Objective: To determine the effect of obestatin administration on FSH, LH, testosterone, leptin and MDA levels in obese Sprague Dawley Rats. Study Design: Laboratory based animal study. Place and Duration of Study: Physiology department, Army Medical College Rawalpindi, from Mar to Jun 2015. Methodology: This randomized controlled trial was conducted at Physiology Department Army medical college. Male healthy Sprague Dawley rats were randomly divided into 3 groups (n–15 each) i.e. control group (group I) fed with normal pellet diet (NPD), obese group (group II) and obestatin treated obese group (group III) fed with high fat diet (HFD). After 10 weeks, group III was treated with obestatin (1nmol/100ml intraperitoneally). Blood samples were obtained by terminal intracardiac sampling for bioasssays of FSH, LH, testosterone, leptin and MDA by ELISA. Results: Obestatin supplementation in obese rats showed significant increase in LH levels (3.79 ± 0.05) and testosterone levels (2.07 ± 0.22) when compared to the non treated obese rats (2.19 ± 0.07) and (1.37 ± 0.15) respectively while significant decrease in leptin (3.85 ± 0.23) and MDA levels (1.62 ± 0.07) was observed when compared to the non-treated control groups (6.10 ± 1.18) and (1.95 ± 0.07) respectively. However, serum FSH levels remained unchanged among the treated and nontreated groups. Conclusion: Obestatin increases the testosterone levels by augmenting the pituitary gonadal axis through decrease in the oxidative stress and leptin levels in obese rats.

Objectives: To observe the effect of lipid lowering by atorvastatin administrationon platelet reactivity by measuring serum beta thromboglobulin concentration in male andfemale Sprague Dawley rats. Study Design: Randomized control trial (RCT). Place of study:The study was conducted at Physiology department, Army Medical College, Rawalpindi. Animalhandling, obesity induction, drug administration and sample collection were done at NationalInstitute of Health (NIH), Islamabad and biochemical assays were performed at Centre forResearch in Experimental and Applied Medicine (CREAM), Army Medical College, Rawalpindi.Period: 12 months. Material and Methods: Ninety healthy Sprague Dawley (male and female)rats were randomly selected and divided into three equal groups. Group I rats (normal control)were given normal chow diet for three weeks. Group II rats (obese control) were given high fatdiet for three weeks to induce obesity. Group III rats (obese treated) were given atorvastatinfor three weeks in a dose of 10 mg/kg/day orally by gavage method after obesity induction.Terminal blood sampling was done at the end of the study by intra-cardiac puncture. Bloodwas centrifuged to obtain serum and serum beta thromboglobulin was measured by usingEnzyme Linked Immunosorbant assay. Results: There was a significant (p < 0.05) increasein serum B-TG concentration in obese rats as compared to normal control rats. Atorvastatinadministration to obese rats significantly (p < 0.05) reduced serum B-TG concentration.Conclusions: Obesity increases and statin administration decreases platelet reactivity in highfat diet induced obese Sprague Dawley rats as reflected by serum B-TG concentration.

BACKGROUND <br />Guava is an herbal with proven antioxidant and anti-inflammatory properties. The aim of this study was to investigate the anti-arthritic activity of the ethanol extract of Psidium gujava leaves (EEPG) against complete Freund’s adjuvant (CFA) induced arthritis in rats. <br /><br />METHODS<br />An experimental study was conducted on 40 male Wistar Sprague Dawley rats, which were divided into 5 groups. Each group was induced with 0.2 mL CFA (1 mg/mL) on day 1 and 0.1 CFA mL booster injection on day 5. Group I served as an arthritic control, group II received dexamethasone (6.75 mg.kg-1 orally), group III, IV and V received EEPG at oral doses of 250, 500, and 750 mg/kg BW, respectively, on days 14 to 28. Anti-arthritic activity was observed from the arthritis score, the paw circumference was measured on days 0, 1, 4, 8, 12, 16, 20, 24, and 28, the mobility score was determined on days 12 and 28, and the histolopathology of the knee joint was examined on day 29. <br /><br />RESULTS<br />Ethanol extract of Psidium guajava leaves significantly suppressed the swelling of the paws in chronic phase based on increasing of edema (%), while starting on day 20. EEPG at 250 mg/kg was most effective in significantly reducing arthritis scores (p&lt;0.05). Histopathological examination showed repair of the knee joint synovial membrane and cartilage.<br /> <br />CONCLUSIONS<br />Psidium guajava leaf extract is effective in decreasing the inflammatory response and arthritic symptoms in rats with adjuvant-induced arthritis. Psidium guajava leaves can be developed into an alternative anti-arthritis treatment.

