title: [Experimental study on interdigestive migrating contractions with intestinal transection and injection of Ringer solution into intestine].
abstract: The occurrence and mechanism of IMC are still not completely elucidated. Base on the conjecture of that the region of intestine and its ingredients may be concerning with the conduction mechanism of IMC, following experiment was performed by author. Small intestine was cut into two parts. Anal side was closed as blind end, and the end of oral side was sutured to colon or anal part of intestine by end to side anastomosis. Gastric fistula and intestinal fistula of the blind ending intestine were also made, and six pieces of force transducers were sutured to the serosa of the intestine in order to observe the movement of intestine. Under non-anesthesia and non-restricted condition for whole day long, Ringer solution was injected into gastric or intestinal fistula by 50 ml one shot or continuous dripped infusion of 250 ml per hour. The result is: In upper part of intestine, the appearance of IMC in oral and anal side of intestine is continuously observed. However, in lower part of intestine, the IMC of oral and anal part of intestine appeared completely independent without any continuity. And, as one shot of 50 ml of Ringer solution was injected, the conduction of IMC was suppressed but still observable, while continuously infused of 250 ml/hr, the IMC was completely disappeared.
