[Use of detergents for elimination of non-specific reactions of monoclonal antibodies]. / Primenenie detergentov dlia ustraneniia nespetsificheskogo reagirovaniia monoklonal'nykh antitel.

The purpose of the case study was elaboration of methods for removing the false-positive results in the detection of virus antigens that cause acute respiratory lesions both in the plane and dot-membrane variations of immune-enzyme assays of monoclonal antibodies. Modeled experiments showed that the non-specific staining of biological samples, in which the above viral antigen are looked for, is preconditioned by a direct reaction of the substrate with its own oxidizing enzymes and by the binding of monoclonal antibodies with biological macromolecules free of any viral adherence and sorbated in the solid phase. Approaches to solving such issues are described in the paper. They comprise the inhibition of the own oxidizing activity of wash-outs by the substrate and the application of detergents. Different detergents were comparatively analyzed and the optimal compounds were chosen for each variation of immune-enzyme test-systems. The described techniques ensure more reliable results in the viral antigen detection by immune-enzyme assay.

[Glucose utilization in influenza of varying severity in intact or stressed animals]. / Uvoenie gliukozy na fone grippoznoi infektsii raznoi tiazhesti u intaktnykh ili stressirovannykh zhivotnykh.

Animals preexposed to stress developed manifest hyperglycemia in the first 2 days of influenza infection, which was replaced by prolonged hypoglycemia. The status of carbohydrate metabolism normalized no sooner than 3 to 4 weeks after the disease onset, although the acute phase of infection was over by the end of week 2. The changes were evident in the pattern of "sugar curve" after glucose loading. Glucose utilization failed to normalize even 2 h after the loading in animals with stress, influenza infection, or stress-associated complications of this infection.
