Figure 3. Effect of dihydralazine on muscular kinin liberation induced by adenosine.

Changes (expressed as percentage of the mean concentration of the three baseline samples) in the microdialysis concentration of kinin peptides (measured as bradykinin) after the perfusion with Ringer solution (control •, n= 5), or 50 and 100 μM adenosine in Ringer solution (adenosine ▿, n= 7) or in Ringer solution containing 125 mg l⁻¹ dihydralazine (adenosine + DHZ ▪, n= 5).
