It is an object to provide a therapeutic material for a skin ulcer which has excellent therapeutic effects on intractable skin ulcers such as decubitus ulcers with pockets and huge decubitus ulcers. By applying the therapeutic material for decubitus ulcers consisting of a fibrous material holding an antibiotic and a cell proliferation accelerator therein which is formed into an approximately spherical shape to a site of decubitus in a state in which a defect extending to the dermis, subcutaneous tissue, muscle or bone occurs, it is possible to treat critical skin ulcers such as intractable decubitus ulcers with pockets and huge intractable decubitus ulcers, as well as to treat not only relatively mild decubitus classified as stage II according to the US National Pressure Ulcer Advisory Panel (NPUAP) staging system, i.e., decubitus having ulcers in a state in which a part of the dermis is deficient, but also severe decubitus that has progressed to stage III to IV according to the NPUAP staging system, particularly decubitus with intractable ulcers with pockets or decubitus with huge intractable ulcers.

A plastic composition consisting essentially of plastic matter, inorganic matter, and organic matter. The plastic composition has a notched izod impact above 12 J/m, a surface energy of at least 40 dyne/cm and, and when the plastic composition is subjected to injection molding, at least one of a tensile strength of above about 2.7 MPa, a tensile modulus of above about 600 MPa, a flexural modulus above about 690 MPa, a flexural strength above about 5.6 MPa, and a Charpy Impact above about 1.5 KJ/m2.

The present disclosure provides an adhesive composition including a silicone-based adhesive and cellulose nanocrystals dispersed in the silicone-based adhesive. The present disclosure also provides an article including a substrate and a layer of the adhesive composition adhered to the substrate. Further, the present disclosure provides a method of making an adhesive composition. The method comprises mixing cellulose nanocrystals in a silicone-based adhesive to disperse the cellulose nanocrystals. The present disclosure additionally provides a method of making an article including disposing a layer of the adhesive composition on a substrate. The presence of the cellulose nanocrystals advantageously increases the water uptake capacity of the silicone-based adhesive while maintaining acceptable adhesive performance.
