| 摘要 |
The invention provides a method of modulating proteases, particularly when treating a wound (for example, a chronic ulcerous skin lesion) in a human or non-human mammal (particularly a human). The medium containing the proteases (e.g. the wound) is contacted with a topical hydrogel composition comprising a hydrophilic polymer carrying multiple pendant sulphonyl groups, optionally with multiple pendant carboxylic groups, on each polymer molecule.
