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 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 ...

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 ...

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).

Implementation of a Water Compensator for Total Body Irradiation
IEEE Transactions on Biomedical Engineering, 2005This paper presents the design, implementation, and testing of an integrated system for improving dose homogeneity in total body irradiation (TBI). TBI is a radiation therapy technique that consists in delivering a uniform X-ray dose to the entire body of the patient. Because of variations in patient's tissues thickness and density, achieving a uniform

Total Body Water and Water Turnover in Sheep and Deer
American Journal of Veterinary Research, 1970SUMMARY The total body water and body water turnover in Columbian black-tailed deer (Odocoileus hemionus columbianus) and domesticated sheep (Ovis aries) were compared in winter and summer by testing with tritium oxide (TOH). There was a significant difference in water turnover in both species when data obtained in the winter were compared with those ...

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 ...

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 ...

RATE OF DISTRIBUTION OF ETHANOL INTO THE TOTAL BODY WATER
American Journal of Therapeutics, 1995Nonequilibrium distribution of ethanol in the total body water (TBW) has implications for understanding gross intoxication seen after rapid consumption of alcohol and for certain new clinical monitoring methods where ethanol is used as a tracer. We studied the rate of distribution of ethanol into the TBW from the concentration--time profiles in whole ...

Determination of total body water by deuterium NMR
The American Journal of Clinical Nutrition, 1987A new deuterium nuclear magnetic resonance (2H NMR) method is described for determining total body water in humans. The method has been validated against a standard infrared absorption (IR) procedure using a tracer dose of deuterium oxide (2H2O) of approximately 10 g for each human subject.
