The effect on mucosal pathohistological grading was 2.00±0.84 and 0.91±0.46 in mild UC (P〈0.001), and 2.49±0.84 and 1.31±0.75 in moderate UC (P〈0.001) before and after treatment.CONCLUSION: SASP can improve small vessel lesions and crypt abscesses and reduce neutrophilic and eosinophilic leukocyte infiltration in inflammatory mucosa of UC.展开更多
