    Description / Table of Contents: Zusammenfassung Bei 27 splenektomierten Patienten, die aus traumatologischer (n=13) bzw. hämatologischer Indikation (n=14) splenektomiert worden waren und 31 immunologisch gesunden Kontrollpersonen gleicher Alters- und Geschlechtsverteilung wurden die Serumimmunglobuline M, A, G, D und E, die Komplementfaktoren C3, C4 und die Gesamtkomplementaktivität gemessen. Zusätzlich wurden eine Zählung der peripheren Gesamtlymphozyten, der B- und T-Lymphozyten sowie die Transformationsteste mit Hilfe unspezifischer Mitogene, wie Phytohämagglutinin, Concanavalin A und Pokeweed-Mitogen und die Phagozytosekapazität der polymorphkernigen neutrophilen Granulozyten mit Hilfe des Nitroblautetrazoliumtestes durchgeführt. Signifikant höhere Werte (p〈0,01) ergaben sich beim Vergleich aller splenektomierten Patienten und den Kontrollpersonen für die absoluten peripheren Gesamtlymphozyten, B- und T-Lymphozyten. Bei den Stimulationsversuchen zeigten sich für das Mitogen Phytohämagglutinin signifikant niedrigere (P〈0,01)3H-Thymidineinbauraten für die splenektomierten Patienten gegenüber den Kontrollpersonen. Die milzexstirpierten Patienten wiesen eine signifikant niedrigere (p〈0,01) IgM-Serumkonzentration auf als die verglichenen Kontrollpersonen. Keine signifikanten Differenzen zeigten sich beim Vergleich der postoperativen Zeitabstände von 7 Monaten bis zu 5 Jahren und von 6 bis zu 14 Jahren nach Splenektomie. Die Gegenüberstellung der aus traumatologischen und hämatologischen Indikationen splenektomierten Patienten ließen statistisch keine signifikanten Ergebnisse erkennen. Die Bedeutung der Milz für die primäre Immunantwort des menschlichen Organismus wird diskutiert.
    Notes: Summary In twenty-seven splenectomized patients, who had undergone splenectomy for trauma (n=13) or haematologic disorders (n=14) and thirty-one immunologically healthy persons, matched for age and sex, the following immunological parameters were examined: Serumimmunglobulins M, A, G, D and E, complementfactors C3, C4 and the serum haemolytic complement activity (Ch 50), as well as the ratio and in vitro reagibility of B- and T-lymphocytes measured by transformation responses to the non-specific mitogens Phytohämagglutinin, Concanavalin A and Pokeweed-Mitogen. The phagocytic capacity of polymorphological neutrophils was tested by the Nitrobluetetrazoliumtest. Total peripheral lymphocytes, B- und T-lymphocytes from splenectomized patients were significantly higher than in healthy controls (p〈0.01). The PHA response in splenectomized patients was significantly depressed (p〈0.01) as compared to nonsplenectomized controls. Also IgM serum concentration was found to be significantly lower in these patients (p〈0.01). No differences were observed between patients, who had been splenectomized 7 months to 5 years or 6 to 14 years ago. The comparison of persons splenectomized for traumatological or haematological disorders showed statistically no significant differences. The importance of the spleen for the primary immune response is discussed.

    Notes: Abstract Multiple sclerosis patients-111 of them-were typed for theHLA-D allelesw1, w2, andw3 and a new determinant, EI. Statistically significant increase was obtained for thew2 andw3 frequencies as compared to healthy controls. The distribution of HLA-D phenotypes among MS patients revealed a good fit according to the Hardy-Weinberg law. By calculating linkage disequilibrium parameters, theHLA-B7,Dw2 allele combination was found to be more closely associated than in normal controls, whereas forHLA-Bw35, Dw1, no linkage disequilibrium could be detected in the patients' group. From these data we conclude that in multiple sclerosis, the disturbance affects the frequency ofDw3 and the gametic association between alleles of theHLA-B andD loci, as well as the already known increase ofHLA-B7 andDw2.

