Energy dispersive spectrophotometry based quantitative elemental estimation of equine enterolith

A male horse of six years old showing episodic, mild to moderate abdominal pain with congested mucous membranes and mild dehydration. Rectal temperature, heart and respiratory rates were recorded 100.7°F, 56 per min and 20 per min, respectively. Per-rectal examination revealed mucoid scanty faeces and hard mass of stone in the rectum and the case was diagnosed as of enterolithiasis. The enteroliths recovered were assessed morphologically and analysed using Energy Dispersive X-rays Spectrophotometer (EDS) for elemental analysis. The predominant elements present on the surface of the enterolith were O (72.43%), P (9.10%), Mg (10.79%), Si (2.59%), Al (1.63%) and Na (1.49%). The mid layer was predominated by O (67.04%), P (8.31%), Mg (6.87%) and N (9.91%) and in core, O (73.13%), P (9.66%), Mg (8.24%) and N (7.89%).
