[Blood fibronectin and liver phagocytic function in peritonitis patients].

The concentration of blood fibronectin and the state of the phagocytic function in the liver was studied in 19 patients with an emergency pathology of the abdominal cavity complicated by the infective-toxin shock and polyorganic insufficiency. Patients with severe abdominal pathology had a considerably decreased level of circulating fibronectin, disturbed phagocytic function of the liver and development of the hypercatabolic state. Hypofibronectinemia was accompanied by polyorganic disorders, systemic bacteriotoxemia and disseminated intravascular coagulation.

[Plasma fibronectin level in patients with chronic diseases of the liver].

The diagnostic value of determination of plasma fibronectin in chronic hepatic diseases was examined on the basis of the data available in the literature and the authors' own results of studies. The procedure for measuring fibronectin in healthy subjects and patients with hepatic cirrhoses and chronic persistent hepatitis is briefly outlined. Possible mechanisms of fibronectin level alterations are discussed in these pathological processes.

[Functional activity of thrombocytes and granulocytes of donor blood after selective removal of fibronectin].

Storage of anticoagulated whole blood leads to the activation of platelets and granulocytes, formation of aggregates, lysis of cells, various thrombogenic substances, including proteolytic enzymes. Transfusion of the blood may cause capillary occlusion, intravascular coagulation, renal and hepatic dysfunction. Gel-silicagel affinity+ chromatography of the anticoagulated whole blood was shown to result in selective sorption of plasma fibrin.

[Methods of isolation and quantitative analysis of fibronectin in biological fluids].

The theoretical and methodological aspects of fibronectin isolation and quantitative determination in biological fluids are analysed on the basis of the communications available in the literature and the authors' own data. The procedure of applying the analyzed methods, potential complexity and errors in interpreting the data obtained by various methods are briefly outlined. Possible fields of their application, such as basic and clinical investigations, biotechnological production, etc.
