| genomic location and lack of phosphorylation of the hsv immediate-early polypeptide ie 12. | herpes simplex virus type 1 (hsv-1) induces an immediate-early (ie) polypeptide ie 12. an equivalent polypeptide coded by hsv-2 which migrated slightly more slowly on sds-polyacrylamide gels was identified and designated ie 12.3. analysis of the serotype of the ie polypeptide induced by five hsv-1/hsv-2 intertypic recombinants when correlated with their genome structures showed that ie 12/ie 12.3 mapped in the region spanning the trs/us junction. unlike four other ie polypeptides induced by hsv- ... | 1982 | 6290593 |
| [morphological, cytogenetic and proliferative characteristics of syrian hamster htc-2 and htc-1 cells and of the htct tumor cell line transformed by herpes simplex type 2 virus]. | morphological, caryological, cytoproliferative, and isoenzyme studies of syrian hamster cells htc-2 and htc-1 transformed by herpes simplex virus type 2 and a htct line of tumor cells were carried out. the hamster origin of these cell lines was established by chromosomal analysis and electrophoretic mobility of lactate dehydrogenase and glucose-6-phosphate-dehydrogenase isoenzymes. the transformed and tumor cell lines differ from normal cells by altered morphology, an aneuploid chromosome set an ... | 1982 | 6291246 |
| capacity of deoxycytidine to selectively antagonize cytotoxicity of 5-halogenated analogs of deoxycytidine without loss of antiherpetic activity. | enzyme kinetic studies from this laboratory (m. dobersen and s. greer, biochemistry 17:920-928, 1978) suggested that deoxycytidine could antagonize the toxicity of 5-halogenated analogs of deoxycytidine without interfering with their antiviral activity. antagonism by deoxycytidine of the toxicity of 5-chlorodeoxycytidine without impairing its anti-herpes simplex virus type 2 activity is demonstrated in the present studies. tetrahydrouridine, an inhibitor of cytidine deaminase, was utilized. the ... | 1982 | 6291452 |
| genital herpes simplex infections in israel: 1973 throughout 1980. | ninety-eight cases of genital herpes simplex virus infection (hsv-2) were confirmed by laboratory examinations during the years 1973-80. until 1975 there were less than five cases per year, but from 1976 the number of cases gradually increased, reaching 24 in 1980. the age distribution is typical of a sexually transmitted disease; and since the peak of susceptibility is at childbearing age, an increase in neonatal hsv infection could be expected. in 1980, laboratory testing confirmed neonatal hs ... | 1982 | 6292133 |
| correlation of the virus sequence content and biological properties of cells carrying the herpes simplex virus type 2 thymidine kinase gene. | seven cell lines, transformed to a thymidine kinase-positive phenotype with herpes simplex virus type 2 (hsv-2) dna fragments, have been examined to determine their virus-specific dna sequence content. the results are consistent with the reported map position of the hsv-2 thymidine kinase gene. different cell lines contained different amounts of non-selected virus-specific sequences and this correlated with the ability of some cell lines to compensate the deficiencies in some temperature-sensiti ... | 1982 | 6292338 |
| transfection with the isolated herpes simplex virus thymidine kinase genes. i. minimal size of the active fragments from hsv-1 and hsv-2. | we have defined the minimal size and physical map locations in the genomes of both herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) for dna sequences capable of conferring stable biochemical transformation under thymidine kinase (tk) selection. the experiments involved transfection of ltk- cells with either isolated virus dna fragments or cloned pbr322 plasmids containing the 3.5 kilobase (kb) bamhi-o fragment from hsv-1(mp) or the 5.6 kb sali-g fragment from hsv-2(333). mapping of restricti ... | 1982 | 6292348 |
| isolation and characterisation of two strains of herpesvirus hominis type 1 from fallopian tubes. | herpesvirus hominis type 1 (hsv-1) was isolated from fallopian-tube biopsies of two women who were using an intra-uterine contraceptive device; the strains were isolated on different dates and at different hospitals. both the isolates were shown to be hsv-1 by restriction-enzyme analysis, polypeptide profiles and indirect immuno fluorescence; the two isolates could not be distinguished by these tests, but the tests distinguished them from hsv-1 strain 71-15 and hsv-2 strain 333. the viruses were ... | 1982 | 6292427 |
