Protective Effect of Polysaccharides from Inonotus obliquus on Streptozotocin-Induced Diabetic Symptoms and Their Potential Mechanisms in Rats

الملخص EN

The present study aimed to evaluate the therapeutic effects of polysaccharides from Inonotus obliquus (PIO) on streptozotocin- (STZ-) induced diabetic symptoms and their potential mechanisms.

The effect of PIO on body weight, blood glucose, damaged pancreatic β -cells, oxidative stresses, proinflammatory cytokines, and glucose metabolizing enzymes in liver was studied.

The results show that administration of PIO can restore abnormal oxidative indices near normal levels.

The STZ-damaged pancreatic β -cells of the rats were partly recovered gradually after the mice were administered with PIO 6 weeks later.

Therefore, we may assume that PIO is effective in the protection of STZ-induced diabetic rats and PIO may be of use as antihyperglycemic agent.
