TUNEL staining of apoptosis. There was no abnormal apoptosis detected in group a at any of the time points. TUNEL staining showed gradual increases in apoptosis in both groups b and c, especially group c. The rate of apoptosis in group b was significantly higher than that in group a at each time point, and it was significantly higher in group c compared with both groups a and b at each time point. (* compared with group a, p < 0.05; and # compared with group b, P < 0.05. The red arrow shows the TUNEL-positive cells)
