9-[[2-Hydroxy-1-(hydroxymethyl)ethoxy]methyl]guanine (BIOLF-62) is highly synergistic with either phosphonoformate or phosphonoacetate when used in combination against herpes simplex virus types 1 and 2 in vitro. Acycloguanosine did not show significant synergism with these two compounds. Bromovinyldeoxyuridine and phosphonoformate were highly synergistic against herpes simplex virus type 2, bu...

Of nine herpes simplex virus 1 strains (from lip, mouth, throat, cornea, or brain) only five produced enough nonvirion antigen (i.e., not a structural component of the virus) to be detected by complement fixation with specially prepared, virion-absorbed, type-1 guinea pig antisera, while the remaining four strains produced only enough of the same antigen to induce specific antibody in hyperimmu...

Protein microarrays have been developed to study antibody reactivity against a large number of antigens, demonstrating extensive perspective for clinical application. We developed a viral antigen array by spotting four recombinant antigens and synthetic peptide, including glycoprotein G of herpes simplex virus (HSV) type 1 and 2, phosphoprotein 150 of cytomegalovirus (CMV), Rubella virus (RV) c...

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...

Four independent isolated lines transformed by ts mutant or sheared DNA of herpes simplex virus types 1 and 2 and one tumor cell line were characterized according to their behavior in assays of aggregation, growth in low serum, doubling times, saturation density, agglutination by lectins, uptake of metabolites, and production of plasminogen activator. The criteria used to select the transformed...

    Acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. Acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. Acyclovir triphosphate inhibits viral DNA-polymerase terminating the chain...

Investigations of serum antibody status to the five human herpesviruses--herpes simplex virus type 1, herpes simplex virus type 2, cytomegalovirus, Epstein-Barr virus, and varicella-zoster virus--were conducted on 197 Navajo children, aged 1-15 years, at a reservation pediatric outpatient clinic in Crownpoint, New Mexico, from 1981-1984. To determine the severity of infection with the human her...
