    摘要: A hemostatic material and a method of treating a bleeding wound of a human or an animal include a hemostatic powder for application to the wound. The hemostatic powder comprises a first part consisting of a native chitosan base and a second part consisting of a chitosan salt, where the first and the second parts form the main component of the hemostatic powder, or at least 50% of a total weight of the hemostatic powder, and the second part forms a layer that at least partially coats the first part. The hemostatic powder may be provided in a hemostatic spray formulation that comprises a mixture of the hemostatic powder dispersed in a liquefied gas for release from a cannister onto the wound. A treatment method involves applying the hemostatic spray formulation directly to the wound. Other embodiments are also disclosed.

    摘要: A chelate compound wherein a chelate-forming moiety is attached to a base compound having an amino group and at least a part of the amino group is in the form of a halide salt. A specific example of the halide salt is hydrochloride. As the base compound, a chitosan having a glucosamine skeleton is preferred. Also, chitosan beads are usable. The chelate compound is produced by reacting the base compound having an amino group with an aldehyde group of an aromatic cyclic compound, aromatic cyclic compound having at least a functional group capable of forming a chelate and the aldehyde group, to form a Schiff base, reducing the Schiff base with a reducing agent and then treating with a hydrohalogenic acid (hydrochloric acid).
