ABSTRACT
Background:
asthma Control Test (ACT) Questionnaire is developed to meet the guidelines internationally
accepted for asthma management by measuring adequacy and any alteration in control of asthma, occurring
spontaneously or after starting asthma management. Objectives: to assess control of asthma in a sample of
patients diagnosed as asthmatics in Taif City based on Asthma Control Test (ACT) Methods: fifty
asthmatic patients, from those attending the out patients clinic in King Abdul Aziz Specialized hospital and
chest hospital in Taif city, were included in this study in the period from July to December, 2013. Patients
were subjected to: full clinical history and examination for clinical classification of the disease and to
recognize controlled from uncontrolled patients; review for the treatment plan for each patient; (ACT)
questionnaire was used to identify patients with poorly controlled asthma. Results: clinical classification of
asthma showed that 20% of patients had intermittent asthma, 24% had mild persistent asthma, 32 % had
moderately persistent asthma and 24% of patients got severe persistent asthma. According to ACT only
24% of patients were controlled, while the rest of patients 76% were considered uncontrolled. Conclusion:
ACT was found to be a reliable tool for assessment of uncontrolled asthmatic patients when implemented in
Taif city. Recommendations: conduct more studies in different geographical areas to assess effectiveness
of the AST questionnaire in different situations and different asthmatic patients.
Keywords: Asthma, Asthmatic Patients ,Taif City.

ABSTRACT
Background:
examining the alteration of cell cycle genes in early hepatitis C virus (HCV) found that altered
expression of mitotic checkpoint genes, MAD2L1, KNTC1, CDC16 and CDC34, KNTC1 known as "rough
deal protein" (ROD) is part of a complex involved in elaborating an inhibitory signal due to improper
chromosomal aligment during cell division.
Aim of the work: attempt for the identification of proteins (genes), which act as predictive factors to
identify patients with high risk of cell transformation and HCC development.
Patients and methods: fifty three patients with chronic HCV infection, age ranged between 18 and 58 years,
time of assessment was before starting therapy of hepatitis C at the National Hepatology and Tropical
Medicine Research Institute. Ten healthy individuals were included to serve as controls. All the patients and
controls were subjected to the following: history, clinical examination, abdominal ultrasonography, and
collection of blood samples for routine laboratory investigation; CBCs. Liver biopsy was done to all patients
and controls, patients revealed mild fibrosis (Metavir fibrosis scores from F1 to F3). Also, we used freshly
frozen liver biopsies mRNA levels with perspective protein levels of four genes: P27, P15, KNTC1,
MAD2L1. Results: significant association of P27, P15, KNTC1 and MAD2L-1 with the progression of liver
fibrosis in chronic HCV liver biopsy was found. Conclusion: there is altered gene expression in HCV-
associated liver disease. Recommendations: the emerging interest of hepatologists in the influence of
genetic factors in HCV. Evaluation of the expression of key proteins related to the cell cycle and apoptosis in
chronically infected patients with HCV would be of significance to understand disease pathogenesis, and
will help in identifying novel prognostic indicators.

ABSTRACT

Background:mitomycin-C (MC) is an anti-cancer drug against several tumor types, including colon,
breast and head and neck. In this demonstration, the genotoxic effects of mitomycin-C on DNA content and
testicular tissue of male albino mice Mus musculus were studied.Materials & Methods: mitomycin-C treated
animal was injected intrapretonialy with tested doses of mitomycin-C single time at the first day of the
experiment. Comet assay was used to detect the DNA damage in mice lymphocytes and the mean of total
comet score was increased by dose and time among all treated groups. Results:the histological alterations
caused in the testis of mice after mitomycin-C treatment displayed variable changes in both the seminiferous
tubules and the interstitial tissue. Changes in seminiferous tubules were represented by hypoplasia of the
germinal epithelium and spermatogenic arrest at various stages of spermatogenesis. The most prominent
changes reported in the intertubular tissue were represented by the presence of a homogeneous and intensely
eosinophilic ground substance in the interstitial areas, congestion of blood vessels as well as haemorrhage. The
histological changes were also significantly increased by time and dose.