| expression of cloned herpesvirus genes. i. detection of nuclear antigens from herpes simplex virus type 2 inverted repeat regions in transfected mouse cells. | three different recombinant plasmids containing the entire 15-kilobase l and s inverted repeat sequence of herpes simplex virus type 2 dna have been introduced into cultured ltk- or bsc cells by both the calcium and deae-dextran transfection procedures. in each case, after 24 h approximately 1% of the cells gave strongly positive nuclear staining when assayed by immunofluorescence with hyperimmune antisera made against early and immediate-early infected-cell polypeptides. the nuclear fluorescenc ... | 1982 | 6292452 |
| glycoproteins of herpes simplex virus type 2 as defined by monoclonal antibodies. | we used monoclonal antibodies reacting with glycoproteins specified by herpes simplex virus type 2 (hsv-2) to characterize the individual antigens in terms of structure, processing, and kinetics of synthesis in bhk or vero infected cells. our results provided a direct demonstration of the structural identity of the ga and gb proteins of hsv-2 as well as confirmation of the existence of type-specific and type-common domains within the gd molecule. they also show that, with the exception of gc, pr ... | 1982 | 6292496 |
| herpes simplex virus glycoprotein ga/b: evidence that the infected vero cell products comap and arise by proteolysis. | we recently reported (pereira et al., proc. natl. acad. sci. u.s.a. 78:5202-5206, 1981) that herpes simplex virus 1 and 2 glycoproteins, previously designated ga and gb, could not be differentiated by a bank of independently derived type-specific and type-common monoclonal antibodies. we also reported that from lysates of infected vero cells, all but one monoclonal antibody precipitated ga/b glycoproteins which had faster electrophoretic mobility than the corresponding infected hep-2 cell glycop ... | 1982 | 6292507 |
| unusual serologic response to two patients to an early antigen of herpes simplex virus type 2. | two patients infected with herpes simplex virus type 2 (hsv-2) who were free of recurrences over a 13-14-month period had an unusually high titer (greater than 1:48) of complement-fixing antibody to the early antigen (ag-4) of hsv-2. their response was also unusual in that it was an igg complement-fixing antibody rather than igm, which normally is found in patients with hsv-2 infection. the antibody was also present 13-14 months after the episode of hsv-2 disease, whereas in other patients, the ... | 1982 | 6293106 |

| comparison of the in vitro and in vivo anti-herpes activities of 1-beta-d-arabinofuranosylthymine and its 5'-monophosphate. | in vitro and in vivo anti-herpes activities of 1-beta-d-arabinofuranosylthymine 5'-monophosphate (ara-tmp) were compared with those of 1-beta-d-arabinofuranosylthymine (ara-t). on a molar basis ara-tmp was almost as active as ara-t against six strains of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) as monitored by a cytopathogenicity-inhibition and a plaque reduction assay in human embryonic lung fibroblast cells. when tested against experimental encephalitis in mice inoculated intrace ... | 1982 | 6293376 |
| comparison of restriction endonuclease profiles of dna from local herpes simplex virus type 2 (hsv-2) strains. | comparisons of restriction endonuclease profiles of dna isolated from nine genital hsv-2 strains isolated from 1973 to 1981 were made using six restriction endonucleases (bgl ii, hind iii, xba 1, eco ri, bam hi and hpa i). the only variation detected in the dna profiles was found with eco ri and bam hi, and in each case all the isolates could be classified into two groups. the difference between the two eco ri groups could be accounted for by the absence of an eco ri cleavage site from the hsv d ... | 1982 | 6293436 |
| chemical interactions with herpes simplex type 2 virus: enhancement of transformation by selected chemical carcinogens and pro-carcinogens. | quantitative assays for the morphological transformation of 3t3 swiss mouse cells by herpes simplex type 2 virus (hsv-2) were employed to examine the effect on cell transformation of chemical carcinogens and pro-carcinogens. the carcinogens tested were n-methyl-n'-nitro-n-nitrosoguanidine, quinacrine mustard, n-nitrosomethyl urea, urethane, and benzene. the pro-carcinogens tested were n-nitrosodimethylamine, 3-methylcholanthrene, benzo[a]pyrene, and p-dimethylaminoazobenzene. exposure of the cel ... | 1982 | 6293737 |
