Abstract
The author indicates the blood picture changes by means of average values that have been found with 20 rats after undergoing fractionated short-time irradiations of the whole body of doses that amounted to 50 r five tlmes, and were applied within 14 days. The special sensibility of the eosinophil leucocytes, even towards fractionated irradiation, is stressed. The results show that the recuperation factor grows with increasing total irradiation periods. It must be assumed that while irradiation is in progress, regenerating and regressive changes are parallelly occurring in the hematopoietic tissue. Even in the case of an organism under the stress of irradiation, ACTH leads to a new fall in eosinophils while there is no such fall in lymphycytes. (auth)
