Mineral composition of Uroliths in cattle in the region of Kayseri

Dünya veteriner literatüründe sığır ürolitlerin kantitatif analizi ile ilgili az sayıda rapor vardır. Bu çalışmanın amacı, Türkiye'de sığır böbreklerinde post mortem bulunan ürolitlerinin kantitatif mineral bileşimini rapor etmekti. Bu çalışmada, 1.840 tane sığır (1.060 erkek ve 780 dişi) incelendi. Ürolit 1.840 hayvanın 20 tanesinde bulundu. Bu ürolitlerin 12 (% 60)’si erkek, 8 (% 40)’i dişilerden elde edildi. Ürolit prevalansı %1.08 olarak belirlendi. Ürolit örnekleri ışık mikroskobu ve kızılötesi infrared spektroskopi ile analiz edildi. Tespit edilen 20 ürolitlerin analizleri ile ilişkili olarak, 11 (%55)’i magnezyum kalsiyum fosfat karbonattan, 2 (% 10)’si magnezyum kalsiyum fosfat 2 (% 10)’si slika, 1 (% 5)’i magnezyum amonyum fosfat heksahidrat (struvit), 1 (% 5)’i kalsiyum karbonat, 1 (% 5)’i kalsiyum fosfattan oluştuğu belirlendi. Bir ürolitin bileşimi silika kabuk ile çevrili kalsiyum karbonat merkezli bir bölümden oluştu. Diğer ürolitin bileşimi % 90 kalsiyum fosfat karbonat ve % 10 struvit merkezli ve % 85 magnezyum kalsiyum fosfat karbonat ve % 15 struvit bir kabuk sarılıydı.

Kayseri Bölgesi sığırlarında ürolitlerin mineral kompozisyonu

There are a few reports on quantitative analysis of bovine uroliths in the world's veterinary literature. The aim of the present study was to report the quantitative mineral composition of uroliths found at post mortem in kidneys of cattle in Turkey. In this study, 1840 cattle were examined (1060 male and 780 female). Uroliths were found in 20 of 1.840 animals. These uroliths were obtained from 12 (60%) males and 8 (40%) females. The prevalence was 1.08%. Urolith samples were analyzed by polarizing light microscopy and infrared spectroscopy. Analyses of the 20 uroliths revealed that 11(55%) were composed of magnesium calcium phosphate carbonate, 2 (10%) were magnesium calcium phosphate, 2 (10%) were silica, 1 (5%) was magnesium ammonium phosphate hexahydrate (struvite), 1(5%) was calcium carbonate, 1 (5%) was calcium phosphate compound. One compound urolith was composed of a central portion of calcium carbonate surrounded by a shell of silica. The other compound urolith was composed of a center of 90% calcium phosphate carbonate and 10% struvite, surrounded by a shell of 85% magnesium calcium phosphate carbonate and 15% struvite.
