A cross-sectional design was carried out on 827 students from general and technical
secondary schools in Cairo. The aim of this study was to determine the prevalence of risky
behaviours among the studied students, to assess their relation with sociodemographic factors
and psychological problems and to explore student's attitude toward these behaviours. The data
were collected by a standardized interviewing form. Different psychological symptoms were
assessed using Middle Sex Hospital Questionnaire. The study showed, 54.1% of the students
were having unhealthy diet and tobacco smoking behaviours. Also, all the risky behaviours,
except absence of physical exercise practice and suicide attempt, were more common among
boys. The most important sociodemographic risk factors were; positive family history of risky
behaviours, one parent family and the student's work beside studying (OR=7.11, 4.07 and 3.37,
respectively). The most important reasons for unhealthy diet, carrying weapon and engagement
in casual sex were imitation (55.2%), to feel grown up (47.1%) and peer pressure (39.1%),
respectively. While, the most common psychological problem was hysteria (15.1%) and the
most common neurotic trait was sadness (41.9%). The most important psychological problems
risk factors were obsession and hysteria (OR=5.53 and 4.59, respectively). While, the most
important neurotic traits risk were irritability and sadness (OR=9.53 and 8.05, respectively). No
awareness to the reported risk was present among 96.4% of the students having the risky
behaviours (OR=6.41).

Metallothioneins (MTs) constitute a family of several intracellular, low molecular-weight
proteins with a high affinity to various heavy metals. They are involved in metalloregulatory
functions such as cell proliferation, growth, and differentiation. The goals of the present study
were to investigate the expression of MT in hyperplastic, dysplastic and neoplastic prostatic
lesions and to correlate its expression with histologic grade of prostatic carcinoma.
This study was performed on Formalin fixed and paraffin embedded tissue blocks from 8
patients with benign prostatic hyperplasia (BPH), 6 patients with prostatic intraepithelial
neoplasia (PIN) and 30 patients with prostatic carcinoma (PC) using streptavidin-biotin
technique. The histologic grade was defined and the carcinoma cases were divided into 8 low
grade (Gleason 2-4), 12 moderate grade (Gleason 5-6) and 10 high grade (Gleason 7-10)
Normal and benign prostatic tissues showed patchy MT staining of epithelial cells. All
cases of PIN, 20 out of 30 PC cases (66.7%) showed positive staining for MT. MT expression
significantly increased from low to high grade tumours. The proportion of MT positively stained
cells was directly correlated with histologic grade of PC. The epithelial cells lack uniformity in
staining intensity, but the percentage of strongly positive cells increased with increasing the
histologic grade of PC.
The high incidence of MT expression in PIN in this study suggests that it is associated
with early prostate tumorigenesis. Also MT expression was directly correlated with histologic
grade of PC suggesting that MT may be a useful marker for predicting prognosis of cancer

Bening paroxysmal positional vertigo (B.P.P.V) is one of the most common vestibular
disorders.During the last years, it has been attributed to cupulolithiasis or canalithiasis of the
posterior semicircular canal.This randomized study was done to determine the effectiveness of
two different physical therapy approaches and to determine if a single treatment approaches is
enough.In this prospective study 80 patients received either a single treatment based on the
hypothesis that the vertigo and nystagmus of (B.P.P.V) are due to debris adhering to the cupula
of posterior semicircular canal (cupulolithiasis), Semont maneuver, or a single treatment based
on the hypothesis that the debris is free floating in the long arm of the posterior semicircular
canal (canalithiasis), Epley maneuver.Treatment outcome was classified as asymptomatic,
improved and no change.
Analysis of the results of this study revealed that at the end of the first session , out of 80
patients, 60(75%) were asymptomatic ; 14(18%) improved ;6(7%) showed no change. Follow­
up showed that 8 patients developed recurrence. After a second session to 22 patients (8
recurrences, 10 improved, 4 had no change) ,17 became asymptomatic.This means that at the
end of the seconed session ,69 (86%) of 80 patients became asymptomatic ; 9(11%) of 80
patients improved ; 2(3%) of 80 patients showed no change.
In conclusion , this study shows that 1) The success rate of Semont's maneuver was up to
80%, so it is much better than Epley maneuver 70% after the first session. 2)Recurrent cases are

