A joint cavity injection preparation is provided. The active ingredient of the joint cavity injection preparation is deacetylated xanthan gum (XG). The deacetylated XG has a molecular weight of 500,000 to 20,000,000. The joint cavity injection preparation is prepared from deacetylated xanthan gum (XG), which has higher biocompatibility and safe wide-dosage range than existing joint cavity injection preparations prepared from XG.

Provided herein is a method of treating an infectious disease by administering to a patient a pharmaceutical formulation dissolved in aqueous medium having at least one free fatty acid, or a derivative and/or a pharmaceutically acceptable salt of the same, where the free fatty acid has from 6 to 16 carbon atoms, at least one carboxylic acid or a pharmaceutically acceptable salt of the same, and/or at least one carbohydrate or a pharmaceutically acceptable salt of the same. The carbohydrate may be selected from a hydrogenated carbohydrate, a monosaccharide, a disaccharide, a polysaccharide or a combination of the same. The antimicrobial composition provides enhanced anti-adhesion and/or disinfecting properties. The composition may be formulated into a drink, gel or spray, suitable for treating or preventing the first stage in pathogenesis.

The present disclosure provides a composition for submucosal injection including a divalent cation and an oligosaccharide obtained by exposing powdered polysaccharides to irradiation, heat, ultrasound, or ultraviolet radiation. The composition may be provided as a single solution; or the divalent cation and the oligosaccharide may be separately packaged, with the divalent cation being provided in solution form and the oligosaccharide being provided in powder form. The divalent cation may be 0.1-0.5% w/v of Ca.sup.2+, Mg.sup.2+, Fe.sup.2+, Cu.sup.2+, Ba.sup.2+, Zn.sup.2+, or any combination thereof. The oligosaccharide may be 0.5-2% w/v of degraded sodium alginate, degraded xanthan gum, degraded dextran, degraded welan gum, degraded gellan gum, degraded diutan gum, or any combination thereof. When the divalent cation is in contact with the oligosaccharide, viscosity of the composition is greater than 1000 cP, and injection pressure of the composition falls within a range of 2.5-4 kgf.

The present invention relates to a method for dynamic filtration of a cross-linked biopolymer-based hydrogel to remove unwanted molecules from the gel. In particular, the invention relates to dynamic filtration of a hyaluronic acid hydrogel using a dynamic filtration construction with rotating and semipermeable filter discs.

A treatment for obesity can include: providing a superabsorbent material that includes a porous network structure formed from a mixture of a plurality of water soluble polysaccharides that are not chemically crosslinked together; and administering the superabsorbent material to a subject in an effective amount to provide a treatment for obesity in the subject. The treatment can include at least one of: reducing weight of the subject; reducing rate of weight gain in the subject; or increasing rate of weight loss in the subject. The treatment of obesity can include at least one of: reducing caloric intake into the subject; reducing caloric absorption by the gut of the subject; absorbing caloric material from the gut of the subject into the superabsorbent material; or increasing transfer of caloric material from bloodstream into gut.
