| parenterally transmitted non-a, non-b hepatitis: an epidemic reassessed. | in 1972 a nonsocomial outbreak of parenterally transmitted hepatitis affected both marrow transplant patients and normal platelet donors in an oncology unit. because of the characteristics of the clinical illness, the incubation period of 27 days, and the effect of immune serum globulin on the clinical illness, the outbreak was attributed to hepatitis a; there was no serologic evidence of either hepatitis b virus or cytomegalovirus infection. stored serums from this outbreak were re-examined by ... | 1977 | 195506 |
| the viral etiology of cancer: a realistic approach. | the etiology of cancer resembles that of many other diseases in that multiple factors may be required. because of this, the role or viruses in the etiology of human cancers is especially difficult to assess. when animal tumor systems were used as models, the roles of various predisposing characteristics in virus oncogenesis were elucidated. extrapolation of these findings to the human diseases suggests the importance of genetics, age, hormones, immune competence, and stress in determining suscep ... | 1977 | 195710 |
| development of cell-mediated immunity to epstein-barr herpesvirus in infectious mononucleosis as shown by leukocyte migration inhibition. | eight patients with infectious mononucleosis, aged between 8 and 24, were studied for cell-mediated immunity by the in vitro leukocyte migration inhibition test at acute and convalescent stages. follow-up studies were also carried out at up to 4 months after clinical illness. cell-mediated immunity to epstein-barr virus (ebv) in the peripheral leukocytes from these patients was absent or incipient in all cases during the acute phase, although it was present in lymphocytes from a biopsied lymph n ... | 1977 | 195902 |
| epstein-barr virus viral capsid antigen titer by immunofluorescence with microplates: new semiautomated method based on the microtiter system. | a semiautomated method of an indirect immunofluorescence technique for the titration of antibodies directed against viral capsid antigens of epstein-barr virus has been developed with microtiter system units. by this method, a technician is able to titrate some hundred samples daily. the technique is safe, easy, and reproducible. the various procedures are described, and the sensitivity of the test is discussed. | 1977 | 195981 |
| dna of epstein-barr virus. ii. comparison of the molecular weights of restriction endonuclease fragments of the dna of epstein-barr virus strains and identification of end fragments of the b95-8 strain. | incubation of the dna of the b95-8 strain of epstein-barr virus [ebv (b95-8) dna] with ecori, hsu i, sal i, or kpn i restriction endonuclease yielded 8 to 15 fragments separable on 0.4% agarose gels and ranging in molecular weight from less than 1 to more than 30 x 10(6). bam i and bgl ii yielded fragments smaller than 11 x 10(6). preincubation of ebv (b95-8) dna with lambda exonuclease resulted in a decrease in the hsu i a and sal i a and d fragments, indicating that these fragments are positio ... | 1977 | 196117 |

| enhanced oncogenic behavior of human and mouse cells after cellular hybridization with burkitt tumor cells. | studies were made of the expression of the epstein-barr virus (ebv) in somatic hybrids of burkitt tumor cells and human or mouse cells to determine whether ebv genetic information associated with the capacity to transform leukocytes of human and non-human primates could be maintained and expressed in nonlymphoblastoid cells. data obtained thus far suggest that at least one characteristic associated with cellular transformation (loss of contact inhibition) is expressed only in nonlymphoblastoid c ... | 1977 | 196293 |

| spontaneous and induced patterns of the epstein-barr virus (ebv) cycle in a new set of somatic cell hybrids. | a somatic cell hybrid line and its subclones obtained by fusing two burkitt lymphoma lines (raji and namalwa) were examined for the expression of ebv-specific antigens both spontaneously and after induction. the hybrids retained spontaneous early antigen (ea) production at the level characteristic of raji. similarly the more permissive raji pattern dominated the induction of ea by iudr treatment or p3hr-1 virus superinfection. these findings accord with our previous results on independently deri ... | 1977 | 196751 |
| [cytotoxicity of human t-lymphocytes sensitized by epstein-barr virus. role of hla antigens at the surface of target cells infected by the virus]. | peripheral t-lymphocytes from patients with infectious mononucleosis are cytotoxic towards target cells from epstein-barr virus-genome carrying human lumphoblastoid lines. thus, these t-cells appear to be sensitized to viral coded determinants. daudi cells, that carry ebv-genome, but lack hla antigens are resistant to specific cytolysis in this model. these results suggest direct hla involvement in the target structure recognized by birus-sensitized cytolytic t-lymphocytes in human. | 1977 | 196780 |
