Hypoxic pulmonary vasoconstriction recorded in anaesthetized rats perinatally exposed to hyperoxia and fed with an antioxidant diet
A, sample recording in a hyperoxic supplemented rat. B, mean pulmonary arterial pressure in normoxia (air), in hypoxia (10% O2) and during recovery (air, R) in hyperoxic supplemented rats. C, ΔPAP induced by hypoxia in control and hyperoxic supplemented rats (data for control group are the same as those plotted in Fig. 6E). D, systemic arterial pressure in rats of the three groups (control, hyperoxic and hyperoxic supplemented animals) recorded when breathing air or 10% O2. Data are the mean ± SD of 12–13 individual values. *P < 0.05; **P < 0.01; ***P < 0.001 vs. normoxia.
