<p>Compositions for facilitating the healing of wound: (i) Finely divided chitin, partially depolymerized chitin, a deriv. of chitin, or a mixture of these. (ii) Finely divided egg-shells free of membrane, or a mixture of finely divided egg-shells and finely divided egg-shell membranes. Chitin has cicatrising properties as good as those of cartilage, but is more easily obtainable and of more standardized properties. Egg-shells are also efficacious for cicatrising; egg-shell membranes alone, previously used, are difficult to obtain free of shell.</p> |
