In addition, the effects of the four components of HHT, that is, Gardeniae Fructus(GF), Scutellariae Radix(SR), Coptidis Rhizoma(CR), and Phellodendri Cortex(PC), on GI motility were also investigated.RESULTS In normal ICR mice, ITR% and GE values were significantly and dose-dependently increased by the intragastric administration of HHTE(0.1-1 g/kg). The ITR% values of GMD mice were significantly lower than those of normal mice, and these reductions were significantly and dose-dependently inhibited by HHTE(0.1-1 g/kg). Additionally, GF, CR, and PC dosedependently increased ITR% and GE values in normal and GMD mice.CONCLUSION These results suggest that HHT is a novel candidate for the development of a gastroprokinetic agent for the GI tract.展开更多
