protective effects of withania somnifera root on inflammatory markers and insulin resistance in fructose-fed rats
Authors
abstract
background: we investigated the effects of withania somnifera root (ws) on insulin resistance, tumor necrosis factor α (tnf-α), and interleukin-6 (il-6) in fructose-fed rats. methods: forty-eight wistar-albino male rats were randomly divided into four groups (n=12); group i as control, group ii as sham-treated with ws by 62.5mg/g per diet, group iii fructose-fed rats received 10%w/v fructose, and group iv fructose- and ws-fed rats. after eight weeks blood samples were collected to measure glucose, insulin, il-6, and tnf-α levels in sera. results: blood glucose, insulin, homeostasis model assessment for insulin resistance (homa-r), il-6, and tnf-α levels were all significantly greater in the fructose-fed rats than in the controls. treatment with ws significantly (p < 0.05) inhibited the fructose-induced increases in glucose, insulin, homa-r, il-6, and tnf-α. conclusion: our data suggest that ws normalizes hyperglycemia in fructose-fed rats by reducing inflammatory markers and improving insulin sensitivity.

full textThe Effects of Simvastatin on Free Fatty Acids Profile in Fructose-fed Insulin Resistant Rats
Backgrounds: Type 2 diabetes mellitus is the most common metabolic disease and free fatty acids, as signaling molecules, can play a crucial role in the development of it. Different free fatty acids, through various cell membrane receptors, induce different effects on metabolic pathways and thereby affect insulin sensitivity. Simvastatin is a cholesterol decreasing drug prescrib...

Objective(s): This study was aimed to investigate the effect of Berberis integerrima (B. integerrima) extract on insulin sensitivity in high-fructose-fed insulin-resistant rats. Materials and Methods: Experimental rats were randomly divided into two groups: the control group was fed a regular chow diet while other group fed with a high-fructose diet for 8 weeks. After the first six weeks, the a...

Withania somnifera is an important medicinal plant, which is used in traditional medicine to cure many diseases. Flavonoids were determined in the extracts of W. somnifera root (WSREt) and leaf (WSLEt). The amounts of total flavonoids found in WSREt and WSLEt were 530 and 520 mg/100 g dry weight (DW), respectively. Hypoglycaemic and hypolipidaemic effects of WSREt and WSLEt were also investigat...

This study investigated the effect of Withania somnifera Dunal (WS) root extract and diazepam in social isolation induced behavior such as anxiety and depression in rats. Rats were isolated for 6 weeks and the assessment of changed behavior were done on elevated plus maze (EPM) and forced swim test (FST). Isolation reared rats spent less time into the open arms on EPM and significantly increase...
