Figure 2. Quercetin attenuated cardiomyocyte apoptosis.

(A) Representative images of the TUNEL assay (n = 5). Significant differences were observed between trauma vs. sham and trauma vs. trauma + quercetin. Quercetin was used at 20 mg/kg i.p. 0.5 h before trauma. (B) The apoptotic index was calculated by counting TUNEL signals in 5 randomly selected crypts after TUNEL staining, as in A. Statistical comparisons were performed using one-way analysis of variance. **P < 0.01 vs. sham; ^##P < 0.01 vs. trauma.
