Abstract
Activation of macrophages-induced by lipopolysaccharide (LPS) is accompanied by the production of reactive oxygen species and inflammatory cytokines to induce hepatic injury. Renin–angiotensin system may play a role in liver damage. In the current study, the effect of captopril on the injury of inflammation-induced liver was investigated. The rats were divided into (1) Control, (2) LPS, and (3–5) LPS as well as 10, 50, or 100 mg/kg captopril for 2 weeks. Captopril decreased NO metabolites, IL-6, and MDA, while it increased CAT, SOD, and total thiol in the liver. Captopril also attenuated AST, ALT, and ALK-P, whereas it increased albumin and total protein in serum. As an ACE inhibitor, captopril improved liver function and attenuated inflammation and oxidative stress induced by LPS injection.
