    Notes: The C3H UV-induced fibrosarcoma, 1591, is highly immunogenic and, therefore, is readily rejected when transplanted into immunocompetent syngeneic recipients. Previous analysis of 1591 with tumour-specific or H-2-reactive monoclonal antibodies revealed that this antigenicity might be due to the expression of two novel class I major histocompatibility complex (MHC) antigens. In this report we describe the molecular cloning and initial characterization of three genes which account for all of the unique serological class I reactivities observed on this tumour. These include two distinct, but highly conserved, H-2L-like genes, and a third gene the product of which bears determinants which are characteristic of both the tumour and of class I products of the H-2k haplotype. Moreover, each of these genes contains a polymorphic restriction enzyme fragment which is detected in the class I sequences of 1591 relative to normal C3H tissue. Since the expression of these polymorphic class I sequences is relevant to the immunogenicity of 1591, the mutational events by which these genes were generated may be significant to the immunobiology of this tumour.

    Notes: Ultraviolet tight (UV)-induced tumours in mice are often highly immunogenic and have unique (individually specific) antigens which cause tumour rejection in normal mice. The molecular nature of these unique ‘rejection’ or ‘transplantation’ antigens is not known. We have recently isolated a syngeneic monoclonal antibody (mAb), CP28, that recognizes a unique tumour-specific antigen on the UV-induced regressor tumour 1591-RE. Further analysis revealed that the antibody-recognized antigen represents a novel major histocompatibility complex (MHC) class I molecule. However, the relationship of this molecule to the unique T cell-recognized antigen that causes tumour rejection remained unresolved. In this study we have explored the relationship of the antibody-defined tumour-specific novel class I molecule to the rejection antigen, that we have previously defined with a cytolytic T cell (CTL) clone (‘anti-A’). Two different lines of evidence suggested a close relationship. First, it was found that random subclones of the 1591-RE tumour expressed different levels of the CP28-defined antigen which correlated with the level of lysis by the anti-A CTL clone. Second, the selection of antigen-loss variants using either the anti-A CTL clone or the mAb CP28 resulted in the simultaneous loss of both the CP28 as well as the ‘A’ antigen. This tight correlation strongly suggests a relationship between the antibody-defined and the T cell-defined antigen. However, the role of the antibody-recognized antigen in causing transplantation rejection still needs to be determined.

    Notes: Zusammenfassung Bei der Behandlung überlebender Muskelfasern aus dem Froschsartorius mit Neutralsalzlösungen treten charakteristische und differente Bilder der Querstreifung auf, die durch einen spontan eintretenden Kontraktionsprozeß bedingt und von der Art der angewandten Salze, sowie der Dauer ihrer Einwirkung abhängig sind. Beobachtungen, die bald nach Herstellung des Zupfpräparates angestellt wurden, zeigten besonders für hypotonische Konzentrationen, daß die Quanten der zu einem bestimmten Zeitpunkt vorhandenen typischen Querstreifungsformen in einem eindeutigen Zusammenhang mit der Stellung des betreffenden Salzes in den Kationen- und Anionenreihen stehen, wie sie für die Erhaltung der Muskelerregbarkeit gelten. Es liegt also hier eine weitgehende Parallele zwischen einer differenten Beeinflussung der Struktur und der Punktion der Muskelfasern (Ergebnisse der Erregbarkeitsversuche) vor, die als eine weitere Stütze der Höberschen Hypothese von der kolloidchemaischen Wirkung reiner Neutralsalzlösungen auf lebende und überlebende Organe und Organismen aufgefaßt werden darf.

    Notes: Zusammenfassung Bei der Röntgenemissionsanalyse mit Kathodenstrahlenanregnng, die hinsichtlich ihrer Fehlerquellen untersucht wird, werden chemische Umsetzungen auf der Antikathode festgestellt. Eine neue Analysenmethode wird ausgebildet und geprüft, bei welcher Temperatureffekte nicht möglich sind. Die neue „Fluoreszenzmethode“ gestattet also ohne weiteres, leichtflüchtige Stoffe und auch Losungen zu untersuchen.

    Description / Table of Contents: Zusammenfassung Unter einem neuartigen Konzept konnte im Krankengut der Hamburger Universitätsklinik in den Jahren 1967–1984 (n = 285) in der Behandlung intestinaler Strahlenfolgen eine Letalität von 4,4% erzielt werden. Die Diagnostik der Notfallsituation muß sich auf das Erforderliche beschränken. Perforationen sind klinisch, Blutungen (n = 89) endoskopisch und Obstruktionen mit einer Sensitivität von 93% in der Gastrografinpassage zu belegen. Im Intervall muß die Diagnostik ausführlich sein um synchrone Strahlenfolgen (12,5%), Carcinomrezidive (9,5%) und Zweittumoren im Bestrahlungsbereich (5%) erkennen zu können. Therapeutisch geht es um die Vermeidung der Notfalloperation (Letalität bis 50%) und die konsequente Elektivintervention. Verfahren der Wahl ist die Resektion. Im Rezidiv und im Notfall müssen alternative Verfahren angewandt werden.
    Notes: Summary The diagnostic procedures involved in radiation injury to the intestinal tract must be differentiated. In emergency cases, only urgent necessary steps are allowed. Before elective surgery the diagnostic regimen must be able to detect synchronous radiation sequelae (12.5%), cancer recurrence (9.5%) and post-radiation tumours (5%). Surgical therapy has to avoid emergency intervention, so elective operation must be performed. The procedure of choice is resection with end-to-end-anastomosis. In case of tumour recurrence, perforation or intestinal obstruction, alternative procedures like intestinal bypass should be performed. Such an approach keeps the mortality low (4.4%). These topics are discussed with reference to 285 of our own cases within the period from 1967 to 1984 at the Surgical Department of the University of Hamburg.

