Popis: 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.