ABSTRACT
Background:
Bisphenol A (BPA) is an environmental chemical that has beenwidely used in the
manufacture of polycarbonate plastics andepoxy resins for many years. Due to its major applications
inthe production of plastic food or beverage containers andthe coating of food cans, people of different
ages are inevitably exposed to BPA in daily life. It is a contaminant with increasing exposure to it and
exerts both toxic and estrogenic effects on mammalian cells. Aim of the work: the present study was
designated to evaluate the histopathological and immunohistochemical effect of BPA on the
histoarchitecture of pituitary ,adrenal,ovarian and uterine axis of female albino rats and the ameliorative
effect of antiestrogen drug and stem enhance Experimental model and methods: 20 female albino rats
weighing 100 120 g. were kept under observation for about 15 days before the onset of the experiment
for adaptation, then the rats were classified into 4 groups 5 rats for each , the first group was left
without any treatment for 30 days as negative control group , the second group was administered with
20 mg/kg.bw of BPA for 15 consecutive days as positive control, the third group administered with 20
mg/kg.bw of BPA for 15 consecutive days and then treated withantiestrogen drug as 0.1 mg/100gm.bw
for 15 day, the fourth group administered with the same dose for the same period and the treated with
stem enhance (4.5 mg/100.bw) for 15 days.All rats are scarified and organs were histologically examined

ABSTRACT
Background:
vitamin D is a fat-soluble vitamin; it has skeletal and non-skeletal functions. The effect of
Vitamin D on CV disease had several mechanisms including elevated PTH and Calcium-phosphate
metabolism. It decreases the pro- remodeling of Angiotensin II on the cardiomyocytes.
The Objectives: to study relation between serum levels of vitamin D and echocardiographic
determinants of systolic and diastolic functions in patients with and without cardio-renal syndrome.
Patients and Methods:
prospective study was conducted on 90 patients of all age groups and both
sexes, admitted to Ain-Shams University hospital. The study included 3 groups of patients: Group 1:
systolic dysfunction and renal insufficiency (30 patients), Group 2: systolic dysfunction only (30
patients). Group 3: renal insufficiency only (30 patients), in addition 10 healthy controls were taken as
controls. Patients were subjected to full comprehensive echocardiography and KFT with estimation of
creatinine clearance, and Vitamin D level that was statistically studied against echocardiographic
parameters of cardiac systolic and diastolic function. Results: our study found that, compared to patients
with normal vitamin D level, patients with vitamin D deficiency (defined as having vitamin D level <20
ng/ml) had significantly higher ventricular thickness (IVS, PW and mean wall thickness) (P value <
0.001), and higher LV mass which seems to be linked eventually to worse outcomes with no significant
impact on worsening Diastolic dysfunction. A ROC curve was done revealing a sensitivity of 80% for
the mean wall thickness ( 10 mm) to identify patients with vitamin D deficiency.
Conclusion: Vitamin D deficiency was associated with ventricular hypertrophy with worsening
outcomes with no impact on diastolic function.
Key words: Vitamin D deficiency, Systolic heart failure, Diastolic dysfunction.

ABSTRACT
Background: Premature ventricular beats (PVBs) are early depolarization of the myocardium
originating in the ventricle, the prognosis in patients with frequent PVBs and no obvious organic
heart disease is usually very good. However, many patients are severely symptomatic with impaired
quality of life.
Aim of the study: We aimed at our study to assess the success of radiofrequency catheter ablation
of monomorphic PVB and its impact on improvement of left ventricular (LV) systolic functions.
Patients and Methods: The current study was conducted on 40 patients with frequent symptomatic
monomorphic PVBs, candidate for PVB radiofrequency catheter ablation in cardiology department,
Ain Shams University, between 2013 and 2015. All patients were subjected to thorough history
taking, complete general and local examination, conventional 2D echocardiography and pre-
procedural Holter ECG monitoring. Patients were divided to two groups (20 patients in each group)
according to the presence or absence of structural heart disease. Electrophysiological mapping and
ablation was done for all patients, and their clinical, electrophysiological and procedural aspects
were analyzed. Follow up echocardiography and Holter ECG monitoring was done 3-6 months later
to assess recurrence and impact on LV internal dimensions and systolic functions.
Results
: Acute success was achieved in 35 patients (87.5%), and long term success was achieved in
30 patients (75%), with elimination of PVBs and distressing symptoms among group of patients
with procedural success. Presence of structural heart disease was not related statistically to
procedural failure or long term recurrence. Magnitude of reduction of PVB burden had significant
correlation with improvement of systolic functions (P=0.04). Significant improvement of
echocardiographic parameters was witnessed among group with baseline LV systolic dysfunction.
Conclusions: Radiofrequency catheter ablation is an effective and safe therapeutic tool for frequent
monomorphic PVBs and should be addressed as 1st line option for reversal of PVB induced LV
systolic dysfunction.
Keywords: PVB, electrophysiology, radiofrequency ablation.

