摘要
目的临床验证银杏叶提取物(ginkgo biolba extract,EGB)对急性脑梗死患者血小板磷酸二酯酶3(phos-phodiesterase3,PDE3)活性及其相关因素的影响,观察其临床疗效。方法 30例急性脑梗死患者为对照组,接受常规治疗。15例急性脑梗死患者,常规治疗外给予EGB治疗。分别于用药前、用药后第1、3、7、14天测定两组患者血小板PDE3活性、环腺苷酸(cylic adenosine monophosphate,cAMP)水平、胞浆游离钙离子([Ca2+]i)水平,并于用药前及用药后第14天进行神经功能缺损评分、血液流变学检查,作为临床疗效评价指标。结果 EGB可使急性脑梗死患者血小板PDE3活性进一步下降,大大提升cAMP水平,降低胞浆[Ca2+]i浓度,改善血液流变学及神经功能缺损情况。结论 EGB可使急性脑梗死患者血小板PDE3活性进一步下降,加强PDE3在脑梗死急性期的保护作用,有效抑制血小板聚集,改善血液循环及神经功能缺损。
