Pretreatment of human fibroblast cultures with human leukocyte interferon (HIF, 1,000 IU/ml) resulted in a 24-h delay of virus replication after infection with vaccinia virus and herpes simplex virus type 1 and type 2. Additional HIF treatment 24 h after infection effectively lowered the maximum yield of viral infectivity. Equal results were obtained in simian cells with 3,000 IU of HIF per ml....

Metabolites isolated from marine inverteimmunodeficiency virus (1, 5, 6, 7), were tested on a new in vitro bioassay using the dengue virus 1. Only brates, callipeltin A 1, crambescidin 2, ptilomycalin A 3, gymnochrome D and isogymnochrome D isolated from celeromycalin 4, gymnochrome B 5, gymnochrome D 6 the living fossil crinoid Gymnocrinus richeri are highly and isogymnochrome D 7 previously s...
