| Abstract: | AIM To investigate the antioxidant effect of polysaccharide from Dendrobium huoshanense on lens tissues of diabetic cataract rats.METHODS Rats treated with intraperitoneal injection of streptozotocin were set as the animal model of diabetic cataract.The contents of GSH,MDA and carbonyl protein were tested and the enzyme activities of GSH-PX,GR,GST,CAT and SOD were determined.RESULTS The experiment showed Dendrobium huoshanense polysaccharide could increase the content of GSH in lens and enhance the enzyme activities of GSH-PX,GR,GST,SOD and CAT,at the same time decrease contents of MDA and the protein degradation markedly on the diabetic rats.CONCLUSION The development of diabetic cataract is prevented by the polysaccharide of Dendrobium huoshanense possibly through the amelioration of oxidative stress. |
