    Notes: Summary Anaesthesia of swine (Sus scrofa domestica) and its breeding varieties (miniature pig) is of increasing importance for research. Endotracheal intubation is particularly difficult because of unusual proportions of the whole skull, above all, of the pharynx. On account of the deviant, stumpy shape of its skull, only the Vietnamese swine (Sus scrofa “familiaris”) can be intubated by means of an instrumentarium as used in man. A special set of intubation instruments facilitates the endotracheal intubation of the common pig (Sus scrofa domestica). The method of intubation, performance of anaesthesia and possible complications are described.

    Description / Table of Contents: Zusammenfassung Berichtet wird über den ungewöhnlichen Verlauf eines Morbus Whipple. Unter antibiotischer Therapie tritt klinisch eine völlige Beschwerdefreiheit ein. Mehrfache Kontrollbiopsien zeigen eine hochgradige und progrediente Kollagenisierung des Stratum proprium mucosae, die besonders auch pericellulär und im Bereich der epithelialen Basalmembran entwickelt ist. Lymphocyten, Plasmazellen und interepitheliale lymphoide Rundzellen sind stark vermehrt. Immunologisch ist Serum-Komplement (C3-Fraktion) erniedrigt. Immunhistologisch findet sich nach Inkubation mit Patientenserum eine cellulär-cytoplasmatische Fluorescenz mit Anti-Komplement von subepithelial und interepithelial gelegenen Zellen. Die Befunde werden im Sinne eines hyperreaktiven Vorganges, der möglicherweise zur Induktion eines cellulären Immunmechanismus geführt hat, diskutiert.
    Notes: Summary An unusual course of Whipple's disease is reported. All clinical symptoms disappear with antibiotic therapy. Multiple control biopsies show a high grade and progressive collagen formation of the stratum proprium mucosae which takes places especially in the pericellular region and near the epithelial basal membrane. The number of lymphocytes, plasma cells and interepithelial lymphoid round cells is increased considerably. Immunologically the serum complement (C3-fraction) is decreased. Immunohistologically subepithelially and interepithelialy situated cells are found after incubation with the patients serum showing a cellular-cytoplasmatic fluorescence with anti-complement. These findings are discussed as a hyperreactive mechanism possibly leading to induction of a cellular immune process.

    Androgen-Sterilisierung der juvenilen weiblichen Ratte nach Behandlung mit humanem Chorion-Gonadotropin (HCG) (1971)

    Description / Table of Contents: Zusammenfassung Weibliche Sprague-Dawley-Ratten wurden vom 1.–14. Lebenstag mit täglichen HCG-Injektionen behandelt und erhielten am 15. Lebenstag 50 μg Testosteronpropionat injiziert. Kontrolltiere erhielten nur HCG vom 1.–14. Tag oder eine Testosteronpropionat-Injektion am 15. Lebenstag. HCG-Vorbehandlung mit anschließender Testosterongabe erzeugte in allen Fällen eine konstante Verhornung des Vaginalepithels sowie polycystische Ovarien ohne Corpora lutea. Tiere, denen täglich HCG während der ersten 14 Lebenstage verabfolgt wurde, oder die nur am 15. Lebenstage 50 μg Testosteronpropionat erhielten, entwickelten dagegen einen normalen 4tägigen Cyclus und normale Ovarien mit Corpora lutea aller Reifungsstadien. Es wird diskutiert, ob die Empfindlichkeit des Sexualzentrums auf Testosteron-Injektion am 15. Lebenstag auf einer direkten Wirkung von HCG auf die Differenzierung des Zwischenhirns oder auf eine indirekte Wirkung über eine geringe Hormonproduktion der durch HCG stimulierten Ovarien zurückzuführen ist.
    Notes: Summary By pretreatment of female Sprague-Dawley-rats with HCG from 1st to 14th day of life and a single injection of 50 μg testerone propionate (TP) on day 15th it was possible to suppress the development of a normal sexual cycle and produce a state of persistant vaginal cornification with polycystic ovaries without corpora lutea in all rats. Treatment with HCG alone or injection of TP at the 15th day of life without HCG-pretreatment did not prevent a normal sexual development in all animals. A direct inhibitory effect of HCG on the differentiation of the sexual center or an indirect one by a low production of hormones from the ovaries stimulated by HCG is discussed.

