Triple Phosphate

The calculus, which is the subject of the present essay, is the only new species which the author has had an opportunity of observing, in addition to five which he described to the Society in the year 1797. It appears to be comparatively very rare, as he has hitherto seen only two specimens of it; one in the possession of Dr. Reeve of Norwich, and the other in a collection of calculi belonging to Guy’s Hospital. They are in appearance more like the triple phosphate of magnesia than any other calculus, but are more compact and semitransparent, with a slight tinge of yellow.

In 1854 I submitted to the Royal Society a paper “On the frequent occurrence of Indigo in Human Urine.” This communication, which was published in the ‘Philosophical Transactions,’ attracted considerable attention both at home and abroad. The singular fact of the frequent presence of indigo in the urine, first announced by me, has since been amply confirmed by a variety of observers. I have now to place before the Society some investigations in relation to the not uncommon occurrence in human urine of phosphate of lime , as a deposit , in a well-marked crystalline form. When the earthy phosphates are treated of by writers, in connexion with the urine, they are usually described collectively, and it is seldom that each kind of phosphate is particularized, and yet there are several which may occur either separately or together. The phosphate of ammonia and magnesia, or triple phosphate, is indeed often specified, but rarely is phosphate of lime separately mentioned, and phosphate of magnesia scarcely ever; and yet phosphate of lime is very frequently present as a deposit in urine, much more so, indeed, according to my experience, than the triple phosphate, excluding those cases of the occurrence of that ammoniacal phosphate, arising from the decomposition of the urea of the urine subsequent to its escape from the kidneys. Even in those few cases in which phosphate of lime is specially mentioned, it is described usually as mixed up with the other phosphates, and always as occurring in the amorphous or granular , and never in the crystalline state; further, no peculiar importance is attached to it, as contrasted with the magnesian phosphate.

Obstructive urolithiasis is common in confined sheep, and a predominant factor predisposing animals to this condition is nutritional management. The objective of this study was to evaluate the effect of different concentrations of phosphorus (P) on urinalysis, serum urea and creatinine, and serum and urine concentrations of calcium (Ca), P, and magnesium (Mg), as well as to establish the fractional excretion (FE) of these elements in confined lambs. Thirty male Santa Inês x Ile de France sheep at four months of age were divided into two groups according to the diet: Group 1 (G1, n = 15), with 0.43% P in their feed; and Group 2 (G2, n = 15) with 0.65% P. The diets consisting of 10% Coast-cross hay and 90% of a concentrate of soybean meal, wheat, and crushed corn were provided for 90 consecutive days, with water ad libitum. The time points (M) of blood and urine collection were determined as M0, immediately before the beginning of the diet, and at 15-day intervals: M1, M2, M3, M4, M5, and M6. Phosphorous-rich diets favored the appearance of triple phosphate crystals in both groups, causing calculogenesis in more than one third of the animals (11/30), emphasizing the relevance of conducting laboratory tests to aid in urolithiasis diagnosis. In addition, FE revealed an increased renal excretion of excess minerals in the diet, and therefore a greater predisposition for stone formation in relation to nutritional management.

Forty-nine male calves were allotted in a randomized design, initially seven replicates per treatment at the end of the experiment were slaughtered four animals per treatment. Treatments CONT: control diet; FBC120: Dicalcium Phosphate 120:1 ratio P: F; MBC60: Monodicalcium phosphate 60:1 ratio P:F; FBC30: Dicalcium Phosphate 30:1 ratio P:F; SFT30: Super triple phosphate 30:1 ratio P:F; FBC10: Dicalcium Phosphate 10:1 ratio P:F; CAR10: concentrated ratio of 10:1 rock Q:F. Phosphates less elaborate showed higher amounts of heavy metals. In bones, iron, aluminum and lead were higher in FBC10 diet, the copper content was higher in animals fed the diet MBC60. Magnesium in liver was higher in animals fed diet FBC30, aluminum was higher for treatments SFT30 and FBC10, FBC120 and the cadmium and lead levels were higher in animals that received STF30. Treatments did not affect phosphorus and fluorine in muscle and heart, being that chromium was higher in the muscle of animals fed diets CAR10 and STF30 while cadmium in heart was greater in diet CAR10. Kidney phosphorus was higher in the animals fed the diet CAR10 and lower dietary FBC10, while aluminum was higher in the animals fed with the diet FBC10 and lower dietary FBC120 and levels of chromium and lead were higher in animals CAR10 diet and lowest in diet MBC60. Alternative sources of phosphorus and low ratios P:F increased the deposition of minerals in bones and liver, and this mineral deposition was lower in the muscles.
