The vagus nerve was examined electromyographically for effect on the abomasal movement in adult female goats subjected to dorsal or truncal vagotomy. The results obtained are summarized as follows. 1. After dorsal vagotomy, the discharge interval prolonged slightly and the propagation velocity decreased. 2. After truncal vagotomy, the propagation velocity did not show a remarkable change except that the discharge interval showed a tendency to prolong slightly. 3. Neither dysrhythmia nor antiperistaltic discharge was seen after dorsal or truncal vagotomy. 4. The movement of the reticulum showed a tendency to be affected with temperature after dorsal vagotomy. It was not recorded after truncal vagotomy. The goats vagotomized dorsally showed an increase in body weight and decrease in volume of feces accompanied with repeated bloat. The goats vagotomized truncally died of acute frothy bloat 2-10 days after operation. Therefore, it was suggested that truncal vagotomy might have exerted a greater effection all the stomach of the ruminant than dorsal vagotomy, which reduced the movement of rumen more remarkably than the movement of the abomasum.
对接受背部或迷走神经干切断术的成年雌性山羊,通过肌电图检查迷走神经对皱胃运动的影响。所得结果总结如下:1. 背部迷走神经切断术后,放电间隔略有延长,传导速度降低。2. 迷走神经干切断术后,除放电间隔有轻微延长趋势外,传导速度未见明显变化。3. 背部或迷走神经干切断术后均未出现心律失常或逆蠕动放电。4. 背部迷走神经切断术后,网胃运动有受温度影响的趋势。迷走神经干切断术后未记录到该情况。背部迷走神经切断的山羊体重增加,粪便量减少,并伴有反复腹胀。迷走神经干切断的山羊在术后2 - 10天死于急性泡沫性臌气。因此,提示迷走神经干切断术对反刍动物整个胃的影响可能比背部迷走神经切断术更大,背部迷走神经切断术对瘤胃运动的影响比皱胃运动更显著。
