Abstract/OtherAbstract:
We had previously studied different modes of prevention of liver ischemia-reperfusion (IR)-induced remote organ reperfusion injury, a challenge that remains partly unmet. We have now studied the capability of mannitol at different doses in abrogating liver IR-induced lung reperfusion injury in an isolated double-organ model. Rat livers ( n = 8/group) were perfused with Krebs-Henseleit solution (control) or made globally ischemic (IR) for 2 h, after which they were paired with normal lungs and "reperfused" together for 15 min. The lungs were then perfused alone with the accumulated Krebs for an additional 45 min. Another 4 control and 4 IR pairs were reperfused with Krebs containing mannitol at.22 mmol,.55 mmol,.77 mmol, or 1.1 mmol. Mannitol.22 mmol and 1.1 mmol failed to attenuate IR-lung injury as indicated by 50-95% increases in inspiratory and perfusion pressures and compliance reduction, a 70% increase in weight gain, and a 2-50-fold increase in bronchoalveolar lavage volume and content. Mannitol.55 mmol prevented all these abnormalities, and.77 mmol attenuated only changes in ventilatory parameters. The latter two treatments were also associated with a 50% reduction in xanthine oxidase activity and a 35-45% increase in the reduced glutathione tissue content compared with the nontreated IR-paired lungs. It is concluded that mannitol in a narrow therapeutic dose range can reduce oxidalive stress-induced lung damage that is related to liver IR.
