Abstract

Nitric oxide(NO) play an important role in normal and pathophysiological cells including as a messenger molecule, neurotransmitter, microbiocidal agent, or dilator of blood vessels and artheriosclerosis, hypertension, myocardial infarction, respectively. To investigate that Ondamtang in the potential contribution of the levels of nitric oxide generated by endothelial nitric oxide synthase (eNOS) and the mechanisms of protection against L-NAME, human ECV304 cells, which normally do not express eNOS, were expressed by L-NAME. L-NAME stimulated rat or cells were found to be resistant to injury and delayed death following the Ondam-tang. Inhibition of nitric oxide synthesis abolished the protective effect against L-NAME, thrombin and collagen exposure. Interestingly, such effects have bee observed during stimulation with agents such as KCl on L-NAME mediate rats, were damaged by the NOS inhibitor NG-nitro-L-arginine methyl ester (L-NAME). Cardiovascular diseases is one of the blood vessels and renin-angiotensin system dynfunction. So we studied on herbal medicine that have a relation of vessels endothelium necrosis. In Oriental Medicine, Ondam-tang has been used for disease in relation to cardiovascular system. We studied on the protection and inhibitory effects of cardiovascular diseases in L-NAME induced rat or ECV304 cell lines through the Cell morphological pattern, Tunel assay, LDH activity, heart rate, blood pressure and immunohistochemistric analysis by Ondam-tang. As the result of this study, In group, the anti-apoptosis and necrosis in the cardiovascular system have a potential capacity for prevented, protected and treating the diseases of cardiovascular system, against the necrosis of rat and ECV304 cells with eNOS and calpain expression by L-NAME is promoted.
