| the diagnosis of recent herpes simplex virus type 2 genital infections by the simplex-2 test. | the prevalence of complement-fixing (cf) antibody against the ag-4 early antigen of herpes simplex virus (hsv) type 2 (hsv-2) was determined in patients with culture confirmed hsv-2 genital herpes and control groups using a commercial hsv-2 early antigen (simplex-2; gene link australia ltd). eighty seven per cent of 39 sera collected between 14 and 28 days after confirmed primary and recurrent hsv-2 infection were positive. in acute sera collected between 2-10 days after onset the simplex-2 test ... | 1992 | 1337770 |
| influence of t-actemodulin on herpes simplex virus infection. | the aim of the investigation was to study the direct influence of t-actemodulin (tam) on the herpes simplex virus (hsv) infection in vitro and in vivo. hsv-1 (strain vic) and hsv-2 (strain nissa) were used in the experiments in vitro. the experiments were performed using multicycle and singlecycle growth tests. seventy-five patients suffering from hsv infections (labialis and genitalis) were locally treated by 0.04% tam-containing hydrophilic gel or water-washable cream (applied every 3 h). the ... | 1992 | 1339076 |
| viruses in anogenital cancer. | the association between sexual activity and cancer, first described in carcinoma of the cervix, has been expanded to include the majority of anogenital squamous epithelial carcinomas. current evidence suggests that human papillomavirus (hpv) may be of great importance in the development of these tumours, whilst herpes simplex type 2 virus (hsv-2) and human immunodeficiency virus (hiv) may play minor roles. certain types of hpv dna, including types 16, 18, 31, 33 and 39 are found in most but not ... | 1992 | 1339181 |
| recurrent genital infection in the guinea pig: differences between herpes simplex types 1 and 2. | recurrence rates of genital infections are significantly higher for herpes simplex virus (hsv) type 2 than hsv type 1. reasons for this difference are not known. in this report, multiple strains of hsv-1 and hsv-2 were evaluated in the guinea-pig model. hsv-2 strains showed significantly higher genital lesion recurrence than hsv-1, including hsv-1 mckrae strain which is highly recurrent in ocular infections. hsv-2 strains were also associated with more frequent asymptomatic vaginal virus sheddin ... | 1992 | 1339184 |
| [envelope and membrane glycoproteins of herpes simplex virus]. | a bibliographic update on the herpes simplex virus (hsv) envelope is made with special emphasis on the membrane glycoproteins and their role in adsorption, spreading and escape of the immune response. the hsv has at least seven glycoproteins on its envelope; three out of them are essential for in vitro replication, they are designated as gb, gd and gh; four are dispensable: gc, ge, gi and gg. their main functions are: gc, gb and gd attach the virion to the cell surface, binding to molecules of h ... | 1992 | 1345300 |
| the glycoprotein b gene and its syn3 locus of herpes simplex virus type 1 are involved in the synthesis of virus-associated growth factor (hsgf-1). | a putative growth factor (hsgf-1) associated with herpes simplex virus type 1 (hsv-1), which is similar to prgf associated with pseudorabies virus, and/or hsgf-2 associated with hsv-2, was described. experiments with four syncytial (syn) and four nonsyncytial (syn+) hsv-1 strains showed that the ability of this virus to produce hsgf-1 in infected cells is associated with the syn+ phenotype. double infection of cells with syn+ and syn strain resulted either in enhancement or complete inhibition o ... | 1992 | 1363988 |

| localization of the antigenic sites and intrinsic protein kinase domain within a 300 amino acid segment of the ribonucleotide reductase large subunit from herpes simplex virus type 2. | the 140-kda ribonucleotide reductase (rr1) protein of herpes simplex virus type 2 (hsv-2) functions as the large subunit of virus-specified rr1 and exhibits an intrinsic protein kinase (pk) activity at its unique nh2-terminal region. the n-terminal half of rr1 contains the protein and dna functions of the morphological transforming region iii (mtriii) of hsv-2. in the present study, we have expressed a number of truncated rr1 derivatives in a mammalian expression vector containing nh2-terminal r ... | 1992 | 1371028 |
| computer prediction of antigenic and topogenic domains in hsv-1 and hsv-2 glycoprotein b (gb). | the envelope glycoprotein b (gb) coded for by the herpes simplex virus type 1 (hsv-1) ul27 gene is similar to the amino acid (aa) sequence of the gb coded by a homologous gene in hsv-2 dna. the putative antigenic domains in hsv-1 and hsv-2 gb glycoproteins were analyzed on a comparative basis by suitable computer programs, which allowed the prediction of putative antigenic and topogenic domains. the computer-derived domains were compared to experimentally reported antigenic domains in hsv-1 gb g ... | 1992 | 1375407 |
| protection from herpes simplex virus type 2 is associated with t cells involved in delayed type hypersensitivity that recognize glycosylation-related epitopes on glycoprotein d. | immunization of mice with a vaccinia recombinant (vp176) that expresses a fully glycosylated herpes simplex virus (hsv) glycoprotein d (gd) induces long-term (greater than or equal to 50 days) hsv-specific lymphoproliferation and delayed type hypersensitivity (dth) responses, the ability to eliminate a high challenge dose of hsv-2 from the epidermis and protection from fatal disease due to hsv replication in the nervous system. adoptive transfer studies indicate that protection is mediated by th ... | 1992 | 1376951 |
