ABSTRACT
<p><b>OBJECTIVE</b>To observe the changes and characteristics of interdigestive migrating motor complex (MMC) in rat models of acute liver failure.</p><p><b>METHODS</b>30 rat models with acute liver failure were induced with D-galactosamine and another 30 normal rats were used as controls. The indexes of MMC recorded by multi-channel physiological recorder were compared.</p><p><b>RESULTS</b>No significant differences found between the two groups in antral and duodenal MMC cycles and frequencies of duodenal and jejunal MMC III phase. Compared with normal controls, the MMC II phase in the acute liver failure rats was significantly prolonged (t=-3.97, -3.85, P<0.05), the MMC III duration of antrum and duodenum (u=-4.99, t=4.66, P<0.05) was shorter and the MMC III frequency of antrum (u=-4.73, P<0.05) was faster. In addition, the MMC cycle and MMC III phase of jejunum were significantly prolonged (u=-1.63, t=-4.94, P<0.05) and the MMC III phase duration was significantly shorter in the acute liver failure rats (t=5.10, P<0.05).</p><p><b>CONCLUSION</b>Significantly prolonged MMC II phase characterized by migrating clustered contraction, shortened MMC III phase and extended jejunal MMC cycles were probably the major contributors to the gastrointestinal motility disorders in the rats with acute liver failure.</p>
