... to their menopausal status. However, postmenopausal thyroidectomized patients showed significantly lower bone mass ( P < 0.001) than premenopausal patients. 3. L-Thyroxine-treated patients showed significantly higher levels of bone alkaline phosphatase and urine hydroxyproline excretion than control subjects ( P...

...R. G. Crilly; M. M. Jones; A. Horsman; B. E. C. Nordin 1. Plasma alkaline phosphatase activity and urine hydroxyproline excretion were measured in age-matched premenopausal and postmenopausal women. 2. Both measurements were found to be significantly higher in postmenopausal women. 3...

...A. M. Asatoor; M. R. Bending; M. D. Milne 1. The plasma concentrations and urinary output of proline and hydroxyproline contained in peptides were measured in normal rats and in rats with Fanconi syndrome produced by injection of sodium maleate. All animals received a prior injection of 10 mg...

... necrosis, and consequently there is a delay of some months between the causal incident and the first diagnosis by radiography. 3. As a possible method for the earlier detection of bone necrosis the 24 h urinary excretion of hydroxyproline was measured over a period before and after experimental production...

...C. J. Bates 1. Plasma and buffy-coat vitamin C, urinary proline, hydroxyproline, creatinine and total amino acid concentrations were measured in 23 healthy elderly subjects at intervals of 3 months. 2. There was a strong positive correlation between plasma vitamin C and buffy-coat vitamin C. 3...

... and the excess was shown to be highly significant statistically. 2. A considerable fraction of the excess of peptide output was shown to consist of hydroxyproline-containing peptides derived from collagen degradation. 3. The method of rank correlation showed that the difference both in free amino acid...
