Non-enzymatic and enzymatic antioxidants in ischemic and reperfused (I/R) muscle: (a) non-protein –SH levels; (b) CAT activity; (c) SOD activity. (a) The non-protein –SH levels are expressed in nmol of SH per mg of protein; (b) the CAT activity is expressed in μmol H₂O₂ per min per mg of protein; (c) the SOD activity is expressed in units of absorbance per mg of protein. Data are expressed as mean ± SE (n = 5) and were analyzed by anova, followed by Duncan's test when appropriate. Differences were considered significant when P ≤ 0.05. Significant differences are marked as a or b.
