Iron absorption. Measurement of ingested iron59 by a human whole-body liquid scintillation counter.
The availability of radioactive isotopes of iron led to the development of reliable methods of studying iron kinetics (1), but the absorption of iron by the gastrointestinal tract was still determined indirectly by the amount of unabsorbed iron excreted in the stools or by quantification of isotopic iron incorporated into hemoglobin (2-7). The availability of a whole-body counter in a clinical ...
متن کاملMeasurement of Strontium-90 in the Persian Gulf Fish by Extraction Chromatography with Sr-resin and Liquid Scintillation Counter
Background: Despite its beneficial effects on human life, the nuclear industry has its own risks. Strontium 90 (90Sr) is one of the most dangerous radionuclides produced by the uranium 235 fission, and replaces the bone calcium in the human body, which causes cancer. Ensuring the safety of nuclear facilities to protect employees, people and the environment is among the main goals of nuclear saf...
متن کاملAbsorption of therapeutic preparations of iron measured with a whole body counter.
The Oxford Whole Body Counter was used to measure absorption from various therapeutic preparations of iron in five groups of subjects. Succinic acid enhanced absorption of iron when added to a solution of ferrous fumarate, but not when given with tablets of ferrous fumarate or ferrous sulphate. Ferrous fumarate plus ascorbic acid was absorbed better than ferrous fumarate alone but no better tha...
متن کاملMeasurement of blood and iron loss in colitis with a whole-body counter.
Estimation with a whole-body counter of the fall in total body radioactivity due to loss of parenterally administered (59)Fe has been used to measure blood loss in 17 patients with ulcerative colitis. It was shown that blood loss was related to the activity of disease as judged by sigmoidoscopic changes and less obviously to the extent of involvement of the colon. Blood losses of 50 to 150 ml p...
متن کاملDetermination of vitamin B 12 absorption by a simple whole body counter.
This paper reports the results of estimating vitamin B(12) absorption by whole body counting in patients without known gastrointestinal disorder, and in patients with pernicious anaemia, idiopathic achlorhydria, achlorhydria following gastric operations, and various forms of small intestinal disease. Patients with pernicious anaemia absorbed less than 30% of the test dose; they could be disting...
