeutic dose treated group,
received 40 mg/Kg b. w. of amiodarone while the third group was consisted of 20 rats used as a
toxic dose treated group which received 60 mg/Kg b. w. of amiodarone orally daily for three
months. Body weight of animals was determined. Serum concentration of tri-iodothyonine (T3),
thyroxine (T4), thyrotrophin (TSH), interleukin 6 (IL6), tumour marker P53 and tissue residue
for amiodarone in plasma, fat, liver, lung, thyroid gland and heart was determined.
Results: Specimens from thyroid gland were taken and prepared for light and electron
microscope examination. Highly significant decrease in body weight (P<0.001) were observed
in both therapeutic and toxic doses treated groups in comparison to the control one. A very
highly significant increase (P<0.001) of serum (T4 & T3) with Concomitant suppression of
(TSH) (P<0.001). Serum levels of IL6 and P53 showed also a very highly significant increase
(P<0.001). Amiodarone concentration in plasma, fat, liver, lung, thyroid gland and heart showed
significant increase in therapeutic dose treated group and highly significant increase in toxic
dose treated group.
Histopathological examination of thyroid gland of therapeutic dose treated group by light
microscope showed marked evidence of thyotoxicosis in the form of microcystic follicular
changes and peripheral scalloping, cellular degeneration with scanty cytoplasm and vesicular
nuclei appeared. These changes became more severe in toxic dose treated group in the form of
epithelial hyperplasia with atypical nuclear features. Thyroid tissue damage with haemorrhage
and necrosis. Electron microscopic examination showed a remarkable cellular changes in the
form of dilated rouph endoplasmic reticulum, inclusion lysosomes, dilated Golgi bodies,

Department of Zoology, Faculty of Science, Mansoura University, Mansoura, Egypt.


This work has been carried out to detect the effect of tigernut tubers as an antidiabetic
plant on some biochemical parameters in streptozotocin (STZ)-induced diabetic rats. Diabetes
mellitus was induced by a single intraperitoneal injection of 45 mg STZ /kg body weight. The
present results indicated an increase in both serum glucose level and liver glucose-6-
phosphatase (G6P) activity in STZ-diabetic rats. In addition, a significant decrease in serum
insulin level and liver glycogen content was recorded in the same rats. Moreover, serum total
lipids, total cholesterol, triglycerides and LDL-cholesterol levels revealed a significant increase,
while a decrease in the level of HDL-cholesterol was observed in STZ-diabetic rats. The activity
of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline
phosphatase (ALP) showed marked increase in STZ-diabetic rats. On the other hand, tigernut-
supplemented diet (25% w/w) for two or four weeks recorded a significant improvement in all
the above biochemical parameters affected by STZ injection especially after four weeks of
treatment. Therefore, it was concluded that tigernut tubers had appreciable hypoglycemic and
hypolipidemic effects on STZ-diabetic rats.

Hala Galal El-Tantawi
Department Of Zoology ­Faculty Of Science - Ain Shams University


Objective: This study was carried out to evaluate the protective effect of ginger Zingeber
extract (ZOE) against the acrylamide (AC) which is an industrial chemical used in
water treatment and it is synthesized during cooking of starch food at high temperature.
Method: Thirty adult male albino mice, each weighs 20-25 g were divided into three
groups (10 mice/group): (I)control group. (II)acrylamide treated group. (III) acrylamide &
ginger group. Acrylamide was given to experimental animals in the drinking water at a non-
lethal dose of 200 p.p.m for 10 weeks (3 days/week). Ginger extract was orally administrated at
50 mg/L (~5 ml/day) for 10 weeks (3 days/week). The ileum samples were collected for light
microscope study and for scanning and transmission electron microscope examination.
Results: This study revealed that acrylamide induces pathological changes of the ileum of
the treated mice specially the absorptive epithelial cells. The scanning electron microscopic
study revealed damage of the ileal villi, some red blood corpuscles appeared at the site of
damage. The transmission electron microscopic examination clearly demonstrated degeneration
of most cell organelles as mitochondria, deterioration and degranulation of the rough
endoplasmic reticulum, dilatation of Golgi apparatus.
Conclusion: The administration of ginger extract decreased the histological alterations

