Endocrine-metabolic appraisal was made by means of urinalysis for all participants (two crews of 5 men each) in the first nonstop, transatlantic helicopter flight. Serial urine specimens were analyzed for epinephrine, norepinephrine, 17-hydroxycorticosteroids (17-OHCS), urea, creatinine, phosphorus, magnesium, potassium, and sodium. Nonspecific stress was evident, as flight caused a 143% gain in epinephrine, a 25% gain in urea, and a 51% reduction in the norepinephrine/epinephrine ratio. It also modified the circadian trends for 17-OHCS and phosphorus. The interindividual endocrine-metabolic variability was high. (Author)
