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.

Asparagus africanus Lam. is a plant used traditionally to treat different ailments. Currently, scanty information is available on its safety. The aim of this study is to determine the acute toxicity of the methanolic extract on vital organs and its associated biochemical parameters. Fifteen female Sprague-Dawley rats were divided into five groups. Group I served as normal control, groups II, III, IV, and V were orally administered single dose of crude extract dissolved in distilled water at 5 mg/kg BW, 50 mg/kg BW, 300 mg/kg BW and 2,000 mg/kg BW. Rats were observed for 14 days and body weights were recorded. On day 15, the rats were sacrificed and blood samples were collected for biochemical and haematological analyses, while the liver and kidneys were sampled for histopathological examination. Body weight and haematology parameters results showed significance difference (p < 0.05) among means of HGB, RDW, RBC, and MCHC; likewise, (p < 0.001) for WBC and platelet among treated groups. Histopathology result showed that kidneys appeared normal while livers were congested with mildly swollen hepatocytes and occasional binucleation. Focal lobular hepatitis was observed in all treated animals. However, hepatic enzymes were not significantly affected and no histopathological harmful effects were observed in kidney. In conclusion, methanolic extracts of A. africanus are safe up to 2,000 mg/kg BW. The obtained results could be used as a justification for the traditional application of the plant for treatment of various ailments.

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: Adhesion formation after hepatectomy creates problems for repeat hepatectomy. This study aimed to compare the effectiveness of a spray (AdSpray) and sheet adhesion barrier (Seprafilm) in a rat hepatectomy-induced adhesion model.Methods: Thirty male Sprague-Dawley rats underwent partial resection of the left lateral liver lobe. They were randomly assigned to control (n=10), AdSpray (n=10), and Seprafilm groups. Seven days after surgery, the animals were sacrificed, and adhesions at the hepatic resection surface were blindly evaluated.Results: In the control group, adhesions were formed in all 10 animals (100%), with a 69% adhesion extent (mean). In the AdSpray group, the incidence of adhesions (40%) and the adhesion extent (mean, 10%) were significantly lower than in the control group. In the Seprafilm group, the adhesion extent (mean, 30%) was significantly lower than in the control group. As for histopathological examination, animals in the AdSpray group showed a similar healing profile to that of the control group without delayed healing and regeneration of mesothelial cells. In contrast, the Seprafilm group showed ongoing foreign body reaction to Seprafilm, and regeneration of mesothelial cells was immature at 7 days.Conclusions: Both the spray-type gel and sheet adhesion barriers significantly reduced adhesion formation after hepatectomy. The spray-type adhesion barrier caused no adverse events and induced favorable healing. These adhesion barriers may be effective in hepatectomy.

AbstractThe aim of this study is to evaluate the protective effect of ethanol extract of Aerva lanata (EEAL) in preventing acetaminophen induced liver toxicity. EEAL was prepared and its hepatoprotective effect was studied in both isolated primary hepatocytes in vitro and in Sprague Dawley rats in vivo. For in vivo studies, the animals were grouped as Group I – Control; Group II – ACN (2 g/kg b.w.); Group III – EEAL (50 mg/kg b.w.) + ACN (2 g/kg b.w.), Group IV – EEAL (100 mg/kg b.w.) + ACN (2 g/kg b.w.). Extracellular activities of the enzymes liver aminotransferease (GOT, GPT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in isolated hepatocytes and rat plasma were studied colorimetrically. Expression of GST, Nrf2, COX 1 & COX2 genes in rat liver were evaluated by RT-PCR. The results showed that ACN induced down-regulation of Nrf2 and upregulation of GST gene expression, which were modulated by EEAL treatment. GOT, GPT, ALP and LDH levels were found to be lowered in both hepatocyte culture media and plasma following EEAL treatment. In addition, the medium GOT and GPT levels were diminished following EEAL treatment only. Moreover, only ALP and LDH in serum appeared to be at normal level following EEAL treatment, whereas GOT and GPT showed levels lower than control. ACN treatment increased the expression of pro-inflammatory COX 1 and COX 2 genes and the levels of these genes were reduced by EEAL treatment. EEAL pre-treated rats exposed to ACN were found to retain normal hepatic structure compared to ACN alone treated rats. From these results it can be concluded that ethanol extract of A. lanata possesses both anti-inflammatory and hepatoprotective activity.

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.

Background. The aim of the study was to analyse the effect of caffeic acid phenethyl ester (CAPE) on fluoxetine-induced hepatotoxicity in rats.Materials and Methods. Group I served as control. Group II received CAPE intraperitoneally. Group III received fluoxetine per orally. Group IV received fluoxetine and CAPE. The total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), and liver enzymes including paraoxonase-1 (PON-1), aspartate transaminase, and alanine transaminase levels were measured. Liver tissues were processed histopathologically for evaluation of liver injury and to validate the serum enzyme levels.Results. An increase in TOS and OSI and a decrease in TAC and PON-1 levels in serum and liver tissues of Group III were observed compared to Groups I and II. After treatment with CAPE, the level of TOS and OSI decreased while TAC and PON-1 increased in serum and liver in Group IV. Histopathological examination of the liver revealed hepatic injury after fluoxetine treatment and reduction of injury with CAPE treatment.Conclusion. Our results suggested that CAPE treatment provided protection against fluoxetine toxicity. Following CAPE treatment with fluoxetine-induced hepatotoxicity, TOS and OSI levels decreased, whereas PON-1 and TAC increased in the serum and liver.
