title: Biochemical changes in human cervical connective tissue after local application of prostaglandin E2.
abstract: Intracervical application of prostaglandin E2 in the late first trimester induces (1) softening of the cervix tissue; (2) increase in sulfated glycosaminoglycans (18 +/- 12%, mean +/- SEM); (3) no change in hyaluronic acid and water; (4) decrease in pepsin-extractable collagen, and (5) apparent decrease in collagenase. A high activity of collagenase in combination with a replacement of collagen with sulfated glycosaminoglycans may be of importance for the ripening process.
