ABSTRACT

<p><b>OBJECTIVE</b>To study the primary effects of Niuhuang Qingwei wan on the gastrointestinal function in aninmal for justifying its efficacies in clinic.</p><p><b>METHOD</b>Mice were twice administered with Niuhuang Qingwei wan (0.83, 1.67, 3.33 g x kg(-1), ig) and rats were twice administered with Niuhuang Qingwei wan (0.59, 1.18, 2.36 g x kg(-1), ig). The effects on the stomach function were evaluated by the gastric emptying test in mice and the gastric analysis in rats. The effect on the intestinal function were evaluated by the propulsive motility of the total gastrointestinal tract test in mice by recording the time and frequency of excreting carbo medicinalis. Its analgesia was explored by using the abdominal constriction test induced by acetic acid.</p><p><b>RESULT</b>Niuhuang Qingwei wan decreased the activity and secretion of pepsin in a dose-dependent manner (P < 0.01, P < 0.05), the gastric juice volume at middle and high doses (P <0.01, P <0.05), and the gastric acid volume at high dose (P <0.05); However, it had no significant effects on the gastric emptying in normal mice and the acidity in gastric juice. It shortened the excreting time of feces and increased the frequency of defecation (P < 0.01, P < 0.05). It also inhibited abdominal constriction responses at high dose, and the inhibition rate was 40.0% (P <0.01).</p><p><b>CONCLUSION</b>Niuhuang Qingwei wan can promote gastrointestinal motility, decrease gastric acid volume and activity of pepsin and show certain analgesia effect. Those findings are consistent with its treating stomach heat in clinic.</p>
