The proliferation activity of the rat thymocytes after partial hepatectomy. 1980

L Desser-Wiest, and H Desser

The influence of partial hepatectomy, unilateral nephrectomy and shamoperation on thymocyte proliferation capacity in male rats was investigated. The wet weight and the cell number declines significantly after partial hepatectomy. A stimulation of mitotic activity and H3TdR incorporation on day 3 to day 6 was also observed in partially hepatectomized animals. The polyamine content of the thymocytes was transiently decreased 2 days post partial hepatectomy and shamoperation. Thereafter the amine concentrations increased and remained elevated in the case of partially hedatectomized animals. No significant changes in the content of histamine were observed.

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.
