experimental group number

Results The bacterial species in each sample were the same as that of colon contents. The bacteria-colony number of each sample in the experimental group was lower than that in control(P<0.01).

结果：标本中生长的细菌与大肠内容物培养细菌种类相同，实验组标本的菌落数少于对照组（P<0，01）。

Results Sprout number of DRG in experimental group rats decreased obviously and the symptom of hyperalgesia was improved as compared to control rats.

结果实验组大鼠drg内交感芽生明显减少，热痛过敏症状被抑制。
