Scopolamine (1.0 mg) and d-amphetamine (10 mg) were administered alone and in combination to 16 subjects (medical students), randomly assigned to testing sessions in a fully crossed-over (Latin square) within-subjects design. After being practiced to stability, 9 performance tests from a menu of portable microcomputer-based tests were administered(More)
This study was designed to evaluate the antimotion sickness activity of ginger root (Zingiber officinale) and to characterize the effects of ginger on gastric function. Twenty-eight human volunteers participated in the project. Subjects made timed head movements in a rotating chair until they reached an endpoint of motion sickness short of vomiting (malaise(More)
The vestibular, cerebellar, and reticular systems are central in importance, in motion sickness and habituation, to the effects of motion. Nuclear medicine single photon emission computed tomography (SPECT) studies of cerebral blood flow and power spectral electroencephalographic recordings during motion sickness were used to determine alterations in the(More)
Many interventions generated by research with the aim of improving the nutritional status of livestock in developing countries have failed to realize their apparent potential when implemented on farms. It is now widely accepted that this is because farmers try to meet a wide range of objectives in feeding their animals. Their decision making can be(More)
This project has employed a computerized pursuit meter which has a high correlation with operational performance (2) to test the principal antimotion sickness drugs. Proficiency scores on the pursuit meter task were improved over placebo scores in subjects with d-amphetamine 10 mg and 5 mg, the combination of promethazine 25 mg plus scopolamine 0.4 mg with(More)
The possible influence on operational proficiency of the side effects of the anti-motion sickness drugs was investigated using a computerized pursuit meter as the test device. The medications and doses tested were scopolamine (Hyoscine) 0.25 mg and 0.50 mg oral doses, promethazine (Phenergan) 25 mg oral and 25 mg I.M. doses. Combinations of promethazine 25(More)
UNLABELLED Eight subjects, male and female, were rotated using the step method to progressively increase the speed of rotation (+2 rpm) after every 40 head movements to a maximum of 35 rpm. The end-point for motion sickness was the Graybiel Malaise III total of symptoms short of frank nausea. The drug treatments were placebo, scopolamine 0.6 mg and 1 mg,(More)
