cortodoxone and Motion-Sickness

In order to grade motion sickness objectively, the following 11 adrenal hormones were investigated in subjects with different motion sickness susceptibility: Aldosterone, corticosterone, 11-deoxycorticosterone, progesterone, 17-OH-progesterone, 11-deoxycortisol, cortisol, cortisone, testosterone, androstendione, dehydroepiandrosterone sulfate. Motion sickness was induced by the coriolis effect on a rotary chair. Both severe kinetosis after short rotation time and mild motion sickness after 30 min of rotation occurred together with small hormonal changes. Androstendione and 11-deoxycortisol appear to be sensitive indicators of motion sickness if the rotation time is taken into consideration. A significant increase of all hormones except progesterone, cortisone, testosterone, and dehydroepiandrosterone sulfate was observed when pronounced malaise had come after a long rotation stress (24.6 min). The changes in plasma aldosterone concentration appeared to correlate with time only. The present study demonstrates that hormonal analysis can be helpful in estimating the degree of motion sickness.
