[Quantitative distribution of nucleolar nucleic acids in the Purkinje cells during vestibular stimulation and immobilization of rats].

The content of nucleic acids in the nucleoli of Purkinje cells was studied under horizontal rotation and immobilization of rats by UV cytophotometry. The histograms of the distribution of nucleolar nucleic acids under both exposures have a common trend towards asymmetry. Unlike the immobilized animals, the rats subjected to rotation show in all the time points a correlation between changes in the total content of nucleic acids in the nucleoli and cytoplasm, and an alteration in the asymmetry of distribution of nucleolar nucleic acids. The changes in the distribution of the latter acids and cytoplasmic RNA under vestibular stimulation are also in good agreement as regards the time and pattern.
