Objective: Operation on the infrarenal aorta could cause ischemic-reperfusion (IR) injury in local tissues and remote organs (e.g. the lung). We aim to explore the method of reducing lung ischemia-reperfusion damage after lower limb IR with post conditioning (LIPC). Methods: Bilateral lower limb ischemia was performed in Sprague-Dawley (SD) rats, and then animals were divided into 4 groups: IR-Sham-operated, IR, post conditioned-IR (LIPC) and bilateral lower limb ischemia (LIR). The serum free radical, histological changes, Wet/Dry (W/D) ratio, levels of TNF-alpha, IL-6, cytokines and chemokines were tested and compared. Results: Post-conditioning could ameliorate histological injuries in the lung when compared to IR group. The serum free radical is significantly lower in LIPC group than IR groups. W/D ratio in LIPC groups is significantly lower. LIPC also could reduce the expression of cytokines and chemokines. Conclusion: post conditioning could reduce long-term damages of the lung after lower limb ischemic-reperfusion injury.
