pubmed-article:1878748 | pubmed:abstractText | 1. This study was carried out in order to identify the receptor responsible for adenosine-induced dilatation of the hepatic arterial vascular bed. 2. Livers of 10 New Zealand White rabbits were perfused in vitro with Krebs-Bülbring buffer via the hepatic artery and the portal vein at constant flows of 26 and 77 ml min-1 100 g-1 liver respectively. The tone of the preparation was raised by the presence of noradrenaline in the perfusate (concentration: 10(-5) M). 3. Dose-response curves for adenosine and its analogues 5'-N-ethyl-carboxamido-adenosine (NECA), the 2-substituted NECA analogue CGS 21680C, and R- and S-N6-phenyl-isopropyl-adenosine (R- and S-PIA) were obtained after their injection into the hepatic arterial supply. 4. The order of vasodilator potency of these agents was: NECA greater than CGS 21680C greater than adenosine greater than R-PIA greater than S-PIA. Their potency, expressed relative to that of adenosine, was in the approximate ratio 10:3:1:0.3:0.1, consistent with that resulting from activation of P1-purinoceptors of the A2 sub-type (which mediate vasodilatation due to adenosine). 5. The P1-purinoceptor antagonist 8-phenyltheophylline (10(-5) M) caused significant attenuation of the vasodilatation to adenosine and analogues. 6. It is concluded that adenosine-induced dilatation of the hepatic arterial vascular bed is mediated by P1-purinoceptors of the A2 sub-type. | lld:pubmed |