The present study aimed to clarify the effect of aqueous extracts of five plants (Nigella
sativa , Aloe vera, Ferula assafoetida, Boswellia carterii Birdw and Commiphora myrrha) and
their mixture on liver and kidney functions and protein profiles. Eighty adult male albino rats
were divided into eight groups, the first served as control group, other groups were injected with
alloxan(120mg/kg b.wt). The second group served as diabetic rats, the third were treated with a
mixture (0.1g/100g b.wt), the fourth was treated with Nigella sativa (0.1g/100g b.wt), the fifth
was treated with Aloe vera (0.05 g/100g b.wt ), the sixth was treated with Ferula assafoetida
(0.1g/100g b.wt), the seventh was treated with Boswellia carterri Birdw (0.1g/100g b.wt) and
the eighth group was treated with Commiphora myrrha (0.05 g/100g b.wt ). After thirty days of
treatment half of each group was decapitated and the other one was left for 15 days without any
additional treatment as recovery period to followup their hazards if present.
The results revealed highly significant increase (p<0.01) in serum transaminases
(aspartate ( AST ) and alanine (ALT)), alkaline phosphates (ALP), total bilirubin, urea and
creatinine and recorded highly significant decrease (p<0.01) in serum total protein , albumin and
globulin concentrations in the diabetic group when compared with normal rates. Otherwise, all
plants extracts treated groups showed insignificant changes in the previous parameters when
compared with control one .
It seams, therefore that the water extracts of these plants and their mixture have protective
effect against the side effects of alloxan on liver and kidney.

Objective. The aim of this work was to determine if a correlation between lateral epicondylitis
and abnormalities of the lateral ulnar collateral ligament is found on MR imaging.

Subjects and Methods. The Study group comprised 50 consecutive patients who were referred
for MR imaging to rule out lateral epicondylitis. On MR imaging "lateral epicondylitis" was
defined as increased signal intensity of the extensor tendons close to their insertion on the lateral
epicondylitis. The severity of the lateral epicondylitis was graded as mild, moderate or severe.
The origin of the lateral colleteral ligamantous complex was characterized and the lateral ulnar
collateral ligament was normal, thickened, partially torn or torn. Sixteen patients underwent
elbow surgery after the initial MR examination.

Results. In 15 patients, MR imaging revealed characteristics of mild lateral epicondylitis. In 13
of these patients the lateral ulnar collateral ligament was normal. One patient showed a
thickened lateral ulnar collateral ligament and one patient had a thinned ligament.
In 17 patients, MR imaging showed features of moderate lateral epicondylitis. One patient had a
thinned ligament feature of moderate lateral epicondylitis. In 14 of these patients, the lateral
ulnar collateral ligament was thickened and in the remaining three patients, the ligament was
All eighteen patients with severe lateral epicondylitis showed abnormalities of the lateral ulnar
collateral ligament on MR imaging.
In two of these patients, the lateral ulnar collateral ligament was thickened. In Six patients we
saw a partial tear, and in the remaining ten patients we saw a complete tear of the ligament.

