eNOS immunohistochemistry in the kidney tissues of different experimental groups (×400). The eNOS immunoreactivity was characteristically cytoplasmic and the cytoplasm was stained brown color (arrow), (a) control normotensive group moderate immunoreactivity. (b) L-NAME group showing very weak immunopositive reaction. (c) L-NAME + lisinopril group (10 mg/kg) showing moderate immunoreactivity. (d) L-NAME + Roselle-Olive (500 mg/kg) group showing strong immunoreactivity. (e) L-NAME + Roselle-Olive (250 mg/kg) group showing strong immunoreactivity. (f) L-NAME + Roselle-Olive (125 mg/kg) group showing moderate immunoreactivity. (g) Bar chart represents the eNOS immunopositivity expressed as area %. Mean values with different superscripts are significantly different ().
