Effects of ginger on motion sickness and gastric slow-wave dysrhythmias induced by circular vection.
Ginger has long been used as an alternative medication to prevent motion sickness. The mechanism of its action, however, is unknown. We hypothesize that ginger ameliorates the nausea associated with motion sickness by preventing the development of gastric dysrhythmias and the elevation of plasma vasopressin. Thirteen volunteers with a history of motion sickness underwent circular vection, durin...
متن کاملCoupling and propagation of normal and dysrhythmic gastric slow waves during acute hyperglycaemia in healthy humans.
Acute hyperglycaemia in healthy humans disrupts slow wave rhythm similar to that observed in diabetic gastropathy, but hyperglycaemic effects on regional dysrhythmias, power, coupling and propagation are unexplored. Using mucosal mapping, we aimed to demonstrate that hyperglycaemia elicits region-specific tachygastria and evokes slow wave uncoupling between adjacent regions. Catheters with bipo...
متن کاملDetection of gastric slow wave propagation from the cutaneous electrogastrogram.
The gastric slow wave is originated in the proximal stomach and propagates distally toward the pylorus. It determines the maximum frequency and propagation of gastric contractions. The aim of this study was to detect the propagation of the gastric slow wave from the surface electrogastrogram (EGG). The study was performed in 11 healthy subjects of normal weight. Gastric myoelectrical activity w...
متن کاملOrigin and propagation of human gastric slow-wave activity defined by high-resolution mapping.
Slow waves coordinate gastric motility, and abnormal slow-wave activity is thought to contribute to motility disorders. The current understanding of normal human gastric slow-wave activity is based on extrapolation from data derived from sparse electrode recordings and is therefore potentially incomplete. This study employed high-resolution (HR) mapping to reevaluate human gastric slow-wave act...
