“…IudR, which has been shown to inhibit HSV in vitro (116,124,200,207,231), has yielded promising results in the treatment of herpes encephalitis (18,44,160,165,254) and herpetic keratitis (5,53,61,261). Similar results have been obtained with ara-c both in vitro (78,193,207) and in the treatment of a variety of herpetic eruptions (109) including oral lesions (158) and herpes encephalitis (73,86,257). Of the two drugs, ara-c is slightly favored, because of the ease of administration and its reduced toxicity to the host (73, 109), even though it may synergistically act with HSV to effectuate increased chromosomal damage (192,193).…”
