    Streszczenie angielskie: Effect of cadmium administration (3 mg CdCl2/kg body weight i.p.) and/or whole-body irradiation (3 Gy of gamma rays) on the rat brain was studied in the course of 21 d after treatment. The effect was studied on the basis of quantitative analyses of DNA and RNA. It was found that the changes of nucleic acids in the brain hemispheres were very slight and they lay in a temporal drease in DNA content on the 7th - 14th d after the irradiation alone and in combination with cadmium (CdCl2 administered 30 min before irradiation). In the cerebellum, the changes of nucleic acids were profound than in the hemispheres. The decrease in DNA content in the cerebellum was also only temporal and it occurred on the 1st d after the irradiation alone. The most interesting finding seems to be increase in DNA content in the cerebellun in a later period after the irradiation alone and in combination with cadmium without concomitant increase in RNA content. This finding suggests increasing number of cells with high nucleoplasmic ratio (mainly of cadmium administration on the rat brain was less expressed than effect of irradiation and combibation of the two treatments did not induce any summation effect.
