... associated with various metabolic myopathies, including osteomalacia. 2. The maximum voluntary contraction (MVC) of the dominant quadriceps and plasma 25-hydroxycholecalciferol [25-(OH)D] were measured in male alcoholics and control subjects to determine whether vitamin D deficiency contributed to proximal...

..., height, weight and sex in a multi-factorial analysis. 4. Only in males did MVC correlate with height and weight. Asian women were more obese than any other group, and showed an increase in body mass index with age. 5. Twenty-two per cent of Asian subjects had marked vitamin D deficiency (plasma 25...

The response to exogenous parathyroid hormone (PTH) was tested in normal subjects and patients with osteomalacia due to vitamin D deficiency; 200 MRC units of bovine PTH were administered intravenously. 2. The rise...

... pmol/l. Seven Asian patients with osteomalacia due to vitamin D deficiency had very low or undetectable (< 96–231 pmol/l) circulating 25,26-dihydroxycholecalciferol concentrations. 3. The metabolite was detectable in the sera from seven anephric patients (mean 262 ± 43 pmol/l), indicating...

.... Formation of radioactive 1,25-(OH) 2 D 3 was detectable only in vitamin D—deficient subjects. Between individuals, its maximum serum concentration was correlated significantly and inversely with serum calcium but with no other measured variable. In the individual, concentrations of radioactive serum 1,25...

Mean amounts of peak II were higher in patients with chronic renal insufficiency than in nutritional vitamin D deficiency, in pseudohypoparathyroidism and in primary hyperparathyroidism, despite comparable amounts of PTH-(1–84). 3. In chronic...

In control subjects with relative vitamin D deficiency [serum 25-(OH)D 3 <2.5 nmol/l (10 ng/ml)], serum labelled 1,25-(OH) 2 D 3 was related inversely to the serum 25-(OH)D 3 and serum calcium, and directly to serum immunoreactive...
