Male Wistar rats (<jats:italic>n<\/jats:italic> = 21) were allocated into three groups of seven each. Group 1 was treated by acupuncture bilaterally at St.36; Group 2 at SP.6; and Group 3 was untreated (control). After 10 min of needle insertion in anesthetized rats, 0.3 mL of Na<jats:sup>99m<\/jats:sup>TcO<jats:sub>4<\/jats:sub> (7.4 MBq) was injected via ocular\u2010plexus. After 20 min, the exitus of animals was induced by cervical\u2010dislocation and GIT organs isolated. However, immediately before the exitus procedure, blood was collected by cardiac\u2010puncture for blood radio\u2010labeling (BRL). The radioactivity uptake of the blood constituents was calculated together with the GIT organs by a well gamma counter. The percentage of injected dose per gram of tissue (%ID\/g) of Na<jats:sup>99m<\/jats:sup>TcO<jats:sub>4<\/jats:sub> was calculated for each GIT organs, while BRL was calculated in %ID. According to the one\u2010way ANOVA, the stomach, jejunum, ileum from the treated groups (Group 1 and Group 2) had significant differences compared to the controls (Group 3). However, between the treated groups (Group 1 and Group 2), there were significant differences (<jats:italic>P<\/jats:italic> &lt; .05) in the stomach, jejunum, ileum, cecum, transverse and rectum. In BRL analysis, Group 2 showed significant increase and decrease of the insoluble and soluble fractions of the blood cells, respectively (<jats:italic>P<\/jats:italic> &lt; .0001). The authors suggest that St.36 may have a tendency of up\u2010regulation effect on GIT, whereas SP.6, down\u2010regulation effect. However, further rigorous experimental studies to examine the effectiveness of acupuncture in either acupuncture points need to be carried out.<\/jats:p>","DOI":"10.1093\/ecam\/nep009","type":"journal-article","created":{"date-parts":[[2009,2,13]],"date-time":"2009-02-13T01:54:51Z","timestamp":1234490091000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Acupuncture at \u201cZusanli\" (St.36) and \u201cSanyinjiao\" (SP.6) Points on the Gastrointestinal Tract: A Study of the Bioavailability of \u2009<sup>99m<\/sup>Tc\u2010Sodium Pertechnetate in Rats"],"prefix":"10.1155","volume":"2011","author":[{"given":"Vasco","family":"Senna-Fernandes","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisy L.
