【Abstract】 The radioprotective effects of pollens collected from beehive were eval-uated through the pollen feeding experiment on the irradiated mice. In experiment, mice were exposed to y-ray irradiation from 60Co with doses ranging from 700 to 800 rad and submitted subsequently to pollen feeding as compared with the controlled group supplied with ordinary diet. The results of the experiments indicated that the survivor rate of the pollen feeding group (23.3%) were much higher than that of the control group (83.3%). The damage in the cellular components in the hematopoitic tissues caused by the irradiation exhibited in lesser extent in the pollen feeding groups than the corresponding control groups, and the recovery of the cell comonents in the myeloid, spleen, thymus and the peripheral circula-tion as well as the organ weight of spleen and thymus were well promoted by the feeding of beehive pollens. The rehabilitation of the myeloid cell populations and the T-cell lymphocytes be associated instantly to the res-toration of the hematopoitic and immunological activities in the irradiated mice. Thus the radioprotective effects of the Beehive pollen demonstrated in the experiments may be conducted through the promotion or the pro-liferative activities of the cells in the hematopoitic tissues,更多还原
