title: [Serum lipid and lipoprotein fractions in 2 age groups of male rabbits].
abstract: The authors examined in 125 young sexually mature and in 50 young sexually immature male rabbits of a New Zealand improved Bulgarian breed the following serum lipid indices: total lipids, total and free cholesterol triglycerides, phospholipids, cholesterol and triglyceride content of VLDL (very low density lipoproteins), LDL (high density lipoproteins), HDL (high density lipoproteins) and the percentage concentration of serum lipopropteins, examined electrophoretically. The concentrations of the examined lipid and lipoprotein fractions in the sera of both age groups of rabbits showed asymetrical distribution. The hystograms of the total lipids and total cholesterol in younger animals was excluded. The logarithnictrandsformation of asymetricaly distributed concentrations of the examined fractions normalized their distribution in a part of them. The authors determined the ranges of the norm with the help of the percentile analysis in the remaining indices with asymetric distribution. Serum lipid and lipoprotein profile revealed substantial differnces in both age groups of animals. Serum lipids and lipoproteins in young sexually mature male rabbits differed from those of a man not only by their absolute concentrations, but also by their structural characteristics.
