Background: Psoriasis is a common inflammatory skin disease characterized by
infiltration of inflammatory cells into the epidermis and altered keratinocyte differentiation.
The aim of the present study was to investigate the role of MMP-9 in the development of
psoriasis by assessing the presence of MMP-9 in lesional skin and in sera of psoriatic patients
with & without psoriatic arthritis, the association of MMP-9 with the activity of the disease, the
relationship between MMP-9 and TNF- production as well as to evaluate the effect of
pioglitazone (one of the agents thiazolidinediones) on TNF-, MMP-9, MMP-2, VEGF and E-
selectin production and in treatment of psoriasis.
Subjects and Methods: Thirty-five psoriatic patients (28 males, 7 females) were included
in this study. They were divided into 2 groups. Group I (PsA) included 15 psoriatic patients,
clinically presenting joint symptoms associated to the cutaneous disease (PsA). Group II (Ps)
included 20 psoriatic patients, clinically presenting cutaneous disease without psoriatic arthritis
(PsA). Each psoriatic patient received pioglitazone 30 mg/day orally for 10 weeks. Lesional
tissue specimens were taken, in the same skin area before and after 10 weeks pioglitazone
treatment. Tissues were kept in short term cultures and production soluble mediators such as
TNF-, MMP-9, MMP-2, VEGF and E-selectin, which include angiogenic molecules associated
to the development of plaque psoriasis, were measured in the culture supernatants by ELISA.
MMP-9 concentrations were also measured in the sera. The cutaneous activity of disease was
evaluated by the Psoriasis Area and Severity Index (PASI).
Results: Clinical and laboratory assessment indicated that all patients had a significant
improvement of the PASI score after 10 weeks of pioglitazone therapy. The clinical
improvement was associated to a significant decrease of TNF-, MMP-9, MMP-2, VEGF& E-
selectin levels (P< 0.05) , spontaneously released by lesional biopsies before and after therapy.
A significant decrease of MMP-9 (P< 0.01) in the sera, associated to the clinical improvement
was also found. In addition, significant positive correlations (P< 0.01) were found between the
TNF- and PASI score, MMP-9, MMP-2, VEGF& E-selectin (r=0.85, 0.84, 0.58, 0.63, 0.67
respectively), as well as between the MMP-9 and PASI, MMP-2, VEGF& E-selectin (r=0.82,
0.39, 0.69, 0.41 respectively) of patients with PsA after pioglitazone treatment. In psoriatic
patients without psoriatic arthritis after pioglitazone treatment there were also significant
positive correlations between the TNF- and PASI score ,MMP-9, MMP-2, VEGF& E-
selectin(r=.0.87, 0.68, 0.53, 0.61, 0.51 respectively), as well as between MMP-9 and PASI,
MMP-2, VEGF& E-selectin (r=0.95, 0.51, 0.58, 0.45 respectively).
: The current study shows the existence of a direct relationship between MMP-
9 and TNF- production strongly suggesting that MMP-9 may play a key role in the skin
inflammatory process. Our findings also demonstrated that pioglitazone could be considered as
an efficacious and safe agent for the treatment of psoriasis. The optimum dose and duration of
pioglitazone therapy remain to be determined.

Introduction The nocturnal application of nasal continuous positive airway pressure is
used for treatment of sleep apnoea. The study of the histopathological changes that accompany
its application is needed for proper evaluation.
Subjects and Methods: Fifteen adult rabbits were used in this study, 14 were the subject
of the experiments and one animal used as control. Under combined general and local
anaesthesia, ring of skin and epithelium was removed from the left nostril, the margins of the
wound were undermined, averted and brought together with mattress sutures, effectively closing
the nostril. The animals were sacrified at intervals. The duration of surgical closure of one
nostril was four days in 7 animals and three months in 7 others. Strip of bony and cartilaginous
septum was removed after marking the closed side with a silk stitch. In each interval 4 animals
were used for transmission electron microscope (TEM) and 3 for scanning electron microscope
Results: On the side with sealed nostril the number of goblet cells increased, while the
number of ciliated cells decreased. In contrast, on the open side of the nose disappearance of the
ciliated cells and a transformation of the respiratory epithelium into thickened multilayered
squamous epithelium with no goblet cells.

