초록

Effects of endothelin-l (ET-l) on contraction, $Ca^{2＋}$ transient and L -type $Ca^{2＋}$ current ( $I_{Ca,L}$) were investigated in single ventricular myocytes isolated from guinea-pig hearts. ET-l at concentrations of 5 and 10 nM produced a biphasic pattern of inotropism： a first decrease in contraction by 34.4$\pm$2.5 ％ of the control followed by a sustained increase in contraction by 66.6$\pm$8.4% (mean$\pm$S.E.M., n=9).(omitted)
