外周有关递质对疑核（AMB）调节细胞免疫机能的影响

The Effect of Peripheral Neurotransmitter on Nucleus Ambiguus ( AMB ) Regulating Cellular Immunity in Rabbits

疑核是重要的内脏运动核和躯体运动核，它与中枢神经系统和外周器官建立了广泛的神经联系。

Nucleus ambiguus ( NA ) is an important visceral and somatic motor nucleus which establishes widely connections with the central nervous system and peripheral organs .

Colocalization of somatostatin ( SOM ) and nitric oxide synthase ( NOS ) in the pharyngeal motor neurons of the nucleus ambiguus of the rat was investigated using the pseudorabies virus ( PRV ), SOM and NOS triple labeling method .

这表明家兔起自疑核和舌下神经核的环甲肌运动神经元有些是胆碱能神经元，起自疑核的神经元有的是ENK样反应阳性神经元。

It suggests that in the rabbit some of the CTm motoneurons arising from the ambiguous and hypoglossal nuclei should be cholinergic , some from the ambiguous nucleus should be ENK-like immunoreaction positive neurons .

本工作观察了微电泳给予OMF对大鼠延髓疑核呼吸相关单位自发放电活动的影响。

In the present study , it was observed that ohmefentanyl ( OMF ) affected mi-croiontophoretically applied spontaneous discharges of respiration related units ( RRUs ) in the nucleus ambiguus of rats .

分别在静注阿托品、酚妥拉明或心得安后电刺激疑核，并分别于注射前及刺激后不同时间取外周血，测定T细胞百分率及对PHA的反应。

The AMB of animals were stimulated after Atropine or Phentolamine or Propranolol were injected from venous , and peripheral blood samples were taken before injection and 10,30,60,120 and 180 min after stimulation respectively to determine percentage of T cell and mito-genic response to phytohemagglutinin ( PHA ) .

生长抑素调节疑核神经元兴奋性氨基酸受体介导的兴奋

Somatostatin regulates excitatory amino acid receptormediated activity on neurons in the nucleus ambiguus

支配咽肌的运动神经元位于疑核，控制凝核的前运动神经元位于孤束核。

The motor neurons of pharyngeal musculature are located in the nucleus ambiguus .

迷走神经运动背核和疑核特别发达；

The dorsal motor nucleus of the vagus nerve and nucleus ambiguus are well developed ;

由此认为，疑核与甲状腺之间存在机能联系，刺激疑核可引起甲状腺功能抑制，并且这种联系可能是由起源于疑核，支配甲状腺的副交感神经所介导的。

This depression is mediated by parasympathetic nerve which originates from NA and innervates the thyroid .

迷走复合体和疑核是调控胃机能的初级中枢。

Thus , the DVC and NA are the primary nerve centres of regulating gastric functions .

疑核内含有大量的神经递质，如乙酰胆碱，生物胺，神经肽，氨基酸等及其受体。

NA contains a great variety of neurotransmitters including acetylcholine , biogenic amines , neuropeptides and amino acids , and their receptors .

副交感神经节前神经元位于延髓内的疑核、迷走神经背侧运动核和上述两核之间的网状结构。

The parasympathetic preganglionic neurons are located in the ambiguous nucleus , dorsal motor nucleus of the vagus nerve and reticular formation between the two above nuclei .

疑核，迷走孤束复合体，最后区，腹外侧延髓和中间网状结构共同组成了延髓内脏带。

NA , together with dorsomedial vagal-solitary complex , area postrema , ventrolateral medulla and intermediate reticular formation , forms the medullary visceral zone ( MVZ ) .

支配胃的迷走副交感神经纤维主要来自延髓的迷走神经背核，部分来自疑核。

The vagal parasympathetic neurons innervating the stomach are largely located in the dorsal motor nucleus of the vagus ( DMV ) and partly in the nucleus ambiguus ( NA ) .

大鼠疑核和迷走神经背核对胃酸、碳酸氢盐分泌影响的比较研究我还得核实一些疑点。

Comparative Studies on the Effects of Nucleus Ambiguus and Dorsal Motor Nucleus of Vagus on Gastric H ~ + and HCO_3 ~ - Secretion ; I have yet to check up some doubtful points .

结论：电刺激疑核对胃运动有显著的抑制作用，并且右侧疑核对胃运动的抑制程度比左侧疑核大。疑核对胃运动的抑制作用是通过迷走神经介导的。

Conclusion : NA inhibits gastric motility and the inhibitory degree of right NA is more than that of left NA , and the inhibitory effect is mediated by vagus .
