Decreased uptake of taurocholate and ouabain by hepatocytes isolated from cirrhotic rat liver
To differentiate between the “intact” and “sick” cell hypothesis explaining decreased clearance of endo‐ and xenobiotics, we measured uptake of taurocholate and ouabain in hepatocytes isolated from cirrhotic rat liver.

Summary: | To differentiate between the “intact” and “sick” cell hypothesis explaining decreased clearance of endo‐ and xenobiotics, we measured uptake of taurocholate and ouabain in hepatocytes isolated from cirrhotic rat liver. Cirrhosis was induced by chronic exposure of male Sprague‐Dawley rats to phenobarbital and carbon tetrachloride. Uptake of [14C]taurocholate and [3H]ouabain was measured by a rapid filtration technique. Hepatocytes from cirrhotic liver were as viable as control hepatocytes—as judged by trypan blue exclusion and lactate dehydrogenase release—but consumed 28% less oxygen. Vmax of both taurocholate (3.16 ± 0.95 vs. 0.40 ± 0.35 nmoles·min−1·106 cells−1; p < 0.001) and ouabain (2.16 ± 0.78 vs. 0.83 ± 0.26 nmoles·min−1·106 cells−1; p < 0.005) was significantly reduced. These results are compatible with the “sick” cell hypothesis. |
