Abstract:
AIM:To evaluate attenuating properties of N-acetylcysteine (NAC) on oxidative stress and liver pathology in rats with non-alcoholic steatohepatitis (NASH). METHODS:Male Sprague-Dawley rats were randomly divided into three groups. Group 1 (control, n=8) was free accessed to regular dry rat chow (RC) for 6 wk. Group 2 (NASH, n=8) was fed with 100% fat diet for 6 wk. Group 3 (NASH+NAC(20), n=9) was fed with 100% fat diet plus 20 mg/kg per day of NAC orally for 6 wk. All rats were sacrificed to collect blood and liver samples at the end of the study. RESULTS:The levels of total glutathione (GSH) and hepatic malondialdehyde (MDA) were increased significantly in the NASH group as compared with the control group (GSH; 2066.7+/-93.2 vs 1337.5+/-31.5 micromol/L and MDA; 209.9+/-43.9 vs 3.8+/-1.7 micromol/g protein, respectively, P<0.05). Liver histopathology from group 2 showed moderate to severe macrovesicular steatosis, hepatocyte ballooning, and necroinflammation. NAC treatment improved the level of GSH (1394.8+/-81.2 micromol/L, P<0.05), it did not affect MDA (150.1+/-27.0 micromol/g protein), but led to a decrease in fat deposition and necroinflammation. CONCLUSION:NAC treatment could attenuate oxidative stress and improve liver histology in rats with NASH.
