Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.

此现象一来可推测，肝脏在遭受胆管阻塞性黄胆的伤害后，其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能，而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息，所以感觉神经元将一氧化氮制造量提升，有助於感觉讯息的快速传报，以发挥回馈调控的效果；二来可表示，自主神经系统不论是交感或副交感神经，为了因应胆管阻塞所造成肝脏的病变，以增加一氧化氮的制造，意欲刺激肝外胆道系统，排空滞留在肝脏内或胆囊内的胆汁，而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。
