The caerulein-induced decrease of intragastric Pressure is abolished or reversed to increase by severanse of GVN.In vitro,caerulein Produced an excitatory effect on the isolated gastric longitudinal muscule stips. The effect was abolished by atropi- ne.The results suggest that caerulein produce both inhibition and excitation the gastric movement,and that the formet is induced throgh the GVN,while the latter cholinergic neuron in the enteric ne- rvous system.The inhibition effect is predominant in vivo.

用以氨基甲酸乙酯麻醉的大鼠分析了雨蛙肽对体内和离体胃运动的不同效应。静脉注射雨蛙肽(60ng/kg)引起胃内压的下降和迷走神经胃支离中活动的同步减少。但是,全部切断迷走神经胃支后雨蛙肽对胃运动的效应抑制消失或反转为兴奋效应。雨蛙肽对离体胃肌条片的运动则有刺激作用。这种效应被阿托品所消除。根据以上结果认为,雨蛙肽对整体内的胃运动有抑制和兴奋二种效应。前者主要通过迷走神经,而后者则直接刺激胆硷能壁内神经元而实现的。在整体内,两蛙肽对胃运动的抑制作用占优势,其兴奋性影响不易显现。

Effects of stimulation of locus coeruleus (LC) on gastroelectrical activity andgastric motility were studied in rats under urethane anaesthesia. Following stimu-lation, the blood pressure was elevated 60.5+3.4mmHg (P<0.001), while theamplitude of the slow waves of electrogastrogram was diminished from controlvalue of 0. 52mV to 0. 18mV with little change of frequency. The fast waves weredecreased both in frequency and amplitude. Intragastric pressure was decreasedto 29.9% of the control value (P<0.001)....

Effects of stimulation of locus coeruleus (LC) on gastroelectrical activity andgastric motility were studied in rats under urethane anaesthesia. Following stimu-lation, the blood pressure was elevated 60.5+3.4mmHg (P<0.001), while theamplitude of the slow waves of electrogastrogram was diminished from controlvalue of 0. 52mV to 0. 18mV with little change of frequency. The fast waves weredecreased both in frequency and amplitude. Intragastric pressure was decreasedto 29.9% of the control value (P<0.001). After transection of cervical cord,stimulation of LC caused only an increase of 9 mmHg in blood pressure and a pro-longation of the latency of the pressor response, while the amplitude of slow wavesof electrogastrogram decreased from control value of 0.53mV to 0.24mV andintragastric pressure decreased to 45. 1% of the control value. These residualinhibitory effects were completely abolished by subsequent bilateral vagotomy. Inthe animals subjected to vagotomy only, while keeping spinal cord intact, stimulationof LC also reduced the intragastric pressure by 36.6%. It is suggested that theLC may be involved in the central regulation of electrical and mechanical activitiesof stomach, the effect heing mediated through both spinal and vagal pathway.

用乌拉坦麻醉的大鼠,同步描记血压、胃电和胃运动,观察了刺激蓝斑核区对胃电和胃运动的影响,分析了其作用途径。实验结果表明,刺激蓝斑核区后血压平均升高60.5mmHg(P<0.001);胃电慢波的振幅由对照的0.52mV 减弱到0.18mV(P<0.001)。快波的振幅和频率也减少。胃内压平均下降到对照值的29.9%(P<0.001)。在横断颈髓的动物刺激蓝斑核区后血压的升高幅度明显减弱,平均升高9mmHg,升压效应的潜伏期明显延长;胃电慢波的振幅由对照的0.53mV 减弱到 0.24mV(P<0.001)。胃内压平均下降到对照值的45.1%。对胃电和胃运动的这种抑制效应可被切断迷走神经所完全消除。在事先切断迷走神经但脊髓仍保留完整的动物,刺激蓝斑核区使胃内压平均下降36.6%(P<0.01)。根据以上结果认为,蓝斑核区可能参与对胃电和胃运动的中枢性调节。此调节机制可能经由脊髓和迷走两条通路实现。

The results obtained are as follows: In the control group, the amplitude of the slow wave and intragastric pressure were decreased to 42.31+9.79% and 34.59±10.20% respectively by stimulation of locus coeruleus. However, in the group treated with 6-OHDA the amplitude of slow wave and intragastric pressure were decreased to 84.14+10.13% and 62.86±7.19% respectively. The difference between the two groups was statistically highly significant(p<0.01). The result suggest that the central noradrenergic inhibitory mechanism is involved in the regulation of gastric electrical activity and gastric motility.

电刺激蓝斑核可抑制胃电和胃运动。我们先以6-羟基多巴胺(6-OHDA)损毁大鼠(已用乌拉坦麻醉)的灰部深翼肾上腺素能神经,然后观察了这种损坏对上述抑制效应的影响。结果表明,在对照组,电刺激蓝斑核导致胃电慢波的振幅和胃内压分别下降到对照值的42.31±9.79%和34.59±10.20%。但是,在注射6-OHDA组,刺激蓝斑核后胃电慢波的振幅和胃内压分别下降到对照值的84.14±10.13%和62.86±7.19%,注药组的抑制效应明显弱于对照组,(P<0.01)。本文结果提示:灰翼区肾上腺素能神经参与由刺激蓝斑核区引起的胃电和胃运动的抑制机制。