Introduction: The present study deals with the effect of oat bran (Avena sativa L.) in the
treatment of hypercholesterolemia in comparison with a hypocholesterolemic drug, atorvastatin,
on hypercholesterolemic liver in male albino rats.
Material and Methods: For this purpose four groups of rats (each containing 6 rats) were
used. The first group was used as a control, the second was cholesterol-fed group with
cholesterol (0.5% w/w) for 6 weeks. The third group was oats-fed hypercholesterolemic rats on
oat supplemented diet (20% w/w) for 4 weeks and the forth group was atorvastatin-treated
hypercholesterolemic rats orally at a dose of 0.18 mg/Kg body weight/day for 4 weeks.
Results: The biochemical results revealed a significant increase in serum LDL-C and a
significant decrease in HDL-C level. In addition the activity of AST was increased in
cholesterol-fed rats. Meanwhile, the treatment with oat soluble fiber or atorvastatin drug
improved the above mentioned parameters. The histopathological examination of liver sections
of cholesterol-fed group showed accumulation of lipid. Hepatocytes showed ballooning
degeneration and manifested clear necrotic signs. Inflammatory cellular infiltration was found
around the blood vessels, mild fibrosis near the portal blood vessels. However, liver impairment
was reduced markedly in the liver of oat soluble fiber fed rats rather than atorvastatin drug
treated rats.
Conclusion: The present study, however, confirms that the cereal grain oat may have
potent beneficial health effects in reducing LDL cholesterol and should be included in the
prudent diet of individuals with hyperlipidemia.

(AEA) Cairo, Egypt.


Backgrounds: The efficacy of antioxidant supplementation and oxidative stress of
gamma irradiation for and during pregnancy is poorly established. The present study aimed to
detect the toxic effects of high dose of folic acid and / or gamma radiation on the placenta of
pregnant rat and the liver of their fetuses.
Material and Methods: Pregnant albino rats were divided into four groups. The first
group served as a control, the second group received oral intake of folic acid (5 mg/kg) from the
5th to 20th day of gestation, the third group was irradiated with gamma radiation (3Gy, as
fractionated doses (1Gy/ 3 times) on each 5th, 10th and 15th days of gestation, the fourth group
was imanaged with combined treatment.
The pregnant rats were sacrified after 20 days of pregnancy and samples were taken from
the blood, placenta and the fetal liver for the morphological, biochemical and electron
microscopic studies.
Results: The present results showed a significant elevation in serum gamma
glutamyltransferase (GT), lactate dehydrogenase (LDH) in placental tissue of pregnant rats
associated with an increase of phosphorus content in liver of fetuses. Fetal malformations
including: protrusion, anotia, short neck dactylomegaly, subcutaneous haemorrhage, paralysis in

Effect of Trifolium alexandrinum extracts on the kidneys of diabetic rats:
Biochemical and histological study.

Maisaa M. AL-Rawi
Biology Department, Girls College, Makkah, Saudi Arabia.


