Abstract
Urinary calculi from three bulls, six bullocks and one male buffalo from the Guntur district were investigated. By chemical analysis only CO23, Ca2+, Mg2+, and a trace of PO¾- were found. X-ray analysis showed that all samples consisted of magnesian calcite with an atomic percentage of magnesium between 14.5 and 21.9. The size of the crystallites varied approx. from 200 to 400 Å.
Keywords: urolithiasis, magnesian calcite, calculi
Sammendrag
Blæresten fra de tre tyre, seks stude og en bøffeltyr fra Guntur distriktet er blevet undersøgt. Ved kemisk analyse fandtes kun carbo nat, calcium, magnesium og et spor af fosfat. Røntgenundersøgelse viste, at alle prøverne bestod af magnesiumholdig calcit med et magnesiumindhold mellem 14,5 og 21,9 atomprocent. Størrelsen af krystalitterne varierede fra ca. 200 til 400 Å.
