[Lipids and the lipoprotein spectrum of blood in men engaged in intensive mental activity].

A group of 242 males, aged 35 to 45 years, employed as engineers in several research institutions, was examined. The examination was conducted in accordance with WHO recommendations. Among the biochemical indices the blood level of lipids (cholesterol, triglycerides) and the lipoprotein spectrum of the blood serum were determined by means of polyacrylamide gel electrophoresis. Distinct hypercholesterinemia was noted in 8.7% of the examined males, hypertriglyceridemia--in 23.8%. The revealed peculiarities of the lipid metabolism combined with the characteristics of the lipoprotein serum spectrum permitted to demonstrate the prevalence of Type IV hyperlipoproteinemia in 27% of those with diagnosed ischaemic heart disease, in 19.4% of those with the above pathology suspected, and in 18% of practically healthy individuals. Other types of hyperlipoproteinemia, type II in particular, were less common (4.7%, 6.1% and 2.6%, respectively).
