Mitochondrial complex activity in donor renal grafts, cold ischemia time, and recovery of graft function.

Indexed mitochondrial complex activities (MCAi) were determined in biopsies obtained from 52 donor kidneys at the end of cold ischemia (8-32 hr) to see if longer anoxia affected MCAi and accounted for the increased risk of delayed graft function (DGF) in recipients of grafts with longer cold ischemia time (CIT) or from non-heart-beating donors (NHBD). CITs were significantly different between those with and without DGF (P=0.02), being shorter in the latter, but MCAi were similar.
