The uptake of Na^99mTcO₄ (%ID/g) in gastrointestinal organs after stimulating Zusanli (St.36) and Sanyinjiao (SP.6) points showed that the stomach, duodenum, jejunum, ileum, cecum, transverse colon were significant (P < .05) among the groups by one way ANOVA followed by Tukey test. %ID/g: percentage of injected dose per gram of tissue of each organ. (ns) P > .05: not significant; *P < .05: significant; **P < .01: very significant; ***P < .001: extremely significant.
