    Notes: Abstract  The sensory innervation of the hard palate of the rhesus monkey was studied by light and electron microscopy. The mucosa of the hard palate is subject to a particularly heavy mechanical load requiring functional specialisation of the horny epithelium in the form of thickenings – the papilla incisiva and eight pairs of rugae palatinae. A thin layer of firm connective tissue (lamina propria) attaches the mucosa to the periost of the hard palate. Sensory nerve fibres were found most abundantly in the papilla incisiva and first rugae palatinae. Their number decreases in an aboral direction. Five types of sensory nerve endings were found. Free nerve endings were ubiquitous in the epithelium and lamina propria. Merkel nerve endings were found in the basal layer of the epithelium of the papilla incisiva and rugae palatinae. Meissner corpuscles were located in the connective tissue between epithelial pegs, while lamellated corpuscles were seen below the epithelial pegs. Ruffini corpuscles were found in the deeper layer of the lamina propria. Thus, a variety of sensory nerve endings were found in the hard palate, especially in those areas that are in close contact with the tongue during chewing of food. This rich innervation suggests an important role in monitoring the mechanical properties of food and the position of the tongue.

    Description / Table of Contents: Summary The effect of angiotensin II (A II) on the release of catecholamines was examined on 6 anesthetized dogs. Subpressor (5 ng/kg/min) and high pressor doses (1000 ng/kg/min) of A II were infused into an internal carotid artery. While subpressor doses of A II caused no increase of the catecholamine excretion, both epinephrine and norepinephrine excretion increased considerably under pressor doses of A II. The increase of the epinephrine excretion was statistically significant (p〈0,05). Considering the partly contradictory results of other authors, the discussion deals mainly with problems of dose, mode and site of action of A II and the influence of anesthesia. Finally, a possible significance of our results for the pathogenesis of special types of arterial hypertension is discussed.
    Notes: Zusammenfassung Die Wirkung von Angiotensin II (A II) auf den Katecholaminhaushalt wurde an 6 narkotisierten Hunden geprüft. Dabei wurden subpressorische (5 ng/kg/min) und stark pressorische (1000 ng/kg/min) Angiotensin-Dosen, denen jeweils Infusionen von 0,9%igen NaCl-Lösungen vorausgingen, in die Arteria carotis interna infundiert. Während unter subpressorischen A II-Infusionen keine Steigerung der Katecholaminausscheidung beobachtet werden konnte, stieg die Adrenalin- und Noradrenalinexkretion unter der pressorischen A II-Gabe deutlich an. Die Erhöhung der Adrenalinausscheidung war dabei statistisch signifikant (p〈0,05). Die Ergebnisse werden im Zusammenhang mit den zum Teil unterschiedlichen Befunden anderer Autoren besprochen, wobei vor allem Fragen des Angriffspunktes und des Wirkungsmechanismus von A II, der A II-Dosierung und der Narkose erörtert werden. Schließlich wird diskutiert, welche Bedeutung die Befunde im Hinblick auf die Pathogenese besonderer Hypertonieformen besitzen können.

    Description / Table of Contents: Summary Two patients were submitted to a constant sodium diet and 3 mg d-aldosterone/day. One of them suffered from a craniopharyngeoma and pituitary insufficiency, the other one from Cushing's syndrome due to a local malignant chromophobe adenoma of the pituitary. The patient with Cushing's syndrome was studied after coagulation of the pituitary. Both showed the typical renal escape-phenomenon after a few days. These data suggest that the pituitary does not seem to be an important factor in the renal escape-phenomenon. The theories which could account for this phenomenon are discussed.
    Notes: Zusammenfassung Durch Gabe von 3 mg d-Aldosteron täglich i.m. unter gleichzeitiger Natriumbelastung konnte bei einem Patienten mit Kraniopharyngeom und Panhypopituitarismus sowie bei einer Patientin mit Cushing-Symptomatik bei einem lokal malignen chromophoben Hypophysenadenom nach Hypophysencoagulation zuerst eine positive Natriumbilanz und nach einigen Tagen das typische renale Escape-Phänomen hervorgerufen werden. Die menschliche Hypophyse scheint demnach nicht entscheidend am Zustandekommen des Escape-Phänomens beteiligt zu sein. Die Theorien, die heute zur Erklärung des Escape-Phänomens herangezogen werden können, werden diskutiert.

