The in vitro susceptibility of varicella zoster (VZ) isolates to adenine arabinoside (ara-A) and hypoxanthine arabinoside (ara-Hx) was determined in human skin fibroblasts. Using a system in which deamination was inhibited, and using a modified plaque reduction method, the antiviral activities of ara-A and ara-Hx were separated. The plaque inhibitory concentration of ara-A for all VZ isolates tested was 1 to 2 mug/ml and 80 to 100 mug/ml for ara-Hx. A comparison of antiviral activity based upon total plaque suppression gave a rate of 40 to 50:1, in favor of ara-A.
在人皮肤成纤维细胞中测定了水痘带状疱疹(VZ)分离株对阿糖腺苷(ara - A)和阿糖次黄嘌呤(ara - Hx)的体外敏感性。使用一种抑制脱氨作用的系统,并采用改良的蚀斑减少法,分离出了ara - A和ara - Hx的抗病毒活性。所测试的所有VZ分离株中,ara - A的蚀斑抑制浓度为1至2微克/毫升,ara - Hx为80至100微克/毫升。基于总蚀斑抑制的抗病毒活性比较得出比率为40至50:1,有利于ara - A。