| detection by rna blot hybridization of rna sequences homologous to the bglii-n fragment of herpes simplex virus type 2 dna. | rna species, extracted at the time of peak synthesis of the alpha, beta, and gamma classes of herpes simplex virus polypeptides from lytically infected vero cells, were examined for homology to the bglii-n fragment (map units 0.58 to 0.63) of herpes simplex virus type 2 dna. by using northern blot analysis, two major and several minor polyadenylated rna species showed homology to the bglii-n fragment at times corresponding to the maximum synthesis of the beta (7 h postinfection) and gamma (12 h ... | 1982 | 6294326 |
| [acquired immunologic deficiency syndrome, opportunistic infections and homosexuality. presentation of 3 cases studied in switzerland]. | three cases of multiple opportunistic infections in previously healthy homosexual males were observed in 3 different university hospitals in switzerland. two of the patients died. infections were multiple, with p. carinii pneumonia (3 cases), chronic mucocutaneous ulcers probably due to herpes simplex virus (2 cases), mucosal candidiasis (2 cases) and disseminated infections due to cytomegalovirus (1 case) and mycobacterium avium (1 case). all patients had depressed cellular immunity with marked ... | 1982 | 6294820 |

| characterization of an herpes simplex virus type 2 mutant, which is resistant to acycloguanosine and causes fusion of bsc1 cells. | a mutant of herpes simplex virus type 2, which induces low levels of thymidine-kinase activity in infected bsc1 cells and consequently able to grow in the presence of acycloguanosine, was isolated. this mutant has also been shown to cause fusion of bsc1 cells. in bsc1 cells, co-infected with the wild-type strain and the mutant, the yield of each of the two viruses was normal but the rounding and aggregation of cells observed, resembled that found in wild-type infected cultures. when the mixed in ... | 1982 | 6299232 |
| imide derivatives of 3-nitro-1.8-naphthalic acid: their inhibitory activity against dna viruses. | the antiviral action of a new drug, 5-amino-2-(dimethylaminoethyl)-benzo-[de]-isoquinolin-1.3-dione has been studied against herpes simplex type 2 (hsv-2) and adenovirus type 5 (ad-5) grown in vero cells. the concentration of the drug which gives a 5 log10 reduction in virus titer was 4 micrograms/ml (maximum tolerated concentration) for hsv-2. the anti-hsv-2 activity of this compound was one log. more powerful than that of iododeoxyuridine (idu). at this concentration the drug shows virucidal a ... | 1982 | 6299235 |
| abortive infection of neural cells by herpes simplex virus type 2. | the nature of the refractoriness of c6 rat glioma cells to herpes simplex virus type 2 (hsv-2) was examined. infection of c6 cells with hsv-2 results in low virus yields, not exceeding the input virus. although virus growth studies suggested a restricted cycle of virus replication, synthesis of hsv-2 dna and hsv-2-specific antigens could not be detected. in addition, hsv-2 yields in c6 cells were unaffected by interferon, cycloheximide, tunicamycin, actinomycin d and cytosine arabinoside. howeve ... | 1982 | 6299239 |
| modification of herpes 2-transformed cell-induced tumors in mice fed different sources of protein, fat and carbohydrate. | the effects of different sources of protein (milk, soy, wheat, fish and beef), fat (corn oil and butter), and carbohydrate (dextrin and sucrose) on tumor development and on spleen characteristics were investigated in balb/c mice injected subcutaneously with 5 x 10(5) herpes simplex virus type 2-transformed cells (h238 cells). low or high levels of protein and fat were used. several weeks post-injection results indicated that a high level of fat significantly enhanced tumor incidence. a high fat ... | 1982 | 6299511 |
| different weekly changes in immune response in virus-transformed cell-injected mice fed two different diets. | changes in tumor development and in certain immune responses were investigated at 7-weekly intervals after subcutaneous injection of 5 x 10(5) herpes simplex virus type 2-transformed cells (h238 cells) into male balb/c mice fed 2 different diets. one diet contained 11% casein and 5% fat while the other had 11% supplemented wheat gluten and 30% fat. weanling mice (140/group) were fed one or the other of the diets for 12 weeks before injection and subsequent testing of 15 injected and 5 non-inject ... | 1982 | 6299512 |
