Citric Acid and Bone Metabolism

ثبت نشده
چکیده

From the sedimentation and diffusion constant values obtained in a solution containing 1 g./ 100 ml. H substance, and using the determined value of the partial specific volume, the molecular weight was calculated from the usual equation (Svedberg & Pedersen, 1940) giving a value of 320 000. From the same data the frictional ratio f/fo obtained was 4-2. This corresponds to an axial ratio of > 100, or may be interpreted as indicating a high degree of hydration.

THE EFFECT OF ALUMINUM ON BIOCHEMICAL PARAMETERS RELATED TO BONE METABOLISM. A MODEL STUDY OF HEMODIALYSIS PATIENTS

The influence of aluminum on some serum parameters related to bone metabolism has been investigated by daily administration of aluminum over different periods of time. Daily administration of aluminum (1 mg/kg BW) for 20 or 50 days elevated serum phosphorous concentration by 16 percent and had no significant effect on serum calcium level. When aluminum was injected as a complex with citric...

Citric Acid Metabolism in Carcinogenesis and Its

Previous studies on the calcium metabolism of epidermis undergoing carcinogenesis (@2,10, 11) have suggested the possibility that the action of one or more calcium-binding substances may ac count for the decreased calcium content in hyper plastic epidermis and in a squamous-cell carcinoma. The present investigation has been devoted to a study, in normal and cancerous tissues of the mouse, of th...

Citric acid and calcium metabolism.

Recently there has been increasing realisation of tile important part played by citric acid in the body’s metabolism. Thus administration of pyruvic acid, the intermediate metabolite common to the utilisation of carbohydrate, protein and perhaps fat, causes increased urinary excretion of citrate. Many tissues can form citrate by condensation of pyruvate and oxalacetate followed by reduction, an...

Influence of ingestion of aluminum, citric acid and soil on mineral metabolism of lactating beef cows.

Lactating beef cows (16 Hereford and 34 Angus, 430 kg average body weight, aged 8 to 10 yr) were fed a basal diet containing 200 micrograms/g Al alone or supplemented with Al-citrate, citric acid, soil or soil plus citric acid for 56 d. Diets containing Al-citrate, soil and soil plus citric acid contained 1,730, 1,870 and 1,935 micrograms/g Al, dry-basis, respectively. Adding soil to the diet a...

Aerobic metabolism of glucose by bone.

Osseous tissue is capable of producing net amounts of lactic acid. This has been demonstrated in viva by the measurement of arteriovenous differences (2), in vitro during incubation of slices (3), and in tissue culture (4). Because direct evidence has been lacking, it has been assumed that the Embden-Meyerhof pathway is the route of lactate formation (3). Indeed, various sections of the epiphys...
