[Prophylaxis of hepatic insufficiency after major hepatic resections].

Unlabelled: The article deals with a problem of prophylaxis of hepatic insufficiency in oncological patients after liver resections.

Materials And Methods: We analyzed data of effectiveness and safety of the use of Remaxol in oncological patients with hepatic metastasis of colorectal cancer--dynamics of indicators of cytolysis and cholestasis, hepatic protein synthesis, exchange of pigments, pro- and antioxidant system and the level of endogen intoxication in postoperative period.

Results: Use of Remaxol allows decreasing the duration of postoperative rehabilitation and intensive care unit staying.

[Polyelectrolyte complexes of lactoferrin and pH-sensitive microparticles on their basis].

Suspensions of insoluble polyelectrolyte complexes of dextran sulfate? (DS) of different molecular masses with lactoferrin (LF) have been fabricated and characterized. The encapsulation efficiency of LF and DS in a complex at pH 3.0 and 4.

[Experimental study of remaxol as a drug for supportive therapy in traditional and high-dose treatment of tumors].

We have experimentally investigated the detoxifying and modifying effects of remaxol in the framework of traditional and high-dose chemotherapy in mice with transplanted tumors. The influence of remaxol in comparison with heptral was studied on the toxic and therapeutic action of cytostatic drugs gemzar, lastet (etoposide), and methotrexate during their traditional and high-dose administration in mice with transplanted P388 lympholeukosis. Remaxol demonstrated a detoxifying action with respect to these cytostatic agents, which decreased in the following series: gemzar lastet methotrexate (according to the results of lethality evaluation).

[The test system to identify mucin MUC1 in human blood serum using the technique of immune-enzyme analysis based on monoclonal antibody ICO25].

On the basis of genuine mouse monoclonal antibody ICO25 the test system IEA ICO25 was developed and standardized to quantitative detect tumor-associated antigen, mucin1 in human blood serum in format of inhibitory immune-enzyme analysis. The analytic characteristics of test-system correspond to the standards applied to immune-enzyme diagnostic kits. The results of identification of MUC1 in blood serum of healthy donors and female patients with breast pathology using IEA ICO25 fully correlate with the data concerning the detection of antigen CA15-3 using certified commercial kits.

[Effect of polysaccharides on biological activity of human lactoferrin].

The influence of neutral and ionic polysaccharides on the antioxidant (AOA) and detoxifying activities of lactoferrin (LF) and the duration of its circulation in the body was studied. In addition to natural polymers, we studied artificial chitosan derivatives with different functional groups. On the basis ofAOA test, five polysaccharides were selected.
