    Notes: Summary Scatchard analysis of3H ouabain bound to isolated rectal gland cells as a function of increasing ouabain concentrations produced a concave curvilinear plot that was resolved into two specific sites with either a high (I) or low (II) affinity for ouabain. Cyclic cAMP/theophylline (±furosemide, 10−4 m) increased the amount of3H ouabain bound to the high-affinity site I. Vanadate, a phosphate congener which promotes formation of the ouabain-binding state of the enzyme, mimicked the effects of cAMP/theophylline at low concentrations of ouabain, suggesting that cAMP/theophylline increases binding to site I by enhancing the rate of turnover of resident enzyme. Enhanced86Rb uptake seen following cAMP/theophylline administration was primarily associated with increased flux through the high-affinity ouabain site, and this stimulation was not obliterated by the co-administration of furosemide. A model was presented which suggested the presence of two noninteracting pools of enzyme or isozymes which exhibit either a high or low affinity for ouabain. Cyclic AMP both stimulated turnover via site I, and modified the kinetics of binding of3H ouabain to site II. The (ave)K d of3H ouabain for site II was increased from 3.6 μm (controls) to 0.5 μm (cAMP/theophylline) and the Hill coefficient was modified from 0.45 (controls) to 1.12 (caMP/theophylline), suggesting a transition from a negative- to a noncooperative binding state. While furosemide reversed the effects of cAMP/theophylline on site II kinetics, it did not obliterate cAMP/theophylline effects on site I. This suggests that cAMP may alter the intrinsic turnover rate of this particular pool of Na,K-ATPase in shark rectal gland.

    Description / Table of Contents: Zusammenfassung In der vorliegenden Untersuchung wurden 294 Nachkommen (5–34 Jahre) essentieller Hypertoniker bezüglich Blutdruck, Renin-Angiotensin-Aldosteron-System and anderer kardiovaskulärer Risikofaktoren wie Glukose, Cholesterin und Triglyzeride untersucht und mit 122 Nachkommen (5–34 Jahre) normotoner Eltern verglichen. Dabei zeigte sich, daß Nachkommen essentieller Hypertoniker im Mittel statistisch signifikant höhere systolische und diastolische Blutdruckwerte zeigten als solche normotoner Eltern (p〈0,003 bzw. 0,005). Weiter ließ sich bei Kindern hypertoner Eltern im Mittel ein signifikant höheres Körpergewicht und ein größerer Body-Mass-Index beobachten als im Kontrollkollektiv (p〈0,006 bzw. 0,001). Mit Ausnahme statistisch signifikant niedrigerer Ruhe-Plasma-Aldosteronwerte (p〈0,002) bei Kindern essentieller Hypertoniker ließen sich zwischen beiden Kollektiven keine Unterschiede im Stimulationsaldosteron, in der Ruhe- und Stimulations-Plasma-Renin-Aktivität und im Plasmacortisol nachweisen. Ebenfalls zeigten die beiden Kollektive bezüglich der anderen untersuchten Parametern wie Kreatinin, Glukose, Cholesterin und Triglyzeride keine wesentlichen Unterschiede. Weiterhin wurden in der vorliegenden Untersuchung 41 hypertone Elternteile, 65 (normotone) Ehepartner von Hypertonikern und 47 (normotone) Eltern von Kontrollkindern untersucht. Erwarungsgemäß zeigten Hypertoniker statistisch signifikant höhere Blutdruckwerte als ihre Ehepartner und die Kontrolleltern (p〈0,001). Interessanterweise zeigten die hypertonen Eltern nicht nur einen höheren Body-Mass-Index als Kontrolleltern sondeern auch als Ehepartner (p〈0,01 bzw. 〈0,02). Diese Befunde stützen eine vorwiegend genetische Disposition als zugrundeliegende Ursache des höheren Körpergewichtsverhaltens und lassen eine vermehrte Nahrungsmittelaufnahme in Hypertonikerfamilien eher als unwahrscheinlich erscheinen. Die Ergebnisse der vorliegenden Studie legen es nahe, daß durch eine möglichst frühzeitige Kontrolle des Körpergewichtsverhaltens bei Nachkommen essentieller Hypertoniker ein Beitrag zur Primärprävention der Hochdruckkrankheit geleistet werden kann.
    Notes: Summary In the present study, blood pressure, the renin angiotensin aldosterone system, and other cardiovascular risk factors, such as glucose, cholesterine, and triglycerides, were investigated in 294 offspring of essential hypertensives (5–34 years) and in 122 children of normotensive parents (5–34 years). Offspring of essential hypertensives showed statistically significant higher systolic and diastolic blood pressure values than those of normotensive parents (p〈0.003, 〈0.005, respectively). Furthermore, in children of hypertensive parents a statistically significant higher body weight and body mass index than in controls could be observed (p〈0.006, 〈0.001, respectively). With the exception of statistically significant, lower mean supine plasma aldosterone values (p〈0.02) in children of hypertensive parents, no major differences between the two groups were seen in stimulated aldosterone, supine and stimulated plasma renin activity, and plasma cortisol. Furthermore, in the present study, 41 hypertensive parents, 65 (normotensive) spouses of hypertensives, and 47 (normotensive) parents of control children were investigated. As expected, hypertensive parents showed statistically significant higher blood pressure values than parents of control children and their spouses (p〈0.001). Interestingly, hypertensive parents had not only a higher body mass index than control parents but also than their spouses (p〈0.01 and 〈0.02, respectively). These findings support a genetic disposition as being the underlying cause of higher body weight in hypertensives and make it less probable that a higher food intake in hypertensive families is responsible for this phenomenon. The results of the present study indicate that early body weight control in children of hypertensive parents may be an important contribution to the prevention of hypertension.

