    Notes: Summary Lymphocytes and plasma cells have been demonstrated in the peripheral zones of lobules in liver biopsies from patients suffering from chronic aggressive hepatitis. In the region of contact between lymphocytes and parenchymal cells, the cell membranes are frequently not demonstrable so that an impression is created of cytoplasmic fusion. However, when the goniometer is used, the cell membranes in this region can still be demonstrated at a certain tilt angle. It can therefore be concluded that the presumed cytoplasmic fusions are frequently the result of superposition effects in projection.

    Description / Table of Contents: Zusammenfassung Es wurde bei 11 Schweinen eine orthotope Xenotransplantation der Hundeleber durchgeführt. Die Überlebensdauer war durchschnittlich 4,3 ± 1,5 Std. Die Todesursachen waren generalisierte Blutungen. Um die hyperakute Abstoßungsreaktion zu bremsen, wurden vor der Verpflanzung der Hundeleber bei 5 Fällen Hundeniere und Hundemilz je 20 min und bei 5 anderen Fällen eine zweite Hundeleber am Femoralkreislauf eingeschaltet. Wegen der stark aufgetretenen Kreislaufreaktion (Tachykardie und Hypotonie) war die Überlebensdauer noch kürzer. Aus gleichen Gründen wurden hohe Dosen Prednisolon intraund postoperativ bei 5 Fällen verabreicht. Die Überlebensdauer von 4 Schweinen war 9,0 :L 2,2 Std. Ein Schwein überlebte 5 Tage. Bei diesem Schwein wurde Hundeproteinsynthese beobachtet.
    Notes: Summary Orthotopic xeno-transplantations of dog livers into 11 pigs were carried out. The survival time was on average 4.3 ± 1.5 h. The cause of death was generalized haemorrhage. To inhibit the hyperacute rejection, before trans-planting the dog liver we connected dog kidneys and dog spleens in 5 cases and in another 5 cases a second dog liver to the femoral circulation, 20 min, before the transplant, in each case. In view of the very strong circulatory reaction (tachycardia and hypotension) the survival time was even shorter. For the same reason high doses of prednisolone were administered intra- and postoperatively in 5 cases. The survival time of 4 pigs was 9.0 ± 2.2 h. One pig survived for 5 days, and in this animal we were able to observe dog-protein synthesis.

    Notes: Summary 1. 11 orthotopic xenotransplantations of canine liver to pig were carried out. The survival time was 4.3 ± 1.5 hrs. The death occured because of general bleeding. 2. To stop the hyperacute rejection high dosage of prednisolon was given intraand postoperativ in 5 cases. 4 recipients survived 9 ± 2.2 hrs and 1 of them 5 days. It is partly possible to stop the hyperacute rejection of xenografts dog-to-pig with high dosage of prednisolon.
