Zusammenfassung

Untersucht wurde die Entstehung von sekundärer Amyloidose bei röntgenbestrahlten Mäusen. Die Röntgenbestrahlung verursachte in der Milz, weniger ausgesprochen in der Leber und in den Nieren Parenchymdegeneration, sowie bei fortgesetzter Bestrahlung auch Milznekrosen. Als diese Mäuse zusätzlich subcutane Kaseinatinjektionen erhielten, starben viele; außerdem konnte bereits Ende der ersten Woche nach Beginn der Injektionen Amyloid in der Milz, in geringerem Grade auch in der Leber und den Nieren beobachtet werden. Das Amyloid schien sich in den gleichen Gebieten abzulagern, in denen die Röntgenbestrahlung Nekrosen hervorgerufen hatte. Bei Mäusen mit Kaseinatinjektionen ohne Röntgenbestrahlung entwickelte sich eine Amyloidose bei etwa der Hälfte der Tiere, aber frühestens nach 3 Wochen, die Schwere der Amyloidose war durchschnittlich geringer als bei röntgenbestrahlten Mäusen.

Summary

The development of secondary amyloidosis following x-ray irradiation of mice was studied. The x-irradiation caused parenchymal degeneration in the spleen, less intense in the liver and kidneys. With continued irradiation splenic necroses occurred. When the mice were given in addition subcutaneous injections of casein many died, and by the end of the first week after the initial injection amyloid was observed in the slpeen, less extensively in the liver and kidneys. The amyloid appeared to have been deposited in the same regions in which the x-irradiation had produced necroses. An amyloidosis developed in about 1/2 of the mice receiving casein injections without x-irradiation, but at the earliest after three weeks. The degree of the amyloidosis was on the average less than in the x-irradiated mice.
