| immunovirologic assessment of american patients with nasopharyngeal carcinoma and occult primary tumors. | the epstein-barr virus (ebv) is closely associated with nasopharyngeal carcinoma, suggesting an etiologic relationship. we have under-taken studies (1) to quantitate the relationship between antibody titers to ebv-associated antigens and nasopharyngeal carcinoma in american patients since most of the patients in previous studies were of either asian or african descent and (2) to determine the relationship between antibody titers and the clinical course of the disease. sera from patients with pri ... | 1978 | 224361 |

| infectious mononucleosis test performance on cap survey specimens. | the participant performances on 1977 and 1978 infectious mononucleosis survey specimens are tabulated. the various methods utilized gave similar results on negative specimens. commercial reagent kits incorporating differential absorption performed somewhat better on positive specimens than kits without differential absorption. many of the commercial reagent kits performed very poorly on the false postitive specimen. | 1979 | 224693 |
| etiology of liver disease in renal-transplant patients. | the etiology of 72 episodes of liver disease that developed in 62 of 162 renal-transplant recipients was evaluated. infection with hepatitis b virus was a minor problem, and none of our patients had evidence of infection with hepatitis a. cytomegalovirus infection was ubiquitous in the population and probably accounted for many episodes of acute liver disease. this agent's role in causing chronic hepatitis is less secure. infections with other viruses including epstein-barr virus, adenovirus, an ... | 1979 | 224742 |

| guillain-barré syndrome associated with epstein-barr virus in a cytomegalovirus-negative patient. | epstein-barr virus and cytomegalovirus have both been associated with guillain-barré syndrome after antibody investigations in several patients. in the teenage female patient in this present report, guillain-barré syndrome following infectious mononucleosis was associated with sero-conversion against epstein-barr virus but not cytomegalovirus. the findings are consistent with the hypothesis that epstein-barr virus might be an etiological agent for the guillain-barré syndrome and that infection w ... | 1979 | 230116 |
| eb virus-specific iga in serum of patients with infectious mononucleosis and of healthy people of different ages. | the following sera were tested for eb virus-specific iga: serial sera from 61 cases of infectious mononucleosis (im) and from 195 ebv igg positive healthy students; single sera from each of 1469 persons of different ages, 63 cases of untreated hodgkin's disease, and 22 neonates. ebv specific iga was found in the sera from 88% of cases of im, from 18.5% of ebv igg positive healthy students, and in 13.5% of repeat samples from the same students three years later. the incidence of ebv iga varied fr ... | 1979 | 230203 |
| mode of integration of epstein-barr virus genome into host dna in burkitt lymphoma cells. | the ebv dna integrated into the host genome from cell of an african burkitt lymphoma biopsy has been compared to the corresponding fraction of ebv dna from the cell line su-amb-2 which is of american burkitt lymphoma origin. it is shown that while, in the case of the african biopsy, large pieces of ebv dna sequences are integrated into the host dna, much smaller pieces of virus dna are integrated into the dna of the su-amb-2 cells. the possibility that this difference might be related to the fac ... | 1979 | 230297 |

| [enzyme induction by epstein-barr-virus-producing infection of lymphoblastoid cell lines]. | by means of biological in vitro assay collagenolytic activity of normal peripheral lymphocytes was compared to that of ebv-infected lymphoblastoid cell lines: the ebv-producing p3hr1 cells and the non-productive raji cells. while normal lymphocytes and raji cells revealed only traces of activity, significantly increased (p less than 0.001) collagenolytic activity was detected in samples of p3hr1, the cell-free ebv-suspension alone showed no collagenolysis. the described enzymatic activity was fu ... | 1979 | 230436 |

| antibodies to epstein-barr virus-determined antigens in normal subjects and in patients with seropositive rheumatoid arthritis. | prior studies have shown that patients with seropositive rheumatoid arthritis (ra) have an increased frequency of precipitating antibody against a nuclear antigen, the ra nuclear antigen, detected in human b lymphoblastoid cell lines infected by epstein-barr virus. the present investigations demonstrate that patients with seropositive ra also have specifically elevated titers of antibodies to another, better-characterized epstein-barr virus-associated b cell antigen, the epstein-barr nuclear ant ... | 1979 | 230491 |
| human cell lines containing epstein-barr virus but distinct from the common b cell lymphoblastoid lines. | a group of very similar cell lines was established from peripheral blood or bone marrow of 12 patients with a variety of disorders. the cells in these cell lines were uniform and round in shape. they grew as single-cell suspensions or as aggregates of small numbers of cells in stationary culture. the most striking characteristic of these lines was the lack of cells with surface immunoglobulin or with demonstrable immunoglobulin synthesis. this lack of immunoglobulin synthesis and their special g ... | 1979 | 230517 |

| establishment of anti-tnp antibody-producing human lymphoid lines by preselection for hapten binding followed by ebv transformation. | human lymphoblastoid cell lines that produce specific antibody against the hapten trinitrophenyl (tnp) have been established by selecting tnp-binding human b lymphocytes by tnp-rosetting and ficoll-isopaque separation, followed by epstein-barr virus (ebv) immortalization. derived lines secreted polyclonal anti-tnp antibodies and contained relatively small numbers of specific rosette- and plaque-forming cells against tnp-rbc. following rerosetting with tnp-rbc, the frequency of rosette-forming ce ... | 1979 | 230581 |
| hla-d typing with lymphoblastoid cell lines. vi. rationale and goals of data reduction. | this report documents various characteristics of hla-d typing by mixed leukocyte culture reactions when lymphoblastoid cell lines (lcls) are substituted for peripheral blood lymphocytes as the stimulator cells. it also provides the rationale for designing the computer program described in the subsequent report. in such experiments, each donor to be hla-d typed is stimulated with a panel of 30-50 hla-d homozygous lcls, each defined hla-d allele being represented by several different human homogyg ... | 1979 | 230611 |
| epstein-barr virus infection in polytransfused patients with homozygous beta-thalassaemia. | the frequency of epstein-barr virus (ebv) and hepatitis b virus (hbv) infection has been studied in 149 polytransfused thalassaemic patients and in healthy controls. evidence for ebv infection was based on the detection of antibodies to viral capsid antigen (anti-vca) and for hbv infection on the detection of either hepatitis b surface antigen (hbsag) or hepatitis b surface antibody (anti-hbs). the frequency of anti-vca was not significantly higher in the patients (16.4%) compared to the control ... | 1979 | 230639 |
