Abstract:
Objective To study the mechanisms of Pericarpium Arecae. Methods A total of Wistar rats were randomly divided into Pericarpium Arecae group and control group, Pericarpium Arecae decoction or distilled water were given respectively. Changes of gastrointestinal motility rats were assayed by Dextran blue-2000 after 1 and 6 hours. The distributions of SP and VIP in antrum and jejunum were investigated by immunohistochemistry assay. Results The gastrointestinal motility of rats was markedly enhanced (P<0.01 or P<0.05). The expressions of SP increased significantly (P<0.01 or P<0.05) and the expressions of VIP decreased significantly (P<0.01 or P<0.05) in antrum and jejunum of rats at 1 and 6 h after Pericarpium Arecae decoction was given. The changes were more obvious at 1 h than at 6 h. Conclusion The kinetogenic effect of Pericarpium Arecae is closely correlated to the increase of SP expression and the decrease of VIP expression in gastrointestinal tract.
