[Effect of thymocyte autotransplantation on postradiation regeneration of hematopoiesis]. 1975

M I Fedotova, and Iu I Zimin

Experiments were conducted on Wistar rats irradiated in a dose of 400 R; a study was made of the effect of thymocyte autotransplantation (4-10(8)--8-10(8)) on the restoration of cell number of the bone marrow and the spleen. There was revealed a significant stimulating effect of autotransplantation of thymocytes on the erythroid and granulocytic series in the bone marrow and on the lymphoid one in the spleen during the restoration (the 5 th-- 7 th days) after the irradiation. Irradiation of the thymocyte suspension with gamma-rays in a dose of 10 000 R failed to prevent the effect of autotransplantation on the bone marrow, but decreased its stimulating effect. A conclusion was drawn on the interaction of the administered thymocytes with the stem hemopoietic cell.

D011833	Radiation Injuries, Experimental	Experimentally produced harmful effects of ionizing or non-ionizing RADIATION in CHORDATA animals.	Experimental Radiation Injuries,Injuries, Experimental Radiation,Experimental Radiation Injury,Radiation Injury, Experimental
D003037	Cobalt Radioisotopes	Unstable isotopes of cobalt that decay or disintegrate emitting radiation. Co atoms with atomic weights of 54-64, except 59, are radioactive cobalt isotopes.	Radioisotopes, Cobalt
D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.

D006410	Hematopoiesis	The development and formation of various types of BLOOD CELLS. Hematopoiesis can take place in the BONE MARROW (medullary) or outside the bone marrow (HEMATOPOIESIS, EXTRAMEDULLARY).	Hematopoiesis, Medullary,Haematopoiesis,Medullary Hematopoiesis
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
