Effect of Pleurotus ostreatus on hyperglycemia, DNA damage and chromosomes aberrations

摘要

One of the main health problems with high and markedly increased complications is diabetes. Despite several projects with preventative strategies and armories of medication, the arrangement of diabetes remains grossly unsatisfactory. Thus, it is vital to identify unfamiliar drugs or novel nutraceuticals for treating and preventing diabetes without side effects. The present study deals with scientific information on mushrooms with regards to its potential use as anti-diabetic active food. In addition to the anti-hyperglycemic action of mushrooms, the present study presents its effect on DNA damage, chromosome aberrations and sperm alternations in streptozotocin-induced diabetic rats. These animals have been treated, for 30 days, with amaryl (as control treatment) (0.03 mg/kg·b·wt/dl), low-dose mushroom (100 mg/kg·b·wt/dl) and high-dose mushroom (200 mg/ kg·b·wt/dl). The glucose level GL of streptozotocin-induced diabetic animals has been markedly improved by mushroom treatment; for example GL has decreases from 167.6 mg/dl down to 116.0 mg/dl for treatment with high-dose mushroom and 128.9 mg/dl for treatment with low-dose mushroom, comparing with amaryl treatment that decreases GL down to 92.6 mg/dl. But, the experimental results show that treatment with mushroom is better than treatment with amaryl in case of genetic changes (DNA fragmentation, disappear of some base pairs and chromosome aberrations. So, it is proposed that more close scientific attention be paid to precede more research of functional mushrooms for preventive and curative treatments for diabetes.
