Effects of limb IR with post-conditioning on the lung wet-to-dry (W/D) weight ratio after 120 min of reperfusion. Sham, IR, LIPC, and LIR indicate sham control, ischemic post-conditioning, limb IR with post conditioning, and limb ischemic-reperfusion, respectively. Data are mean ± S.D., n = 8 per group. **P < 0.01, IR versus Sham; *P < 0.01, LIPC versus IR.