    Description / Table of Contents: Summary Determinations of the plasma renin activity (PRA) and the aldosterone excretion rate (AER) were carried out in two patients with idiopathic edema. The PRA basic values were found to be within normal range in both patients, while a large increase in the PRA resulted following stimulation through salt deprivation and orthostasis, as can be observed especially in renovascular and malignant hypertension. The AER were also normal and increased clearly only after administration of saluretics. The results are evaluated in view of the pathophysiological disturbances, which lay at the root of this particular form of edema. Furthermore, the other factors besides the renin-angiotensin-aldosterone-system are discussed, which can be regarded as responsible for the etiology or pathogenesis of the idiopathic edema.
    Notes: Zusammenfassung Bei 2 Patientinnen mit idiopathischen Ödemen wurden Bestimmungen der Plasmareninaktivität (PRA) und der Aldosteronexkretionsrate (AER) durchgeführt. Die PRA-Basiswerte lagen bei beiden Patientinnen im Normbereich, während nach Stimulation durch Salzentzug und Orthostase ein starker Anstieg der PRA erfolgte, wie man ihn vor allem bei der renovasculären und bei der malignen Hypertonie beobachten kann. Die AER waren ebenfalls normal und wurden nur nach Gaben von Saluretica deutlich erhöht. Die Befunde werden im Hinblick auf die pathophysiologischen Störungen erörtert, die dieser besonderen Ödemerkrankung zugrundeliegen. Weiterhin werden die Faktoren diskutiert, die neben dem Renin-Angiotensin-Aldosteron-System für die Ätiologie oder die Pathogenese der idiopathischen Ödeme als verantwortlich betrachtet werden.

    Description / Table of Contents: Summary The effect of hydrochlorothiazide on plasma renin activity (PRA) and aldosterone excretion rate (AER) were examined in 10 normal persons. At the same time, determinations of serum and urine electrolytes, of hematocrit and of fluid balance were carried out. In that group which recieved 50 mg hydrochlorothiazide (Esidrex®) daily for 7 days, the PRA rose significantly on the 2nd and 4th day and the AER on the 3rd day after the beginning of diuretic treatment. A decline to normal in both parameters set in on the 6th and 7th day, respectively. Considerable changes in serum electrolytes and hematocrit were not registered. The stimulation of the renin-angiotensin-aldosterone system (RAAS) could be correlated with elevated natriuresis and diuresis. Kaliuresis rose considerably as well so that the Na/K quotient in urine fell under 1. In that group which recieved 50 mg hydrochlorothiazide daily for a period of 6 weeks, no significant changes were noticed in PRA, AER, serum electrolytes or hematocrit after 2, 4 and 6 weeks of diuretic treatment. There was no development of secondary hyperaldosteronism under extended saluretic treatment. The effect of sodium restriction as well as saluretica-induced sodium excretion on the RAAS is discussed. Finally, the possibilities are discussed which can cause a retreat in stimulation of the RAAS despite extended treatment with diuretics.
    Notes: Zusammenfassung Die Wirkung von Hydrochlorothiazid auf die Plasma-Renin-Aktivität (PRA) und die Aldosteron-Exkretionsrate (AER) wird bei 10 Normalpersonen untersucht. Gleichzeitig werden Bestimmungen der Serum- und Urinelektrolyte, des Hämatokrits und der Flüssigkeitsbilanz durchgeführt. In derjenigen Gruppe, die während 7 Tagen täglich 50 mg Hydrochlorothiazid (Esidrex®) erhielt, steigen die PRA am 2. und 4. Tag und die AER am 3. Tag nach Beginn der Diuretikagabe signifikant an, während am 6. bzw. am 7. Tag ein Abfall beider Parameter zur Norm einsetzt. Wesentliche Änderungen der Serumelektrolyte und des Hämatokrits werden nicht registriert. Die Stimulation des Renin-Angiotensin-Aldosteron-Systems (RAAS) kann mit einer erhöhten Natriurese und Diurese korreliert werden. Die Kaliurese steigt ebenfalls deutlich an, so daß der Na/K-Quotient im Urin unter 1 abfällt. In derjenigen Gruppe, die während 6 Wochen täglich 50 mg Hydrochlorothiazid erhielt, werden nach 2, 4 und 6 Wochen der Diuretikaverabreichung keine signifikanten Veränderungen der PRA, AER, Serumelektrolyte und des Hämatokrits festgestellt. Es entwickelt sich demnach unter längerdauernden Saluretikagaben kein sekundärer Hyperaldosteronismus. Die Wirkung sowohl einer Natriumrestriktion als auch einer saluretikainduzierten Natriumexkretion auf das RAAS wird besprochen. Schließlich werden die Möglichkeiten diskutiert, die einen Rückgang der Stimulation des RAAS trotz andauernder Diuretikagaben bewirken können.
