Protective effect of curcumin in fructose-induced metabolic syndrome and in streptozotocin-induced diabetes in rats
The aim of this study was to investigate the effect of pre-treatment with curcumin on metabolic changes induced by two different pathophysiological mechanisms in rats (fructose diet and streptozotocin (STZ)-induced diabetes mellitus).
Five groups with 10 rats per group were investigated: control group (healthy rats), fructose diet groups without any pre-treatment (FD), fructose diet groups with curcumin pre-treatment (FDC), STZ-induced diabetes mellitus without any pre-treatment (SID) and STZ-induced diabetes mellitus with curcumin pre-treatment (SIDC). Systolic blood pressure, and several metabolic and oxidative stress parameters were assessed.
Systolic blood pressure significantly increased in all groups compared with control group (P
The pre-treatment with curcumin in our experimental models significantly improved metabolic (total cholesterol, triglycerides, AST and ALT) as well as oxidative stress parameters (MDA, NOx, and Thiol) in both fructose diet and in STZ-induced diabetes in rats. These properties of curcumin may serve to improve the metabolic and oxidative stress conditions in patients with these pathological features.
