    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: 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 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.

    Notes: Abstract A patient with unilateral preauricular appendages and occipital mass is described who died on the fifth day of life. An autopsy demonstrated congenital megabladder and megaureters and dysplastic kidneys. The neuropathological examination revealed cranium bifidum in the occipital region, defective posterior arch of the Cl vertebral body, agenesis of vermis and a large cerebellocele. It is suggested that some patients with the Goldenhar-Gorlin syndrome may have prominent central nervous system involvement in spite of only relatively slight facial involvement.
