Rajtar G. and Kleinrok Z.: Effect of chronic ethanol treatment and the abstinence period on the ethanol elimination by isolated rat liver lesioned by carbon terachloride Acta Physiol. Pol. The study was carried out on perfused livers isolated from rats receiving ethanol (EtOH) as their only drinking fluid for the period of 4 weeks. Twelve, 24, 72 and 120 hours after EtOH withdrawal the livers were isolated and perfused with 100 ml of perfusion mixture with addition of EtOH (0.2% final concentration). After 12 hours of EtOH withdrawal acceleration of the EtOH elimination from perfusate was observed. It returned to the control level after 24 hours, but after 72 and 120 hours of abstinence the rate of EtOH elimination from perfusate was found to diminish. CC1₄ injected to the rats in doses of 2 and 5 mmoles/kg once a week for the period of 4 or 8 weeks, resulted in decreased EtOH elimination from the perfusate. In the EtOH-drinking group previously treated with CC1₄ we found that irrespective of the time of EtOH withdrawal, EtOH elimination did not differ from that in the respective CC1₄ treated group, only 12 hours after its withdrawal EtOH elimination was decreased in livers injured with CC1₄ in dose of 5 mmoles/kg.
