[Perspectives of disodium salt 2.4-di(1-metoxyethyl)-deuteroporphyrin - IX ("Dimegin") application for photodynamic therapy in non-oncologic cases].

Effects of disodium salt 2,4-di(1-metoxyethyl)-deuteroporphyrine-IX (Dimegin) and the light from Soret band (»395-405 nm) at the viability of microbial cells and at their potential to form microbial biofilms have been compared with traditional antiseptics. Irradiation of microbial cells of S. aureus, E.

[Testing of the system of biochemical and immunological indices of the state of population health in the survey of residents of Moscow, exposed to ambient air pollution].

New biomarkers of effect of some controlled ambient air pollutants (formaldehyde, carbon monoxide and TSP) were found in two surveys of Moscow residents (apparently healthy and outpatients with allergic diseases) with a help of screening system of biochemical and immunological parameters. Possible mechanisms of the effects, including interference of atmospheric carbon monoxide and sulfur dioxide with corresponding endogenous second messengers, are discussed.

[Enhanced serum DNAase activity in hypersensitization to pollen allergens].

Factor analysis of cross-sensitization to 24 common allergens and correlation analysis of the relationship between the hypersensitivity to the allergens and some biochemical markers (the intensity of serum chemiluminescence, the content of SH-groups, and the activity of lysosomal enzymes) of the health status were carried out in a sample of Moscow residents with allergic diseases. A significant correlation was found between the serum levels of specific IgE antibodies to pollen allergens and the activity of serum acid DNAase (R = 0.498; p = 0.

[Skin resorptive effect of petroleum on some biochemical and immunological parameters in experimental animals].

Petroleum and its transformation products accumulated in soil along multiple trophic chains enter the human body, which increases the risk of environmentally induced diseases. A thirty-day experiment studied the cutaneous effect of different doses (4250, 850, and 425 mg/kg) of sunflower oil-emulsified petroleum. Its sensitizing and allergic effects were studied on albino guinea pigs.

[Development of an extended immunological system parameters for assessment influence of environmental factors on the population's health status].

The immune status of Moscow dwellers was studied. The findings indicate the criterion significance of immunological and allergological parameters in the estimation of a risk of allergic diseases under the influence of poor environmental factors influence. Hyperactivity in individuals with high immunoglobulin class E levels to environmental factors is suggested by the elevated concentrations of serum specific IgE to intrahouse factors that in combination with the increased levels of anti-inflammatory cytokines (interferon-gamma, tumor necrosis factor-alpha) and the suppressed production interleukin-4 are criteria for the early manifestations of allergy.
