Figure 1.
Cell apoptosis rate in the I/R group and normal group. (a, b) The AV/PI assay showed that the cell apoptosis rate was higher in the I/R group than in the normal group. Comparison between groups was determined by t-test. Results are shown as means ± standard deviations. P < 0.05 was considered significant; **P < 0.01. I/R, ischemia/reperfusion; AV/PI, annexin V apoptosis detection with propidium iodide.
