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. It may be naturally occurring, chemically modified, or artificially synthesized. The effective daily amount of the polysaccharide or carbohydrate moiety is from about 0.1 mug/kg to about 1 mg/kg of body weight.
