采用电解损毁核团及脑区微量注射方法，探讨孤束核在下丘脑前部减压区注射神经降压素对静脉注射新福林兴奋压力感受性反射中的作用。结果表明，①电解损毁弧束核后，新福林升压效应显著升高（Ｐ＜０．０１）；②电解损毁孤束核后，下丘脑前部减压区注射神经降压素，新福林升压效应无显著改变（Ｐ＞０．０５）。提示神经降压素在下丘脑前部减压区易化压力感受性反射作用可能主要通过孤束核而实现的。 To investigate the effect of injecting neurotensin in the hypothalamic anterior hypothalamic nucleus on the excitatory baroreflex in the intravenous injection of nebuline by electrolyzed damaged nuclei and brain microinjection. The results showed that (1) the voltage boosting effect of neopagantin was significantly increased (P <0.01) after electrolytic destruction of the nucleus of arcuate nucleus; (2) EEG was injected into the anterior hypothalamic decompression zone after electrolytic destruction of the nucleus tractus solitarius There was no significant change in the booster effect (P> 0.05). Prompt neurotensin in the hypothalamic anterior decompression zone susceptibility to baroreflex may be mainly through the solitary tract.
