An attempt was made to identify specific monoamines contained in the dumb-bell shape cells of the frog taste bud by means of histochemical analysis. It was shown by fluorescent microscopy that preliminary administration of exogenous serotonin into the blood channel of frog tongue resulted in a sharp increase of specific fluorescence of the dumb-bell shape(More)
Cholinergic and adrenergic components of vegetative innervation in acupuncture zones of the human skin (in acupuncture "points") were studied by the histochemical method for acetylcholine esterase and by the method of luminescent microscopy. Skin samples were obtained by means of biopsy. In 23 corporal acupuncture zones in the skin, cholinergic nerve(More)
Special dumbbell-shaped cells of unknown nature, rich in catecholamines and giving a specific yellowish-green luminescence, were found inside the taste buds. The taste buds responded differently to preliminary (24 h before taking the material) injection of reserpine (0.25 mg). In some taste buds the dumbbell cells lost their property of specific(More)
The structure of catecholamine-containing dumb-bell shaped cells of the taste buds was studied by luminescent microscopy in the epithelial layer of the frog's tongue (Rana temporaria). On the unilateral section of the lingual nerve, a maintained adrenergic innervation of vessels and of the epithelium was observed, a decreased number of dumb-bell shaped(More)
