The concentration of homocysteine in blood serum among indigene and outsider population of priamurye

: The study evaluated the concentration of homocysteine in the most numerous groups of indigene population of Priamurye (Even, Ultch, Nanai) as compared with adjacent to them outsider population. The technique of random sampling was applied to select 82 Even, 89 Ultch, 95 Nanai and for comparing the representatives of outsider male and female population in statistically comparable numbers. The concentration of homocysteine was determined with luminescence immunoassay using the analyzer immulite 1000 (Diagnostic Products Corporation, USA) and applying Siemens kits (USA). The mean population values of homocysteine were reliably lower among indigene males and females as compared with representatives of outsider population. The lowest values of homocysteine were established among Even males and females, dwelling on the shore of Sea of Okhotsk. Whereas no reliable differences in concentrations ofhomocysteine in blood serum were established among Ultch dwelling in downstream of Amur river and Nanai dwelling in middle course of Amur river 240 km from Khabarovsk.
