EFFECT OF TEMPORARY TRACHEAL OCCLUSION ON THE ENDOTHELIN SYSTEM IN EXPERIMENTAL CASES OF DIAPHRAGMATIC HERNIA

Previously, the authors have shown that tracheal occlusion (TO) partially reverses the onset of congenital diaphragmatic hernia (CDH)-induced pulmonary hypertension (PH) and abnormal pulmonary vascular development whereas release of the occlusion (TR) abolishes these clinical benefits. As a consequence of their mitogenic and vasoactive properties, the authors hypothesize that the expression of endothelin (ET)-1 and ET receptor (ETA) genes is …
