[Structural and functional characteristics of bush-like interoceptors in the initial period of anoxia].
The bush-like receptors of the Rana temporaria urinary bladder have been studied electrophysiologically, cytophotometrically and electronmicroscopically. A combined morpho-physiological experiment demonstrates a phase character in dynamics of the spontaneous impulsive receptor activity, no changes in the terminal plate size. heterogeneity of the reaction for methylene blue. The receptor plates have been cytophotometrically demonstrated to take a longer time for staining and bleaching; that can serve as a structural index on a decreasing energy level of metabolism. Certain changes and rearrangement in the receptors plate organelles take place. A suggestion is made that the receptors studied possess some labile enzymatic systems owing to which the metabolism level can be swiftly and profoundly changed.
