cDNA of human interleukin-8 was expressed in E. coli bacteria, and recombi-nant human interleukin-8 ( rhIL- 8 ) was produced. The latter was used for treatment of rat intestinal ischemia-reperfusion(I-R) injury, and it was found that rhIL-8 significantly improved the hypotensive state of the animals,and it also inhibited the elevation of plasma endothelin level , decreased the intestinal myeloperoxidase activity, and obviously prolonged the survival timeof the animals. Perfusion of isolated rat superior mesenteric artery with rhIL-8 markedly inhibited endothelin synthesis or (and) release induced by anoxia. The above results suggest that rhIL- 8 may be an effective preventive and therapeutic agent for I-R injury through its inhibition on leukocyte adhesion and endothelin synthesis or (and) release.
