Abstract:
Objective:To investigate the immunologic effect of probiotic FGM fermented astragalus membranaceus on brain damage mice.Methods:Astragalus membranaceus was fermented by probiotic FGM,and ethanol subsiding method was used to extract fermented astragalus polysaccharide in fermented astragalus powder.Fermented astragalus polysaccharide 200,100,50 mg/(kg · d) were intraperitoneal injected daily for 7 consecutive days.The brain damage mice model was established at 1 h after the last dose via suture ligation.Spleen index,thymus index were determined by gravimetric method.The proliferation of splenic lymphocytes was determined by MMT method.Enzyme linked immunosorbent assay(ELISA) was used to determine tumor necrosis factor α(TNF-α) and interleukin 1β(IL-1β).Results:Compared with model group,the spleen index and thymus index was significantly increased in fermented astragalus polysaccharide high concentration administration group (P < 0.05).Splenic lymphocyte proliferation was significantly increased (P<0.05).The content of TNF-α and IL-1 β decreased significantly(P<0.05).Conclusion:Probiotic FGM fermented astragalus polysaccharide has immune protective effect on brain damage mice.
