Plasma thyroxine changes of the Apollo crewmenBlood drawn from Apollo crew members prior to the mission, at recovery, and postmission, was used to examine the effect Apollo mission activities have on thyroid hormone levels. At recovery, statistically significant increases in thyroxine and the free thyroxine index were found. Serum cholesterol and triglycerides were decreased. No change of statistical significance was found in the T3 binding percentage, total serum proteins, and albumin. We conclude that Apollo activities and environment caused the postmission increase in plasma thyroxine. The prolonged postmission decreases in serum cholesterol may be one result of the increased thyroxine activity.
