  • Title: [Microfluorimetric study of adrenergic structures in nerve plexuses of the pelvic cavity of the normal and decentralized cat].
    Author: Lapsha VI, Bocharova VN.
    Journal: Neirofiziologiia; 1986; 18(4):496-502. PubMed ID: 3762794.
    Abstract:
    Microfluorimetric technique was used to study catecholamine concentration in small intensely fluorescent (SIF) cells and in adrenergic fibres of the pelvic plexus ganglia and intramural ganglia of the cat urinary bladder and rectum in control and following sympathetic and parasympathetic denervation. Two types of SIF-cells were studied: cells of the first type contained catecholamines and those of the second type--serotonin. Parasympathetic denervation resulted in an increase of SIF-cells which exhibited serotonin fluorescence, and in more intense fluorescence of adrenergic fibres in the pelvic plexus ganglia and intramural ganglia of the urinary bladder, not affecting the intensity of fluorescence of the adrenergic fibres in the intramural ganglia of the rectum. Sympathetic denervation did not alter the fluorescence intensity in SIF-cells and adrenergic fibres in the pelvic plexus ganglia and urinary bladder and led to almost complete disappearance of the adrenergic fibres in the intramural ganglia of the rectum.
