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.

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 ...

Serum 25-Hydroxycholecalciferol in Uremia

Nephron, 2008
Serum 25-hydroxycholecalciferol (25-OH-D₃) was determined in 20 normal persons and in 50 patients with renal failure. Low serum levels were found in patients with markedly impaired renal function while patients on chronic hemodialysis exhibited normal values.

1α‐Hydroxycholecalciferol in the Treatment of Hypoparathyroidism

Acta Medica Scandinavica, 1977
ABSTRACT In two patients (father and daughter) with idiopathic hypoparathyroidism, one of whom was resistant to the action of vitamin D2 and AT‐10, lα‐hydroxycholecalciferol (lα‐(OH)D3) in doses of 2–5 μ//day restored the serum calcium concentration to the normal range.

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.

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

TREATMENT OF OSTEOPOROSIS OF AGEING WITH 1α-HYDROXYCHOLECALCIFEROL

The Lancet, 1975
Seven patients with osteoporosis of ageing were treated with synthetic 1alpha-hydroxycholecalciferol (1alpha-H.C.C.) for 3-4 months. The compound was given at a daily oral dose of 2 mug together with an oral supplement of 1 g of calcium. Clinically there was a striking improvement in the patients' physical fitness.

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.
