许多资料证明,针刺具有复杂的调整作用。对于针刺作用的机制,很多研究者曾分别用各种生物化学的手段,如荧光分析、凝胶渗透层析、放射免疫等方法做了大量的实验研究工作,对生物体内存在的单胺类、脑内活性多肽、环核苷酸及一些酶类在针刺中的作用颇感兴趣。本文就这些生物活性物质在针刺进程中的变化和作用作一系统的评价和介绍,以探讨针刺镇痛的生化机理。 Many sources show that acupuncture has a complex adjustment effect. For the mechanism of acupuncture, many researchers have done a large number of experimental studies using various biochemical methods such as fluorescence analysis, gel permeation chromatography, and radioimmunoassay. The role of active peptides, cyclic nucleotides, and some enzymes in the brain is of interest in acupuncture. In this paper, a systematic evaluation and introduction of the changes and effects of these bioactive substances in the acupuncture process were conducted to explore the biochemical mechanism of acupuncture analgesia.
