以往的研究资料表明,分别损毁中缝核和蓝斑核以及从蓝斑核发出的上行背束时,前者减弱针刺镇痛效应,后者加强这种效应;若刺激中缝核和蓝斑核,它们对针刺镇痛效应分别表现为易化和压抑的作用,这些结果从正反两方面提示了中缝核和蓝斑核在针刺镇痛中的作用是拮抗性的。从针刺对蓝斑核和背中缝核细胞放电的同时性影响中,看到针刺对蓝斑细胞放电多为兴奋性的,而吗啡均呈抑制性影响,结合蓝斑有纤维向背中缝核投射的结果,可以设想,蓝斑的机能活动状
Previous studies have shown that the former attenuates acupuncture analgesia and the latter strengthens this effect when the SCG and the locus coeruleus, respectively, and the posterior dorsal beam emitted from the locus coeruleus are damaged, respectively. If the nucleus and locus coeruleus are stimulated, Their effects on acupuncture analgesia were facilitated and repressed, respectively. These results suggest both the anther and the locus coeruleus in acupuncture analgesia to be antagonistic, both positive and negative. From the acupuncture on the locus coeruleus nucleus and dorsal raphe cells discharge simultaneously, we see acupuncture on the discharge of the macula more excitable, and morphine were inhibited, combined with the blue spot to the dorsal raphe As a result of nuclear projection, it is conceivable that the activity of locus coeruleus is characteristic
