BackgroundThe structural elements of the vascular wall, namely, extracellular matrix and smooth muscle cells (SMCs), contribute to the overall stiffness of the vessel. In this study, we examined the crosslinking‐dependent and crosslinking‐indepen

1 The chronotropic effects of alpha- and beta-adrenoceptor agonists were investigated in the pithed rat. 2 The beta-adrenoceptor agonist, isoprenaline, produced only a positive chronotropic response. alpha 1-Adrenoceptor agonists, phenylephrine and a

In pithed rats or rabbits the pressor effects of catecholamines or sympathetic nerve stimulation can be reduced by "selective" antagonists of alpha 1- (prazosin) or alpha 2 (rauwolscine) adrenoceptors. In rabbits the pressor response to low and high

1. The pressor responses in the pithed rat to α-adrenoceptor agonists can be modified by alterations in arterial blood gas levels or by drugs which interfere with excitation-contraction coupling processes in the vascular smooth muscle, e.g. Ca2+-ent

1. By the sequential administration of α1- and α2-blockers it can be shown, in the pithed rabbit, that the dose/pressor response curve to noradrenaline consists of two separate curves, one for each receptor. α2-mediated responses predominate at lo

In the pithed rat, amidephrine a "selective" alpha 1-adrenoceptor agonist, evokes a positive chronotropic response. This response can be antagonized by prazosin but not by propranolol or by rauwolscine. Similarly, part of the chronotropic response to

In the pithed rat, following beta-adrenoceptor blockade, the pressor effect of adrenaline can be blocked by phentolamine or by prazosin plus yohimbine but not by prazosin or yohimbine given alone. It is concluded that adrenaline produces its pressor

The subtypes of alpha-adrenoceptors which mediate pressor responses to sympathomimetic agonists or to nerve stimulation in pithed rabbits have been classified according to the effects of 'selective' antagonists and a comparison has been made, for the
