title: Generation of factor VIII coagulant activity by isolated, perfused neonatal pig livers and adult rat livers.
abstract: Isolated, normal, neonatal pig livers released VIII:C into perfusates of porcine von Willebrand blood lacking VIIIR:AG and VIII:RWF. Neonatal von Willebrand livers released VIII:C only when partially purified VIIIR:AG was added to the von Willbrand blood. Adult rat livers, perfused with frozen-thawed erythrocytes suspended in Tyrode's solution containing 6% bovine serum albumin and hence no VIIIR:AG released VIII:C only when serum, adsorbed serum or cryoprecipitate from rat plasma was added to the perfusate. Cycloheximide blocked the release of VIII:C from rat liver.
