Figure 1: Renal tissue IL-6 concentrations. LPS injection increased renal tissue IL-6 concentration, while all doses of captopril decreased it. The data are shown as mean ± SEM. **P <0.01 compared to the control, +P <0.05, ++P <0.01, and +++P <0.001 compared to LPS. IL-6: Interleukin-6, LPS: Lipopolysaccharide, SEM: Standard error of the mean.
