放射免疫测定法是六十年代初开始发展起来的一项新的超微量分析技术

它是利用免疫学上抗体和抗元之间相互反应的高度特异性和放射性同位素检测技术高度的灵敏性相结合而形成的一门新兴学科。放射受体分析的原理与放射免疫分析相似

只不过是用组织受体代替抗体

作为结合试剂而已

实际上它也是竞争性蛋白结合分析法的一种

所不同的是它以受体蛋白作为特异性结合剂。目前

常将放射免疫法、竞争性蛋白结At present

radioimmunoassay

competitive protein binding assay and ra- dioreceptor assay in all known as "compotitive radioassay" or "saturation a- ssay". The technique has the advantages of high specificity

senstivity

a- ccuracy andsimplicity. In this paper author review the recent main applications of the compe- titive radioassay in studies on the role of endogenous morphine-like su- bstances in acupuncture analgesia and the effects of acupunctre on adre- nal cortical hormones

female hormones

cyclic nucleotides and other ho- rmones. A great amount of important information for explaining acupuncture mechanism were accumulated The technique would be more widelier applied in the studies on acupu-ncture biochemical mechanism with its development.
