[Electromyographic and manometric studies of the antrum and duodenal motility in rabbits under the influence of pentagastrin in a mechanical duodenal passage disorder].

The influence of a mechanical disturbance of the duodenum on the motility of the antrum and duodenum was investigated by means of the electromyography and the perfusion manometry. Thereby the effect of the pentagastrin stimulating the motility of the unstriated muscles of the gastro-intestinal tract was used for testing the function reserve of the antrum- and duodenal-muscles. After one and a half month of establishing the passage obstacle there occurs a complex disturbance of the electrical activity; the unstriated muscles does not react on a stimulating excitation.
