Studies on Lymphoid Activity
It has been shown that resistance to transplanted cancer follows stimulation of the lymphoid tissue when the stimulation is induced by either heat or small doses of x-rays. In this paper we have attempted to determine whether the degree of immunity had a quantitative relation to the amount of the stimulation. Fortunately, the two methods at our disposal give stimulation of markedly different ch...
متن کاملStudies on Transmissible Lymphoid Leucemia of Mice
Lymphoid leucemia of the mouse is readily transmitted by intravenous inoculations. The majority of the mice inoculated successfully develop leucemic, a smaller number of them, aleucemic lymphadenosis. The data presented favor the view that leucemic and aleucemic lymphadenosis are essentially the same condition. Leucemia produced by transmission is preceded by an aleucemic stage, in which the ly...
متن کاملStudies on Characterization of the Lymphoid Target Cell for Activity of a Thymus Humoral Factor
The immune response to SRBC was measured in the spleens of adult thymectomized, total body irradiated mice injected with various combinations of thymus and bone marrow cells together with thymic humoral factor (THF). It was found that the number of plaque-forming cells was significantly increased when THF was given in vivo immediately after thymus cell administration or when thymus cells were i...
متن کاملIn Vitro Studies on Radiation Lymphoid Recovery of Mouse Spleen
In vitro studies, utilizing an organ culture method were reported on mutual interactions between irradiated spleen, normal bone marrow, and thymus. It has been shown; (a) that singly isolated spleen explants were incapable of lymphoid regeneration, (b) thymus had no stimulatory effect on spleen regeneration, (c) bone marrow interacted synergistically with spleen leading to appearance of lymphoi...
متن کاملUltramorphological and ultracytochemical studies on tubuloreticular structures in lymphoid cells.
Tubuloreticular structures that are frequently present in the cytoplasm of lymphoid cells grown in vitro were studied with cytochemical methods at high resolution. The structures are easily digested by Pronase and pepsin; they are not sensitive to trypsin or RNase. From the results obtained, we conclude that the tubuloreticular structures are of proteinaceous nature and that they are mainly com...
