Abstract

Background : Atopic dermatitis ( AD) is a chronic or chronically relapsing inflammatory
skin disease with a prevalence ranging from 10% to 20% in children of developed countries.
Skin-infiltrating leukocytes play a pivotal role in the initiation and amplification of atopic skin
inflammation. The cytokines produced by T helper- 2 ( Th2) cells are crucial factors in the
induction and maintenance of the disease .
Aim: to study the percentage of expression and mean fluorescence intensity( MFI) of the
activation marker CD38 and the chemokine receptor CXCR3 on peripheral blood CD3+
lymphocytes in children with atopic dermatitis . Also total serum IgE and absolute differential
count were evaluated .This might be targets for therapy in disease .
Methods: This study was conducted on thirty cases of AD children. Their age range was
3- 10 years. Also non atopic fifteen children age and sex matched with disease group were
included as a control group. The percentage of expression of the CD38 , CXCR3 and MFI
were analyzed by flow- cytometry on peripheral blood CD3+ T lymphocytes . Also total serum
IgE levels was measured by immunonephelometry . The absolute eosinophil , absolute
lymphocytes, absolute neutrophil count were evaluated .
Results: The mean percentage of CD38 expression on CD3 + lymphocytes and MFI were
70.5% and 5.8 respectively in AD children compared with 17.8 % and 5.1 in non ­atopic
children healthy control ( p < 0.01 and p > 0.05 respectively ) . The mean percentage of
CXCR3 expression on CD3+ T lymphocytes and MFI in AD children were 17.9 % and 2.9
respectively compared with 67.93 %and 3.3 in healthy controls (p < 0.01 and p > 0.05
respectively ). The mean of the total serum IgE in the patient group was 199.3 IU/ml compared
with 62.27 IU/ml in non-atopic children (p < 0.01).
Conclusion : These results suggest that there is a relation between atopic conditions and
an increase in peripheral blood T lymphocyte expressing CD38% and decrease expression of
CXCR3%.The presence of high expression of CD38 in atopic patients seems to confirm the role
of this molecule as an activation marker useful for evaluation of Th2 immune response .
whereas CXCR3-expression on CD3+ lymphocytes decreased in AD than normal control as the
chemokine receptor profile determine the migratory patterns of leukocytes . These results may
suggest the dysbalance between Th1/ Th2 in AD patients .

Abstract

Aim of the work :The present study aimed to investigate the possible effect of the
electromagnetic field (EMF) on the skeletal muscles and skin of fetuses maternally exposed to
EMF.
Material and Methods: Pregnant Swiss albino rats were exposed to EMF(50Hz&2mT)
8hours day after day 10 days before pregnancy and 20 days, day after day through pregnancy.
Results: Exposure of pregnant rats to the electromagnetic field (EMF)of 50 Hz and
2millitesla(2mT), showed many dystrophic changes in the skeletal muscles and skin of their
fetuses .Highly thickened and disturbed epidermal layer was noted with decreased number of
hair follicles. Some hemorrhagic areas were noted in the dermis. Highly disturbed skeletal
muscle fibers were noted with many deleterious changes in the nuclei of their cells. Altered
protein content, polysaccharides and collagen bundles were observed in the muscle fibers and
skin of fetuses taken from exposed pregnant rats to EMF.
Conclusion
: It is clear that EMF has a deleterious effect on skin and skeletal muscles of
fetuses maternally exposed to EMF.

