一、胆道系统的神经调节与递质和受体 (一)胆碱能神经 不同程度地参与胆道运动和胆汁分泌功能的调节。刺激时一般可致胆囊和胆道收缩、胃泌素分泌等。 (二)肾上腺素能神经 胆道系统存在兴奋性α受体和抑制性β受体。不仅能影响胆道运动,亦可间接影响胆汁分泌。 (三)血管活性肠肽能神经(VIP Ergic Nerve)是抑制性神经,参与胆囊和Oddi氏括约肌的松弛反应。 (四)嘌呤能神经(Purinergic Nerve)对胆囊活动可能具有抑制性调节。
First, the biliary system of neuromodulation and neurotransmitters and receptors (a) cholinergic nerve to varying degrees, participate in the regulation of biliary tract motility and biliary secretion. When stimulated generally can cause gallbladder and biliary contraction, gastrin secretion. (B) the presence of excitatory alpha receptors and inhibitory beta receptors in the adrenergic nervous biliary system. Not only can affect the biliary movement, but also indirectly affect the bile secretion. (C) Vasoactive intestinal peptide nerve (VIP Ergic Nerve) is an inhibitory nerve involved in the relaxation of the gallbladder and Oddi’s sphincter. (D) purinergic nerve (Purinergic Nerve) gallbladder activity may have inhibitory regulation.
