Pressure-flow autoregulation, although weak, was seen in the hepatic artery (HA) of every cat that also showed dilation to infused adenosine. Several means of quantitating autoregulation are described and evaluated, and all indices showed that the selective adenosine antagonists, 8-phenyltheophylline

Morphine was injected into the periaqueductal gray region of the rat and 8-phenyltheophylline, an adenosine receptor antagonist, was injected intrathecally 15 or 30 min later, to determine whether supraspinally-administered morphine activated descending mechanisms to release adenosine (or a nucleotide which

Chronic musculoskeletal pain involves connective tissue remodeling triggered by inflammatory mediators, such as bradykinin. Fibroblast cells signaling involve changes in intracellular Ca2+ ([Ca2+]i). ATP has been related to connective tissue mechanotransduction, remodeling and chronic inflammatory pain, via P2 purinoceptors activation.
