    Description / Table of Contents: Zusammenfassung Um das dynamische Sekretionsverhalten von PRL und TSH im TRH-Test und die Schilddrüsenfunktion bei gutartigen Brustdrüsenerkrankungen zu untersuchen, wurden 13 Patientinnen mit Mastodynie, 15 Patientinnen mit isolierter Galaktorrhoe, 6 Patientinnen mit diffuser Mammahypertrophie, sowie 5 Patientinnen mit großen Fibroadenomen in diese Studie aufgenommen. 11 gesunde Frauen wurden als Kontrollpersonen gegenübergestellt. PRL und TSH wurden vor und nach Injektion von 0,2 mg TRH gemessen. Des weiteren wurden Thyroxin (T4), Trijodthyronin (T3), und Thyroxinbindendes Globulin (TBG) bestimmt. Folgende Ergebnisse wurden erzielt: Alle untersuchten Patientinnen hatten im Vergleich zu den Kontrollen leicht, aber nicht signifikant erhöhte PRL Basisspiegel. Die PRL Antworten im TRH-Test lagen signifikant über denen der Kontrollen. Die peripheren Schilddrüsenhormonspiegel lagen bei den Kontrollen im Normbereich, ebenso TSH und TBG. Patientinnen mit Mastodynie und isolierter Galaktorrhoe zeigten eine Hormonokonstellation, wie sie bei blander endemischer Struma (relativ niedrige T4-Spiegel und relativ erhöhte T3-Spiegel) bekannt sind. Die Mittelwerte der TSH-Antworten im TRH-Test erreichten die obere Normgrenze und lagen signifikant über den Werten der Kontrollpersonen. Bei Mastodyniepatienten überschritt der mittlere TBG-Wert den der Kontrollpersonen. Patientinnen mit Mammahypertrophie wiesen Werte wie bei subklinischer Hypothyreoase auf: Grenzwertig erhöhte mittlere TSH-Antwort nach TRH-Stimulation, grenzwertig niedrige T4- und nicht erhöhte T3-Werte. Die Schilddrüsenhormon-Parameter der Patientinnen mit Fibroadenomen waren nicht signifikant von den Kontrollen unterschieden. Die vorliegenden Ergebnisse zeigen, daß die untersuchten Patientinnen eine erhöhte Ansprechbarkeit der PRL-bildenden Zellen auf TRH-Stimulation haben, was möglicherweise einen Faktor bei der Entstehung einer gutartigen Brustdrüsenerkrankung darstellt. Die Schilddrüsen-Funktionstests bei diesen Patientinnen zeigen das Bild wie bei einer blanden Struma bzw. einer subklinischen Hypothyreose.
    Notes: Summary The dynamic secretion of prolactin and TSH as well as the thyroid function were studied in patients with benign breast disease. The study included 13 patients with mastodynia, 15 patients with isolated galactorrhea, 6 patients with breast hypertrophy and 5 patients with fibroadenomata. Eleven healthy women served as controls. Prolactin and TSH were determined before and after TRH stimulation, using 0.2 mg TRH i.v. In addition thyroxine (T4), trijodthyronine (T3) and thyroxin-binding-globulin (TBG) were estimated. The following results were obtained: Basal prolactin levels were slightly but not significantly elevated in all patients studied. Maximal prolactin response to TRH was significantly greater as compared to the controls. TSH, T4, T3, and TBG-levels in the controls were within the normal range, while mastodynia and galactorrhea patients exhibited hormone patterns as known from endemic goiter (increased T3- and relatively low T4-levels). Mean TSH-responses reached the upper limit of the normal range. Mean TBG-levels in mastodynia patients exceeded the levels of the controls. In patients with breast hypertrophy thyroid hormone status indicated borderline hypothyroidism (borderline T4- and normal T3-levels, mean TSH-response slightly elevated to TRH). TSH secretion and thyroid function in patients with fibroadenomata did not differ from the controls. The presented data indicate an increased sensitivity of the lactotrophs representing possibly an important factor in the development of these benign breast diseases. The thyroid function tests in these patients revealed patterns known from endemic goiter and borderline hypothyroidism respectively.

