A procedure is proposed to identify non-volatile organic acids in small human plasma volumes by gas liquid chromatography (GLC), which shows a high degree of acid separation with the rather simplified preparation of samples. The principle of the procedure is deproteination, simultaneous perchloric acid neutralization, plasma lipid hydrolysis, transformation(More)
The aim of our research was to investigate the contents of lipids and fat-soluble vitamins in blood plasma of aboriginal adolescents of Russian European North (komi, n=104). It was established that there are specific Lipemic index at aboriginal adolescents: low level of the general cholesterol, triglycerides, transport lipoproteins both their albuminous(More)
Study of the effects of acute normobaric hypoxia was performed on a group of young healthy males (age 19-23, n = 10). Conditions of acute normobaric hypoxia were modeled by using oxygen-nitrogen mixture containing 8% of oxygen as a breath gas. That level of oxygen corresponds with its partial pressure at 7000 meters above sea level. A number of different(More)
We demonstrated significant changes in levels of several plasma free amino acids--proline, hydroxyproline, glycine, and phenylalanine--in healthy volunteers in response to severe acute normobaric hypoxia (breathing nitrogen-oxygen mixture with 9% of O2). We assume that demonstrated an increase of free proline, hydroxyproline, and glycine in plasma in the(More)
The relationship of ratio of apolipoprotein (apo) B/apoA-1 with other indicators of lipid metabolism in healthy people with normal lipemia was analyzed. The dependence of ratio of apolipoprotein (apo) B/apoA-1 from content of apoE (X2=8.20; p=0.042) was established. Under low indicators of apoE risk of detection of unfavorable ratio apolipoprotein (apo)(More)
Evaluated were consequences of changes in oxygen demand, bronchial conduction, exercise performance, functioning of antioxidant enzymes and body provision with natural oxidants for the level of free-radical oxidation products in human organism. To this end, a group of essentially healthy young male northerners spending much time outdoors was surveyed over a(More)
The influence of acute normobaric hypoxia on total pool of human plasma fatty acids was studied in experiment (respiration of hypoxic gas mixture containing 8% of O2, during 25 min). Health status of participants-volunteers and the hypoxia intensity were monitored with a complex of electrophysiological methods: EEC, ECG, measurement of blood pressure, SpO2,(More)
