4.静脉注射的影响将0.2——0.5mg/kg 氯化钪(以 Se 计)注射于猫静脉内,对各个系统均产生抑制作用,并可导致呼吸停止和血管萎陷而死亡。静脉注射10～20mg/kg 氯化铕(以Eu 计)可引起猫和狗的血压瞬时降低;23—76mg/kg 则引起大鼠心电图的明显变化,尤其是事先用苯巴比妥钠进行麻醉,变化更加显著(Zanni et at.,1965)。对小白鼠 4. Effects of Intravenous Infusion 0.2--0.5 mg / kg scandium chloride (calculated as Se) is injected into the veins of cats and has an inhibitory effect on all systems and can result in cessation of respiration and vascular collapse. Intravenous injection of 10-20 mg / kg europium chloride (Eu) caused transient decreases in blood pressure in cats and dogs; 23-76 mg / kg caused significant changes in the electrocardiogram of the rats, especially with prior anesthesia with phenobarbital sodium , The change is even more significant (Zanni et at., 1965).
