[Autoradiographic analysis of RNA synthesis by sympathetic neurocytes from a population depleted of nerve cells].

Autoradiographic analysis of the changes of the nuclear and cytoplasmic RNA in the sympathetic neurocytes of presenile mice subjected to partial desympathization during the first days after birth by guanetidine injections was carried out. As compared with the control mice of the same age, neurocytes of the populations with a sharply reduced number of cells were characterized by a slower migration rate of the newly-synthesizing RNA from the nucleus to the cytoplasm. The neurocytes of partially desympathized infantile, young and presenile mice were not larger than those of the control mice.
