    Notes: Abstract Physical exercise causes transient albuminuria. The mechanisms of postexercise albuminuria are not fully clarified but stimulation of the reninangiotensin system (RAS) probably plays a major role through intrarenal haemodynamic changes causing an elevated filtration pressure. In a randomised, double-blind, crossover study we compared the effects on urinary albumin excretion (UAE) of lisinopril (L) and atenolol (A) therapy, i.e. we aimed to investigate whether inhibition of the RAS or inhibition of β1-adrenoceptor-mediated effects of the sympathetic nervous system differed with regard to changes in UAE. Sixteen patients with uncomplicated primary hypertension were studied. Four standardised bicycle ergometer exercise tests were performed, before and after each active treatment period. UAE 30 min postexercise, determined by radioimmunoassay, was significantly lowered by both treatments: -278 μg·min-1 (L) and-199 μg·min-1 (A). The reduction of postexercise UAE achieved by treatment with the angiotensin-converting enzyme (ACE) inhibitor (L) was significantly greater than that achieved by the β1-selective adrenoceptor blocker treatment. Blood pressure (BP) at rest and during exercise were equally reduced by both drugs. In conclusion, this study showed that antihypertensive treatment with an ACE inhibitor was more effective in reducing exercise-induced albuminuria than a β1-selective adrenoceptor-blocking agent with a similar degree of BP reduction in patients with uncomplicated primary hypertension. This suggests that the RAS plays a major role in postexercise albuminuria in hypertensive subjects. The clinical significance of this finding, however, remains to be clarified.

    Notes: Neue Arbeiten über die Addition von Organozinn-hydriden an Verbindungen mit C=C, C≡C, C=O, C=N, N=N, NCO, NCS und NO-Gruppen werden zusammengefaßt, weitere Ergebnisse mitgeteilt. Die Reaktionen verlaufen meistens radikalisch, seltener polar und können durch Katalysatoren sehr beschleunigt werden. Organozinn-hydride sind starke Radikalfänger und üben auf den Zerfall von Radikalbildnern weitgehende Einflüsse aus.

    Notes: α-Carbonyl-Azoverbindungen wie Azodicarbonsäurediester, Diacyl-Azoverbindungen und Aryl-azo-carbonsäureester sind recht reaktionsfreudige Verbindungen. Sie addieren sich z. B. an Amine, Aromaten, Olefine, CH-acide Substanzen, Grignard- und Diazo-Verbindungen, Aldehyde, Ketone und Ketene. Dabei sind u. a. Triazane, Hydrazone, Oxadiazolin-, Azomethin-imin- und Diazetidin-Derivate zugänglich. α,α'-Dicarbonyl-Azoverbindungen gehören zu den besten Dienophilen.

    Notes: α-Carbonyl azo compounds such as diesters of azodicarboxylic acids, diacylazo compounds, and esters of arylazocarboxylic acids are highly reactive. They add e.g. to amines, aromatic compounds, olefins, CH acids, Grignard and diazo compounds, aldehydes, ketones, and ketenes. These reactions can be used for the preparation of triazanes, hydrazones, oxa-diazoline, azomethinimine, and diazetidine derivatives, etc. α,α′-Dicarbonyl azo compounds are among the strongest dienophiles known.
