TBW

The total fluid and sodium removal were measured. The bioimpedance analysis was employed to assess the extracellular water ( ECW), intracellular water ( ICW) and total body water ( TBW).

测定患者的总液体和钠的清除，以及测定患者的细胞外液（ECW）、细胞内液（ICW）、总体液量（TBW）、及相关资料。

This study aimed at detecting SSR markers linked to the resistance genes of TBW so as to facilitate the molecular marker-assisted breeding of tobacco varieties resistant to TBW.

本研究旨在检测与烟草青枯病抗性基因连锁的SSR标记，以期为烟草青枯病抗性的标记辅助育种提供技术手段。

The measurement of total body water ( tbw) by gc/ ms

人总体水的GC／MS法测定

Result The difference of total fluid and sodium removal, blood pressure were statistically significant between the three groups: the more severe the peripheral edema, the higher the total fluid and sodium removal, the higher blood pressure, the higher ECW and TBW.

结果3组患者水盐的排出和血压有统计学差异：水肿程度越重的患者，其总液体的清除和总钠的清除量越多，血压越高ICW和TBW越高。

ECW/ total body water ( TBW) was significantly lower and ICW/ TBW was significantly higher after hemodialysis than those before hemodialysis and at intervals of hemodialysis ( P

与透析前和透析间期比较，血液透析后ECW/机体总水量（TBW）降低，ICW/TBW升高，差异均有统计学意义（P

Total body TBW, ECM, clinical chemistry index, immune index, intestine mucosa penetrability were determined in every case before and after TPN.

对所有患者分别在接受全胃肠外营养治疗前、后测定身体总含水量和细胞外液量、临床生化指标、免疫指标和肠黏膜通透性。
