title: [Radiomodifying effect of serotonin on the cells of the hematopoietic system].
abstract: Mice were injected with serotonin (0.5 and 2.0 mg/mouse) 15 min before and immediately after irradiation (4.5 and 7.0 Gy). With the preparation administered prior to irradiation one could observe an increase in the quantity of CFUc survived (endo- and exo-test), acceleration of restoration of cellularity (in the bone marrow) and growth of the spleen weight. The acceleration of restoration of the bone-marrow cellularity was also noted when serotonin was administered after irradiation. The post-irradiation effect of serotonin was also detected in cells in vitro. It is concluded that the radiomodifying effect of serotonin on the haemopoietic system is due to a decrease in the number of damaged cells and increase in the rate of reproduction of intact cells.
