[Influence of ionizing radiation on the formation of chondrocranium in merino-sheep. II (author's transl)].
The influence of ionizing radiation on the formation of chondrocranium in merino-sheep was studied on the 28th, 29th and 30th day of fetus development following the exposition of 250 R. On the 28th day, after the radiation, delayed growth of fetus head was evoked. From the whole of chondrocranium, it was found that only lamina basalis and membranous parts of nasal and optical capsules were developed. On the 29th and 30th day after radiation, a prolonged period of development of chondrocranium was noticed. The greatest changes were seen in capsula nasalis and otica. In all the three groups some abnormal findings were found on the bases of the eyes.
