Comparative study on different point combinations of Zusanli (ST 36) for improving acute gastric mucosa injury / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To compare effects of different point combinations of Zusanli (ST 36) for improving acute gastric mucosa injury and study on the mechanism.</p><p><b>METHODS</b>One hundred rats were randomly divided into 10 groups, Zusanli (ST 36) group (group A); Zusanli and Neiguan (PC 6) group (group B); Zusanli and Zhongwan (CV 12) group (group C); Zusanli and Gongsun (SP 4) group (group D); Zusanli, Neiguan and Zhongwan group (group E); Zusanli, Neiguan and Gongsun group (group F); Zusanli, Zhongwan and Gongsun group (group G); Zusanli and Neiguan, Zhongwan, Gongsun group (group H); model group (group I); blank control group (group J), 10 rats in each group. Gastric mucosa injury model was made by intragastric infusion of dehydrated alcohol (0. 6 mL/100 g). The gastric mucosa injury index (UI), epidermal growth factor (EGF), nitric oxide (NO) and gastrin (GAS) contents were detected.</p><p><b>RESULTS</b>Contents of EGF and NO were significantly increased and GAS content decreased in all of the EA groups as compared with those in the model group (P<0. 01 or P<0. 05), with no significant differences among group A, B and D, and significant differences as group A compared with group C, F and group H compared with other EA groups.</p><p><b>CONCLUSION</b>Different point combinations of Zusanli (ST 36) can improve acute gastric mucosa injury, with the strongest effect in the Zusanli and Neiguan, Zhongwan, Gongsun group.</p>
