1 strips of longitudinal muscle from rabbit intestine accumulated radioactivity when exposed to [ ( 3 ) h ] -adenosine.2 accumulation of radioactivity was not sodium-dependent or ouabain-sensitive , but was reduced by cooling , zero glucose plus bubbling with n ( 2 ) , 2,4 , dinitrophenol , dipyridamole , hexobendine and lidoflazine.3 after 7 min exposure to [ ( 3 ) h ] -adenosine , the tissue was found to contain radioactive adenosine triphosphate ( atp ) , adenosine diphosphate ( adp ) , adenosine monophosphate ( amp ) and adenosine itself in the approximate ratio 13 : 6 : 4 : 1.4 in the presence of dipyridamole , hexobendine or lidoflazine ( each 1 mum ) , the amounts of radioactive atp , adp , amp and adenosine were reduced with the concentration of adenosine not significantly different from controls.5 it is concluded that energy-dependent uptake of adenosine does not occur in the longitudinal muscle of rabbit intestine .