| antibody-dependent cellular cytotoxicity (adcc) against epstein-barr virus-determined antigens ii. induction of adcc by fc-fc receptor bridging. | four different methods to test antibody-dependent cellular cytotoxicity (adcc) against epstein-barr virus (ebv) determined antigens were analysed. it was found that optimal adcc was obtained if viral antigens were present during the cytotoxicity reaction and that killing probably was mediated by ebv-related immune-complexes forming fc-fc receptor bridges between fc receptor-bearing effector cells and fc receptor-bearing target cells. only lymphoid target cells with a high expression of fc recept ... | 1977 | 196801 |
| search for inhibitors against herpes simplex virus type-i in cell extracts derived from human lymphoblastoid cell lines. | cell extracts obtained from kb cells and 5 human lymphoblastoid cell lines including 2 from burkitt's lymphoma (p3hr-1 and raji), one each from nasopharyngeal carcinoma (no.223), acute lymphatic leukemia (molt-4) and a healthy person (nc-37) were tested for their inhibitory effects on the growth of herpes simplex virus type-1 (hsv-1) in green monkey kidney (gmk) cells by the plaque titration method. the relationship between the production of hsv-1 inhibitors and the degree of epstein-barr virus ... | 1977 | 196817 |

| search for infectious epstein-barr virus-releasing cell lines, with particular reference to a new producer line, nhad-60. | in a search for infectious epstein-barr virus (ebv)-producer cell sources, 36 ebv genome-carrying lymphoblastoid cell lines originating from various sources in japan were screened. three cell lines derived from different sources were found to release infectious ebv into the culture fluid. ebv from these 3 lines possessed leucocyte-transformation activity but did not induce early antigen formation. one of the three lines, nhad-60, originated from an adenoid tissue; it released a relatively large ... | 1977 | 196968 |
| infectious mononucleosis: recognition and management. | differentiation from other common viral infections depends on a triad of clinical, hematologic, and serologic determinations. a distinctive feature is that while a number of circulating immunoglobulins are often detected, only paul-bunnell antibodies, found in 75% of cases, are specific for im. symptomatic care only is indicated for most patients, though severe cases or complications may require antibiotics or corticosteroids. | 1977 | 196996 |
| human lymphoblastoid cell lines derived from individuals without lymphoproliferative disease contain the same latent forms of epstein-barr virus dna as those found in tumor cells. | the physical state of the intracellular epstein-barr virus dna was characterized in four human lymphoblastoid cell lines, f-265, nc-37, u-303 l, and pg-1, derived from individuals without lymphoproliferative disease. for comparison, a previously investigated burkitt lymphoma line, raji, and a more recently established cell line of that origin, rael, were also studied. the techniques employed were cscl density gradient centrifugation, glycerol gradient centrifugation, and ethidium bromide-cscl de ... | 1977 | 197024 |
| transformation of lymphocytes by herpesvirus papio. | cotton-topped (ct) or white-lipped (wl) marmoset lymphocytes were transformed in vitro with herpesvirus papio (hvp) into permanently growing lymphoblastoid cell lines (lcl). five of 9 hvp-transformed ct cell lines contained cells with antigens reacting with antibodies to epstein-barr virus (ebv) capsid antigen (vca) and/or to ebv-induced early antigens (ea). none of 12 wl lcl revealed such antigen-producing cells. cells from both groups of cultures failed to react with antibodies to the ebv-spec ... | 1977 | 197025 |
| productive epstein-barr viral infection of the human lymphoblastoid cell line 6410 with release of early antigen inducing and transforming virus. | the human lymphoblastoid cell line 6410 was superinfected with p3hr-1 derived epstein-barr virus. subsequent to the first cycle of infection, characterized by early (ea) and virus capsid (vca) antigen synthesis, the culture, designated 6410-ebv, continued to synthesize vca. further immunofluorescence and electron microscopic examination over 18-24 months showed the 6410-ebv culture to be productively infected with ebv. virus was recovered, in quantity, from the culture fluids and assayed for abi ... | 1977 | 197026 |
