Abstract:
Objective To observe the effects of cyclovirobuxinum D(Cvb-D)on the myocardium cell apoptosis of myocardial ischemia rats.Methods The rats were given Cvb-D 0.55,1.1 and 2.2 mg/kg orally per day for 21 days respectively.The myocardial ischemia model was induced by isoprenaline intraperitoneal injection.Myocardium tissue was observed under light microscope and end labelling TUNEL method was used to determine the cell apoptosis.Then the average percentage of apoptosis cell was figured out to evaluate the effect of Cyb-D.Results Cvb-D obviously lightened isoprenaline-induced myocardial pathological changes such as turbulence of myocardial fiber,plasmolysis of necrotic cell,inflammatory cell infiltration of necrotic interstitial region.Cvb-D remarkably inhibited myocardium cell apoptosis of myocardial ischemia rats caused by isoprenaline.Conclusion Cvb-D has the action of ameliorating myocardium cell apoptosis caused by myocardial ischemia.
