The dry ginger rhizome was extracted with ethyl acetate, and gingerol content was enriched by liquid-liquid extraction. The extract was analyzed for the percentage of 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol by HPLC. The acute toxicity was evaluated as per OECD guidelines 423. Ginger extract was fed at 2000 mg/kg body weight to overnight fasted female rats (8-10 weeks old; 160-180 g). The animals were observed daily for clinical signs of abnormality/mortality. After 14 days, animals were sacrificed, and gross pathological changes were recorded. Sub-acute toxicity of ginger extract was studied by feeding the extract at 100, 500, and 1000 mg/kg daily to rats as per OECD guidelines 407. The total gingerols content in the purified viscous extract was 36-43%. The finished formulation of ginger extract used for the toxicity studies had 8% total gingerols. In the acute toxicity study, no mortality or clinical signs of toxicity were observed at a maximum recommended dose level of 2000 mg/kg; therefore, the LD50 is >2000 mg/kg in rats. The repeated administration of...

Objective: To evaluate the effect of some counterfeit anti-obesity drugs that are not licensed by the Ministry of Health. Materials and Methods: 100 male rats were divided into 10 groups. The first group received a normal diet for two months. The second group received a high-fat diet (HFD) for two months; the third group received HFD for one month then returned to a normal diet. The remaining seven groups received HFD for one month then treated with Orlistat, Turbo slim (dose 1), Turbo slim (dose 2), African mango (dose1), African mango (dose 2), Slim factor (dose 1), and Slim factor (dose 2) respectively for an additional one month. Bodyweight, glucose, insulin, leptin, adiponectin, MCP-1, reduced glutathione, MDA, lipid profile, kidney, and liver functions were measured. Adipose tissue index, atherosclerosis index, HOMA-IR, and QUICKI were calculated. Results: Feeding with HFD induced a significant increase in body weight as well as insulin resistance, serum lipids, serum leptin, plasma MCP-1, and tissue MDA and a significant decrease in serum adiponectin and tissue...

Urolithiasis is the most prevalent urinary tract disorder in males. Alfuzosin is a selective antagonist of post-synaptic α1a adrenoceptor, causing relaxation of smooth muscle in the bladder and prostate, which results in an improvement of urine flow and prevents ureter stones. The present study was aimed to evaluate the effectiveness of Alfuzosin on rats as a preventive and curative agent against the development of urolithiasis. Urolithiasis was induced by oral administration of 0.75% v/v ethylene glycol and 2% w/v ammonium chloride in drinking water for 15 days in rats. Ethylene glycol feeding resulted in hyperoxaluria and a significant (p<0.001) increased in urinary calcium, phosphate, and serum creatinine, uric acid levels. By oral administration of Alfuzosin at the dose of 1 mg/kg and 2 mg/kg for 15 days as a preventive regimen and from 8th day to 15th day as a curative regimen, significantly (P<0.01) reduced the calcium, phosphate, creatinine and uric acid levels in rats. The histopathological studies showed the disrupted renal parenchyma, degenerative changes in glomeruli, calcification in...

Introduction: Vernonia arborea, belonging to the Asteraceae family, found in the Western Ghats of India and Sri Lanka, was traditionally used in wound healing. It is proven that some of the plants of this genus have anti-diabetic properties. e.g., V. amygdalina. So this study was done to screen and to evaluate the anti-diabetic potency of the leaf extract of Vernonia arborea in diabetic Zebrafish models. Materials and Methods: Extraction was done by cold percolation method. The toxicity of the extract was evaluated, and the concentrations of 25 mg/l and 50 mg/l of tank water were taken for treatment as higher concentrations were found to be toxic. The Zefrafish were divided into the respective control and treatment groups. The different groups were induced with diabetes by high-glucose feed for 30 days. The standard group was treated with metformin and the test groups with the chosen concentrations of the extract for 7 days. The blood glucose level was checked on alternate days for 7 days. On the 7th day, the liver...

The present study is designed to investigate the hepatoprotective effect of Hydrilla verticillata on lead-induced hepatic damage in freshwater fish. The fish were treated with a sub-lethal concentration of lead acetate to induce liver damage and fed with supplementary feed containing 20% of hydrilla dry powder. After 21 days of treatment, the liver was removed, and hepatotoxicity and its prevention were analyzed. Liver marker enzymes like alanine transaminase (ALT), aspartate transaminase (AST), acid phosphatase (ACP) were measured and compared with the control. Histopathological study of the liver was done to find out the protective effect of Hydrilla verticillata. The lead-induced hepatotoxicity by stimulation of ALT, AST, ACP and represented by degeneration of hepatocytes and formation of cytoplasmic vacuoles. Hydrilla verticillata supplementation significantly (p ˂ 0.05) reduced the level of hepatic enzymes and showed a protective effect on hepatocytes by normalization of degenerated and fibrotic liver tissue as of control. This study strongly confirms the hepatoprotective effect of Hydrilla verticillata against lead-induced acute liver toxicity. Hydrilla verticillata could be recommended...