| herpes virus-related antigens in herpes simplex virus type 2-transformed cells in the course of cervical carcinoma. | anticomplement immunofluorescence (acif) technique was applied to herpes simplex virus type 2 (hsv-2)-transformed cells (333-8-9) and to cells lytically infected with hsv-2 in sera from women with cervical carcinoma. there was a correlation between the positive results with both types of cells. long-term survivors suffering from cervical cancer showed a high percentage of positive immunofluorescence (if) reactions in hsv-2 transformed cells (77%) as well as in cells lytically infected with hsv-2 ... | 1982 | 6299751 |
| use of monoclonal antibodies to hsv-1 and hsv-2 for serological analysis of the viral glycoproteins. | herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) specify four major glycoproteins designated ga/gb, gc, gd and ge. type-specific and cross-reacting monoclonal antibodies to the viral glycoproteins have been used to probe their antigenic determinants. our studies show the following: (i) type-specific monoclonal antibodies are suitable reagents for serotyping isolates. discriminating monoclonal antibodies distinguish antigenic variants among the strains of each serotype. (ii) glycoproteins ga ... | 1982 | 6299824 |
| development of sensitive and enzyme-linked immunoassays for herpesvirus antigens and some applications. | sensitive enzyme-linked immunoassays for herpes simplex virus (hsv), cytomegalovirus (cmv) and varicella-zoster virus (vzv) were developed. both a sandwich technique, using antiviral antibodies from two species to detect the antigen, and an inhibition assay where the sample antigen was incubated with one antiserum, could be used. around 4-50 ng of viral antigens (measured as protein content) could be detected. the elisa inhibition technique using type-specific antisera could differentiate betwee ... | 1982 | 6299833 |
| application of molecular genetics to the design of live herpes simplex virus vaccines. | in principle, several avenues for attenuation of herpes simplex viruses (hsv) are now available. these include intermixing of hsv-1 and hsv-2 genes by recombination, altering the regulation of gene expression and the deletion of viral genes not required for replication of the virus in permissive cells in culture. results of analyses of hsv-1 x hsv-2 recombinants and of mutants containing a deletion in a gene expressed early in infection showed a loss of virulence when infected by intracerebral r ... | 1982 | 6299836 |
| herpes simplex virus subunit vaccine: characterization of the virus strain used and testing of the vaccine. | herpes simplex virus type 1 (hsv-1) used for vaccine production was isolated from a nasal recurrent infection and propagated over a limited number of passages in human diploid cells only. it was designated as hsv-1 bw3 and has been characterized by neutralizing antibodies as a typical hsv type 1 strain. in vitro transformation studies performed with this isolate in mouse or hamster cells revealed only very low, if any, transforming capacity. a preparation of hsv-1 bw3 which can be used as seed l ... | 1982 | 6299841 |
| intertypic superinfection of herpes simplex virus in vivo leads to reisolation of latent viruses with newly acquired lymphotropic properties. | the susceptibility of juvenile tupaias to several strains of temperature-sensitive mutants of hsv-1 and 2 was tested. it was found that in all cases the animal survived an infection of 1 x 10(7) pfu of temperature-sensitive mutants which were administered intravenously. in contrast, an infection dose of 1 x 10(3) pfu of wild-type hsv-2 and 1 x 10(2) pfu or hsv-1 was fatal for juvenile tupaias. those animals which had initially been infected with the ts-mutants of hsv-1 and/or 2 were protected ag ... | 1982 | 6299861 |
| the role of herpes simplex virus in cervical and vulvar cancer. | this report extends the association of herpes simplex virus type 2 (hsv2) with cervical cancer to vulvar carcinoma. in addition to seroepidemiologic observations linking prior hsv2 infection to genital cancer, the new evidence involves the neoplasms themselves. biopsies of cervical and vulvar cancers were found to contain hsv2-specified antigens. the virus-induced antigens are nonstructural dna-binding proteins normally present in the nuclei of infected cells; however, in the cancer cells they w ... | 1982 | 6299862 |
