[A method of preparing a reagent for assessing the activity of the second component and factor B of the complement system].

The method is intended for preparing a reagent for the detection of the second component and factor B of the complement system. It makes use of an unsophisticated device for even time-controlled heating of the serum by letting it pass through a coil pipe submerged in the bath. The resultant reagent is used to measure the activity of the second component and B factor of the complement system and may be used for assessing humoral immunity in patients.

[Rapid method of measuring the alternative activity of the complement system].

The method is based on the ability of inulin to activate the alternative route of the complement system. The alternative activity is assessed from the consumption of the third complement component as a result of interaction with inulin. C3 is measured in experimental and control samples by kinetic titration, which permits assessing the activation of the alternative route in patients sera in less than 2 hours.

[Complex radionuclide diagnosis of phlebothromboses in patients with cancer of the corpus uteri].

The data on a complex radionuclide examination of veins of lower extremities carried out in the course of diagnosis of phlebothrombosis in cases of cancer of cervix uteri are presented. Radionuclide measurements with 125I-fibrinogen were carried out for diagnosis of venous thrombosis in lower extremities in 38 surgical patients and the signs of thrombosis were identified in 8 cases (21.1%).

[The HLA system of the Uzbek population in the Ferghana Valley. HLA antigens, genes and haplotypes of the Uzbek population in relation to its ethnogenesis].

Pecularities of distribution of 40 HLA antigens within the Uzbek population of the Ferghana Valley have been studied. The frequencies of these antigens are subdivided into three main groups having frequencies characteristic of the following populations: Caucasoid population (A9, B40, Bw22 etc.); Mongoloid population (B8, B7, B12); Middle Asian population (Aw31, B13, B16, Bw35), probably.
