Anions with strong electro-negative charges, like sulphuric esters of polysaccharides (heparin, dextran sulphate M.W. 15 00), the sodium salt of polyanethol sulfonic acid (liquoid, Roche), anionic detergents (sodium dodecylsulphate, sodium oleate, sodium deoxycholate), and the sodium salt of phosphotungstic acid were added to human serum or citrated plasma. For each compound several final concentrations were adopted, the highest being 4%. By using microimmunoelectrophoresis and numerous specific antisera against human plasma proteins, it was demonstrated that at pH 8.60 anions increase electrophoretic mobility of the following antigens: lipoproteins alpha and beta; fibrinogen; beta 2-glycoprotein I; beta 2-glycoprotein II ; antithrombin III. All reagents utilized do not react with all these proteins; for instance, only detergents accelerate the migration rate of a lipoproteins. Besides, depending on the protein, this or that reagent may be the most active. Thus, in the polysulphate group, heparin has the highest affinity for antithrombin III, liquoid for fibrinogen and dextran sulphate for beta 2-glycoprotein I.

Sera were sampled from 83 people (pre- and post-menopausal women and men). Climacteric symptoms of 23 women were treated with conjugated estrogen. Sera were sampled serially until the 21st day of estrogen administration. Serum concentrations of 40 protein components were measured by micro single radial immunodiffusion. The serum proteins were classified into 5 types according to changes after menopause and estrogen therapy, respectively. Type 1 (decreased after menopause and increased by estrogen; alpha 1-antitrypsin, alpha 2-HS - glycoprotein, beta 2-glycoprotein III, Gc-globulin, alpha 1-lipoprotein and alpha 2-AP-glycoprotein), type 2 (unchanged and increased; ceruloplasmin), type 3 (increased and decreased; alpha 1-acid glycoprotein, haptoglobin, serum amyloid P-component, Zn-alpha 2-glycoprotein, beta-lipoprotein and C1-components), type 4 (unchanged and decreased; hemopexin, antithrombin III, beta 2-glycoprotein I, prealbumin and retinol-binding-protein), type 5 (unchanged by estrogen; immunoglobulin M (IgM), IgG and others). Estrogen replacement therapy restored pre-menopausal levels of serum proteins, types 1 and 3. However, estrogen therapy was associated with significantly abnormal levels of proteins, types 2 and 4 in post-menopausal women. Serum levels of type 1 proteins and some type 5 proteins (IgM, alpha 1B-glycoprotein, C9-component and alpha 2-macroglobulin) were higher in pre-menopausal women than in men, whereas type 3 proteins were the opposite.

Thrombocytopenia prevalance and its association with antiphospholipid syndrome, disorders of the hemostasis system, the course and activity of the disease have been studied in SLE patients. 10.5% of 457 SLE patients in central and western part of Ukraine had thrombocytopenia which non-significantly depended on sex, age and disease duration but was tightly associated with cardiovascular disorders. Thrombocytopenia appears as an independent risk factor for vascular disorders which does not depend on lipid metabolic disorders and system inflammatory reaction but is firmly associated with the presence of antiphospholipid syndrome, beta-2-glycoprotein I levels, thrombocyte hyperactivity, antithrombin III and tissue plasminogen activator deficiency.
