Key biological structures of the human being's informational image.

This article deals with the corporeal and informational images of human beings. These images can be represented by key biological structures, such as biocells, nerve fibers, and acupuncture points. These structures are shown to transmit and process informational signals by means of electromagnetic (field) waves. An experimental setup is designed to study biological structures in the millimeter-wave range.

[Enzyme immunoassay of human chorionic beta-gonadotropin in biological fluids using photographic detection]. / Immunofermentnyi metod opredeleniia beta-khorionicheskogo gonadotropina cheloveka v biologicheskikh zhidkostiakh s ispol'zovaniem fotograficheskoi detektsii.

Potentialities of a new detection method making use of photographic information transformers were demonstrated as exemplified by enzyme immunoassay of human chorionic beta-gonadotropin. Commercial enzyme immunoassay kits for measurements of human chorionic beta-gonadotropin manufactured by Diaplus joint venture were used in the study. The results of traditional spectrophotometric detection and photographic detection were in good correlation, the correlation coefficient r being equal to 0.882. The sensitivity of the method permits reliable testing of clinically significant gonadotropin concentrations in biologic fluids.

[The use of photographic materials as a dry reagent for determining the peroxidase activity of biological preparations]. / Primenenie fotomaterialov v kachestve "sukhogo" reagenta dlia opredeleniia peroksidaznoi aktivnosti biopreparatov.

A new method is reviewed for measuring the peroxidase activity of biopreparations using light quantum-sensitized photographic material as a detector. The method involves the combination of the reactions of peroxidase oxidation of hydroquinone, a constituent part of the developing solutions, by hydrogen peroxide and photochemical interaction of the remaining hydroquinone with silver halogenides of the photoemulsion layer. Visually, up to 2 ng/ml of horse radish peroxidase is detectable. On photometry of the spots obtained, the limit of peroxidase demonstration amounts to 0.6 ng/ml. The data obtained during measurements of the peroxidase activity of the saliva, blood serum, plant extracts and immunoenzymic conjugates are provided.

[Possibility of using immunologic indicators in evaluating the effect of pesticides on the body]. / Vozmozhnosti ispol'zovaniia immunologicheskikh pokazatelei v otsenke vozdeistviia na organizm pestitsidov.

The modern problem of pesticide-related pathogenic body effect has been studied from different points of view. However, some medical aspects of pesticide-induced diseases, primarily their effect on the immune status, remain insufficiently explored. The study is designed to analyze pesticide effect on basic indicators of humoral and cellular immune factors and also to develop a new principle for assessing their exposure according to the degree of immune changes in those exposed to pesticides. Proceeding from the study results it is possible to conclude that under long-term exposure to pesticide microdoses the human body undergoes complex changes: there develops autoimmunization accompanied by the manifestation of antitissue autoantibodies, reduction of serum complement activity, relative content of T-lymphocytes and elevation of the level of B-lymphocytes. Toxicant-related body sensitization and decline in immuno-resistance can serve as the main cause for the deterioration of health status of the residents of the rural areas characterized by higher chemical exposure.
