Actions of Probiotics on Trinitrobenzenesulfonic Acid-Induced Colitis in Rats

Figure 3

Effects of a NOS inhibitor on spontaneous contractions and electrical field stimulation- (EFS-) induced contractions in isolated colonic preparations from rats. Representative tracings of mechanical responses in the absence and presence of a NOS inhibitor, L-NAME (200 μM), in an intact rat (a), a TNBS-treated rat with the control diet at 14 days after TNBS treatment (b), and a TNBS-treated rat with the SF3B-containing diet at 14 days after TNBS treatment (c) are shown. Circles indicate the points of EFS.