| control of expression of the herpes simplex virus-induced deoxypyrimidine triphosphatase in cells infected with mutants of herpes simplex virus types 1 and 2 and intertypic recombinants. | infection of cells with herpes simplex virus type 1 (hsv-1) induces high levels of deoxypyrimidine triphosphatase. the majority of the enzyme activity is found in infected cell nuclei. a similar activity is induced by hsv type 2 (hsv-2) which, in contrast to the hsv-1 enzyme, fractionates to more than 99% in the soluble cytoplasmic extract. of a series of temperature-sensitive mutants of hsv-1 studied, only the immediate-early mutants in complementation group 1-2 (strain 17 mutants tsd and tsk a ... | 1982 | 6128430 |
| detection of rna complementary to herpes-simplex virus in mononuclear cells from patients with behçet's syndrome and recurrent oral ulcers. | viral dna probes were used in in-situ hybridisation to detect the complementary rna in mononuclear cells from the blood of normal subjects and patients with behçet's syndrome and recurrent oral ulcers. hybridisation of 125i-labelled dna probes was detected by means of autoradiography and quantitated with a video image-analysis technique. hybridisation between herpes-simplex virus type 1 (hsv-1) dna and the complementary rna in mononuclear cells was significantly greater in 10 of 20 patients with ... | 1982 | 6129461 |
| confirmation of herpes simplex virus type 2 infections in herpes-like genital lesions by a simple complement-fixation test. | the presence of complement-fixing antibody to an early herpes simplex virus type 2 (hsv-2) antigen (the ag-4 antigen) was correlated with hsv-2 infection in the sera of patients with genital herpes. eighty-eight per cent of sera taken two weeks after clinical diagnosis of a primary or recurrent herpes infection in patients, confirmed to have hsv-2 by virus isolation and typing, contained the anti-ag-4 complement-fixing antibody. none of the patients with genital hsv-1 had the antibody, and only ... | 1982 | 6275941 |
| investigations in the transforming activity of temperature-sensitive mutants of herpes simplex virus. | transformation of rat embryo fibroblast was induced by a temperature-sensitive mutant of herpes simplex virus type 2. transformation was scored using the morphological criterion of focus formation and the cell changes that lead to the final focus are described. virus genome persistence in the transformed cell line was demonstrated by the presence of virus-specific membrane antigens and by the specificity of antibodies elicited in rabbits by inoculation of transformed cells. the cytogenetic analy ... | 1982 | 6280377 |
| antibody-dependent cell-mediated cytotoxicity to herpes simplex virus-transformed cells in the course of cervical carcinoma. | the antibody-dependent cell-mediated cytotoxicity assay was used to determine whether humoral antibodies from women with cervical carcinoma in the presence of normal mononuclear cells could induce cytotoxicity to hamster embryo fibroblasts, originally transformed by herpes simplex virus type 2 (hsv-2) (333-8-9), to a cervical carcinoma cell line (me-180) and to a lung carcinoma cell line (a-549). control groups consisted of 81 age-matched healthy women and 77 patients suffering from malignancies ... | 1982 | 6280493 |
| inhibiting herpes simplex virus type 2 infection in human epithelial cells by gossypol, a potent spermicidal and contraceptive agent. | gossypol, a male contraceptive, has an antifertility effect of 99.9%. it has also been reported to possess antiviral activities, and to inhibit herpes simplex virus infection in mice. dorsett and kerstine found that gossypol inactivated the infectivity of the enveloped virus parainfluenza type 3 and herpes simplex for hep-2 carcinoma cells but had no effect on the infectivity of the nonenveloped poliovirus. the authors studied the effect of gossypol on infection by herpes simplex virus type 2 ... | 1982 | 6277198 |