: Conflicting results on the association between serum retinol level and bone
mineral density (BMD) have been published. Thyroid hormones are essential for skeletal
development and have direct effect on bone formation and resorption. Bone has one of the
highest concentrations of zinc of all tissues, and has been shown to release zinc during
deficiency for soft tissue metabolism. Objective: The objective of this study was to assess the
relation between plasma levels of retinol, thyroid stimulating hormone (TSH) & zinc and BMD
of Egyptian adolescents and adults. Method: The study was a part of a cross sectional national
survey conducted by National Nutrition Institute. The sample was a multistage stratified
random. Target individuals were classified into two age groups (10- 18 and 28- 59 years).
Bone mineral density and plasma levels of retinol, TSH and zinc were determined. Results:
Low and high plasma retinol levels were more prevalent among osteoporotic adolescent and
adult males respectively than in normal subjects.. The reverse was observed in adult females.
Bone mineral density correlated negatively with plasma retinol level in adult males and females
and positively in adolescent males, while among females the association was significant (P =
0.030) and stronger. The highest deficiency of TSH was found among adult and adolescent
osteoporotic males, followed by osteopenic adult males and adolescent females. Highly
statistically significant difference (P < 0.001) existed between osteoporotic and normal adult
males concerning TSH deficiency. The prevalence of zinc deficiency ranged from 5.7% to 9.5%
for all target individuals. Plasma Zn levels were correlated negatively with bone mineral density
in adult males and females. Conclusion: The results of this study reflects the controversy on the
association of plasma retinol and BMD. However, the predominant finding revealed that both
low and high plasna retinol levels compromise bone health. Bone status and thyroid function
support the adverse effect of hyperthyroidism upon either bone osteoporosis or osteopenia and
subsequently upon fracture risk. Plasma zinc deficiency correlated negatively with BMD in
adult osteoporotic men.

Background: Carnitine is essential for fatty acids translocation, muscles function and
exercise performance. Choline is a lipotropic agent that prevents deposition of fat in the liver.
The studies concerning the effects of carnitine and choline supplementation with exercise on
carnitine status and serum leptin are rare. The aim of the present study was to study the effect
of carnitine and its combination with choline, with or without exercise on body and total fat pad
(TFP) weights, serum carnitine, leptin, -hydroxy butyric acid (-HBA), triacylglycerols (TAG)
and Free Fatty acids (FFA). Also, total lipids (TL) and TAG content of TFP and urinary
carnitine were investigated.
Material and Methods: 48 male rats were equally divided to the following groups: control
(C), carnitine (5 g/Kg diet) supplemented, carnitine plus choline (5 and 11.5 g /Kg diet
respectively) supplemented. Half of each group was subjected to short term aerobic exercise on
manual treadmill, in which the speed and duration were gradually increased via the course of
the experiment, to be 10 m/min for 20 min/day, 5 days/week in the last 2 weeks. Body weights
were recorded weekly. After 6 weeks, The 24 hours urine was collected then the fasted rats
were sacrificed and blood and the total fat pad (TFP) were collected for analysis.
Results: Carnitine supplementation, tended to decrease body weight, TFP, TAG content
and serum FFA, and significantly decreased the TL content, serum leptin, TAG (P<0.0005).
Carnitine feeding resulted in a significant elevation of serum carnitine, -HBA and urinary
carnitine (P<0.0005), compared to sedentary control rats. These values became more
pronounced on choline addition to the diet except for serum and urinary carnitine that reversed
(i.e. decreased) by choline addition. Exercise intervention resulted in a significant decrease in
body weight, TFP, TL content and serum leptin, TAG and FFA. These values were more
pronounced in both supplements with exercise, specially serum carnitine. However, exercise
caused reduction of urinary carnitine in non-supplemented and carnitine supplemented groups
and this was reversed by choline and exercise.
Conclusion: Our study demonstrated that the beneficial effects of carnitine supplements
is promoted by choline with or without mild exercise to reduce body weight, body fat, serum
leptin and promote fat loss by increasing lipolysis as indicated by increased serum -HBA.
These results may or may not be applicable to humans, so further research is recommended to
determine whether similar effects would result in humans or not.