Conclusion. In our study, MR imaging features of lateral epicondylitis were offen associated
with thickening and tear of the lateral ulnar collateral ligament and the frequency and severity of

Diazepam is one of the most widely used sedative hypnotic agents, and many women take
this drug during pregnancy.
The purpose of this study was to investigate the effects of diazepam on the development of
the neuropil of the Purkinje cell layer of the cerebellar cortex.
Twenty female pregnant rats were used in this study. The rats were divided into two groups, the
first group (5 rats) was used as control group and the second group (15 rats) were given 10
mg/kg/day of diazepam orally and sacrificed at 15th, 20th, 25th days of pregnancy. It was difficult
to differentiate between the dendrites and the axonal knobs at 15th day of pregnancy. As age
advanced, the dendrites were swollen with absence of cytoplasmic organelles or contained few
free ribosomes and immature mitochondria. The observed axonal knobs contained ill-defined
synaptic vesicles. Immature axo-dendritic synapses were recognized on the 15th and 20th days of
pregnancy, while on the 25th days of pregnancy symmetrical axo-dendritic synapses were
recognized. From this study, it appears that the exposure to diazepam causes marked changes on
prenatal development of neuropil of the Purkinje cell layer of the cerebellar cortex.

: Recombinant human interferon alpha (rh-IFN-) is used therapeutically in
malignant disorders and chronic hepatitis. The phenotypic effects of this drug at the structural
levels on testicular tissue were hardly ever addressed. Hence, this work was designed in adult
male albino mice to study the phenotypic effects of rh-INF--2b on testicular tissue as well as
assessing its effects on serum testosterone and gonadotropins levels.
Objective: This research was planned to through light on the effects of interferon-alpha-
2b (IFN-alpha-2b) on the hypothalamic-pituitary-testicular (HPT) axis of the adult male albino
Design: Experimental study.
Setting: National Hepatology and Tropical Medicine Research Institute (NHTMRI). The
study was conducted from November (2004) to February (2005).

Materials and methods: Thirty sexually mature male mice were divided into three groups
(10 mice in each group), namely: the control, the experimental and the recovery groups. Mice in
the experimental and recovery groups were administered recombinant human interferon alpha
intraperitoneally at a dose of 3000 U / mouse weekly for 12 weeks in a volume of 1.0-microliter
isotonic normal saline, then animals in the recovery group were left to recover for a further
period of two months. At the end of the experiment, serum concentrations of gonadotropins and
testosterone were measured and then all animals were then sacrificed to study
histopathologically the possible effects of interferon on the testicular tissue.
rh-IFN--2b induced remarkable decline in the serum levels of both follicle
stimulating hormone (FSH) and luteinizing hormone (LH) in mice of the experimental group
compared to the corresponding control and mice of recovery group. At the same time,
testosterone was moderately increased in the experimental group, and then returned to its
normal levels within 2 months after cessation of treatment. Histopathologically, in the
experimental group, there were focal thickening of the basement membrane, degenerative
changes and clumping of the germinal epithelial cells in the center of seminiferous tubules,
partial desquamation of the germinal epithelium from basement membrane, reduction in the
germ cell height, partial arrest of maturation and increased number of Sertoli cells. Increased
number of Leydig's cells and hypervascularity were detected in the interstitial spaces. In the
recovery group, there was lessening of the germ cell hypoplasia manifested by restoration of
spermatogenic cells and accidental disruption in the basement membrane. Most of the
spermatogenic and Sertoli cells restored their polarity, height and maturation.
Conclusion: our results suggest that rh-INF--2b temporally affects the hypothalamic-
pituitary-testicular axis (HPT), both centrally and peripherally (at the testicular level), through
the lessening of FSH, LH, raise of testosterone serum levels and direct phenotypic effect on the
testicular tissue.

Effect of lupine (Lupinus termis) seeds or their water extract
on alloxan diabetic rats

