Method for increasing placental blood flow

摘要

A method for increasing the placental blood flow, which comprises administering a human-originated antithrombin-III. The human- originated antithrombin-III increases the placental blood flow in mammals and particularly improves intrauterine growth retardation caused by a decreased blood flow. The method is highly safe to the mother and fetus, since it uses human-originated AT-III as an active ingredient, thereby enabling effective and safe treatment of intrauterine growth retardation (IUGR) and the like.
