Methods: The model of skin incised wounds in mice was established. The wounds were treated with compound phenytoin sodium low and high dosage (4.25,4.55 g.kg-1) for 12 days, respectively, at 3, 6, 8, 12 days later, the skin wound healing rate of mice was observed. The model of cutaneous wound healing in rats was established. Staphylococcus aureus infection was induced by compound phenytoin sodium gel in low and high dose (1.70,1.82 g.kg-1) For 12 consecutive days, the wound healing rate of the rat skin was observed, and the histopathological examination of the healing tissue was performed. Results: At 3, 6, 8, 10, 12 d, the contractile rates of wounds of mice treated with low dose and high dose of phenytoin sodium gel were (20.16 ± 5.78)%, (40.02 ± 9.79)% and (71.04 ± 7.27) %, (96.14 ± 2.53)%, (99.44 ± 1.30)%, (28.50 ± 4.77)%, (55.66 ± 8.39)%, (79.67 ± 5.11)%, (96.14 ± 2.53)%, (100.00 ± 0.00)%, , Which was significantly higher than that of the gel matrix group (16.77 ± 4.79)%, (29.95 ± 5.63)%, (50.69 ± 4.19)%, (67.47 ± 5.13)% and (82.48 ± 4.40)% , P <0.01, P <0.01; P <0.01, P <0.01, P <0.01, P <0.01, P <0.01). The healing rates of the compound phenytoin sodium gel low and high dose groups were (29.45 ± 5.11)%, (50.17 ± 4.29)%, (72.48 ± 5.05)%, (87.44 ± 4.11)%, (96.66 ± 3.75)%, (33.71 ± 3.43)%, (58.67 ± 5.59)%, 81.86 ± 4.15%, 95.92 ± 2.39% and 100.00 ± 0.00% were significantly higher than that of the gel matrix group (20.71 ± 3.58)%, (40.42 ± 3.89)%, (58.53 ± 6.21)% and (74.71 ± 9.23)%, (86.47 ± 7.15)% (all P <0.01). Conclusion: Compound phenytoin sodium gel can promote wound healing of experimental bacterial infection.
