Objective:To investigate the molecular mechanism of Bushenyiqi Formula(BSYQ) on the apoptosis in Corticosterone damaged Rat thymocytes.Methods:Prepared the BSYQ contained rat serum.Thymocytes were divided into 3 groups:control group;model group;BSYQ group.The effect of apoptosis was measured by Annexin V-FITC/PI double staining and FCM.The expression of bcl-2,bax,Il-2 were measured by Real-time PCR and Western Blotting.Results:10-5 M corticosterone induced apoptosis of thymocytes,up-regulated the expression...