| in vitro toxicological evaluation of isis 1082, a phosphorothioate oligonucleotide inhibitor of herpes simplex virus. | isis 1082, a phosphorothioate oligonucleotide targeted to a translation initiation codon of herpes simplex virus type 1 (hsv-1) and herpes simplex virus type 2 (hsv-2) virion capsid protein ul13 inhibits in vitro viral replication. to better understand the pharmacological properties of isis 1082, we examined its effects in nonvirally infected hela cells by using a number of cytotoxicity assays. our data indicate that isis 1082 had no effect on hela cell viability as measured by cellular prolifer ... | 1992 | 1377898 |
| genetic analysis of type-specific antigenic determinants of herpes simplex virus glycoprotein c. | herpes simplex virus type 1 (hsv-1) glycoprotein c (gc-1) elicits a largely serotype-specific immune response directed against previously described determinants designated antigenic sites i and ii. to more precisely define these two immunodominant antigenic regions of gc-1 and to determine whether the homologous hsv-2 glycoprotein (gc-2) has similarly situated antigenic determinants, viral recombinants containing gc chimeric genes which join site i and site ii of the two serotypes were construct ... | 1992 | 1378512 |
| epitopes of herpes simplex virus type 1 glycoprotein b that bind type-common neutralizing antibodies elicit type-specific antibody-dependent cellular cytotoxicity. | a panel of 45 well-characterized monoclonal antibodies (mabs) reactive to glycoprotein b (gb) of herpes simplex virus (hsv) type 1 was tested by elisa and in antiviral functional assays (that included virus neutralization, antibody-dependent cellular cytotoxicity (adcc), and antibody-dependent complement-mediated lysis), using type 1 or 2 virus strains. all mabs were elisa-reactive. eleven of the mabs mediated neutralization and 9 mediated adcc. all of the adcc epitopes were contained within the ... | 1992 | 1380051 |
| soluble glycoprotein d blocks herpes simplex virus type 1 infection of rat eyes. | herpes simplex virus type 1 (hsv-1) ocular infection in rats was blocked by treating the eyes with uv-inactivated virions containing glycoprotein d (gd) prior to ocular challenge. in contrast, rats treated with uv-inactivated virions lacking gd were not protected. a soluble, truncated form of hsv-2 gd (gd-2t) also protected against ocular infection. treatment with gd-2t not only reduced mortality but also restricted progression of pathology and reduced the amount of viral antigen in the cornea. ... | 1992 | 1380093 |
| down-regulation of keratin 14 gene expression after v-ha-ras transfection of human papillomavirus-immortalized human cervical epithelial cells. | keratin expression in human cervical squamous cell carcinoma (scc) lines differed significantly from both normal and human papillomavirus (hpv) immortalized exocervical cells. keratin 14 (k14) expression, determined by protein synthesis and mrna levels, was dramatically down-regulated in the cervical scc lines while keratin 5 (k5) expression was not. k14 expression was similarly down-regulated in an hpv-16 immortalized cervical cell line after tumorigenic transformation with recombinant v-ha-ras ... | 1992 | 1382846 |
| vaccination by cholera toxin conjugated to a herpes simplex virus type 2 glycoprotein d peptide. | immunization of balb/cj mice with a peptide corresponding to residues 1 to 23 of glycoprotein d [gd(1-23)] from herpes simplex virus type 2 (hsv-2) elicits antibody responses which correlate with protection against lethal hsv-2 infection. in the present study, we examined the ability of cholera toxin (ctx) to act as an immunogenic carrier for gd(1-23). the number of gd(1-23) residues conjugated to ctx affected its binding to gm1 ganglioside and physiological toxicity, both of which are factors a ... | 1992 | 1383408 |
| herpes simplex virus infection induces a selective increase in the proportion of galanin-positive neurons in mouse sensory ganglia. | we examined the effects of herpes simplex virus type 2 (hsv-2) infection on host neuropeptide content in mouse dorsal root ganglia (drg) neurons following unilateral hind footpad inoculation. at selected survival times following infection, adjacent tissue sections of decalcified spine containing the paired 4th and 5th lumbar drgs were immunoreacted to detect hsv-2, calcitonin gene-related peptide (cgrp), or galanin antigen. labeled and unlabeled neurons were counted and the somal areas for all n ... | 1992 | 1385205 |
| fluorocontaining d-cycloserines. synthesis and in vitro evaluation of antimicrobial and antiviral activities. | some fluoroacylderivatives at the side chain nh2 of d-cycloserine were synthesized and evaluated in vitro for antimicrobial activity against bacteria and tubercular or non-tubercular mycobacteria. against the used gram-positive and gram-negative strains only trifluoroacetamide 1 exhibited comparable mic values and lower mbc values than those of parent antibiotic. other fluoroacycloserines, inactive at all on these bacteria, were found to inhibit the growth of mycobacteria when tested in liquid m ... | 1992 | 1388608 |

| in vitro virucidal effects of allium sativum (garlic) extract and compounds. | garlic (allium sativum) has been shown to have antiviral activity, but the compounds responsible have not been identified. using direct pre-infection incubation assays, we determined the in vitro virucidal effects of fresh garlic extract, its polar fraction, and the following garlic associated compounds: diallyl thiosulfinate (allicin), allyl methyl thiosulfinate, methyl allyl thiosulfinate, ajoene, alliin, deoxyalliin, diallyl disulfide, and diallyl trisulfide. activity was determined against s ... | 1992 | 1470664 |
