Abstract:
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), and was not significantly changed after previous treatment of Dizocilpine maleate (MK-801) (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.
