城乡中风高危人群血清锌铜铁钙镁的对比分析

COMPARATIVE ANALYSIS OF SERUM Zn,Gu,Fe,Ca AND Mg IN STROKE-PRONE PATIENTS OF URBAN AND RUOAL AREAS

采用原子吸收光谱分析法，对闸北区和南汇县中风高危人群（ＳＰＰ）血清微量元素Ｚｎ，Ｃｕ，Ｆｅ和常量元素Ｃａ，Ｍｇ含量作了抽样调查。结果发现闸北区ＳＰＰ的Ｃｕ，Ｃａ，Ｃａ／Ｍｇ明显低于南汇县ＳＰＰ和对照组，而Ｚｎ，Ｆｅ，Ｍｇ，Ｚｎ／Ｃｕ则高于南汇和对照组。Ｃａ，Ｃａ／Ｍｇ与血压呈负相关，而Ｚｎ／Ｃｕ与血压呈正相关；Ｃａ／Ｍｇ与身体指数和胆固醇呈负相关；Ｚｎ，Ｆｅ，Ｚｎ／Ｃｕ与红细胞压积呈正相关；Ｃａ，Ｃａ／Ｍｇ与低密度脂蛋白呈负相关；Ｚｎ，Ｆｅ，Ｚｎ／Ｃｕ与增龄呈正相关。提示脑中风发病与Ｃｕ．Ｃａ较低而Ｚｎ，Ｐｅ，Ｍｇ较高有密切的关系。

his paper presents the results of a sample survey in Zhabei district and Nanhuicounty. The serum level of Zn, Cu,Fe, Ca and Mg in stroke-prone patients(SPP)weredetermined with GGX-II Atomic Absorption Spcctrophotometer. It was found that thecontents of Cu,Ca,and Ca/Mg of the SPP in Zhabei were significantly lower thanthat in Nanhui and control,while Zn,Mg,and Zn/Cu of the SPP in Zhabei were signi- ficantly higher than that in Nanhui and control.There was a significantly negativecorrelation between Ca,Ca/Mg ang BP,between Ca/Mg and BMI,and Ch,betweenCa,Ca/Mg and LDL-cb, while a significantly positive correlation between Zn/Cu andBP,between Zn,Fe,Zn/Cu and Hct,between Zn,Fe,Zn/Cu and aging,This suggeststhat the incidence of stroke is closely related with the lower contents of Cu,Ca andhigher Zn,Fe,and Mg。
