1α-hydroxycholecalciferol and 25-hydroxycholecalciferol in renal bone disease

Calcified Tissue Research, 1975
The better control of calcium-phosphate homeostasis in uremic and chronically hemodialysed patients by the use only of phosphate binders, oral calcium supplement, high dialysate calcium, and/or more frequent dialysis, has considerably improved the course of renal osteodystrophy.

25-Hydroxycholecalciferol in experimental osteoporosis

Clinical Rheumatology, 1985
The authors, using the experimental pattern of bone rarefaction induced by a low calcium diet, tried to determine if 25-hydroxycholecalciferol, administered at doses and according to procedures similar to those used in osteoporosis, might interfere in such a process of rarefaction.

In vitro production of 25-hydroxycholecalciferol

Biochemical and Biophysical Research Communications, 1969
Abstract The metabolism of vitamin D3 to its biologically active form, 25-hydroxycholecalciferol, has been investigated in perfused rat livers and in rat liver homogenates. In both systems, significant conversion of vitamin D3 to 25-HCC was observed, supporting earlier data which indicate that the liver is the major, if not the only, site of ...

25-Hydroxycholecalciferol Metabolism in Hypophysectomized Rats*

Endocrinology, 1978
The metabolism of 25-hydroxycholecalciferol (25-(OH)Da) was investigated in vitamin D normal rats, 4 weeks after hypophysectomy. Compared to sham-operated controls, these animals were hypophosphatemic and their parathyroid glands were significantly smaller than normal. Eighteen hours after ip injection of a single dose of tritiated 25-(OH)D3 (50 pmol),

Synthesis of [26,27-3H]-25-hydroxycholecalciferol

Analytical Biochemistry, 1971
Abstract [26,27- 3 H]-25-HCC has been chemically synthesized. This preparation is radiochemically pure and has a specific activity (180,000 dpm/IU, 1.3 Ci/mmole) high enough to permit experiments with 0.025 μg of 25-HCC/rat. This preparation is biologically as active (52 IU/μg) as either isolated or synthetic 25-HCC in curing rickets in rats.

INTESTINAL ABSORPTION OF 25-HYDROXYCHOLECALCIFEROL

The Lancet, 1974
Abstract 25-hydroxycholecalciferol (25-H.C.C., Summary 25-OHD 3 ) was administered orally in a single dose of 10 μg. per kg. body-weight to twelve healthy volunteers and to ten patients with disordered calcium metabolism and/or gastrointestinal function.

Measurement of Plasma 25‐Hydroxycholecalciferol in Man

European Journal of Clinical Investigation, 1972
Abstract. A radio‐ligand assay for the measurement of 25‐hydroxycholecalciferol (25‐OH D3) in human plasma has been devised. Three ml of plasma, with 25‐hydroxychole‐calciferol‐26, 27‐H3 (3H‐25‐OH D3) added for recovery, was extracted and purified by thin‐layer chromatography. The plasma from an osteomalacic man, diluted 1 to 800, was used as a source