Aim: To study serum leptin level in chronic renal failure (CRF) patients on different
modes of management and to analyze the impact of the mode of therapy on serum leptin level.
Subjects and Methods: This study was conducted on 64 patients (33males&31females)
with chronic renal failure divided into three groups: group I: Twenty-six patients treated
conservatively and did not start dialysis yet (predialysis), group II: Twenty-four patients treated
by hemodialysis, group III: Fourteen patients treated by continuous ambulatory peritoneal
dialysis (CAPD). Twenty healthy subjects were included as control group. All patients and
controls were subjected to full clinical examination including height and weight to calculate
body mass index (BMI). Blood urea and serum creatinine were measured as renal function tests.
Serum leptin was measured by EASIA and so serum insulin.
Results: In predialysis and CAPD groups, there is a significant increase in leptin , leptin/
BMI and insulin in patients in comparison to control subjects. In hemodialysis group, there is a
significant increase in leptin and leptin/ BMI and a non-significant increase in insulin level in
patients in comparison to control subjects. Insulin is significantly correlated with leptin in the
first group, while in the second and third groups there is no correlation. The highest leptin level
is found in the CAPD group of patients followed by the predialysis one then the hemodialysis
Leptin level is significantly higher in females than males in all groups. This difference
remained after adjusting leptin level to BMI.
No correlation was found between leptin level and age or between leptin level and renal
function in the three groups of patients. No correlation was found between leptin level and the
duration of dialysis in the hemodialysis and CAPD groups.
Conclusion: Serum leptin is elevated in CRF patients irrespective of the type of
management they are undergoing. Dialysis, has no significant effect on leptin level. The two
main predictors of serum leptin level are sex and BMI in CRF patients and in healthy subjects.
Leptin level may serve as a valuable clinical marker for body adiposity.

The present study is an attempt to evaluate the protective effect of
schistosomula antigen and the current antischistosomal drug praziquantel (PZQ) as a reference
drug on mice infected with S. mansoni.
Material and Methods:
Mice were vaccinated by irradiated or non-irradiated
schistosomula antigen, both at a dose of 100 ug protein/mice once weekly for 3 weeks, before
infection with alive cercariae and compared with the treatment with i.m. injection of
praziquantel at a dose of 40 mg/kg b.wt. 4 times once weekly for 4 weeks after infection. The
degree of resistance or protection induced by immunization and chemotherapy was assessed 45
days post­infection and evaluated by physiological, parasitological, immunological as well as
histological parameters.
Results: The results indicated that immunization with -irradiated antigen at 20 Krad or
the treatment with PZQ resulted in significant reduction in ova count in liver and intestine
tissues more than those vaccinated with non-irradiated antigen compared with infected group.
Immunized group with irradiated antigen and the group treated with PZQ showed a significant
decrease in liver enzymes activity (ALT, AST and -GT), while in immunized group with non-
irradiated antigen, there was a significant increase in AST and -GT as compared to infected
group. The level of alkaline phosphatase enzyme was significantly increased in all investigated
groups compared to infected one. Treatment with PZQ or immunization with irradiated or non-
irradiated schistosomula antigen induced amelioration in serum IL-10 and TNF-. Scanning
electron microscope demonstrated normal mature worms in infected group after 45 days from
infection. In contrast, many changes were detected in the rest groups as alterations in the
tegument, implosion of tubercles which appeared pealed and sloughed off and most of the
spines were detached and separated.
Histological examination of liver sections of infected mice revealed lobular cellular
infiltration and cloudy swelling in hepatocytes with occurrence of necrotic foci. Also,
granuloma of infiltrating cells was noticed around the portal structures and inbetween the
degenerated cells. Congested portal vein could be seen lodged with adult worms and the portal
tracts showed fibrous thickening. Whereas, the lung revealed destructed bronchioles which
appeared surrounded by intense inflammatory foci. Thickened interalveolar septae were also
marked, however many alveoli appeared with shed destroyed epithelium. Moreover,
peribronchiolar and perivascular fibrosis was quite prominent. Gross pathological alterations
were observed in both liver and lung of immunized groups with non-irradiated antigen. In
controversy, immunization with irradiated antigen can reduce the granulomatous reaction and
collagen deposition. There are also little inflammation and less congestion, however the hepatic
and pulmonary architectures appeared otherwise normal. The present histological findings
proved that PZQ has a valuable schistosomicidal effect but some pathological changes are still
Conclusion: On the whole, it could be concluded that irradiated antigen produced marked
protection against S.mansoni infection and this may reflect its possible beneficial effect on the
diseased liver and lung.