    Description / Table of Contents: Zusammenfassung In einer retrospektiven Studie an 95 folliculären Schilddrüsencarcinomen wurden verschiedene morphologische und klinisch-biologische Parameter auf ihre prognostische Bedeutung geprüft. Das klinische Verhalten der Tumoren wurde vorrangig durch Vorhandensein oder Fehlen einer Kapselbegrenzung bestimmt: Grob invasive Carcinome zeigten sechsfach häufiger einen letalen Verlauf als gekapselte Neoplasien. Ein ungünstigeres Verhalten ergab sich ferner bei Manifestation des Tumors im höheren Lebensalter (Schwellenalter: 52 Jahre) und bei Nachweis einer oxyphilen Differenzierung, weiterhin bei Vorliegen von Lymphknotenmetastasen, einer Halsweichteilinfiltration und - im Fall gekapselter Carcinome - von Fernmetastasen. Dagegen hatten die Faktoren Differenzierungsgrad und Geschlecht keinen signifikanten Einfluß auf die Prognose. Bei 22 Tumoren erfolgten cytophotometrische und flußcytometrische DNS-Bestimmungen. Der diagnostische Nutzen dieser Verfahren war dadurch limitiert, daß an Hand der DNSHistogramme in der Mehrzahl der Carcinome keine eindeutige Dignitätsbeurteilung getroffen werden konnte. Dagegen erwiesen sie sich als brauchbares Instrument für die Prognosebeurteilung individueller grob invasiver Tumoren. Die diagnostische, differentialtherapeutische und prognostische Bedeutung der Befunde sowie deren Relevanz für die Subklassifikation folliculärer Schilddrüsencarcinome wird diskutiert.
    Notes: Summary A retrospective study of 95 follicular thyroid carcinomas was conducted to evaluate the prognostic value of different morphological and clinical features. The biological behaviour of these tumours was primarily influenced by presence or absence of a capsule type of confinement: the frequency of lethal outcome among widely invasive carcinomas was six times higher than among encapsulated neoplasms. Furthermore, dismal prognosis could be demonstrated for tumours occurring in older patients (with a sharp break in the prognosis at the age of 52 years) and for those lesions which displayed oxyphilic metaplasia. The same effect was shown for presence of lymph node metastasis, tumour invasion of the cervical soft tissue and, for the case of encapsulated carcinomas, distant haematogenous spread. Conversely, the degree of differentiation and the patients' sex proved to have no significant influence on prognosis. In 22 carcinomas, cytophotometric and flow-cytometric determinations of DNA values were performed. These procedures revealed to have only limited diagnostic value, since for the majority of the tumours, benignancy or malignancy could not be judged from the DNA histograms. However, DNA measurements proved to contribute valuable information for the prognosis in individual cases of widely invasive follicular carcinomas. The discussion focuses on the diagnostic, therapeutic and prognostic relevance of these findings and on their impact on subclassification of follicular thyroid carcinomas.

    Description / Table of Contents: Schlüsselwörter Das Magencarcinom ist durch das duale TNM- und das R-(Residualtumor)-System vergleichbar geworden. Davon hat auch die chirurgische Methodenwahl profitiert. Durch systematische Ausdehnung der Operation versucht man, auch beim ausgedehnteren Tumor (T2, N2, M0) die örtliche Umschriebenheit operativ zu kompensieren. Besonderes Augenmerk gilt der radikalen Lymphadenektomie der Kompartimente 1 und 2. Durch bessere Techniken und geminderte Risiken nimmt der Trend zur kurativen Gastrektomie deutlich zu. Adjuvante Massnahmen und Forschung der Tumorzellbiologie machen aktuelles klinisches Interesse notwendig. Die „angeblich festgefahrene Chirurgie des Magencarcinoms” hat eine vielfältige erfreuliche Belebung erfahren.
    Notes: Summary The simultaneous use of TNM and R- (Residual tumor) classification has made gastric carcinoma comparable. The choice of surgical procedure has also profited from it. Through systematic radicality (also by extensive tumor T2, N2, M0) surgical attempts are made to compensate for the local limitations. The radical lymphadenectomy of compartment I and 2 should be regarded with special consideration. With better techniques and reduced risks the tendency to perform curative gastrectomy is increasing. Adjuvant measures and research in tumor biology are making current clinical interest necessary. The so-called standstill of gastric carcinoma surgery has gained tremendous activity.
