Résumé
@#Objective To study the effect of Pleurotus eryngii polysaccharide on aging mice induced by D-galactose (D-gal). Methods 72 ICR mice were divided into high, moderate, and low dosages (of polysaccharide) groups, piracetam group, model group, and control group, 12 in each group. The model of aging mice was induced with D-gal. They were tested with Y-maze, and the contents of superoxide dismutase (SOD), malondialdehyde (MDA), lipofuscin and L-glutamate in cerebrum were determined 6 weeks after model. Results Compared with the model group, the achievement of Y-maze improved, the activities of SOD increased and the content of MDA and lipofuscin decreasd in high and moderate dosage groups (P<0.05), while the mass of brain and kidney increased and the L-glutamate decreased in the high dosage group (P<0.05). Conclusion Pleurotus eryngii polysaccharide can ameliorate aging of mice induced by D-gal.
