颈动脉小体(CB)感觉动脉血中的缺氧、高碳酸血症和酸中毒。由此导致延髓孤束核的CB神经输出(CBNO)增加,促进呼吸、循环、肾脏和内分泌系统的反射反应。CBNO的增加通常被认为是由于CB中的球细胞释放神经递质所致。除了这些释放的递质对毗邻球体细胞的突触后传入神经元的作用外,这些递质还作用于球体细胞的自体感受器。在球体细胞所含的几种递质中,现在有相当多的证据支持乙酰胆碱(ACh)和三磷酸腺苷(ATP)的兴奋作用以及多巴胺(DA)和去甲肾上腺素(NE)的抑制作用(Fitzgerald,2000)。ACh(Fitzgerald等人,1999;Kim等人,2004)和儿茶酚胺(Wang和Fitzgerald,2002)的释放似乎受到调节剂的影响。本研究探讨了腺苷(ADO)对ACh、DA和NE释放的影响,因为有报道称ADO影响CBNO(McQueen和Ribeiro,1981)和CB介导的通气量增加(Monteiro和Ribeiro,1987)。这项研究进一步研究了一氧化氮(NO)对ACh释放的作用,因为有报道称NO可以减少缺氧诱导的CBNO增加(Wang,et al.,1994)。
AbstractThe Carotid Body (CB) senses hypoxia, hypercapnia, and acidosis in the arterial blood. The resulting increase in CB neural output (CBNO) to the nucleus tractus solitarius in the medulla promotes reflex responses in the respiratory, circulatory, renal, and endocrine systems. Increases in CBNO are commonly thought to be due to the release of neurotransmitters from glomus cells in the CB. Additional to the action of these released transmitters on the postsynaptic afferent neurons which abut on the glomus cells the transmitters act presynaptically on glomus cell autoreceptors. Among the several transmitters contained in the glomus cells there now exists considerable evidence supporting excitatory roles for both acetylcholine (ACh) and ATP and an inhibitory role for dopamine (DA) and norepinephrine (NE) (Fitzgerald, 2000). The release of ACh (Fitzgerald et al., 1999; Kim et al., 2004) and catecholamines (Wang and Fitzgerald, 2002) appears to be influenced by modulators. The present study investigated the action of adenosine (ADO) on the release of ACh, DA, and NE since it has been reported that ADO influences CBNO (McQueen and Ribeiro, 1981) and CB-mediated increases in ventilation (Monteiro and Ribeiro, 1987). The study further investigated the action of nitric oxide (NO) on the release of ACh since NO has been reported to reduce the hypoxia-induced increase in CBNO (Wang, et al., 1994).
