First, we examined the mast cell density at PC 6, adjacent acupoint LU 7, and a non-acupoint. We tested the effects of EA at PC 6 on heart rate (HR) and blood pressure (BP) in rabbits with pituitrin-induced bradycardia. We also injected sodium cromolyn (Cro), a mast cell membrane stabilizer, at PC 6 30\u2009min before EA to investigate if it affected the EA effects. The results showed that in both PC 6 and LU 7, the mast cell densities were higher than in the non-acupoint (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). EA could induce mast cell degranulation at PC 6, which could be suppressed by sodium cromolyn (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). EA improved HR, though the change was relatively small in the initial stage with a significant change at 35\u2009min after modelling (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). BP significantly improved at 10\u2009min after the onset of pituitrin-induced bradycardia (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). The EA effects on both HR and BP were suppressed by sodium cromolyn (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). Therefore, we concluded that mast cells in the acupoint are important for the EA effects against pituitrin-induced bradycardia in rabbits.<\/jats:p>","DOI":"10.1038\/s41598-017-08855-5","type":"journal-article","created":{"date-parts":[[2017,8,16]],"date-time":"2017-08-16T10:04:33Z","timestamp":1502877873000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Mast cell activation in the acupoint is important for the electroacupuncture effect against pituitrin-induced bradycardia in rabbits"],"prefix":"10.1038","volume":"7","author":[{"given":"Haining","family":"Zhu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuezhi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Jing","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guanghong","family":"Ding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2017,8,22]]},"reference":[{"key":"8855_CR1","unstructured":"Zhang, D., Ding, G., Shen, X., Yao, W. & Lin, J.
