Effects of Shengji Huayu Ointment on Total IL-1β,Collagen TypeⅠand Collagen TypeⅢin Granulation Tissue of Mice in Wound Repair Period / 中国药师

ABSTRACT

Objective:To investigate the mechanism of promoting wound healing of Shengji Huayu ointment. Methods: Db/db mice were divided into 5 groups according to the randomized block design: three Shengji Huayu ointment groups respectively at high (15 g·kg-1),middle (10 g·kg-1) and low(5 g·kg-1) dose,the positive control group(Beifuji) and the model control group, and balb/c mice were used in the normal control group,and each group was with 10 mice. The model of full-thickness skin defect in mouse skin was used,and after HE staining,IL-1β and collagen type I and type III in granulation tissue were observed by immunohis-tochemistry and image analysis. Results:HE staining showed that the wound healing was obvious in the high dose group and the mid-dle dose group. The expression of IL-1 β in each group was not obvious. The levels of collagen type I and type III in the three Shengji Huayu ointment groups were higher than those in the model control group (P<0.05).Conclusion: Shengji Huayu ointment can pro-mote wound healing and reduce scar formation in mice.
