A series of twelve recently synthesized 6-substituted derivatives of 9-beta-d-ribofuranosylpurine 3',5'-cyclic phosphate (RPcMP) were evaluated for in vitro antiviral activity, using inhibition of viral cytopathogenic effect as the primary parameter for evaluation. Inhibition of the development of intra- and extracellular virus titer was used as a secondary criterion with certain viruses. Five ...

Concurrent reactivation of herpes simplex and varicella zoster viruses is rare. Here, we describe the case of an elderly patient with herpes labialis and herpes zoster manifesting as a right-side facial eruption with vesicles and crusting. The loop-mediated isothermal amplification (LAMP) assay demonstrated the presence of both herpes simplex virus type 1 and varicella zoster virus in swab samp...

IgG viral antibodies for herpes simplex virus -1, varicella zoster virus, cytomegalovirus, measles and mumps were studied in 76 subjects with obsessive compulsive disorder and compared with a control population. There was a significantly higher titre for some of the antibodies, most specifically for herpes simplex virus type 1 and mumps. This suggests a possible role for these viral infections ...

As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furt...

BHK-21 cells infected with temperature-sensitive mutants of herpes simplex virus type 1 strain KOS representing 16 complementation groups were tested for susceptibility to complement-mediated immune cytolysis at permissive (34 degrees C) and nonpermissive (39 degrees C) temperatures. Only cells infected by mutants in complementation group E were resistant to immune cytolysis in a temperature-se...

We describe a case of chronic atypical herpes simplex type 2 encephalitis in an immunocompromised 68 year old man presenting with headache and cognitive changes without focal neurological or MRI findings. To our knowledge this is the first described case of herpes simplex encephalitis associated with normal MRI brain imaging and non-focal neurological examination. This further expands the range...

Lymphocyte blast transformation and interferon production in mononuclear cell culture prepared on Ficoll-Hypaque gradients from individuals with herpes simplex virus-I infection were enhanced by a disease recurrence. Responses to both herpes simplex virus-2 and phytohemagglutinin were unaltered. Transformation to herpes simplex virus-I antigen was adversely affected by depleting either thymus-d...

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...

Herpes simplex virus 1 contains seven genes that are necessary and sufficient for origin-dependent DNA synthesis in cultured cells. We have expressed the product of one of these genes, UL9, in insect cells by using a baculovirus expression vector. The apparent size of the UL9 protein, both in insect cells and in herpes simplex virus-infected Vero cells, is 82,000 Da. By using an immunoassay for...

Inhibitors of cell enzyme Inosine 5 ́-Monophosphate (IMP) dehydrogenase – Ribavirine (Rbv), Micophenolic acid (MPA) and Mizoribine (MZR) have potential application as antiherpes agents in combination with acyclovir (ACV). The effectivity of action of ACV on herpesvirus replication is improved after decreasing of the concentration of dGTP as a result of IMP dehydrogenase inhibition. The antiviral...
