1958年大跃进中,发现福建产的美舌藻(属红藻类),在动物身上有显著降低血压的作用。曾分别用大白鼠尾间接测压法,测验(不麻醉的)大白鼠在灌药前后的血压变化情况,证明美舌藻煎剂,具有明显的降低血压的效果,并且作用时间能维持1小时以上。用麻醉猫(乌拉坦)作实验,自股静脈给药后,血压降低到比原来水平差30—90毫米汞柱,剂量大小与降压程度成正此,经历30—120分钟才恢复。对于麻醉的家兔,无论灌胃或静脈注射,亦均可出现降压效果。曾以慢性肾型高血压的狗服美舌藻煎剂(浓缩的药液混于肉食中),观 During the Great Leap Forward in 1958, it was discovered that the fusiliformis (red algae) produced in Fujian had a significant blood pressure lowering effect in animals. Previously, indirect manometry was used to measure the blood pressure changes in rats before and after administration, demonstrating that the United States can have a significant effect in lowering blood pressure, and the duration of action can be maintained for 1 hour. the above. With anesthetized cats (Urantan) as an experiment, blood pressure was reduced to 30-90 mm Hg lower than the original level after administration from the femoral vein, and the dose size and the degree of decompression became the same, and it took 30-120 minutes to recover. For anesthetized rabbits, antihypertensive effects can also occur regardless of whether they are administered or injected intravenously. Dogs who used to have chronic kidney-type hypertension served as a beautiful tongue algae decoction (the concentrated liquid was mixed with meat).
