Influence of ET-1 on different segments of the pulmonary circulation in the IPL. a Influence of 20 nM ET-1 on the pulmonary arterial pressure (PPA): (○) control (n = 6); (●) ET-1 20 nM (n = 7); b Influence of 20 nM ET-1 on the left atrial pressure (PLA): (○) control (n = 6); (●) ET-1 20 nM (n = 7); c Influence of 20 nM ET-1 on the precapillary resistance (Rpre): (○) control (n = 6); (●) ET-1 20 nM (n = 7); d Influence of 20 nM ET-1 on the postcapillary resistance (Rpost): (○) control (n = 6); (●) ET-1 20 nM (n = 7). a-d) Statistics was performed by a LMM. P <0.05 are considered as significant: * p <0.05, ** p <0.01 and *** p <0.001
