Alpha 2-adrenoceptors mediate norepinephrine constriction of porcine pial veins.


The adrenergic innervation and alpha-adrenoceptor agonist-induced constrictions in isolated medium-size pial veins (OD 734 +/- 18 microns) of the pig were investigated. Using in vitro tissue bath techniques, we noted exogenously applied norepinephrine (10(-9) to 10(-5) M) induced venoconstriction with EC50 values of 1.71 x 10(-7) M, where EC50 is the… (More)
