karbala journal of pharmaceutical sciences, 2013, Volume 4, Issue 4, Pages 1-10

Silibinin is a major biologically active compound present in the Compositae family of plants with promising antinflammatory activity. The purpose of this study was to develop and optimize formulations of mucoadhesivefilms of silibinin to be used for buccal ulcer.Twelve film formulas were prepared by the solvent casting method using several polymers namely: sodium carboxymethylcellulose (SCMC), polyvinylpyrolidone (PVP), polyvinyl alcohol (PVA), carbopol 934, Eudragit E-100, and sodium alginate at various ratios. The prepared films were characterized in terms of film thickness, weight variation, swelling capacity, surface pH,drugcontent uniformity, ex vivo adhesion time, bioadhesive strength, folding endurance, in vitro drug release, and drug-exicpient compatibility using FTIR. The in vitro release studies were conducted for silibininfilms in phosphate buffer-pH-6.6 solution.The films were found to be smooth in texture, uniform in thickness, weight, and drug content with acceptable surfacepH. The film formula (F12) containing combination of two polymers PVP: PVA in ratio of 1:3with 0.3%v/v propylene glycol showed good mucoadhesion properties with maximum release of 95% within 4 hours. The diffusion exponent (n) of KrosmeyerPeppas for best formulation was found to be 0.52 which indicates the mechanism of drug release was anomalous transport. Optimized formulation was checked for stability and was found to be stable with expired date about3.6 years. Thus the selected formula can serve as a good candidate for buccal dosage form of silibinin.

Acute Upper Gastrointestinal Bleeding is a common medical emergency and potentiallylife threatening condition that needs a prompt assessment and aggressive medical management. To assess the causes, risk factors, and management of acute upper gastrointestinal bleedingin Karbala city; 150 patients (58 females; 92 males) with acute upper gastrointestinal bleedingwere studied during the period of March 2011-March 2012 in Al-Hussein Teaching Hospital. Their age range was (14-89 yr). About 39% of cases were over 60 years old. Peptic ulceration was the commonest cause accounting for 63.3% of cases, followed by acute gastric erosions 18.7%,oesophagealvarices6.7%,and malignant ulcers 4.7%. Non-steroidal anti-inflammatory drug ingestion was the most important risk factor for acute upper gastrointestinal bleedingin addition to smoking and H. pylori infection. Co-morbidity was present in about50% of cases. The use of acid lowering agents such as proton pump inhibitors was the mainstay of therapy for patients with upper gastrointestinal bleeding followed by H2-antagonist. The mortality rate reported in this study was 5.3%. In conclusion, it appears that the most common cause of acute upper gastrointestinal bleedingis acid peptic disease, which increases with the increasing age, frequent consumption of non-steroidal anti-inflammatory drugs, smoking and H. pylori infection. Early diagnosis and prompt treatment are effective in decreasing mortality and morbidity.

Background: Benign prostatic hyperplasia (BPH) is a prevalent problem among older men . There is controversy about the risk factors that contribute to the development and aggravation of BPH, diet and obesity may have a major role in the development of BPH. This study investigate body mass index (BMI) as a marker of obesity, leptin level, and lipid profile in correlation with the prostate-specific antigen PSA in symptomatic BPH Iraqi patients.
Patients and Methods : Randomly selected twenty patients newly diagnosed with BPH visited Baghdad hospital for special surgery, including 10 non-obese patients with BPH,and 10 overweight or obese patients with BPH. Body mass index (BMI ) was calculated and blood samples were drawn to determine fasting blood glucose (FBG) , total cholesterol, triglycerides, HDL cholesterol , serum leptin , and prostate-specific antigen (PSA).
Results : BMI value ,Triglycerides , and serum leptin was significantly higher in overweight or obese patients ( p ˂ 0.05 ),and there was non significant high level of FBG , PSA , total cholesterol compared to non obese ( p ˃0.05 ). Significant lower level of HDL cholesterol was also noticed inobese patients (p ˂0.5 ). In non obese patients, . PSA correlated negatively with BMI,leptin, triglycerides and FBG, positively with total cholesterol and HDL cholesterol. While inobesepatients , PSA correlated negatively with BMI, leptin, HDL cholesterol,and FBG .PSA correlated positively with total cholesterol and triglycerides .
Conclusion :In this study , obesity marker like serum leptin ,BMI and triglycerides , was significantly higher in overweight/obese BPH patients compared to non obese,but correlated negatively with PSA (except with triglycerides) . Further research exploring relationship of diet, obesity with prostate cancer and BPH will lead to understanding of the complex inter-relationship.

