迷走神经兴奋,通过其胆碱能纤维和蛙皮素肽能纤维促进胃泌素释放。为研究应激反应时胃泌素的释放机理,本工作以束缚_-寒冷刺激为应激模型,测定了对照组、假手术组、阿托品组和迷走神经切断组大鼠应激前、后血清胃泌素的含量。 材料和方法实验采用杂种雄性大鼠26只,体歪 200～250g,随机分成对照、假手术、皮下注射阿托品(5mg/kg,应激前30min)和膈下迷走神经切断4组。实验前24h禁食,可自由饮水。在乙醚麻醉下,常规消
The vagus nerve is excited to promote gastrin release via its cholinergic fibers and bombesin peptide-energy fibers. In order to study the mechanism of gastrin release during stress response, this work used a tying-chilly stimuli as a stress model to determine the pre- and post-stress of serum in control, sham-operated, atropine, and vagotomy rats. The content of the hormone. Materials and Methods Experiments Twenty-six male hybrid rats, 200-250 g body tine, were randomly divided into control, sham operation, subcutaneous atropine (5 mg/kg, 30 min before stress) and subdiaphragmatic vagotomy. 24-hour fasting before the experiment, free access to water. Under ether anesthesia, conventional elimination
