title: [Dielectric behavior of isolated dog kidneys following storage preservation and subsequent autotransplantation].
abstract: A measurement of the vitality of kidney transplants before the implantation is not yet possible, however, criteria for the proof of anoxic and hypothermic lesions on isolate kidneys are known. With the investigation means of the passive-electric behaviour over the determination of the DK-course and the dispersion of epsilon' an original evaluation of the vitality is possible. With the help of the measurement of epsilon' in frequencies between 0.5 MHz and 3 MHz we establish the proportion of intact cell membranes and mitochondria. The modul M3 explains the distribution of relaxing structures. Our hitherto performed experiments have shown that by means of the observation of the two sizes a judgment of the vitality seems to be possible. Examinations on bastard dogs of either sex were performed. For the supplementation of the dielectric measurements in certain time intervals tissue samples of the preserved kidneys were investigated electron-microscopically.
