20年前,艾弗森(1965 A)发现,在大鼠心脏中,去甲肾上腺素不仅是众所周知的神经元摄取(Uptake1)的底物,而且是第二种摄取机制(Uptake2)的底物,这显然不同于uptak1。这种新的摄取机制最初被认为与肾上腺素能神经末梢有关(Iversen 1965 A),但荧光显微镜很快显示Up-2导致去甲肾上腺素在心肌细胞中积累(Malmfors 1967;Ehinger和Sporrong 1968;Farnebo 1968);放射自显影后来证实心肌细胞是异丙肾上腺素通过大鼠心脏灌流的主要分布空间(Azevedo等人)。1983年)。
Twenty years ago Iversen (1965 a) discovered that, in the rat heart, noradrenaline is a substrate not only of the well-known neuronal uptake (uptake1) but also of a second uptake mechanism (uptake2) which clearly differed from uptake1. The new uptake mechanism was first believed to be associated with adrenergic nerve endings (Iversen 1965 a), but fluorescence microscopy soon revealed that uptake2 resulted in the accumulation of noradrenaline in myocardial cells (Malmfors 1967; Ehinger and Sporrong 1968; Farnebo 1968); autoradiography later confirmed that myocardial cells are the main distribution compartment for isoprenaline perfused through the rat heart (Azevedo et al. 1983).
