长期使用抗高血压药物对大鼠血管内皮依赖性松弛功能的影响

Effects of Long-term Antihypertensive Treatment on the Function of Endothelium- dependent Relaxation in Spontaneously Hypertensive Rats

选用7种抗高血压药,研究长期使用后对自发性高血压大鼠主动脉内皮依赖性松驰功能的影响。结果表明双氢克尿塞、安替洛尔和卡普托利可明显改善自发性高血压大鼠的主动脉内皮依赖性松驰功能,而哌唑嗪、尼群地平、粉防己碱和双肼苯达嗪则无此作用,同时亦发现内皮依赖性松驰功能的改善与血压下降的程度无相关性。

The effects of long-term treatments with 7 antihypertensive agents on the functions of endothelium-dependent relaxation were studied in spontaneously hypertensive rats (SHR). It was found that captopril, atenolol and dihydrochlorothiazide (DHT) could prevent the endothelium in SHR from impairing, but tetrandrine, nitrendipine, prazosin and dihydralazine could not. The improvement of the function of endothelium-dependent relaxation was not related to the blood pressure lowing.
