we demonstrated transient reversal of constriction in this arterial model during coinfusion with endothelin-1 ( 100 pmol/min ) of dihydropyridine calcium channel blocking agent nicardipine ( 0.5-20 nmol/min ) , substance p ( 0.5-50 fmol/min ) , adenosine ( 10-10,000 pmol/min ) , and isosorbide dinitrate ( 0.001-0.1 mg/min ) .