Diabetic nephropathy is one of the most common and most devastating complications of
diabetes. During the course of diabetic retinopathy, the glomeruli are slowly destroyed, usually
with no detectable signs until the later stages of the disease, when the kidneys filtration process
can no longer function. Throughout this disease, blood flow through the kidneys increases
"hyperfiltration", and the kidneys become enlarged. Damage to the glomeruli becomes evident,
as well as a condition known "microalbuminuria", in which a blood protein, albumin, leaks into
the urine. This loss of proteins and other nutrients in the blood progresses, as does the damage
to the glomeruli. The kidneys progressively lose their ability to filter waste until the final stage,
kidney failure, occurs. On the other hand, some species of the plants were reported having
remarkable medical importance. Trifolium alexandrinum is a medicinal herb; it has been shown
to improve the flow of blood through arteries and veins in diabetic patients. Therefore, the
present study aims to determine the possible improvement effects of different extracts of
Trifolium alexandrinum (CF) on some biochemical and histopathological changes in the kidneys
of streptozotocin-induced diabetic rats. Sixty adult male albino rats (210 ± 5 g) were injected
(IP) with streptozotocin (STZ) (50 mg/kg b.wt) for induction of diabetes. Animals were
classified into five groups. Daily intake of water, hexane and ethanolic extracts of T.
alexandrinum in drinking water for 4 weeks after diabetes induction were used. Urine glucose
was detected every week. Serum total protein, albumen, urea, uric acid and creatinine levels
were tested. Data were expressed statistical to elucidate the differences between treated and
control groups. The kidney paraffin sections of control and treated groups were stained with
haematoxylin and eosin for histological studies. A single dose of STZ induced diabetes
produced remarkable effects on both structure and function of the rat kidneys. The kidney
exhibited damage of some renal corpuscles revealed glomerular mesangial cells hypertrophy,
dilatation of renal tubules together with necrosis of their lining cells. Serum total protein,
albumen, urea, uric acid and creatinine were significantly increased. Daily urine volume and
consequently renal excretion of albumen, urea, uric acid and creatinine were significantly
increased. However, remarkable improvement of the renal structure and function of diabetic rats
was observed after treating with Trifolium alexandrinum extracts especially the group treated
with water extract.
Conclusion: Extracts of Trifolium alexandrinum improved histological and biochemical
alterations of the kidneys noticed in STZ-diabetic rats. These effects may be due to the presence
of a high content of flavonoids which acts synergistically as antioxidants.

The Protective Effect of Curcumin Against Gentamicin-Induced Renal
Dysfunction and Oxidative Stress in Male Albino Rats

Faculty of Medicine Al -Azhar University-Cairo


Background: Generation of free radicals in the renal cortex plays an important role in the
pathogenesis of gentamicin-induced nephrotoxicity. Curcumin, the yellow curry pigment
isolated from turmeric, has been confirmed to have a strong antioxidant and free radical
scavenging actions. In the present study, we investigated the possible protective effect of
curcumin against gentamicin-induced nephropathy in male albino rats.
Methods: Thirty two male albino rats were divided into 4 equal groups (Gr.): (Gr.I)
control, injected i.p with 1cc isotonic saline solution/day for 8 wks; (Gr.II) received 200
mg/kg/day curcumin (Cur. ) orally, suspended in normal saline, for 8 wks ; (Gr.III) injected I.p
by 100 mg/kg/day gentamicin (Gen.) for 8 days followed by 1cc saline I.p thereafter; (Gr.IV)
(Cur./Gen.) received 200 mg/kg/day Cur. for one week before starting Gen injection (100
mg/kg/day) for 8 days during which Cur. was received concurrently with Gen then Cur
administration was continued thereafter throughout the rest of the study (6 wks). Body weight
was recorded weekly. Renal function was evaluated by measuring the 24 h. urine output, the
concentrations of plasma creatinine, blood urea nitrogen (BUN) and creatinine clearance. Also,
kidney weight and the parameters of oxidative stress: reduced glutathione (GSH), thiobarbituric
acid reacting substance (TBARS) and the activities of superoxide dismutase (SOD), catalase and
glutathione peroxidase (GPX) were measured in kidney tissue.
Results: The Kidney weight, plasma creatinine, BUN and 24 h urine output were
significantly increased while the body weight and creatinine clearance were significantly
decreased (P < 0.0005), in rats treated with Gen. as compared to control. While Cur. could
significantly normalize the previous parameters. In addition Gen. caused oxidative stress in
kidney as seen by significant increase in TBARS level, and significant decrease of catalase,
GSH, SOD and GPX activities (P < 0.0005), However, Cur. could normalize all the above
parameters as compared to control.
Conclusion: Our data indicate that Cur. could suppress renal toxicity by blocking
oxidative injury in the kidney and restore the antioxidant enzymatic profile. The renoprotective
effect of Cur. is also evident by a remarkable improvement of renal function in Gen. injected
rats. So Cur. can be used as a potent protective agent against renal oxidative damage mediated
by Gen.

