Abstract:
The preliminary results of inactivation of model parvovirus M13Mp 18 in plasma by long-waveUVA irradiation combined with psoralen derivatives were described.At 8-MOP concetration of300?g/ml plasma and UVA intensity of 11.5mW/cm~2,the UVA irradiation for 30～120 min couldresult in virus inactivation of 10~(5～9) infectious dose/ml.Quenchers were used to reduce the damage ofUVA to proteins in order to improve the clotting factor recovery after irradiation.2mmol/Lglutathione,or 2mmol/L glutathione with 2 mmol/L mannitol could significantly improve the Frecovery after irradiation.