University, Cairo, Egypt

Abstract

Background :Coffee is one of the most popular beverages in the world. The present work
was designed to study the effect of dietary coffee and zinc on serum lipid profile , zinc and
copper in serum and liver
Material and Methods : Forty two adult male albino rats were divided into six groups
and fed on different diets ad libitum for 7 weeks as follows: Group (1) fed on standard basal
diet , group (2) fed on standard diet supplemented with zinc chloride (ZnCl2) at dose of (20
mg/kg diet) , groups ( 3and 4 ) fed on standard diet supplemented with boiled coffee at two
doses ( 15 g and 30 g / kg diet ) respectively , groups (5 and 6 ) fed on the previous two diets
respectively but in combination with ZnCl2 (20 mg/kg diet) . At the end of the experiment
some biochemical analyses were measured in serum and liver .
Results: The results showed significant elevation of serum total lipids (TL), total
cholesterol (TC), triacylglycerols (TG), low density lipoprotein-cholesterol (LDL-c), while a
significant decrease of high density lipoprotein-cholesterol (HDL-c) in rats fed diet
supplemented with low or high dose of coffee. When rats fed zinc with low or high dose of
coffee, improvement in lipid parameters were observed. Also serum lipid peroxides as
malondialdehyde (MDA) showed significant increase while blood glutathione (GSH) showed
significant decrease in rats fed zinc, coffee (low or high dose) or zinc plus coffee (low or high
dose).
Diet supplemented with zinc caused significant increase in serum and liver zinc , on the
other hand significant decrease in serum and liver copper were recorded. Moreover, the high
dose of coffee led to significant decrease in liver zinc. On feeding zinc and coffee together
resulted in significant elevation of serum and liver zinc levels, but serum and liver copper
decreased significantly.
Conclusion: So zinc may be able to overcome the adverse effects of coffee also
administration of zinc plus coffee could decrease lipid peroxidation.

Relationship between polymorphisms in thrombophilic genes and preeclampsia In Egyptian population The Egyptian Journal of Hospital Medicine (2008) Vol., 33: 503­ 509

Relationship between polymorphisms in thrombophilic genes and
preeclampsia In Egyptian population

Clinical Pathology*, Obstet & Gynecol**,Alazhar University

Abstract


Background: Hypertensive disorders are a major cause of maternal and fetal death
especially in developing nations. Preeclampsia has a familial component suggesting that one or
more common alleles may act as susceptibility genes. Some families may have "private"
predisposing mutations. Preeclampsia and its association with thrombophilia remain
controversial, due to inconsistent results in different studies.
Aim
: The aim of this study was to evaluate the relationship between thrombophilic genes
mutations and preeclampsia in pregnant women in our region.
Methods:
We compared 15 consecutive women with preeclampsia with 10 normal
pregnant women. All women were tested for mutations of factor V lieden , Factor II
(prothrombin gene ) , Factor XIII, B fibrinogen , plasminogen activator inhibitor -1 4G/5G
(PAI-1 4G/5G ), methylenetetrahydrofolate reductase (MTHR) , angiotensin ­converting
enzyme (ACE) I/D , apolipoproteins (APO E and APO B ) genes. This study was based on
reverse ­ hybridization technique using cardiovascular disease strip (CVD ) assay .
Results: PAI-1 4G/5G polymorphism was highly significantly increased in patient group
as compared to control group (60% versus 0% , p= 0.000) . No significant differences were
noticed as regards other thrombophilic genes in control and patient groups.
Conclusion We suggest that the pattern of PAI 4G/5G polymorphism might represent a useful
marker of increased risk of preeclampsia in our region. Also our findings suggest that women
with severe complications of pregnancy should be tested for markers of thrombophilia.

Abstract

Objective: The present study is carried out to investigate the protective effect and
antioxidant activity of soybean and thyme on iron deficiency anemia.
Material and Methods: Thirty five male albino rats were divided into five groups
(7rats each). The first group fed on basal diet, iron sufficient (35 mg Fe / kg), and served as
control. Rats of other groups (second - fifth) were induced anemic by placing them on diet
containing 3mg Fe / kg for 21 days, then divided to four dietary groups. The second group
(anemic) stayed on basal diet with Fe-deficiency. The third group fed on basal diet with
sufficient iron in the form of ferrous sulphate. The fourth group fed modified basal diet free
from iron and supplemented with soybean. The fifth group fed basal diet free from iron and
supplemented with thyme. All three iron sources provide 35 mg iron/kg diet. At the end of
experiment (49 days), rats were anesthetized, whole blood was used for determination of
hemoglobin (Hb), hematocrit (HCt) and reduced glutathione (GSH) levels. Serum was used for
determination of iron and lipid profile as well as lipid peroxidation as malondialdehyde (MDA).
The liver was used for determination of iron and copper concentrations.
Results: The present results indicated that Fe-deficiency caused many adverse effects
reflected the significant decrease of Hb, HCt, serum iron, liver iron, GSH and high density
lipoprotein-cholesterol (HDL-C). Fe-deficiency also caused significant increase in total iron
binding capacity (TIBC), liver copper, MDA, triacylglycerols (TG) and total cholesterol (TC).
In contrary, administration of ferrous sulphate (FeSO4), soybean or thyme induced a significant
increase of serum and liver iron profile.
Conclusion: Soybean and thyme could able to provide iron to correct dietary iron-

