Title: [Structuro-functional changes in bushy interoceptors during protracted anoxia]. Author: Lukashin VG, Vshivtseva VV. Journal: Arkh Anat Gistol Embriol; 1985 Jul; 89(7):18-24. PubMed ID: 2413828. Abstract: The bushy receptors of the frog urinary bladder respond to the effect of 60-minute-long anoxia with a complex combination of morphological. tinctorial and electrophysiological reactions. A biphase change in dynamics of bioelectrical activity takes place (an initial increase of frequency with its successive decrease), prolongation of the vital staining periods with methylene blue, change in the character of staining and decoloration of the receptory plates: increase in homogeneity and in intensity of staining, discontinuance of granuloformation and weakening of processes of the plates mobility. The ultrastructural changes are mainly concerned with mitochondria, where either crists reduce and osmiophility decreases, or increases. A part of mitochondria does not change. Certain heterogeneity in reactive changes of the receptors is noted. This is considered as manifestation of functional heterogeneity of the receptory units and their structural elements.[Abstract] [Full Text] [Related] [New Search]
