摘要

Treatment with psoralens and ultraviolet-A (UVA) irradiation have been found to be effective for virus sterilization of platelet concentrates (PCs). We report here a virus inactivation method using a combination of psoralen derivative 4' -aminomethyl-4,5', 8-trimethylpsoralen (AMT) and UVA irradiation (AMT/UVA). Further, we also investigated the effect of rutin, a radical scavenger, on the inactivation of vesicular stomatitis virus (VSV) as a model virus administered in PCs and platelet functions were investigated.Spiked VSV (about Slogio) in PCs was inactivated by a combination of AMT (50mu,g/ml) and 5.2 J/cm2 UVA irradiation in the absence of rutin. To obtain equivalent levels of VSV kill in the presence of 0.35 mM rutin, treatment with 13.0 J/cm~2 of UVA irradiation with AMT was performed.When PCs were treated under each condition in which 5logio VSV was inactivated by AMT/ UVA with or without rutin, platelet aggregation function was maintained for more than 80%of untreated platelets. These findings indicate that the presence of rutin during AMT/UVA treatment conferred no beneficial effect. In addition, overnight storage of PCs with AMT induced 40%loss of platelet aggregation in response to 10muM ADP. The findings suggest that UVA irradiation is required immediately after the addition of AMT.
