Objective: To explore the effect of Astragalus membranaceus (Ast) and Angelica sinensis (Ang) on focal adhesion kinase (FAK) expression and apoptosis of cultured vascular smooth muscle cells (VSMC). Methods: RT-PCR and Western blot were used to analyze the changes of FAK expression, Greiss reagent was used to measure concentration of nitric oxide (NO) in culture medium, bcl-2 and caspase-3 protein expressions and VSMC apoptosis were detected by flow cytometry. Results: Ast and Ang could significantly inhibi...
