Experimental study on effect of chlorogenic acid on oxidative stress of kidney in diabetic rats / 中国综合临床

ABSTRACT

Objective To investigate the effect of Chlorogenic acid on oxidative and antioxidative system of kidney in diabetic rats.Methods 36 rats were randomly divided into three groupsnormal group(N group),diabetes mellitus group(DM group)and diabetes group treated with chlorogenic acid(CA group).Ten weeks later,blood glu-cose,weight of body and kidney ,the activity of superoxide dismutase(SOD)and glutathione peroxidase(GSH-PX)lipidperoxidation(MDA),urinary albumin excretory rate(UARE)in renal tissue were measured.Results The levels of blood glucose were not significantly different between DM group and CA group,but the weight of rats and kid-ney and the activity of SOD and GSH-PX in CA group were higher than DM group,and MDA and UAER of CA group were lower(P<0.05 for each).Conclusion Chlorogenic acid effective in improving the antioxidativity,inhibiting oxidative stress and decreasing urinary albumin.