H. A. Hassan and M. M. El-Komy
Zoology Department, Faculty of Sciences, Mansoura University, Mansoura, Egypt.

Diabetes mellitus represents a major public health problem. Much of the increased
mortality and morbidity seen in diabetic patients is the result of various complications. Free
radicals play an important role in the cause of complications of diabetes mellitus such as
retinopathy, nephropathy, hypertension, arteriosclerosis and ischemic heart diseases. Many
secondary plant metabolites have been shown to possess antioxidant activities, improving the
effects of oxidative stress in diabetic patient. Thus the present study tries to evaluate the role of
different preparations from Lupinus termis as a hypoglycemic agent. Alloxan diabetic rats were
orally treated with either 5 ml/Kg b.wt/day aqueous lupine seeds extract or 20% w/w in diet
edible boiled lupine seeds powder or 20% w/w dry lupine seeds powder for 30 days. The results
recorded high levels of glucose, total cholesterol, triglycerides and LDL-cholesterol as well as
low levels of total protein, HDL-cholesterol, liver glycogen and serum insulin in diabetic rats.
Phospholipids content was increased in the serum but decreased in the liver and pancreas of
diabetic rats. In addition, the results confirmed that the alloxan diabetic rats were subjected to
oxidative stress as indicated by the extent of lipid peroxidation (high malondialdehide levels)
present in the liver and pancreas and significantly alter activities of some scavenging enzymes
(low glutathione reductase, glucose-6-phosphate dehydrogenase, superoxide dismutase and
catalase). On the other hand, after administration of any one of the used preparations of lupine
seeds, the diabetic rats revealed an improvement on various metabolic abnormalities as well as
oxidative stress recorded with diabetes but the best improvement occurred in the animal group
treated with dry seeds powder. These results give a good evidence for the amelioration effect of
lupine against the alloxan diabetic effects.

The increased exposure to radiation in medicine or industries increases the hazards of
radiation on various organs of the human body.
The aim of this work was to evaluate the protective effect of anti oxidant (vitamin C)
against the effect of radiation on rat testes.
Thirty adult albino rats were divided into three groups, each contained ten rats .The first
group (G.1) was exposed to 415 r (G.1') or 622 r (G.1") using x-ray source for one minute per
day for one week. The second group (G.2) was exposed to 415 r (G.2') or 622 r (G.2") using x-
ray source for one minute per day for one week, in addition to vitamin C equivalent to 86.9
mg./liter orally for the two sub groups for the same period . The third group (G.3) was a control
The examined testes of G.1 showed damaged germinal epithelium with remaining some
layers of spermatogonia. There was no affection of spermatocytes, mature sperms, Sertoli cells
and Leydig cells, the lumen contained little sperms and debris of germ cells (G.1') .While for
(G.1") there was marked damage of the seminiferous tubules with irregular outline, destruction
of spermatogonia, spermatocytes and spermatids with pyknotic type of nuclear degeneration and
the lumen was devoid of mature sperms. The examined testes of the (G.2) showed evidence of

Background: Fructus Schizandrae Sinensis bail, a traditional Chinese medicine, has been
shown to lower the elevated serum level of liver enzymes of patients suffering from chronic
active hepatitis. A synthetic derivative compound of Schisandrian, Dimethyl Diphenyl
Bicarboxylate (DDB) is now used widely in clinical fields as a hepatoprotective drug. Thus it is
important to know whether DDB has a beneficial effect on damaged liver or not.

To evaluate the protective effect of DDB on induced liver tissue injury in rats.

Design: Experimental study.

: National Hepatology and Tropical Medicine Research Institute. The study was
conducted from October (2004) to February (2005).

Materials and methods:
120 male albino rats aged 6-8 weeks, weight 150-200g were grouped
in six groups, 20 rats per group. Group 1 received food and water only, group 2 received food,
water and DDB intragastric 6mg/kg daily for 12 weeks, group 3 received 20% ethanol instead of
water, group 4 received 20% ethanol instead of water plus DDB, group 5 received
thioacetamide (TAA) in a dose of 200mg/kg body weight intraperitoneal injection, group 6
received thioacetamide plus DDB at the same dose of the above group. At the end of the trial,
blood samples were taken from all groups for biochemical analysis. Liver tissue excised from
each rat was fixed in 10% neutral formalin, embedded in paraffin, and stained with Hematoxylin
and Eosin, as well as Masson's trichome stain, for evaluation of hepatic injury and/or fibrosis.

