Figure 5. — Immunohistochemical staining for iNOS in testis samples. iNOS expression in the (A) control, (B) 20 mg/kg cimetidine, (C) 40 mg/kg cimetidine and (D) 120 mg/kg cimetidine groups (counterstain with Mayer's hematoxylin; magnification, ×400; scale bar, 50 µm). Compared with that in the control group (no expression), the amount of cells expressing iNOS was increased in all cimetidine treatment groups, including the 20, 40 and 120 mg/kg groups (arrows). iNOS, inducible nitric oxide synthase.
