The present disclosure provides a hydrogel tablet for relieving alcoholism and protecting the liver as well as the preparation process and application thereof. The present disclosure firstly provides a composition with the effects of relieving alcoholism and protecting the liver, which comprises the following components on the basis of weight parts: 20˜40 parts of chitosan, 25˜55 parts of sodium alginate, 3˜20 parts of gelatin, 1˜10 parts of calcium carbonate and 0.05˜0.5 parts of gallic acid. Based on this composition, the present disclosure further provides a hydrogel tablet for relieving alcoholism and protecting the liver. In the present disclosure, chitosan, sodium alginate and calcium carbonate are compounded at an appropriate proportion to form powder particles of chitosan/sodium alginate (shell)-calcium carbonate (core), into which are additionally added gelatin and gallic acid to get a product that is the hydrogel tablet.

A composite material for rapid blood clotting and its preparation method are provided. The composite material includes the following raw materials in parts by weight: 8˜20 parts of chitosan, 7˜14 parts of salicylaldehyde, 8˜16 parts of 2-aminoisonicotinic acid, 1.5˜3.5 parts of ferrous sulfate, 3˜5 parts of dopa, and 10˜15 parts of disodium hydrogen phosphate. The composite material for rapid blood clotting has good stability, high biological safety, significant effects on blood clotting, simple process, and easy industrial production.

Composite material for rapid blood clotting and preparation method thereof

A wound-healing and hemostatic sponge of squid ink polysaccharide/chitosan, a preparation method and use thereof are provided. The sponge comprises squid ink polysaccharide and chitosan as carriers and calcium chloride as an initiator for blood coagulation, and the wound-healing and hemostatic sponge of squid ink polysaccharide/chitosan is achieved via a lyophilization technology. Particularly, the preparation method comprises slowly adding a squid ink polysaccharide solution to a chitosan solution to form a uniformly mixed solution, adding a calcium chloride solution to the uniformly mixed solution, forming a gel followed by the gel being frozen and then lyophilized, and achieving the product. The wound-healing and hemostatic sponge has a good absorbing-errhysis effect, a good pro-coagulant effect, fast hemostasis and a complete hemostatic effect, without secondary re-hemorrhage. Moreover, the wound-healing and hemostatic sponge can promote wound healing, re-epithelialization and repair of epidermis and dermis, with strong wound-healing ability, good biocompatibility, weak toxic side effects and irritation, belonging to a novel wound-healing and hemostatic material. Moreover, the preparation method is reliable, fast, and low cost.
