[Immunoenzyme method of determining thymus polypeptide factor]

A rapid indirect enzyme immunoassay technique for the determination of thymalin, a polypeptide thymus factor, with sensitivity equal to 1.5 X 10(-8) mol/l has been developed. The accuracy of determinations, measured by the variation factor, has proved to be 5-10% in the interassay, 10-15% in the interassay, the reliability in the opening test being 5%. The assay takes 4.5-5 hours.

[The effect of polypeptides from the thymus, bone marrow and bursa of Fabricius on the immunogenesis and hemostasis in neonatally thymectomized and antenatally bursectomized chickens]

The effect of polypeptides from the thymus, bone marrow and bursa of Fabricius on immunogenesis and hemostasis was investigated in neonatally thymectomized and antenatally bursectomized chickens. It has been established that polypeptide factors from the bursa of Fabricius have the most pronounced effect on the immunity and hemostasis.

[The vascular wall as an efferent regulator of immunogenesis, hemostasis, the kallikrein-kinin system and regenerative processes]

Polypeptide factor isolated from vascular wall of the cattle ("vasonin") was shown to affect the immunogenesis and hemostasis, to stimulate kallikrein-kinin system and to accelerate processes of regeneration.

[Effect of polypeptides isolated from the heart on the course of experimental myocardial infarct]

Polypeptides excreted from the heart have been shown to exert a positive influence on myocardial infarction caused by izadrin injection in experimental rats.

[Simulation of thymus hypo- and hyperplasia by thymalin in guinea pigs]

Potentialities of the modulation of thymus function with thymalin and the hormonal-immunological status in simulated hypo- and hyperplasia of the thymus. The advisability of the use of the drug was shown.

[Effect of the vascular wall polypeptide factor vasonin on hemostatic function in an experimental peroxidation syndrome]

The process of blood coagulation was found to be activated in the peroxidation syndrome caused by the use of antioxidant-free diet. Vasonin prevents the development of hypercoagulation in rabbits at the peroxidation syndrome but fails to prevent the development of the latter.

[Fournier's gangrene]

The authors describe 6 cases of Fournier gangrene. Early necrectomy and intensive conservative therapy should be used as the main method of treatment. Perfect recovery after extended defects of the skin was observed only following successful skin-plastic operations. Two patients died.

[Effect of thymalin on thrombocyte aggregation and the antiaggregation activity of the vascular wall in intact and thymectomized rats]

Administration of immunomodulator thymalin to intact rats was shown to produce reduction of platelet aggregation ability and to exert no effect on antiaggregation activity of the aorta. Thymectomy resulted in an increase of platelet number and their aggregation ability and an increase of antiaggregation activity of the vessel wall in the rats. Thymalin administration to thymectomized rats normalizes platelet hemostasis parameters. The role of the thymus in the regulation of platelet hemostasis is discussed.

[Use of thymalin and heparin in acute peritonitis]

Results of the investigation of parameters of cell and humoral immunity and coagulogram in 63 patients with acute peritonitis have shown that thymalin when used solely or in combination with heparin facilitates quicker arrest of the pathological process, its clinical and laboratory symptoms. The combination of thymalin and heparin is indicated to elderly patients and in cases with higher risk of thromboformation.

[Effect of polypeptides from the prostate on the hemostasis system]

It has been shown in rat experiments that polypeptides from the prostate exert no essential influence on blood coagulation and fibrinolysis but increase antiaggregation activity of the vessel wall.