| neurological involvement in mice after infection with a cold-adapted herpes simplex type 2 virus. | experimental intracerebral infection of 4-week-old mice with the ms strain of herpes simplex virus type 2 or its derivative cold variant was compared. the infectious process was followed in both the brain tissue and the trigeminal ganglia, using hematoxylin and eosin and antigenic tracing with indirect peroxidase-antiperoxidase staining. the wild-type virus elicited a severe meningitis and necrotic lesions by 7 days post-inoculation in the brain. the cold variant produced a mild meningitis and n ... | 1982 | 6279512 |
| typing of herpes simplex virus with type-specific human immunoglobulin m in an indirect immunofluorescence assay. | sera from nine individuals with suspected primary herpes simplex virus type 1 (hsv-1) or type 2 (hsv-2) infection were screened to identify those containing hsv type-specific immunoglobulin m (igm). selected sera were then utilized in an igm-specific indirect immunofluorescent-antibody hsv-typing assay (patent pending). to evaluate the procedure, 29 hsv isolates were grown in cultures of continuous human amnion cells, fixed, and used as substrates for indirect immunofluorescence. determination o ... | 1982 | 6279692 |
| sulphated glycoproteins induced by herpes simplex virus. | bhk cells infected with strain 17 syn+ (hsv-1) or hg52 (hsc-2) incorporated inorganic sulphate into polypeptides which co-migrated on sds-polyacrylamide gels with virus-induced glycoproteins. the major sulphated glycoprotein was glycoprotein e. in addition, less-intense sulphated bands co-migrated with glycoprotein d and hsv-1 glycoprotein a/b/c. sulphate label co-migrating with hsv-2 glycoprotein a/b/c was occasionally observed. we have investigated which sulphated polypeptides are excreted fro ... | 1982 | 6278062 |

| activation of herpes simplex virus (hsv) type 1 genome by temperature-sensitive mutants of hsv type 2. | previous studies have demonstrated that herpes simplex viruses (hsv) type 1 (hsv-1) and type 2 (hsv-2) can be maintained in a repressed form in human embryo lung cells. reducing the incubation temperature or superinfecting with a heterologous herpesvirus, human cytomegalovirus (hcmv), results in activation of virus replication. we now report that superinfection with a partially homologous herpesvirus, hsv-2, also resulted in activation of hsv-1. to minimize excessive synthesis of infectious hsv- ... | 1982 | 6278723 |
| viral receptors on isolated murine and human ependymal cells. | viruses that infect ependyma cause ependymitis in humans and hydrocephalus in experimental animals. we report that reovirus type 1 (which induces hydrocephalus in mice) binds to the surface of isolated human and murine ciliated ependymal cells. with the use of recombinant viral clones, the binding property was mapped to the type 1 viral hemagglutinin, which also determines in vivo the affinity of reovirus type 1 for ependyma. mumps virus, measles virus, parainfluenza type 3, and herpes simplex v ... | 1982 | 6276976 |
| epidemiology of sexually transmitted diseases in the scandinavian countries. | in the scandinavian countries, laws require reporting of the traditional venereal diseases, i.e., gonorrhea, syphilis, lymphogranuloma venereum (lgv), and ulcus molle, or chancroid. incidence figures for these diseases, therefore, are fairly reliable. in the scandinavian countries, lgv and chancroid are rare diseases, and the syphilis incidence has remained low. these three diseases are typically male afflictions. gonorrhea outnumbers the other diseases mentioned and at present has a nearly 1:1 ... | 1982 | 6958011 |
| influenza type a virus-mediated adherence of type 1a group b streptococci to mouse tracheal tissue in vivo. | influenza type a virus-mediated adherence of pathogenic bacteria to the mucosal surface of the respiratory tract may be one of several mechanisms whereby influenza predisposes to bacterial pneumonia. in the present study, we quantified the adherence of intranasally administered type 1a group b streptococci to the tracheal tissue of influenza type a/pr8/34 (honi) virus-infected and mock-infected mice. influenza type a/pr8/34 virus infection effected a 120-fold increase in the adherence of type 1a ... | 1982 | 6754623 |
| treating viral venereal infections with the co2 laser. | viral venereal infections caused by herpes simplex virus 2 and papillomavirus (wart) are epidemic diseases in the united states. unfortunately, these two infections have eluded conventional therapy to date. therefore, 306 women were treated for viral venereal diseases with the co2 laser. two hundred twenty-eight patients were treated for condyloma acuminatum and 78 for genital herpes. all the patients who underwent treatment for herpes were enrolled in an investigative protocol. since the viral ... | 1982 | 6819358 |
