1 Function of the Vascular Endothelium after Hypothermic Storage at Four Degrees Celsius in a Canine Tibial Perfusion Model. The Role of Adrenomedullin in Reperfusion Injury* by TEIJI KATO, ALLEN T. BISHOP, YUAN-KUN TU, and MICHAEL B. WOOD J Bone Joint Surg Am Volume 80(9):1341-1348 September 1, 1998 ©1998 by The Journal of Bone and Joint Surgery, Inc.

2 Fig. 1 Schematic representation showing the sequence of the infusion of the drugs in phase 1 and phase 2 of the study. t1, t2, and t3 indicate the times at which the initial norepinephrine dose-response curve was generated.
