Detection of mumps virus antigens in Hodgkin's disease tissues.

Mumps virus antigens were demonstrated in biopsied tissues from Hodgkin's disease patients by indirect immunofluorescence. Impression smears from ten lymph node and two spleen specimens revealed viral antigens in the nucleus, cytoplasm or both. Measles virus antigens were detected in six out of seven Hodgkin's disease tissue (lymph nodes) both in the nucleus and cytoplasm. All tissues tested for the presence of Newcastle disease virus (NDV, an avian paramyxovirus) antigens were negative. Control tissues were obtained from patients with non-Hodgkin's lymphomas, breast cancers, adenocarcinomas and a number of other disease processes. In control tissues mumps antigens were detected in seven out of 31 specimens and measles antigens in nine out of 18 tissues.

Studies on the use of mumps virus for treatment of human cancer.

Purified mumps virus (Urabe strain) was given mainly by intravenous injection to a total of 200 patients with cancer. The only adverse clinical reaction was transient mild fever in about half the patients. The beneficial clinical effects were as follows; decrease or disappearance of ascites and edema of the lower limbs at high rates (26/37 and 4/4, respectively), usually within a week after treatment: decrease or stoppage of cancerous bleeding in 30 of 35 patients: decrease or disappearance of pain in most of the patients: and tumor regression in 26 patients with cancer of the breast, rectum, ileocaecum, thyroid gland, uterus, skin, etc. Histologically, the virus-treatment caused shrinkage of nuclei and vacuolization of the cytoplasma of tumor cells, but the degenerative changes of tumor cells were not so great as those after chemotherapy or radiotherapy. Infiltration of lymphocytes, fibrosis and collagenesis occurred around tumor tissues, where necrosis or exfoliation of tumor cells was frequently observed.

Differences in antibodies to the surface components of mumps virus after immunization with formalin-inactivated and live vaccines.

Military recruits with or without antibodies to mumps virus were immunized with live or formalin-inactivated mumps virus vaccines. Antibodies to the two major surface components of the virus, the hemagglutinin and the hemolysin, were identified separately. Immunization with the live vaccine did not change the humoral immunity in individuals with detectable antibodies. In seronegative recruits immunization with the live vaccine induced an antibody response against both the hemagglutinin and the hemolysin corresponding to the quality of the immune response after natural infection. In contrast, the formalin-inactivated vaccine only induced an antibody response against the hemagglutinin. This effect was found after immunization of both seronegative and seropositive individuals. The latter displayed a selective boosting of titers of hemagglutination-inhibiting antibody. These findings may have relevance for the interpretation of the short-lived immunity after the use of formalin-inactivated mumps vaccine without repeated boosting.

51Chromium-release microassay technique for cell-mediated immunity to mumps virus: correlation with humoral and delayed-type skin hypersensitivity responses.

Lymphocyte-mediated immune responsiveness to mumps virus was studied with use of a 51chromium (51Cr)-release microassay of lymphocytotoxicity to target cells persistently infected with mumps virus. The release of 51Cr from immune cells was found to be virus-specific and reproducible and correlated well with the presence of antibody but not with the magnitude of antibody levels. Delayed-type skin hypersensitivity and specific immune release of 51Cr did not correlate well, which suggests that the two events may be mediated by different populations of cells.

[Biological properties of the mumps virus--behavior in the rct marker].

12 different mumps virus strains or their variations were studied in the rct-marker in dog kidney cell cultures at 32 degree and 39 degree C. The results obtained were compared with those of the T50 marker ascertained earlier revealing considerably coincident data. Changes in culture conditions became clearly evident in both markers. Relations between their behaviour in vitro in vivo are discussed.

[Study of the correlation between neutralization tests and hemagglutination inhibition tests in determinations of mumps virus antibodies].

In order to find out possibilities of wide application of the hemagglutination-inhibition (HI) test for determination of antibody to mumps virus, correlations between neutralization test (NT) and HI test was studied. Antibody to mumps virus was detected by parallel titrations of sera and gamma globulins in HI and NT tests in two experimental series each of which used various modifications of these tests. Statistically significant strong correlation was established between these tests.

Isolation of mumps virus from the inner ear after sudden deafness.

