Experimental Study on the Expression of IL-1β and bFGF in Wound Healing Process of Rabbit Cutaneous Infective Wound in Liu-He-Dan

Abstract EN

Objective.

This study applied Liu-He-Dan (LHD) to treat the infective wounds of rabbits to explore the mechanism of LHD in promoting wound healing.

Method.

Five circular infective incisions were generated on the back of each rabbit.

Wound dressings were performed every day since postoperative day 1.

Ten rabbits were euthanized on days 3, 7, 14, and 21.

Each specimen was divided into two parts, one was used for detecting interleukin-1 beta (IL-1β), and the other one was used for detecting basic fibroblast growth factor (bFGF).

Result.

The content of IL-1β in the model group was higher than those in the other groups (P<0.05).

The content of IL-1β in the treatment group was lower than the other groups on days 14 and 21.

The expression of bFGF in treatment group is significant on days 3, 7, and 14, compared with traditional Chinese medicine group and model group.

The expression of bFGF has no significant difference with Western group.

Conclusion.

The research approved that LHD could specifically suppress the expression of IL-1β and upregulate the expression of bFGF in the wound, decreasing the release of inflammatory factor of the infective wounds and promoting the healing of the infective wounds.
