[Statistical research on the lipides electrophoresis and on double pre-beta lipoprotein (author's transl)].

On 442 healthy subjects statistical research on cholesterol, triglycerides and lipoprotein electrophoresis on agarose was carried out. The results of statistical elaborations concerning average and standard deviation of the three lipoproteic bands (beta, pre-beta and alpha) are explained. 22 cases with double pre-beta lipoprotein (both normal and hyperlipoproteinaemic subjects) are described. The importance of this anomaly and its correlation with coronary atherosclerosis are pointed out.