In the present study the possible anti-morbidity effect of secretory excretory products
(SEP) of Schistoma mansoni eggs (given to mice before infection) was investigated. Multiple
small doses of SEP were injected intra-peritoneally into albino mice (100 g of purified SEP
followed 2 weeks later by two booster doses of 50 g each at weekly intervals). Data revealed
reduction in CD4+ cells and increase in CD8+ cells of hepatic granuloma in SEP-immunized
infected group, resulting in significant decrease in CD4+/CD8+ ratio, in comparison to infected
control group. The serum cytokine level of both TNF--alpha and IFN-gamma were also
significantly decreased. Histopathological examination of liver revealed remarkable increase in
degenerated ova within hepatic granuloma which decreased in diameter (12%). Significant
reduction in worm burden (46%) and tissue egg loads (42.8% and 50% for hepatic and intestinal
ova respectively) were observed. Mean while decreased percent of immature stages with
increase in percent of dead ova in Oogram pattern was recorded. This work may help in

The sequential mutational events which may underlie the tumorigenesis of thyroid
neoplasia are gradually becoming apparent. To clarify the role of P53 and cyclin D1 in the
oncogenesis and tumor progression of thyroid neoplasms, we examined the immunoreactivity of
these proteins in one hundred and thirty (130) thyroid tumors originating from the follicular
epithelium using immunohistochemistry. The tumors were divided into two groups group I:
included thirty five (35) follicular adenomas and group II: included ninety five (95) follicular
carcinomas; 65 of which were well differentiated (WDC) while the remaining (30) were poorly
differentiated (PDC). P53 positivity was more frequent in group II (20/95; 21.1%) than in group
I (6/35; 17.1%) and in PDC (11/30; 26.6%) than WDC (9/65; 13.8%). On the other hand, cyclin
D1 positivity was frequent in WDC (21/65; 32.3%) and rarely seen in adenoma group (2/35;
5.7%). Co ­positivity for P53 and cyclin D1 proteins was more observed in PDC (5/30; 16.7%)
than in WDC (3/65; 4.6%).
The study suggested that cyclin DI may be involved in the thyroid oncogenesis and
concluded that both proteins may be incriminated in the progression of follicular thyroid
neoplasms. Moreover, we found that age at the time of diagnosis, the histologic differentiation,
necrosis in primary tumor, extrathyroidal invasion and the presence of distant metastases are
important prognostic and risk factors. In addition, our study revealed that the detection of P53,
but not cyclin D1, in primary follicular carcinomas is a significant independent prognostic
indicator which, together with the above mentioned important prognostic factors, may be of
value in the theraputic planning of these tumors.

Background and Aims:
Many studies have shown the relative roles of hepatitis B and C
viruses in hepato-carcinogenesis. The aim of this study is to define the independent and
interactive roles of some cytokines namely, TNF , IL-6, IL-1 together with NO and TEARS
in the genesis of HCC following the infection with such viruses.
Patients and methods: Blood samples were taken from 58 patients with hepatocellular
carcinoma and were divided into four groups: a) 28 patients with HCV, b) 10 patients with
HBV, c) 11 patients with B+C, d) 9 patients without viral infection. In addition, 20 healthy
subjects served as control group for each, TNF , IL-6, and IL-1 were measured using
ELISA technique, in addition to NO and TBARs using chemical methods.
Results: Patients with coinfection B-C viral infection showed the highest levels in
studied parameters. Patients with HCV and HBV separately showed more or less similar results.
However, patients without viral infection showed the least higher levels comparing to the
control group.
Conclusion: Cytokines in addition to NO and TEARS have a definite role in hepatic
carcinogenesis. Coinfection with the two viruses carries a synergistic risk factor of
hepatocellular carcinoma development. Depending on the results of the studied parameters
HCV did not show predominancy on HBV. Further studies are needed to clarify the exact
mechanism of carcinogenesis especially in HCV patients.

