[Autoradiographic analysis of transcription in sympathetic neurocyte nuclei following axonal injury].

One of the trunks of the inner carotid nerve of the cranial cervical sympathetic ganglion of the rabbit was intersected. The level of transcription in nervous cells at the height of the development of the morphological signs of the axonal reaction was determined by autoradiography. The method is based on the demonstration of the activity of RNA polymerases. Injury of the process causes a considerable decrease in the total and nucleoplasmic labeling of the nuclei of retrogradely changed neurocytes. The level of nucleolar labeling was not changed.
