title: [Lipoprotein metabolism analysis in arteriosclerotic diseases].
abstract: Lipoprotein metabolism was studied by analyses of apolipoproteins, cholesterol content in lipoproteins and electrophoresis. The findings obtained suggested that the apolipoprotein levels such as A1 and B are related with particle number of lipoproteins such as HDL and LDL, while cholesterol content in lipoproteins is affected by qualitative change in particles as well. In patients with diabetes mellitus (NIDDM), LDL cholesterol correlated with HbA1c, and cholesterol and apolipoprotein B in the beta-area on electrophoresis showed accelerated mobilities, which were mimicked by in vitro glycation of LDL. In coronary heart diseases, elevation of apolipoprotein B and a low level of HDL cholesterol were general findings. The B/A1 ratio could be a sensitive indicator for these diseases. Hyper HDL cholesterolemias, excluding the patients with prostatic cancer who had undergone estrogen-treatment, showed elevated levels of apolipoprotein E in alpha 2-area on electrophoresis. Heterogeneity in Hyper HDL cholesterolemia was implicated. Qualitative analysis of lipoproteins by our method is believed to be useful.
