Abstract: |
(Abstract〕 Objective To observe the effect of different treatments in TCM on myocyte apop
tosis and expression of Bcl-2 and Bax and the content of oxygen free radicals in myocardial is
chemia reperfusion in rats. Method The rats models in vivo of atherosclerosis myocardial ischemia
reperfusion were stablished, the apoptosis index (AI) was detected withTUNEL method in situ
end method, the apoptosis related genes Bcl-2Chain and Bax protein expression with avidin-bi
otin -enzyme complex (SABC) immunohistochemical method, and the activity of superox
ide dismutase (SOD) and the content of malondialdehyde (MDA) with routine method. Results
Compared with I/R group, all the treatments in TCM could reduce AI and remove effectively the
oxygen free radicals (P<0.01),the activating blood and resolving phlegm methods could二、luce
the content of MDA and increase the activity of SOD and decrease Bax expression (P<0.01),
and then, protect 1/R cardiac muscle. Conclusion The different treatments in TCM can restrain
the apoptosis of I/R cardiac muscle cells and[()protect consequently the I/R cardiac muscle. |