| absence of genomes of dna tumor viruses and expression of oncogenes and growth factors in two esophageal carcinoma cell lines of chinese origin. | to study the oncogenesis of human esophageal carcinoma, the presence of dna sequences homologous to several dna tumor viruses and the expression of oncogenes and growth factor genes were examined in two esophageal carcinoma cell lines of chinese origin, ce48t/vgh and ce81t/vgh. southern blot analyses failed to detect sequences homologous to hepatitis b virus (hbv), epstein-barr virus (ebv), herpes simplex virus type 2 (hsv-2), cytomegalovirus (cmv) or human papilloma virus (hpv) genomes. norther ... | 1992 | 1473373 |
| evaluation of new anti-infective drugs for the treatment of genital infections due to herpes simplex virus. infectious diseases society of america and the food and drug administration. | this guideline addresses clinical trials of new therapies for genital infections due to herpes simplex virus (hsv). of the two types of virus, hsv-2 is the more common pathogen. both hsv-1 and hsv-2 become latent in sacral nerve root ganglia and intermittently reactivate. patients who have frequent recurrences (more than four per year) may be candidates for long-term suppressive therapy. in both first-episode and recurrent genital hsv infections, lesions should be cultured for hsv. testing for h ... | 1992 | 1477256 |
| cystic encephalomalacia and intrauterine herpes simplex virus infection. | cystic encephalomalacia occurred in two preterm infants who had proven intrauterine herpes simplex virus type 2 infection. calcification was evident in the basal ganglia. follow-up scans indicated that the cysts had resolved over a period of two months in one infant, while in the case of the other, the cysts became progressively larger with significant ventricular dilatation developing. while cystic changes in the brain of preterm infants are usually due to periventricular leukomalacia, intraute ... | 1992 | 1491914 |
| cholera toxin conjugates for intragastric vaccination against herpes simplex virus type 2. | in this study, we tested the hypothesis that enteric immunization with cholera toxin (ctx) conjugated to glycoprotein d (gd) of herpes simplex virus type 2 (hsv-2) or a peptide corresponding to residues (1-23) of gd (gd(1-23)) would induce relevant antiviral immunity. intraperitoneal (ip) immunization of mice with ctx-gd(1-23) conjugate induced anti-hsv-2 sera antibody responses which correlated with protection from a lethal ip challenge with hsv-2. intragastric (ig) immunization of mice with th ... | 1992 | 1503890 |
| identification of equine herpesvirus 4 glycoprotein g: a type-specific, secreted glycoprotein. | equine herpesvirus 4 (ehv4) glycoproteins of m(r) 63k and 250k were identified in the supernatant of infected cell cultures. the 63k glycoprotein was type-specific; that is, it reacted with monospecific sera from horses that had been immunized or infected with ehv4, but not with monospecific sera from horses immunized or infected with ehv1, a closely related alphaherpesvirus. it was postulated that the secreted protein may be the homologue of similarly secreted glycoproteins of herpes simplex vi ... | 1992 | 1529525 |
| outcome of herpes simplex virus type 2 infection in guinea pigs. | factors that influence the outcome of genital herpes simplex virus (hsv) infection were explored in a guinea pig model. the viral inoculum required to establish infection in 50% of animals (id50) was similar for inbred (strain 2) and outbred (hartley) guinea pigs. however, the viral inoculum required to produce clinical disease in 50% of the animals (cd50) was 10 times greater for strain 2 compared to hartley animals. hsv infection of both inbred and outbred animals was more likely to result in ... | 1992 | 1578222 |
| acute retinal necrosis syndrome. | 1. acute retinal necrosis (arn) represents a specific pattern of clinical presentations for certain herpes virus infections in the posterior segment of the eye. these include varicella zoster virus and herpes simplex virus. 2. patients with arn usually complain of mild to moderate ocular or periorbital pain, foreign body sensation, and a red eye. visual symptoms usually include hazy vision, floaters, and, rarely, decreased peripheral vision. 3. medical treatment of choice is intravenous acyclovi ... | 1992 | 1597865 |
| structural basis of c3b binding by glycoprotein c of herpes simplex virus. | glycoproteins c (gc) from herpes simplex virus type 1 (hsv-1) and hsv-2, gc-1 and gc-2, bind the human complement fragment c3b, although the two glycoproteins differ in their abilities to act as c3b receptors on infected cells and in their effects on the alternative complement pathway. previously, we identified three regions of gc-2 (i, ii, and iii) which are important for c3b binding. in this study, our goal was to identify c3b-binding sites on gc-1 and to continue our analysis of gc-2. we cons ... | 1992 | 1602532 |
| herpes simplex virus type 2 infection and cervical cancer: a prospective study of 12 years of follow-up in finland. | this study was initiated to investigate the role of past herpes simplex virus type 2 (hsv-2) infection, as determined by serum antibody analysis, in the etiology of cervical neoplasia. two finnish registers, the registry of the social insurance institution's mobile clinic survey and the finnish cancer registry, were linked. about 40,000 blood samples were drawn in 1968-72 and stored by the social insurance institution. according to the cancer registry, 32 cases of cervical carcinoma or carcinoma ... | 1992 | 1617120 |
| endemic disease, nutrition and fertility in developing countries. | subfecundity is caused by disease and nutrition as well as by genetic, environmental, and psychological components. sexually transmitted diseases (stds) are caused by 21 different pathogens of which syphilis, gonorrhea, and chlamydia are the most important. syphilis is caused by the bacterium treponema pallidum with incidence of 10% in thailand. 20% in papua new guinea, and 40% in ethiopia. stillbirths in infected mothers range from 66% to 80%. gonorrhea is caused by the bacterium neisseria ... | 1992 | 1634564 |
