    Description / Table of Contents: Zusammenfassung Es werden Serumproteine beschrieben, deren Bedeutung sowohl für die Schwangerschaft, als auch für das maligne Wachstum, bedingt durch die drastische Zunahme oder das erstmalige Auftreten, naheliegen. Da beiden Vorgängen immunologische Nichtreaktionen (Toleranz) gegen Fremdantigene eigen ist und in vitro Befunde für immunsuppressive Eigenschaften der beschriebenen Serumproteine vorliegen, kann an eine Funktion dieser Proteine im Rahmen der veränderten Immunität gedacht werden. Es wäre eine Rollenverteilung der sog. schwangerschaftsspezifischen Proteine, und der Proteine deren Produktion normalerweise nur in geringem Umfang im Organismus stattfindet, aber durch die Auswirkungen der Gravidität oder eines malignen Wachstums stimuliert wird, denkbar. Aufgabe der vom Neoplasma gebildeten Serumproteine könnte es sein, den efferenten Schenkel des Immunapparates zu blockieren. Sie würden antigene Determinanten der Tumorzelle besetzen und damit die spezifischen Reaktionsmechanismen der Effektor Zellen verhindern als auch den Tumor nicht angreifbar machen. Letzteres käme früheren Vorstellungen vom Glykoproteinmantel der Tumorzelle sehr nahe. Das humane Choriongonadotropin scheint in diesem Zusammenhang am besten untersucht zu sein und dieses Modell zu bestätigen. Den Serumproteinen die normalerweise in kaum nachweisbaren Mengen beim Gesunden vorkommen, käme dagegen die Funktion der Blockierung des afferenten Schenkels des Immunsystems zu, d.h. diese Proteine wären in der Lage den Erkennungsmechanismus immunkompetenter Lymphozyten außer Kraft zu setzen und die Sensibilisierung zu verhindern. Hierfür liefern sowohl das schwangerschaftsassoziierte α2 Glykoprotein im Electrophoretic Mobility Test als auch der Nachweis von α1-Fetoprotein Rezeptoren auf T-Lymphozyten, Hinweise.
    Notes: Summary Serum proteins are described the significance of which for pregnancy or for malignant growth is associated with their drastic increase or initial occurrence. In that immunological non-reaction (tolerance) against foreign antigen is inherent in both of the proceeding, and in that in vitro findings display immunosuppressive properties for the described serum proteins, a function within the scope of altered immunity can be conceived for these proteins. A dual role of the so called pregnancy-specific proteins and the pregnancy-associated proteins would be possible. The purpose of the neoplasma-derived serum proteins could be to block the efferent branch of the immune apparatus. They would occupy antigen determinants of the tumor cells and thereby inhibit the specific reaction mechanism of the effector cells as well as render the tumor invulnerable. The latter would closely resemble the earlier concept of a glycoprotein coat of the tumor cell. In this connection, the human Choriongonadotropin appears to be the best investigated and seems to confirm this model. The serum proteins, present in healthy individuals normally in almost indetectable amounts could, by contrast, acquire the function of blocking the afferent branch of the immune system. That is to say these proteins would be able to annul the recognition mechanism of immunologically competent lymphocytes, and to inhibit sensibilization. The electrophoretic mobility test of the pregnancy-associated α2-glycoprotein as well as the determination of α1-fetoprotein receptors on T-lymphocytes are evidence for this concept.

    Description / Table of Contents: Zusammenfassung Im Rahmen von Longitudinalstudien haben sich α2-PAG-Bestimmungen im Serum von Patienten mit Mammakarzinom, Bronchialkarzinom, gynäkologischem Karzinom, Kehlkopfkarzinom oder Melanom als ein möglicher laborchemischer Parameter erwiesen, um Aussagen über die eingeschlagene Therapie, Tumorrezidive und Metastasen zu machen. Bei trophoblastischen Tumoren und Gastrointestinalkarzinomen sind die bisher publizierten Ergebnisse noch divergierend. Wegen der großen individuellen Strubreite der α2-PAG-Konzentrationen und wegen der stark unterschiedlichen α2-PAG-Spiegel bei Männern und Frauen sind Einzelbestimmungen dieses Proteins ohne Wert. Es fehlt noch eine detaillierte Abklärung über die Pathomechanismen, denen dieses Protein unterliegt, und damit die grundlegende Kenntnis über die Veränderungen, bei denen es neben Schwangerschaft und Neoplasien zu Änderungen des physiologischen α2-PAG-Serummusters kommt.
    Notes: Summary Long-term studies of α2-PAG in sera of patients with breast cancer, bronchial carcinoma, gynaecological carcinoma, melanoma and laryngeal carcinoma have proved that α2-PAG is a possible laboratory parameter for the assessment of recurrence of tumour and metastasis. The results published for trophoblastic tumour and gastrointestinal carcinoma are still divergent. Because of the large individual range of α2-PAG concentrations and the widely differing α2-PAG levels in men and women single determinations of this protein are without value. A detailed classification of the pathological mechanisms to which these proteins are submitted is still missing and consequently we have no fundamental knowledge of diseases that apart from pregnancy and neoplasia lead to changes in the physiological α2-PAG serum concentration.

    Notes: Summary Peripheral blood lymphocytes from a total of 300 subjects including normal controls and patients with malignant and non-malignant disorders were investigated to determine their ability to agglutinate with Poly-l-lysine 3400 (PAL-test). A high level of association between clinically evident cancer and a positive reaction was confirmed. Lymphocytes from 72 of 90 patients with malignant diseases as well as 33 of 140 patients with non-malignant processes showed positive reactions. All healthy controls were negative. The positive evidence of the PAL-test amounted to over 80%. The results and possible mechanisms of the PAL-test are discussed.

    Notes: Summary The clinical application of enzyme immunoassay for the determination of the prostate-specific acid phosphatase is reported. 277 sera were investigated in the diagnosis as well as in tumour monitoring and a good correlation with the clinical stage was found. In prostatic carcinomas 5 of 13 with stage T1, 11 of 12 patients with stage T2, 16 of 16 patients with T3 and 19 of 19 patients with stage T4 disease had values above 1 ng/ml. In prostatic adenomas (n=69) in prostatitis (n=40) and in other carcinomas of the urogenital tract (n=28), (renal carcinomas, carcinomas of the bladder and the penis) the values of the prostate-specific acid phosphatase measured by the enzyme immunoassay 131 of 137 were under 1 ng/ml. A comparison of random samples with the radioimmunoassay for this enzyme showed good correlation.

    Notes: Abstract: In this multicentre (five centres in Germany), randomised, double-blind, comparative study, 150 patients with painful degenerative joint disease according to EULAR criteria received either oxaceprol (200 mg three times daily) or diclofenac (25 mg three times daily) for 20 days. Joint function, the primary variable, assessed according to Lequesne’s indices, improved equally in both treatment groups to a clinically relevant degree. Joint mobility improved by approximately 60% in both groups. By the end of therapy in both groups, the period of pain-free walking time had more than doubled and subjectively evaluated pain perception (VAS) was reduced by almost 50% without any significant differences between the treatments. The incidence of adverse drug reactions was similar in both groups but oxaceprol induced milder symptoms. Oxaceprol is as effective and better tolerated than diclofenac in the treatment of osteoarthritis.
