Abstract

Particulate matter 2.5 (PM2.5) is a growing concern worldwide due to its association with respiratory diseases, including chronic obstructive pulmonary disease (COPD). Stemonine, a traditional Chinese herb, has been demonstrated to exhibit anti‑inflammatory and antioxidant properties, making it a potential drug for the treatment of respiratory diseases. The therapeutic effects of stemonine on mice with PM2.5‑induced COPD were investigated in the present study. Kunming mice were randomly divided into the following five groups (n=10/group): Control, model, low‑dose stemonine, moderate‑dose stemonine and high‑dose stemonine. The model mice received an intranasal instillation of PM2.5 suspension (40 mg/kg). The levels of specific enzymes, markers of oxidative stress, and the inflammatory cytokines tumor necrosis factor (TNF)‑α and interleukin (IL)‑6 were measured in the bronchoalveolar lavage fluid of the mice using ELISA kits. Hematoxylin and eosin staining was performed to determine inflammatory changes to the lung tissue. It was demonstrated that stemonine could significantly alleviate lung injury by decreasing the levels of enzymes and cytokines associated with inflammation and oxidative stress in a dose‑dependent manner. In addition, stemonine dose‑dependently increased the amount of superoxide dismutase. These results suggest that stemonine reduces lung inflammation in mice with PM2.5‑induced COPD, providing a novel approach for the treatment of PM2.5‑induced respiratory diseases.
