Chronic diabetes mellitus (DM) can cause liver dysfunction and other complications. As Humulus japonicus is known to have anti-inflammatory and antioxidative effects, we sought to evaluate the hepatoprotective effect of H. japonicus extract (HJE) on a DM model. HJE reduced aspartate aminotransferase, alanine aminotransferase, and direct bilirubin levels and restored albumin activities relative to those found in the DM model. The abnormal levels of triglyceride, total cholesterol, high-density lipoprotein, and low-density lipoprotein in DM returned to normal levels after HJE treatment. DM-induced inflammation of the liver was ameliorated by HJE through reduction of tumor necrosis factor-α, interleukin-1β, and cyclooxygenase-2 levels. HJE treatment downregulated malondialdehyde levels that were increased by DM. However, the downregulated superoxide dismutase and glutathione levels in DM were increased by HJE. Histological studies showed that HJE improves the liver tissue damage caused by DM. Collectively, our findings suggest that HJE may improve liver damage in DM and exhibit an inhibitory effect on hepatic injury through its anti-inflammatory and antioxidative actions.
