Relaxation responses of the pulmonary arteries to AVP. Concentration-response curves to AVP in segments of pulmonary arteries from rats (N = 5–6). The number of rats is the number of repetitions of each group. After the presence or absence of the L-NAME pretreatment, contraction was all induced with U46619, the segments were exposed to increasing concentrations of AVP except sham group. Asterisk indicates significance compared to the sham group. “*” means p < 0.05; “**” means p < 0.01; “***” means p < 0.001; The hashtag indicates the significance between the presence and absence of the L-NAME pretreatment. “#” means p < 0.05; “##” means p < 0.01 (one-way analysis of variance, Bonferroni post hoc comparison)
