The pathogenesis of equine grass sickness (EGS) has not fully understood. A better understanding of the exact pathogenesis of diseases can help to make an accurate diagnosis. Previous studies reported some pathological damage of neuronal cells in EGS patients. In this study, primarily cytotoxicity of serum from three clinically EGS-diagnosed horses on PC12 Tet-off (PTO) cells was assessed. Subs...

Uncharged reductants, such as NNN'N'-tetramethyl-p-phenylenediamine and diaminodurene, reduce cytochrome c at both high and low ionic strength, unlike ascorbate, which is effective only at low ionic strength. The 'tightly bound' cytochrome c-cytochrome c oxidase complex, with 1 equiv. of cytochrome c per cytochrome aa3, can be prepared by simple mixing of the two component species. Its properti...
