A means and method for treating pulmonary fibrosis in animals is described. The
compositions include surfactant lipids in a pharmaceutically acceptable carrier.
Surfactant lipids have been found to suppress the synergistic effect of bleomycin
and SP-A in enhancing proinflammatory cytokine production. Surfactant lipids are
also effective in the prevention and treatment of pulmonary fibrosis resulting
from exposure to inflammatory agents affecting cytokine production.
