The mechanism of this anomalous vascular response is unknown . 此种不规则的血管反应的机制尚不清楚。
Effects of tetrandrine on phenotypic modulation of vascular smooth muscle cells and expression of p38 after intimal injury 粉防己碱对肾血管性高血压大鼠阻力血管反应性的影响
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 ] 。
