THE ROLE OF DIRECT OR DISTANCE EFFECT OF X-RAY TREATMENT IN THE RESPONSE REACTION OF AN ORGANISM (in Russian)
The effects of direct and indirect irradiation on cornea epithelium during mitosis were studied. The experiments were carried out with 2 and 3 months old white mice exposed to whole-body and screened head irradiations of 600 and 800 r. Data showed that the irradiation depressed the mitotic division of cornea cells. With whole-body exposure the depression begins during the irradiation: the 800 r dose completely depressed the mitotic division of cornea cells after 6 hours and with 600 r only separate single units of mitosis were observed. The depression of mitotic activity in cornea epithelium of screened head irradiation had two peak maxima, one after 2 hours and the second after 10 hours. Hence, a different mechanism in direct and indirect exposures is indicated. (R.V.J.)
