    Description / Table of Contents: Zusammenfassung Disseminicrte intravasculäre Gerinnsel bei perinatal verstorbenen Kindern werden häufig beobachtet. Schock, Hypoxie und Acidose scheinen von pathogenetischer Bedeutung zu sein. Eine Beziehung zur mütterlichen Erkrankung bzw. zur geburtshilflichen Komplikation besteht nur in seltenen Fällen. 1. Es erschien interessant, zu prüfen, ob Frühstadien der disseminierten intravasculären Cerinnung beim Neugeborenen zu erfassen sind. Der Fibrinomonomernachweis im Nabelvenenblut erfolgte mit dem Alkoholtest nach Godal und Abildgaard. 2. 32 gesunde Neugeborene und 18 mit Zeichen der Asphyxie wurden untersucht. In der Gruppe der asphyktischen Kinder wurden statistisch signifikant gehäuft Fibrinmonomere im Nabelvenenplasma beobachtet. Eine Beziehung zur Dauer von Schock, Hypoxie und Acidose scheint zu bestehen.
    Notes: Summary Disseminated intravascular fibrin depositions (DIC) are frequently seen in infants dying in the perinatal period. Shock, hypoxia and acidosis seem to be of pathological significance. A relation between the occurrence of DIC in the newborn and maternal disease and/or obstetrical complication is only rarely observed. 1. It was studied whether an early state of DIC in the newborn could be detected. The presence of fibrin monomeres was evaluated in cord blood by the ethanol test (Godal and Abildgaard). 2. 32 apparently healthy newborns and 18 newborns showing signs of asphyxia were examined. In the group of asphyctic infants, fibrin monomeres were move frequently observed in cord blood. The difference to healthy newborns was statistically significant. The occurrence of fibrin monomeres seemed to be related to the duration of shock, hypoxia and acidosis.

    Description / Table of Contents: Zusammenfassung Das Auftreten zweier Fibrinogenderivate mit höherem Molekulargewicht als dem des Fibrinogens im Nabelvenenplasma asphyktischer Neugeborener konnte in dieser Studie bestätigt werden. Nachdem aus Einzelproben ein Pool gebildet worden war, wurde dieser der Agarose-Gel-Filtration unterworfen, und anschließend wurden die eluierten Proben elektrophoretisch untersucht. Elektrophoresen in 5 Mol Harnstoff deuteten darauf hin, daß das 0,27 Derivat ein Komplex ist, der sich vorwiegend aus untereinander nicht kovalent gebundenen Komponenten zusammensetzt und der in 5 Mol Harnstoff dissoziiert. Möglicherweise entsteht dieser Komplex (Fibrinogen-Fibrinmonomer-Komplex) durch die Wirkung von Thrombin auf Fibrinogen. Das 0,17 Derivat setzt sich vorwiegend aus untereinander kovalent gebundenen Komponenten zusammen. Es könnte sich hierbei um ein Plasminderivat quervernetzten Fibrins (Defekt-Polymer) handeln.
    Notes: Summary The occurrence of two fibrinogen derivatives with a molecular weight higher than that of the parent molecule in cord vein blood of asphyctic newborns was confirmed in this study. Agarose gel filtration and electrophoresis of the eluted fractions were performed from pooled plasma. Electrophoretic studies in the presence of 5 M urea indicated that the 0.27 derivative is a complex formed of predominantly non covalently linked components, which dissociates in the presence of 5 M urea. It might be assumed that this derivative (fibrinogenfibrinmonomer complex) results from the action of thrombin on fibrinogen. The 0.17 derivative consists of predominantly covalently linked components. It might be originated from the action of plasmin on stabilized fibrin (defect polymer).

    Description / Table of Contents: Zusammenfassung Die Häufigkeit intravasculärer Mikrothromben bei perinatal verstorbenen Neugeborenen veranlaßte die folgende Untersuchung. In nativen Plasmaproben und nach Fällung des Plasmas mit 2,5 molarem β-Alanin wurden hochmolekulare Fibrinogenderivate durch PAA-Gel-Elektrophorese und Intra-Gel-Immunpräzipitation identifiziert. Zwei Komponenten, die langsamer als Fibrinogen wanderten, wurden beobachtet. Ihre relativen elektrophoretischen Beweglichkeiten betrugen 0,17 und 0,27 (Fibrinogen: 0,43)×10−5 cm2/V×sec. Aufgrund des Laufverhaltens in der zweidimensionalen Gel-Elektrophorese in Gelen verschiedener Porengröße kann für beide Komponenten ein höheres Molekulargewicht, als das des Fibrinogens angenommen werden. Die beschriebenen Derivate wurden im Nabelvenenblut asphyktischer Neugeborener beobachtet. Ihr Auftreten war mit einem positiven Äthanoltest, einem statistisch signifikanten Abfall der Thrombozyten und des Fibrinogens und mit Zeichen fetaler Asphyxie korreliert.
    Notes: Summary The high incidence of intravascular fibrin deposits in stillbirths and newborns dying in the perinatal period prompted us to undertake the following study. High molecular weight derivatives of fibrinogen were identified in native plasma and in plasma after 2.5 M β-alanine precipitation by PAA gel electrophoresis and intra-gel immunoprecipitation. Two components were observed which migrated more slowly than fibrinogen. Their relative electrophoretic mobilities were: 0.17 and 0.27 (fibrinogen: 0.43)×10−5 cm2/V×sec. Two-dimensional gel electrophoresis in gels of different pore size indicated a higher molecular weight than that of fibrinogen for both components. The derivatives described were found in cord vein plasma samples of asphyctic newborns. Their occurrence was accompanied by a positive ethanol test, by a statistically significant decline of platelets and fibrinogen and by signs of fetal distress.

