给实验动物输注拟交感胺药可使其动脉血的 PH 下降。这点已用肾上腺素,异丙肾上腺素和去甲肾上腺素予以证明。这三种拟交感胺药产生酸血症的效能,曾用戊巴比妥麻醉的大白鼠静脉输注这三种拟交感胺药20分钟进行过对比实验,分别给以异丙肾上腺素0.5μg/kg/min肾上腺素2μg/kg/min 和去甲肾上腺素5μg/kg/min 时,可降低 PH0.07～0.11单位。输注肾 The administration of the sympathetic amine to experimental animals decreases the arterial blood pH. This has been used adrenaline, isoproterenol and norepinephrine to be proved. These three sympathomimetic drugs produce the potency of acidosis. Rats that had been anesthetized with pentobarbital were intravenously injected with the three sympathomimetic drugs for 20 minutes to conduct comparative experiments. The rats were given isoproterenol 0.5 μg / kg / min epinephrine 2μg / kg / min and norepinephrine 5μg / kg / min, can reduce the PH0.07 ~ 0.11 units. Infusion kidney