ABSTRACT
Background:
the transfemoral approach (TFA) has been until presently the main-stay for arterial access PCI
in the setting of acute STEMI, while the transradial approach (TRA) is gaining ground in elective as well as
primary procedures.
Objectives: to assess the impact of transradial versus transfemoral approach for PCI on the outcome of
patients presenting with acute coronary syndrome.
Patients and Methods: prospective study was conducted on 100 patients presenting to Ain Shams
University Hospitals Coronary Care Unit (CCU) with recent onset acute coronary syndrome (whether
unstable angina (UA)/nonST-segment-elevation MI (NSTEMI) or ST-segment-elevation MI (STEMI))
undergoing revascularization via percutaneous coronary intervention (PCI). Patients were randomized into 2
equal groups, for the first group PCI was performed via TFA while for the second group via TRA.
Results: our study found that, with TRA we get less bleeding, less local vascular complications [8 (16%) vs
2 (4%), p=0.045] & less amount of dye used (169.60 21.28 versus 187.00 37.65 ml, p=0.006) without
significant increase in fluoroscopy time (10.86 4.88 versus 9.76 4.74 mins, p=0.256) or radiation
exposure. Although there was no significant difference in mortality and morbidity, TRA offers the patient a
more simple procedure with less hospital stay (3.4 0.948 versus 3.86 0.808 days, p<0.01).
Conclusion: radial artery access is a safe and effective approach for management of ACS. If performed by
experienced operators, TRA should be the standard access in managing ACS specifically in STEMI.
Keywords: Acute coronary syndrome, transfemoral approach, transradial approach.

ABSTRACT:
Backgrounds:
Natural remedies were used for cancer treatments, particular breast cancer. Also, the
consumption of food products containing high amount of flavonoids and antioxidants had reported to
lower the risk of various cancers. Bee venom (BV) and propolis were produced by honey bee. They
were characterized by naturopathic formulation, affordability and containing high amount of
antioxidants. Moreover, they were used safely since ancient times globally. Although that, there is no
information about the synergistic or antagonistic anticancer effects of their combination. This study was
designed to evaluate cytotoxic and pro-apoptotic effects of BV, propolis, and their combination on
breast cancer (MCF-7) cells. Materials and Methods: As preliminary study, MCF-7 cells were treated
with BV (5, 10, and 20g/ml) and propolis (50, 150, and 450g/ml) to specify the desired combination
doses of each treatment with no anticancer effect individually. Consequently, doses of (5g/ml BV+
50g/ml propolis and 5g/ml BV+ 150g/ml propolis) were chosen to evaluate the possible synergistic
anticancer potential between them. All groups in this study were examined at 2, 4, and 12 hours
intervals. The morphological changes were evaluated by acridine orange/ ethidium bromide dual
fluorescent staining and Giemsa staining to reveal the formation of apoptotic bodies or nuclear
condensation and cytoplasmic blebbing, respectively. DNA fragmentation assay was also carried out to
record the reduction in DNA content and apoptosis. Bcl-2 expression, cytoplasmic anti-apoptotic
marker, was used to prove the apoptotic properties, and autophagic cell death by florescent microscopy
was evaluated also. Results: Morphological observation by inverted and florescent microscopy revealed

hand, the results of combined treatments revealed significant morphological alterations after fluorescent
and Giemsa staining. Apoptotic DNA fragmentation was clearly observed and Bcl-2 recoded significant
down regulation which proved the apoptotic properties of combined treatments. Additionally,
autophagic degradation results also supported the occurrence of stress on treated cells leading finally to
cell death. All results of powerful anticancer potential were obvious among all combined-treated groups
in dose and time dependent manner. This clear that, the combined treatments have possible synergistic
effect which, propose it as potential candidates to be used in development of chemotherapy.