    Untersuchungen über den Energiestoffwechsel in isoliert perfundierten Ovarien des Menschen (1971)

    Description / Table of Contents: Zusammenfassung Sechs menschliche Ovarien, präovulatorisch entnommen mit Graafschen Follikeln, wurden isoliert in vitro mit einem rezirkulierenden, vollsynthetischen und hämoglobinfreien Medium über 3 Stunden perfundiert. Bestimmt wurde die Sauerstoffaufnahme der Ovarien sowie im Perfusionsmedium die Konzentrationsänderungen von Glucose, Pyruvat und Lactat. Nach Perfusionsschluß wurde zusätzlich im Gewebe der Ovarien der Gehalt an ATP, ADP, Glucose, Pyruvat und Lactat ermittelt. Die Ergebnisse werden ausführlich diskutiert und mit den Werten isoliert perfundierter Rinderovarien verglichen, sie zeigen, daß während der 3stündigen Perfusion ein funktionsfähiger Energiestoffwechsel aufrechterhalten werden kann.
    Notes: Summary Sex human ovaries with graafian follicles were perfused in a closed circulatory system, in vitro, with 100% synthetic hemoglobin-free medium. The oxygen uptake of the ovaries was determined and after the close of the perfusion another, determination followed: the concentration of ATP, ADP, glucose, pyruvate and lactate in the tissue. Changes in the level of glucose, pyruvate and lactate were ascertained additionally in the perfusion medium during its three hour circulation. The results were discussed and compared with the values from perfused bovine ovaries. The critical evaluation of the measurements confirms, that for a period of 3–4 hours, an energy metabolism which can be considered equivalent to its physiological counterpart is able to be maintained.

    Description / Table of Contents: Zusammenfassung An vier menschlichen Ovarien konntein vitro unter der Stimulation mit HCG/HMG eine Ovulation induziert und beobachtet werden. Die Ovarien wurden in einem rezirkulierenden System mit einem hämoglobinfreien, halbsynthetischen Medium perfundiert. Unter der Stimulation nahmen Atmung und Glykolyse bis zur Ruptur des Follikels um einen Faktor 2–3 zu. Dabei wurden aber −93% der freiwerdenden Energie aus dem aeroben Glucoseabbau gewonnen und nur −7% durch anaerobe Glykolyse. In der direkt präovulatorischen Phase konnte trotz Volumenzunahme des Follikels kein Anstieg des intrafollikulären hydrostatischen Druckes beobachtet werden. Der arterielle hydrostatische Druck dagegen zeigte 60–90 min zuvor einen wellenförmigen Anstieg bis zu 40 mmHg über den Normallevel, nach der Follikelruptur Abfall auf Ausgangswerte. Die Ergebnisse werden im Hinblick auf den Ovulationsmechanismus diskutiert.
    Notes: Summary An in vitro ovulation could be induced and observed in four human ovaries with Graafian follicle. Perfusion was carried out by means of a semi-synthetic medium which was free from haemoglobin in a closed recirculating system. During the stimulation by means of HCG/HMG (after the II. IRP a total of 22.9 I.U. LH/ml and 3 I.U. FSH/ml) an activation of respiration and glycolysis by a factor of 2–3up to the rupture of the follicle was observed. In this process 93% of the energy were released by the oxydative reduction of glucose and only about 7% by anaerobic glycolysis. 60–90 minutes before the rupture of the follicle an undulatory rise in the arterial hydrostatic pressure of up to 40 mmHg over the initial values was observed, although the outward conditions of perfusion were not altered, after the rupture a pressure drop to standard values. Apart from minor oscillations there was no increase in the intrafollicular pressure in spite of an increase in volume of the follicle, but only a decrease in pressure after the rupture of the follicle.