The present work was planned to assess and evaluate some physiological
parameters, histopathological and histochemical impacts of sodium barbital on the liver of adult
male albino mice.
Material and Methods :The mice were divided into 3 groups, the first group served as a
control group, while the other two groups were treated with the therapeutic dose (60 mg/kg
b.wt., i.p.) for 7 days (short-term group) and 21 days (long-term group) as repeated daily doses.
Results: Biochemical analysis showed a significant increase in serum glucose level
(hyperglycaemia), AST, ALT and bilirubin, in all treated groups. Also, total lipids and
triglycerides showed a significant increase in the long-term group and non significant change in
the short-term group. On the other hand, alkaline phosphatase ALP, showed a significant
decrease in both treated groups. Total cholesterol level showed a significant decrease in the
short-term group but exhibited a significant increase in the long-term group. The results
obtained from the present study showed marked alterations in the liver tissue. Histopathological
changes in liver tissue were congestion of the central veins, wedening of the blood sinusoids,
activation of the phagocytic küpffer cells and cytoplasmic degeneration (fatty and hydropic)
with nuclear lesions. Histochemical changes in liver tissue revealed depletion of
polysaccharides and total proteins in both short-term and long-term groups.
Conclusion So these results came to conclusion that barbiturates should be prohibited and
carefully used specially when prescribed as tranquilizer.

Introduction:- Regional analgesia provides excellent pain relif in labour. This study was
designed to compare combined spinal eqidural (CSE) versus epidural block using a narcotic
(sufentanil) and local anaesthetic bupivacaine regarding their effects on progress of labour,
method of delivery, pain relif, side effects and neonatal outcome.
Patients and Methods :-Forty pregnant women ASA I and II were enrolled in this study.
The women were randomly allocated to receive either CSE or epidural ( 20 patient of each ). In
CSE group analgesia was initiated with 10ug sufentanil with 2mg bupivacaine. In epidural
group 10ml bupivacaine 0.125%.and 10ug sufentanil injected epidurally. In both groups the
continuous infusion of 0.83% bupivacaine with 0.33ug/ml sufentanil at 10ml/hr adjusted as
required. Maternal haemodynamics, analgesia characteristics VAPS, degree of motor block,
were measured. Duration of labour, cervical dilation, maternal satisfaction and mode of delivery
were assessed. Foetal outcome was assessed by 1 and 5 min. Apgar score and umbilical venous
blood gases. Maternal and neonatal side effects were observed.
The experimental study was done on 30 rats divided into 3 groups 10 rats of each. Control
group (A) injected intrathecally with saline, group (B) injected intrathecally with 1.5ug/kg
sufentanil (low dose), and group (C) injected intrathecally with 7.5ug/kg sufentanil (high dose),
the pervious doses were injected every 2hr. for 3 times then the spinal cord was obtained and
stained for histological evaluation.
Results:- The clinical study showed that no difference between the 2 groups for the degree
of motor block or adequacy of analgesia, mode of delivery and Foetal outcome. The onset of
analgesia was faster with CSE technique, more patient satisfaction and more pruritis.
The histological results revealed that no detectable significant neurotoxic changes with the
use of small dose of intrathecal sufentanil but mild changes occurred with high dose.
Conclusion :- So the study concluded that both CSE and epidural analgesia with sufentanial
and bupivaine can provide effective labour analgesia with minimal or no side effects.

