Production and release of plasminogen by isolated perfused rat liver.

Imatinib metabolism and disposition in isolated rat perfused liver

Imatinib is an orally administered tyrosine kinase inhibitor which inhibits the Bcr-Abl protein-tyrosine kinase with high selectivity. Imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. The metabolism of imatinib is mediated by the cytochrome P450 (CYP) isoenzymes in the liver and gut wall. CGP74588 is a major active metabolite of ima...

The isolated perfused rat liver.

The disposition of mefloquine has been investigated in the isolated perfused rat liver (IPRL) preparation after the administration of [C]mefloquine HCI (3.8 mg, 4 1 Ci, quinoline ring labeled). Mefloquine underwent avid hepatic uptake within 10 min of dosing. Also at this point, hepatic oxygen consumption was reduced markedly in four of the six IPRL preparations, but was restored completely by ...

Synthesis and release of Hageman factor (Factor XII) by the isolated perfused rat liver.

The site of synthesis of Hageman factor (HF, Factor XII) has not been previously demonstrated with certainty. We have studied the production and release of HF in the isolated perfused rat liver and have compared rates of synthesis in this system with absolute rates of degradation measured in vivo. Rat livers, perfused for 5 h with a recycling fluid consisting of a perfluorochemical emulsion (Fl...

SEQUESTRATION OF LEUKOCYTES BY THE ISOLATED PERFUSED RAT LUNG

The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...