Abstract
Introduction:
Ketorolac tromethamine is a potent injectable non-steroidal anti-
inflammatory drug (NSAID). Ketorolac provides successful analgesia after intrathecal or
epidural injection. It is frequently used to manage post-operative pain, cancer pain, and
arthritis either intrathecally, or intramuscular. However, its long term administration could
induce renal toxicity and/or gastro-intestinal ulceration.
Aim of the study: The aim of this study was to assess the analgesic potency of ketorolac
after intrathecal injection. Also, we aimed to study the histological effect of ketorolac on the
spinal cord and the duodenum after treatment in an animal model.
Methods: 40 adult male albino rats, weighing 250-350 gm, were used and divided into 4
groups, 10 rats each. Group S (control) received 10l normal saline intrathecally, group K50
received 50g ketorolac intrathecally, group K50 + omeprazole (proton pump inhibitor)
received 50g ketorolac intrathecally plus 0.2 mg omeprazole orally, and finally, group K100
received 100g ketorolac intrathecally. All animals were treated for four successive days.
Result: The rat tail flick latency was longer in K50, K50 + omeprazole, and K100 groups
when compared to normal control (P = 0.002). Also, the hind-paw withdrawal latency was
longer in treated groups when compared to those of the control group (P = 0.0001). Moreover,
K50 group showed decreased phase II response by 61%, K50 + omeprazole group showed
decreased phase II by 62%, while K100 group showed decreased it by 76%.
Histological examination revealed no changes in the spinal cord of all treated animals. Also,
examination of the duodenum showed normal duodenal mucosa in group K50 and those of
group K50 + omeprazole. On the other hand, cellular infiltration as well as destruction of the
mucous acini have been noticed in the duodenum of K100 group.
Conclusion: Ketorolac could be a good alternative drug used intrathecally to manage pain.

Abstract

Background: Urinary bladder cancer is one of the major health problem all over
the world. Cystoscopy remains the gold standard for identifying bladder cancer but it
is invasive and expensive, therefore, a simple, non invasive test for detecting bladder
cancer would be helpful. Several biomarkers for bladder cancer have been used, but no
single marker has been accurate and conclusive.
Aim: The current study aimed to measure telomerase enzyme in urine as a useful
non invasive marker for detection of bladder cancer.
Methods : Forty eight patients ( 39 males and 9 females) were included, They are
complaining of urinary symptoms and undergo cystoscopy with biopsy of bladder lesions and
histopathological examination. They were divided into groups: Group I: 16 patients ( 11 males
and 5 females) have benign urologic conditions. Group II: 32 patients (28 males and 4 females)
have proven bladder cancer patients underwent transurethral resection of bladder tumor or
cystoscopy with biopsy of bladder lesions. Also, 15 apparently healthy volunteers with
matched age and sex with patients were served as a control group. All subjects were submitted
to laboratory estimation of the following in urine: urinary creatinine, urine cytology,
telomerase enzyme in urine by telomerase PCR and complete urine examination.
Results : The results of this study revealed that a highly significant increase in the
frequency of cytolological positive cases for tumor cells in malignant group than each of
benign group and healthy subjects, while no significant difference was detected between
benign group and healthy subjects. The frequency of telomerase in urine was significantly
higher in malignant group than each of benign group and healthy subjects, while no significant
difference was detected between benign group and healthy subjects. The telomerase activity
has sensitivity of 90.6% for diagnosis of cancer bladder with 93.7% for specificity and PPV
was 96.6%, NPV was 83.3% and diagnostic accuracy of 91.6%. While, urine cytology gives a
sensitivity of 68.8%, specificity of 87.5%, PPV of 91.6%, NPV 58.3% and diagnostic
accuracy of 75%. When combined tests were used the sensitivity raised to 96,8%, and
specificity reached to 100%, PPV was 96.6%, NPV was 94.1% and diagnostic accuracy
increased to 97.9%.
Conclusion: the urinary assay of telomerase could be used as non invasive test to
identify the bladder cancer patients and distinguish them from normal subjects and
patients with benign tumor of urinary bladder. The low cost of this test may help to be
implicated as non invasive screening of bladder cancer.

