We investigated whether a single dose of standardized Ginkgo biloba extract (GBE) can improve vascular function. A randomised controlled crossover trial was conducted on 14 young healthy men, who received GBE or placebo. The digital volume pulse was monitored to measure reflection index (DVP-RI) and stiffness index (DVP-SI) and peripheral augmentation index (pAIx) was assessed using radial pulse wave analysis at baseline and 2, 4 and 6 h after treatment. DVP-SI was slightly higher 2 h following GBE compared to placebo (P < 0.05); other outcome variables were unaffected by treatment.
我们研究了单次剂量标准化银杏叶提取物（GBE）是否可以改善血管功能。在 14 名年轻健康男性中进行了一项随机对照交叉试验，他们分别接受 GBE 或安慰剂治疗。通过监测数字体积脉搏来测量反射指数（DVP-RI）和硬度指数（DVP-SI），并使用桡动脉脉搏波分析在治疗后 2、4 和 6 小时评估外周增强指数（pAIx）。与安慰剂相比，GBE 治疗后 2 小时 DVP-SI 略有升高（P<0.05）；其他结果变量不受治疗影响。
