BIOCHEMICAL STUDIES ON THE AURICULO-VENTRICULAR JUNCTIONAL SYSTEM OF HEART

IV. Studies on the Anaerobic Oxidation of t Auriculoventricular Junctional System

Abstract

1. The auriculo-ventricular junctional system of heart is very resistant against cyanide.
2. The auriculo-ventricular functional system poisoned with M/2500 KCN can consume oxygen to a certain extent.
3. The auriculo-ventricular junctional tissue does not give utp its automatic contraction in Locke's solution practically free f rom oxygen.
The author wishes to express his heartiest thanks to Prof. Keizo Kodama and Prof. Makoto Ishihara for their kind advice throughout the course of this investigation.
