title: [Mechanism of a universal supravital reaction of varicose changes of neurites].
abstract: By means of vital phase-contrast microscopy in neurites, proteolitically isolated from the neural system in representatives of 6 types of invertebrates inhabiting the White Sea and various Chordata, a comparative histological investigation has been performed to study certain reactions of varicose deformities. Solutions of the medium with a decreased ionic strength, prolonged survival etc. have been used as irritants producing varicosities. This reaction, considered to be universal, is absent in thick and gigantic fibres. It develops, first of all, in fine preterminal neurites of any localization and does not depend on the level of the animal's organization and its neural system. In the mechanism on varicosity formation, appearance of the hydrated peripheral fraction of neuroplasm is essentially important. This process is more general and is observed in all neurites.
