Effects of traditional Chinese herbal medicine San-HuangXie-Xin-Tang on gastrointestinal motility in mice

AIM: To investigate the effects of San-Huang-Xie-XinTang(SHXXT), a herbal product used in traditional Chinese medicine, on gastrointestinal(GI) motility in mice.METHODS: The in vivo effects of SHXXT on GI motility were investigated by measuring the intestinal transit rates(ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction(GMD).RESULTS: In normal ICR mice, ITRs were significantly and dose-dependently increased by SHXXT(0.1-1 g/kg). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. The ITRs of GMD mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by SHXXT(0.1-1 g/kg).CONCLUSION: These results suggest that SHXXT is a novel candidate for the development of a prokinetic agent that may prevent or alleviate GMD.
