Table 3.

Apoptotic index (AI) values between the groups

	Apoptotic index (%)
	Day 4	Day 8
Group I (Control Group)	0±0	0±0
Group II (Cisplatin group)	4.16±0.40a	9.50±0.83ab
Group III (Cisplatin + Cortexin group)	3.66±0.51a	2.25 ± 0.50ac

The variables were expressed as mean±standard deviation.

^aCompared to the control group, a significant level of apoptosis was present in Cisplatin and Cisplatin+Cortexin groups on the 4^th and the 8^th days of the study (p<0.05).

^bAI values recorded on the 8^th day was significantly higher compared to the values on 4^th day in Cisplatin group (p<0.05).

^cWhen Cisplatin+Cortexin and Cisplatin groups were compared for Day 8 values, a significant decrease was found in Cisplatin+Cortexin group (p<0.05)
