EXPERIMENTAL STUDIES ON THE AUTONOMIC NERVOUS CENTERS AND THIAMINE METABOLISM IN RABBIT SKIN : (II) CHANGE IN PYRUVIC ACID CONTENT IN THE BLOOD AND SKIN DUE TO THE ELECTRICAL STIMULATION TO THE HYPOTHALAMUS

Abstract

Investigations were made on the change in pyruvic acid content in the blood and skin of rabbit due to an electrical stimulation to hypothalamus of the animal using Kurotsu' apparatus. A marked increase was recognized in the pyruvic acid content both in the blood and skin by the stimulation to b-sympathetic zone, while no change was observed by the treatment to c-parasympathetic zone.
