Total exchangeable potassium in response to amiloride.

Measurement 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...

[Total exchangeable sodium, exchangeable potassium and total body water in some endocrine diseases].

概要 諸種 内分 泌疾患 々者についてtotal exchangeable sodium (Nae)お よびpotassium (Ke)を 測定 し,得 た成績 をtotal body water (TBW)か ら算出 したlean body massと の関連 において比較 した. 原発性 アル ドス テロ ン症ではNaeは 著増 し, Keは 減少 していた.一 方続発性 アル ドステ ロン症を伴な つた腎尿 細管 性 アシ ドージスでは, Naeお よびTBWの 増加は な くKeは 著減 していた. Cushing症 候 群 ではKeは 減少 していた. Addison病 では予想 されたNaeの 減少, Keの 増加 はみ られなかつた.褐 色 細胞腫 ではNae, Keお よびTBWは いずれ も正常 であつた.甲 状線機能亢 進症 ではNae増 加, Ke減 少 の傾 ...

Whole body potassium and total exchangeable potassium in elderly patients with cardiac-failure.

Body potassium status of patients with cardiac failure may be estimated by a number of methods, but increasing reliance is being placed upon radioisotope dilution with 42K which measures the total exchangeable potassium. Total exchangeable potassium comprises between 86 per cent and 97 per cent of whole body potassium in healthy subjects. We have measured total exchangeable potassium in 22 oede...

Total exchangeable potassium and chloride and total body water in healthy men of varying fat content.

The Relationship of Total Exchangeable Potassium and Chloride to Lean Body

Potassium has long been known to be almost completely confined to the intracellular compartment, and the neutral fat present in muscle has been shown to have a low chloride content (1). It seemed probable, therefore, that the error associated with predictions of total exchangeable electrolyte from total body weight would diminish if the variable of depot fat was eliminated by the use of lean bo...
