Abstract
Aqueous spleen extracts were purified using acetone precipitation, membrane filtration, affinity chromatography, and dialysis. These extracts were able to inhibit thymidine incorporation into lymphoid cells (MKT-CH and PHA-stimulated lymphocyte cultures). They did not influence non lymphoid tissues (melanoma cells Mel Ei 78 and Ehrlich ascites cells). The inhibition was reversible and the purified extracts were not cytotoxic. The extracts correspond to a chalone. Their importance for prevention of graft versus host reaction and for treatment of lymphoproliferative diseases is discussed. Wäßrige Extrakte aus Kalbsmilz wurden durch Azetonfällung, Membranfiltration, Affinitätschromatographie und Dialyse gereinigt. Diese Extrakte hemmten den Thymidineinbau in lymphoiden Zellen (MKT-CH und PHA-stimulierte Lymphocytenkulturen). Zellen nicht lymphatischen Gewebes (Melanomzellen Mel Ei 78 und Ehrlich-Ascites-Zellen) wurden nicht beeinflußt. Die Hemmung war reversibel, und die Reinextrakte wirkten nicht zytotoxisch. Die Extrakte entsprechen einem Chalon. Ihre mögliche Bedeutung für die Verhinderung der Graft versus host reaction und für die Behandlung lymphoproliferativer Erkrankungen wird diskutiert.Keywords
