  • Patent number: 7517528
    Abstract: Epidermal growth factor (EGF) produced by an excretory recombinant approach was tested for its efficacy in treating various skin wounds. In a randomized double blind controlled study, local cream samples prepared with human EGF at a final concentration of as low as 0.02% (g/g) in topically suitable carrier were found to have an enhancing effect on the recovery of diabetes foot ulcers. This promotional effect is statistically significant and has resulted in a reduced mean healing time of over 3 weeks when compared with that of control. Both the 0.02% (g/g) and 0.04% (g/g) human EGF supplemented samples in comparison with control showed a trend of stimulatory effect when a recovery of 50% of an ulcer was considered. The EGF samples were also shown to be highly effective in promoting treatments of wounds resulting from bedsores and surgeries.
