Role of Ketotifen on metabolic profiles, inflammation and oxidative stress in diabetic rats.

Abstract

We aim to explore effects of Ketotifen on metabolic profiles, inflammation and oxidative stress. Sprague Dawley (SD) male rats were randomly divided into normal control group (NC) and experimental groups, and experimental group rats were fed with high-sugar and fat diet for 6 weeks. Then, experimental group rats were divided into diabetes group (DM) and ketotifen treatment group (KT). KT group was given ketotifen via Intragastric for 8 weeks with the dosage of 0.09 mg/kg/d. Fasting plasma glucose (FPG) was measured using glucose oxidase-phenol amino phenazone method. Fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were tested by enzyme-linked immunosorbent assay. Malondialdehyde (MDA) and superoxide dismutase (SOD) were quantified by spectrophotometer method. Before Ketotifen administration, compared with NC group, DM and KT groups showed significantly high levels of body weight, FPG, FINS, HOMA-IR, TC, TG, LDL, IL-6, TNF-α and MDA, and lower levels of HDL and SOD (All p <0.05). After 4 weeks of Ketotifen administration, levels of body weight, FPG, FINS, HOMA-IR, TC, TG, LDL, IL-6, TNF-α in KT group decreased significantly, and levels of HDL and SOD elevated significantly (All p <0.05). After 8 weeks of Ketotifen administration, levels of body weight, FPG, FINS, HOMA-IR, TC, TG, LDL, IL-6, TNF-α and MDA in KT group decreased more obviously, and levels of HDL and SOD elevated significantly further (All p <0.05). Ketotifen improved metabolic profiles, and ameliorated status of inflammation and oxidative stress.
