[Effect of sound waves on motor activity of the stomach, small intestine and gallbladder].

In the chronic experiments on 20 dogs, it was established that influencing by the acoustic waves with the frequency by the acoustic waves with the frequency of 0.2-0.3 kHz, intensity of 0.24-0.28 W/cm2 for 10-15 min upon the duodenal region led to decrease in the motor activity of the gastric body, antrum, duodenum, jejunum, gallbladder. Influencing by the acoustic waves with the frequency of 2.0-3.0 kHz, intensity of 0.57-0.73 W/cm2 for 10-15 min upon the duodenal region led to increase in the motor activity of the pylorus, duodenum, jejunum, gallbladder, and depression of motility of the gastric body.