| clonal transformation of adult human leukocytes by epstein-barr virus. | we have developed a clonal transformation assay for epstein-barr virus which uses adult human leukocytes as target cells. the target cells were isolated from epstein-barr seronegative donors, and the same donor's cells could be studied repeatedly over long periods of time. when these cells were transformed by epstein-barr virus and had proliferated sufficiently to be studied, they had an average cloning efficiency of 3%. assuming this average cloning efficiency obtains at the onset of transforma ... | 1977 | 197258 |

| the epidemiology of oral cavity, pharyngeal and esophageal cancer outside of north america and western europe. | geographical variations in the incidence of oral cavity, pharyngeal, and esophageal cancer were studied, with special reference to rates in countries outside of the united states and western europe. although reporting techniques differ greatly and comparisons must be made with caution, significant variations are evident. tracing such differences often reveals possible etiologic factor for these forms of cancer. the roles are discussed of known environmental carcinogens, such as n-nitroso compoun ... | 1977 | 198109 |
| solubilisation of epstein-barr virus (ebv)-associated nuclear antigen from raji cells and chromatin by treatment with various molarities of nacl. | the solubilisation of epstein-barr virus (ebv)-associated nuclear antigen (ebna) by treatment with various molarities of nacl was investigated using the 125i--igg absorption assay. ninety percent of the antigenic activity detected using the 125i--igg absorption assay was insoluble at 0.15 m nacl. it could be rendered soluble by treatment with 2.0 m nacl, but reprecipitated upon return to 0.15 m nacl. ebna was partially extracted from raji chromatin by treatment with 0.35 m nacl. the efficiency o ... | 1977 | 198113 |

| infectious mononucleosis and fatal myocarditis. | mycocarditis is an uncommon manifestation and, very rarely, a lethal complication of infectious mononucleosis. a 14-year-old girl initially had exudative pharyngitis and splenomegaly and developed refractory ventricular fibrillation. the diagnosis of infectious mononucleosis was confirmed by both a strongly positive heterophil antibody test and a high titer of epstein-barr virus. pathologic studies demonstrated extensive histiocytic and lypmhocytic infiltration of the myocardium. | 1977 | 198186 |
| epstein-barr herpesvirus infection: inhibition by immunologically induced mediators with interferon-like properties. | when sensitized leukocytes were re-exposed to ebv antigen or to tuberculin-purified protein derivatives, they produced lymphokines, including the migration inhibition factor, which inhibited the migration of guinea-pig peritoneal exudate cells, and other lymphokines with the characteristics of interferon, which inhibited ebv-induced transformation and ebv superinfection of target cells. unsensitized leucocytes from sero-negative adults and from neonates did not produce lymphokines when challenge ... | 1977 | 198380 |
| comparative studies on immunity to ebv-associated antigens in npc patients in north america, tunisia, france and hong kong. | this study compared the relative antibody titers to ebv-related antigens in patients with nasopharyngeal carcinoma (npc) and controls from a high-incidence (hong kong), an intermediate incidence (tunisia), and two low-incidence (france, north america) areas to determine which of several ebv antibodies best differentiated npc patients from controls. antibodies measured include anti-virus capsid antigen (vca), anti-early antigen (ea), anti-soluble antigen by complement-fixation (cf) and antibody-d ... | 1977 | 198381 |
| membrane receptor stripping confirms the association between ebv receptors and complement receptors on the surface of human b lymphoma lines. | complement (c3) receptors, ebv receptors, fc receptors, membrane igm and beta2microglobulin (beta 2m) were individually stripped from the surface of human b lymphoma lines. the cells were subsequently tested for their ability to absorb infectious eb virus. stripping of fc receptors, igm and beta2m did not reduce ebv absorption. stripping of either ebv receptors or c3 receptors eliminated or drastically reduced ebv-absorptive capacity. the results confirm the distinctive association between ebv r ... | 1977 | 198382 |

| prospective study of prevalence, incidence, and source of herpesvirus infections in patients with renal allografts. | the prevalence, incidence, and source of infections with different types of herpesviruses were determined prospectively for 25 persons undergoing hemodialysis, 30 allograft recipients, and 16 kidney donors. the prevalence of prior infections with cytomegalovirus (cmv), herpes simplex virus (hsv), and epstein-barr virus (ebv) was high (72%-100%) and was similar for healthy persons and those with renal failure. the incidence of infections in patients undergoing hemodialysis was no greater than tha ... | 1977 | 198488 |
