Figure 1 Effects of OFQ (10-9-10-6mol/L) on colon of rats in vitro. A: Effects of OFQ on the contractile activity of longitudinal muscle strips obtained from the rat proximal colon; B: Different effects of OFQ (10-9-10-6 mol/L) on increment of tension in two groups of rats. aP < 0.05 vs 1 × 10-9 mol/L; bP < 0.01 vs 1 × 10-9 mol/L; C: In the presence of TTX (10-6 mol/L), OFQ (10-6 mol/L) failed to evoke additional contractions; D: The response to OFQ (1 × 10-6 mol/L) was not affected by naloxone (1 × 10-6 mol/L).