Effcts of the herbicide gallant and mercury on liver function of Tilapia zilIi

Abdel-Salam Mohamed Ibraik Ohaida
Zoology Department, Faculty of Science, 7th of October University, Misurata, Libya.


Abstract


Background: Herbicides are highly toxic for both human and animal health. The
increased application of herbicides in agriculture during the last decades has resulted in the
contamination of both soil and water. Also do heavy metals, which represent one of the most
important group of pollutants produced as a result of many industrial activities which can find
their way easily to the normal aquatic environments, disturbing and damaging the existing
organisms.
Material and Methods: Fishes of the species Tilapia zillii were exposed to sublethal
concentration of herbicide Gallant (haloxyfop-ethopxy ethanol ester) (3 mg/L), mercury as
mercuric chloride (6 mg/L) and a combined dose of herbicide (1.5 mg/L) and mercury (3 mg/L)
for 96 hrs., in aquaria under controlled laboratory conditions. A comparative physiological study
was carried out to test the toxicological effects of these pollutants on glutamic pyruvic
transaminase (GPT), glutamic oxaloacetic transaminase (GOT) activities & hepatosomatic index
of liver.
Results: A progressive decrease in enzyme activity as well as total protein content of liver
were observed, while hepatosomatic index showed a slight insignificant increase.

Abstract:

Background:
Opuntia dillenii Haw fruit is used in folk medicine as an antidiabetic agent.
The aim of this study was to evaluate the possible curative role of O. dillenii fruit juice using the
streptozotocin (STZ)-induced diabetic rats. The nutritive value of the edible portion of the fruit
was also assessed.
Results: The results showed that O. dillenii fruit is a rich source of fiber, carbohydrates,
vitamins B1, B2 and C, in addition to the minerals, Fe, Zn, Cu, Cr, Mn, Ca, and Mg. Biological
results showed that intraperitoneal injection with STZ caused highly significant reduction in
body weight gain% , highly significant elevation in blood glucose concentration accompanied
by significant reduction in liver glycogen cotent as compared with control group. Diabetic rats
also revealed significant elevation in lipid peroxide (MDA) level, highly significant elevation in
total cholesterol (TC), triacylglycerols (TAG), low-density lipoprotein cholesterol (LDL-C) and
very low-density lipoprotein cholesterol (VLDL-C) concurrent with highly significant reduction
in high-density lipoprotein cholesterol (HDL-C) as compared with control group. Oral
administration of O. dillenii juice had no effect on normal rats. Meanwhile, oral administration
of O. dillenii juice to diabetic rats induced siginficant improvement in body weight gain % and
lipid profile, it reduced significantly blood glucose and MDA levels as compared with non
treated diabetic group. Histopathological investigation of the pancreatic tissue of STZ-diabetic
rats represented the presence of necrosis, edema and congested blood vessels in the islets of
Langerhans cells. O. dillenii fruit juice treatment overcome the previous changes, the majority
of the cells tend to be normal.The improvement in the cells of Langerhans islets may explain the
antidiabetic effect of the fruit juice under study. It also may improve the insulin receptors of -
cells.
Conclusion: It could be concluded that O. dillenii fruit juice had a potent hypoglycemic
activity, this effect may be attributed to its antioxidant activity and its high content of chromium
which was proved in this study. Therefore, it could be recommended that O. dillenii should be
ingested as fresh fruit to diabetic and hypercholesterolemic patients beside the usual therapy.