A strong relationship between aging and diabetes mellitus has been clinically suggested,
however, none of the previous published data had clearly focused on the age-related
cytomorphological changes in the pancreas which are the goal of this study.Three groups of
male apparently healthy rabbits have been used, ten animals each; classified as group-1 (3-
5months old); group-2 (9-12 months old) and group-3 (24-36 months old). After sacrification,
sections from the pancreas were stained by Haematoxylin and Eosin (H&E), Gomori trichromic
stain & ultrastructurally to detect aging histologic changes as well as immunohistochemically
to identify insulin and glucagon secreting cells using their appropriate monoclonal antibodies .
A progressive histological distortion with fibrosis and fatty changes were directly
proportional to age, being mild in group-2 and severe in group-3. Morphometric studies by
computerized image analysis showed that the mean number of islets was significantly higher in
group2 (8.98±1.51), lowest in group-1 (5.08±1.48) and intermediate in group-3 (6.37±1.37).
The mean diameter and square area of islets were significantly higher in group-2 compared to
other groups (P< 0.05). The mean number of cells per islet & their secretary granules were
significantly (P <0.05) higher in group-2, intermediate in group-1 and lowest in group-3.In
contrast, the mean number of cells per islet and their secretory granules were insignificantly
(P< 0.05) higher in group -2, intermediate in group-3 and lowest in group-1.Also, the / ratio
( cells/ cells) was greatest in group-2 (3.059:1), intermediate in group-1 (3.37:1), and lowest
in group-3 (2.479:1).
The increased number of cells may be due to a compensatory process to correct the
hormonal feedback mechanism of insulin .The results of this work suggest that cells are
generally more vulnerable to aging, an observation which might be correlated clinically with
higher incidence of diabetes in older ages.

Mental disability can interfere with education and scholastic achievement. It
can lead to school dropout and minimize opportunities to participate in the labor force.
Moreover, disabilities affect the overall health and psychological state of the individuals.
Objective: The aim of the present study was to assess the nutritional status of mentally
disabled children in Egypt on the basis of anthropometric indicators and laboratory data.
Subjects and Methods: Across sectional study was conducted on 639 mentally disable
children aged 6-<14 years (422males and 217females), from urban areas. They were classified
into two age groups (6-<11& 11-<14 years). The following variables were determined using Z
score indicator of weight for age, height for age and weight for height. Also, body mass index,
mid arm circumference and triceps skin fold thickness percentiles were determined. Laboratory
investigation including blood hemoglobin concentration and plasma levels of vitamin A and -
tocopherol as well as plasma zinc, copper and magnesium concentration were estimated.
Results: Prevalence of underweight was 14.1% by Wt/age Z score. Stunting was
estimated among 33.5% with significantly higher prevalence in older children. Muscle &fat
depletion was detected in 30.2%, with significantly higher prevalence among males than
females. Depleted fat store was detected in 14.7% of children. Wasting was documented in
14.1% of children by BMI percentile, and was significantly higher among males than females.
No significant difference was detected between male and female handicapped children
regarding mean blood hemoglobin values as well as mean plasma levels of the measured
vitamins and minerals, except for mean plasma zinc level. The overall prevalence of iron
deficiency anemia was higher in males (41.5%) than females (37.1%). Deficiency of -
tocopherol was more prevalent than that of vitamin A. The overall prevalence of deficiency of
zinc, magnesium and copper was 1.8%, 40%, and 25.3% respectively. The decline in
anthropometric measurements was associated with the decline in socioeconomic status.
Conclusion: Malnutrition as revealed by anthropometric variables and micronutrient
deficiency occurs with a high prevalence among mentally disabled children and almost
increased with age and low socioeconomic level.

