2. Fig. 1
Time course of serum amylase activity after administration of adenosine-receptor agonists. Rats were injected IP with 1 mL saline (■), 3 mg/kg CCPA (○), 3 mg/kg CGS (●), or 0.75 mg/kg IB-MECA (□). Each result was obtained in 10 rats; data are means ± SEM. Vertical bars denote SEM; absence of such bars indicates that the SEM is too small to illustrate. *P < 0.05, **P < 0.01; significant difference compared with saline-treated group.

3. Fig. 2
Effects of adenosine-receptor agonists on pancreatic tissue edema. Rats were injected IP with saline (□, control), 3 mg/kg CCPA (■), 3 mg/kg CGS (▩), or 0.75 mg/kg IB-MECA (▨). Pancreatic edema was evaluated as described in Materials and Methods. Each result was obtained in 8 rats; data are means ± SEM. *P < 0.05, **P < 0.01; significant difference compared with saline-treated group.

Light-microscopic photographs of the pancreas. (A) Pancreas from normal rat. (B) Pancreas 24 hours after administration of 3 mg/kg CCPA (original magnification 50×). Remarkable interstitial edema, hemorrhage, and inflammatory cell infiltration to the interstitium can be seen. A few vacuoles are seen in acinar cells.

5. Fig. 4
Effects of CCPA or CCPA plus FK-838 on the pancreatic blood flow. Rats were injected IP with saline (□, control), 3 mg/kg CCPA (■), or 3 mg/kg CCPA plus 10 mg/kg FK-838 (▩). FK-838 was given IP 30 minutes before CCPA. Each result was obtained in 10 rats; data are means ± SEM. **P < 0.01; significant difference compared with saline-treated group.
