Six previously published animal studies of tumor production have been reviewed, in order to relate time interval between exposure to nickel and development of tumor formation. Biopsies at intervals before final tumor formation, in some of these exper

OBJECTIVE We wished to assess the effect of changes In the plasma concentration of 1,25-dihydroxyvitamin D on the plasma elimination half-time for 25-hydroxyvitamin D In man. DESIGN The turnover of 25-hydroxyvltamin D in plasma was Investigated after

1. The metabolism of an intravenous pulse dose of double-isotope-labelled cholecalciferol has been studied in control subjects with widely differing states of vitamin D nutrition and in patients with primary disorders of parathyroid function. 2. The

It has become obvious, from the elegant in vitro studies of Cohn et al. (3) and of others, that calcium may act at various steps in the biosynthesis, storage, degradation and secretory release of parathyroid hormone. It would be premature to attempt

1. The serum concentrations of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D were measured in 44 patients with primary hyperparathyroidism. 2. In 14 patients the serum concentration of 1,25-dihydroxyvitamin D was greater than normal (142–337 pmol

1. The elimination half-time of 25-hydroxyvitamin D in plasma was estimated after intravenous injection of the radioactively labelled metabolite in seven patients with primary hyperparathyroidism before and after excision of a parathyroid adenoma. 2.

Five patients with primary biliary cirrhosis and vitamin D deficiency (serum 25-hydroxyvitamin D less than 6 ng/ml) are presented. All patients had low serum 24, 25-dihydroxyvitamin D3 concentrations. Three patients had histological osteomalacia, neg

Biologic assay of the antiricketic activity in serum and tissues has been used, with concomitant measurements of intestinal net absorption of calcium, to study aspects of vitamin D metabolism in man. Patients with chronic renal failure appear to requ
