Ribonuclease is a highly active inhibitor of vaccinia virus multiplication in vitro in the chorioallantoic membrane removed from embryonated chicken eggs. It is also a highly active inhibitor of pock formation by vaccinia and herpes simplex viruses on the chorioallantoic membrane in vivo. Marked inhibitory effects were obtained with 12.5 microg. of RNase. However, complete inhibition was not ob...

Oncolytic viral therapy, which makes use of replication-competent lytic viruses, has emerged as a promising modality to treat malignancies. It has shown meaningful outcomes in both solid tumor and hematologic malignancies. Advancements during the last decade, mainly genetic engineering of oncolytic viruses have resulted in improved specificity and efficacy of oncolytic viruses in cancer therape...

INTRODUCTION Cytomegalovirus and herpes simplex virus are associated with congenital or perinatal infection, causing potential damage to the newborn. OBJECTIVES Determine the prevalence of active or latent infection by cytomegalovirus and herpes simplex virus in a population of mothers, congenital infection by these agents in their infants, and association between prevalence of virus infectio...

Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

Table 1 lists possible interactions of viruses in oncogenesis and emphasizes the role of human pathogenic viruses. The majority of tumor viruses known today insert their genetic material into the host cell nucleus, where it persists. The expression of at least one viral function appears to be a prerequisite for the maintenance of the transformed state. An interesting difference in interactions ...

INTRODUCTION We present a case of an unusual clinical manifestation of Guillain-Barre syndrome following a pre-existing herpes virus infection. Although there have been several reports describing the co-existence of herpes virus infection and Guillain-Barre syndrome, we undertook a more in-depth study of the cross-reactivity between herpes viruses and recommend a follow-up study based on serolo...

many must be the result of using impure systems and of secondary effects or else they are the product of a multiplicity of phenomena with similar end results. Dr. Vilcek is a splitter; he gives the impression that no unifying principle exists in the interferon system, but that there are several physically diverse interferons produced by the same cell and that cells may be induced to produce the...

The risks of transmitting viral infection by blood and plasma-derived products have long been known and still remain an area of concern. In this study, in the process of purifying human factor VII from prothrombin complex, SID treatment using tri-n-butyl phosphate and Tween 80 was employed and its capability and efficacy was studied. The results indicated that the process did not affect th...