| evaluation of five monoclonal antibody-based kits or reagents for the identification and culture confirmation of herpes simplex virus. | five immunofluorescence (if) kits or reagents (bartels [bartels immunodiagnostic supplies, inc., bellevue, wash.], imagen [celltech diagnostics, ltd., distributed by analytab products, plainview, n.y.], ortho [ortho diagnostics systems, inc., raritan, n.j.], syva [syva co., palo alto, calif.], whittaker [whittaker bioproducts, walkersville, md.]) were evaluated for typing and laboratory confirmation of herpes simplex virus (hsv). of 101 clinical isolates tested by each kit or reagent, results fo ... | 1991 | 1645367 |
| icp4, the major regulatory protein of herpes simplex virus, shares features common to gtp-binding proteins and is adenylated and guanylated. | infected cell protein 4 (icp4), the product of the alpha 4 gene, regulates herpes simplex virus 1 and herpes simplex virus 2 gene expression at the transcriptional level both positively and negatively. previous studies have shown that icp4 is extensively modified posttranslationally. we report that icp4 was labeled in isolated nuclei of infected cells by [alpha-32p]gtp or [alpha-32p]atp. the labeling of icp4 by [alpha-32p]gtp or [alpha-32p]atp required excess gtp, atp, gdp, and adp and occurred ... | 1991 | 1645791 |
| native herpes simplex virus glycoprotein d vaccine: immunogenicity and protection in animal models. | mice, guinea pigs, and rhesus monkeys were immunized with immunoaffinity-purified native glycoprotein d (gd) derived from herpes simplex virus type 1 (hsv1). the native glycoprotein has evoked significant in vivo responses even at low doses. thus, mice immunized with doses as low as 1 microgram were significantly protected from the morbidity and mortality of lethal hsv2 challenge and from establishment of latent hsv2 infection. protection was dose-related and correlated with prechallenge serum n ... | 1991 | 1645898 |
| differentiation of herpes simplex virus-induced fusion from without and fusion from within by cyclosporin a and compound 48/80. | treating strains of herpes simplex virus (hsv) in culture with either cyclosporin a or compound 48/80, allowed the strains to be divided into two groups. group 1 contains the strains ang and hfem of hsv-1 and lux syn (hsv-2) producing fusion from within (ffwi) and fusion from without (ffwo). cyclosporin a fails to inhibit both types of fusion at concentrations up to 100 microm. strains ang and hfem belong to the syn 3 marker locus group identified for hsv-1. group 2 contains all other fusion-pro ... | 1991 | 1646277 |
| the simian herpesvirus sa8 homologue of the herpes simplex virus gb gene: mapping, sequencing, and comparison to the hsv gb. | the genomic location and dna sequence of the simian herpesvirus sa8 gene encoding a homologue of the hsv1 gb glycoprotein was determined. using a cloned gb gene of herpes simplex virus type 1 (hsv1) as probe in southern blot hybridizations, the sa8 gb gene was localized to a 10-kbp kpni fragment mapping in the unique long part of the genome. a 2.8 kbp, 68.4% gc segment of this fragment was sequenced. it contained a 2649 nucleotide orf possibly encoding a 98.4 kda polypeptide. the predicted amino ... | 1991 | 1646593 |

| rheumatoid factors react with fab fragments of monoclonal antibodies to herpes simplex virus types 1 and 2 fc gamma-binding proteins. | human polyclonal igm rheumatoid factors (rf) were tested in an enzyme-linked immunosorbent assay with monoclonal antibodies (mab) (ii-481 and b10/a8) to glycoprotein e (ge), the fc gamma-binding protein of herpes simplex virus type 1 (hsv-1), as well as with mab 88-s to ge of hsv-2. most of the rf reacted with ii-481 and 88-s. positive reactions were recorded for rf reacting with whole mab ii-481 and 88-s, as well as with their fab, but not their fc, fragments. human monoclonal igm rf isolated f ... | 1991 | 1647772 |
| restriction endonuclease patterns of herpes simplex virus dna: subtyping of hsv-1 and hsv-2 strains from genital and nongenital lesions. | herpes simplex type 1 (hsv-1) and type 2 (hsv-2) isolates from genital and nongenital infections were submitted to restriction endonuclease analysis for possible genomic changes in relation with the adaptation of the virus to a new site on the body. hsv-1 and hsv-2 strains were successfully divided into two subgroups using the hin c ii restriction enzyme. no correlation was found, however, between the proposed genomic subtypes h1a, h1b, h2a and h2b, and the genital or nongenital origin of the hs ... | 1991 | 1647930 |
| herpes and human ribonucleotide reductases. inhibition by 2-acetylpyridine 5-[(2-chloroanilino)-thiocarbonyl]-thiocarbonohydrazone (348u87). | the mode of inactivation of herpes simplex virus type 1 and human ribonucleotide reductases by 2-acetylpyridine 5-[(2-chloroanilino)-thiocarbonyl]-thiocarbonohydrazone++ + (348u87) was determined and compared to that described previously [porter et al. biochem pharmacol 39: 639-646, 1990] for 2-acetylpyridine 5-[(dimethylamino)thiocarbonyl]-thiocarbonohydrazone (a1110u). 348u87 inactivated herpes ribonucleotide reductase faster than did a1110u. moreover, iron-complexed 348u87 was a considerably ... | 1991 | 1648925 |
