A wound dressing which comprises a carrier layer having a non-adherent to cell layer on a wound facing surface thereof. The non-adherent layer has bonded thereto a biodegradable cell anchoring layer which anchors mammalian cells. In use, the degradable layer breaks down releasing the cells into the wound site which are discouraged from reattaching to the dressing by the non-adherent layer. Thus the dressing can switch from a cell binding state to a state in which the binding of cells is discouraged. Systems, methods of treatment and methods of manufacturing the dressing are also disclosed.

Gloves, especially those of the type worn by surgeons, and fabricated from elastomeric materials have a hand conducting surface comprising an ionic polyurethane to render the glove hypoallergenic. The surface modifying composition may comprise a blend of an ionic polyurethane and a second polymer, e.g. another polyurethane or an acrylic polymer wherein the particle size of the second polymer are greater than that of the base ionic polyurethane. The use of blends enables donning of the glove to be effected without the aid of donning powder such as starch or talc.
