Attenuation of pulmonary fibrosis in mice by aminophylline.


Cyclic nucleotides have been shown in vitro to regulate fibroblast proliferation and/or collagen production. We have reported previously that propranolol, which decreases the cAMP/cGMP ratio, potentiates the amount of fibrosis produced in a damaged lung. The purpose of this study was to determine if elevations in the cAMP/cGMP ratio may attenuate collagen… (More)