Abstract :

Introduction : The interscalene approach to the brachial plexus for shoulder surgeries
provides excellent anaesthesia with remarkable safety and minimal or no systemic
Material and Methods : 60 abult patients ASA I-II undergoing elective shoulder surgery.
Patients were randomly allocated into 3 groups. The patients recived 20ml of either ropivacaine
1% GI (20 patients), ropivacaine 0.75% GII (20 patients) and bupivacaine 0.5% GIII (20
patients). Onset time of sensory and motor block, duration of analgesia and the need for
supplementary analgesics were recorded. Pain was assessed by using VAPS. Haemodynamic
parameters, oxygen saturation and respiratory rate were recorded. Unwanted side effects,
cardiovascular, neurological, nausea and vomiting etc were recorded. Also, patients satisfaction
were noted.
The pharmacological study was done on pentobarbitone cats to determine the effect of
different doses of ropivacaine (0.35-2.8mg/kg) versus buipvacaine (0.5-4mg/kg) on arterial
blood pressure, ECG and respiratory rate.
Results: The mean onset time of analgesia was faster in ropivacaine groups than
bupivacaine group (p<0.005). The studied groups were comparable regarding the duration of
analgesia, motor and sensory block, cadio vascular and respiratory effects. The incidence of
paraesthesia was more frequent in bupivacaine group than both ropivacaine groups (30% vs
10%) There was more patient satisfaction in ropivacaine groups than bupivacaine groups.
On the other hand the pharmacological study showed that ropivacaine had more less toxic
effects on cardiovascular and respiratory systems.
Conclusion : This study concluded that interscalene block performed with either 0.75% or
1% ropivacaine allows for a prolonged postoperative pain relief similar to bupivacaine 0.5%
with shorter onset time, more cardiovascular stability and higher patient satisfaction.

Cd 34 Glycoprotein as A Differentiating Marker Between Basal Cell
Carcinoma and Trichoepithelioma

(Cairo); Department of Pathology2 Al-Azhar university (Assuit)


Trichoepithelioma (TE) is a benign skin tumor with follicular differentiation, which is
sometimes difficult to distinguish clinically and histologically from basal cell carcinoma (BCC).
One of the most helpful differences is the histologic appearance of the stroma. CD34 is an
antigen known to stain the spindle shaped cells located around the middle portion of normal hair
follicles. We selected twenty clinically confused cases. After routine histopathological staining
by haematoxylin and eosin, all cases showed typical diagnosis in seventeen cases (9BCC& 8TE)
while the remaining three cases revealed overlapped features. Immunoperoxidase technique
using anti-CD34 antibody carried out in all cases displayed two out of the three overlapped
cases had a staining pattern similar to the typical BCC cases; the immediate tumor stroma
together with the spindle cells intermixing the tumor nests were CD34 negative. Moreover, the
remaining uncertainly diagnosed case had a pattern resembling the typical TE cases; the
immediate tumor stroma as well as the spindle cells surrounding the tumor islands were focally
CD34 positive.
From our study, we concluded that the CD34 staining pattern can be considered as a
helpful tool in differentiation between TE and BCC particularly when these lesians are in doubt
about the clinical or routine histologic diagnosis.

