The absorption of a pharmacological dose of vitamin D3 from two different lipid vehicles, peanut oil, containing long chain fatty acids, and a medium chain triglyceride was compared. Serial measurements of the serum concentration of vitamin D3 after

Ingested ethanol is mainly oxidized to acetaldehyde and acetate in the liver and oxidative metabolites of ethanol have been implicated in organ injury. More recently, fatty acid ethyl esters (FAEEs), non-oxidative metabolites of ethanol, have been sh

We have compared the effect of physiological and pharmacological concentrations of retinoids and 1,25(OH)2 vitamin D3 bound to their plasma transport proteins upon the proliferation and differentiation of HL-60 cells. Concentrations of chylomicron re

Assay conditions for the measurement of 25-hydroxyvitamin D3-24-hydroxylase activity in rat kidney mitochondria have been worked out. The product, 24,25-dihydroxyvitamin D3 was quantitated either by high pressure liquid chromatography or by isotope d

We describe a specific assay of 1,25-dihydroxy vitamin D3 in human serum, based on isotope dilution-mass fragmentography. We added [26-2H3]-1,25-dihydroxy vitamin D3 to a fixed amount of serum. The steroids were extracted with chloroform/methanol and

Using isotope dilution—mass fragmentography as assay technique, it was shown that highly purified preparations of cytochrome P-450 from rat liver microsomes catalyzed 25-hydroxylation of vitamin D 3 when combined with NADPH-cytochrome P-450 reducta

Summary A cytochrome P-450 fraction, containing vitamin D 3 25-hydroxylase activity after reconstitution, was prepared from rat liver microsomes. The 25-hydroxylase activity increased considerably upon purification. A protein fraction isolated from t

The synthesis of 25-hydroxy-[26-2H3]vitamin D3 is described. A fixed amount of this compound (usually 250 ng) is added to a fixed amount of serum (usually 2.5 ml) and the mixture is extracted with a chloroform/methanol mixture. The extract is chromat

Normocalcaemic male stone formers, 31-51 years old (n = 108) on a free diet, were divided into a hypercalciuric group (n = 47) with calcium excretion rates higher than 8.0 mmol/24 h, a normocalciuric group (n = 32) with calcium excretion rates below
