4 dogs weight 15-20 kg were used.The unanesthetized trained dogs with implanted bipolar electrode in the stomachduodenum wall were prepared for the study of the droperidoli effect on the visceral traction response.The results were as follows:Pulling the stomach caused a disturbance and a slowdown of BER of the stomach and the inhibition of the fast wave,the frequencies of the duodenum were increased. The stomach was pulled,after the injection of dropenidoli,the time of disturbance of BER and the frequencies of the fast waves of the stomach and doudenum were inhibited.These results suggest that droperidoli effect should be used mainly to suppress such visceral traction responses as nausea,vomit- ing,etc.

本文用慢性实验方法,以胃肠电活动作指标,观察了氟哌啶对内脏牵拉反应的影响。用双极电极缝于胃及十二指肠浆膜,引导胃肠电。在胃贲门部肌层埋植牵拉环,作牵拉内脏用。结果表明,注射氟哌啶后牵拉胃,引起胃的基本电节律紊乱时间缩短,胃及十二指肠快波恢复受到抑制。结果提示,氟哌啶对内脏牵拉反应如恶心呕吐等具有明显的抑制效应。

The present study reports a new pattern of electrical activity of the gastrointestinal tract,which is chara- cterized by both of the discrete spike bursts that migrate down on the small intestine at an ultra-rapid speed(58.8± 28.6cm/sec.)and the much inhibited slow wave of the intestine,and which we call‘Ultra-rapid Propating Bursts of Spikes(UPBS)”.This pattern of electrical activity could be classified into 2 types.The Type Ⅰ is characte- rized by special intestinal spike acti- vity periods of 3.1±1.3minutes...

The present study reports a new pattern of electrical activity of the gastrointestinal tract,which is chara- cterized by both of the discrete spike bursts that migrate down on the small intestine at an ultra-rapid speed(58.8± 28.6cm/sec.)and the much inhibited slow wave of the intestine,and which we call‘Ultra-rapid Propating Bursts of Spikes(UPBS)”.This pattern of electrical activity could be classified into 2 types.The Type Ⅰ is characte- rized by special intestinal spike acti- vity periods of 3.1±1.3minutes which are caused by one burst of spikes in the stomach.The Type Ⅱ is character is that the gastric spike bursts initiate the ultra-rapid spikes in the intestine one by one. The UPBS occurred spontaneously in 4 fast dogs(5 times),and were induced by Erythromycin at doses of, at least 200ug/kg,in 32.7% trials(18 times).The UPBS's activity may last more than 250 minutes,and then spontaneously transfer into Migrating Myoelectric Complex(MMC),or be replaced by the digestive activity pattern after feeding.We conclude that the UPBS may be a different myo-electric pattern of the gastro- intestinal tract from MMC,in the interdigestive state of dogs.

本文报告一种新的胃肠电活动类型,其特征为,断续发放的锋电簇沿小肠超速(58.8±28.6cm/秒)扩布,锋电簇可发生于小肠慢波的不同部位,且对慢波呈强烈抑制。根据小肠锋电簇的发放与胃锋电活动的关系,可将其分为两类,即Ⅰ型和Ⅱ型。超速扩布锋电簇可在禁食狗自发产生,也可在32.7%实验中被红霉素诱发而产生。这类活动可持续250分钟以上逐步转化成移行性综合肌电活动,也可因进食而转化成消化期电活动。因此,超速扩布锋电簇是狗消化间期中未被描述过的一种新的胃肠电活动类型。

We studied the effect of erythromycin (EM) on the migrating myoelectric complex (MMC)in dogs and found that 30-40 min after phase-Ⅲ occurring in the duodenum, intravenous injection of EM lactobionate at doses of 50-400μg/kg induced dose-dependent premature phase Ⅲ in 3-7 min, which were quite similar to the spontaneous phase Ⅲ in the frequency of spike bursts, migrating velocity and duration. Injection of EM 500μg/kg into the stomach and duodenum also initiated premature phase Ⅲ with latent periods of 24.5 ±...

We studied the effect of erythromycin (EM) on the migrating myoelectric complex (MMC)in dogs and found that 30-40 min after phase-Ⅲ occurring in the duodenum, intravenous injection of EM lactobionate at doses of 50-400μg/kg induced dose-dependent premature phase Ⅲ in 3-7 min, which were quite similar to the spontaneous phase Ⅲ in the frequency of spike bursts, migrating velocity and duration. Injection of EM 500μg/kg into the stomach and duodenum also initiated premature phase Ⅲ with latent periods of 24.5 ± 7.5 min and 23.7 ± 2.2 min respectively. Atropine pretreatment abolished EM-in-duced phase Ⅲ, but vagotomy did not. In a period of at least 70-250 min following premature phase Ⅲ, there was post-inducing effect of EM on the myoelectric activity, including shortened or prolonged MMG cycles, ectopic phase Ⅲ, even complete disruption of MMC and replacement of MMC by ultrarapid propagating bursts of spike activity. Anyway, EM had no effect on the gastrointestinal myoelectric activity in the digestive state of dogs.We consider that the side effect of EM on the gastrointestinal tract is associated with the premature phase HI and post inducing effect of EM. To induce phase Ⅲ, EM must be absorbed into the systemic circulation and exerts effect on the enteric cholinergic plexus.

以移行性综合肌电(MMC)作指标,研究红霉素(EM)消化道副作用与平滑肌电活动的关系。结果发现,在狗消化间期,静脉注射EM50~400μg/kg,在3~7min内即诱发剂量依赖性早发MMCⅢ相。此早发Ⅲ相起于胃、十二指肠,向小肠尾端移行,其锋电发生率、Ⅲ相持续时间和移行速度等均与自发Ⅲ相类似。胃、十二指肠内分别注射EM500μg/kg,经24.5±7.5min和23.7±2.2min才诱发移行性Ⅲ相。双侧膈上迷走神经切除后,EM仍诱发早发Ⅲ相,但其移行速度减慢(p<0.01),阿托品能阻断EM诱发Ⅲ相的发生。EM在Ⅲ相诱发后的70~250min甚至更长时间内仍使MMC周期和Ⅲ相起始紊乱,甚至完全破坏MMG,代之以超速扩布锋电簇活动。EM不影响进食后狗的胃肠电活动。因此,EM消化道反应的发生可能与其被吸收进血液后通过内在胆碱能神经启动早发Ⅲ相及其后较长后效应有关。
