    Notes: Human lymphocytes alloactivated in vitro were cloned by limiting dilution in the presence of filler cells and interleukin 2 (IL 2)-containing supernatants of phytohaemagglutinin-stimulated lymphocytes. Clones with allospecific proliferative reactivity (PLT clones), measured by tritiated thymidine (3H-TdR) incorporation, were selected for extensive IL 2-dependent expansion. The cloned lines had finite lifespans, ranging from an estimated minimum of 28 to 〉 65 doublings. Function as PLT reagents, however, was retained in all cases for only an estimated 30 cell doublings. This apparent cessation of function was not caused by loss of the ability to metabolize thymidine, since lines continuing to grow for 〉 30 doublings still incorporated 3H-TdR in the presence of IL 2. An altered requirement for stimulating antigen (number of stimulating cells), or altered response kinetics, did not contribute to loss of PLT function. Exogenous IL 2 added during restimulation to responders previously ‘rested’ overnight without IL 2 did not restore the response. Thus, under present experimental conditions, functional lifespans of cloned PLT reagents appear fixed at ˜ 30 cell doublings.

    Notes: 1. The effect on renal function in sheep of inhibiting converting enzyme with captopril was examined before and after 5 days ACTH administration.2. Glomerular filtration rate, effective renal plasma flow, effective renal blood flow, mean arterial pressure and plasma sodium were all significantly incereased by ACTH treatment and plasma potassium was decreased. Captopril (20 mg i.v.) had no effect on renal function or blood pressure before or after ACTH treatment, although urinary potassium excretion decreased following captopril on day 6 of ACTH treatment.3. The increase in glomerular filtration rate and effective renal plasma flow seen with ACTH treatment in sheep does not appear to be mediated by the renin-angiotensin system.

    Description / Table of Contents: Summary In a wild boar enclosure in Austria, one individual several years old was observed smell marking and defending food. Apples were smell marked with urine and saliva. Young animals did not eat this food after having tested it by sniffing, although the marking ♂ did. The wild boar defended his feeding ground against men. In the process, he showed in a weaker or ritualised form behavioural patterns from the innate characteristics of parading, threatening and fighting. In addition, there is a report of an old boar in which acoustic impulses (the noises of a food container being used by another boar) triggered off a demonstration of rank and appropriation at the feeding ground. This trigger was more forceful than „avoidance of the enemy“. Mention is made of a case of imitation and learning in the overcoming of an obstacle.
    Abstract: Résumé Dans un parc à sangliers situé en Autriche un sanglier mâle adulte a été observé lorsqu'il procédait à des marquages olfactifs et lorsqu'il défendait sa nourriture. Des pommes furent marquées olfactivement au moyen d'urine et de salive. Contrairement au mâle en question, des sujets juvéniles n'ont pas absorbé cette nourriture apreast en avoir goûté par voie olfactive. Le verrat défendit son lieu de nourrissage contre les humains. A cette occasion il manifesta, sous une forme atténuée ou ritualisée, un comportement spécifique de défi, de menace et de combat. On fait également état d'une démonstration de rang social et d'appropriation sur une aire de nourrissage par un sanglier mâle âgé déclenchée par des stimuli acoustiques simulant le bruit provoqué par l'utilisation de mangeoires par d'autres sangliers. Ce déclencheur était plus puissant que l'„évitement d'un ennemi“. On signale un cas d'imitation et d'apprentissage lors du franchissement d'un obstacle.
    Notes: Zusammenfassung In einem österreichischen Wildschweingatter wurde ein mehrjähriger Keiler beim Duftmarkieren und Verteidigen von Futter beobachtet. Mit Harn und Speichel wurden Äpfel geruchlich markiert. Jungtiere haben dieses Futter nicht verzehrt, nachdem sie es olfaktorisch geprüft hatten, wohl aber das markierende ♂. Gegenüber Menschen verteidigte der Keiler seinen Futterplatz. Dabei zeigte er in abgeschwächter od. ritualisierter Form Verhaltensweisen aus dem innerartlichen Imponier-, Droh- und Kampfverhalten. Es wird ferner berichtet über einen alten Keiler, bei dem akustische Reize, die Geräusche eines von anderen Wildschweinen benutzten Futterbehälters, eine Rang- und Inbesitznahmedemonstration am Futterplatz auslösten. Dieser Auslöser war stärker als die „Feindvermeidung“. Ein Fall von Nachahmung und Lernen bei der Überwindung eines Hindernisses wird erwähnt.

