雌激素被认为在调节血管对内源性反应物质的反应中起重要作用。研究了17ß-雌二醇慢性体内治疗对青春期前雌性大鼠主动脉乙酰胆碱松弛反应的影响。17ß-雌二醇对乙酰胆碱诱导的舒张作用的选择性用另一种内皮依赖性舒张剂组胺对大鼠主动脉进行评价。17ß-雌二醇显著增强乙酰胆碱诱导的内皮依赖性松弛,但未改变从青春期前雌性大鼠分离的内皮剥离主动脉环中血管对乙酰胆碱的反应。相比之下,17ß-雌二醇未改变组胺诱导的内皮依赖性松弛。本研究结果表明,17ß-雌二醇选择性地增强了乙酰胆碱诱导的大鼠主动脉内皮依赖性松弛。
Estrogens have been postulated to play an important role in modulation of vascular responses to endogenous reactive substances. The effects of chronicin vivotreatment with 17ß-estradiol on relaxant responses to acetylcholine were investigated in the rat aorta isolated from prepubertal female rats. The selectivity of effects of 17ß-estradiol on acetylcholine-induced relaxation was evaluated using histamine, another endothelium-dependent relaxant in the rat aorta. 17ß-Estradiol significantly enhanced endothelium-dependent relaxation induced by acetylcholine, but did not alter the vascular responses to acetylcholine in endothelium-denuded aortic rings isolated from prepubertal female rats. In contrast, 17ß-estradiol did not change endothelium-dependent relaxation induced by histamine in endothelium-intact aortic rings. The results of the present study demostrate that 17ß-estradiol selectively enhanced acetylcholine-induced endothelium-dependent relaxation in the rat aorta.
