用放射性核素１４１Ｃｅ作示踪剂，通过对稀土Ｃｅ３＋在大鼠主动脉上的跨膜内流的研究表明，去甲肾上腺素（１．２μｍｏｌ／Ｌ）和ＫＣｌ（１００ｍｏｌ／Ｌ）都可引起Ｃｅ３＋跨膜内流量的增加，并以ＫＣｌ（１００ｍｏｌ／Ｌ）引起的增加量较多．钙拮抗剂Ｖｅｒａｐａｍｉｌ（１μｍｏｌ／Ｌ）对去甲肾上腺素（１．２μｍｏｌ／Ｌ）和ＫＣｌ（１００ｍｏｌ／Ｌ）引起的Ｃｅ３＋跨膜内流无明显的阻滞作用．
Using radionuclide 141Ce as a tracer, studies on the transmembrane influx of rare earth Ce3 + in rat aorta showed that both norepinephrine (1.2 μmol / L) and KCl (100 mol / L) The increase of Ce3 + transmembrane flux increased more with KCl (100mol / L). The effect of Verapamil (1μmol / L) on the Ce3 + transmembrane influx induced by norepinephrine (1.2μmol / L) and KCl (100mol / L) was not obvious.
