Figure 4. The nNOS immunohistochemical staining of rat corpus cavernosum in NC, BIIAL, HFD, BCH and MS groups after 12 weeks.

Figure 4

Sections were made transversal to the penile axis. (A) Normal nNOS expression was observed in the NC group. (B) Moderately decreased nNOS expression was observed in the BIIAL group. (C) Mildly decreased nNOS expression was observed in the HFD group. (D) Significantly decreased nNOS expression was observed in the BCH group. (E) Similar nNOS expression was observed in the MS and NC groups.
