Mesalamine, olsalazine, and balsalazide do not contain sulfa. So they may be used to treat mild to moderate ulcerative colitis if you cannot take sulfasalazine. Mesalamine enemas are effective in treating symptoms of mild to moderate distal (left-sided) ulcerative colitis and in maintaining remission.
Medical Definition of ankylosis. plural. ankyloses. \-ËsÄz\play. : stiffness or fixation of a joint by disease or surgery.
When the structures outside the joint are affected, the term false ankylosis has been used in contradistinction to true ankylosis, in which the disease is within the joint. When inflammation has caused the joint-ends of the bones to be fused together, the ankylosis is termed osseous or complete and is an instance of synostosis.
