Analysis of neuronal nitric oxide synthase (nNOS)-positive nerve fibers in penile dorsal nerves.
Representative graphs are presented for rats fed a normal diet and received PBS (NR+PBS), rats fed a high-fat diet and received PBS (HR+PBS), and rats fed high-fat diet and received ADSC (HR+ADSC). nNOS positive fibers are stained brown (arrows). The number of nNOS-positive nerve fibers was higher in NR+PBS and HR+ADSC than in HR+PBS. Magnification is X 400.
