[Studies on the functional ability of swine liver perfused with human blood in machine recirculation attempt. 2. Behavior of serochemical parameters].
In the present paper is reported on the behavior of different serochemical parameters in heterologous perfusion of the liver of pigs. The perfusion of the animal livers was carried out with preserved human blood in 11 recirculation experiments (closed machine circulations). In addition to this an empty circulation with human blood without attachment to an animal liver was carried out, whereby otherwise the arrangement of the experiment was the same, in order to take into consideration the effects of the blood traumatisation in the interpretation of the results. The enzymes GOT and LAP proved as sensible indicators of the lesion of the liver cells occurring in the perfusion of the liver of the pigs. The behavior of the mitochondrial GDH as well as of the lysosomal enzymes SP and BETA-GC which scarcely increased during the recirculations in the perfusate blood, however, allows the conclusion that there did not appear a severe lesion of the liver cells (necrobiosis) during several hours of perfusion. A cholestasis did not develop during the perfusions, when one takes as basis the behavior of the enzymes AP, GGTP and AAP indicating cholestasis. Compared with GOT the enzyme GPT showed by far less elevations in the perfusate blood so that with increasing duration of the perfusion the De-Ritis-quotient significantly increased. Increased LDH-activities above all revealed the increasing during perfusion haemolysis and less reliably a lesion of the liver of the pig. The increase of ADA  in the perfusate blood proved as nearly exclusively conditioned by haemolysis. Total protein, albumins, immunoglobulins, cholinesterase and thymol turbidity test remained unchanged in the course of the perfusions.
