Краткое описание

This study investigates the oral hypoglycemic activity of Pleurotus ostreatus (P.o.) and P. cystidiosus (P.c.) mushrooms on normal and alloxan-induced diabetic Wistar rats. Different doses (250, 500, 750, 1000, and 1250 mg/kg/body weight) of suspensions of freeze-dried and powdered (SFDP) P.o. and P.c. were administered to normal rats, and postprandial serum glucose levels were measured. Optimal time of activity was investigated using the dose 500 mg/kg. Hypoglycemic effect of a single dose of SFDP P.o. and P.c. (500 mg/kg) were investigated using diabetic male and female rats at different stages of estrous cycle and compared with metformin and glibenclamide. Chronic hypoglycemic activity of SFDP P.o. and P.c. (500 mg/kg) was studied using serum glucose levels and glycosylated hemoglobin levels. Maximally effective dose of SFDP P.o. and P.c. was 500 mg/kg. The highest reduction in the serum glucose level was observed 120 minutes after administration of mushrooms. A single dose of P.o. and P.c. significantly (P < 0.05) reduced the serum glucose levels of male diabetic rats. The hypoglycemic activity in female rats was highest in proestrous stage. The hypoglycemic effect of P.o. and P.c. is comparable with metformin and glibenclamide. Daily single administrations of P.o. and P.c. to diabetic rats exert apparent control on the homeostasis of blood glucose. SFDP P.o. and P.c. possessed marked and significant oral hypoglycemic activity. This study suggests the consumption of P.o. and P.c. mushrooms might bring health benefits to mankind as it shows hypoglycemic activity in rats.
