Contractile actions of L-type Ca2+ agonists in human vas deferens and effects of structurally different ca2+ antagonists

The actions of L-type Ca(2+) agonists, FPL 64176 and Bay K 8644 were investigated in human vas deferens in the presence of structurally different L-type Ca(2+) antagonists. The L-type Ca(2+) agonists (or=20 min) evoked only rhythmic contractility even in moderately depolarizing ([K(+)](o), 10mM) med...
