| 1 | Effect of Bushenyisui Formula on brain tissue apoptosis and Bcl-2 in beta-amyloid protein-induced Alzheimer's disease rat models显示文摘OBJECTIVE:To investigate the effect of Bushenyisui Formula on cell apoptosis and positive B cell lymphoma(Bcl-2) in the Brain of rat models of Alzheimer's disease(AD) induced by beta-amyloid protein(Aβ) and the mechanism underlying the effect.METHODS:Total of 40 SD rats,20 females and 20 males,were randomly assigned to 4 groups,controlled group(A),model group(B),conventional treatment group(C) and Bushenyisui Formula treatment(BYFT) group(D),10 rats in each group.Aβ 1-42 was injected into the bilateral hippocampus of the rats in group B,C and D to create the models of AD.Sham operation was performed on the rats of group A in the same way by injecting equal volume of 0.9% sodium chloride solution into their bilateral hippocampus.5 days after operation,Bushenyisui Formula was intraperitoneally administered at a dose of 450 mg/kg to the rats of group D(QD) for 20 days.Equalvolumeof0.9%sodiumchloridesolution wasintraperitoneallyinjectedintotheratsofgroupB withthesameprocedure.C suspension(20 mg/mL) was intraperitoneally injected into the rats of group B with the same procedure.The number of apoptotic cells in Brain and the positive Bcl-2 were counted.The changes of learning and memory abilities were evaluated usingY-maze.RESULTS:Right after the establishment of the models,group B,C and D compared to group A respectively,the outcomes of Y-maze were significantly different from that of group A,which suggested obvious learning and memory disorder in those groups(P<0.01).After treatment,the times of electronic shocks of group C and D were significantly less than that of group B(P<0.05),and the numbers of apoptotic cells and positive Bcl-2 were significantly different from those of group B,apoptotic sells' number of group C and D smaller than that of group B and the number of positive Bcl-2 greater than that of group B.CONCLUSION:Bushenyisui Formula could increase the number of Bcl-2 in brain,which improved the function of nervous system pertaining to learning and memory abilities. | Shuke Cui Yan Sun Chengzang Liu | 2012 | Journal of Traditional Chinese Medicine2012，32，4： | 6 |
