title: [Characteristics of periodic motility of the upper portion of the jejunum in rabbits].
abstract: Proximal jejunal motility was studied balloonographically in rabbits devoid of food and in properly fed animals. Three phases of jejunal motor activity were revealed: the resting phase, irregular contraction phase and rhythmic phase. It was found that the regularity of rhythmic phase onset was not stable. The rate of continuous contractions during rhythmic phase and the rate of interrupted contractions during irregular phase coincided and were relatively constant. The feeding did not affect the rate of contractions during rhythmic and irregular phases, but increased the duration of the rhythmic phase.
