the exposure of isolated strips of rabbit urinary bladder to a glucose deficient medium equilibrated with nitrogen rather than with oxygen resulted in 1 ) a rapid decrease in baseline tension , 2 ) a progressive decrease in the intracellular concentration of adenosine 5'-triphosphate ( atp ) and progressive increases in the concentrations of adenosine 5'-monophosphate and adenosine 5'-diphosphate , 3 ) a rapid decrease in the ability of bethanechol to stimulate contractility , and 4 ) the inability of bethanechol to maintain a sustained increase in contractile force .
