Altered in vitro uptake of E-5-2-125iodovinyl-2'-deoxyuridine following administration of the antineoplastic agent etoposide.
The semi-synthetic epipodophyllotoxin derivative, etoposide (VP-16-213), has been shown to inhibit nucleoside uptake in mammalian cells. The present study examined whether etoposide (or the solvent in which it is usually supplied) affected the uptake of the radioiodinated antiviral nucleoside analogue E-5-2-125Iodovinyl-2'-deoxyuridine (125IVDU) by HSV1-infected cells (human herpesvirus 1; herpesvirus simplex type 1). Etoposide was found to significantly reduce 125IVDU sequestration, although some of this effect could be attributed to the solvent. The results are discussed in relation to the use of etoposide in the development of a specific, scintigraphic brain imaging technique to enable early diagnosis of herpes encephalitis.

Effects of the anti-cancer agent etoposide on human herpesvirus 1 replication in vitro.
The anti-human herpesvirus type 1 (herpes simplex virus 1; HSV1) activity of etoposide (VP-16-213, a semi-synthetic derivative of epipodophyllotoxin) was investigated in vitro. Etoposide (but not the proprietary solvent in which the compound is usually formulated) demonstrated a significant antiviral action, probably through an effect on virus replication. Etoposide, at 3 micrograms/ml, induced a 50% reduction of HSV1-plaque formation in Vero cells. These findings are considered in the context of the use of etoposide in an in vivo procedure for the diagnosis of herpes encephalitis through virus-specific scintigraphic brain imaging.

Financial prep for Y2K.
The financial impact of Y2K will be significant and, in some cases, devastating. Careful analysis will help health care organizations prepare for all contingencies and set aside the necessary resources to become compliant.
