Abstract

Objectives : This study was designed to investigate effects of electro-acupuncture's stimulated frequency, intensity, duration at 5736 on tile Small Intestine Motility in Rats. Methods The motor activity of small intestine in rats was evaluated by intestinal transportation rate. Changes in tile motility of ileum in vivo was measured at 10 minutes after electro-acupuncture. Various kinds of stimulus-frequency were used in this experiment: 2 Hz, 50 Hz, 100 Hz, 2 Hz-4 trains, 8 Hz groups treated with EA of the condition in S mA, 1 ms pulse duration, 30 minutes stimulated duration. Three different stimulus-intensity were used: 1, 5, 10 mA groups treated with EA of the condition in 2 Hz, 1 ms pulse duration, 30 minutes stimulated duration. Six different stimulus-duration were used: 10, 20, 30, 40, 50, 60 minutes groups treated with EA of the condition in 2 Hz, 5 mA, 1 ms pulse duration. Results : 2 and 100 Hz groups significantly increased the small intestine motility, but 50 Hz group did not induce a significant change. Besides, small intestine motility was significantly increased only in 5 mA intensity (5 times twitch). futhermore, at least 20 minutes EA treatment was necessary to increase the small intestine motility. Conclusion : Those basic data form this study can be applied to established the effective treatment of EA for gastrointestinal diseases in the clinical field.
