Abstract:
OBJECTIVE:To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) combined with mosapride on gastric emptying rate and gastric motility in the rats with diabetic gastroparesis.
METHODS:Using random number table method, 68 male SD rats were divided into a blank group (12 rats) and a model establishment group (56 rats). In the model establishment group, the models of diabetic gastroparesis were established with intraperitoneal injection of streptozotocin combined with high-fat and high-sugar diet. Six weeks later, the successful rat models in the model establishment group were randomized into a model group, an EA group, a mosapride group and a combined treatment group, 12 rats in each one. In the EA group, EA was exerted at "Zusanli" (ST 36) (disperse-dense wave, 2 Hz/15 Hz in frequency, 2 mA in intensity) for 20 min. In the mosapride group, mosapride was intervened with intragastric administration (2 mg/kg). In the combined treatment group, electroacupuncture at "Zusanli" (ST 36) was combined with intragastric administration of mosapride. The intervention was given once daily in each group. There was 1 day at interval after 6-day intervention, consecutively for 5 weeks. At the end of intervention, the random blood glucose, gastric emptying rate and the data of gastric motility (average intra-gastric pressure, amplitude and frequency of gastric motility) were detected.
RESULTS:Compared with the blank group, blood glucose was increased in the model group (P<0.001). Blood glucose was reduced in the EA group, the mosapride group and the combined treatment group as compared with the model group separately (P<0.001, P<0.01), whereas, compared with the mosapride group, blood glucose was decreased in the combined treatment group (P<0.05). In comparison with the blank group, the gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were all decreased in the model group (P<0.001) and the frequency of gastric motility was increased (P<0.001). Gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were increased in the EA group, the mosapride group and the combined treatment group (P<0.01, P<0.05, P<0.001) and the frequency of gastric motility was decreased (P<0.001) as compared with the model group respectively. Compared with the EA group, the average intra-gastric pressure and the amplitude of gastric motility were increased in the combined treatment group (P<0.001). In comparison with the mosapride group, the gastric emptying rate, the average intra-gastric pressure, the amplitude and frequency of gastric motility in the combined treatment group, as well as the frequency of gastric motility in the EA group were all increased (P<0.05, P<0.001, P<0.01).
CONCLUSION:Electroacupuncture at "Zusanli" (ST 36) combined with intragastric administration of mosapride could regulate blood glucose and improve the gastric motility in the rats with diabetic gastroparesis. The effect is better than either simple electroacupuncture or mosapride.
