Nonenzymatic antioxidants in the right ventricle (RV) and brain of rats with monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH). A The glutathione (GSH)/glutathione disulfide (GSSG) ratio in the RV; B sulfhydryl (SH) group levels in the RV; C the GSH/GSSG ratio in the brain; D SH levels in the brain. Data are expressed as the mean ± standard deviation (n = 8). *P < 0.05 vs control; ***P < 0.001 vs control
