Effects of G. verum pretreatment on the level of cardiac prooxidants. (a) Comparison within and between groups in the value of O₂ ⁻, (b) comparison within and between groups in the value of H₂O₂, (c) comparison within and between groups in the value of NO₂ ⁻, and (d) comparison within and between groups in the value of TBARS. ^∗Statistical significance at the level of p < 0.05 within the control group; ^#statistical significance at the level of p < 0.05 within the G. verum group; ^¶statistical significance at the level of p < 0.05 between the control and G. verum group. Data are presented as means ± SE. R1, first minute of reperfusion. R7, last minute of reperfusion.
