[Substantiation of the program of realization of bases of the state policy of a healthy nutrition of population of the Samara Region for the period till 2020 year].

Substantiate the need for long-term program of sanitation the diet of the population of the Samara Region. A systemic analysis of actual nutrition of different population groups in the region showed an excessive consumption of fats and added sugar--the main risk factors of obesity, cardiovascular diseases and diabetes mellitus. The risks of inadequate consumption of vitamins B, calcium, iron, caused by the irrational combination of the foodstuff use, are revealed.

[Comparative analysis of the migration increase dynamics of the elderly population living in the Samara region].

On the large amount of factual material we studied the dynamics of net migration of elderly in urban and rural areas of Samara region for the period from 2002 to 2009. We made a comparative analysis of changes in the structure and settlement characteristics of different groups of migrants (the elderly, children and able-bodied). We came to the conclusion, that the net migration of elderly in Samara region has considerably grown, mainly due to the influx of female population. The vector of net migration of people over working age moved into the countryside and this growth is ensured by older women to a large extent. The research results of one of the main demographic processes, migration, should be considered in the formation of local and regional policies for the elderly.

[Optimization of isolation of the concentrate of stem cells from the umbilical blood].

AIM: To study correlations between body mass and height of the newborn, Apgar scale estimates, gestation time, volume of the obtained umbilical blood (UB), number of nucleated cells (NC); to compare manual and automatic modes of UB processing. MATERIAL AND METHODS: 330 procurements of UB were made, 230 (69.7%) samples were frozen. Comparison of 2 techniques of UB processing was made in 73 cases of double centrifugation with hydroxyethylstarch (HES) and 47 cases of using separator Sepax (Biosafe, Switzerland). Blood cell count before and after UB processing and number of CD34+ cells were estimated. RESULTS: A correlation analysis was made of dependence of the volume of 102 samples of UB on the weight (r = 0.268, p < 0.01) and height of the fetus (r = 0.203, p < 0.05), estimation by Apgar scale (r = -0.092, p < 0.1) and gestation term (r = -0.003, p > 0.1); analysis of the number of NC dependence on the volume of UB (r = 0.102 p < 0.1), mass (r = 0.073 p > 0.1) and fetus height (r = 0.121 p > 0.1), gestation time (r = 0.159 p > 0.1), Apgar scale assessment (r = -0.174 p > 0.1). In manual UB management NC yield made up 71.9 +/- 6.7%, in automatic--81 +/- 8.0% (p < 0.05). Percent of erythrocytes removal was 73 +/- 5.7% and 80.5 +/- 6.1% (p < 0.05), respectively. CONCLUSION: A weak correlation was found between UB volume, mass and height of the fetus. The number of NC in UB depends on none of the parameters. Automatic processing of UB provides a greater release of NC and better elimination of erythrocytes in minimal risk of contamination.