| detection of soluble antigen of epstein-barr virus by the enzyme-linked immunosorbent assay. | the enzym-linked immunosorbent assay (elisa) was compared with the microcomplement-fixation test for sensitivity and reliability in detection of antibody to soluble antigen of epstein-barr virus. elisa was found to be more sensitive (up to 160 times more antibody) in detecting levels of antibody than the complement-fixation assay. the elisa test was shown also to be comparably reliable to the complement-fixation assay in detecting immunity to this antigen; only one false-positive response was fo ... | 1977 | 198494 |
| some factors affecting the expression of epstein-barr virus-associated membrane antigens. | the effect of two factors, l-arginine concentration and phytohemagglutinin (pha) stimulation, on the expression of epstein-barr virus (ebv)-associated membrane antigens (ma) was evaluated. an ebv-producer cell line, av-1, was cultivated in eagle's basal medium with earle's salts, supplemented with various l-arginine concentrations ranging from 0.0 to 20.0 mm. in most of the l-arginine concentrations, the number of cells expressing ma decreased within the first 24 hours. this decrease was followe ... | 1977 | 198561 |
| epstein-barr virus and nasopharyngeal carcinoma: is there an etiologic relationship? | antibody titers to all the epstein-barr virus (ebv)-related antigens were significant elevated (p less than 0.001) in patients with nasopharyngeal carcinoma (npc) compared with those of controls. ebv, early antigen, and anti-diffuse titers of chinese-american and black patients with npc were higher than those of white patients with npc. epstein-barr viral capsid antigen antibody titers were elevated in white patients with squamous cell carcinoma of the pharynx, regardless of subsite. these resul ... | 1977 | 198562 |
| [factors involved in the development of human tumors using the epstein-barr virus as an example (author's transl)]. | several viruses induce tumors in animals under experimental or natural conditions. it is likely therefore that some human malignancies are also caused by viruses. proof of this hypothesis can be provided only by indirect evidence based on the following criteria: (1) detection of viral antigens or viral genetic information in a given tumor; (2) transformation of normal human cells by the virus in tissue culture; (3) induction of tumors in animals by the virus; and (4) demonstration of enhanced ti ... | 1977 | 198603 |
| variable phenotypic expression of an x-linked recessive lymphoproliferative syndrome. | investigation of a family with cancer in boys revealed that at least 20 males had the x-linked recessive lymphoproliferative syndrome. a variety of phenotypes occurred: aproliferative phenotypes consisted of aplastic anemia, agranulocytosis or acquired hypogammaglobulinemia; and proliferative phenotypes of b cells included disorders associated with the epstein-barr virus, american burkitt's lymphoma, immunoblastic sarcoma of b cells, fatal infectious mononucleosis or plasmacytoma. the lymphoprol ... | 1977 | 198660 |

| establishment of an epstein-barr virus-negative b-cell lymphoma line from a japanese burkitt's lymphoma and its serial passage in hamsters. | an epstein-barr virus (ebv)-negative lymphoma line (jbl) was established in vitro from pleural effusion of an ebv-seropositive 29-year-old japanese female with burkitt's lymphoma. jbl cells as well as her original lymphoma cells bore monoclonal surface igm with lambda light chains. the jbl line grew in single cell suspension with a doubling time of 30 hours. attempts were made to serially transplant jbl cells in antilymphocyte serum-treated newborn hamsters; intraperitoneal implantation of 1-3 x ... | 1977 | 201360 |
| multiple childhood osteosarcomas in an american indian family with erythroid macrocytosis and skeletal anomalies. | three of nine children of possibly consanguineous american indian parents developed typical osteosarcoma in a 2-year period. etiologic investigations detected limb anomalies and elevated mean corpuscular volumes (98--109 micrometer3) in the surviving tumor patient, several of her sibs, and her father. limb anomalies included simple clinodactyly with brachymesophalangy, absence of one digital ray of the foot, and bilateral radioulnar synostosis. the red cell macrocytosis was not accompanied by an ... | 1977 | 201363 |
