免疫学杂志990420摘 要 为了探索内源性钠泵抑制因子在高血压发生中的作用,利用家兔免疫制备了抗哇巴因抗体及抗前海葱苷原A抗体,并对其特性进行了鉴定。利用该两种抗体和ELISA法检测了高血压病人血浆及牛血清中哇巴因样及前海葱苷原A样钠泵抑制因子水平。检测结果发现原发性高血压病人血浆中存在哇巴因样物质水平(0.132±0.021mol/L)和前海葱苷原A样物质水平(0.102±DF8.8nmol/L);牛血清中哇巴因样物质的水平(1.6±0.27nmol/L)明显高于前海葱苷原A样物质水平(0.222±0.086nmol/L)。证明内源性钠泵抑制因子哇巴因样及前海葱苷原A样物质在哺乳类动物血液里循环存在,是两种新的强心苷类固醇激素。., http://www.100md.com

Abstract To know the concentration of the isomer of ouabain substance and proscillaridin A-like substance how correlate with hypertension, we raised antibodies against ouabain and proscillaridin A and tested its concentration in the plasma of patients with essential hypertension and bovine serum with an indirect enzyme-linked immunosorbent assay. The results show that in human plasma exist ouabain-like substance (0.132±0.021nmol/L)and proscillaridin A-like substance (0.102±DF8.8nmol/L),and that in bovine serum the higher concentration of ouabain immunoreactivities (1.6±0.27nmol/L) than proscillaridin A immunoreactivities (0.222±0.086nmol/L). We concluded that both concentration of the ouabain immunoreactive and proscillaridin A immunoreactive materials circulating in blood correlates with the blood pressure in essential hypertension.

80年代初国外学者报道在哺乳类动物体内存在一种内源性类洋地黄物质(Endogenous digitalis-like factor, EDLF),与地高辛抗体呈免疫反应,具有抑制细胞膜Na+ -K+ -ATP酶(钠泵)活性的作用,故称其为“钠泵抑制因子”,与血压和心功能调节有关。90年代初Hamlyn及其同事证明高血压病人血浆中的EDLF是一种哇巴因样物质[1],Haupert等证明牛下丘脑EDLF为哇巴因同分异构体[2]。另有学者从心衰病人血浆中提取纯化得到海蟾蜍毒素(Marinobufagenin)[3],从高血压病人血浆中检测到前海葱苷原A样物质(Proscillaridin A-like subs-tance),与血压升高相关[4]。为了进一步探索这两类物质是否同时在哺乳类动物体内存在,本文利用家兔免疫制备了抗哇巴因抗体及抗前海葱苷原A抗体,并对其进行了鉴定,用ELISA法利用该两种抗体检测了高血压病人血浆和牛血清中哇巴因样及前海葱苷原A样物质水平,现将结果报告如下。do44/y4, 百拇医药

我们以往的研究证实,在高血压病人血浆中存在一种具有强力抑制Na+ -K+ -ATP酶活性的哇巴因样内源性钠泵抑制因子,其水平高于正常人[5];也证实在哺乳类动物体内同时存在哇巴因样和前海葱苷原A样两种钠泵抑制因子,尤以肾上腺和下丘脑最为丰富[6]。本研究证据表明,在高血压病人血浆和牛血清中同时存在两种钠泵抑制因子哇巴因样和前海葱苷原A样物质,前者浓度高于后者。该免疫制备物抗哇巴因抗体与哇巴因发生免疫反应,而与前海葱苷原A不发生免疫反应;抗前海葱苷原A抗体与前海葱苷原A发生免疫反应,而与哇巴因几乎不发生交叉反应,表明该两种内源性钠泵抑制因子在哺乳类动物体内同时独立存在,并可能与高血压的发生和发展有关。这两种抑制因子的生物合成部位和化学特性,以及在高血压发病中的病理生理作用机制还在进一步研究中。(w8jki, 百拇医药
