Table 2. Apoptotıc ındex of the experımental groups.

Group name	Control (n=6)	BEV (n=6)	IR (n=6)
Mean apoptotic index % (TUNEL [+] cells/total cells) ±SEM	0.018±0.004	0.243±0.203	0.647±0.212

The comparison of apoptotic indices of control, bev and IR groups. Among the groups that were manipulated IR group has higher apoptotic index compared to the BEV group. This is an indication showing the probable neuroprotective effect of bevacizumab. The statistical difference between all groups is significant; between C and IR p<0.001, C and BEV p<0.01 and IR and BEV p<0.01.
