Table 2. Survival time of mice treated with free or liposomal EPI at a dose of 6 or 9/kg.

Group	Median survival time SD	ILS%	N
Control	47	-	8
Free EPI 6 mg/kg	49	3	8
Free EPI 9 mg/kg	16	−66	8
Liposomal EPI 6 mg/kg	56	19	7
Liposomal EPI 9 mg/kg	68*	45	7

N – number of mice per group, *p<0.05 as compared to the results for mice treated with 9 mg/kg free EPI (Kruskal-Wallis multiple comparison test). ILS – Increased Life Span.
