Abstract:BACKGROUND: It has been reported diabetic gastroparesis is related to diabetic autonomic neuropathy of the gastrointestinal tract, and berberine (BBR) could ameliorate糖尿病中心和周围神经病。但是,BBR对胃底N的功能和运动的影响Erve不清楚。
方法: 构建了糖尿病大鼠模型,使用染色来观察胃底胃底的形态变化。使用ELISA测量了胆碱能和与氮相关的神经化学指数的变化以及BBR对它们的影响。 The effects of BBR on the neural function and motility of gastric fundus were investigated by electric field stimulation (EFS) induced neurogenic response in vitro.
RESULTS: In the early stage of STZ-induced diabetic rats, the contractile response of gastric fundus induced by EFS was disorder, disturbance of收缩幅度和胃底肌丛中神经元的细胞体呈现了液泡病变。使用BBR给药可以改善上述症状。 BBR进一步增强了在NOS抑制剂或抑制性神经病的情况下的收缩反应劫机者去除。有趣的是,ACH的活性可能不会直接影响释放,并且BBR对收缩反应的增强完全被钙通道阻滞剂完全取消。
结论: 在STZ诱发的糖尿病性疾病的早期,与神经基因的合同无关的疾病, 硝化神经功能障碍。 BBR主要通过影响钙通道来改善胃底神经功能障碍来促进ACH的释放。
