为探讨兔消化间期胆囊位相性收缩（ＰＣＧＢ）与奥狄氏括约肌（ＳＯ）锋电位簇（ＣＳＰＳＯ）之间的关系，将动物禁食但自由饮水１５～１８ｈ 后，乌拉坦静脉麻醉。胆囊内置入装满生理盐水的蛙膀胱并与压力换能器（ＴＰ－２００Ｔ）相连以测胆囊内压，双极康铜丝电极引导ＳＯ肌电。结果：兔消化间期胆囊（ＧＢ）间断地位相性收缩，ＳＯ 锋电位簇集发放。每次ＰＣＧＢ总伴随１ 次ＣＳＰＳＯ，ＰＣＧＢ与ＣＳＰＳＯ存在１∶１ 对应关系（Ｙ＝０．９６２Ｘ＋ ０．５８７， ｒ＝ ０．９８２， Ｐ＜ ０．０１）。ＰＣＧＢ幅度与对应ＣＳＰＳＯ积分之间呈正相关（Ｙ＝ ０．０２５Ｘ＋ １．１３０，ｒ＝ ０．９６８， Ｐ＜ ０．０１）。提示兔消化间期ＧＢ及ＳＯ同步节律性地收缩与舒张，可能与ＧＢ更好地储存浓缩胆汁及胆总管的自净作用有关。
To investigate the relationship between PCGB and SOPS frontal potential cluster (CSPSO) during intergastric rabbits, the animals were fasted but were allowed to freely drink water for 15 to 18 hours after anesthesia with urethane. Gallbladder bladder filled with normal saline frog bladder and pressure transducers (TP-200T) connected to measure the gallbladder pressure, bipolar Kang electrode wire guide SO EMG. Results: The interphalangeal gallbladder (GB) of rabbit interpenetrated intermittently and the SO front potential cluster was distributed. There was a 1: 1 correspondence between PCGB and CSPSO in each PCGB accompanied by 1 CSPSO (Y = 0.962X + 0.587, r = 0.982, P <0.01). PCGB amplitude and the corresponding CSPSO score was positively correlated (Y = 0.025X + 1.130, r = 0.968, P <0.01). Prompt GB and rabbit during interphase GB and SO synchronous rhythmic contraction and relaxation may be related to GB better storage of concentrated bile and common bile duct self-purification effect.
