[Effects of Fuhuang Shengji Yuchuang Ointment on expressions of types I and III collagens in granulation tissue of wound in rats with diabetes].
OBJECTIVE
To observe the effects of Fuhuang Shengji Yuchuang (FHSJYC) Ointment, a compound traditional Chinese herbal medicine, on the expressions of types I and III collagens in granulation tissue of wound in rats with diabetes.


METHODS
Fifty-four male Wistar rats were randomly divided into three groups: wound control group, normal saline (NS) group and FHSJYC Ointment group. Diabetes was induced by injection of 1.5% alloxan and oral gavage of 5% glucose, and skin wound was made in rats of the NS group and the FHSJYC Ointment group. Skin wounds of the rats in the FHSJYC Ointment group were treated with FHSJYC Ointment gauze dressing, while those in the NS group were treated with NS gauze dressing once daily. The rats were executed in turn on the third day and the eleventh day of the treatment, and the changes of the content of types I and III collagens in the wound granulation tissue were observed by immunohistochemical technology.


RESULTS
Compared with the NS group, the wound closure index in the FHSJYC Ointment group was increased (P<0.05). After 3-day treatment, the expression of type I collagen showed no significant differences among the three groups, while the expression of type III collagen in the FHSJYC Ointment group was higher than that in the NS group (P<0.05), similar with that in the wound control group. After 11-day treatment, the expressions of both types I and type III collagens in the FHSJYC Ointment group were higher than those in the NS group (P<0.05), similar with those in the wound control group.


CONCLUSIONS
FHSJYC Ointment can affect the process of wound healing by promoting and regulating the expressions of types I and III collagens.
