| Purpose Vildagliptin has been shown to prevent microvascular complications during diabetes. The aim of this research was to
evaluate the antioxidant effects of vildagliptin in diabetic nephropathy.
Methods The diabetes was induced in the animals by high-fat diet and intraperitoneal injection of 35 mg/kg streptozotocin. After
diagnosis of diabetes, the vildagliptin (6 mg/kg/day) was orally administered for one month. The biochemical parameters of
blood urea nitrogen, creatinine, insulin, and serum albumin were measured. The levels of stress oxidative markers were detected
using spectrophotometry.
Results Treatment with vildagliptin significantly diminished blood glucose, oxidative stress, and reduced creatinine as well as
increased insulin secretion. In addition, the vildagliptin improved renal glomerular and tubule interstitial damages and reduced
vascular lesions.
Conclusions The treatment with vildagliptin can be useful in controlling the renal complications of type 2 diabetes mellitus
through inhibiting lipid peroxidation and increasing the antioxidant enzymes. |
