Morphological and physiological parameters of erythrocytes in oxidative stress at different stages of ontogenesis The results indicate the age-related deviations from physiological level of the prevailing number of the investigated morphological and physiological parameters of peripheral erythrocytes functional status, indicating the lack of these indicators stability in the late ontogenesis, significant defects of the gas transmission function of red blood cells, especially presented when inhale rats with hydrogen sulfide gas.  

The effect of Mexidol on clinical and immunological status of patients with chronic obstructive pulmonary disease The assessment of efficiency of meksidol therapy on clinical and immunological status has been made for patients with chronic obstructive pulmonary disease (COPD), the acceptability of physical loads, quality of life and probability of survival of patients with COPD being cousidered against the background of mexidol treatment. It has been established that the use of this preparation in a complex therapy for COPD patients is accompanied by positive dynamics of respiratory symptoms and improves the quality of life of patients. Patients with COPD have a depression of absorbency of neutrophil phagocytics capacity and increasing its metabolic activity with the formation of reactive oxygen species, the probability of a 4 year survival in patients with COPD.  

Research on the influence of endogenous bioregulators, isolated from blood serum and bones of mammals, on the regeneration of amphibian limbs The purpose of this study was to investigate the effect of bioregulators (BR) on anurans limb regeneration and to maintain the viability of the tissues of the developing salamanders regenerate in vitro. During this work it was found that the ability of Xenopus laevis to regenerate hindlimb in metamorphosis stage depends on the level of amputation, while stimulating regeneration by BR isolated from blood serum, decreases when the regenerative capacity increases. BR from serum had a pronounced effect on the regeneration of Xenopus laevis hindlimb in vivo when amputation was in the proximal region. BR from bone and BR from serum had a protective effect on the condition of the tissue regenerated limb of the newt Pleurodeles waltl provided by cultivation in vitro.  

Investigation of thermal resistance and antagonistic properties of the yeast Saccharomyces cerevisiae Using antagonistic properties of some bacteria to inhibit other (pathogenic) has been studied for many years, while little attention was paid to study such properties in yeast. The yeast metabolites and yeast cells action on gram-negative and gram-positive microorganisms was different. Live yeast cells were the most antagonistically active against gram-positive microorganisms and their metabolites - in relation to gram-negative.  

Regularities of formation and erosion processes during spring snowmelt on the territory of agrolandscape and their impact on the quality of river water Analysis of the results four years of research of the snowmelt runoff formation and soil loss on the catchment area of the small river Lubozhikha showed that surface runoff and soil washout has an influence not only on the intensity of erosion processes, but also on the chemical composition of river waters.
