AIM: To investigate the effects of a novel Leukotriene B4 receptor antagonist and/or tacrolimus on ischemia-reperfusion in a rat liver model. METHODS: Male Lewis rats were pretreated with ONO-4057 (100 mg/kg) and/or tacrolimus (1 mg/kg) orally, and divided into four experimental groups; group 1 (control), group 2 (ONO-4057), group 3 (tacrolimus), group 4 (ONO-4057 + tacrolimus). RESULTS: There was a tendency for long survival in the groups treated with tacrolimus alone and ONO-4057 plus tacrolimus. Post-reperfusion serum aspartate aminotransferase levels decreased more signif icantly in ONO-4057 plus tacrolimus group (P < 0.01), than in the tacrolimus alone group (P < 0.05), compared to controls. CONCLUSION: This study demonstrated that pretreat-ment with ONO-4057 in combination with tacrolimus produced additive effects in a rat model of liver isch-emia-reperfusion injury.