Abstract

Background:The current investigation was carried out to study the effect of orally
administration of diazinon insecticide on some biochemical blood indices on male albino rats.
Material and methods: The organophosphorus insecticide , diazinon was orally
administrated at a dose
(100mg/kg body weight=1/3LD50) , daily for 10 days (short ­term) and 20 days (long ­term) to
adult male albino rats .
Results: The results revealed the following:
1- Diazinon led to an increase in rat blood serum glucose& T3 (short and long ­term);
AST,ALT, and T4 (long-term).
2- Diazinon reduced the serum content of total cholesterol and protein in short­term

Tumor necrosis factor- (TNF- ) in glutathione (GSH)-depleted rats. A
possible link to impaired glucose metabolism

Sohair A. Moustafa
Department of Zoology, Faculty of Science, Suez Canal University, Ismailia, Egypt.


Abstract

Rats
: treated with the glutathione depleting agent, allyl alcohol (AlAl) (1 mmol/kg) was
found to induce a marked increase in serum TNF- 45 minutes post treatment. This increase is
suggested to play a critical role in the development of impaired glucose metabolism and glucose
intolerance in AlAl-treated rats. Impaired glucose metabolism was evidenced by the significant
increase in serum creatinine, urea and blood urea nitrogen accounting for accelerated glycolysis
and breakdown of creatinine phosphate. These are the metabolic consequences of the activation
of a back up system for the generation of ATP when the primary energy forming pathway is
impaired. Meanwhile, the present data show a significant decrease in the serum levels of
triglycerides and cholesterol in AlAl-treated rats that was accompanied with a concomitant
increase in their liver levels indicating the development of fatty livers in these rats. Due to the
strong link between TNF- and the GSH status and to the well established role of TNF- in
causing insulin resistance, which is potentiated by fat accumulation in different tissues, it is
concluded that the combination of TNF- overproduction, GSH depletion and lipid
accumulation in the liver caused by AlAl treatment, cooperate making cells more sensitive to
AlAl poisoning, therefore, imposing a potent negative impact on glucose metabolism. Added to
the deleterious effects of TNF- , enhanced lipid peroxidation observed in AlAl- treated rats
suggests possible alterations in the rates of glucose transport and metabolism which may further
contribute to AlAl-induced impairment in glucose metabolism.
Conclusion: Finally, the selective effect of TNF- in inhibiting insulin secretion give an
additional support to its hypothesized role in initiating glucose intolerance in GSH-depleted rats.

Abstract

Background: This study was conducted to test the utility of polymerase chain reaction
(PCR) assay to detect recent infections with Toxoplasma in pregnant women. T.gondii DNA
was detected by using B1 gene as a target for amplification which is highly specific for T.gondii
and is well conserved among all of the tested strains.
Results: This study revealed the following findings:(1) PCR was positive in 63 subjects,
including 58 high risk cases (77.3%) and 5 of controls (12.5%). (2) 17 high risk cases (24.6%)
had false positive IgM and 5 of controls (12.5%) had false negative result for IgM. (3) 17 high
risk cases (32.7%) had false positive IgG and 5 of controls (12.5%) had false negative IgG. (4)
No significant association between eating raw meat or contact with cats and positive ELISA for
PCR but there is highly significant association between women with contact with soil and
positive PCR. (5) No significant relation between residency and either ELISA or PCR. (6)
Significant negative correlation between the age of the studied women and positivity of PCR.
Conclusion
: this study highlights the need for a confirmatory test to detect primary acute
toxoplasmosis in pregnant women. It demonstrates the possibility of defining and selecting the
high-risk cases for mother-to-child transmission of infection by combining specific serology and
PCR tests to formulate a specific approach

