Total hemolytic complement (CH50) levels were compared in sera from normal hamsters and hamsters bearing tumors derived from herpes simplex virus type 2-transformed cells CH50 in normal sera ranged from 160 to 212 while CH50 in tumor bearer sera ranged from 82 to 146. Preincubation of tumor bearer sera with cell surface proteins (CSP) from homologous herpes simplex virus type 2-derived tumor ce...

Abstract Background and Aims: Herpes simplex virus (HSV) is a common cause of corneal disease and is the leading infectious cause of corneal blindness among developed nations. This study is aimed to provide an estimation of the incidence of Herpes Simplex Virustype-1, 2(HSV1, 2) and Varicella Zoster Virus (VZV) in tears and swab from eye infection by polymerase chain reaction (PCR) in eye ...

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...

Three consecutive patients with no apparent immunodeficiency who had frequent intraoral herpes simplex type 1 recurrences, a rare complication of herpes simplex virus infection, were found to have a total deficiency of either the A or B isotype of the complement component C4 and to be homozygous for the studied HLA antigens. A combination of HLA homozygosity, which may lead to impaired T cell r...

avicennia marina (avicenniaceae) is a species of mangrove tree used for treatment of small pox lesions in persian folk medicine. the antiviral activity of methanol, ethanol, water, chloroform and n-hexane extracts was evaluated against hiv-1 and hsv. methanol extract had the highest antiviral activity and the most polar fraction of this extract (fraction d) inhibited hsv with ti and si values o...

background: during the recent years, significant progress has been achieved on development of novel anti-viral drugs. natural products are assumed as the potential sources of novel anti-viral drugs; therefore, there are some previous studies reporting the anti-viral compounds from venomous animals. based on the significant value for tracing of non-toxic anti-viral agents from natural resources,...

background and aims: the latency-associated transcript (lat) transcribed by latent herpes simplex virus type-1 in neuron cells are able to influence their host cell pathways. while the most of previous studies were focused on anti-apoptotic effects of lat, our investigation is making an effort to explore lat potency on cell cycle pathway in neuroblastoma cell lines. methods: the evaluation of l...

a complication in the analysis of the role of icp34.5 gene in the herpes simplex virus type-1 (hsv-1) lifecycle is the presence of overlapping antisense gene, open reading frame p (orf p), which is also deleted in hsv-1 icp34.5 negative mutants. a hsv-1 wild type strain (17+) icp34.5/orf p deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...

An enzyme immunoassay (EIA) was developed for detecting antibody to herpes simplex virus, and the results were compared with those of complement fixation, indirect immunofluorescent-antibody, and plaque reduction neutralization tests. Test sera showed very little nonspecific reactivity even at a starting dilution as low as 1:10. EIA results showed excellent correlation with results obtained by ...