Statistical elevation of serum hepatic enzymes was noticed in rats received alcohol,
Thioacetamide and alcohol + DDB (groups III, V and IV respectively) compared to the
corresponding control (P= 0.000). On the other hand, administration of DDB to TAA treated
group (group VI) induced significant improvement of liver function tests compared to other
groups (P= 0.000). Histopathologically, the control livers showed normal lobular architecture
without any pathological changes. Liver sections of animals administered alcohol, TAA
respectively showed chronic inflammatory reaction, fat accumulation, hepatic parenchymal
necrosis and/or hepatic fibrosis. Administration of DDB resulted in improvement of the
pathological changes induced by TAA (group VI), but not that induced by alcohol (group IV).

Our results revealed that DDB has antitoxic effect against TAA and ameliorates
the dangerous effect on the liver parenchyma, while it has no beneficial effect on alcoholic liver

Effect Of Fractionated And Single Doses Gamma Irradiation
On Certain Mammalian Organs

*Radiation Biology and ** Radiation Health Research Departments, National Centre
for Radiation Research and Technology, Cairo, Egypt.

The present work aims to study the effect of fractionated and single dose whole body
gamma irradiation on the liver, spleen and intestine of albino rats.
30 Male albino rats (100-120g) were used as experimental animals, they were divided
into three groups: The first group consists of 10 rats served as control group (non irradiated),
the second group (10 rats) were subjected to a single dose of irradiation (5Gy) and the third
group (10 rats) were subjected to gamma of irradiation (5Gy) delivered at 5 successive
exposures daily.
Histological results showed serious histopathological disorders in the liver, spleen and
intestine after exposure to the single dose of gamma irradiation (5Gy), manifested by
inflammation and infiltration with mononuclear cells, haemorrhage, dilatation, congestion and
widening of blood vessels and necrosis of cells with pyknotic nuclei.
Exposure of rats to fractionated doses of whole body gamma irradiation (1Gy) up to
5Gy resulted in less severe histopathological disorders in liver, spleen and small intestine
This indicates the beneficial use of fractionated doses in planning for radiotherapy in

The Possible Ameliorative Effect Of Dimethyl Dicarboxylate
Biphenyl (DDB) Against Mancozeb­Induced Testicular Toxicity
In Rats

Manar Effat Selim
Zoology Department, Faculty of Science, Ain Shams University


Mancozeb, an organocarbamate fungicide, has been widely used for several
decades. Despite the wide scope of exposure to this compound, up till now, there is a
scarcity in published studies on the toxicity of mancozeb and its impacts on cell structure
and functions. Thus the present study was designed to investigate the possible
counteracting effect of dimethyl dicarboxylate biphenyl (DDB) in reducing the hazards
caused by mancozeb in the testies. The effects of mancozeb given separately or
simultaneously with DDB on rat testis were studied histologically and ultra structurally.
Twenty-one male albino rats were divided into three groups, 7 rats each. The first group
was given orally 0.5 ml of distilled water and served as control. Animals of the second
group were given mancozeb orally at a dose level of 500 mg/kg b.wt for 15 consecutive
days. Animals of the third group received the same dose of mancozeb as in the second
group and simultaneously given DDB (50 mg/kg b.wt) through the same route of
administration. Mancozeb treatment induced cellular damage manifested as exfoliation
and destruction of the spermatogenic lineage. Destructed spermatids and Leydig cells
were also pronounced. The ultra structural observations revealed marked cytoplasmic
vacuolation in Sertoli cells and spermatogonia. Some cytoplasmic organelles of the
spermatogonia and primary spermatocytes were degenerated. Moreover, destructed
spermatids were pronounced in most of the seminiferous tubules. The interstitial cells
appeared devoid of lipid droplets and the mitochondria appeared with disintegrated
Administration of DDB simultaneously with mancozeb ameliorated most of the
testicular tissue damage. This was reflected as restoration of the normal appearance of the
spermatogenic lineage. Numerous spermatids were demonstrated in the lumens of the
seminiferous tubules, most of them showed similar structure to those of the control group.
In conclusion, it is possible to suggest that DDB might have ameliorated and amended the
abnormalities caused by mancozeb.

