Enzymatically degradable compositions containing biocompatible polymers reactive with glycosaminoglycan compositions having a first glycosaminoglycan compound having a first degree of acetylation and a second glycosaminoglycan compound having a second degree acetylation different than the first degree of acetylation.

A nozzle cap (1) is provided, which is formed from a rubber composition containing a rubber component including a diene rubber and a non-diene rubber, wherein the diene rubber is present in a proportion of 20 to 70 parts by mass based on 100 parts by mass of the total of the rubbers in the rubber composition. The nozzle cap (1) has a moderate gas transmission property and, hence, can be quickly sterilized by EOG sterilization and steam sterilization, quickly removed of residues by deaeration, and quickly dried in a shorter period after the steam sterilization. In addition, the nozzle cap (1) is less liable to be loosened due to increase in internal pressure and compression set and detached from the nozzle, and has a reduced leaching substance amount before and after the sterilization.

Biocompatible phase invertible proteinaceous compositions and methods for making and using the same are provided. Phase invertible compositions in accordance with the invention are prepared by combining a liquid proteinaceous substrate and a liquid crosslinking composition, where the liquid crosslinking composition includes a macromolecular crosslinking agent. Also provided are kits for use in preparing the subject compositions. The subject compositions, kits and systems find use in a variety of different applications.

An embolic material contains at least one type of polymer and a liposoluble contrast medium. A method for producing an embolic material includes extruding a raw material that is in a molten state into a solvent, and cooling the raw material so as to solidify the raw material. The raw material contains a polymer and a liposoluble contrast medium.

A soft film, a sponge, or a sheet in the dried state is provided, which is capable of forming a hydrogel absorbing water or blood. The film is obtainable by preparing a film-state material in the dried state from either a solution of poly(acrylic acid) or a solution of polyvinylpyrrolidone, and bringing the film-state material into contact with the other remaining solution, and then drying or freeze-drying it.
