Pediatrics, 1951
Total body water was determined in 24 normal infants and children by deuterium oxide dilution and by the antipyrine method. A micro-modification of the antipyrine method is described. Agreement between the two methods for determining total body water was good.

Total body water and total body potassium in anorexia nervosa
The American Journal of Clinical Nutrition, 1984In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with

Total body water estimated by measuring total-body electrical conductivity
The American Journal of Clinical Nutrition, 1988A second-generation total-body electrical conductivity (TOBEC) instrument for adults (HA-2) was evaluated against isotope dilution of 2H and 18O for its ability to estimate total body water (TBW) in 20 healthy adults. The highest correlation coefficient (0.997) and the lowest standard error of the estimate (0.68 kg) were obtained using the first (FC0 ...

GASTROINTESTINAL LAVAGE REDUCES TOTAL BODY WATER
Australian and New Zealand Journal of Surgery, 1997Background: The aim of this study was to measure changes in total body water (TBW) in surgical patients after gastrointestinal lavage.Methods: In a prospective, controlled study we used bioelectrical impedance to calculate the change in TBW in two groups of general surgical patients in the pre‐operative period: the colonic lavage group consisted of ...

Correlation of Total Body Potassium with Body-Water
Nature, 1956THE total potassium content of the human body1 is of considerable interest from the point of view of physiology and in connexion with the clinical study of certain muscular disorders. Recently it has acquired additional interest because the radioactivity of naturally occurring potassium-40 in the body constitutes the principal ‘background’ in some 4π ...

Total Body Water and Total Body Solids in Cattle Affected with Ostertagiasis
British Veterinary Journal, 1965SUMMARY Using tritiated water, measurements were made of total body water and total body solids in cattle with type I and cattle with type II ostertagiasis ‡ . The same measurements were carried out on uninfected control animals of appropriate age. When expressed as a percentage of body weight the body solids were unaltered in type I ostertagiasis ...

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 ...
