We have investigated the possible interaction of Japanese Kampo medicine; Shosaiko-to with Epstein-Barr virus (EBV) induction by TPA (12-O-tetra-decanoyl-phorbol-13-acetate) in EBV-genome harboring cells. The effect of ether extract of Shosaiko-to was also studied on the induction of EBV by superinfection with EBV from P3HR-1 cells (P3H-EBV). Concomitant treatment of EBV-latently-infected cells (Raji and A2L/AH) with TPA and ether extract resulted in effective inhibition of EBV-antigen induction. However, in the experiments to test the influence of ether extract on EBV induction by superinfecting Raji cells with P3H-EBV, ether extract did not affect the percentage of EBV-antigen-positive cells. These data indicate that Shosaiko-to is effective to inhibit antigen synthesis induced by chemical promoters without affecting EBV-antigen induction after superinfection.
我们研究了日本汉方药物小柴胡汤与12 - O - 十四酰佛波醇 - 13 - 乙酸酯(TPA)在携带EB病毒基因组的细胞中诱导EB病毒(EBV)之间可能存在的相互作用。还研究了小柴胡汤乙醚提取物对P3HR - 1细胞来源的EB病毒(P3H - EBV)超感染诱导EBV的影响。用TPA和乙醚提取物同时处理EB病毒潜伏感染细胞(Raji和A2L/AH)可有效抑制EB病毒抗原的诱导。然而,在测试乙醚提取物对P3H - EBV超感染Raji细胞诱导EBV影响的实验中,乙醚提取物并未影响EB病毒抗原阳性细胞的百分比。这些数据表明,小柴胡汤可有效抑制化学启动子诱导的抗原合成,而不影响超感染后EB病毒抗原的诱导。