A 26-year-old woman with bilateral otosclerosis underwent right stapedectomy with an excellent result. One year later, however, she developed symptoms of mumps and within two days was completely deaf in the right ear. Prompt surgical exploration excluded a complication of the otosclerosis and a perilymph fistula, but culture of a sample of perilymph grew mumps virus. The case provides direct evidence of a relation between mumps virus infection and inner-ear damage.

[Associated action of the measles and mumps viruses on the lymphatic apparatus of guinea pigs].

The immunomorphological and cytopathological properties of vaccine strains of measles and epidemic mumps viruses inoculated individually and together were studied in experiments in guinea pigs. The optimal doses of measles and mumps monovaccines were found to produce morphological changes of similar intensity in the lymphatic apparatus of guinea pigs. Measles virus stimulated increased alterative changes in lymphoid elements with increased inoculations; mumps virus produced maximum degeneration of the cells immediately after the first inoculation. The combined injection of both viruses enhanced proliferation of lymphoid cells, the extent of their alteration and the frequency of pathological mitoses more than each monovaccine individually. The increased frequency of pathological mitoses occurred mainly due to moderate non-lethal changes in mitosis in which there was a likelihood of the appearance of viable cells with an altered karyotype.

Identification of paramyxovirus-specific haemolysis-inhibiting antibodies separate from haemagglutinating-inhibiting and neuraminidase-inhibiting antibodies. 2. NDV and mumps virus haemolysis-inhibiting antibodies.

Egg-grown Newcastle disease (NDV) and mumps virus were used for preparation of rabbit hyperimmune sera against purified whole virus and projectionless virus particles. These sera and convalescent sera after natural NDV and mumps infections in chickens and human subjects, respectively, were studied in haemolysis-inhibition (HLI), haemagglutination-inhibition (HI) and neuraminidase-inhibition (NI) tests both before and after absorption with Tween 80-ether (TE) treated virus preparations. In addition, neutralization tests using the different sera were carried out. HI and NI antibodies and the major population of neutralizing antibodies in convalescent sera were removed by absorption with TE treated virus material without changing the titre of non-HI HLI antibodies. Rabbit hyperimmune sera directed against projectionless virus particles exhibited HLI antibody titres in marked excess of HI and NI antibody titres, whereas this was not found in sera against whole virus. Absorption with TE treated virus material resulted in removal of all demonstrable antibody activities in sera against whole virus. The corresponding absorption of sera against projectionless particles eliminated HI antibodies without changing the titre of non-Hi HLI antibodies. In rabbit hyperimmune sera, HI antibodies were of primary importance in neutralization tests. After addition of anti-gamma globulin to the test, an efficient neutralization was observed if mumps non-HI HLI antibodies were used whereas this was not found if NDV non-HI HLI antibodies were used.

Hemolysis-in-gel and neutralization tests for determination of antibodies to mumps virus.

A hemolysis-in-gel test for the demonstration of antibodies to mumps virus is described. The results were compared with those of neutralization tests using a modified microtechnique. In the neutralization test viral replication was demonstrated by the hemadsorption of guinea pig erythrocytes, the visibility of which could be further enhanced by the use of o-tolidine. Good correlation was found between the results of the two techniques. The hemolysis-in-gel test was simple to perform, rapid, sensitive, and shown to be a useful test for the demonstration of mumps antibodies.

[Biological properties of the mumps virus. Behavior using the T50 marker].

The authors studied the behaviour of 11 mumps virus strains or variants including the thermolabile standard Jeryl Lynn strain under thermal charge (50 degrees C/30 min). Varants were obtained from the Soviet vaccinal strains Leningrad-3 by cultivation under various conditions. Incubation temperature and cellular substrate played an important role therein. Variants with various behaviour in the marker T50 resulted. It was found that passages at 32 degrees C at limited dilutions as well as those on chick embryos or in cultures of chicken fibroblasts increased their thermolability. Possible correlations between their behaviour in the marker T50 and the degree of di attenuation are discussed. (Ta)

New tests for characterization of mumps virus antibodies: hemolysis inhibition, single radial immunodiffusion with immobilized virions, and mixed hemadsorption.

