Abstract: Xerostomia is treated with a sulfur-containing antioxidant, such as N-acetylcysteine. Delivery compositions including polyoxyalkylene block copolymers may be used, which may be formulated to exhibit reverse-thermal viscosity behavior.

Abstract: The present invention provides an immunogen composition and methods for using the same for the development of immunity. In one method, the immunogen composition is administered to prepare a person for a later booster administration. This immunogen composition includes an antigen and a polyoxyalkylene block copolymer. In another method the booster administration is given to a person previously prepared for the booster through prior administration of the immunogen composition. Another method includes multiple administrations, with a later administration boosting the immune response from a prior administration.

Abstract: This present invention provides a therapeutic composition for use in the treatment of mucositis and a method for using such a therapeutic composition. The therapeutic composition includes a pharmaceutical substance effective for treating mucositis formulated with a biocompatible polymer, such as a biocompatible reverse-thermal gelation polymer.

Abstract: A method for treatment of proctitis is disclosed in which a therapeutic composition is introduced into the rectum to contact a mucosal surface within the rectum. The pharmaceutical composition comprises a reverse-thermal gelation polyoxyalkylene block copolymer, a pharmaceutical substance and a pharmaceutical substance selected from the group consisting of glutathione and a precursor for glutathione biosynthesis.

Abstract: A method for treatment of esophagitis is disclosed in which a therapeutic composition is introduced into the esophagus to contact a mucosal surface within the esophagus. The pharmaceutical composition comprises a reverse-thermal gelation polyoxyalkylene block copolymer, a pharmaceutical substance and a pharmaceutical substance selected from the group consisting of glutathione and a precursor for glutathione biosynthesis.
