| heal.abstract | Ethanol administration in rats induces liver damage and suppression of liver regeneration. To further understand the underlying mechanism, we investigated the effects of ethanol on hepatic stimulator substance (HSS) levels during liver regeneration caused by partial hepatectomy. The hepatotrophic action of HSS to ethanol-treated partially hepatectomized rats was also examined. Rats received repetitive ethanol or saline doses beginning 1 hr prior to 70% partial hepatectomy (PH), and the animals were killed at 16, 24, 32, 40, 48, and 60 hr after PH. Our results showed that ethanol inhibited hepatic regenerative capacity and prolonged liver regenerative process. HSS biological activity in ethanol-administered rats peaked at 48 hr after PH, in contrast to saline-treated ones where activity peaked at 24 hr. Additionally, exogenous HSS administration to ethanol-treated partially hepatectomized rats increased liver proliferating capacity and suppressed the elevation of serum ALT activity. These results showed that ethanol modifies the time course of HSS biological activity during the regenerating process. The observed suppression of HSS activity at 24 hr after PH was in relation with a reduction of DNA synthesis. Exogenous administration of HSS to ethanol-treated partially hepatectomized rats restored DNA synthesis and ameliorated serum AST levels, indicating that HSS could be used in the treatment of ethanol-induced hepatic failures. | en |
