  • Publication number: 20170340774
    Abstract: The present invention relates to a polyethylene glycol hydrogel injection, and, more particularly, to an injection to be administered into a joint (a synovial joint cavity) for the improvement of symptoms of arthritis by containing two separate buffer solutions, wherein a solution (1) contains a polyethylene glycol derivative with an electrophilic functional group and a buffer of pH 3.5 to 6, and a solution (2) contains a polyethylene glycol derivative with a nucleophilic functional group, hyaluronic acid, and a buffer of pH 7.5 to 11. The injection of the present invention is highly biocompatible and long-lasting in the joint, showing the efficacy of pain relief, cartilage protection, and inhibition of inflammation, thus offering the effective prevention and treatment of arthritis.

  • Publication number: 20140155457
    Abstract: Provided is a method of relieving, improving, preventing or treating xerostomia including applying an oral cavity composition including a polyethylene glycol (PEG) derivative whose reactor is modified to form a covalent bond with an epithelial cell of the oral cavity. An oral moisturizing effect and moisture persistency are increased and the method is effective against xerostomia due to aging or disease.
