title: [Labelling of the nuclei of differentiated Purkinje neurons after 3H-thymidine administration to rats].
abstract: Incorporation of 3H-thymidine into Purkinje's cells of the cerebellum of rats aged 6, 10, 12, 15 and 30 days has been demonstrated. As regards the distribution of silver granules, the nuclei can be divided into two groups--with a local label in the nucleolic zone or in the extranucleolic chromatin and with a uniform labeling. The nuclei with an intense uniform label are encountered rarely, i.e. 1-2 nuclei per 10000 cells. The frequency of the nuclei with local labeling of the nucleolus is higher than that with an extranucleolic local label. In 12--30-day-old rats, the number of labeled nuclei exceeded that in 6--10-day-old animals.
