[Ovarian morphology during experimental blastomogenesis in the cerebellum]

A morphological and histochemical study of the ovaries in 79 rats with cerebellar blastomogenesis due to DMBA in comparison with the ovaries of intact rats, rats with trauma of the cerebellum, rats with a paraffin pill implanted into the cerebellum, as well as with the ovaries of rats with a chemical cancerogenesis of the intestine, permitted to claim, that the most characteristic changes of the ovaries in cerebellar blastomogenesis consist in reduced amount of premordial follicules, athresia of the growing follicles and a formation of multiple follicular cysts. These processes are underlain by destruction of premordial follicles and a degeneration of the ovule in the growing follicles.
