Figure 3. Increase in plasma concentration of norepinephrine (NE) after NCI.
(A) NCI did not alter expression of β2ARs in colon DRGs. (B) NCI markedly enhanced concentration of NE in blood plasma. *p < 0.05 vs. control (CON). (C) Application of NE (100 μg/1ml, i.p.) enhanced AWR scores in healthy rats. *p < 0.05 vs. baseline (Pre). (D) Time course of effect of NE at 100 μg/ml. Application of NE reduced distention threshold, starting at 0.5h and maintaining for at least 4h within our observation time period. *p < 0.05, compared with Pre.
