Objectives: To clarify the effects of Jungri-tang Gamibang on accelerating small intestinal movement induced by the stimulation of cholinergic neurotransmission. Methods: 500, 250 and 125mg Jungri-Tang Gamibang or 20mg domperidone were dissolved or suspended in distilled water and orally pretreated on the carbachol-accelerated small intestinal transit mice once a day for 7 days at a volume of 10ml/kg (of body weight) using a Zonde needle attached to 1 ml syringes containing test drugs. Result: Significantly (p<0.01) increase of % regions of activated charcoal transit in the small intestine was detected in carbachol control compared to that of intact control. However, significant (p<0.01) decreases of % regions of activated charcoal transit were dose-dependently observed in all Jungri-Tang Gamibang extracts or domperidone-pretreated groups. Conclusions: it was concluded that Jungri-tang Gamibang enhancement in the normal intestinal motility and normalization in the accelerated intestinal motility might interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilization of calcium ions required for smooth muscle contraction non-specifically.
