Rats were treated without or with ketamine for 1, 2 and 3 months. The corpus cavernosum of penis was immunostained with iNOS. A. Representative images of the corpus cavernosum in each group. Original magnification ×400. B. Ratio of iNOS-positive cells within the corpora cavernosa in the four groups. There was a significant increase in the iNOS expression in ketamine treated 1 and 2 months groups (p < 0.001 and 0.05, respectively) compared with the control group. #p < 0.05 versus control group; *p < 0.001 versus other groups.