    Description / Table of Contents: Summary Soluble fibrin monomer complexes (SFMC) were determined in users of different oral contraceptives. Quantitative gel filtration of β-alanin precipitated plasma samples yielded the relative (per cent of total fibrinogen content) and absolute (mg per 100 ml plasma) amount of SFMC. Increased levels of SFMC were observed in users of oral contraceptives, when compared to age, parity and socioeconomic background matched control groups. This increase was more pronounced in users of Neogynon (0.05 mg ethinyl estradiol, 0.25 mg norgestrel) than in the ones using Microgynon (0.03 mg ethinyl estradiol, 0.15 mg norgestrel). Users of Ovulen (0.1 mg mestranol, 1 mg ethynodiol diacetate) in addition to the rise of SFMC levels exhibited elevated fibrinogen levels in plasma. The data presented indicate a limited state of hypercoagulability in users of oral contraceptives.
    Notes: Zusammenfassung Lösliche Fibrinmonomerkomplexe (LFMK) wurden bei Frauen bestimmt, die verschiedene Ovulationshemmer einnahmen. Plasmaproben wurden mit β-Alanin gefällt und durch Gelfiltration der relative Gehalt an LFMK (Prozent des Gesamtfibrinogens) und der absolute Gehalt (mg pro 100 ml Plasma) bestimmt. Es wurden Frauen, die Ovulationshemmer einnahmen, mit Kontrollgruppen verglichen, die hinsichtlich Alters, Zahl der Schwangerschaften und sozioökonomischen Milieus übereinstimmten. Es konnte ein signifikant erhöhter Spiegel von LFMK gegenüber den Kontrollgruppen festgestellt werden. Dieser Anstieg war bei der Gruppe, die Neogynon (0,05mg Äthinylöstradiol, 0,25 mg D-Norgestrel) einnahmen, größer als bei einer Gruppe die Microgynon (0,03 mg Äthinylöstradiol, 0,15 mg D-Norgestrel) einnahmen. Bei der Gruppe, die Ovulen (0,1 mg Mestranol, 1 mg Ethynodioldiacetat) nahmen, konnte zusätzlich zu dem Anstieg der LFMK ein erhöhter Fibrinogenspiegel nachgewiesen werden. Die Befunde zeigen, daß die Einnahme von Ovulationshemmern zu einer begrenzten Hyperkoagulabilität führt.

    Notes: Carcinogenesis in the human colon is associated with a marked increase in the tissue content of the urokinase-type plasmmogen activator (u-PA). This study was performed to determine the type of cells responsible for the u-PA increase in carcinomas of the colon and in their precursor lesions, the adenomas, by immunohistological evaluation applying monoclonal antibody 3689 directed to the β-chain of u-PA.Normal intestinal mucosa (n= 17) showed hardly any staining of u-PA, but some lamina propria cells were faintly positive. Carcinomas (n= 17) and adenomas (n= 16) showed a considerable and comparable staining intensity of u-PA in neoplastic columnar epithelial cells, and this staining was found to be diffuse and cytoplasmic. In a majority of the neoplastic tissues the u-PA staining was found to be patchy and not related to known risk markers of malignancy such as dysplasia in the adenomas, or to prognostic determinants such as Dukes' classification or differentiation in the carcinomas. The observation of strong u-PA positive lamina propria cells in adenomas but infrequently observed in normal mucosa and carcinomas was noteworthy. u-PA staining intensity of the tissue sections was found to correlate well with the u-PA antigen level in the tissue extracts determined by ELISA (r= 0.52, P= 0.0001) but poorly with the u-PA activity determined enzymatically (r= 0.28, P= 0.05).In conclusion, the u-PA increase in neoplasia of the human colon can be attributed to an increased diffuse cytoplasmic content of u-PA in neoplastic columnar epithelial cells.

    Notes: Aims: Ductal carcinoma in situ (DCIS) is a pre-invasive form of mammary carcinoma with no microscopic evidence of cancer cell invasion through the basement membrane. However, for initiation of invasion, tumour cells have to acquire and focus proteolytic activity on to the cell surface in order to infiltrate the surrounding extracellular matrix. The receptor (uPA-R or CD87) for the serine protease urokinase-type plasminogen activator (uPA) plays a central role in invasion and metastasis. This study was performed to determine and localize m-RNA and protein of uPA-R in ductal carcinoma in situ of the breast.〈section xml:id="abs1-1"〉〈title type="main"〉Methods and resultsWe analysed uPA-R mRNA and protein expression by in-situ hybridization and immunohistochemistry, respectively, in 50 formalin-fixed, paraffin-embedded specimens of DCIS. Three different antibodies were used to stain cell-associated uPA-R; chicken polyclonal antibody (pAb) HU277 and monoclonal antibodies (mAb) IID7 and 3936. In all cases, myoepithelial and stromal cells reacted with either antibody. Especially, reaction of macrophage-like cells with mAb 3936 resulted in a well-marked and bright staining. Applying mAb IID7, in 46 of the 50 breast specimens tumour cells showed a positive immunoreaction. Likewise pAb HU277 stained tumour cells in 40 of the 50 cases, whereas mAb 3936 reacted with only 24 of the 50 tissue sections. Endothelial cells were marked by both mAb IID7 and pAb HU277 (46/50 and 35/50, respectively); mAb 3936 did not label at all. All of the cell types stained by mAb IID7 and pAb HU277 also displayed reactivity with uPA-R mRNA-specific antisense oligonucleotides in in-situ hybridization.〈section xml:id="abs1-2"〉〈title type="main"〉ConclusionsOur results reveal the presence of the tumour invasion-related receptor for the protease uPA not only in invasive ductal breast carcinoma but also in different types of DCIS.
