Abstract:
The aim of the present study was to measure changes in the serum concentrations of some elements in endotoxin-challenged calves using a particle-induced X-ray emission analysis and to screen for elements useful as diagnostic markers. The results obtained revealed that serum Zn concentrations were more accurate diagnostic markers for detecting endotoxin shock in calves than other elements. Serum Zn level in endotoxin-challenged calve was significantly lower from 8 to 12 hr after the endotoxin challenge than pre-challenge values. In addition, serum Zn concentrations in calves from 4 to 24 hr after endotoxin challenges were significantly lower than those of control. Our results indicate that serum Zn concentration has potential as diagnostic markers for detecting inflammation in calves with endotoxin shock.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
