[Prevention of a stress-induced drop in the threshold of cardiac fibrillation using transauricular electroacupuncture].

The effect of electroacupuncture on stress-induced drop in cardiac fibrillation threshold and catecholamine content in the adrenergic terminals of the myocardium was studied in Wistar rats. Transauricular electroacupuncture causing drowsiness in animals was found to prevent a drop in cardiac fibrillation and norepinephrine level in the adrenergic terminals usually observed after long immobilization stress. It is assumed that the preventive effect of acupuncture may be attributable to reflex activation of the inhibitory brain system which restricts stress reaction.

[Certain problems in the autonomic innervation of acupuncture zones of human skin].

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 conductors and terminals were found to be concentrated and structurally connected with multiple vessels of the skin and its derivatives: sweat glands, folliculi of the fluffy hairs and smooth muscles.
