    Description / Table of Contents: Zusammenfassung Bei normotensiven und renal hypertensiven Ratten, die kochsalzarm oder kochsalznormal ernährt wurden, wurde der Effekt des Cyclooxygenasehemmers Indomethacin (3,4 mg/kg/24 h) auf den systolischen Blutdruck und die Plasma-Renin-Aktivität untersucht. Indometacin reduzierte die Plasma-Renin-Aktivität in kochsalzarm und kochsalznormal ernährten, normotensiven und hypertensiven Tieren. Darüberhinaus erniedrigte Indomethacin den systolischen Blutdruck in salz-arm ernährten Ratten, erhöhte jedoch den Blutdruck in salz-normal ernährten Tieren. Diese Befunde lassen vermuten, daß der Effekt von Indomethacin auf den Blutdruck von Ratten vom Extrazellulärvolumen und der Plasma-Renin-Aktivität abhängt.
    Notes: Summary The effect of the cyclooxygenase inhibitor indomethacin (3.4 mg/kg/24 hr) on systolic blood pressure (PB) and plasma-renin-activity (PRA) was evaluated in normotensive and renovascular hypertensive rats receiving either a normal or low salt diet. Indomethacin reduced PRA in normal and hypertensive animals on both low and normal salt intake. Indomethacin furthermore, decreased BP in animals on low sodium diet but increased PB in sodium repleted rats. These data suggest that the effect of indomethacin on rat BP may depend on the state of extracellular volume and PRA.

    Notes: Summary In order to improve dog kidney perfusion in situ with a protective solution, a perfusion catheter was constructed which allowed continuous pressure measurement in the center of the catheter tip during perfusion. Using this catheter, the equilibration of the extracellular space with a protective solution (HTK solution) was found to be pressure dependent. Continuous pressure and resistance control is therefore a prerequisite for reliable organ protection.

    Notes: Summary Kidneys were perfused either with Euro-Collinssolution or with HTK-solution of Bretschneider. The perfusion pressure as well as the perfusion flow were measured during a six-minute perfusion. The perfusion resistance was higher in Euro-Collins-kidneys than during HTK-perfusion. The venous outflow of the kidney as well as the ureteral outflow was measured during each minute of the perfusion and has analysed for osmolality, and for sodium and potassium concentrations. In Euro-Collins-kidneys a complete “equilibration” of the extracellular space was not achieved, while during HTK-perfusion concentrations in the venous as in the tubular outflow, similar to those in the HTK-solution itself, could be reached. At the end of the different perfusions, tissue was analysed for biochemical parameters such as ATP, ADP, AMP and lactate as well as for morphological features. Lactate had increased and ATP had decreased during perfusion with Euro-Collins-solution, while ATP had not changed and lactate had decreased during perfusion with HTK-solution. Normal glomerular, tubular and dilated vascular structures can be seen after HTK-perfusion, while a glomerular and vascular contraction takes place during Euro-Collins-perfusion.
