- This effect has been hypothesized to occur through an initial reduction in sympathetic outflow from the central nervous system with its associated decrease in vascular resistance , followed by a peripheral vascular receptor mediated increase in vasoconstriction ( 1 , 4 )
该作用被假设发生，通过对来自于中枢神经系统的交感系统的最初抑制，伴有相关的血管阻力的降低，并伴随着外周血管受体介导的血管收缩的增加[ 1 ， 4 ] 。 - Ephedrine and phenylephrine can treat the hypotension , howeer an amplified asoconstrictie response may be obsered due to an alpha 2 agonist induced enhancement of baroreceptor reflexes ( 7 ) and potentiation of alpha 1 - adrenoceptor - mediated asoconstriction
麻黄素和苯肾上腺素可治疗低血压，然而可以观察到存在过度缩血管反应，因为- 2受体激动剂导致压力感受器反射[ 7 ]和- 1肾上腺素受体介导的血管收缩作用增强[ 8 ] 。 - Within six hours after an infant is placed in a high - oxygen atmosphere , vasoconstriction of the immature vessels of the retina occurs , which is reversible if the child is immediately returned to air , but irreversible if oxygen - rich therapy is continued
婴儿置于含氧浓度高的空气中6个小时以内，未发育成熟的视网膜血管会发生血管收缩，如果立刻把孩子转移到空气中，这是可逆的，如果富氧治疗继续的话，会变成不可逆的。 - Ephedrine and phenylephrine can treat the hypotension , however an amplified vasoconstrictive response may be observed due to an alpha 2 agonist induced enhancement of baroreceptor reflexes ( 7 ) and potentiation of alpha 1 - adrenoceptor - mediated vasoconstriction
麻黄素和苯肾上腺素可治疗低血压，然而可以观察到存在过度缩血管反应，因为- 2受体激动剂导致压力感受器反射[ 7 ]和- 1肾上腺素受体介导的血管收缩作用增强[ 8 ] 。 - Wt5hzresults lnmma injection alone can inhibit the na induced vasomotion in vasoconstriction state , while si injection alone can inhibit it in vasodilation state . si could abolish the effect of lnmma on vasomotion but lnmma did not influence the effect of si on vasomotion
在lnmma的有效作用时间内应用si可使被抑制于收缩状态的血管重新扩张，血管运动得以恢复在si的有效作用时间内应用lnmma则不能使处于舒张状态的血管收缩。
百科释义
血管收缩，亦即血管收窄，是指体内血管管腔收窄，这会造成血压的上升。它的相反过程称为血管舒张。
