Six male volunteers for dry immersion (DI) simulating microgravity effects in the human body were subjects in the study on the evacuation function of the gastrointestinal tract (GIT). The investigation was aimed to evaluate liquid food evacuation from the stomach (the 13C-acetate test) and time of chymus orocecal transit (the H2-inulin test). The(More)
The functioning of the digestive system was investigated in ten volunteers after a seven-day dry immersion (DI). The experimental conditions were found to raise the secretory activities of the stomach, pancreas, and liver and to increase the spectral indices of the gastrointestinal tract’s (GIT) electrical activity against the background of an increased(More)
Ultrasound investigations (USI) of the liver, organs and vessels of the gastroduodenal area, as well as blood biochemistry, were performed in two groups of male volunteers on the 4th day of their stay in the conditions of “dry” immersion with and without the application of countermeasures, including the support load imitator (SLI) or high-frequency(More)
Ultrasonic examinations of eight male volunteers during bed rest in the antiorthostatic position (ANOP) at–15° showed plethora in the venous system of the abdominal cavity and slow blood flow through the liver with no effect on biochemical parameters. The 13C-methcetine breath test (13C-MBT) with 100 mg of 13C-methoxymethacetine showed diminution of the(More)