Abstract

Aim of the work
: The present study aimed to compare between the anatomy, histology
and histochemistry of two species belonging to two different families namely Muridae and
Dipodidae. Muridae is the largest family of rodents in the world; it is represented in this work
by fat sand rat Psammomys obesus. Four-toed jerboa Allactaga tetradactyla represents the other
family, Dipodidae. Psammomys obesus lives in coastal presaharan region; the preferred habitat
is saline marshes and wadis where halophytic plants were abundant. However, Allactaga
tetradactyla
, inhabites the salt marshes and clay desert areas of coastal plains.
Material and methods: The investigated animals were collected from desert, weighed and
transferred alive to the laboratory in separate cages then anaesthetized with ether, after which
they were carefully dissected, organs are taken out and prepared for the histological and
histochemical studies.
The nucleocytoplasmic index of liver cells was calculated, kidney weighed and the relative
thickness of cortex, outer and inner medulla was measured and total glomerular number was
recorded.
Results: The liver, as in mammalian species, is consists of five separate lobes. The mitotic
index of Psammomys obesus is smaller than that found in Allactaga tetradactyla. This may be
due to the increased activity of Allactaga tetradactyla.
In the kidney, the cortex is classified into three regions namely superficial, midcortical and
juxtamedullary zones. Both number and diameter of glomeruli, glomerular volume and relative
glomerular blood volume is greater in Psammomys obesus than that in Allactaga tetradactyla.
Conclusion: These observations indicate the ability of Psammomys obesus to produce highly
concentrated urine than that of Allactaga tetradactyla.

Abstract

Background:
The use of pesticides has been increased considerably nowadays compared
to the past. The hazards of using such chemical compounds have been accentuated by the sharp
rise of their use in agriculture, industry, by householders and governments. Exposure to
organophosphorus insecticides (OPI) in agriculture is one of the occupational hazards.
Fenitrothion is one of the most important OPI. The major object of the present study was to
evaluated the toxicological (biochemical, mutagenic and histopathological) effects of tested
insecticide "fenitrothion" alone or combined to vitamin E as an antioxidant agent to decrease
their toxic effect.
Material and Method
male albino rats were tested orally for 30 days, three doses of
fenitrothion were used in absence and presence of vitamin E (1/20, 1/40 and 1/80 LD50).
Results the obtained data showed marked changes in biochemical parameter, highly
inhibition of AchE activity; highly significant increase in the frequency of micronucleus
(PCEM) in rat bone marrow cells at all doses of fenitrothion alone or combined to vitamin
compared to control group. Also, the histopathological examination of liver and kidney tissues
revealed high alternation in these tissues corresponding to biochemical changes.
Conclusion
From these results we concluded that fenitrothion exert biochemical,
mutagenic and histopathological effects in white rats. In addition, vitamin E has mild role in
alleviating these toxicological effects.

**Department of Zoology, Faculty of Science, AL-Azhar University (Assiut)

Abstract

Background
: Diabetes mellitus is the most common endocrine metabolic disorder of
childhood and adolescence with important consequences for physical and emotional
development.
Aim of the study: This study was designed to detect the effect of diet therapy (through
nutrition education program) on lipid profile and blood glucose level in diabetic children.
Subjects and Methods: The study was carried on 45 diabetic children aged between 8-15
years old at diabetic nutrition clinic of nutrition institute in Cairo from 2003-2005. Children
included in the study were divided into two groups: insulin dependent dyslipidemic group
(IDDM) (diet control/ group) and insulin dependent non dyslipidemic (control group). All were
subjected to full dietetic history by the 24 hour recall for 3 days, thorough clinical examination,
they were evaluated for plasma lipids, lipoproteins, fasting blood glucose (FBG) and glycated
hemoglobin (HbA1c) levels. The dyslipidemic were measured after three months for the
previously measured parameters. The nutrition education process was performed and continued
on weekly intervals for three months.
Results: There was significant decrease in serum cholesterol and triglyceride levels in the study
group after the program, and insignificant increase in serum HDL and decrease in serum LDL.
Also, there was insignificant decrease in FBG but there was statistically significant decrease in
HbA1 after the program. These changes occurred in parallel with increases in intakes of protein
and total calories with adequate carbohydrate and sometimes a reduction in intakes of total fat.
Conclusion: Nutrition therapy for children with IDDM is essential to improve measures of
glycemic control and lipoprotein mediated risk for dyslipidemia. More innovative approaches to
achieve lifestyle changes are required to meet current recommendations which are likely to
produce greater beneficial changes than those observed in this study.
