Ciplukan (Physalis angulata Linn) Bioactivity against Bleomycin-Induced Pulmonary Fibrosis in Mice by reducing Subpleural Fibrosis, KL-6 Level and Anti-Inflammatory properties

Résumé fourni par la source

Pulmonary fibrosis is a fatal lung disease with unknown pathogenesis and limited treatment options. Herbal medicine began to be developed as an antifibrosis drug for this disease. Ciplukan plant (Physalis angulata Linn.), is a wild plant that has been widely used for generations as traditional Indonesian medicine for various diseases; but has never been studied as an antifibrosis. This study aimed to determine Ciplukan herb ethanol extract (CPL) bioactivity as antifibrosis in pulmonary fibrosis disorders in experimental mice model induced by bleomycin. A total of 35 male mice and 35 female mice of the ddy strain was divided into 7 groups respectively with 1 normal control group and 6 experimental animal models of pulmonary fibrosis induced by bleomycin groups. For the pulmonary fibrosis model, bleomycin (BLM) was injected subcutaneously 8 times with a frequency of twice a week for 4 weeks. Furthermore, the mice were given CPL orally starting at week 6 of treatment with 2 different doses, 1.95mg (CPL-1) and 3.9mg (CPL) every day for 4 weeks. Pulmonary fibrosis histopathology was analyzed using HE and MT staining methods. Serum IL-6, KL-6, and TGF-β1 levels determination was carried out using the ELISA method. The administration of CPL significantly reduced the fibrosis score from 2.80±1.095 to 1.67±0.577µm (p=0.026). The CPL also showed anti-inflammatory activity by reducing IL-6 levels from 1916.20±594.27 to 16.81±17.07pg/mL (p=0.003); TGF-β1 levels from 51.25±2.25 to 22.48±0.93ng/mL (p=0.021); and KL-6 levels from 28.09±2.25 to 13.99±0.93ng/mL (p=0.000). CPL was proven to have pulmonary antifibrotic activity in experimental mice model. The pulmonary antifibrotic effect was evidenced by a decrease in pulmonary fibrosis scores also a decrease in KL-6 levels, IL-6 levels, and TGF-β1. The administration of CPL-1 and CPL-2 can provide recovery of pulmonary fibrosis induced by bleomycin.