Parasitic diseases represent a major cause of morbidity and mortality in childhood in most
parts of the world. Hygiene and play habits make children especially vulnerable to schistosomal
and parasitic infections. The aim of this study is to define the prevalence of different types of
parasitic infections, to define their risk factors and to determine their impacts on health and
scholastic absenteeism and achievement of rural school students in Sohag Governorate, Egypt.
A cross-section, analytical study design was chosen to perform this research on 960 rural school
students. All the students were interviewed and examined clinically and laboratory. The study
showed that 38.5% of the students were infected by parasites. Entaemoeba histolytica,

Diabetes mellitus is a chronic syndrome affecting carbohydrate, fat, protein and nucleic
acid metabolism. The current study was undertaken to elucidate the possible role of vitamin E
and alpha lipoic acid in combination as an antioxidant and a biological membrane stabilizer in
the protection against early complication of diabetes. Administration of alloxan (125 mg/kg wt,
i.p.) to rats resulted in hyperglycemia, hyperinsulinemia, hypercholesterolemia,
hypertriglyceridemia, hyperlipidemia, increase in plasma levels of urea, blood urea nitrogen
(BUN), creatinine, uric acid as well as pancreatic thiobarbituric acid reactive substances
(TBARS) and glutathione (GSH) content of both liver and retina. These changes were
accompanied with significant decrease in plasma total protein, tumor necrosis factor (TNF),
hepatic catalase activity (CAT), and TBARS level of both liver and retina as compared to
control group. However, plasma levels of calcium ions (Ca+2) and nitric oxide (NO) as well as
pancreatic GSH content were not changed. On the other hand, the daily treatment of the diabetic
rats with antioxidant mixture attained a reduction in plasma levels of glucose, cholesterol,
triglycerides, total lipids, urea, BUN, creatinine, uric acid, TNF, pancreatic TBARS level as
well as GSH content of both liver and retina. In contrast, the daily treatment caused an increase
in plasma levels of insulin, total proteins, hepatic CAT activity and pancreatic GSH content as
compared to diabetic rats. However, plasma levels of Ca+2 and NO as well as TBARS content of
both liver and retina were not affected. In conclusion, it is obvious from the present study results
that early stage (two weeks) of diabetes induce deteriorate changes in carbohydrate, lipid,
protein and nucleic acid metabolism accompanied with increasing of oxidative stress in
pancreas as compared to both of liver and retina. Moreover, the data of present study indicated
the effective role of vitamin E and alpha lipoic acid combination in combating the oxidative
stress via its improvement to metabolism of carbohydrates, lipids, proteins and nucleic acids in
addition to its free radical-scavenging and antioxidant properties.

Background: Two chelating agents (Carnosine and DMSA) were used to study their
labeling conditions with technetium-99m followed by biological distribution investigation.
Molecular studies were done via PCR/RFLP analysis of angiotensin II subtype II receptor gene
for monitoring their antioxidant activity through free iron chelation leading to inhibition of
Fenton reaction.
Material and methods: Carnosine was labeled by mixing 4 mg with 30 mg glucose and
25 g SnCl2.2H2O, followed by pertechnetate and stand at room temperature for 60 minutes.
Minor modification was done to prepare 99mTc(V)-DMSA tracer in one step, by adding

enough to block radiation induced oxidative stress and Moderate antioxidant activity of DMSA
was achieved by chelating free iron and iron released through oxidative stress. Maximum
protection was achieved through the dual action of both DMSA and carnosine.
Conclusion: moderate and high labeling yield were achieved for both 99mTc(V)DMSA and
99mTc-canosine respectively with higher selectivity of the former to tumor sites and maximum
protection were achieved by the dual action of both chelating agents.

