    Abstract:
    OBJECTIVE: To determine whether fructose-1,6-diphosphate (FDP) pretreatment can attenuate acute lung injury induced by ischemia-reperfusion in our isolated lung model in rats. DESIGN: Randomized, controlled study. SETTING: Animal care facility procedure room. SUBJECTS: Twenty-four adult male Sprague-Dawley rats each weighing 250-350 g. INTERVENTIONS: Typical acute lung injury in rats was induced successfully by 10 mins of hypoxia followed by 75 mins of ischemia and 50 mins of reperfusion. Ischemia-reperfusion significantly increased microvascular permeability as measured by the capillary filtration coefficient, lung weight gain, lung weight to body weight ratio, pulmonary arterial pressure, and protein concentration of bronchoalveolar lav-age fluid. MEASUREMENTS AND MAIN RESULTS: Pretreatment with FDP significantly attenuated the acute lung injury induced by ischemia-reperfusion as shown by a significant decrease in all of the assessed variables (p <.05 p <.001). The protective effect of FDP was nearly undetectable when promazine (an ecto-adenosine 5-triphosphatase inhibitor) was added before FDP pretreatment. CONCLUSIONS: Pretreatment with FDP significantly ameliorates acute lung injury induced by ischemia-reperfusion in rats.
