Effects of hypoxia (2% O2, 8 min) on PAP recorded in an in situ isolated preparation
A and B, sample recordings obtained, respectively, in a control and in a perinatally hyperoxic rat. C, mean increases in PAP under the effects of hypoxia in both groups. Data are the mean ± SD of eight and nine individual values. ***P < 0.001. D–F, effects of the NOS inhibitor NMLA (5 × 10−5 m) on the response elicited by hypoxia in a control (D) and a perinatally hyperoxic rat (E). Mean ±SD of the responses obtained in six individual values in both groups (C). *P < 0.05.
