D.A. Rorvik, J.J. Kelly, *D.H. Burns and C.H. Barlow  (1989)  Imaging cytochrome oxidation in hypothermically stored rat kidneys. IEEE/EMBS 11:622-623. A major concern in kidney transplant surgery is organ viability at the time of the operation. Using spectroscopic analysis of mitochondrial cytochrome oxidation-reduction states, respiratory integrity of hypothermically stored kidneys can be determined. A time-sharing fiberoptic spectrophotometer and a video-reflectance spectrometer have been constructed to trace the reflectance changes of cytochrome c and cytochrome aa3 in the kidney cortex.
