چکیده

Problem statement: In our earlier study, dietary pectin has been shown to promote nephrocalcinosis in rats when compared with the feeding of cellulose. It was not known whether this pectin effect relates to its structure or to its monosaccharide component, galacturonic acid. Approach: The effects of dietary pectin, galacturonic acid and glucose on kidney calcification were studied in female rats. The purified diets used had similar concentrations of calcium, magnesium and phosphorus. Results: It was confirmed that the feeding of pectin (10%, w/w) versus cellulose in diets containing 0.4% phosphorus results in significantly greater calcium and phosphorus concentrations in kidney. The new finding was that pectin had a nephrocalcinogenic effect when compared with either galacturonic acid or glucose. Conclusion: The stimulatory effect of pectin on the development of nephrocalcinosis is specific and is related to its structure rather than to its galacturonic acid component.

Nephrocalcinosis in Female Rats Fed Diets Containing Either Pectin or Cellulose

Problem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced for...

Inhibitory effect of high protein intake on nephrocalcinogenesis in female rats.

Increased intakes of protein have been shown to reduce kidney calcification (nephrocalcinosis) in female rats. Two questions were addressed in the present study. First, can protein-induced inhibition of nephrocalcinosis be demonstrated when the diets used are balanced for calcium, magnesium and phosphorus in the added protein? Second, can the protein effect be explained by the frequently observ...

Phosphate and the development of nephrocalcinosis in rats fed diets containing alpha protein.

It has been suggested that nephrocalcinosis in rats fed diets containing alkali-treated soy protein may be due to a high availability of phosphate in the diet. In the present study, the development of nephrocalcinosis in rats fed a diet containing 20% alpha protein (an alkali-treated soy protein) was compared with that in rats fed the same diet supplemented with additional phosphate. Phosphate ...

Dietary protein, fat, and minerals in nephrocalcinosis in female rats.

Young female rats fed semipurified diets containing casein or a soy protein isolate had extensive nephrocalcinosis at the junction between the outer and inner stripe of the outer medullary zone after 5 wk on the diets, whereas rats fed a diet containing a lactalbumin concentrate did not. Although the percentages of actual protein and of total ash were similar in all three diets, the concentrati...

Nephrocalcinosis and diets containing alkali- and non-alkali-treated soy protein.

Diets containing alkali-treated soy protein have been shown to cause nephrocalcinosis in rats. In order to determine if alkali-treated soy protein is the dietary component that induces nephrocalcinosis, the effects of a purified diet containing 20% alpha-protein (an alkali-treated soy protein) were compared with the effects of the same diet containing 20% promine-D (a non-alkali-treated soy pro...
