Ascending aortas, abdominal aortas and pulmonary arteries were collected from 36 cadavers of old men, and amounts of water content, total nitrogen, reduced substance, hexosamine, sulfuric radical, metachromasic substance, cholesterol, Na, Ca and P, all of which are fractions easily extractable with water contained in the walls of these arteries, were determined to seek relation between arteriosclerosis and change in these values, with the following results:
1) There was no remarkable difference between the ascending and abdominal aorta in the values of total nitrogen, hexosamine, and reduced substance, and these values were lower in the pulmonary artery than in the two aortas. No significant difference in sulfuric radical was observed between the three.
2) Water content was found decreased in sclerotic part as compared with non-sclerotic part.
3) Total nitrogen, hexosamine, reduced substance, sulfuric radical and metachromasic substance were all decreased in sclerotic part.
4) Cholesterol value was increased in sclerotic part.
5) In sclerotic part, Ca content was increased, but Na content was contrarily decreased.
6) In sclerotic part, total P and acid-soluble P were found increased, but change in inorganic p and lipid P was indistinct.
7) Significant correlation was observed between hexosamine and sulfuric radical in arterial wall which were determined by the acid hydrolysis method.
