Abstract
Abstract A method for treating cutaneous and corneal wounds as well as certain microbial-related diseases comprises topically applying a defensin peptide to the affected tissue. The compositions comprise a natural, synthetic, or analog defensin molecule having both a mitogenic activity capable of stimulating cell growth and an antimicrobial activity capable of inhibiting the growth of a wide variety of pathogens. In addition to therapeutic use, the defensins are useful as mitogens in cell and tissue culture media.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
31 words
A method for treating wounds in mammalian tissue to promote healing, said method comprising applying a defensin peptide to the wound in an amount sufficient to promote healing of the wound.
Claim 2
Independent Claim
31 words
A method for treating wounds in mammalian tissue to promote healing, said method comprising applying a defensin peptide to the wound in an amount sufficient to promote healing of the wound.
Claim 3
Dependent Claim
17 words
A method as in claim 1, wherein the defensin peptide is applied to a corneal epithelial wound.
Claim 4
Dependent Claim
19 words
A method as in claim 2, wherein the defensin peptide is applied to a corneal epithelial or stromal wound.
Claim 5
Dependent Claim
29 words
A method as in claim 2, wherein the defensin peptide is present in a physiologically-acceptable carrier at a concentration in the range from about 1 nM to 10 mM.
Claim 6
Dependent Claim
31 words

Claim 7
Independent Claim
30 words
A method for treating corneal wounds and keratitis, said method comprising applying a defensin peptide to the eye of an affected host in an amount sufficient to effect said treating.
Claim 8
Independent Claim
30 words
A method for treating corneal wounds and keratitis, said method comprising applying a defensin peptide to the eye of an affected host in an amount sufficient to effect said treating.
