Summary.

The factors participating to the wound healing are complex and still obscure. Among these factors, epidermal growth factor (EGF) and histamine by increasing reepithelization and reparation tissue strength via enhancing collagen deposition to the wound site have a beneficial effect. This study was performed to investigate the effect of EGF dosage forms on the histamine content of the experimentally induced wound and some wound healing criters in the mice.

Histological investigation of reepithelization, wound tensile strength for healing and collagen maturation, and histamine levels were assessed in the present study. Thirty two mice were divided into control, and EGF treated groups. Controls included three subgroups; untreated (n=5), 0.9% NaCl applied (n=5), and gel applied (n=5). Experimental groups were treated with two forms of EGF; EGF, solution form in 0.9% NaCl (n=5) and the gel form in 0.2% w/w in carbopol 940 (n=7). The discrepancy between these forms were evaluated. This evaluation was done by the application of two forms of EGF for 15 days on experimentally induced wound healing.

Gel form of EGF by sustained release from bioadhesive polymer is found to be more effective than the soluble form, on the healing of the wound, by acceleration of reepithelization and increment of wound tensile strength. The tensile strength of the wound indicates the rate of repair and collagen maturation. It has been observed that when physiological saline and carbopol 940 exposed to incision without EGF causes a significant increase in tissue histamine content.

According to the results of the present investigation; the histamine content is found to be decreased by EGF gel dosage form treatment, therefore preventing abnormal collagen formation has a beneficial effect on wound healing.