| [monoclonal antibodies to herpes simplex viruses antigens--specificity and utility in rapid serotyping of clinical isolates]. | sixteen hybridomas secreting antibodies to hsv-1 and 22 hybridomas secreting antibodies to hsv-2 were derived from fusion of sp2/0 myeloma cells with spleen cells from balb/c mice immunized with each respective virus. four of the former 16 hybridomas and seven of the latter 22 hybridomas were subcloned and injected into pristane-primed mice to obtain high titers of monoclonal antibodies. antigen specificity of these monoclonal antibodies were determined by the western blotting (wb) assay. two ou ... | 1991 | 1649232 |
| complementary lethal invasion of the central nervous system by nonneuroinvasive herpes simplex virus types 1 and 2. | it is well-known that viral thymidine kinase (tk) expression is important for the maximum demonstration of virulence of herpes simplex virus (hsv). in this study, we have investigated interactions of a tk- mutant of virulent hsv type 2 (hsv-2) (syn+) and a nonneuroinvasive hsv-1 (syn) in mice. when the mice were inoculated with each virus alone in their rear footpads, no mice were killed even after infection with high doses of viruses (greater than 10(6) pfu per mouse), whereas 100% of the mice ... | 1991 | 1649347 |
| synergistic topical therapy by acyclovir and a1110u for herpes simplex virus induced zosteriform rash in mice. | combination therapy with a1110u, an inactivator of the herpes simplex virus (hsv) and the varicella zoster virus ribonucleotide reductase, and acyclovir (acv) was evaluated for treatment of cutaneous herpetic disease in athymic mice infected on the dorsum. in this model, infection with hsv produces a 'zosteriform-like' rash that is first visible on day 3 or 4 post-infection (p.i.) and eventually extends from the anterior mid-line to the dorsal mid-line of the affected flank. in untreated mice, t ... | 1991 | 1650166 |
| efficacy of 9-(2-phosphonylmethoxyethyl)adenine in the therapy of tk+ and tk- herpes simplex virus experimental keratitis. | the acyclic nucleoside phosphonate analogue pmea [9-(2-phosphonylmethoxyethyl)adenine] is a broad spectrum antiviral agent effective against dna viruses and retroviruses. it is particularly active against the human immunodeficiency virus and, like other phosphonylmethoxyalkyl derivatives, it also inhibits hsv-1, tk- hsv-1 and hsv-2. we have evaluated the therapeutic efficacy of pmea in the hsv-1 and tk- hsv-1 experimental keratitis models using bvdu (bromovinyldeoxyuridine) as the reference comp ... | 1991 | 1650660 |
| protective effect of anti-glycoprotein d antibody on herpetic chorioretinitis in newborn rabbits. | subcutaneous injection of type 2 herpes simplex virus (hsv-2) (10(3) pfu) to newborn rabbits produced severe skin lesions and wide dissemination of the virus to various organs including the eye. ocular lesions were characterized by retinal folds and choroiditis. hsv could be isolated from mononuclear cells (mncs) of infected animal blood. newborn rabbits treated with monoclonal antibody (mab) against glycoprotein d (gd) of hsv on days 0, 2 and 4 postinfection had little or no skin lesions (0.0-2 ... | 1991 | 1650664 |
| differences in the capacity of two herpes simplex virus isolates to spread from eye to brain map to 1610 base pairs of dna found in the gene for dna polymerase. | a intertypic recombinant, designated hsv-r(d1), had previously been generated from non-neuroinvasive hsv-2(186) and neuroinvasive hsv-1(17). although the recombinant contained less than 2% of the hsv-1 genome, it retained the neuroinvasive phenotype. the nucleotide sequences responsible for the neuroinvasiveness of hsv-r(d1) were previously mapped to a 3.0 kb segment of dna located within the dna polymerase gene (mu 0.414 to 0.430) via marker rescue experiments. we have now sequenced this region ... | 1991 | 1650671 |
| evidence endogenous interferon production contributed to the lack of ocular virulence of an hsv intertypic recombinant. | an intertypic recombinant isolated from rabbit kidney cells following co-transfection of hsv-1(17) and hsv-2(186) dna failed to induce overt ocular pathology when inoculated onto the murine sacrificed cornea at concentrations as high as 10(7) pfu per eye. in contrast, both parents induced corneal disease at a 1000-fold lower dose. the reason(s) for the failure of the intertypic recombinant, designated ro25x, to induce corneal pathology was investigated. it was found that the recombinant was 100- ... | 1991 | 1650672 |
| necrotizing myelopathy associated with malignancy caused by herpes simplex virus type 2: clinical report of two cases and literature review. | two cases of necrotizing myelopathy, one with lung carcinoma and the other with adult t cell leukemia (atl), displayed flaccid paraplegia and sphincter dysfunction. both cases did not show any direct neoplastic cell invasion of the spinal cord. pathologically, diffuse and random necrosis was found in the spinal cord in both cases. in the case of atl, small numbers of inclusion bodies in the nerve cell nuclei were demonstrated. using polyclonal and also monoclonal antibodies, herpes simplex virus ... | 1991 | 1650859 |
| synthesis and anticancer and antiviral activities of various 2'- and 3'-methylidene-substituted nucleoside analogues and crystal structure of 2'-deoxy-2'-methylidenecytidine hydrochloride. | various 2'- and 3'-methylidene-substituted nucleoside analogues have been synthesized and evaluated as potential anticancer and/or antiviral agents. among these compounds, 2'-deoxy-2'-methylidene-5-fluorocytidine (22) and 2'-deoxy-2'-methylidenecytidine (23) not only demonstrated potent anticancer activity in culture against murine l1210 and p388 leukemias, sarcoma 180, and human ccrf-cem lymphoblastic leukemia, producing ed50 values of 1.2 and 0.3 microm, 0.6 and 0.4 microm, 1.5 and 1.5 microm, ... | 1991 | 1652024 |

