[Dynamics of the lipoprotein distribution in early hypercholesterolemia characterizes the activation of cholesterol transport].
Using gradient gel electrophoresis, the levels of major classes of rabbit blood sera lipoproteins were studied over a period of 28 days. Hypercholesterolemia persisted up to the 4th day with a subsequent decrease. This was paralleled with an increase in the levels of triglyceride-rich and apoB-containing particles. The decrease of the electrophoretic mobility of low density lipoproteins correlated with an increased content of the intermediate fraction. On the 28th day after the beginning of experiment the concentration of total high density lipoproteins showed an increase. The subfractional redistribution of HDL3 and HDL2 subclasses pointed to the stimulation of the accepting process and the overall reverse cholesterol transport system. A comparison of experimental results with literary data allowed to conclude that the relative decrease of the serum cholesterol level typical of hypercholesterolemia of one month duration is due to the activation of specific and nonspecific preventive mechanisms.