ABSTRACT
Background:
Diabetes mellitus continues to be a public health concern. Vitamin D had sparked
widespread interest in the pathogenesis and prevention of diabetes. The aim of this study was to
investigate the effect of vitamin D (deficiency & treatment) with alteration in fasting plasma glucose,
insulin resistance in alloxan injected rat. Materials and methods: The experiment was carried out
using 40 male albino rats (Sprague Dawley) weighing 15010g. Animals were randomly divided into
three groups; first group fed standard diet as a negative control group. Diabetic group injected
subcutaneously by alloxan, and fed on standard diet. The third group fed standard diet without vitamin
D for two weeks. After that glucose and insulin were determined in each rat of all groups to insure
alteration in fasting plasma glucose, insulin resistance, Homeostasis model assessment insulin
resistance (HOMA-IR) was calculated. Then the third group was divided to two subgroups. The first
subgroup fed basil diet with required vitamin D; while the second subgroup fed standard diet with
double dose vitamin D. At the end experiment (4 weeks), glucose, insulin, lipid profile, liver and renal
functions were determined in blood and serum, while (HOMA-IR) and LDL were calculated for
normal, diabetic group and both treatment subgroups. Results: Vitamin D deficiency group had the
nearest results to the diabetic group injected with alloxan group in: insulin, glucose and HOMA-IR.
Other groups had lower level than the other two groups in the same parameter. Our data explained the
improvement in glucose level after feeding with vitamin D. Diabetic group injected with alloxan had
increased in liver enzymes, renal function and lipid profile compared with other groups and showed
variable changes in histopathological examination. Conclusion: Vitamin D deficiency status is
associated with a higher risk of type 2 diabetes. Vitamin D improves glucose tolerance and insulin
sensitivity. Vitamin D has also been shown to reduce the risk of diabetes associated complications.

ABSTRACT

Background and Objectives :Warfarin is the most widely prescribed oral anticoagulant; it is highly
effective for the treatment and prevention of venous and arterial thrombosis. The beneficial outcomes of
warfarin therapy are dependent upon achieving and maintaining an optimal international normalized ratio
(INR) therapeutic range. The aim of this study was to evaluate the impact of our newly established clinic
at Queen Alia Heart Institute (QAHI) in the Royal Medical Services (RMS), Jordan.
Patients and Methods:An observational prospective study was carried out in a newly established
anticoagulation clinic managed by two clinical pharmacists and one nutritionist in QAHI since September
2013 until June 2014. The patients (no= 250) who were on warfarin for at least two months referred to the
clinic were included in our study. All patients or their care givers received a 45 minutes educational
session and a warfarin booklet. Then they were followed up regularly for achieving and maintaining the
target INR and developing any adverse events related either too high or low INR (>4.5 or <1.5,
respectively).Results:The age range of this group of the patients who were referred to t he clinic was
wide, 5-81 years. 65% of them were males, with the most common indications for Warfarin were aortic