| nucleotide and deduced amino acid sequences of the gene encoding virion protein 16 of herpes simplex virus type 2. | a virion protein (vp16) of herpes simplex virus (hsv) activates transcription of viral immediate-early genes. we have determined the nucleotide sequence of the virion activator gene from hsv-2, which we term vp16-2. comparison of the deduced amino acid sequences of the hsv-1 and hsv-2 homologs shows that the vp16-2 gene product retains features determined to be important for transcriptional activation by vp16. | 1991 | 1653757 |
| seroreactive recombinant herpes simplex virus type 2-specific glycoprotein g. | the herpes simplex virus type 2 (hsv-2) genome codes for an envelope protein, glycoprotein g (gg), which contains predominantly type 2-specific epitopes. a portion of this gg gene has been expressed as a fusion protein in escherichia coli. expression was regulated by a lambda phage pl promoter. the 60,000-molecular-weight recombinant protein was purified by ion-exchange chromatography. amino acid sequence analysis confirmed the n terminus of the purified protein. mice immunized with recombinant ... | 1991 | 1653787 |
| herpes simplex virus glycoprotein c is a receptor for complement component ic3b. | herpes simplex virus type 1-infected cells bind c3b and ic3b, but not c3d, at the cell surface. herpes simplex virus type 2 (hsv-2)-infected cells bind none of these c3 fragments. a transfection assay was used to demonstrate that binding of ic3b was to gc1. although ic3b did not bind to hsv-2-infected cells, it did bind to mammalian cells transfected with the gc2 gene. using linker insertion mutants, three domains on gc2 that are important for binding ic3b were mapped; these regions were similar ... | 1991 | 1654359 |
| cleavage of the bovine herpesvirus glycoprotein b is not essential for its function. | herpes simplex virus glycoprotein b (hsvgb) and its bovine herpesvirus homologue (bhvgb) share similar primary structures. these glycoproteins are present in the envelope of the virion and are believed to initiate infection by fusing the virus envelope with a host cell membrane. bhvgb, like the membrane-fusing glycoproteins of most enveloped viruses, is normally cleaved and is present as a disulphide-linked complex in the virus envelope and host cell membranes. hsvgb, however, remains uncleaved, ... | 1991 | 1654372 |
| the rl neurovirulence locus in herpes simplex virus type 2 strain hg52 plays no role in latency. | we have demonstrated that the variant jh2604 of the herpes simplex virus type 2 (hsv-2) strain hg52 is completely avirulent in balb/c mice following intracranial inoculation, with an ld50 of greater than 10(7) p.f.u./mouse compared to the wild-type ld50 of less than 10(2) p.f.u./mouse. in jh2604, a 1.5 kbp deletion extends from the dr1/ub junction of the 'a' sequence to 511 bp upstream of the 5' end of ie1 in both long repeats. we have since constructed a second variant (2701) in which only 850 ... | 1991 | 1654382 |
| the nucleotide sequence, 5' end, promoter domain, and kinetics of expression of the gene encoding the herpes simplex virus type 2 latency-associated transcript. | the sequence of the herpes simplex virus type 2 (hsv-2) latency-associated transcript (lat) region resembles that of hsv-1 only where the lats overlap icp0 and in the putative promoter region. otherwise, the lat 5' ends, kinetics of expression, and promoter elements are mostly conserved between hsv-1 and hsv-2. the remaining differences between the lats could contribute to each virus's distinctive pattern of reactivation. | 1991 | 1654458 |
| enhanced malignant transformation induced by expression of a distinct protein domain of ribonucleotide reductase large subunit from herpes simplex virus type 2. | the 1.3-kilobase (kb) pst i dna fragment c (pst i-c) of herpes simplex virus type 2 (hsv-2) morphological transforming region iii (mtriii; map unit 0.562-0.570) encodes part of the n-terminal half of the large subunit of ribonucleotide reductase (rr1; amino acid residues 71-502) and induces the neoplastic transformation of immortalized cell lines. to assess directly the role of these rr1 protein sequences in cell transformation, the pst i-c fragment was cloned in an expression vector (p91023) co ... | 1991 | 1654564 |
| modulation of lymphoproliferation and oxidative burst by herpes-transformed tumors. | in this study, herpes simplex virus type 2 (hsv-2)-transformed cells (h238) and conditioned medium (cm) from h238 cell cultures were studied with respect to their effects on lymphoproliferation and the chemiluminescent oxidative burst of phagocytic cells. the h238 cells expressed a nuclear antigen detectable by fluorescent antibody testing using pooled sera from tumor-bearing mice, but no hsv-1 or hsv-2 cell membrane antigens could be found using specific monoclonal antibodies. balb/c mice subcu ... | 1991 | 1654931 |
| screening pregnant women for genital herpes. | in a prospective study to identify the viral type isolated from women undergoing screening for herpes simplex virus (hsv) during pregnancy using fluoroscine-labelled monoclonal antibodies to hsv-1 and hsv-2, hsv-2 was more likely to be isolated during the third trimester and was the only viral type isolated at term. as the severity of neonatal central nervous system disease is greater with hsv-2 than hsv-1 we recommended that all women with a history of genital herpes should be screened during p ... | 1991 | 1655058 |
| genital warts, other sexually transmitted diseases, and vulvar cancer. | to determine whether specific sexually transmitted diseases were associated with an increased risk of vulvar cancer, we conducted a case-control study among residents of three countries in western washington. we identified, interviewed, and obtained blood samples from women with in situ (n = 180) and invasive (n = 53) vulvar cancer, 18-79 years of age, who were first diagnosed with these diseases during 1980-1988. we compared their responses with those of 466 women from the general population wh ... | 1991 | 1655066 |
