Total body water measurement in renal insufficiency
Pediatric Nephrology, 1996Total body water was measured in 15 children with renal insufficiency (glomerular filtration rate < 25 ml/min per 1.73 m2) using deuterium oxide dilution. Total body water was also measured using bioelectrical impedance and skinfold anthropometry in the same 15 children.

Measurement of Total Body-water with Urea
Nature, 1952TOTAL body-water in the intact animal is usually measured by dilution methods. In these, determinations are made of the volume of fluid in which a known amount of some freely-diffusible substance distributes itself in the body. Urea which, with the exception of some of the fluids of the kidney and the renal veins and the possible exception of the ...

Changes in Total Body Water During Spaceflight
The Journal of Clinical Pharmacology, 1991This experiment represents the first time that it has been possible to measure a body fluid compartment by direct means during spaceflight. Based on the results observed in the five crewmen in this study, it is concluded that TBW decreases by 3.4% after 1 to 3 days of exposure to microgravity in the Space Shuttle.

Total body water in farm animals
American Journal of Physiology-Legacy Content, 1964Dilution procedures with tritium and labeled and unlabeled pyrazolones were used to measure total body water in 89 swine, 99 cattle, and 170 sheep, grouped for convenience of presentation into two age-weight groups. Mean plasma disappearance rates for injected antipyrine were 45, 23, and 28%/hr, and loss of antipyrine reversibly bound to plasma ...

Klinische Wochenschrift, 1979
Extracellular water (EWC; 82-bromide), total body water (TBW; 3-THO), intracellular water (ICW = TBW-ECW), plasma volume (PV; 51-Cr), and total body potassium (TBK; 40-K) were studied in patients with cirrhosis of the liver (n = 12) and in controls (n = 12).

Body Weight, Total Body Water and Hematocrit in Diarrheic Piglets
Journal of Animal Science, 1986Piglets aged 12 to 72 h in which diarrhea had been induced by enteric Escherichia coli infection or sucrose gavage were studied with respect to body weight, total body water concentration (determined by tritiated-water dilution) and hematocrit. Sucrose-induced diarrhea reduced body weight by 13 to 17%, and E. coli diarrhea, by 8 to 9%.

In this chapter, the modifications that occur in water distribution from the fetus to the newborn, focusing on the neonatal period, are reviewed. This is a critical period in life as the newborn infant has to adapt itself to a new environment. The main water compartments, intra- and extracellular, undergo changes throughout infancy, with an increase in

We hypothesized that investigators could assess bone mineral content (BMC), total body mineral (M), and protein (P) from body water (W) and density (DB) based on the theory of W. E. Siri (Advances in Biological and Medical Physics, 1956, p. 239–280 and Techniques for Measuring Body Composition, 1961, p. 223–224) for body composition analysis.

Changes in total body water with age
The American Journal of Clinical Nutrition, 1989Extensive cross-sectional studies demonstrate a diminution of total body water in elderly and very old subjects. These findings are supported by less extensive longitudinal studies. Cross-sectional studies indicate that the decrease in total body water is mainly due to decreased intracellular water, but this is not supported by the findings of ...

Food / Nahrung, 1991
AbstractBody composition data estimated for normal young, normal adult, and adult obese Wistar rats by a tritiated water (THO) dilution procedure (b. wt. range 119–237 g, n=31; 305–597 g, n=43; 274–381 g, n=6) were compared with the results of whole body analysis.As for the predicted total body lipid (TBL), the content was calculated from the virtual ...