ABSTRACT


Background: Diabetes mellitus is associated with biochemical and pathological alterations in the liver.
The aim of this study was to investigate the effects of apple cider vinegar (ACV) on serum biochemical
markers and histopathological changes in the liver of diabetic rats for 30 days. Effects were evaluated using
streptozotocin (STZ)-induced diabetic rats as an experimental model. Materials and methods: Diabetes
mellitus was induced by a single dose of STZ (65 mg/kg) given intraperitoneally. Thirty wistar rats were
divided into three groups: control group, STZ-treated group and STZ plus ACV treated group (2 ml/kg
BW). Animals were sacrificed 30 days post treatment. Results: Biochemical results indicated that, ACV
caused a significant decrease in glucose, TC, LDL-c and a significant increase in HDL-c. Histopathological
examination of the liver sections of diabetic rats showed fatty changes in the cytoplasm of the hepatocytes
in the form of accumulation of lipid droplets, lymphocytic infiltration. Electron microscopic studies
revealed aggregations of polymorphic mitochondria with apparent loss of their cristae and condensed
matrices. Besides, the rough endoplasmic reticulum was proliferating and fragmented into smaller stacks.
The cytoplasm of the hepatocytes exhibited vacuolations and displayed a large number of lipid droplets of
different sizes. On the other hand, the liver sections of diabetic rats treated with ACV showed minimal toxic
effects due to streptozotocin. These ultrastructural results revealed that treatment of diabetic rats with ACV
led to apparent recovery of the injured hepatocytes. In prophetic medicine, Prophet Muhammad peace is
upon him strongly recommended eating vinegar in the Prophetic Hadeeth: "vinegar is the best edible".
Conclusion: This study showed that ACV, in early stages of diabetes induction- can decrease the
destructive progress of diabetes and cause hepatoprotection against the metabolic damages resulting from
streptozotocin- induced diabetes mellitus.
Keywords: Streptozotocin, Diabetes mellitus, apple cider vinegar, Liver, Rat.

against Methotrexate Induced Liver Injury in Rats.
Gehan A. Youssef
Physiology Department , Faculty of Medicine (Girls), Al-Azhar University.

ABSTRACT
Background
Ginseng, an ancient and famous medicinal herb in the Orient, has been used as a
valuable tonic and for the treatment of various diseases including hepatic disorders. Ginseng extracts
and individual ginsenosides have shown a wide array of beneficial role in the regulation of regular
liver functions and the treatment of liver disorders.
Objective: This study tries to determine the hepatoprotective , antioxidant and anti-inflammatory
effects of ginseng on Methotrexate (MTX)-induced hepatotoxicity
Materials and Methods: forty rats (weigh 150-180 g) were used. The rats were kept in animal
house for one week and had access to water and food . Temperature was kept at 37 C. After one
week, the rats were randomly divided into four equal groups: Group (A) (control) received normal
saline ; group (B )received Ginseng(1.8 ml/kg/day) orally ; group( C) received MTX (100 g/kg)
intraperitoneally and group (D) received MTX (100 g/kg) intraperitoneally with ginseng (1.8
ml/kg/day) orally. After six weeks, the rats were decapitated and evaluation of liver function was
done.
Results: Ginseng treatment markedly suppressed the serum alanine aminotransferase (ALT) ,
aspartate aminotransferase (AST) and serum gama glutamil transpeptidase (GTP) activiteis .
Ginseng was attributed to stimulate anti-oxidant protein contents, such as glutathione peroxidase
(GPX). The marked increase of proinflammatory cytokines ( TNF ) in MTX treated rats group
was additionally attenuated by ginseng,
Conclusion : Ginseng effectively prevent liver injury, mainly through down regulation of oxidative
stress and inflammatory response.
Key words: Ginseng ,methotrexate, liver, anti-inflammatory activity, antioxidant.

ABSTRACT
Materials and methods: Nine fungal isolates namely Emericill anidulans, Mucor racemosus , Alternaria
pluriseptata Penicillium canescens, Syncephalastrum racemosum, Aspergillus fumigatus, Alternaria
chlamydospora, Aspergillus parasiticus
and Ulocladium atrum were isolated from AL SHEGA area at
AL- QASSIM region. Results: The influence of different sodium chloride concentrations on the growth
rate, morphological and ultrastructure were studied. Considerable differences in their growth rate and
morphology were detected on medium containing different concentrations of sodium chloride (NaCl). Low
growth rates were obseved on high NaCl concentrations . At 15 % NaCl, low growth of Emericill
anidulans, Penicillium canescens, Syncephalastrum racemosum, Aspergillus parasiticus
and Mucor
racemosus
was detected , whereas all fungal isolates were failed to grow at 20% NaCl. Scanning Electron
Microscope (SEM) revealed that all fungal asexual reproduction organs were metamorphosed at higher NaCl
concentration, fungal heads and sporangia were speculated or elongated. Sporangiophores and conidiophores
were shortened and dwarfed ,little number of conidia or spores were detected.
