title: [Reflexotherapeutic effects on biologically active points of the concha auriculae].
abstract: By means of histochemical method, for revealing cholinergic nervous structures, and electron microscopy, innervation of biologically active points (BAP) and that of neutral areas of the rabbit ear skin has been studied, normal and after acu-, electro- and electroacupuncture. The BAP have more intensive vascularization and innervation, their specific feature is presence of well pronounced nervous fasciculi. The latter are formed by 6-10 fibers 1-6 mcm in diameter. The diameter of the fasciculi is within the limits 25-30 mcm up to 40-45 mcm. Under the electron microscopic investigation myelin and amyelin fibers are revealed in the nervous fasciculi. In the area of the epidermal basal layer and in the epidermis itself, single nerve terminals are found; they are considered as the point pain receptors. After acu-, electro- and electroacupuncture, intensity of the nervous fibers staining increases, thus demonstrating an increment of acetylcholine esterase activity. After insertion of acupuncture needles and after electrical irritation, the changes in the nervous and cellular elements in the BAP areas are studied electron microscopically. After the effects mentioned, mast cells situating in the BAP area become, as a rule, degranulated. After repeated electroacupuncture irritation of the BAP, an inflammatory focus appears with peculiarities specific for the given process. The reflexotherapeutic effect is supposed to be transferred via the nervous system. The mechanical irritation of the nerve fasciculi and the accompanying traumatization of the surrounding cellular elements initiate the mechanism of reflexotherapy.
