The effect of a single and multiple doses of polyinosinic-polycytidylic acid (poly (I). poly(C) on lactic dehydrogenase virus viremia has been studied. A single injection of 200 mug of poly (I)-poly(C) given 6 h before infection with lactic dehydrogenase virus caused a temporary decrease in viremia of about 2.5 log10. Repeated injections of 100 mug of poly(I)-poly(C) every 24 h beginning at -24 h caused a temporary decrease in viremia of about 4.0 log 10. Therapeutic treatment with optimal dosage schedules (100 mug every 24 h) caused a reduction in viremia of 1.0 to 2.0 log10. This decrease lasted for at least 24 h after the treatment was stopped. Some possible reasons for the limited effectiveness of poly (I)-poly(C) in this system are discussed.
研究了单剂量和多剂量的聚肌苷酸-聚胞苷酸(聚(I)-聚(C))对乳酸脱氢酶病毒血症的影响。在感染乳酸脱氢酶病毒前6小时单次注射200微克聚(I)-聚(C),可使病毒血症暂时降低约2.5个对数10。从-24小时开始每24小时重复注射100微克聚(I)-聚(C),可使病毒血症暂时降低约4.0个对数10。采用最佳剂量方案(每24小时100微克)进行治疗,可使病毒血症降低1.0至2.0个对数10。这种降低在停止治疗后至少持续24小时。文中讨论了聚(I)-聚(C)在该系统中效果有限的一些可能原因。
