    Abstract:
    OBJECTIVE: To investigate the effects of angelicanaphtha on proliferation, cell cycle, apoptosis, and collagen synthesis of human umbilical vein endothelial cells (HUVEC). METHODS: HUVEC was cultured and passaged in Dulbecco's modified Eagle's medium (DMEM) and treated with angelicanaphtha 1 mg/ L, 4 mg/L, and 16 mg/L at 1, 3, 5, and 7 day respectively. The proliferation was measured with MTT method. The cell cycle and apoptosis were analyzed with flow cytometry and collagen synthesis was determined with radioimmunoassay. RESULTS: The proliferation of the HUVEC was accelerated by angelicanaphtha < or =4 mg/L and inhibited by angelicanaphtha at 16 mg/L (P < 0.05). Lower concentration (< or = 4 mg/L) of Angelicanaphtha decreased cells in G0/G1 phase and increased significantly cells in S phase and inhibited the apoptosis (P < 0.05). However, angelicanaphtha at 16 mg/L increased cells in G0/G1 phase and decreased cells in S phase and induced the apoptosis (P < 0.05). The collagen synthesis of HUVEC was inhibited by angelicanaphtha in concentration-dependent manner (P < 0.05 or 0.01). CONCLUSION: The proliferation effects of angelicanaphtha on HUVEC had dualistic regulation of increase by lower-concentration and inhibition by higher-concentration. Collagen synthesis of HUVEC was inhibited by angelicanaphtha in concentration-dependent manner.
