Abstract
Up to the present, the quantity of phosphatide in sera was measured chemically by many investigators. If I put together what they said, I came to the following conclusion-on the easily infectious condition the phosphatide in sera increased and after exercise it increased in sera and decreased in muscles. I could measure serologicaly the quantity of phosphatide in sera by ACPR. Then, in the patients' sera with myocardial lesion, especially in the allergic condition the myocardial phosphatide increased, namely ACPR showed higher value.
