Objective: To investigate the effect of ultra-filtration extraction from Angelicae Sinensis Radix and Hedysari Radix on the cell proliferation and collagen deposition of myocardial fibroblasts induced by radiation. Method: Rat myocardial fibroblasts were separated and cultured by cell adhesion. The cell proliferation was determined by thiazolyl blue tetrazolium bromide (MTT) method
and the collagen- Ⅰ (COL- Ⅰ) of secretion was determined by enzyme-linked immuno sorbent assay (ELISA) method after ultra-filtration extraction from Angelicae Sinensis Radix and Hedysari Radix or radiation to myocardial fibroblasts. The changes of reactive oxygen species (ROS) were determined by flow cytometry with indicator 2'
7'-dichloride fluorescent yellow double acetate (DCFH-DA) staining. The mRNA expressions of COL- Ⅰ and transforming growth factor-beta (TGF-β) were determined by Real-time polymerase chain reaction (PCR)
and the expressions of relative proteins were determined by Western blot. Result: The rising cellular ROS promoted cell proliferation and collagen deposition of myocardial fibroblasts induced by low-dose radiation (0.5 Gy)
which however was inhibited through ultra-filtration extraction from Angelicae Sinensis Radix and Hedysari Radix by promoting nuclear translocation of nuclear factor E2 related factor 2 (Nrf2) and eliminating ROS. The mRNA expressions of COL- Ⅰ and TGF-β were both inhibited by ultra-filtration extraction from Angelicae Sinensis Radix and Hedysari Radix. Conclusion: Ultra-filtration extraction from Angelicae Sinensis Radix and Hedysari Radix could inhibit the cell proliferation and collagen deposition of myocardial fibroblasts induced by low-dose radiation.
