摘要 目的:探讨重组似病毒方法应用于评价抗病毒药物的可行性。方法:采用 pSG3△env/TZM-bl 系统,制备假病毒毒种,在不同细胞,不同重组假病毒接种量的条件下,血用重组假病毒法测定 AZT 的抗病毒效果,以此选择最适的细胞接种量、病毒接种量,砰价检测方法的重复性,用建立的假病毒检测法测定 AZT、3TC、d4T、ddI 的抗病毒效果。结果:细胞接种量对检测结果有一定的影响,最适细胞接种量为每孔10~4个细胞;重组假病毒接种量对检测结果没有明显的羞异;重复性检测结果显示,该方法的 RSD 为11.52%;用该法检测 AZT、3TC、d4T、ddI 的50%抑制浓度(IC_(50)值)分别为0.0074 μmol·L^(-1)、0.5312 μmol·L^(-1)、0.0868 μmol·L^(-1)、3.4364 μmol·L^(-1)。结论:重组假病毒法可用于评价抗 HIV-1约物,具有快速、简便的优点。 Objective :To evaluate the feasibility of recombinant virus assay on evaluating anti - HIV - 1 drug susceptibility. Methods: Recombinant virus stocks were prepared using pSG3 Δenv/TZM- bl system; Innoculation numbers of cell and titre of recombinant virus were selected based on AZT susceptibility by recombinant virus assay. The reproducibility of this assay was evaluated. Susceptibility of anti - HIV - 1 drug including AZT,3TC, d4T and ddI was measured by recombinant virus assay at optimal innoculation number of cell and titre of recombinant virus. Results : Innoculation number of cell affects the results of drug susceptibility and the optimal innoculation number of cell was 10^4/well;Innoculation titre of recombinant virus has no significant effect on the results of drug susceptibility. The recombinant virus assay showed good reproducibility with RSD of 11.52%. IC50 of AZT,3TC, d4T and ddI measured by the recombinant virus assay was 0. 0074 μmol·L^-1 ,0. 5312 μmol·L^-1 ,0. 0868 μmol·L^-1and 3. 4364 μmol·L^-1,respectively. Conclusion:Recombinant virus assay can be used to analyze anti - HIV - 1 drug susceptibility quickly and effectively.