early revascularization post MI is the corner stone in the therapy of acute
myocardial infarction. Primary PCI proved itself in the management of STEMI with patency
rate more than 90%.However, not every hospital has PCI facility. New thrombolytic agent
(tenecteplase) is now available which can be given easily outside hospital (Prehospital) to
facilitate PCI and preserve the cardiac muscle.
Aim of the work:
comparing primary PCI results in patients with STEMI when
tenecteplase was given prior to intervention as early as possible (Prehospital), with those who
had only PCI without thrombolytic therapy.
Patients and Methods:
the presenting study included 60 patients, divided into two equal
groups, group I patients received tenecteplase followed by primary PCI and group II underwent
primary PCI only in acute STEMI. 12 leads ECG, cardiac enzymes, echocardiographic study,
and coronary angiography were done for all patients. PCI results were recorded in addition to
immediate and 6 month follow up. All patients received the same adjuvant medical therapy
(aspirin, clopidogrel, heparin and tirofiban if needed).
Results: both groups showed non significant differences in peak cardiac enzymes, ejection
fraction before and after PCI, and angiographic success post PCI. The hard end points (death,
MI) did not show statistical difference between both groups both inhospital and on follow up.
However group I showed significant difference (P<0.05) in more direct stenting, less procedure
time, and more recurrence of chest pain post PCI compared with group II. There were highly
significant differences( P<0.001) in favor of group I in more TIMI 3 flow, less thrombus
burden, and less pathological Q waves; and in favor of group II in more clinical success post
PCI without complications. The call to balloon interval was shorter in group II (P<0.05). No
major bleeding was seen in both groups.
Conclusion: facilitated PCI has the advantages of decreasing thrombus burden in acute
STEMI, decreasing procedure time and achieving more TIMI 3 flow; however the hard end
points are not different from primary PCI and the recurrence of chest pain is significantly more
with facilitation. Tenecteplase use is not associated with major bleeding before PCI.
KEY words: tenecteplase facilitated PCI, Prehospital thrombolysis.

Introduction: The usefulness of adriamycin (ADR), a potent anti-tumor antibiotic, is
limited by the development of life-threatening cardiomyopathy and nephropathy. The cellular
changes leading to these toxicities are suggested to be mediated by increased free radicals and
lipid peroxidation
Aim of the study: The current study was aimed to investigate the protective role of
simvastatin (SIM) on adriamycin-induced nephrotoxicity in rat using biochemical, and
histological approaches.
Material and methods: Twenty eight healthy male Swiss albino rats were used and
divided into four groups : CONT (control), ADR (adriamycin treated), SIM (simvastatin
treated), and SIM+ADR (simvastatin plus adriamycin treated). Blood samples were collected
and used to determine the serum urea, creatinine, albumin, and total protein levels. Both kidneys
were removed ,one of them was prepared for histological examinations and the other was
stored at -70 °C for subsequent measurement of malondialdehyde (MDA), glutathione (GSH)
contents and phase II antioxidants enzymes activities.
Results: Glutathione (GSH) level, glutathione-s-transferase (GST) and DT-diphorase
activities were decreased, while the lipid peroxidation was increased in kidney tissue.
Administration of SIM (cumulative dose, 60 mg/kg body wt) in 12 equal injections (PO), before
and concurrent with ADR, more or less prevented these nephropathic changes, normalized
kidney function, and eliminated ascitis. Treatment with SIM was also accompanied by an
increase in kidney GSH level as well as DT-diphorase activities with a concomitant decrease in
lipid peroxidation. Histological examination revealed extensive and marked tubular necrosis in
the ADR-treated kidney. Administration of Simvastatin reversed kidney damage with a marked
reduction in tubular damage induced by ADR
Conclusion: These data show that SIM can provide coma protection against ADR
nephropathy. This protective effect of SIM may be related to the antioxidant status on the kidney
