Total body sodium by whole body neutron activation in the living subject: further evidence for non-exchangeable sodium pool.
The fundamental pathological processes of diseases involving generalized disturbance of skeletal mineralization are ill understood , and treatment is often unsatisfactory. Radiographic techniques are widely used in the diagnosis and management of bone disease. Such techniques are fundamentally dependent on the radio-opacity of skeletal calcium. The most careful radiological assessments may not ...
متن کامل[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 ...
متن کاملShielding studies on a total-body neutron activation facility
Background: Prompt gamma neutron activation analysis (PGNAA) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. Also it is a valuable diagnostic tool for total body elemental measurements. 252Cf and 241Am-Be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...
متن کاملConcurrent estimation of total body and exchangeable body sodium in hypertension.
1. Total-body neutron-activation analysis in vivo was carried out in 11 hypertensive subjects to measure simultaneously the total body content of sodium, chlorine, calcium, phosphorus and nitrogen. 2. There was a highly significant correlation between total body sodium measured by activation analysis and total exchangeable sodium measured by a standard isotope-dilution technique (r = 0.92, P le...
متن کاملTotal body water, total exchangeable sodium and related variables in the Ghanaian.
1. Standard radioisotope dilution techniques employing [3H]water and [22Na]sodium chloride have been used to determine the total body water and total exchangeable sodium of 20 male and 10 female normal Ghanaians (Africans) aged 19--25 years. 2. Lean body mass and total body fat are calculated as a percentage of body weight; the total exchangeable sodium values have been expressed in relation to...
