[Cytogenetic studies of human blood lymphocytes in vivo in a 7-day experiment with immersion].

: The investigation had the goal to fulfill in vivo cytogenetic studies of blood lymphocytes of human subjects in a 7-d experiment with "dry immersion". Blood was sampled from 10 subjects prior to and on completion of the experiment. Analysis of chromosomal aberrations in blood lymphocytes after exposure to simulated microgravity did not reveal statistically reliable chromosomal alterations in comparison with spontaneous levels.
