Ceramide mechanism of anti-myocardial ischemia/reperfusion injury of effective position in Sini Decoction / 中成药

ABSTRACT

AIM: To study the effects of Sini Decoction's effective component(SNDE) on myocardial apoptosis and ceramide content during myocardial ischemla/reperfusion. METHODS: The mice of Kunming species were randomly divided into 3 groups control,myocardial ischemia/reperfusion and SNDE.After inducing myocardial ischemia/reperfusion injury of mice in vivo with pituitrin(Pit),myocardial SOD activity and MDA content were measured.DNA agarose gel electrophoresis and fluorescent stain of DAPI were done to check up apoptosis.The content of myocardial ceramide(?g/kg) was measured through HPTLC and scan of thin plate. RESULTS: The myocardium of model group has the phenomenon of DNA ladder.The apoptosis index and the ceramide content in model group were higher than those of control group(P
