ABSTRACT
AIM:
To observe the effect of Shenmai injection,a chinese medicine,on apoptosis of cardiac myocytes after hypoxia.METHODS:
Cardiac myocytes were separated from neonate rat heart and cultivated in vitro.Hypoxia condition was induced by mixture of 95%N2 and 5%CO2.Cells were exposed to hypoxia for 6 h or 12 h and treated with Shenmai injection(5 mL/L) from 24 h before hypoxia until the end of hypoxia.First,apoptosis was detected with Annexin V-FITC and PI staining by flowcytometry.Then,the activity of cardiac myocyte mitochondria was observed by MTT method.Mitochondria membrane potential and the activity of caspase 3,7 were also measured by laser scan microscopy and multi-detection microplate reader,respectively.RESULTS:
The apoptotic cells became more and more with prolonged hypoxia.Shenmai injection enhanced mitochondria activity,kept membrane potential,inhibited the activation of caspase3,7 and then decreased apoptotic cells(P
