[The alternative view on diagnostic of hyperlipoproteinemia, cholesterol lipoproteins of low density and effect of statins: a lecture].

The effect of statins occur in several stages: 1) inhibition in hepatocytes of synthesis of functionally specific pool of spirit cholesterol, polar mono-layer of lipoproteins of very low density; 2) activation of hydrolysis of triglycerides in lipoproteins of very low density, formation of apoE/B-100-ligand and absorption of lipoproteins of very low density by insulin-depended cells; 3) decreasing of content of and spirit cholesterol-lipoproteins of very low density in blood plasma; 4) activation of hydrolysis of triglycerides in lipoproteins of low density, formation of apoB-100-ligand and absorption of lipoproteins of low density by insulin-independent cells; 5) decreasing of level of and increasing of content of lipoproteins of high density. During first weeks of effect of statins occurs decreasing of concentration of triglycerides and unesterified spirit cholesterol-lipoproteins of very low density in blood plasma. Then, slower and more durational decreasing of level of spirit cholesterol-lipoproteins of low density occurs. The value of spirit cholesterol-lipoproteins of low density is primarily determined by content of palmitic saturated fatty acid in food, its endogenous synthesis from glucose and concentration of palmitic triglycerides and lipoproteins of very low density of the same name in blood plasma. The effect of preparations is biologically valid and corresponds to alternative hypolipidemic preparations. All these preparations have an effect following a common algorithm: they activate, using different mechanisms, receptor absorption of lipoproteins of very low density or lipoproteins of low density by cells. The level of spirit cholesterol-lipoproteins of low density in full measure depends on content of triglycerides in blood. The concentration of spirit cholesterol in blood plasma has a reliable diagnostic significance only under physiological content of triglycerides. The main criterion of diagnostic and control of hypolipidemic therapy biologically is content of triglycerides. The comprehension of differences in effect of hypolipidemic preparations within framework of common algorithm permits rationally combine them under treatment of both primary inheritable phenotypes of glucolipoproteins and secondary symptomatic types of glucolipoproteins under obligatory observation of strict dietary treatment.

[Laboratory diagnosis of herpesvirus infections in patients with acute leukemias].

The paper presents the results of monitoring the markers of herpes simplex viruses types 1 and 2, cytomegalovirus, Epstein-Barr virus, and human herpesvirus type 6 in the blood and bone marrow of patients with acute leukemias during induction multidrug therapy. Whether it is expedient to diagnose herpesvirus markers in patients with acute leukemias in the period of remission induction is discussed.
