The gas chromatographic method was used to study the changes in the fatty acid composition of the sum of the blood serum and erythrocyte membrane lipids in healthy male volunteers under the conditions of simulation in the ground-based hyperbaric set of long dives at depths of up to 350 m in the oxygen-helium and oxygen-neon media and in the readaptation(More)
Ten subjects (from 27 to 41 years) have been participated in 32 experiments. They were decompressed from ground level to 40-35 kPa in altitude chamber when breathed 100% oxygen by mask and performed repeated cycles of exercises (3.0 Kcal/min). The intervals between decompressions were 3-5 days. Plasma lipid and erythrocyte membrane fatty acid composition(More)
Gas-liquid chromatogrophy was used to study the skin and sebum cutaneum of 6 male test subjects (aged 45-55) before and after 30-day enclosure. The greatest changes were seen in the composition of free fatty acids of lipids of the facial skin (increase of palmito-oleic acid). The lipid composition of the sebum cutaneum of the healthy subjects differed from(More)
Investigations of the bone system and body composition in Mars-500 test-subjects (prior to and on completion of the experiment) involved dual-energy X-ray absorptiometry (DXA) using the HOLOGIC Delphy densitometer and the protocol performed to examine cosmonauts. Bone density of lumber vertebrae and femoral proximal epiphysis, and body composition were(More)
Nine healthy test subjects divided into Group A and Group B were bed rested (with the head down at -5 degrees) for 370 days. Group A subjects exercised from the beginning of the study while Group B subjects began exercising only 120 days after. During the study prostaglandins PGE and PGF2 alpha in serum and fatty acids in serum and erythrocyte membranes(More)
Gas chromatography was employed to study effects of sodium hydroxybutyrate (GHBA) and normobaric hyperoxia on the fatty-acid composition of total lipids of blood plasma and erythrocyte membranes in 5 normal male volunteers in the baseline data collection period and during 14-d bed rest. Both in plasma and erythrocyte membranes saturated palmitic acid was(More)
The effect of 120-day head-down tilt on the lipid spectrum of blood serum was investigated. By thin-layer and gas liquid chromatography lipids (total lipids, phospholipids, cholesterol and its esters, nonesterified fatty acids, triglycerides) and higher fatty acids were identified. It was found that cholesterolemia increased at the expense of the ester(More)
The effect of prolonged storage at the temperature 20 +/- 5 degrees C and relative humidity 70-80% on the freeze-dried food products packed in a three-layer polymer was investigated. The organoleptic parameters, fat content and fat physicochemical properties were determined in the freshly prepared foods and foods stored for 6, 10 and 14 months. The fat(More)
