Uncoupling of afferent and myoelectric reactions in portions of gastroduodenal complex in acute damage period

In two series of experiments on cats, afferent reactions of organs of the gastroduodenal complex (gastric corpus, pylorus, and duodenal bulb) were studied and myoelectric activity of these portions of the gastroduodenal complex was examined. In each series, only one portion of the gastroduodenal complex was stimulated with electrical pulses. It was found that processes underlying changes in functional heterogeneity and enhancement or moderation of their interrelations in the acute damage period can affect the development of early regional adaptation. © 2005 Springer Science+Business Media, Inc.
