Body 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 کاملBody cell mass index in children: interpretation of total body potassium results.
Body cell mass (BCM) is a valuable measure of functional nutritional status in children. As BCM is related to body size, it is essential that BCM is adjusted for stature when interpreting BCM data in children. Our aim was to examine the relationship between height and BCM in healthy children to determine the power by which height should be raised to adjust BCM for stature. This cross-sectional ...
متن کاملTotal body potassium in cor pulmonale.
Total body potassium was measured in 12 patients with cor pulmonale, by determination of potassium-40, a naturally occurring radioisotope. In all subjects the observed value of total body potassium showed no significant depletion when compared with that predicted from height and age. All previous studies in similar groups of patients have been confined to the estimation of exchangeable potassiu...
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...
متن کاملMeasurement of Total Body Exchangeable Potassium
Studies were undertaken to appraise the cellular potassium status of children with the nephrotic syndrome, utilizing two techniques: Measurement of total body exchangeable potassium (Ke) by isotope dilution and determination of the potassium content of red blood cells by direct chemical analysis. The Ke values obtained on the nephrotic children are compared to similar data obtained on "hospital...
