A whole body counter for serial studies of total body potassium.
1. The use of a whole body counter in total body potassium estimations is described. The accuracy and value of the counter in measuring serial changes in total body potassium was assessed. 2. Serial study of twelve normal subjects at varying intervals revealed a normal variability in total body potassium of up to 1.23% (4-weekly measurements over 3 months). The error involved in counting statis...
متن کاملBody cell mass measured by total body potassium in normal-weight and obese men and women.
OBJECTIVE Total body potassium (TBK) concentration is linearly correlated with the size of the body cell mass (BCM). The aim of this study was to compare BCM in normal-weight and obese individuals. METHODS 271 individuals (207 males, 64 females), 20 to 67 years of age, participated in this study. Subjects were separated by body mass index (BMI): BMI < 25 kg/m(2) (BMI-L) and BMI > 25 kg/m(2) (...
متن کاملRheological properties of blood after whole body gamma-irradiation
Background: The study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. This work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. The applied shear rate was from 12 to 375 s-1. Low shear viscosity (up to 100 s-1) depends mainly on the erythroc...
متن کاملMathematical Calibration of a Whole-Body Counter
This paper describes the mathematical efficiency calibration of the whole-body counter at Forschungszentrum Jülich using Monte Carlo codes and mathematical anthropomorphic phantoms. As a prerequisite for the Monte Carlo simulations a precise model of the 4 high-purity germanium (HPGe) detectors had to be developed. Because the technical data provided by the manufacturer were not sufficient for ...
متن کاملTotal body potassium falls with age.
1. Plasma volume, 24 h urine sodium and total body potassium were similar among 89 previously untreated patients with mild hypertension and 89 control subjects matched for age and sex. 2. Total body potassium correlated with renin activity in both hypertensive patients and controls. 3. Renin activity and total body potassium fell significantly with age in both groups. 4. The relationship betwee...
