title: [Effects of vitamin E and vitamin C on nonenzymatic glycation and peroxidation in experimental diabetic rats].
abstract: SD rats were peritoneally injected with streptozotocin (STZ) to establish diabetic animal model. The changes of nonenzymatic glycation and peroxidation in rats supplemented with vitamin C and/or vitamin E during five weeks were investigated. It was found that the glycated hemoglobin, glycated LDL, renal cortical AGEs and MDA in sera and renal cortex significantly decreased after supplementation of vitamins E and C jointly. It was also observed that the MDA in serum and the cortex of kidney but not glycated hemoglobin, glycated LDL and AGEs significantly decreased in the groups supplemented with vitamin C or vitamin E separately. The results suggested that joint supplementation of vitamin C and vitamin E could inhibit nonenzymatic glycation obviously and peroxidation in diabetic rats and protect the kidney from damage under hyperglycemia.
