目的 :研究家兔Ｏｄｄｉ括约肌 (ＳＯ)中ＮＯＳ阳性神经元的形态和生理特征。方法 :首先应用ＮＡＤＰＨ -ｄ组织化学法显示家兔ＳＯ中ＮＯＳ阳性神经元和其纤维的分布 ;另外 ,研究ＮＯＳ抑制剂ＮＧ-硝基 -Ｌ -精氨酸 (Ｌ -ＮＮＡ)及一氧化氮生成所需底物Ｌ -精氨酸对ＳＯ肌电活
Objective: To investigate the morphological and physiological characteristics of NOS positive neurons in sphincter of Oddi (SO) in rabbits. Methods: NADPH-d histochemical method was used to display the distribution of NOS positive neurons and their fibers in rabbit SO. In addition, the effects of NOS inhibitor NG-nitro-L-arginine (L-NNA) and nitric oxide Generate the required substrate L - arginine for SO myoelectrification
