以等离子发射光谱仪测血清Fe、Mo、Ni、Pb、Si、Sn、Sr、V、Ca、Mg、Cd、Co、Cr、Cu、Mn、Zn,以F-78型脉冲极谱仪测Se,观察我国四个地区、六个人群(三个民族)共325名男性(40～59岁)的元素—血压(BP)关系,发现元素水平有地区、民族差别;血清Pb、Ni、Si、Sn、V、Cd、Cr间相关系数大,而Sr则具相对独立性;从多因子逐步回归和判别分析,Sr无论在正常血压、高血压和总合并组,恒定与血压正性联系;在部分组Ca(Ca/Mg)、Fe、Co与血压正性联系,血Cr、Sn与血压负性联系;有害元素Cd在血压水平较高的人群水平反低,与血压反而呈负性联系,可能系元素在体内组织和血中分布不一致的缘故。研究并提示,在高血压组必需元素Ni、V、Co、Cr水平较低;血Ca与尿Ca水平不并行,前者不能完全反映Ca摄入量。
The contents of Fe, Mo, Ni, Pb, Si, Sn, Sr, V, Ca, Mg, Cd, Co, Cr, Cu, Mn and Zn were measured by plasma emission spectrometer. Elemental-blood pressure (BP) relationships among 325 males (aged 40-59 years) in four regions and six populations (three ethnic groups) in our country were observed. There were regional and ethnic differences in the elemental levels; serum Pb, Ni, Si, Sn , V, Cd, Cr between the correlation coefficient is large, while Sr is relatively independent; stepwise regression and discriminant analysis by multiple factors, Sr no matter in the normal blood pressure, hypertension and the total combined group, constant positive and blood pressure; Group Ca (Ca / Mg), Fe, Co and blood pressure were positive, blood Cr, Sn and blood pressure negative correlation; harmful elements Cd in people with high blood pressure levels were anti-low, but negatively correlated with blood pressure may Department of elements in the body tissue and blood distribution inconsistencies. Studies and tips, essential elements in the hypertension group Ni, V, Co, Cr levels are low; blood Ca and urinary Ca levels are not parallel, the former can not fully reflect the Ca intake.
