    Notes: Summary Intracellular activities of sodium and calcium were determined in red cells of patients with obesity. Compared to normal people mean intracellular sodium and calcium were higher in obese patients. However, increased intracellular sodium and calcium could only be observed in those patients with obesity suffering from hypertension or showing a familial disposition to hypertension. In contrast there was no difference in intracellular sodium and calcium between obese normotensives lacking a familial disposition to hypertension and normal people. Thus, our results suggest, that the observed variations in intracellular sodium and calcium in obesity are due to an enhanced blood pressure or a familial disposition to hypertension and not specific for obesity.

    Notes: BREUR, J.M.P.J., et al.: Pacemaker Therapy in Isolated Congenital Complete Atrioventricular Block. The aim of this study was to evaluate the effect of pacemaker (PM) therapy in patients with isolated congenital complete atrioventricular block (CCAVB). Patients with CCAVB eventually qualify for PM implantation, however, timing remains controversial. Retrospective evaluation of left ventricular end-diastolic diameter (LVEDD), shortening fraction (SF), and cardiothoracic ratio (CTR) in 149 CCAVB patients, before, at, and after PM implantation was carried out. LVEDD shows an average increase of 0.48%/month in non-PM patients, and an average decrease of 0.88%/month in PM patients. SF shows an average increase of 0.10%/month in non-PM, and an average decrease of 0.32%/month in PM patients. CTR shows an average increase of 0.02%/month in non-PM, and an average decrease of 0.19%/month in PM patients. The difference between the non-PM and PM groups is significant (P = 0.05) for all variables. Symptomatic patients show no significant change in LVEDD after PM therapy (from 66.5% before to 68.5% after PM therapy). Asymptomatic patients do show a significant (P 〈 0.001) decrease in LVEDD after PM therapy (from 78.4% before to 73.3% after PM therapy). CTR does not differ significantly between symptomatic and asymptomatic patients before PM therapy (58% and 57%, respectively). CTR does differ significantly (P 〈 0.001) between symptomatic and asymptomatic patients after PM therapy (52% and 48%, respectively). Heart size and SF are increased in most patients with isolated CCAVB. PM implantation is associated with a decrease in heart size and normalization of SF in most patients. Indications for PM therapy in children may require reevaluation in asymptomatic patients with increased cardiac size and decreased cardiac function.

    Description / Table of Contents: Summary Hospital diet is an essential part of modern therapy in all medical departments. It comprises both the so-called normal diets which are prepared according to modern nutritional knowledge, dietetic foods and the various forms of artificial nutrition (nutrient-defined and chemically defined diets, parenteral and combined nutrition, i.e. enterai and parenteral nutrition). The integration of nutritional therapeutic problems into the treatment of patients requires optimal scientific and practical forms of organisation of nutrition in the clinic. For that purpose, cooperation of clinical, technical, economic and pedagogic divisions is of prime importance. The organisation of patient nutrition in the St. Georg District Hospital in Leipzig is described as a feasible model.
    Notes: Zusammenfassung Die Krankenernährung ist ein wesentlicher Bestandteil einer modernen Therapie aller medizinischen Fachbereiche. Sie umfaßt sowohl die sogenannten Normalkostformen, die nach modernen ernährungswissenschaftlichen Kenntnissen hergestellt werden, die Diätkost und die verschiedenen Formen der künstlichen Ernährung (nährstoffdefinierte — und chemisch definierte Diäten, parenterale und Kombinationsernährung, d. h. enterai und parenteral). Die Einbeziehung der ernährungstherapeutischen Prinzipien in den Behandlungsplan der Patienten erfordert wissenschaftlich und praktisch optimale Organitionsformen der Krankenernährung. Dafür ist die Zusammenarbeit klinischer, technisch-wirtschaftlicher und pädagogischer Disziplinen Voraussetzung. Als praktikables Modell wird die Organisation der Krankenernährung im Bezirkskrankenhaus St. Georg Leipzig beschrieben.

