黄耆在神农本草经列为上品,属豆科植物,药用其根部。黄耆的药理作用曾有过一些报导。鉴于有关其降压作用的报导采用粗制剂由静脉给药,而新近灌胃给药也能降压的报导只是两只麻醉犬的结果。考虑到中医传统均系口服给药,而一个药物经由静脉给药对血压的影响可以与口服给药完全不同,因此,本实验主要观察了黄耆煎剂灌胃给药对正常动物血压的影响,同时也观察了该药在降压时对血管的作用。此外,还观察了口服黄耆的利尿作用,将另文发表。
Astragalus membranaceus is classified as a top grade in Shennongbong, which is a leguminous plant and its root is used medicinally. There have been several reports of the pharmacological effects of Astragalus. In view of reports on its antihypertensive effect, the use of crude preparations for intravenous administration and recent intragastric administration for antihypertensive reports are the result of only two anesthetic dogs. Considering that all traditional Chinese medicines are administered orally, the effect of one drug via intravenous administration on blood pressure may be completely different from oral administration. Therefore, this experiment mainly observed the effect of intragastric administration of Huangqi decoction on blood pressure in normal animals. At the same time, the effect of the drug on blood vessels during blood pressure reduction was also observed. In addition, the diuretic effect of oral jaundice was also observed and will be published separately.
