Abstract
The importance of electrolytes on the cardiac physiology is well known. Recently is assumed that potassium has a fundamental role in the chemical process of muscle contraction (Szent-Gyoergyi) and pottassium and calcium are receiving special attention due to the role played in the effect of cardiac glucosides. The intimate relationship between the calcium and potassium and cardiac muscle can never be too emphasized.As vita-campher (trans-π-oxocampher) is a drug frequently used for acute cardiac insufficiency, in Japan, the study of its influence on the metabolism seems to be important clinically.The author administered calcium, potassium and vitacampher to dogs and studied their effects on the consumption of oxygen, utilization of lactic acid, pyruvic acid and glucose in the cardiac muscle by the method of coronary sinus catheterization. At the same time, using Rotameter the influence of these manoeuvre on the coronary flow was studied.