karbala journal of pharmaceutical sciences, 2013, Volume 4, Issue 4, Pages 32-39

The first line drugs used for tuberculosis therapy are isonizid and rifampicin (INH
&RIF) and they are associated with hepatotoxicity, for this reason we aimed to study
the protective effect of morin on the hepatotoxicity induced by the tow
antituberculosis agents given together.
To reach study object 24 female Wistar albino rats 220-250 g were divided into four
groups, each group consisted of six animals received standard diet and tab water along
the 21 days which is the experimental period. The control groupleaved without
treatments while the morin group, rats were treated with 30mg/kg/day morin via
gavage along the days of the experiment. INF-RIF group, rats were treated with 100
mg/kg/day INH-RIF by intraperitoneal injection method for 21 days. INF-RIF and
morin group, rats were treated with 100 mg/kg/day INH-RIF plus morin with a dose
of 30 mg/kg /day via gavage along the experimental period.
The results had a significant increase in the activity of alanine aminotransferase,
aspartate aminotransferase and malondialdehyde level and significant decrease in the
activity of superoxide dismutase, glutathione peroxidase, glutathione s-transferase and
catalase in animal groups treated with INH and RIF as compared to control groups.
However, supplementation of INH-RIF intoxicated rats with morin ameliorated the
antituberculosis drugs adverse effects as evidenced by a significant decrease in
alanine aminotransferase, aspartate aminotransferase activity and malondialdehyde
level and significant increase in superoxide dismutase, glutathione peroxidase,
glutathione s-transferase and catalase. We concluded that morin have a potential to
protect the liver from INH and RIF toxicity.

Chronic telogen effluvium (CTE) was defined as a primary idiopathic disease entity in 1996. Women suffering from CTE present with an abrupt onset of generalized shedding of telogen hair from the scalp, with or without an identifiable trigger that persists for more than 6 months. Therefore this study is conducted to detect the association of serum zinc with CTE. The study included one hundred adult menstruating female patients with age ranged between 18-49 years, complaining of hair loss from the scalp and fifty ages matched healthy female controls. Both groups were evaluated for serum zinc levels. There was strong statistically significant reduction (p= 0.01) in the level of serum zinc in patients compared to that in control group.This indicating that there is a definite association between decreased serum zinc levels and CTE in adults menstruating females.

karbala journal of pharmaceutical sciences, 2013, Volume 4, Issue 4, Pages 136-144

Background: Oxidative stress is a common mechanism contributing for initiation and propagation of renal damage induced by several chemicals such as DDT. Silymarin, the dried extract of the ripe seeds of the plant Silybum marianum is found to be a powerful protective agent against toxin-induced tissue injury in many organs especially the liver by its antioxidant property; accordingly, the intended property needs to be clarified in other organ subjected to toxic chemicals.
Objective: The present study was designed to evaluate the possible protective effect of silymarin on the status of oxidative stress by measuring the levels of (MDA) and glutathione (GSH) in renal tissue in addition to assessment of the serum levels of urea and creatinine and examination of possible histological renal changes induced in rats by a toxic dose of DDT.
Methods: White albino rats were administered a single oral dose of DDT (100mg/kg) to induce renal toxicity. Silymarin was orally administered twice daily dose (500 mg/kg) for 7-days prior to DDT administration, then the animals were sacrificed 24-hours after DDT-treatment. The parameters of oxidative stress, MDA contents and GSH levels were measured in renal tissue homogenate. Blood was collected for measuring serum urea and creatinine levels, in addition to the histological examination of the kidneys.
Results: Treatment of rats with silymarin for 7-days prior to DDT administration caused a significant reduction in the contents of the lipid peroxidation end product, MDA down to (61%) with the increasing in the levels of GSH levels up to (82%) in renal tissue homogenate compared to DDT-treated animals. Furthermore, silymarin was able to counteract significantly the elevation in the levels of serum urea and creatinine by about 38% and 34%, respectively compared to DDT-treated rats. Sections of rats' kidney treated with silymarin 7 days prior to DDT administration, elicited improvement in the histopathological changes induced by DDT characterized by inhibition of cloudy swelling, inflammation and necrosis.
Conclusion: According to the results obtained from this study, it is conclude that silymarin have antioxidant property through direct and/or indirect mechanism that provide protective effects against DDT-induced nephrotoxicity, and makes it a good candidate to be tried clinically in this respect.

