Amelioration of bleomycin induced pulmonary fibrosis by administration of Salvianolic acid B in mice.

Pulmonary fibrosis is the end‑stage manifestation of wide range of respiratory diseases and during pulmonary fibrosis, pulmonary inflammation and epithelial‑mesenchymal transition (EMT) play important roles. Salvianolic acid B (SAB) from the herb Salviae miltiorrhiza has been reported to possess an excellent anti‑inflammatory, antifibrotic and antioxidant activity. The present study aimed to investigate the ameliorative effect of SAB on bleomycin induced pulmonary fibrosis in mice.