    Description / Table of Contents: Zusammenfassung Bei 160 Patienten mit Multipler Sklerose aus dem epidemiologischen Areal Südniedersachsens wurden die HLA-Muster bestimmt und die Beziehung zur Prognose untersucht. Als einziger Unterschied zwischen MS-Patienten und normalen Kontrollen ergab sich ein häufigeres Vorkommen von HLA-DW2 in der MS-Gruppe (44% im Vergleich zu 21%). Der Progressions-index (Behinderungsgrad dividiert durch Erkrankungsdauer) war vergleichbar für DW2-positive und DW2-negative Patienten. Wir konnten somit die ungünstigere Prognose, die DW2-positive Patienten nach der Literatur haben sollen (Jersild et al. 1973; Raun et al. 1980), nicht bestätigen, obwohl wir methodisch ebenso vorgegangen sind wie die letztgenannten Autoren.
    Notes: Summary The histocompatibility pattern of 160 patients with multiple sclerosis (MS) living in the epidemiological area of Southern Lower Saxony was determined and compared to a control population. The only significant difference was the more frequent occurrence of DW2 in the patient group (44% vs. 21%). Taking a progression index (grade of disability divided by the duration of the disease) as a measure for prognosis no difference could be found between the DW2 positive and the DW2 negative patients. The reason why we could not confirm the worse prognosis for DW2 positive patients found by Jersild et al. (1973) and Raun et al. (1980) remains to be investigated.

    Notes: Summary Circulating interferon was found in volunteers immunized with 3.0 ml and 1.0 ml doses of human diploid cell strain (HDCS) rabies vaccines. Peak interferon titres were observed 17–25 hours after primary vaccination and the response diminished upon revaccination. The response was dose-related and did not correlate with the antigenic value of the vaccines or with the titre of infectious virus in the vaccines before inactivation.

    Notes: Abstract Circulating levels of immunoglobulin E (IgE) have been determined by solid-phase radioimmunoassay in groups of patients with different clinical courses of multiple sclerosis (MS) and in healthy controls. The geometric mean of the serum IgE level in the MS patients was somewhat less than that in the control group (64 U/ml), but this decrease was not significant. Contrary to the findings of Campbell [1, 2, 3, 4], circulating IgE in the MS patients was not specifically adsorbed on bovine myelin basic protein (BMBP) immunoadsorbent and does not give a positive immunofluorescence using guinea pig brain sections.

    Notes: Abstract The prevalence of HBsAg and anti-HBs has been determined by solidphase radioimmunoassay in 1815 university hospital employees and compared with the results obtained by investigating 131 metal workers and 86 laboratory technicians. Hospital personnel and here especially dialysis staff members and laboratory workers is at higher risk to acquire a hepatitis B virus infection than population compartments without contact to patients or blood. Electronmicroscopic studies revealed that a considerable number of the blood samples of HBsAg-positive staff members contained Dane-particles. These employees have to be considered infectious and possibly present a hazard to the patients they take care of.

    Description / Table of Contents: Zusammenfassung Bei 47 Patienten (46 Kinder und l Erwachsener), die einseitig oder beidseitig an einem Retinoblastom erkrankt waren, wurde der Titer des carcinoembryonalen Antigens (CEA) bestimmt. Der CEA-Titer der Kinder mit aktiven Retinoblastomen betrug 1,44± 0,26 ng/ml (¯x ± SEM). Die Patienten, deren Retinoblastome unter der Therapie inaktiv geworden waren, wiesen keinen signifikant niedrigeren CEA-Titer auf. Dagegen lag der CEA-Titer einer Gruppe von Kindern, bei denen ein Auge wegen eines einseitigen Retinoblastoms entfernt worden war, signifikant (P〈0,1) niedriger. Die enukleierten Augen von 25 Kindern wurden histologisch untersucht. Die Kinder, deren Retinoblastome histologisch einen Einbruch in den Opticus oder in die Aderhaut zeigten, hatten gegenüber den Kindern, deren Retinoblastome auf die Netzhaut beschränkt waren, einen signifikant (P〈0,1) häheren CEA-Titer.
    Notes: Summary In 47 patients (46 children and 1 adult) with unilateral and bilateral retinoblastoma, the titer of the carcinoembryonic antigen (CEA) was determined. The CEA titer of children with active retinoblastomas was 1.44±0.26 ng/ml (¯x± SEM). Those patients whose retinoblastoma was inactivated by therapy did not show a significantly lower CEA titer. In the group of children with one eye removed because of a unilateral retinoblastoma, the CEA titer was significantly (P〈 0.1) lower. The globes of 2 5 children were examined histologically. In those cases with invasion of the optic nerve or choroid, the CEA titer was significantly higher (P〈 0.1) as compared with those where the tumor was limited to the retina alone.
