| objective: In order to further explore mineral metabolic change rule in seasickness and its adaption process, the present study observe the metabolic changes of potassium, sodium, magnesium, iron and zinc in seasickness and its adaption process.. Methods: we screened seasickness susceptible rats then randomly divided into seasickness control and the simulation seasickness groups . determined the rats mineral substance to take in. in the excretion quantity as well as the blood plasma and the internal organs mineral substance content with atoms absorptions spectrophotometer. Results: When seasickness occurred, decrease of water intaken might give rise to intake reduction of elements from water but the intakes of these elements from diet has no obvious change. Elemental loss except iron in feces was also no big change but there was a tendency that contents of all elements in urine were increased. At the early stage of seasickness, mineral contents in plasma and brain, kidney and liver of rats show a decrease tendency, in which potassium and iron content in plasma and iron as well as zinc in brain were significantly decreased. But after a week the degree of reduction tended to be less and at the same time the contents of potassium and sodium in plasma were obviously elevated. After the seasickness adaptation, most elements were restored to normal levels.. |
