[Changes of plasma endocrine hormone in pilots under Coriolis acceleration].
Plasma endocrine hormones were studied in both 24 motion sickness (orthostatic intolerance) and healthy pilots. Coriolis acceleration of 3.75, 5.00 and 6.25 pi 2 cm/s2 were given with intervals of 3-4 min AT-II, insulin, cortisol, Aldosterone and gastrin were determined by radioimmunoassay. It was found that aldosterone, AT-II, gastrin increased with increase of coriolis acceleration in all pilots. (P < 0.05), but cortisol and insulin only increased in healthy pilots (P < 0.05). It suggests excitation of the autonomic nervous system might be insufficient in orthostatic intolerant pilots and that determination of endocrine hormones may be useful in the evaluation of autonomic nervous activities.
