[Effect of excess protein diets on lipid metabolic indices].
During 6 months the rats of different groups received isocaloric semi-synthetic diets that contained 18, 23, 28, 33, 38 and 43% protein (as regards caloricity). The most optimal magnitudes of the test characteristics of lipid metabolism--insignificant level of total lipids, total cholesterol and glycerides, the proportion of phosphatidylcholines and phosphatidylethanolamines in the content of phospholipids, the esterification ratio, the proportion of pre- beta- and beta-lipoproteins--were recorded in the groups given 18 and 23% protein in terms of caloricity. Further increase in the diet protein content produces a number of unfavourable shifts as regards lipid metabolism in white rats.
