Measurements Of Total Body Potassium Research Articles

Studies on total body potassium in malnourished infants. Factors affecting potassium repletion.

1. Serial measurements of total body potassium were made in children while they were malnourished and as they recovered. Initially, there was a low total body potassium which rose slowly and reached the normal levels of 45 m-equiv./kg at 3–4 weeks after admission to hospital.2. The early stages of recovery were divided into three phases. In the first 5 days of treatment, retention of potassium served to correct a true potassium deficiency and the amount of potassium retained during this phase was related to the initial level of total body potassium. There was no relationship between serum potassium and total body potassium. There was indirect evidence that antecedent diarrhoea was an important factor in the production of potassium depletion.3. In the next phase—the lag phase—potassium was retained in relation to deposition of new body tissue.4. In the phase of rapid growth, potassium was also retained in the amount appropriate for deposition of new tissue.5. After the repair of the acute potassium depletion, potassium retention was always correlated with the protein intake.

Total potassium measurement by anthropogammametry (whole-body counting): various applications in internal pathology

SummaryThe whole Body Counter of Liege University permits, by counting the naturally occurring ,40K isotope, the measurement of total body potassium (which can be practically considered as the intracellular potassium content) in human subjects. The accuracy of the measurements is 5 % for a counting time of 200 seconds. Normal values have been checked by the measurements of a great number of healthy individuals: regression equations have been computed according to age and weight. The fluctuations of normal values, when related to homogeneous groups, are rather small, and the meaning of pathological results seems unequivocal. The preliminary findings have confirmed an important decrease of body potassium in amyotrophy, cirrhosis of the liver, obesity and cardiac failure. A less pronounced, but statistically significant decrease was also found in equilibrated diabetes, essential hypertension and renal failure. Longitudinal studies have shown parallelism between the body potassium content and clinical evoluti...

LEAN BODY MASS AND FAT IN OBESE CHILDREN

Measurements of total body potassium in obese children were made in the whole body scintillation counter, and from this value lean body mass was calculated, and then fat by difference. A series of normal children was available for comparison. There was a good correlation between total body fat and relative body weight, abdominal circumference, and buttocks circumference, and a fair correlation with triceps skin-fold thickness. Although the series is a small one, it suggests that there are two types of obesity in childhood. The first is characterized by increased LBM in addition to fat, by a tendency to tallness and advanced bone age, and to have been overweight since infancy. The second group shows no increase in LBM; these subjects tend to have a normal bone age, to be of average height, and the majority have become obese during the childhood years.
