[Selected indicators of lipid metabolism in screening tests of managerial staffs]

The studies covered 60 men (average age 43.5 +/- 6.5 years), carrying on managerial functions (average length of employment 8.3 +/- 2.5 years). All subjects underwent standard determinations of total cholesterol (Liebermann--Burchard's method) and triglycerides (using Boehringer's enzymatic set) and lypoproteins electrophoretic distribution on polyacrylamid gel (Ames' firm). In 31 subjects lypoproteins distribution was performed, through precipitation, into fractions HDL, LDL and HLDL, in which the contents of cholesterol and triglycerides have been determined. In 40% of subjects, hyperlypoproteidemia, type IV (HL-IV) has been found, which would indicate the advisability to cover the managerial personnel by such studies. The HL-IV has been found to be accompanied by an extreme increase of VLDL fraction triglycerides and a significant increase of cholesterol of this fraction. Moreover, the HDL cholesterol concentration has been found to be decreased, as compared to normolypo-proteidemia. The results of electrophoretic distribution indicated a good correlation with the results of total triglycerides in blood serum.
