The study aimed to determine efficacy and mechanisms of β-Amyrin on pulmonary fibrosis. Use bleomycin (BLM) to induce the marine model of pulmonary fibrosis. β-Amyrin (20, 40, 80 mg/kg) was once treated via intragastrical administration for five consecutive days when after BLM stimulation. HE/Masson staining, hydroxyproline (HYP) content, Arterial blood gas analysis (BGA), inflammatory cytokines and oxidative stress factors were performed in this study. The lung gas-exchange function was significantly improved after being treated β-Amyrin with different concentrations, while IL-6, IL-1β, TNF-α and MCP-1 levels were decreased. And the increased fibrotic lesion in lung was also determined after treatment of β-Amyrin. Additionally, reduced MDA level and increase levels of GPX, SOD and GSH were also demonstrated using β-Amyrin in BLM-induced mice in a dose-dependent manner. In conclusions, our study determined that β-Amyrin has a potent efficacy in protecting against BLM-induced pulmonary fibrosis via suppressing inflammatory response and oxidative stress.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D009828	Oleanolic Acid	A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin.	Oleanol,Hederins,Oleanane Triterpenes,Triterpenes, Oleanane
D011658	Pulmonary Fibrosis	A process in which normal lung tissues are progressively replaced by FIBROBLASTS and COLLAGEN causing an irreversible loss of the ability to transfer oxygen into the bloodstream via PULMONARY ALVEOLI. Patients show progressive DYSPNEA finally resulting in death.
