Eye fluids (aqueous humour and vitreous humour) may be helpful in estimating ante-mortem blood levels, since some parameters measured in these fluids have proved to be stable or to change in a predictable way after death. This would help in diagnosing the cause of death in some diseases or to evaluate ante-mortem blood levels in certain animals not easy to handle or with difficult access. In order to establish reference values of some parameters in blood and eye fluids (aqueous humour and vitreous humour), as well as the possible correlation among these three different fluids, various minerals and electrolytes (Ca, P, Mg, K, Na, Fe, Cr, Co, Ni, Cu, Zn, Se and Mo) were measured in 15 four to five year-old Lidia bulls, all dying after a period of significant stress and major exertion. Plasmatic values of Mg and P were much greater than reported in the literature. In general, mineral plasmatic values were greater than those found in ocular fluids (aqueous and vitreous), while Na, K and Cr were similar in the three fluids. We have verified the existence of correlations in P, Co and Mo among the three fluids measured, and between Se of plasma and vitreous humour. But the most marked correlations were observed in Mo (plasma -aqueous humour, r = 0.893, plasma-vitreous humour, r = 0.945, HA -HV, r = 0.849), in P (plasma-vitreous humour, r = 0.726) and in Co (plasma-vitreous humour, r = 879).
眼内液体（房水和玻璃体）可能有助于估计生前血液水平，因为在这些液体中测量的一些参数已被证明是稳定的，或者在死后会以可预测的方式变化。这将有助于诊断某些疾病的死因，或评估某些不易处理或难以采血的动物的生前血液水平。为了确定血液和眼内液体（房水和玻璃体）中某些参数的参考值，以及这三种不同液体之间可能的相关性，我们对15头4至5岁的利迪亚公牛进行了各种矿物质和电解质（钙、磷、镁、钾、钠、铁、铬、钴、镍、铜、锌、硒和钼）的测量，这些公牛在经历一段显著压力和剧烈运动后全部死亡。血浆中镁和磷的值远高于文献报道。一般来说，血浆中的矿物质值高于眼内液体（房水和玻璃体）中的值，而钠、钾和铬在三种液体中的含量相似。我们已经证实了所测的三种液体中的磷、钴和钼之间，以及血浆和玻璃体中的硒之间存在相关性。但最显著的相关性出现在钼（血浆-房水，r = 0.893；血浆-玻璃体，r = 0.945；房水-玻璃体，r = 0.849）、磷（血浆-玻璃体，r = 0.726）和钴（血浆-玻璃体，r = 0.879）上。
