Antidiabetic effect of polysaccharides from Pleurotus ostreatus in streptozotocin-induced diabetic rats

This study was performed to evaluate the effects of total polysaccharides extracted from Pleurotus ostreatus on type 2 diabetes. Rats were administered with high-fat diet and streptozotocin (STZ) to induce diabetes. The rats were then treated with 100, 200, and 400 mg/kg/d POP or vehicle for 4 weeks. Our experiments indicated that POP reduces hyperglycemia and hyperlipidemia levels, improves insulin resistance, and increases glycogen storage by...
