Comparison of different methods of intestinal obstruction in a rat model

Figure 6 Change in pacemaker activity in the ileum. Typical intracellular electrical activity (slow waves) recorded in the small intestine of control rats and at 12-72 h at the site of intestinal obstruction. A: Control; B: Braided silk; C: Half ligation; D: Wide pipe; E: Narrow pipe; F: Data on slow wave frequency in normal functioning tissue away from the obstruction site; G: Slow-wave amplitude was markedly reduced near the site of obstruction and increased in amplitude in normal functioning tissue away from the obstruction site.
