Abstract: Provided are a novel carboxymethyl cellulose (CMC) structure and a method for producing the same. The CMC structure of the present invention is useful as a medical material and particularly as an adhesion-preventing material, and has good biocompatibility and bioabsorbability and controllable periods of functioning and dissolving, or has both effects for preventing adhesions and wound healing. The CMC structure of the present invention is substantially composed of carboxymethyl celluloses, comprising an acid carboxymethyl cellulose and an alkaline metal carboxymethyl cellulose in a mixed state. The method of production of the present invention comprises subjecting the alkaline metal (or acid) carboxymethyl cellulose structure to an acid (or alkali) treatment, wherein the acid (or alkali) treatment is terminated before the alkaline metal (or acid) carboxymethyl cellulose is fully converted to the acid (or alkaline metal) carboxymethyl cellulose.

Abstract: Proposed is a novel soluble trauma-healing and hemostatic cellulose fiber capable of absorbing and readily dissolving hemorrhaging trauma loci when applied thereto and of promoting the hemostatic action of blood platelets and fibrin and cell adhesion to the trauma site. The coagulation protein-containing soluble trauma-healing and hemostatic cellulose fiber is produced in that after treatment of a natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, said fiber is carboxymethylated by reaction with a monochloro acetic acid solution for a given time (hours) in such a manner that the degree of partial substitution of the glucose units constituting the cellulose molecule (etherification degree) is 0.5-less than 1.0% and that, furthermore, the coagulation proteins fibrinogen, thrombin, and coagulation factor XIII are imparted by surface application or chemical bonding.

Abstract: A hemostatic agent, an agent for promoting cellular adhesion and an agent for curing an injury, each comprising an alkali or alkali earth metal salt of carboxylmethyl cellulose, and a pharmaceutically acceptable carrier are disclosed.

Abstract: A tissue sealant comprising thrombin, fibrinogen, and carboxylmethyl cellulose or an alkali metal or alkali earth metal salt thereof is disclosed. The tissue sealant of the present invention promotes a hemostasis of an injury to a skin surface or a viscus, a healing of an injury, an endothelium formation of a blood vessel, an adhesive activity of animal cells, such as endothelial cells or fibroblasts in vitro, and an adhesion and agglutination of platelets.
