The present study investigated the effects of drinking milk or water before viewing an optokinetic rotation drum on the severity of motion sickness and abnormal gastric myoelectric activity.
There were 27 subjects who drank 300 ml of milk or water, or drank nothing, in three separate sessions with 2-d intervals between every two sessions. Subjects in each session then viewed a vertically striped optokinetic rotation drum for 16 min. Symptoms of motion sickness and electrogastrograms (EGGs) were measured.
Subjects reported no significant difference in symptoms of motion sickness among sessions of drinking milk, water, or nothing. EGG recordings indicated that subjects in sessions of drinking milk and water significantly increased normal gastric myoelectric activity at EGG 3 cycles per minute (cpm). Subjects in all three sessions increased abnormal EGG activity at 4-9 cpm during drum rotation period, however, the ratios of EGG 4-9 cpm of drum rotation and baseline periods were not significantly different among sessions.
These results demonstrated that drinking milk or water before viewing an optokinetic rotation drum exhibited no effect on the severity of symptoms of motion sickness and abnormal gastric myoelectric activity.
本研究调查了在观看视动旋转鼓之前饮用牛奶或水对晕动病严重程度及胃肌电活动异常的影响。
27名受试者在三个不同时间段分别饮用300毫升牛奶或水，或不饮用任何饮品，每两个时间段之间间隔2天。每个时间段的受试者随后观看垂直条纹视动旋转鼓16分钟。测量晕动病症状和胃电图（EGG）。
受试者报告称，饮用牛奶、水或不饮用饮品的时间段之间，晕动病症状无显著差异。EGG记录表明，饮用牛奶和水的时间段的受试者在每分钟3个周期（cpm）的EGG时，正常胃肌电活动显著增加。然而，在所有三个时间段中，受试者在鼓旋转期间每分钟4 - 9个周期时异常EGG活动均增加，不过各时间段鼓旋转期和基线期的EGG 4 - 9 cpm比率无显著差异。
这些结果表明，在观看视动旋转鼓之前饮用牛奶或水对晕动病症状的严重程度及胃肌电活动异常没有影响。
