title: Effect of polyenoic phospholipid therapy on lecithin cholesterol acyltransferase activity in the human serum.
abstract: The effect of polyenoic phospholipids on the concentration of serum lipids and the activity of lecithin cholesterol acyltransferase (LCAT, E.C. 2.3.1.43) was investigated in 18 patients with chronic glomerulonephritis accompanied by hyperlipaemia and reduced rate of cholesterol esterification in the plasma. The effects of therapy were evaluated immediately after a 2-month period of treatment and again after a 3-month drug free interval following termination of the therapy. An immediate effect of the treatment was reflected in a significant increase in the fractional esterification rate (FER % .h-1) and a marked reduction of the concentration of triglycerides (TG). Discontinuation of the drug resulted in the return of TG and FER values to the initial levels and in a rise of total (TCH) and unesterified cholesterol (UCH), HDL-cholesterol (HDL-TCH) and the molar esterification rate (MER mumol.1-1.h-1). The activity of LCAT estimated by radioassay in common and endogenous substrates varied in parallel.
