Studies on Lipids of the Coronary Artery and Aorta

抄録

1. Contents of triglyceride in the grossly normal intima preparations of the coronary artery obtained from Japanese autopsies (41-60 yrs) were approximately 5 mg per gm of defatted and dried tissue weight, which were not significantly high compared with those in the other arterial specimens. The previous results showing a high content of triglyceride in the coronary artery were considered to be resulted from the contamination of the adipose tissue, because less than a few percentage contamination of the adipose tissue can result in a significant increase of triglyceride content of the artery. 2. The incorporations of (1-C¹⁴) acetate into digitonine precipitable sterol and bound lipids as well as FFA, PL and TG were significantly observed in the arterial wall.
