A tissue sealant for use in surgical and medical procedures for sealing the tissues of a living mammal is provided. The tissue sealant comprises a hydrogel which is formed by gelation of a premix disposed on the tissue to be sealed. The premix comprises alkylated chitosan or a gelatin, and a polybasic carboxylic acid or an oxidized polysaccharide, in an aqueous medium. The premix can also include a dehydrating reagent, a carboxyl activating reagent, or both. A specific use of the tissue sealant is in the repair of the dura mater after brain surgery to prevent leakage of cerebrospinal fluid. The tissue sealant may include a therapeutic or protective agent such as an antibiotic or an anti-inflammatory drug.

A fiber layer containing a fiber assembly and a liquid preparation for applying to a skin, the fiber layer being adjusted such that the basis weight of the fiber assembly and the permittivity of the liquid preparation are in a predetermined range, having controlled vapor permeability.

A coating film for human skin, the coating film comprising a fiber layer, wherein the fiber layer comprises: a fiber assembly in which fiber of a water-insoluble polymer with a fiber diameter of 50 nm or more and less than 10,000 nm is deposited; and a liquid preparation X present between fibers and on a surface of fibers in the fiber assembly, the fiber assembly has a basis weight Q of 0.08 to 1.0 mg/cm.sup.2, and the liquid preparation X has a basis weight P of 0.5 to 2.3 mg/cm.sup.2 and a relative permittivity of 1.0 to 27, and comprises a component (a): oil agent in a liquid state at 20° C. and has a relative permittivity of 0.5 to 20, and a component (b): polyol in a liquid state at 20° C. in which the content of the component (b) in the liquid preparation X is 50 mass % or less.

The inventive subject matter provides compositions and methods for transiently or permanently treating or managing an injury. Contemplated compositions are polymerizable in situ over short time periods, even in the presence of blood, without undue exothermic heat. Contemplated compositions may further comprise an anesthetic, an antiseptic, an adhesion promoter, and/or a vasoconstrictor.
