Abstract: The present invention relates generally to the field of respiratory therapeutics, and in particular to the treatment of disorders of the lung matrix caused by damage to the elastic fibers of the lung matrix. More specifically, methods and materials are disclosed for the delivery to the lungs of polysaccharides, derivatives thereof and/or drug conjugates, used in the treatment and/or prevention of pulmonary disorders.

Abstract: The subject invention is directed to the prevention of elastic fiber injury by administering HA or any other polysaccharide or carbohydrate moiety that binds to and coats elastic fibers, thereby preventing enzymes, oxidants, or other injurious agents from contacting and damaging these fibers. The method may be used to prevent elastic fiber damage which occurs to the skin and blood vessels as a consequence of aging, to the uterus during pregnancy, and in diseases such as pulmonary emphysema, aortic aneurysm, and joint disease. The treatment is intended for humans and a variety of other mammals. The polysaccharide or carbohydrate moiety may be administered orally, cutaneously, subcutaneously, intravenously, intratracheally, or by any other route deemed efficacious. It may be administered alone or in combination with another polysaccharide or carbohydrate moiety, with or without a carrier such as saline solution, DMSO, alcohol or water.

Abstract: The subject invention is directed to the treatment of respiratory disorders by intratracheal administration of an effective amount of hyaluronic acid. Respiratory disorders include emphysema, chronic bronchitis, asthma, pulmonary edema, acute respiratory distress syndrome, bronchopulmonary dysplasia, pulmonary fibrosis, and pulmonary atelectasis. The treatment is intended for a variety of mammals, such as premature neonates to adult humans. Administration of hyaluronic acid may be performed by aerosol, which can be generated by a nebulizer, or by instillation. The hyaluronic acid may be administered alone, or with a carrier such as saline solution, DMSO, an alcohol or water. It may be isolated from a natural source such as a bovine or rooster. The effective daily amount of hyaluronic acid is from about 10 .mu.g/kg to about 1 mg/kg of body weight.
