Abstract
1. alpha- and beta-Adrenergic agonists as well as insulin stimulate 3-O-methyl-D-glucose efflux by the perfused rat heart and increase D-glucose inhibitable cytochalasin B binding by isolated sarcolemma. 2. alpha- and beta-Agonists like insulin increase Vmax for 3-O-methyl-D-glucose efflux and increase Bmax for cytochalasin B binding. 3. The effects of alpha- and beta-agonists are totally Ca2+-dependent whilst those of insulin appear to be only partly Ca2+-dependent.
肾上腺素能激动剂与胰岛素对灌注大鼠心脏3- o -甲基- d -葡萄糖外排及肌层细胞松弛素B结合影响的比较。
1. -和-肾上腺素能激动剂以及胰岛素刺激灌注大鼠心脏的3- o -甲基- d -葡萄糖外排,并增加d -葡萄糖抑制细胞松弛素B与分离的肌膜的结合。2. -和-激动剂如胰岛素增加3- o -甲基- d -葡萄糖外排的Vmax和增加细胞松弛素B结合的Bmax。3.α和β激动剂的作用完全依赖于Ca2+,而胰岛素的作用似乎只是部分依赖于Ca2+。
