[Study of RNA and protein synthesis in mollusc epithelial tissues adapting to changes in the salinity of the medium].
RNA and protein synthesis in the epithelial tissues of White Sea snails Mytilus edulis was investigated autoradiographically with H-3-uridine and S-35-methionine during adaptation to various salinities (10 0/00, 14 0/00, 18 0/00, 35 0/00); normal salinity being 25 0/00. The incorporation of labelled precursors into the epithelial tissues of M. edulis was shown first to change abruptly, the return to the normal condition occurring after a prolonged adaptation. The reaction of different tissues shows specific features. The role of compensatory processes during the adaptation to changed salinities, is discussed.