| transfer factor therapy in ataxia--telangiectasia. | the effects of weekly doses of transfer factor in four patients with ataxia--telangiectasia were investigated following a total course of 2 months therapy. transfer factor administration showed no influence on the absolute lymphocyte counts, t-cell rosettes or antibody titres to ebv, but it caused conversion of skin-test reactivity and production of mif to various antigens. there was a dissociation in blastic transformation response, the skin-test responses and mif production. serum interferon l ... | 1977 | 201409 |
| early acquisition of cytomegalovirus and epstein-barr virus antibody in several isolated melanesian populations. | significant differences among diverse human populations have been found in the seroepidemiology of cytomegalovirus (cmv) and epstein-barr virus (ebv). the present report documents a very high rate of early acquisition of antibody to cmv and ebv among three remote populations living in the eastern highlands of papua new guinea, the solomon islands, and the new hebrides, respectively. these three genetically distinct populations, living in widely different ecologies and social settings, each had t ... | 1977 | 193397 |
| herpesvirus group antibodies in children with hodgkin's disease. | during the period of three years ((1972-1974), serum samples from 60 patients (children and adolescents) with lympho-hematopoietic system diseases were examined for antibodies to all four human herpesviruses. among these were 26 active hodgkin's disease (ahd) patients and 6 hd patients with a minimum five years' remission. simultaneously matched controls (age, sex) of ahd patients were examined. antibody levels against the viral capsid antigen of epstein-barr virus (ebv/vca) in ahd patients were ... | 1977 | 193463 |
| possible transformation of nasopharyngeal epithelial cells in culture with epstein-barr virus from b95-8 cells. | explants of fresh biopsy specimens from non-neoplastic nasopharyngeal (np) mucosa, nasopharyngeal carcinoma (npc), other tumours (ot) of the head and neck and freshly removed tonsils were treated with an epstein-barr virus (ebv) preparation from b95-8 cells and cultured. the mainly epitheloid outgrowths from these infected explants were then compared with those from their respective uninfected controls at 14 days. growth stimulation occurred with a significantly higher frequency, and the degree ... | 1977 | 193548 |
| cell surface markers on epithelial-burkitt hybrid cells superinfected with epstein-barr virus. | attempts were made to superinfect two epithelial-burkitt hybrid cell lines, designated d98/hr-1 and d98/raji, with epstein-barr virus (ebv) and to investigate the expression of some cell surfacr markers including histocompatibility antigens, and the presence of b-cell markers, such as receptors for the third complement component and for monkey red blood cells. successful superinfection of d98/hr-1 cells with ebv was made evident by the expression of early antigen and, to a lesser extent, virus c ... | 1977 | 193641 |
| smooth muscle antibody in burkitt's lymphoma and in nasopharyngeal carcinoma. | smooth muscle antibodies (sma) with specificity for actin, were found with a higher frequency in sera from burkitt's lymphoma (bl) and nasopharyngeal carcinoma (npc) patients than in sera from matched controls. no correlation could be found between sma and anti-epstein-barr virus (ebv) antibody titres. there was no parallelism, in individual sera, between the finding of sma and the occurrence of cold lymphocytotoxins, aother antibody activity found with an abnormally high frequency among bl and ... | 1977 | 193662 |
| inhibition of the in vitro outgrowth of epstein-barr virus-transformed lymphocytes by thymus-dependent lymphocytes from infectious mononucleosis patients. | known numbers of thymus-dependent (t) lymphocytes, obtained by positive selection from the blood of acute infectious mononucleosis (im) patients and from control donors, were added to target cultures of foetal mononuclear cells within 0-7 days of exposure of the target cells to one of a range of doses of epstein-barr (eb) virus. the subsequent outgrowth of virus-transformed foetal cells was markedly inhibited by the presence in the cultures of im-derived t cells, whilst similar numbers of t cell ... | 1977 | 193663 |
| neutralizing ebv-specific iga in throat washings of nasopharyngeal carcinoma (npc) patients. | throat washings from 26 nasopharyngeal carcinoma (npc) patients from hong kong and tunisia were studied for the presence of transforming ebv. only six (23%) were found positive which led to the hypothesis of a neutralizing factor in such salivas. the search for ebv-specific antibodies showed that npc saliva contained neutralizing vca and ea iga (54 and 27% respectively) and vca and ea igg (73 and 54% respectively). both transforming and non-transforming throat washings contained virus particles ... | 1977 | 193801 |