Hemolysis inhibition (HLI), single radial immunodiffusion (SRID) with immobilized virions, and mixed hemadsorption tests were used for measuring antibodies against mumps virus. Rabbit hyperimmune sera against mumps and early and late human convalescent sera were analyzed. All three tests identified antibodies against both hemagglutinin and the second major envelope component, hemolysin (fusion factor). The sensitivity of the HLI test corresponded to that of the hemagglutination inhibition (HI) test, but in some sera HLI antibodies occurred in greater quantity than HI antibodies. The SRID test readily identified rises in antibody titers in connection with acute infection. Due to its simplicity and lack of sensitivity to nonspecific inhibitors, it is recommended for use in this context. The mixed hemadsorption test showed a high sensitivity for specific identification of mumps antibodies. It therefore may be suitable for use in screening for immunity to mumps.

Mumps virus and ovarian cancer.

Thirty-four patients with carcinoma of the ovary were compared with controls matched for age, sex and racial origin. Previous mumps infection was determined by taking a history from the patient, by complement fixation test and by estimating neutralizing antibody titre. No significant differences between the two groups were found for any of the three methods used to estimate previous exposure to mumps virus. Therefore this study did not confirm previous hypotheses that mumps infection confers a significant degree of protection against the development of ovarian cancer. A relatively small proportion of cases could possibly be due to lack of such protection, but in this study not more than 30% at the 5% fiducial limit.

Selective inactivation of hemagglutinin and neuraminidase on mumps virus.

The thermal stability and the effect of guanidine on the hemagglutinin and neuraminidase of three strains of mumps virus were compared. The heat inactivation of hemagglutinin resulted in the concomitant loss of neuraminidase. The effect of guanidine at various molarities showed that the neuraminidase was more sensitive than the hemagglutinin and a selective inactivation was obtained after exposure to 1.5 M guanidine. However differences in sensitivity of both activities (hemagglutinin and neuraminidase) to heat and guanidine inactivations were observed among strains and correlated with differential susceptibility to non-specific inhibitors of the strains.

Nervous system affections caused by the mumps virus.

Hippocrates probably first described mumps parotitis, but not until 1758 was affection of the central nervous system reported in this disease. Mumps meningitis, encephalitis, myelitis, polyradiculitis and cranial neuritis are now well known, and may occur without clinical parotitis. Meningitis occurs most commonly, encephalitis, cranial neuritis and polyradiculitis less often, and myelitis rarely. They may present individually or in combination. A patient is described who first developed acute mumps meningoencephalitis, without clinical parotitis. Transverse myelitis occurred two weeks later, and finally optic neuritis ten days following the myelitis. Slow but complete recovery followed. Attention is directed to the various ways mumps can affect the nervous system. This virus should always be considered among possible etiologic agents causing such neurologic syndromes.

Ultrastructure of mumps virus replication in organotypic cultures of hamster choroid plexus.

Organotypic cultures of newborn hamster choroid plexus were inoculated with equal titre doses of newly isolated or hamster adapted strains of mumps virus. The ultrastructure of virus replication in choroid epithelial cells of the cultures was compared. No qualitative differences were observed; however, the adapted strain produced significantly greater numbers of virions and earlier destruction of the cultures. These findings are consistent with previous in vivo observations of the ultrastructure of the replication of these strains in the newborn hamster central nervous system. This in vitro study leads further support to the hypothesis that differences in the in vivo biological effects of the virus strains are primarily the result of virus-cell rather than virus-host interactions.

Possible role of mumps virus in the etiology of ovarian cancer.

Eighty-four ovarian cancer (OCa) patients and 84 controls with nonmalignant conditions matched by age and ethnic origin were interviewed with regard to clinical mumps history and their sera were tested for complement fixation (CF) mumps antibodies. OCa patients differed from the controls in the response to past mumps infection in two respects: 1) They appeared to be more likely to have developed subclinical mumps as evidenced by a lower rate of clinical mumps history in the presence of serological evidence of similar infection rates among those with positive and those with negative clinical mumps history. 2) They tended to present lower persistent mumps CF antibody titers. These results may be interpreted to indicate that an immunological incompetence enables the development of OCa possibly through a direct etiologic role of mumps virus.
