Figure 5

Immunohistochemical staining showing iNOS expression in control (N), GB alone (GB), CIS alone (CIS), and the three GB-protected rats (CIS+L: 50 mg/kg GB; CIS+M: 100 mg/kg GB; CIS+H: 200 mg/kg GB). Photomicrographs show variable levels of iNOS expression in different experimental groups. Brown staining indicates iNOS expression. CIS group shows increased levels of iNOS expression compared to N and the GB-protected groups. Tissues were counterstained with hematoxylin, 400x.
