Core Tip

Core tip: Pair-feeding was performed with control or ethanol liquid diet for 28 d in sham-operated (Sham) and partial hepatectomy (PH) rats. In PH rats, ethanol induced hepatic steatosis with liver dysfunction and higher residual blood ethanol concentrations without up-regulation of hepatic class-1 alcohol dehydrogenase (Adh1) gene expression, which was present in the Sham-ethanol rats. One week after PH, liver weight, function, and lipid metabolism-related gene expressions recovered; but Adh1 gene expression did not. Desensitization to post-hepatectomy ethanol treatment and the slow recovery of Adh1 expression from PH enhanced the susceptibility to ethanol-induced hepatic steatosis in the rats post PH.
