Bayliss myogenic response in the isolated ductus arteriosus of guinea-pig and rabbit fetuses. 1978

V Smiesko, and M Kriska, and V Kovalcik

Isolated ductus arteriosus responds by marked constriction to increases in perfusion pressure. If, however, these increases exceed 90 mm Hg-130 mm Hg, the vessel suddenly dilates and its responsiveness becomes depressed. The importance of these findings in postnatal closure of ductus arteriosus is discussed.
