Abstract：
:Newborn rats received intraperitoneal injections of endothelin-1 in a daily dose of 5 x 10(-8)mol/kg 30 min after administration of NG-nitro-L-arginine methyl ester (9.3 x 10(-5)mol/kg intraperitoneally) from the 2nd to 6th day of life. NADPH diaphorase activity in epithelial and smooth muscle cells of the tracheobronchial system increased 24 h after the last treatment. In this period DNA synthesis underwent opposite changes, which included the inhibition of epithelial cell proliferation and stimulation of smooth muscle cell division. Intensification of free radical oxidation in the lung tissue was accompanied by inactivation of the antioxidant system.
