Fig. 5. Influence of an adenosine receptor antagonist and agonist on adenosine
action. COX activities were determined in isolated hepatocytes after 48 or 72
h of incubation and normalized to the mean of the control group. Cells were
treated with the adenosine receptor antagonist 8-PT combined with adenosine
(ado) or with the adenosine agonist NECA instead of adenosine and are compared
to their analogous control and adenosine-treated groups. All reagents were
supplied at a concentration of 100 nmol ml–1. Cells were
prepared from warm-acclimated Z. viviparus and incubated at 11°C.
*Significant difference from control. Values are means ±
s.e.m. (N=4–6).
