Figure 3. Leakage of necroenzyme creatine kinase (CK) and lactate dehydrogenase (LDH) after skeletal muscle ischemia-reperfusion (IR) injury of 3 h of ischemia and 24 h of reperfusion (n=36). A, Serum CK activity. B, Serum LDH activity. Data are reported as means±SD. ^⋆P<0.05, ^★P<0.01 vs sham-operated control group (C); ^▾P<0.01 vs IR group (one-way ANOVA).
