Characteristics of Myoelectrical Activities along the Small Intestine and Their Responses to Test Meals of Different Glycemic Index in Rats.

CONCLUSIONS: In addition to the well-known frequency gradient, there is also a gradual decrease in the DP and spikes along the small intestine in the fasting state. Glucose and hyperglycemic meals inhibit myoelectrical activities in the proximal small intestine, but result in enhanced but more dysrhythmic intestinal myoelectrical activities. There is a significant negative correlation between the normality of intestinal slow-waves and blood glucose.
