Although studies in isolated hepatocytes have demonstrated that hypoxia adversely affects drug conjugation, the impact of hypoxia on drug elimination by conjugation in the intact liver has not been defined. This study in the isolated perfused rat liver examines the effect of acute hypoxia on the
Livers from fasted (N = 16) and fed (N = 22) rats were perfused with harmol (50 microM) for an initial 30 min with normal oxygen delivery (6-10 mumol/min/g liver), then for 45 min with perfusate equilibrated with O2/N2 mixtures, which reduced hepatic oxygen delivery to 0.9-6 mumol/min/g liver, and
In isolated hepatocytes the availability of intracellular glucose appears to be a key factor controlling the rate of xenobiotic glucuronidation during hypoxia. This study in the isolated perfused rat liver examines the effect of both a 24-hr fast and removal of glucose (8 mM) from liver perfusate on