    Notes: Zusammenfassung Wie sich aus einem großen, statistisch bearbeiteten klinischen Material ergibt, sprechen hohe Basophilenwerte eindeutig gegen eine Hyperthyreose und erniedrigte Basophilenwerte eindeutig gegen ein Myxödem. Auf Grund der Beeinflussung der Basophilenzahl durch außerhalb der Schilddrüsenwirkung gelegene Faktoren sind jedoch niedere Basophilenwerte zur Stellung der Hyperthyreosendiagnose bzw. erhöhte Basophilenwerte zur Stellung der Myxödemdiagnose nur beschränkt zu gebrauchen. Die Bestimmung der Basophilenzahl scheint zur Beurteilung des Therapieerfolges brauchbar.

    Morphology, flow regimes, and filtering rates of Daphnia, Ceriodaphnia, and Bosmina fed natural bacteria (1983)

    Notes: Summary Body size is the best overall indicator of the abilities of the cladocerans Daphnia magna, D. parvula, Ceriodaphnia lacustris and Bosmina longirostris to filter natural bacteria (〈1.0 μm). However, species differences exist which cannot be inferred from differences in size, behavior, or morphology alone. The relationship between filtering rate (FR in ml animal-1h-1) and body length (L in mm) for the cladocerans studied can be described by the power function: $$\begin{gathered} FR = 0.538 L^{1.545} \hfill \\ (r^2 = 0.88, F = 168.54, P 〈 0.001). \hfill \\ \end{gathered}$$ In D. parvula, algal filtering rates are higher and increase more rapidly with increasing body size than do bacterial filtering rates which are 26 to 33% of algal rates. This suggests that different processes may be involved in the capture of these ultrafine particles and that ultrafine particle capture efficiency decreases with increasing body size within a species. Weight specific filtering rates (in μl μg dry wt-1h-1) have a strong negative relationship to body size and show species specific differences. Appendage beat rates intersetular distances, setule diameter, appendage, area, % open space on the filtering appendage, Reynolds number, and boundary layer thickness do not provide simple predictions of bacterial filtering rates for the cladocerans studied. Filtering rates on cultured laboratory bacteria and algae may not indicate filtering rates on natural bacterioplankton because of differences in bacterial size, motility, and surface properties. Uptake of ultrafine particles may be enhanced by the presence of larger, more readily filtered particles through a “piggybacking” phenomenon.

    Häufigkeit und Bedeutung von Nierenarterienstenosen bei Patienten mit peripherer arterieller Verschlußkrankheit (1983)

    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.

    Notes: Summary In aortic smooth muscle cells from spontaneously hypertensive and normotensive rats, which were separated from the blood vessels by enzymatic digestion, intracellular Na+ and Ca2+ activities were measured. The determinations were made by ion-selective electrodes. In smooth muscle cells from spontaneously hypertensive rats intracellular Na+ and Ca2+ activities were elevated as compared to cells from normotensive rats (P〈0.001 for Na+ andP〈0.01 for Ca2+). Since in cultured aortic smooth muscle cells from spontaneously hypertensive rats intracellular Ca2+ is known to be not significantly increased, primarily humoral factors may account for the changes in intracellular Ca2+ reported.

    Notes: Summary To study the mechanisms by which K+ influences vascular tone in hypertension, spontaneously hypertensive and normotensive rats were examined during an oral K+ load. There was a marked decrease in blood pressure in spontaneously hypertensive but not in normotensive rats. Intraerythrocytic K+ concentration and activity increased in normotensive but not in spontaneously hypertensive rats. Intraerythrocytic Na+ concentration and activity declined in both strains, the decrease in Na+ activity being more prominent in spontaneously hypertensive rats (P〈0.05). Intraerythrocytic Ca2+ activity decreased in spontaneously hypertensive rats (P〈0.01) but not in normotensive rats. In both strains plasma aldosterone concentration increased during K+ load, the plasma renin activity being suppressed. The basal levels of plasma aldosterone in spontaneously hypertensive rats exceeded those in normotensive rats. It is concluded that intraerythrocytic Ca2+, and to a lesser extent Na+, correlate best with the blood pressure changes. These ionic changes may be mediated by hormonal factors. The significance of the elevated plasma aldosterone levels has not yet been entirely clarified.
