Abstract:

Urinary excretion of 17-OHCS, corticosterone-like hormones, and catecholamines was investigated in pilots during prolonged experiments in a two-man space cabin simulator. The experimental profiles were 1 two 17-day experiments at ground level 2 two 14-day experiments at 27,000 feet and 3 four 17-day experiments at 33,500 feet. In the latter two groups, the atmosphere was essentially 100 O2. The hormone parameters indicate that conditions imposed by the experimental procedures were no more stressful to the subjects than undergoing extensive medical examinations, as observed from pre-experimental and postexperimental values. The only significant trend was the continuous linear increase in the excretion of corticosterone-like hormones. Extraordinary occurrences in the simulator were correlated with increased catecholamine and steroid excretion. The correlation coefficients and the analyses of variance for the four hormone parameters were calculated and discussed. Author