karbala journal of pharmaceutical sciences, 2013, Volume 4, Issue 4, Pages 155-165

Chronic kidney failure (CKF),is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are unspecific, and might include feeling generally unwell and experiencing a reduced appetite. Free radicals are formed in all living organisms during normal cell metabolism. Patients with chronic renal failure who are regularlydialyzed are candidates for free radical damage.The current study investigate possible links with total acid phosphatase, prostatic acid phosphatase, total and free prostate-specific antigen ,several Antioxidants and an increased risk of prostate disease present in males with chronic kidney failure (CKF). The present study is also to compare these features level among patients [chronic renal failure] undergoing haemodialysisand in control (age and sex matched)therefore, addressed this question by measuring prostatic markers in patients receiving long-term dialysis.Patients were chosen from the patients referred to the Medical City –Kidney Transplant Center, Iraq.The glomerular filtration rate (GFR)has been measure in 45 patients with CKF using haemodialysis method . Laboratory investigations including kidney function, serum urea, creatinine, albumin, S. calcium, S. Phosphorus, total protein, Uric acid, S. potassium, S. Sodium,Hb, in addition to serum total antioxidant capacity(TAC), lipid peroxidation(the level of lipid peroxidation expressed as malondialdehyde(MDA)) ,vitamin E, vitamin C and total acid phosphatase, prostatic acid phosphatase, total and free prostate-specific antigen had been measured in male with CKF . Blood samples were obtained from the patients and the control group consisted of 25age and sex matched normal healthy individuals who came to the hospital for health checkup.Hemoglobin, Serum urea,creatinine,GFR, S. calcium, potassium,PSA, fPSA, PAP,LH, TAC,MDA, uric acid , vitamin E, vitamin C showed significant difference between the patients and control group. There was a positive correlation in PSA[ng/ml] with TAC (r=0.57, p<0.01), MDA (r=0.60, p<0.01),While PSA correlated negatively with Vitamin E (r=-0.65, p<0.01), Vitamin C (r=-0.57, p<0.01) in the CKF patients while there was no significant correlation was observe in the control group. In this study, a significantly negative association was observed between PAP[IU/L] with TAC (r=-0.63, p<0.01), MDA (r=-0.70, p<0.01),in the CKF patients while there was no significant correlation was observe in the control group. A significant positive correlation was found between PAP[IU/L] , and Vitamin E (r=0.61, p<0.01), Vitamin C (r=0.67, p<0.01).Hemodialysis leads to significant changes in the antioxidant system of the blood of patients with chronic renal failure. Despite an adverse metabolic environment in chronic renal insufficiency, Prostatic disease markers were useful in the routine screening of men receiving long-termdialysis, but the clinicians should be on alert when the dialysis duration increasesthe change in serum anti oxidants that accompanies decline in renal function.

Nizar A. Jassem; Nawal A. Rajab

karbala journal of pharmaceutical sciences, 2013, Volume 4, Issue 4, Pages 166-176

Famotidine is histamine H2 receptor antagonist; it is widely used in treatment of gastric ulcer and gastroesophageal reflux disease. The low bioavailability (40-45%), short biological half life (2.5-4 hrs) of famotidine in addition to have an absorption window, this favor the development of controlled release gastroretentive dosage forms of the drug.
In this study, the floating beads of famotidine by ionotropic gelation technique were formulated in two different combinations such as sodium alginate withhydroxypropyl methyl cellulose(HPMC) and sodium alginate with guar gum. The effect of CO2 gas forming agents such as CaCO3 or NaHCO3 on drug loading, % drug entrapment efficiency, floating properties and invitro drug release were evaluated.
It was found that as the ratio of gas forming agents increased from 0.2 to 1 , the floating property was increased for both type of gas forming agents while % entrapment efficiency of famotidine beads are decreased from 86.11 % to 68.5% for CaCO3 and from 84.3% to 60.7% for NaHCO3 .
Increasing the CaCO3 ratio did not appreciably accelerate drug release as compared with NaHCO3, indicating that CaCO3 is superior to NaHCO3 as gas forming agent in floating beads of famotidine.
On the other hands, beads containing guar gum produce more sustained release of famotidine than that beads containing HPMC.
Furthermore, the release mechanism were investigated and the results indicate that most of the formulations follow Higuchi modelwith non fickian anomalous drug release behavior.
