Biochemical Status of Humans in Long Duration Space Flight (Biotest) - 02.25.15
Information Pending Science Results for Everyone
To better understand how humans adapt to microgravity, researchers measured hormonal, metabolic, and biochemical indicators on the ground and the final stages of long-term spaceflight. They found no changes in some types of hormones, such as those secreted by the adrenal cortex, which controls stress response. They did find changes in hormones that reflect an individual’s metabolism and activity, such as thyroid hormones. Some of the indicators varied depending on flight duration and crew member age. The data will be used to assess the physical state of crew members on long-duration space flights and help develop and improve diagnostic tools and preventive measures. Experiment Details

KV-03 container, Set of Plasma-03 consumables, Reflotron-4 pouch, Reflotron-4 set of accessories, Plasma-03 centrifuge, Plasma-03 set of accessories, Minicentrifuge M1100.
Taking blood samples for a study of biochemical regulation of body homeostasis during adaptation to weightless environment; a study of the role of hormonal mechanisms in the variations in the water-salt, lipid, and protein exchange; and for the selection of informative biochemical indicators to evaluate cosmonaut's health.
The received information on the metabolism state makes possible assessment of the cosmonauts' physical state throughout long-duration space flights and will be used as the basis for development and improvement of diagnostic and prophylaxis tools.^ back to top
