[Tissue receptor reaction to transient anoxia in the absence of glucose]

Under conditions of anoxia for 15 min and at glucose absence in the incubation medium, the frog urinary bladder receptors loose their ability to generation of spikes much quickly, than under the same conditions, but in glucose presence. Sorption of vital dye (methylene blue) by the terminals sharply decrease up to a complete their inability to be stained. After glucose is injected, this ability is partly restored. Ability of mitochondria to contrasting with usual electron microscopical contrast media is also noted to change.
