在第一报告中,我们的主要结论是:(一)经动物实验,地龙酊确有降低血压的作用。其特点为逐渐和持续的而非急剧的降压作用。(二)根据实验的初步观察,其中所含降压成分,除赵、张、朱氏(1937)自广地龙中提出的次黄嘌呤(Hypoxanthine)外,似尚含其他有效物质。为了进一步了解其降压有效成分,我们开展了本文的实验。 In the first report, our main conclusions are: (1) After animal experiments, Earthworm has indeed reduced blood pressure. It is characterized by gradual and continuous rather than abrupt depressurization. (b) According to the preliminary observation of the experiment, the hypotensive component contained in it, except for Hypoxanthine proposed by Zhao, Zhang, Zhu (1937) from Guangdi Longzhong, seems to contain other effective substances. In order to further understand its effective antihypertensive ingredients, we carried out the experiments in this article.
