RESUMEN
AIM: Effect of ischemia/reperfusion on expression of endothelin-1(ET-1) in the rat prostate and preventive measure were studied. METHODS: The abdominal aorta of rat was clipped briefly and repeatedly so as to treat the prostate with ischemia/reperfusion and expression of ET-1 mRNA in the ventral prostate was determined by RT-PCR.RESULTS: Expression of ET-1 mRNA in the ventral prostate was significantly increased at 1 h and 3 h after 90 min repeated ischemia/reperfusion ( P 0 05). CONCLUSIONS: Expression of ET-1 in the prostate can be affected by repeated brief ischemia/reperfusion and it may play a role in the development of benign prostatic hyperplasia. Ischemia-reperfusion-induced ET-1 expression in the prostate of rats can be inhibited by prectreatment of MK-801.
