Effect of resveratrol on peripheral blood mononuclear cells oxidative DNA damage in type 2 diabetes mellitus patients in vitro / 中国临床药理学与治疗学

ABSTRACT

AIM: To explore the oxidant-antioxidant status and levels of mononuclear cells (PBMCs) oxdative DNA damage in patients with type 2 diabetes mellitus (T2DM), and to value the effect of resveratrol on peripheral blood mononuclear cells oxidative DNA damage in T2DM patients in vitro. METHODS: The DNA damages in PBMCs of 39 T2DM patients with vascular complication, and 29 T2DM patients without complication were detected by single cell gel electrophoresis (the comet percentage). The levels of plasma total antioxidative capacity (TAC), the contents of plasma malondialdehyde (MDA) and plasma thiol group (SH) were measured. The effect of resveratrol on DNA damage of T2DM patients were investigated in vitro. In addition, 26 healthy subjects were studied as a control group. RESULTS: The comet percentage of PBMCs and the contents of plasma MDA in T2DM patients without complication were all significantly higher than that in healthy controls (P