| herpes simplex virus type 2: a possible interaction with human papillomavirus types 16/18 in the development of invasive cervical cancer. | a case-control study of 766 histologically confirmed incident cases of invasive cervical cancer and 1,532 hospital and community controls was conducted in latin america to evaluate the etiologic role of herpes simplex virus type 2 (hsv-2) and to examine whether hsv-2 interacts with other risk factors. in addition to a personal interview, all subjects were asked to donate blood samples and cervical swabs for assessment of exposure to hsv-2 and human papillomaviruses (hpvs) respectively. ninety-ei ... | 1991 | 1655658 |
| the herpes simplex virus 1 protein kinase encoded by the us3 gene mediates posttranslational modification of the phosphoprotein encoded by the ul34 gene. | earlier studies have shown that a herpes simplex virus 1 (hsv-1) open reading frame, us3, encodes a novel protein kinase and have characterized the cognate amino acid sequence which is phosphorylated by this enzyme. this report identifies an apparently essential viral phosphoprotein whose posttranslational processing involves the viral protein kinase. analyses of viral proteins phosphorylated in the course of productive infection revealed a phosphoprotein whose mobility was viral protein kinase ... | 1991 | 1656069 |
| evaluation of sq 34,514: pharmacokinetics and efficacy in experimental herpesvirus infections in mice. | the new antiviral nucleoside sq 34,514 [(1r-1 alpha, 2 beta, 3 alpha)-2-amino-9- [2,3-bis(hydroxymethyl)cyclobutyl]-6h-purin-6-one], the active r isomer of racemic sq 33,054 (cyclobut-g), was evaluated for efficacy in the treatment of herpesvirus infections in mice. sq 34,514 was orally efficacious in a herpes simplex virus type 1 (hsv-1) systemic infection, an intracerebral hsv-2 infection, a vaginally induced hsv-2 infection in ovariectomized mice, and in a systemic murine cytomegalovirus infe ... | 1991 | 1656863 |
| clinical and serologic features of herpes simplex virus infection in patients with aids. | we studied the natural history of herpes simplex virus (hsv) infection and its association with specific serum antibody in a sample of 68 hiv-infected patients with a first episode of pneumocystis carinii pneumonia at san francisco general hospital in 1986. seroprevalence was 66 and 77% for hsv-1 and hsv-2 antibody, respectively, by immunoblot assay. twenty-seven patients had 45 hsv outbreaks diagnosed during 739 patient-months of follow-up. median frequency of recurrence resulting in a medical ... | 1991 | 1657040 |
| herpes simplex virus type 1 that exhibits herpes simplex virus type 2 sensitivity to (e)-5-(2-bromovinyl)-2'-deoxyuridine. | a clinical isolate, designated 145, of herpes simplex virus (hsv) had type 1 characteristics as determined by monoclonal antibody immunofluorescence, heat stability of viral thymidine kinase (tk), bamhi restriction endonuclease pattern, and absence of the hsv-2-specific 38-kd protein. however, instead of being sensitive to e-5-(2-bromovinyl)-2'-deoxyuridine (bvdu) like hsv-1, isolate 145 displayed a resistance pattern like hsv-2 to the drug as determined by viral replication and viral dna synthe ... | 1991 | 1657822 |
| a truncated protein kinase domain of the large subunit of herpes simplex virus type 2 ribonucleotide reductase (icp10) expressed in escherichia coli. | the amino-terminal domain of the large subunit of herpes simplex virus type 2 ribonucleotide reductase (icp10) contains a serine/threonine-specific protein kinase that has characteristics of a growth factor receptor (chung, t. d., wymer, j. p., smith, c. c., kulka, m., and aurelian, l.

| abolition of the rl neurovirulence phenotype of herpes simplex virus type 2 strain hg52 does not require deletion of the dr1 element of the 'a' sequence. | we have characterized a spontaneous variant of herpes simplex virus type 2 (hsv-2) strain hg52, 2616, which has 786 bp of both copies of rl deleted, but which retains 782 bp upstream of the 5' end of immediate early gene 1 and 463 bp downstream of the 'a' sequence. variant 2616 is avirulent following intracerebral inoculation of balb/c mice, thus showing in vivo characteristics similar to those of variant 2604, described previously (a 1488 bp deletion incorporating the dr1 element of the 'a' seq ... | 1991 | 1658204 |
| sequence, function, and regulation of the vmw65 gene of herpes simplex virus type 2. | we determined the sequence of the gene for the virion transactivator protein vmw65 of herpes simplex virus type 2 (hsv-2), strain 333. an analysis of the coding sequence revealed an overall high degree of primary sequence conservation (86%) relative to the hsv-1 protein, although the carboxy-terminal region which encompasses the powerful acidic transactivation domain of the hsv-1 protein was slightly less well conserved (70%). one important change in this region was the presence of a proline res ... | 1991 | 1658370 |
| effects of cytokines and r-837, a cytokine inducer, on uv-irradiation augmented recurrent genital herpes in guinea pigs. | we have recently reported that latently hsv-2-infected guinea pigs exhibit a three- to four-fold increase in recurrent lesions after exposure to ultraviolet radiation (uv), allowing rapid evaluation of antiviral drugs in treating recurrent hsv disease. in this report we examine the effect of alpha interferon (ifn-alpha), interleukin-2 (il-2), and a cytokine inducer (r-837) on uv-induced recurrent genital herpes. we have previously shown that topical r-837 is a biologic response modifier with no ... | 1991 | 1659313 |
