| Research Abstract |
For a rapid and efficient rehydration, ingested fluid should stay in plasma for a long time after drinking. We developed a novel and precise metabolic cage for rats to analyze urine volume after drinking. Urine volume was about 50% lower after drinking milk compared to water sports drink for 4 hr. The difference of urine volume among drinks was explained by two equivalent fractions, such as high molecular and low molecular fraction. Plasma volume was sustained on higher level after drinking milk and which can be elucidated by plasma sodium level.