Faculty Of Medicine, AL-Azhar University-Assuit


Arsenic is an environmental toxicant and a human carcinogen.
Epidemiology studies link human arsenic exposure to various diseases and cancers, including
liver diseases and hepatocellular carcinoma. From this point of view, this study is designed to
investigate the effects of arsenic histologically and histochemically on the liver of adult male
Material and methods: twenty adult male rabbits were used and divided into four groups.
Each group consisted of five rabbits, one group used as a control given an equivalent volume of
distilled water and three groups given sodium arsenite in distilled water for 6, 12 and 18 weeks
respectively. Paraffin sections from all groups prepared and stained by haematoxylin and eosin,
and periodic acid-schiff.
Results: histological and histochemical changes in arsenic groups were marked
vacuolation of hepatocytes with focal areas of hepatocellular degeneration. Loss of hepatic
architecture was also observed. Marked dilatation and congestion of the central veins and
mononuclear cellular infiltration were obvious. Quantitative analysis of intracellular glycogen
stores of all groups using image analyzing system revealed gradual significant depletion of
intracellular glycogen stores.
Conclusion: it was concluded that arsenic is a hepatotoxic agent in the adult male rabbits.

The objective
is to study the histological influence of the bioactive glass on bone healing
in surgically created holes in rat's femur.
Methods: The two wall holes were made in the right femurs by 2-mm drill, filled with
bioactive glass in the examined rats. Another two wall holes were made similarly in the right
femurs of other group of rats without filling with bioactive glass and used as the control group.
Animals were regularly examined over a period of five weeks for bone healing.
Result: Histological examination of both control and treated sites showed newly formed
bone. The newly formed ostoid tissue was significantly increased in the treated holes in the form
of foci of newly formed bone around and within the glass particles. In the control group, the
junctional epithelium migrated up to the base of the hole.
Conclusion: The treated animals with bioactive glass had better healing than control. The
bioactive glass particles have osteo-conductive property as well as osteo-stimulatory capacity.
The graft material showed a promising inhibition of greater cementum deposition in the bone
holes. We can use it in Osteosurgery as it can promote bone healing.
Key words: Bioactive glass, bone hole, bone healing, histological changes.

Genotoxic effects of agricultural chemicals are of special concern because of their
generally irreversible effects and the long latency associated with their manifestation. These
effects include heritable genetic diseases, carcinogenesis, reproductive dysfunction and birth
defects. The present study was carried out to investigate the effect of the organophosphorous
insecticide "profenofos" on white albino rats. The rats were treated for 28 days with three
different doses of profenofos (1/20 LD50, 1/40 LD50, and 1/80 LD50). Then the animals were
left without treatments for 14 days for possible recovery. The genotoxic effect of the pesticide
was evaluated by using the micronucleus assay in the bone marrow and polymorphism of
glutathione S-transferase (GST) by polymerase chain reaction (PCR). The results demonstrated
that the treatment with profenofos caused a significant increase in the frequencies of
micronucleated polychromatic erythrocytes. Results of polymorphism of both GSTM1 and
GSTT1 showed positive genotype in the control group. While the results of GSTT1
polymorphism in the treated rats showed positive genotype in all doses of profenofos. The
GSTM1 polymorphism showed positive genotype in the high and medium doses (1/20 LD50
and 1/40 LD50) but not in the low dose (1/80 LD50), where the GSTM1 was null (negative)
genotype. After the recovery period the polymorphism of GSTM1 and GSTT1 was found to be
positive genotype, except with the low dose (1/80 LD50) showed null genotype for GSTM1
gene. The histopathological data showed that profenofos exhibited histopathological changes in
liver, kidney, spleen and tests. Liver showed hepatic cell damage with degenerative changes.
The kidney showed heamorrhages, edema, necrosis and glomeruli shrinkage. The spleen
showed slight deplesion of the lymphocytes of the white pulp. The tests showed interstitial
edema and severe necrosis of spermatogenesis. From these results we concluded that the
profenofos exert genotoxic and histopathological effects on albino white rats.