    Notes: Abstract The characteristic ferroelectric dispersion of the complex dielectric constant of the ferroelectric AgNa(NO2)2 is measured as function of temperature and hydrostatic pressure. For the first time the temperature and pressure dependences of the static order parameter susceptibility and the order parameter relaxation time could be reproducibly determined. The results are interpreted in terms of a kinetic Ising model, whose parameters show a characteristic pressure dependence. The results are discussed on the basis of thermodynamic relations and related to the dynamical behaviour of other order-disorder ferroelectrics.

    Notes: Abstract The half-life of the 1/2− isomer in89Mo has been determined in an experiment where an enriched92Mo target was irradiated by 350 or 700 ms bursts of 60 MeV protons. Analysis of the gamma-ray spectra collected as a function of time between irradiations revealed gamma rays at 118.8 and 268.5 keV decaying with a 190±15 ms half-life. The hindrance ofE3 transitions inN=47 andZ=47 nuclides is discussed.

    Notes: Zusammenfassung 1. Es wird über chemische Eiteruntersuchungen berichtet und dabei hervorgehoben, daß Blutzucker und Milchsäure mit zunehmendem Alter des Eiters schwinden. 2. Damit geht der Schwund des glykolytischen und diastatischen Fermentes einher. 3. Mit Zunahme der Zeichen der Entzündung geht eine Erhöhung des Kaliumgehaltes einher.

    Notes: Zusammenfassung 1. Es wurde die Umlagerungsfähigkeit der Carotine als der Vorstufen zum Vitamin A unter verschiedenen Bedingungen der Leberschädigung verfolgt. 2. Im Stadium der vollen avitaminotischen Störung kann aus dem Provitamin das Vitamin A nicht mehr gebildet werden, Vitamin A selbst dagegen wird gut verwertet und gespeichert. 3. Die thyreogene Leberschädigung geht mit Vitamin A-Verlust einher. Dieser Verlust beruht auf einem stark erhöhten Vitamin A-Umsatz und -Verbrauch, dagegen nicht auf einer mangelnden Umlagerungsfähigkeit. 4. Im Zustand der thyreogenen Leberschädigung ist die Verwertungs- und Speicherungsfähigkeit des Vitamin A achtmal höher als die seiner Vorstufen, der Carotine. 5. Der Vitamin A-Umsatz ist an den Glykogenumsatz der Leber gekoppelt.

    Notes: Summary In order to evaluate the prevalence of renal artery stenoses and the coincidence with hypertension, in this study 110 patients (24 women, 86 men, mean age 63.2±8.6 years) underwent retrograde aortography for reason of symptomatic arteriosclerosis obliterans of the lower limb arteries. In 18 (16.4%) patients renal artery stenoses by which the lumen was narrowed for more than 30% and in 2 (1.8%) patients occlusions of one renal artery were found, all of which seemed to be of arteriosclerotic origin. 12 (60%) patients with renal artery stenoses or occlusions showed arterial hypertension (RR 171±33/94±16 mmHg) inspite of adequate antihypertensive medication, 8 were normotensive even though renal artery stenoses were found angiographically. On the other hand 30 (33%) of the 90 patients without renal artery stenoses were hypertensive (RR 165±15/93±9 mmHg). These data support the observation that renal artery stenoses must not result in hypertension, but clearly indicate the higher prevalence of hypertension in patients with renal artery stenoses or occlusions. With regard to the low-risk procedure of percutaneous transluminal dilatation of renal arteries, it seems to be valuable for hypertensive patients to include renovasography into the angiographic evaluation of symptomatic lower limb arteriosclerosis.