This study was conducted to compare between the possible effects of rosiglitazone "A new
oral antidiabetic drug with selective PPAR-gamma agonistic effect" in a dose of 0.03 mg/kg
BW and gliclazide " An oral antidiabetic sulphonylurea" in a dose of 10 mg/kg BW either used
alone or in combination, for 6 weeks on the liver, serum glucose and lipid profile in
streptozotocin diabetic rats.
Thirty rats were randomized into 5 groups (n=6). Group I; the control group was given
saline orally daily for 6 weeks. Group II; the streptozotocin induced diabetic group. Group III
received rosiglitazone, while group IV received gliclazide and group V received both drugs.
The results of the present study revealed that streptozotocin significantly (P< 0.05) elevated
serum glucose, cholesterol and triglycerides in rats compared to the controls. The insulin
sensitizer "rosiglitazone" either alone or combined with gliclazide decreased serum glucose
significantly (P< 0.05) compared to the diabetic group. Gliclazide alone also had the same
effect. Rosiglitazone alone decreased serum cholesterol and AST and in combination with
gliclazide decreased serum ALT significantly (P< 0.05) compared to the diabetic group.
For histopathological study, liver tissue was prepared for both histological (H&E, PAS &
Masson's trichrome) and immunohistochemical (alpha 1 antitrypsin expression) techniques.
Both qualitative and quantitative analysis was done to assess the degree of hepatic damage.
According to certain criteria, H&E stained sections were quantitatively examined to assess the
degree of hepatocyte affection, beside other quantitative measurements (optical density & color
area percentage) using the image analyser. Obtained results revealed that streptozotocin caused
severe affection in 6% of hepatocytes, mild affection in 2% and moderate affection in 41%. The
drug also resulted in significant increase in PAS stained glycogen granules in hepatocytes as
well as collagen in portal tracts. Immunostaining of alpha 1 antitrypsin revealed increased
expression in the lining of blood sinusoids including Kupffer cell cytoplasm and in the area
around the central vein. Groups III, IV and V which were under the effect of rosiglitazone,
gliclazide or both respectively, showed hepatocyte damage similar to that of diabetic control
group; however the degree of that damage was only statistically significantly increased in case
of group III.
When compared to diabetic control group, these groups (III, IV and V) showed no
significant difference in both optical density of PAS positive reaction or mean color area
percentage of collagen; however the mean optical density of immunostaining decreased
This indicated that rosiglitazone alone or when used concomitantly with gliclazide, in
streptozotocin-induced diabetic rats resulted in improvement of their metabolic control, yet the
potential of hepatotoxicity was still to be considered.

Children usually eat and drink food containing both food preservatives, as sodium nitrite
and food colourants, as sunset yellow (S.S.Y) at the same time. The mixture of the two agents at
the limited dose of each was found to be lethal. 1/10th of this dose was used daily for 30 days.
Animals were divided into three groups. The first served as a control, while the second was
orally administered a mixture of sodium nitrite (NaNO3) and S.S.Y. The third received garlic in
addition to the above mixture. Half of the animals from each group were decapitated after 30
days of treatment, while the other half was left for another 15 days for recovery. Investigation of
the mixture of sod.nitrite and S.S.Y significantly decreases protein and albumin. Significant
increases were observed in cholesterol, gamma-glutamyltranspeptidase (GGT), alkaline
phosphatase (AP), lactate dehydrogenase (LDH) and creatine phosphokinase (CPK). No change
was observed for Total protein, Triglyceride, aspartate aminotransferase (AST), alanine
aminotransferase(ALT) and acid phosphatase (AcP) recorded.
A complete recovery from the abnormalities of most biochemical parameters was
observed after the recovery period or when garlic was administered. This draws attention to the
dangers of interactions of such preservatives and colourants. The present study showed that
even the permitted doses of colourants and food preservatives may be harmful. And illustrate
that usage of garlic may ameliorate some of the expected hazards of food additions.

