[The thymus structure during radiation exposure in antenatal ontogeny].
Peculiarities of thymus morphogenesis were studied in mice subjected to irradiation in antenatal ontogenesis by means of anatomic, histological and morphometric methods. Dosed action of X-ray irradiation up to 25 cGy in sum and stress factors were established not to impair sharply embryonal thymus morphogenesis but is accompanied with reactive reorganization in the organ. Dosed irradiation over 25 cGy in sum caused prognostically unfavourable disturbances of embryonal thymus morphogenesis manifested as hyperplastic and degenerative dystrophy changes.
