飞行员Coriolis加速度刺激下血浆激素水平的变化

为探讨Ｃｏｒｉｏｌｉｓ加速度刺激下，健康飞行员与有晕厥史飞行员（立位耐力阳性者）某些内分泌激素的区别，选健康飞行员与有晕厥史的飞行员各１２名，分别间隔３～４ｍｉｎ间断累加地给与３．７５π＾２ｃｍ／ｓ＾２，５．００π＾２ｃｍ／ｓ＾２，６．２５π＾２ｃｍ／ｓ＾２的Ｃｏｒｉｏｌｉｓ加速度刺激，用放射免疫法测定血管紧张素－Ⅱ，醛固酮，皮质醇，胰岛素，胃泌素，结果显示：两组飞行员在Ｃｏｒｉｏｌｉｓ加速度刺激

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.