In this work the effect of excess body weight on house works and some physiological
parameters were conducted on twelve females' university students. The students were divided
into a control (normal weight) group and experimental (overweight) group. The weakly cleaning
of the living room was chosen as house work. A room was prepared as a living room with some
furniture like tables, chairs, a sofa and cupboard in addition to a carpet on the ground and
curtains on the walls. Observation of complexion, tremors, behavior reflecting boredom , level
and time of performance as well as any complaint as tiredness, back pain, leg pain. Some
physiological parameters as pulse, blood pressure, respiratory rate forced respiratory capacity
and expiratory time were measured.
The results showed that overweight has passive effect on time and level of performance;
also it affects the circulatory functions more than the respiratory functions. So house works are
not considered as hard work and not sufficient to reduce body weight in overweight women.
Also house works can be tolerated and there is no need to restrict activity to guard against
respiratory distress

Design: retrospective study
Patients & Methods: the study was conducted on 75 patients suffering PND with a male
to female ratio 59 to 16 done between May 2004 to June 2007 with a follow up range 8-13 and a
median of 10.7 months. Sixty four patients had sacrococcygeal disease, 9 patients had umbilical
disease, and 1 patient had suprapubic while 1 patient had axillary disease. For sacrococcygeal
disease Limberg operation was done in 26.5% (n=17), abscess drainage and curettage in 31.2%
(n=20), Bascom operation in 23% (n=15) while conservative treatment in 31.2% (n=20).For
umbilical disease, omphalectomy was done in all cases (n=9). Conservative treatment was done
for suprapubic disease while excision followed by primary closure was done in axillary disease
(n=1) after failure of conservation.
Aim: to evaluate different modalities in treating pilonidal disease (PND)
Results: For sacrococcygeal disease, patients who received Limberg procedure (n=17)
showed complete resolution in 88.2% (n=15) with recurrence rate 11.8% (n=2). Those who
received Bascom operation showed complete resolution after all procedures with no recurrence
during the follow up period. Patients who received conservative treatment (n=20) showed a
success rate of 70% (n=14) with recurrence rate of 30% (n=6) who received Bascom procedure
later for their recurrence. For umbilical, suprapubic and axillary disease; omphalectomy,
conservative treatment and excision with primary closure were used respectively with no
complications encountered.
Conclusion: For sacrococcygeal disease, Bascom operation was found to be superior
over other modalities with respect to smooth postoperative period and early healing while in
umbilical disease conservation shows higher success rate.

Tinea capitis is a common condition seen by clinician in all setting through out the world.
Several investigations of the various superficial mycosewere carried out in Egypt, but they were
mainly confined to urban areas.
In the present work, the predominant species causing dermatophtosis in Assuit
Governorate were investigated, this is represented in rural and partially suburban communities.
A clinical and mycological study was done for hundred patients attending the Dermatology Out-
patient Clinic in Al- Azhar University Hospital in Assuit City. The ages of patient ranged from
3 to 20 years .

60% of cases were between 6-10 years of ages.
Males were affected more than females in a ratio of 3: 1
60% of cases were from rural areas. Positive history of contact with animals was
present in 40%.
The most common clinical variety was scaly type 55% followed by black dot 22%,
kerion 20%, and lastly favus 3%.
Direct microscopic examination was + ve in 80% of cases. Positive culture results were
obtained in 90% of cases.
The results indicated that Zoophilic dermatophytes was the predominant causative
species in these regions. Five dermatophytes were identified namely: M.canis was the
