Methods The experimental model of mice with PDS was induced by rhubarb decoction. Then the mice were treated with three dosages of SJZD (12.5, 25, and 37.5 g/kg), respectively. The body weight, body temperature, mean retention time of chyme in digestive tract, gastric emptying velocity, gastrin and motilin levels, and visceral index of mice were measured.

方法大黄煎液制备小鼠脾虚证模型后，以3种剂量(12.5、25、37.5g/kg)的四君子汤进行治疗，测定小鼠体重、体温、消化道内食糜平均滞留时间、胃排空速率、胃泌素与胃动素水平、脾脏和胸腺脂数。

Results Being compared with the normal group, the PDS mice showed a slower growth of body weight and a lower body temperature, a shorter mean retention time of chyme in digestive tract and faster gastric emptying velocity, a lower gastrin content, and a higher motilin content. Also splenic and thymus indexes were found to follow a downtrend in the PDS mice. Three dosages of SJZD showed a restoration effect on the above all indexes, and the high dosage was the most effective one, especially.

结果脾虚证小鼠体重增长缓慢，体温降低、消化道内食糜平均滞留时间缩短、胃排空加快、胃泌素的量降低、胃动素的量升高，脾脏和胸腺指数降低。3种剂量的四君子汤对脾虚证小鼠以上各指标的变化均有明显的矫正作用，以高剂量效果最佳。
