本文以胃窦位相性收缩为指标探讨促神经素(NSP)对植物神经中枢的作用。实验在肌松成年猫上进行。结果表明:15例动物中10例在尾端延髓背部注射10μl NSP后,胃窦位相性收缩幅度明显增强,收缩频率稍有减慢,其效应以注射后10min和30min时为最强。以生理盐水为对照,15例中仅有5例收缩幅度明显增强,且其效应以注射后即刻为最强,作者认为这可能是机械刺激所造成。文中对NSP增强胃运动的作用途径进行了讨论。 In this paper, the phase of gastric contractility as an indicator of pro-neurostimulator (NSP) on the autonomic nervous center. The experiment was performed on a muscle pine adult cat. The results showed that in 10 animals, 10 cases of NSP injected into the dorsal medulla oblongata caused a significant increase in the phase contractility of gastric antrum and a slight decrease in the frequency of contractions. The effect was strongest at 10 min and 30 min after injection. With saline as control, only 5 of 15 patients showed a significant increase in the contractile amplitude, and their effect was most pronounced immediately after injection, which the author believes may be caused by mechanical stimulation. In this paper, the role of NSP in enhancing gastric motility is discussed.
