title: [Effects of dingduwan on electric activities of gastrointestinal smooth muscle and effect of gastrointestinal motility].
abstract: Dingduwan (DDW) is a Chinese herbal medicine. Method of modified synchronous recording was used to study the electric activities of gastrointestinal (GI) smooth muscle and the effect of GI motility treated by DDW. A dosage of 3.5 g/kg for ingestion in rats markedly increased the average amplitude of GI slow wave, the total amplitude of GI motion, the rate of GI slow wave and intestinal motion (P < 0.05), but it had no significant effects on the frequency of gastroelectric slow wave and gastric motility (P < 0.05). DDW in the dosage of 5.2 g/kg for ingestion markedly promoted the recovery of intestinal intussusception in mice (P > 0.05). The results showed that DDW markedly increased the intestinal electricity and motility more than that of stomach.
