| 摘 要： | ３９例血清样品用酸消化和酸稀释制备待测液，ＩＣＰ－ＡＥＳ相同条件下同时测定Ｆｅ、Ｚｎ、Ｃｕ、Ｃｒ、Ｃｄ和Ｐｂ。统计结果表明，消化法测得Ｆｅ、Ｚｎ和Ｃｒ显著高于稀释法，Ｃｄ低于稀释法；Ｃｕ和Ｐｂ两法测得结果无显著差异。相关分析表明，两法测得Ｆｅ、Ｃｕ、Ｚｎ和Ｃｒ正相关；Ｐｂ和Ｃｄ不相关。ＩＣＰ－ＡＥＳ测定动脉粥样硬化和健康对照组间人血清六种微量元素稀释法无显著差异，而消化法测得组间不同程度存在显著性差异。建议采用消化法制备待测液较好。 |

| Abstract: | Fe,Zn,Cu,Cr,Cd and Pb concentrations in serum of 21 arteriosclerosis(AS) and 18 healthy control(CK) were determined by ICP AES,and sample solution was prepared using acid digestion(Dig.) and acid dilution(Dil.) procedure.Serum total Fe,Zn and Cr were significantly higher using Dig.than that using Dil.Serum Cu and Pb were of no significant differences using the both procedures.Serum Cd was significantly lower using Dig.than that using Dil.The results of Fe,Cu,Zn and Cr were positively correlated between Dig.and Dil.,but those of Pb and Cd were of no significant correlation.Six elements concentrations in serum determined were significantly different between AS and CK using Dig.The digestion procedure was recommended for serum trace elements analysis using ICP AES. |
