Hydroxyproline Excretion

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. It is proposed that the rise in the plasma alkaline phosphatase, like that in the hydroxyproline excretion, may reflect the onset of bone loss that occurs after the menopause.

Genetically Determined

A child, studied between the ages of 1½ and 3½ years, presented an abnormally low plasma alkaline phosphatase activity (0.8-1.64 Bessey-Lowry u.), a deformed skeleton and the loss of most of her deciduous teeth. The serum Ca was normal; the serum inorganic phosphate remained at the normal relatively high levels of infancy as the child grew older Roentgenograms demonstrated deficient mineralization of the skeleton and teeth. Biopsies of the liver and the costochondral junction displayed a deficiency of tissue alkaline phosphatase activity. The architecture of the rib was consistent with rickets. There was no evidence for the presence of an inhibitor of alkaline phosphatase, such as beryllium, or for an excessive excretion of the enzyme. Treatment with purified growth hormone, ascorbic acid and thiamin chloride had no effect, while vitamin D 500 thousand u. caused little change in the enzyme activity in a 10 day period. The father had low plasma alkaline phosphatase activity and a number of similar patients are mentioned, for whom there was also evidence that the deficiency in alkaline phosphatase activity may be genetically determined. While the precise role of alkaline phosphatase activity in the metabolism of bone is not clear, the findings in this patient suggest that growing bone may require the presence of alkaline phosphatase for normal calcification, and that the skeletal disorder, which could not be distinguished from rickets, may be related to a disturbance in the local factor.

The effect of starvation and sampling time on plasma alkaline phosphatase activity, total plasma calcium concentration and whole blood ionized calcium concentration was determined in the rat. Starvation caused a significant fall in total and ionized calcium concentrations as well as in alkaline phosphatase activity. These changes were accompanied by a fall in whole blood pH and an increase in the anion gap and a decrease in urinary excretion of calcium. These indices were restored to normal following refeeding. There was no change in serum 25-OH vitamin D concentrations following starvation for 3 days. Alkaline phosphatase activity showed a pattern compatible with the presence of a circadian rhythm when sampling took place between 0800 and 1800 h. Total and ionized calcium concentrations did not show such a rhythm when animals were fed the present diet.

   The menopause correlate with changes in physiological, psychological and biochemical characterized, and also body mass index. The study was analyzed the level of glutamic pyruvic transaminase activity (GPT) , glutamic oxaloacetic transaminase activity (GOT) , alkaline phosphatase activity (ALP) and estimation of body mass index (BMI) in postmenopausal women (n=20) (50-70)years old and premenopausal women (n=20) (30-40) years old. In postmenopausal women the activity of glutamic pyruvic transaminase (GPT) , glutamic oxaloacetic transaminase activity (GOT) , alkaline phosphatase activity (ALP) and body mass index (BMI)  was elevated significantly as compared to premenopausal women (p<0.05) , (P<0.004) , (P<0.002) and (p<0.016) respectably . This study showed with age advances liver become injury and gets abnormal liver functions.
