Simultaneous free and bound radioactive vitamin B-12 urinary excretion test.

چکیده
The absorption of vitamin B(12) following the simultaneous administration of (58)Co B(12) and a complex of (57)Co B(12) with human gastric juice was assessed by measurement of urinary excretion of radioactivity. Sixteen control subjects, 13 patients with pernicious anaemia, and four who had had total gastrectomy were studied. The method proved a reliable means of detecting those with intrinsic factor deficiency.

متن کاملThe urinary excretion of assayable vitamin B12 and radioactivity after parenteral 58Co B12 in man.
Evidence is presented that after injection of radioactive vitamin B(12) in man, there is a close correlation between the amount of radioactivity excreted and the amount of assayable vitamin B(12) excreted, and thus that the amount of radioactivity excreted is a true measure of the vitamin B(12) excreted. The possible reasons for this occurrence are discussed and it is suggested that in the body...
متن کاملStudy on the effect of high calcium intake on serum protein bound iodine and urinary excretion of iodine
Iodine deficiency remains a major health problem in the world, including some parts of Iran. It has been recognized that there is usually a close and inverse relationship between iodine in the soil and water and presence of endemic goiter. Calcium has been suggested as one of goitrogens, though the definite role, extent and mechanism particularly in human have not been studied. Serum protein-...

STEELMAN T HE NORMAL HUMAN INTESTINE can absorb significant amisounts of the usually ingested quantities of vitamnin B12 only in the presence of intrinsic factor. In recent years three different tests using orally admimmistered, Co#{176}#{176}-labeled vitamin B12 have beets proposed for the estimation...
متن کاملSerum vitamin B12 in renal failure.
The serum vitamin B(12) level was abnormally high in 14 out of 32 cases of renal failure. This was probably due to impaired excretion of the vitamin, but the results of measurements of the rate of excretion of radioactive vitamin B(12) did not provide unequivocal evidence on this point; other possible explanations are discussed. Renal failure must be added to the causes of high serum B(12) levels.
