Effects of Electroacupuncture on Motility of the Castro-intestinal Tract of Dogs

전침자극이 개의 위장관운동에 미치는 영향

Gastro-intestinal mortility and transit time of barium sulfate after electroacupuncture were investigated in normal dogs and administration of xylatine in dogs. Electroacupuncture was performed with a current of 1.5 volt and 20 Hz at the acupoints of Tsu San Li(right(+) left(-) in dogs for 30 minutes. The results were as follows: 1. After electroacupuncture stimnlation in normal dogs, rates of stomach contractions was not changed, but amplitudes of stomach motility was markadly increased. The electroacupuncture stimulation tasted about 60 minutes after the end of electroacupuncture. 2. The stomach contractions was markedly increased, while the amplitudes of stomach motility was sligltly decreased by the administration of xylazine in dogs. 3. The rates of stomach contractions and amplitudes of motility were markedly increased after administration of xylazine in the electroacupuncture stimulated dogs. 4. Gastric emptying time o barium sulfate after electroacupuncture stimulation in dogs was highly significantly decreased compared with that of normal dogs(p < 0.01). 5. Small bowel transit time of barium sulfate after electroacupuncture stimulation in dogs was highly significantly decreased compared with that of normal dogs (p < 0.01). 6. Gastroduodenal transit time of barium sulfate after administration of xylazine following electroacupuncture stimulation dogs was blighty significantly decreased compared to that of dogs dosed with xylazine (p< 0.01). 7. Small bowel transit time of barium sulfate after administration of xylazine following electroacupuncture stimulation dogs markedly decreased compared to that of dogs dosed with xylazine (p < 0.05).
