摘要:
Aspects of the invention provide methods for treatment of a disease associated with elevated iNOS including autoimmune, chronic inflammatory, neurodegenerative, or cardiovascular diseases. In particular, aspects of the invention relate to the use of a therapeutic formulation comprising a galacto-rhamnogalacturonate for the treatment of a disease associated with elevated iNOS including autoimmune, chronic inflammatory, neurodegenerative, or cardiovascular diseases.
摘要:
A therapeutic composition for treatment of a body tissue which includes an aqueous solution of a cross-linked polymer being capable of: (i) maintaining a liquid state in storage at room temperature for at least 24 hours; and (ii) assuming a gel state following deposition within the body tissue. The therapeutic composition can be effectively administered into a damaged body tissue via injection or catheterization, thereby treating the damaged body tissue.
摘要:
The present invention relates to an injection solution for intra-articular administration for treating arthritic disorders comprising a cross-linked hyaluronic acid derivative wherein part of functional groups of a hyaluronic acid are cross-linked with a cross-linking group to the extent of 0.6 to 15% of cross-linking extent as an active ingredient in an amount having a long-lasting analgesic effect and a pharmaceutically acceptable carrier, and an analgesic composition for suppressing a cartilage degeneration caused by arthritic disorders or a composition for suppressing a cartilage degeneration or an inflammation of synovium caused by arthritic disorders each comprising the cross-linked hyaluronic acid derivative and a pharmaceutically acceptable carrier.
摘要:
The present invention provides an ionically cross-linkable alginate-grafted hyaluronate compound containing alginate and hyaluronate, the alginate and the hyaluronate forming a covalent linkage. The use of the compound can easily provide a cross-linked hyaluronate by adding a divalent cation without using a chemical cross-linking agent. The present invention also provides a method for cell transplantation that includes preparing a composition comprising the compound of claim 1 and cells for transplantation, and administering to a subject in need thereof the composition.
摘要:
Uses of depolymerized hyaluronan (e.g., prepared by sonicating high molecular weight hyaluronan such as naturally-occurring hyaluronan) or anti-Hyal-2 antibody in cancer treatment. Also described herein are methods for preparing depolymerized and crosslinked hyaluronan by sonication and the hyaluronan composition thus obtained.

摘要:
The present invention relates to protein biocoacervates and biomaterials and the methods of making and using protein biocoacervates and biomaterials. More specifically the present invention relates to protein biocoacervates and biomaterials that may be utilized for various medical applications including, but not limited to, drug delivery devices for the controlled release of pharmacologically active agents, coated medical devices (e.g. stents, valves . . . ), vessels, tubular grafts, vascular grafts, wound healing devices including protein suture biomaterials and biomeshes, dental plugs and implants, skin/bone/tissue grafts, tissue fillers, protein biomaterial adhesion prevention barriers, cell scaffolding and other biocompatible biocoacervate or biomaterial devices.
摘要:
Hydrogels formed from hyaluronic acid, a nanoclay and gelatin-type A. The hyaluronic acid is preferably dissolved in a cell culture medium containing amino acids, salts, glucose, vitamins and an antibiotic to form a hyaluronic acid solution. The gelatin-type A has a weight/volume of from about 0.02% to 0.08%. The nanoclay is exfoliated in deionized water and preferably includes SiO2, MgO, Na2O and Li2O.
摘要:
An injectable aqueous composition of hyaluronic acid or one of the salts thereof, one or more polyol(s) and lidocaine is used for cosmetic purposes or for therapeutic purposes. It has improved viscoelastic rheological properties and long in vivo persistence. The polyol is chosen, for example, from glycerol, sorbitol, propylene glycol, mannitol, erythritol, xylitol, maltitol and lactitol. The particular properties are obtained by heat sterilising the mixture.
