    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Es werden zeit- und kostensparende Methoden für die Vaterschaftsbegutachtung beschrieben. Siebzehn genetische Systeme werden in sechs Gruppen unterteilt. 1. Gruppe: Transferrin (Tf), Faktor B (BF) und Phosphoglucomutase 1 (PGM1); 2. Gruppe: Gc-System (Gc) oder α1-Antitrypsin (PI) und α-2HS-Glycoprotein (HSGA); 3. Gruppe: Komplement-Komponente C6 und C7, Faktor 13B (F13B) und Plasminogen (PLG); 4. Gruppe: Haptoglobin (Hp), C8 α-γ Kette (C81) und Faktor I (IF); 5. Gruppe: saure Erythrozyten-Phosphatase (ACP), Esterase D (ESD), Glutamat-Pyruvat-Transaminase (GPT); 6. Gruppe: 6-Phosphogluconat Dehydrogenase (PGD) und Glyoxalase I (GLO). Jede Gruppe wurde gleichzeitig mittels Elektrophorese oder isoelektrische Fokussierung (IEF) mit Färbung oder Immunoblotting untersucht. Diese Methoden erwiesen sich in der Praxis als zeit- und kostensparend und erleichtern die vorübergehende Aufbewahrung und Dokumentation der Elektrophorese-Bilder.
    Notizen: Summary Time- and cost-saving methods for paternity testing are described. Seventeen genetic systems were divided into six groups: (1) transferrin (Tf), factor B (Bf), and phosphoglucomutase 1 (PGM1); (2) group-specific component (Gc) or α1-antitrypsin (PI) and α2HS-glycoprotein (HSGA); (3) complement components C6 and C7, factor 13B (F13B), and plasminogen (PLG); (4) haptoglobin (Hp), C8 α-γ chain (C81), and factor I (IF); (5) red cell acid phosphatase (ACP), esterase D (ESD), and glutamic-pyruvic transaminase (GPT); and (6) 6-phosphogluconate dehydrogenase (PGD) and glyoxalase I (GLO). Each group of systems was typed simultaneously by electrophoresis or isoelectric focusing (IEF) followed by staining or immunoblotting. These methods are very practical because they afford a considerable saving of time, work and expense, and facilitate semipermanent preservation of electrophoretic patterns.

    Notizen: Summary Signet ring cell carcinoma was induced in canine stomachs by N-ethyl-N′-nitro-N-nitrosoguanidine, and modes of cell proliferation and turnover in the carcinoma were studied by 3H-thymidine autoradiography in conjunction with morphometric analysis. From 2 to 15 months after the cessation of 8 months carcinogen treatment, carcinomas in an early stage were obtained. Most of the cancer tissues confined to the lamina propria showed a layered structure. This comprised three layers; the superficial and the deep layer were composed of signet ring cells, and the middle layer was composed of small round cells. The dogs were labeled with 3H-thymidine by s.c. injection and by local infusion of the celiac artery. Flash-labeled autoradiographs revealed that most 3H-thymidine incorporating cancer cells were located around the middle layer, with a small amount of mucin. Using a pulse labeling experiment, those labeled carcinoma cells were shown to migrate from the middle layer towards the surface. Morphometric analysis of the autoradiographs showed that the small cells in the middle layer migrated upwards and produced mucin to become full-blown signet ring cells by 5.5 days. In 15 days, most labeled cancer cells in the superficial layer had disappeared. This mode of cellular turnover appeared to mimic a cell renewal system of the normal gastric mucosa. If the cancer cells turn over in this way, the tumor must grow slowly, remaining as an intramucosal cancer for a relatively long period.
