  摘要：

  以下是中文翻译： 评估了来自内皮的NO、前列环素和内皮源性超极化因子（EDHF）在介导乙酰胆碱和缓激肽引发的血管舒张反应中的作用，实验对象为牛孤立灌注眼的睫状血管床。 乙酰胆碱或缓激肽引起的血管舒张不受NO合成酶抑制剂（L-NAME，100 μM）或环氧化酶抑制剂（flurbiprofen，30 μM）的影响，但在给予高浓度KCl（30 mM）或使用洗涤剂CHAPS（0.3%，2 min）破坏内皮后，血管舒张几乎完全消失。 乙酰胆碱诱导的血管舒张不受ATP敏感型K+通道抑制剂（glibenclamide，10 μM）的影响，但在给予非选择性K+通道抑制剂（TEA，10 mM）后显著减弱。 小导电钙敏感型K+通道（SK+Ca）抑制剂（apamin，100 nM）和大导电钙敏感型K+通道（BK+Ca）抑制剂（iberiotoxin，50 nM）对乙酰胆碱诱导的血管舒张无显著影响。相比之下，中/大导电钙敏感型K+通道抑制剂（charybdotoxin，50 nM）强烈阻断了这些血管舒张反应，并揭示了血管收缩反应。 apamin（100 nM）与sub-threshold浓度的charybdotoxin（10 nM）组合显著减弱乙酰胆碱诱导的血管舒张，而apamin（100 nM）与iberiotoxin（50 nM）组合无影响。 综上所述，高浓度KCl、charybdotoxin或apamin与sub-threshold浓度charybdotoxin的组合对血管舒张的强烈阻断，强烈表明牛孤立灌注眼中的血管舒张是由EDHF介导的。 British Journal of Pharmacology (2001) 134, 912–920; doi:10.1038/sj.bjp.0704332
