    Abstract:
    Recently much attention has been paid to the circulatory disturbance and peripheral vascular damage in patients with sepsis and septic shock. We intended to elucidate the interaction between nitric oxide (NO) and endothelin (ET)-1 under various pathological conditions by measuring the concentrations of NO3-, the principal metabolite of NO and immunoreactive ET-1. In cases with good prognosis after the septic shock, ET-1 was significantly higher as compared with these in sepsis without shock. In lethal cases with septic shock, these parameters were abnormally high as compared with the survived case. These levels elevated as the degree of severity progressed. When patients recovered from the septic shock, plasma ET-1 levels rapidly decreased. These results may mean that the level of the concentration of ET-1 plays a key role for prevention of the multiple organ failure even after the recovery from septic shock. The elevated level of NO3- during the initial several days in septic shock will mean that NO is acting to prevent platelet aggregation and to keep blood flow by dilating the arteries during septic shock. On the contrary, it may also be suggested that the elevated level of NO3- and ET-1 leads to the dysfunction of vascular endothelial cells and the apoptosis.
