Objective:To investigate the effects of Panaxadiol Saponins(PDS) on the nitric oxide(NO) and nitric oxide synthase(NOS) in serum in acute myocardial infarction(AMI) dogs.Methods:An AMI model was made by ligating left coronary artery in dogs.The content of NO and activity of NOS in serum were detected by spectrophotometric method.N-BT staining method was used to delermin the extent of myocardial infarction and the change in myocardial ultrastructure was observed by transmission electron microscope.Results: Compared with model group
PDS increase the content of NO and activity of NOS in serum.and decrease the extent of myocardial infarction significantly.PDS can alleviate the change induced by ischemia in myocardial ultrastructure markedly.Conclusions: PDS has apparently protective effects on myocardium in acute myocardial infarction dogs.Its mechanisms probably liein increasing NO and NOS level in serum.
