Note: DC: diene conjugates, TC: triene conjugates, SB: Schiff’s bases, CHF: chronic heart failure. Research group 1: animals received multiple exposures to H₂. Research group 2: animals received single exposure to H₂. Data are presented as mean values ± SD. * p < 0.05, vs. control group (Student’s t-test). Indicators of healthy animals (physiological norm): concentration of SB—3.012 ± 0.654 (relative unit).