    Notes: Summary In brain1, heart2 and kidney3, cell work in the absence of oxygen has been thought to precipitate anoxic damage by increasing the rate of depletion of cellular energy stores. In the medullary thick ascending limb of isolated perfused rat kidneys, however, reduction of ATP synthesis by a variety of mitochondrial or metabolic inhibitors caused ATP depletion comparable to that produced by oxygen deprivation but did not reproduce the lesions of anoxia. In these cells, unrestrained mitochondrial activity may be an important source of anoxic injury.

    Description / Table of Contents: Résumé Des études épidémiologiques ont clairement prouvé que certaines habitudes telles que celles relatives à la nourriture, par exemple, influencent de façon décisive le développement de l'athérosclérose; le rôle du milieu ambiant pour sa part semble plus difficile à déterminer. Il a toutefois été démontré que certaines substances trouvées dansl'eau pourraient jouer un rôle dans le développement des maladies cardiovasculaires. Nous ignorons tout quant aux facteurs responsables et leurs mécanismes. A ce jour l'on n'a pas encore réussi à séparer le facteur «climat» de celui de l'«eau». Même si lamonoxide de carbone dans l'air ambiant se révèle moins importante que celle du tabac pour la carboxy-hémoglobine, la pollution de l'air pourrait constituer un risque supplémentaire de conséquence particulièrement dans les zones industrielles ou pour les personnes atteintes d'athérosclérose latente.
    Abstract: Summary Epidemiological studies have clearly shown that the way of life, e. g. eating habits, have a decisive influence on diseases caused by atherosclerosis. It is less apparent whether and to what extent the physical environment may play an additional aetiological role. It was shown that there are factors in thewater which presumably affect these diseases but that the responsible substances and operative mechanisms remain to be defined. There is no certainty whether theweather exerts an influence which is independent of the «water factor». Even thoughcarbonmonoxide in the ambient air is less important than smoking in determining the carboxyhaemoglobin concentration in the blood, and consequent cardiovascular changes, air pollution constitutes an additional source of carbonmonoxide which may be a substantial hazard particularly in industry and for persons with latent atherosclerosis.
    Notes: Zusammenfassung Die Epidemiologie hat eindeutige Zusammenhänge zwischen Lebensgewohnheiten — z. B. der Ernährungsweise — und atherosklerosebedingten Krankheiten — aufgezeigt. Ob und inwieweit bei deren Genese die physische Umwelt eine zusätzliche ätiologische Rolle spielt, ist weniger klar. Faktoren imWasser haben wahrscheinlich einen Einfluss; allerdings sind die verantwortlichen Substanzen und Mechanismen noch nicht identifiziert. Unsicher ist, ob dasWetter einen vom «Wasserfaktor» unabhängigen Einfluss ausübt. DerLuftgehalt an Kohlenmonoxid trägt zwar weniger zum Anstieg des Carboxyhaemoglobins bei als das Rauchen; nichtsdestoweniger ist die Luftverschmutzung eine zusätzliche Quelle von CO, die insbesondere bei beruflich exponierten Gruppen und bei latenter Atherosklerose eine nicht zu vernachlässigende Gefährdung bedeuten kann.

    Description / Table of Contents: Summary An intervention study is being carried out in relation to the prevention of diseases caused by atherosclerosis, especially coronary heart disease. The purpose of the study is to test in one community whether an intensive health education program, including the media (newspapers, radio and educational materials) as well as more individual instruction (lecture, group discussions, courses, exhibitions, collaboration with organizations) can modify risk factors in the population through favorable changes in the mode of life. Another community without any programs serves as a control. Questionnaires are being sent and screening examinations are being carried out in random samples of both populations before and at the end of the educational campaign in order to evaluate its effect. The plan and methods of the study are being described and the distribution of risk factors, based on the first round of examinations, is presented. A second round of examinations is due after a 12 months interval.
    Notes: Résumé Cette étude concerne la prévention des maladies causées par l'athéro-sclérose, et principalement la maladie coronarienne. On a voulu savoir s'il était possible d'avoir une influence sur ces facteurs de risques en modifiant les habitudes de vie. Une certaine commune a fait l'objet d'une campagne intensive dans ce sens, tant au niveau des medias de masse que par l'insertion d'une équipe d'intervention dans les organisations locales pré-existantes. Une autre commune, n'ayant pas fait l'objet de cette intervention, est utilisée à des fins de contrôle. Des enquêtes et des examens préventifs sont faits dans les deux communes avant et après la période d'intervention, qui doit durer une année, et se terminer à l'automne 1975. Les résultats de la première série de ces examens ont été présentés dans cet exposé.

    Description / Table of Contents: Summary Switzerland ranks low in ischaemic heart disease mortality amongst the European countries. Evidence from field studies, however, would suggest that mortality is underestimated. Nevertheless, in Switzerland, like in France, the disease is probably rather less common than in some other comparable countries. The difference seems unexplained by the major, known risk factors, indicating a need for further research.
    Notes: Résumé La Suisse se range bas entre les pays Européens, concernant la mortalité des maladies cardiaques ischémiques. L'évidence d'études sur terrain, de toute faÇon, suggère que cette mortalité est sousestimée. Toutefois, en Suisse comme en France, la maladie est probablement moins d'ordre général qu'en certains autres pays comparables. La différence des chiffres ne semble s'expliquer par les facteurs de risques les plus importants. La nécessité de recherches ultérieures s'impose.