| development and evaluation of an elisa using secreted recombinant glycoprotein b for determination of igg antibody to herpes simplex virus. | an elisa for the determination of igg antibody to herpes simplex virus (hsv) was developed using a secreted recombinant hsv-1 glycoprotein b (gb-1s) as a solid phase. the clinical validity of the elisa was established by testing different groups of sera containing hsv-1, hsv-2, or mixed antibody, in parallel with gb-1s elisa and conventional hsv-1/hsv-2 elisa. the new gb-1s elisa detected hsv-1/hsv-2 antibody in sera from 48 subjects with either hsv-1 or hsv-2 past infection as well as in sera f ... | 1991 | 1659581 |
| the pathogenicity of ribonucleotide reductase-null mutants of herpes simplex virus type 1 in mice. | the pathogenicity of ribonucleotide reductase (rr)-null mutants (hrr3 and icp6 delta) of herpes simplex virus (hsv) type 1 was studied after intracerebral and corneal inoculation in newborn and adult icr mice. icp6 delta failed to replicate in brains of mice greater than or equal to 8 days old but exhibited significant virulence for newborn mice as a result of viral replication in the brains. the rr- and a thymidine kinase (tk)-deficient mutant of hsv-1 strain kos could grow in eye tissues of ad ... | 1991 | 1659596 |
| evaluation of a test based on baculovirus-expressed glycoprotein g for detection of herpes simplex virus type-specific antibodies. | an immunoblot assay for discrimination of antibodies to herpes simplex virus (hsv) types 1 and 2 was devised using extracts of recombinant-baculovirus-infected insect cells expressing hsv-1 or -2 glycoprotein g (gg1 or gg2). the assay was evaluated by comparing its results with those obtained by using an immunodot assay based on gg immunopurified from hsv-1- and hsv-2-infected cells. each of 110 human serum specimens was tested blindly and independently three times. at a serum dilution of 1:20, ... | 1991 | 1659601 |
| recurrent herpes simplex virus type 2 encephalitis in a preterm neonate. favourable outcome after prolonged acyclovir treatment. | we describe a case of recurrent herpes simplex virus type 2 (hsv-2) central nervous system infection in a preterm neonate. on two occasions, encephalitis occurred together with eruption of vesicles on the right arm, and the patient was treated with acyclovir. new recurrences of vesicles followed each attempt to discontinue antiviral treatment, and prompted a continuous long-term acyclovir prophylaxis. at three years of age, the patient has developed normally. the use of immunoblotting for serolo ... | 1991 | 1659768 |
| suppression of immune responses by herpes virus type 2-transformed murine tumor cells. | work done in our laboratories, using a murine model, indicates that suppression of host immune responses might be due to secretion of soluble factors by tumor cells. the h238 cells (balb/c embryonic fibroblasts transformed by uv-inactivated herpes simplex virus type 2) exhibit progressive tumor growth with subsequent decrease in lymphoproliferation. to further study the suppressive effects of a tumor, h238 conditioned medium (cm) was tested for its ability to block murine and human mitogenic and ... | 1991 | 1660030 |
| antiviral activity of 1-docosanol, an inhibitor of lipid-enveloped viruses including herpes simplex. | this article reports that 1-docosanol, a 22-carbon-long saturated alcohol, exerts a substantial inhibitory effect on replication of certain viruses (e.g., herpes simplex virus and respiratory syncytial virus) within primary target cells in vitro. to study the basis for its viral inhibitory activity, a suspension of 1-docosanol was formulated in an inert and nontoxic surfactant, pluronic f-68; this suspension exerted potent inhibitory activity on the ability of susceptible viruses to infect cultu ... | 1991 | 1660151 |
| apical expression of herpes simplex virus type 2 glycoproteins in human neuroblastoma cells. | the expression of herpes simplex virus type 2 (hsv-2) glycoproteins on the surface of human neuroblastoma cells has been investigated using millipore millicell culture plate inserts. utilizing a modified radioimmunoassay, we learned that glycoproteins b, c, d, e, and i were expressed predominantly on the apical membrane domain of the infected neuroblastoma cells. the unidirectional transport of hsv-2 glycoproteins was substantiated by the analysis of extracellular glycoproteins released from neu ... | 1991 | 1660208 |
| improved detection of hsv by electron microscopy in clinical specimens using ultracentrifugation and colloidal gold immunoelectron microscopy: comparison with viral culture and cytodiagnosis. | three tests were compared to diagnose herpes virus infection: electron microscopy (em), viral culture (vc) and cytodiagnosis (tzanck smear). the study comprised 67 patients with skin or mucous membrane lesions suggestive of herpes simplex virus (hsv) infection. the sensitivity of em increased 25% after virus concentration by ultracentrifugation. herpes virus infection was confirmed in 55 of the 67 cases by em or vc or both. em detected 53 herpes virus-positive lesion samples of which 14 were not ... | 1991 | 1660490 |
| efficacy of hsv-1 iscom vaccine in the guinea-pig model of hsv-2 infection. | the capability of a herpes simplex virus (hsv)-1 iscom vaccine to protect against intravaginal hsv-2 challenge infection in guinea-pigs is described. the protective efficacy of the hsv-1 iscom vaccine is compared with that of a purified, aqueous hsv-1 antigen preparation administered using a similar immunization schedule. the results show that female guinea-pigs immunized with two doses of hsv-1 iscom vaccine, each consisting of 20 micrograms of protein given 2 weeks apart responded with high el ... | 1991 | 1661978 |
