Semiquantitative evaluation of tubular histological lesions

The grading system used for classifying tubular lesions is described under Material and Methods. Data are mean ± S.E.M. Histopathological classification is described under Materials and Methods.

Group	n	Histopathological Classification						Average Score
Group	n			0	+1	+2	+3	Average Score
Control	7	6	1	0	0	0.1 ± 0.1
Cisplatin	7	0	0	2	5	2.7 ± 0.2^a
Cisplatin + Ed (1)	7	0	1	3	3	2.3 ± 0.3^a, ^b
Cisplatin + Ed (5)	7	0	3	3	1	1.7 ± 0.3^a, ^b

Ed (1), edarabone 1 mg/kg; Ed (5), edarabone 5 mg/kg.
↵ ^a P < 0.05 versus control group
↵ ^b P < 0.05 versus cisplatin group
