摘要
Objective: To investigate the influence of acupuncture at the points of Foot-Yangming Meridian on intracellular concentration of Ca2, called the 2nd messenger of gastric smooth muscles. Methods: 45 rabbits were randomly divided into the following 5 groups: a normal saline group, a model group treated with atropine, an acupuncture group treated by needling the points of Foot-Yangming Meridian, an acupuncture group treated by needling the points of Foot-Shaoyang Meridian, an acupuncture group treated by needling the points of Foot-Taiyang Meridian, i.e. 9 rabbits in each group. After treatment, the smooth muscles of the gastric antrum were taken to make the suspension containing alive single muscular cells, and the intracellular calcium concentration ([Ca2+]i) was determined by a spectrofluorometer. Results: The concentration of [Ca2+]i in the group of Foot-Yangming Meridian was obviously higher than that of the atropine group (P<0.01), but with no significant differences found among all the other groups (P>0.05). Conclusion: The influence of acupuncture at the points of Foot-Yangming Meridian on gastric movement is related to the release of intracellular Ca2+ in the gastric smooth muscles.
Objective： To investigate the influence of acupuncture at the points of Foot-Yangming Meridian on intracellular concentration of Ca^2, called the 2nd messenger of gastric smooth muscles. Methods： 45 rabbits were randomly divided into the following 5 groups： a normal saline group, a model group treated with atropine, an acupuncture group treated by needling the points of Foot-Yangming Meridian, an acupuncture group treated by needling the points of Foot-Shaoyang Meridian, an acupuncture group treated by needling the points of Foot-Taiyang Meridian, i.e. 9 rabbits in each group. After treatment, the smooth muscles of the gastric antrum were taken to make the suspension containing alive single muscular cells, and the intracellular calcium concentration （[Ca^2＋]i） was determined by a spectrofluorometer. Results： The concentration of [Ca^2＋]i in the group of Foot-Yangming Meridian was obviously higher than that of the atropine group （P〈0.01）, but with no significant differences found among all the other groups （P〉0.05）. Conclusion： The influence of acupuncture at the points of Foot-Yangming Meridian on gastric movement is related to the release of intracellnlar Ca^2＋ in the gastric smooth muscles
