To the question of reticuloendotheliosis

Abstract

The division of leukemias, which existed until recently, or according to the latest terminology of leukemia, into two groups - lymphadenoses and myeloses, respectively, two genera of leicopoietic tissue according to the doctrine of dualists, has undergone significant changes in recent years due to the desire of a number of authors to delimit monocytes from the lymphatic and myeloid series in the form of a third independent type of blood cell elements. The works of Gold man n'a, Aschoff'a, Kiyono, Landau, Mac Nee and others put forward the doctrine of the reticuloendothelial system, the cells of which are attributed to a number of common properties: the ability to deposit electronegative colloidal substances in themselves, the ability to phagocytosis, and the participation of cells of this systems, both in embryonic and in subsequent life, especially under pathological conditions, in blood formation. Aschoff's research. Kiuono, Paschkis'a and others have shown that blood monocytes are in close genetic relationship with histiocytes of the r.-e. systems.
