We recorded human jejunal motor activity by a 12-lumen manometric tube with recording sites 2 cm apart. The contractile activity in the fasted and the fed state was analyzed by computer to define the spatial and temporal patterns of contractions. Mean duration and area of single contractions during phase III activity were not different from those during(More)
Previous work using human jejunal brush-border membrane vesicles has demonstrated the existence of a distinct transport system in man for acidic amino acids. This system is energized by an inwardly directed Na+ gradient and an outwardly directed K+ gradient. These studies further characterize the transport of L-glutamate in the human jejunal brush-border(More)
