Summary
In a period of 24–120 h after the irradiation of rats with x-rays in a dose of 700R there is a marked nuclear polymorphism. In the corneal epithelium there appear cells with satellite nuclei and a larger number of binuclear cells. The results of investigations carried out by means of cytospectrophotometry showed that after irradiation the number of polyploid nuclei containing DNA in quantities of 5–8 respectively grows 30% whereas normally it is only 10%. The satellite nuclei contain an insiginficant amount of DNA, which points to their formation from chromosome fragments during atypical karyokinesis. The amount of DNA in the nuclei of binuclear cells varies extensively; the minimum quantity being 1n+1n, the maximum we have noted being 3n+5n.
