    Description / Table of Contents: Summary The effect of a 5 day ACTH test (40 U/24 h) on plasma aldosterone (aldo), deoxycorticosterone (DOC), plasma renin activity (PRA) and urinary excretion of aldosterone-pH1-conjugate (pH-1-aldo) and tetrahydro-DOC (TH-DOC) was investigated in 8 normotensive children (group I), 8 patients with hypertension of unknown origin (group II), and 4 hypertensive children with dexamethasone suppressible hyperaldosteronism (DSH) (group III). Changes in blood pressure and sodium balance were studied in all groups. Under baseline conditions there was no hormonal difference between group I and II. In contrast, the children in group III had a suppressed PRA and a 1.5–2 fold elevation of aldo and DOC. Plasma DOC and urinary THDOC increased continuously 10–50 fold in all groups during the ACTH test. Aldo rose transiently 2–4 fold on the first day of ACTH and fell subsequently below baseline levels in group I and II. The children with DSH (group III), however, showed an unusual, sustained aldo stimulation with ACTH. PRA decreased significantly after ACTH in group I and II. Sodium retention and an elevation of blood pressure were found in all groups during ACTH administration. The highest blood pressure rise was observed in group III (from 124/72 to 139/90 mm Hg). The blood pressure response to ACTH was partly sodium dependent. Although aldo and DOC and sodium retention may contribute to the ACTH induced blood pressure elevation, other factors must play a role.
    Notes: Zusammenfassung Der Einfluß einer 5tägigen ACTH-Behandlung (40 U/24 h) auf Plasma-Aldosteron (Aldo), Deoxycorticosteron (DOC), Plasma-Reninaktivität (PRA), auf die Ausscheidung des Aldosteron-pH-1 Conjugates (pH-1-aldo) und auf Tetrahydro-DOC (TH-DOC) wurde untersucht in Gruppe I: acht normotensiven Kindern; Gruppe II: acht Patienten mit Bluthochdruck unklarer Genese; Gruppe III: vier hypertensiven Kindern mit Dexamethason-supprimierbarem Hyperaldosteronismus (DSH). Änderungen des Blutdruckes und der Natriumbilanz wurden in allen Gruppen untersucht. Ohne Behandlung bestand kein Unterschied zwischen den Gruppen I und II. Die Kinder der Gruppe III hingegen zeigten erniedrigte PRA und eine 1,5–2fache Erhöhung des Aldo und DOC. Plasma-DOC und TH-DOC im Urin stiegen kontinuierlich auf das 10–50fache in allen Gruppen während des ACTH-Tests an. Aldo war am 1. Tag des Tests vorübergehend um das 2–4fache erhöht und fiel anschließend unter die Ausgangswerte in den Gruppen I und II. Die Kinder mit DSH (Gruppe III) zeigten eine ungewöhnliche, anhaltende Stimulation des Aldo unter ACTH-Behandlung. PRA war in den Gruppen I und II signifikant erniedrigt. Natriumretention und Anstieg des Blutdruckes wurden in allen Gruppen während des ACTH-Tests festgestellt. Die höchsten Blutdruckanstiege (von 125/72 auf 139/90) wurden in Gruppe III beobachtet. Das Ansprechen des Blutdruckes auf ACTH war zum Teil abhängig vom Natrium. Obgleich Aldo, DOC und Natriumretention wahrscheinlich zu dem ACTH-induzierten Blutdruckanstieg beitragen, müssen noch weitere Faktoren zu dessen Entstehung beitragen.

    Notes: Abstract This case report describes the delayed presentation of bilateral Morgagni herniae in a 4 1/2-year-old boy with Down's syndrome. The authors emphasize the difficulties in establishing the diagnosis, although ultrasonography appears to be valu‐able. A review of the literature suggests an association between Morgagni hernias and trisomy 21.

    Notes: Abstract Selaginella moratii W. Hagemann & W. Rauh, spec. nova, is described. The Madagascarian plant from Fianarantsoa has a strongly differentiated subterranean rhizome system with a dichocladial mother rhizome bearing anisotomous branch systems with tufted tubers. These rhizophore tubers are observed for the first time inSelaginella. The green photophilous aerial shoots are produced by unbranched subterranean runners. The plant is adapted to carpets ofColeochloa setifera lying on granite rocks. Within these carpets,Selaginella moratii is associated withDrosera, Genlisea, Xerophyta, Myriothamnus, Kalanchoë, Senecio, andAloë among others. The description of the unique plants ofSelaginella moratii Rauh & Hagemann is based on alcohol-fixed material collected in 1963 by the senior author. The largest plants from this material measured approximately 10 cm. It is unknown whether larger plants exist in nature. It must be stated that the collected material is incomplete in many respects. Thus, it does not permit a complete reconstruction of the growth form of the natural plants, and further, it turned out that some anatomical details could not be sufficiently cleared up. Due to the fact that, in the natural sites, plant collectors can see only the aerial shoot systems, which show no striking differences to other dorsiventral selaginellas, it happened that the species was overlooked. Also, since the collected material has not been described until now, the plant has not been rediscovered since the year of its first observation. Thus, a comprehensive comparative study of the living plants remains a desideratum.
