Medical Gases: A Novel Strategy for Attenuating Ischemia—Reperfusion Injury in Organ Transplantation?

Figure 4

Gross anatomy of lungs from rats 6 days after transplantation (arrow in a, b) and lungs from rats 6 days after transplantation which received CO at 500 ppm. In (a) and (c), the arrow points to the left transplanted lung; the right lung is the remaining native lung. Note that in the absence of CO, transplanted lungs were noted to be markedly hyperemic (a) and (b), which was notably absent in the transplanted lung exposed to CO (c) and (d). Scale bar, 1 cm [26].
