Fig. 4. — KCl-induced contraction in pulmonary artery (A) and mesenteric artery (B) of normoxic, hypoxic, and MCT-treated rats with or without treatment with NH₄Cl (acidosis). Pulmonary and mesenteric artery rings were stimulated with 96 mM KCl, and the contractile response was measured and presented in g/mg tissue (A) or in g (B). Data represent means ± SE (n = 6–8). *Measurements in hypoxia or MCT-treated rats are significantly different (P < 0.05) from corresponding measurements in control normoxic rats. #Measurements in NH₄Cl-treated (acidosis) rats are significantly different (P < 0.05) from corresponding measurements in hypoxia or MCT-treated rats without NH₄Cl treatment. †Measurements in hypoxia+acidosis rats are significantly different (P < 0.05) from corresponding measurements in normoxia+acidosis rats.
