THE REACTION OF MONO AND BINUCLEATE CELLS OF THE SUPERIOR CERVICAL SYMPATHETIC GANGLION OF THE RABBIT TO THE REMOVAL OF THE CONTRALATERAL GANGLION,
Abstract
Binucleate nerve cells are characterized in comparison with mononucleate cells by an increased content of RNA and dense substances in the cytoplasm and of RNA + DNA and total protein in the nuclei. Surgical extirpation of one of the superior cervical sympathetic ganglia of the rabbit causes an increase in the number of binucleate cells in the contralateral ganglion. The above-mentioned increase in the quantity of neurons with 2 nuclei coincides with changes in the RNA content (increased by about 20%) and dense substances (approximately doubled) in the cytoplasm of mononucleate cells of the ganglion being investigated in which case the direction of these changes testifies to the fact that the ganglionic elements of the corresponding node are operating under conditions of increased functional load. The experimental action undertaken by us evoked characteristic changes in the quantity of nucleic acids and dense substances in the cytoplasm and nuclei not only of the mononucleate but also of the binucleate neurons. The results of this investigation demonstrate the exceptional value of quantitative cytochemical methods for solving problems concerning the functional significance of binucleate nerve cells.