    Description / Table of Contents: Summary Isolated pig livers are perfused with preserved human blood via a pump oxygenator under normothermic conditions. Depending on the duration of perfusion up to six hours a significant increase of intracellular liver encymes in the perfusion fluid can be observed. Bilirubin is excreted via the bile, but a simultaneous increase of bilirubin in the perfusion circuit can be monitored, which might indicate the ability of the liver to synthesise bilirubin through the break down of hemoglobin. The mobilisation of glycogen in the liver during the perfusion can be observed, as well as an excretion of cholesterol via the bile. The higher pH of the bile compared to the perfusion fluid further indicates the ability of the liver to excrete alkaline products through the bile.
    Notes: Zusammenfassung Isolierte Schweinelebern werden mittels eines Pumpoxygenators mit menschlichem Konservenblut über einen Zeitraum von 3 bzw. 6 Std in Normothermie und unter blutgasanalytischer Kontrolle perfundiert. Dabei kommt es zu einem deutlichen Aktivitätsanstieg der Zellenzyme im Perfusionsblut, was für eine Leberzellschädigung spricht. Bilirubin wird während der Perfusion in zunehmendem Maß über die Galle ausgeschieden und auch der Bilirubinspiegel im Blut steigt gering an, so daß die Bildung von Bilirubin durch Abbau des Hämoglobins in der Leber angenommen wird. Während der Perfusion kommt es zu einer Glykogenmobilisierung in der Leber. Die Ausscheidung von Cholesterin und alkalischer Phosphatase über die Galle ist zu Beginn reichlich und nimmt während der Perfusion ab. Die Galle ist deutlich alkalischer als das Perfusionsblut, was für die Fähigkeit der Leber spricht, alkalische Valenzen über die Galle zu eliminieren.

    Notes: Abstract Objective To investigate whether determination of right ventricular end-diastolic volume (RVEDV) and right ventricular ejection fraction (RVEF) can be performed with reasonable accuracy and reproducibility using a conventional slow response thermistor pulmonary artery catheter (CPAC) applying an adaptive algorithm. Design To study RVEDV and RVEF simultaneously with pulmonary artery catheters equipped with slow and fast response thermistors (FRPAC) under a broad range of cardiac output. Setting Laboratory of Institute of Experimental Surgery, Technical University. Animals 11 anaesthetised piglets. Interventions Hypovolemia (V−) was induced by withdrawal of blood up to 50 ml/kg, hypervolemia (V+) was produced by retransfusing blood and adding up to 30 ml/kg hydroxyethyl starch. In 5 animals in phases V−and V+ beta-adrenergic stimulation was achieved with dobutamine. Finally pulmonary artery hypertension was induced by infusion of small air bubbles. Measurements and results Cardiac output (CO), RVEDV and RVEF were determined simultaneously with FRPAC and CPAC placed in the same pulmonary artery branch. Measurements were repeated 8 times sequentially in steady state normovolemia. A total of 130 measurements could be analysed. The coefficient of variation was 6.7±4.2 for CO(FRPAC) and 4.6±1.7% for CO(CPAC); for RVEF it was 9.7±6.2% (FRPAC) and 9.9±3.9% (CPAC); for RVEDV it was 11.6±4.8% (FRPAC) and 8.54±3.2 (CPAC). Mean difference (bias) was 0.06±0.39 l/min for CO measured with both methods, 19±35 ml for RVEDV and −3.3±6.5% for RVEF. CO(CPAC) displayed a strong correlation to CO(FRPAC) (R=0.97,p=0.001) as well as RVEF (R for RVEF(CPAC) versus RVEF(FRPAC)=0.90,p=0.001). R for RVEDV(CPAC) versus RVEDV(FRPAC) was 0.67,p=0.001. We conclude that this animal study demonstrates good agreement between RVEF and RVEDV obtained with catheters equipped with a fast response thermistor or with a conventional slow response thermistor allowing accurate monitoring of right ventricular function with a conventional pulmonary artery catheter.

    Notes: —Concentration gradients for protein, lysine and methionine, and antitryptic activity were established in the cotyledons of two representative varieties of oil and grain legumes. Antitryptic activity in the separated cotyledons does not invariably follow the protein-distribution pattern.
