[Age-related changes in the physical development of Kabardin-Balkarian school-children living at various heights above sea level].
Four and eighty-one schoolchildren aged 7-17 years, living at a height of 2100 m above sea level, and 1677 schoolchildren of the same age, living at a height of 100-400 m above sea level, from the Kabardin-Balkarian Republic were examined by the list of morphological indices of physical development (PD), such as height (cm), body weight (kg), and chest circumference (cm). The results were rated by using the 5-score scale, by calculating the integral indicator of PD (low, moderate, and high). The schoolchildren living at high heights were ascertained to have high values. ⋯ The geographical differences in three parameters of PH between Kabardin-Balkarian schoolchildren were heterodirectional: the altitude children outrun the plain one in height during a short period of time (the boys outrun at the age of 10 to 13 years; the girls do at the age of 11 to 14 years). In terms of body weight, the children from the study groups either outrun, or lag each other, in the boys and girls, these variations being opposite in time. From the age of 10 years, the altitude children of both sexes surpass the plain ones in chest circumference.

[The situation and preventive measures against the spread of avian influenza on the territory of the country].
The Russian Federation, as the whole world community, is anxious about the established situation associated with the prevalence of avian influenza and a threat of its pandemic. Today avian influenza is a complex, i.e. medical, veterinary, social, and economic, problem. Since December 2003, the world has notified an avian influenza panepizootic that has covered 54 countries to date. ⋯ Three inactivated emulsified veterinary vaccines against avian influenza have been currently designed. The calculated size of poultry to be vaccinated is 74.6 million. Double vaccination requires that 150 million doses of the agent be manufactured.

[Hygienic assessment of working conditions and functional resistance in electric power station workers].
The exceeding maximum permissible levels, the parameters of electromagnetic fields and radiations, an electrostatic field, noise, and vibration are the leading adverse factors of the industrial environment for basic professional groups of Stavropol district electric power station workers. According to the degree of harmfulness and hazard, the working conditions are referred to as Class 3 ("hazardous") in 93.7% of the personnel. The significant tension of adaptive mechanisms is typical of most patients (76.3%). Based on the multivariate analysis of the results of a psychophysiological follow-up, the authors have developed a procedure for the integral evaluation of the functional state of the workers' organism, which may be used in the sociohygienic monitoring system in the electric power system of Russia.
