2. Fig. 1
Survival after ischemia-reperfusion lung injury and the effect of deflation. Survival is decreased due to increased lung injury in animals treated with 4 hours of ischemia and, to a greater degree, in animals treated with 2 hours of ischemia while the lung was atelectatic.

3. Fig. 2
Ischemia-reperfusion injury increases pulmonary major histocompatibility complex expression. At 9 days after injury there is a significant increase in binding of radiolabeled anti-class II antibody to the injured left lung compared with the nonischemic right lung (n = 5 in all groups). (*p < 0.01 by analysis of variance compared with normal left lung and also by paired t test compared with matched nonischemic right lungs.) (CPM = counts per minute.)

4. Fig. 3
Duration of ischemia increases the degree of major histocompatibility complex expression. Significant increases in binding of radiolabeled anti-class II antibody are seen after 4 hours of ischemia (*p < 0.05), whereas lesser increases are seen after 2 hours of ischemia in the inflated state (n = 5 in all groups). (CPM = counts per minute.)

5. Fig. 4
Deflation during ischemia augments increased class II expression. There is significant binding of anti-class II antibody to the left lung after atelectatic injury, which is larger and more significant than after 2 hours of inflated ischemia (n = 5 in all groups). (CPM = counts per minute; *p = by analysis of variance compared with normal left lung; **p = )

6. Fig. 5
Allostimulation acts in combination with ischemia to increase class II major histocompatibility complex expression. Binding of radiolabeled anti-class II antibody is much greater after ischemia with concurrent allostimulation with Lewis mononuclear cells than after either ischemia alone or sham ischemia and allostimulation (n = 5 in all groups). (*p = by analysis of variance compared with normal left lung; **p = by paired t test compared with matched right lung and p = by analysis of variance compared with normal left lung.)

7. Fig. 6
Effect of allostimulation is not due to graft-versus-host disease. Similar large increases are seen in class II expression after allostimulation with either Lewis or Lewis X Brown Norway F1 mononuclear cells and 2 hours of ischemia followed by 9 days of reperfusion (n = 5 in all groups except where indicated). (*p = by analysis of variance compared with normal left lung; **p = by paired t test over matched right lung and p < by analysis of variance compared with normal left lung.)
