title: [Kidney function parameters following ischemia stress using the Euro-Collins solution or the Bretschneider cardioplegic HTK solution].
abstract: Protection-methods, for an improvement of ischemic tolerance of the kidney, can be investigated by intraischemic analysis of metabolism and structure. A definite proof for the effectiveness of a protection method is only postischemic function in combination with postischemic structure-regeneration. For this reason postischemic function was chosen for examination of the protective ability of the Euro-Collins-solution and the HTK-solution during a two-hour reperfusion period. We perfused 57 dog kidneys either with the Euro-Collins- or with the HTK-solution prior to ischemia. Ischemia was 7, 60, 90 and 120 min after Euro-Collins-perfusion and 7, 120, 150 and 180 min after HTK-protection. The protected and ischemic kidneys were left in-situ; the mean ischemic temperature was therefore 20-25 degrees C for the shorter ischemic times and 30-34 degrees C for the longer ischemic times. We compared the protected and ischemic kidneys with 14 untreated kidneys (control). Postischemic renal blood flow (RBF) was measured by an electromagnetic flow probe; renal oxygen consumption (V02/min) was calculated by arterio-venous oxygen content difference and the renal blood flow. If urine could be collected, the glomerular filtration rate (GFR) was measured by an endogenous creatinine clearance. In Euro-Collins-protected kidneys after 60-120 min ischemia the RBF was after 15 min of reperfusion between 20 and 100 ml/min/100 g. After 30 min we got values of 100-200 ml/min/100 g. The V02/min, which was in the control kidneys between 5-6 ml/min/100 g, was about 2 ml/min/100 g.(ABSTRACT TRUNCATED AT 250 WORDS)
