    Description / Table of Contents: Summary Percutaneous transluminal dilatation of a left sided renal artery stenosis was performed in a 61 year old patient with hypertension. Biochemical and hemodynamic activity of the renal artery stenosis was demonstrated by measurement of renal venous renin-activity and determination of renal plasma flow and of pre- and poststenotic blood pressure values. Shortly after the dilatation procedure hypertension disappeared and renal plasma flow increased. The described procedure might be an alternative method to renal vascular surgery.
    Notes: Zusammenfassung Bei einem 61jährigen Patienten mit renovasculärer Hypertonie bei linksseitiger arteriosklerotischer Nierenarterienstenose wurde eine perkutane transluminale Dilatation der Stenose vorgenommen. Die biochemische und hämodynamische Aktivität der Nierenarterienstenose wurde durch Messung der Plasmareninaktivität im Nierenvenenblut, Bestimmung des renalen Plasmaflusses und der prä- und poststenotischen Blutdruckwerte in der Nierenarterie belegt. Kurz nach der Dilatation der Stenose normalisierte sich der Blutdruck, und es kam zu einem Anstieg des renalen Plasmaflusses. Weitere Untersuchungen werden zeigen, ob die beschriebene Methode eine Alternative zur operativen Korrektur der Nierenarterienstenose bietet.

    Notes: Abstract Concentration factors (CF) of 54Mn for three aquatic species: green algae (Protococcoidal chlorella), Daphnia magna, and fathead minnows (Pimephales promelas) were determined following direct exposure to the isotope in solution. The maximum accumulation (CF = 911) in P. chlorella was reached at 48 hours of exposure; the maximum uptake (CF = 65) in Daphnia was reached at 8 hours of exposure; and the maximum accumulation (CF = 22.6) in fathead minnows was at 128 hours of exposure. The data indicate that 54Mn accumulation decreases with ascent up a theoretical aquatic food chain when water is the only source of contamination.
