    Notes: Summary Antihypertensive therapy influences kidney function by different mechanisms depending on the mode of action of the drug used. The GFR is improved by calcium entry blockers and ACE inhibitors, unaffected by vasodilators, α-blockers and centrally acting sympatholytics and impaired by β-blockers. The same is true for renal blood flow and is due to changes of renal vascular resistance. Renal sodium excretion is impaired mostly by vasodilators, by α-blockers, sympatholytics and β-blockers; in contrast, calcium entry blockers and ACE inhibitors acutely induce natriuresis. The RAAS is stimulated by vasodilators, unaffected by α-blockers and sympatholytics and suppressed by β-blockers. Plasma catecholamines are stimulated by vasodilators and suppressed by centrally acting sympatholytics and unaffected by the others. Induction of acute renal functional impairment is reported for ACE inhibitors under conditions of compromised renal perfusion pressure such as in renal artery stenosis. These data from the literature reviewed are supported by our own experimental data on sodium balance under different drugs and micropuncture data in experimental renal artery stenosis. To achieve effective antihypertensive treatment with a low profile of side effects, careful monitoring of renal function seems to be mandatory.

    Description / Table of Contents: Zusammenfassung Die induktiv gekoppelte Plasma-Emissionsspektrometrie wird gegenwärtig zu einem wichtigen analytischen Werkzeug in Routinelaboratorien. Der Einsatz der ICP-Emissionsspektrometrie wird an den analytischen Anforderungen gemessen. Die simultane Bestimmung von Al, B, Cr, Cu und Mn in Abwasser oder Lösungen aus Stahlproben wird als Beispiel herangezogen. Die reellen Bestimmungsgrenzen für zahlreiche Elemente aus Stahl, die von dem eingesetzten Apparat und den Arbeitsbedingungen abhängen, werden mitgeteilt. Die wichtigsten Parameter wie Abstimmung zwischen Generator, Impedanzwandler und Spule, die Art des Zerstäubers, die Proben-Aerosolgasmenge und die Beobachtungshöhe im Plasma werden diskutiert.
    Notes: Abstract The inductively coupled plasma emission spectrometry is becoming a very important analytical tool in routine laboratories today. The application of ICP emission spectrometry in comparison to the analytical needs is described. The simultaneous determination of Al, B, Cr, Cu and Mn in waste water or steel solution is taken for example. The real limits of determination for several elements from steel samples depending on the applied ICP/spectrometer device and the working conditions are given. The most important parameters like tuning between generator, matchbox and coil, the kind of nebulizer, the sample flow gas rate and the observation height in the plasma are discussed.