Patients with collapsing glomerulopathy (CG) have marked proteinuria that rapidly progresses to chronic renal failure. In this study, we investigated if the nephropathy produced in a rat model by the injection of serum from CG patients induced alterations in fatty acid (FA) metabolism. Twenty-four female Sprague-Dawley rats were divided into four groups of six rats each: Group I, control rats (C); Group II, rats that received injections of 1 mL of 0.9% NaCl saline solution (SS); Group III, rats injected with 25 mg/mL of serum from healthy subjects (HS); and Group IV, rats injected with 25 mg/mL of serum from CG patients. In all groups, the systolic blood pressure (SBP), proteinuria, creatinine clearance (CC), cholesterol and total FA composition in the kidney and serum were evaluated. The administration of serum from CG patients to rats induced glomerular collapse, proteinuria, reduced CC and elevated SBP (p ≤ 0.01) in comparison with the C, SS and HS rats. The FA composition of the serum of rats that received the CG serum showed an increase in palmitic acid (PA) and a decrease in arachidonic acid (AA) when compared to serum from HS (p ≤ 0.02). In rats receiving the CG serum, there was also a decrease in the AA in the kidney but there was an increase in the PA in the serum and kidney (p ≤ 0.01). These results suggest that the administration of serum from CG patients to rats induces alterations in FA metabolism including changes in PA and in AA, which are precursors for the biosynthesis of the prostaglandins that are involved in the elevation of SBP and in renal injury. These changes may contribute to collapsing glomerulopathy disease.

Abstract Background Development of drug-induced hepatic damage (DIHD) during chemotherapy is the most common reason for interruption in chemotherapy. This study evaluated the hepatoprotective activity of the ethanolic extract of Tamarindus indica stem bark (EETI) against the induced DIHD in Sprague Dawley rats. Methods The rats were divided into five groups (n=5). Group I, group III, group IV, and group V rats received 1 mL 1% carboxymethyl cellulose, EETI 100 mg/kg body weight (b.wt), EETI 200 mg/kg b.wt, and silymarin 100 mg/kg b.wt, respectively, orally once every day for 28 days. After 1 h–group II, group III, group IV, and group V rats were administered with isoniazid (INH) and rifampicin (RIF) 50 mg/kg b.wt each orally once every day for 28 days. Then, 24 h after the last dosing, blood was withdrawn from the rats and analyzed for liver specific enzymes and biochemical markers. They were examined for histopathology. Results Co-administration of INH and RIF in group II significantly increased alanine transaminase, aspartate transaminase, alkaline phosphatase, lactate dehydrogenase, serum bilirubin, and cholesterol levels while reduced the total protein and albumin levels compared to that of group I. EETI in group III and group IV rats significantly restored the liver specific enzymes and biochemical markers altered due to co-administration of INH and RIF to normal in a dose-dependent manner. EETI 200 mg/kg b.wt showed better protection to liver than EETI 100 mg/kg b.wt and was comparable to silymarin 100 mg/kg b.wt. It was well supported with histopathology of liver tissues. Conclusions EETI possesses hepatoprotective activity against DIHD in rats. It may have a substantial impact on developing clinical strategies to treat patients with hepatic damage.

Objective: To compare and evaluate the effects of broiler chicken fed with commercially offered feed and chicken fed with organic diet on BMI and weight gain in Sprague Dawley rats. Study Design: A randomized controlled trial. Place and Duration of Study: Multi-Disciplinary Laboratory of Department of Biochemistry and Molecular Biology, Army Medical College, Rawalpindi, and collaborated with Quaid-e-Azam University, Islamabad from November 2017 to April 2019. Methodology: Ninety male early weaned Sprague Dawley rats were arbitrarily assorted into three groups (n=30). Group I control rats were nourished on standard pelleted diet. Group II rats were nourished with organic chicken meat along with their standard pelleted diet. Group III rats were nourished with broiler chicken meat along with their standard pelleted diet. BMI and weight gain were estimated. All variables were calculated as Mean ± SD values. One-way ANOVA was applied to determine the significance among groups followed by Tuckey’s HSD post hoc test. p value ≤ 0.05 was considered significant. Results: The current study demonstrated significant increase in BMI (p ≤ 0.001) and weight gain (p ≤ 0.001) in both experimental groups as compared to control group. Conclusion: Based on the findings of our study we propose that broiler chicken meat consumption could be the probable cause of weight imbalances and out of proportion gain of weight and growth in experimental rats.

Volume expansion inhibits the proximal reabsorption of water, bicarbonate, and chloride. The present work tested a hypothetical role of parathyroid hormone (PTH) in the expansion effect. We studied 19 Sprague-Dawley rats during a plasma-replete euvolemic state and following 10% body wt colloid-free expansion. In group I, six intact rats, volume expansion decreased plasma ionized calcium concentration ([Ca2+]P) from 2.28 +/- 0.06 to 2.11 +/- 0.04 meq/liter and increased nephrogenous cAMP (NcAMP) from 29 +/- 5 to 66 +/- 10 pmol X min-1 X g kidney wt-1. In group II, six acutely thyroparathyroidectomized (TPTX) rats, [Ca2+]P also fell from 2.18 +/- 0.08 to 1.80 +/- 0.08 meq/liter but NcAMP did not rise significantly (9 +/- 3 vs. 17 +/- 5 pmol X min-1 X g kidney wt-1). These data strongly suggest that stimulation of PTH activity occurred during expansion in intact animals. In group III, seven TPTX rats, volume expansion inhibited proximal reabsorption of total CO2 by 11%, of chloride by 24%, and of water by 19%. Volume expansion-induced reduction in bicarbonate, chloride, and water reabsorption was smaller in TPTX than in intact rats previously studied. We conclude that volume expansion inhibits proximal reabsorption in part by decreasing the active transcellular NaHCO3 and NaCl transport secondary to stimulation of PTH activity.