| immunity to herpes simplex virus type 2. iv. impaired lymphokine production during recrudescence correlates with an imbalance in t lymphocyte subsets. | cell-mediated immunity (cmi) to herpes simplex virus type 2 (hsv-2) was studied in patients with recurrent disease. peripheral blood lymphocytes (pbl) obtained during recrudescence (0 to 3 days post-onset of lesion), convalescence (4 to 14 days), and quiescence (greater than 14 days), which were cultured in vitro in the presence of uv-inactivated hsv-2 (g) antigen, demonstrated similar, virus-specific lymphoproliferative responses. however, the production of the lymphokine, leukocyte migration-i ... | 1982 | 7045224 |
| spinal cord and optic nerve demyelination in experimental herpes simplex virus type 2 infection. | to produce a model of central nervous system (cns) demyelination, three strains of herpes simplex virus type 2 (hsv-2) were injected intracerebrally into swiss-webster outbred mice. animals developed pupillary abnormalities and leg weakness and, by light and electron microscopy, had focal lesions of primary demyelination in optic nerves and spinal cords. oligodendrocytes and astrocytes in these lesions contained herpesvirus. both mouse age and virus dose were important determinants of the rate a ... | 1982 | 7077361 |
| optimal treatment of herpes simplex virus encephalitis in mice with oral acyclovir. | the effect of oral or intraperitoneal administration of acyclovir was evaluated in four experimental models of herpes simplex virus (hsv) encephalitis in mice. mice were inoculated with hsv-1 or hsv-2 intracerebrally or with hsv-2 intranasally, intraperitoneally, or intravaginally. with all four routes of inoculation, oral acyclovir therapy significantly reduced mortality when started as late as 72 to 96 hours after viral challenge. intraperitoneal acyclovir was not effective in protecting mice ... | 1982 | 7102699 |
| virus-specific antibodies in sera from patients with genital herpes simplex virus infection. | virus-specific antibodies against a number of herpes simplex virus type 2 antigens were determined by radioimmunoprecipitation assays in sequential serum samples obtained from 12 patients with initial genital herpes simplex virus infection. the progressive appearance of antibodies to virus-specific antigens was observed; antibodies against a 130,000-molecular-weight glycoprotein complex appeared first, followed by antibodies against the major nucleocapsid polypeptide and then antibodies against ... | 1982 | 7118244 |
| herpes simplex type 2 virus encephalitis presenting as psychosis. | the current literature recognizes two antigenic types of herpes simplex virus, type 1 and 2. type 1 is the most common cause of sporadic necrotizing encephalitis in the united states, with a mortality rate of 30 to 70 percent, and leaves various neurologic sequelae in the survivors. herpes simplex virus type 2 had been recognized as an etiologic agent in fatal infections in neonates and a mild meningitis in adults, but its role in encephalitis in adults is less well known. we report a case of he ... | 1982 | 7124772 |
| lethal encephalitis and non-lethal multifocal central nervous system demyelination in herpes simplex virus type 2 infections in mice. | six-week-old swiss-webster mice were infected intracerebrally with a low dose of herpes simplex virus type 2 (hsv-2) and were studied by pathological, virological and immunological methods. one third of mice developed severe neurological disease and died during the first 31/2 weeks of infection, while the remaining two thirds survived this acute stage with relatively minor neurological signs. these survivors had multifocal demyelinative white-matter lesions in the cns, and gray-matter lesions, i ... | 1982 | 7150512 |
| aseptic meningitis and herpes simplex proctitis. a case report. | a male homosexual patient developed an aseptic meningitis during the course of acute ano-proctitis due to herpes simplex virus type 2 (hsv-2). aseptic meningitis (sometimes proved to be due to hsv-2) has been associated with genital but not with anal herpes. this sexually transmissible virus should be considered when patients with aseptic meningitis are investigated. | 1982 | 7198922 |
