Abstract
We studied the distribution of endogenous peroxidase in the spleen of swine by modifications of the Graham and Karnovsky diaminobenzidine procedure. There is a peroxidatic activity in the majority of the ellipsoid cells (cells of the sheathed capillaries of Schweigger-Seidel), which is localized in the endoplasmic reticulum and the perinuclear cisterna. This staining is inhibited completely by aminotriazole and is rapidly destroyed even by low concentrations of glutaraldehyde. Furthermore, the reaction is abolished after boiling of tissue sections or in the absence of H2O2. The macrophages of the red pulp and a minority of the ellipsoid cells are peroxidase negative. Our results are discussed in respect to some recent studies on the system of mononuclear phagocytes. It is suggested, that the enzyme active ellipsoid cells represent a special form of macrophages, enzyme histochemically related to Kupffer cells and resident peritoneal macrophages. The enzyme negative cells of the ellipsoids are probably fibroblasts. Die Verteilung von Peroxidase-Aktivitäten in der Milz des Hausschweines wurde mit verschiedenen Modifikationen der Diaminobenzidin-Methode nach Graham und Karnovsky untersucht. Der größere Teil der Hülsenzellen der Schweigger-Seidelschen Kapillarhülsen besitzt Peroxidase-Aktivität im endoplasmatischen Reticulum und im perinukleären Raum. In den Makrophagen der roten Pulpa und in einem kleineren Teil der Hülsenzellen war diese Enzymaktivität nicht nachzuweisen. Die Befunde werden mit den bekannten enzymhistochemischen Eigenschaften der Makrophagen des Systems mononukleärer Phagozyten verglichen. Die Stellung der peroxidasepositiven Hülsenzellen im System mononukleärer Phagozyten wird diskutiert.This publication has 64 references indexed in Scilit:
