Figure 7: Renal tissue CAT activity. LPS injection decreased renal tissue CAT activity, while the medium and the highest doses of captopril increased it. The data are shown as mean ± SEM. ***P <0.001 compared to the control, +P <0.05 and +++P <0.001 compared to LPS, $$$P <0.001 compared to 10 mg/kg captopril, &P <0.05 compared to 50 mg/kg captopril. CAT: Catalase, LPS: Lipopolysaccharide, SEM: Standard error of the mean.
