Data of hygienic studies of air and soil during last 20 years have confirmed their correlating relationship with the general morbidity and a group of musculoskeletal diseases in children living in cities with the technogenic pollution of the environment. Their bones were established to grow unevenly and disproportionally, in 76% of children there have been violations in the development and growth of bones. The results of X-ray examination of hand bones in children and adolescents in the Irkutsk and Shelekhov cities are presented. Significant differences in morbidity patterns among children and adolescents including an increased incidence of musculoskeletal diseases by 5.6 in children and by 12 in adolescents have been revealed.

Stroke is the second leading cause of death in the world. Unfortunately, only a few drugs have been proved in clinical trials. Drug development of the last decade has been focused substantially on a promising and heterogeneous group of neuroprotective drugs. Hundreds of compounds were suggested as new putative neuroprotectors, which effectiveness was confirmed in preclinical trials only. At the present time discrepancy between results of preclinical studies and clinical trials requires careful analysis. One of the least evaluated and probably the most noticeable reasons is general anesthesia--an obligatory component of an overwhelming majority of existing animal stroke models. The aim of the review is to describe known mechanisms of common general anesthetics influence on ionotropic and metabotropic plasma membrane receptors, and key signal pathways involved in neuronal hypoxic-ischemic injury and survival.
