摘要：

The mechanism of β-adrenergic relaxation was investigated in isolated smooth muscle cells. β-adrenergic agents stimulate cyclic AMP-dependent phosphorylation, enhance Na+/K+ transport and induce relaxation. The stimulation of Na+/K+ transport is obligatory for relaxation, and we suggest that this stimulation induces relaxation through enhanced Na+/Ca2+ exchange. © 1979 Nature Publishing Group.
