title: [Comparative radioautographic evaluation of RNA synthesis in vivo and in biopsy material].
abstract: The liver, kidney, skin biopsies are able to incorporate actively 3H-uridine, and the maximum rate of RNA synthesis over the hepatocyte nuclei in the peripheral zone of the biopsies corresponds to relevant rates in vivo. Only the skin biopsies were distinguished by total cell labelling. Liver, renal, skin capillary endotheliocytes can serve intertissue marker of the diffusion depth of 3H-uridine.