Recently, it is recorded that electromagnetic field (E.M.F) is considered dramatically as
one of the most dangerous environmental pollutant especially among the developing
industrialization societies. The present study aimed to investigate the effect of continuous daily
exposure to alternating magnetic field (AC/E.M.F). Adult male mice were classified into three
groups. The first group was kept as control. The second group received (50 HZ/AC of 2mT)
daily for 20 days. The third group received the same dose and kept for another one month (post
treatment) without exposure. Histological and Ultrastuctural studies were carried out on liver
tissue using light and electron microscopes.
The microscopic examination of the liver specimen of the second group revealed
degenerated liver tissue when compared to control group, shrinking rough endoplasmic
reticulum, swollen degenerated mitochondria and pyknotic nuclei. Examination of the liver
specimens of the third group showed more severe degeneration in comparison with the second
group and no sign of recovery was observed.

Aluminium (Al) is one of the most abundant and important elements in the environment. In
recent years, the production of this metal and its toxicity increased with its discharge into the
environment. This study was designed to evaluate the effect of Al intake toxicity in liver and kidney
tissues of albino rats and the role of zinc as a protective agent against Al toxicity.
Fourty five male albino rats were divided into equal three groups. The first group of animals
was considered as control. The animals in the second group were given (50mg/kg/day) of Al
sulphate orally using gastric tube for 45 day. Third group were given Al sulphate (50mg/kg/day)
followed by zinc sulphate (50mg/kg/day) orally as well as samples of liver and kidney tissues were
obtained after 15, 30, 45 days of last doses respectively. Paraffin sections (5m) were prepared for
histological study stained with Haematoxylin & Eosin.
The obtained histological results of the histological study of the second group showed that
there were congested blood sinusoids and swelling of some hepatocytes within cytoplasm in which
there were vacuoles, fragmented nuclei with some cellular infiltration. Kidney tissue showed
shrinkage of some glomeruli and distortion of the tubular epithelial cells. Results in the third group,
where zinc sulphate was added, showed amelioration and improvement in both liver and kidney

Combined topical and intracameral anesthesia proved to be an alternative to peribulbar
and retrobulbar anesthesia in cataract surgery especially in phacoemulsification approach.. So,
in the present work the effect of intracameral injection of different concentrations of lidocaine
on the structure of rabbit's cornea was studied using the freez-fracture technique and the
scanning electron microscope . Fourteen baladi rabbits of both sexes weighing 2-3 kg.were
used and divided into two groups according to the concentration of lidocaine .One eye of the
animals of the first group was injected with 0.2 ml. of 0.5% lidocaine into the anterior chamber
and the other eye with balanced salt solution (BSS)and served as control . In the second group ,
one eye was injected with 0.2 ml. of 2% lidocaine and the other eye with (BSS) .In both groups
the duration of injection was 10 minutes. Parts of the cornea were prepared for scanning
electron microscopic examination. The control specimens showed polygonal epithelial cells
with surface microvilli , microplicae and craters. The craters had raised edges with fenestrations
and / or microvilli on their floor. Bowman's membrane was acellular homogenous layer.The
stromal lamellae were arranged in zip pattern. The keratocytes were spindle-shaped with
irregular surface . Descemet's membrane appeared to be splitted. The endothelium was seen as
polygonal cells with raised edges and surface micrvilli. With the use of 0.5% lidocaine the
endothelial cells became oedematous. On the other hand, with the use of 2% lidocaine there was
excessive blebs, bullae and marked oedema of the endothelium with sloughing of some cells.
So, the injection of high concentration of lidocaine into the anterior chamber during cataract
operation is a potential risk for endothelial injury that may lead to loss of corneal
transparency.However using the low concentration of lidocaine appeared to be safe with no
adverse effects .
