肥胖病常伴细胞外液(ECW)部分的绝对和相对量增加,但长期体重下降对体液重新分布的影响尚不明确,至于减肥治疗能否使ECW减少也不清楚。取25位肥胖妇女(年龄36±8岁)作为实验组,另取26例非肥胖妇女(年龄36±13岁)作为对照组。两组的体重相差明显,但身长的差别不显著。实验前晚禁食,分别在减肥术前和术后6～12个月定期用~3H_2O稀释法测体液总量(TBW),用~(35)SO_4稀释法测ECW,用~(24)Na测可交换钠量(Nae),用总~(40)K测总钾量(TBK)。肥胖组妇女又分成两小组,计限制胃
The relative absolute and relative amounts of obesity associated with extracellular fluid (ECW) increase, but the effect of long-term weight loss on body fluid redistribution is unclear. It is unclear whether weight loss treatment can reduce ECW. Twenty-five obese women (age 36 ± 8 years) were selected as the experimental group, and another 26 non-obese women (age 36 ± 13 years) were taken as the control group. Body weight difference between the two groups was significant, but the difference in body length was not significant. The rats were fasted at night before the experiment and the total body fluid (TBW) was measured by ~ 3H_2O dilution method before and during 6 ~ 12 months postoperatively respectively. ECW was measured by ~ (35) SO_4 dilution method, Measured exchangeable sodium (Nae), with total ~ (40) K measured total potassium (TBK). Women in the obese group are divided into two groups, which limit the stomach
