[Participation of calcium ions in carotid chemoreception].
The changes in calcium accumulation ability of glomus cells membranes under the action of alkaloids, acids and effector stimuli have been studied by fluorimetric chelate probe technique. The reception of these stimuli causes calcium-ions release mainly from the intracellular organoids membranes (mitochondrial and endoplasmatic). These data suggest that calcium-ions act as a messenger between extracellular stimuli and the metabolism of glomus cells. Results obtained provide the evidence of heterogeneity of carotid chemoreception mechanism.
