Ulcerative Colitis: Ultrastructure of Interstitial Cells in Myenteric Plexus
Ultrastructural Pathology, 2010Interstitial cells of Cajal (ICC) are key regulatory cells in the gut. In the colon of patients with severe ulcerative colitis (UC), myenteric ICC had myoid ultrastructural features and were in close contact with nerve terminals. In all patients as opposed to controls, some ICC profiles showed degenerative changes, such as lipid droplets and irregular ...

Noradrenergic innervation of serotoninergic neurons in the myenteric plexus
Journal of Comparative Neurology, 1987AbstractThe monoaminergic innervation of the guinea pig small intestine was investigated to determine if there is an anatomical basis for the hypothesis that serotoninergic and noradrenergic neurons physiologically interact in the enteric nervous system.

Regulatory Peptides, 1990
Isolated myenteric nerve varicosities prepared from the myenteric plexus of the guinea pig ileum were investigated as a suitable model system with which to study the release of several neuropeptide-like immunoreactivities (-LI). Basal release of substance P-LI, neurokinin A-LI, Leu-enkephalin-LI and Met-enkephalin-LI was determined, and clear ...

Phosphatase activity in the myenteric plexus.
Morphologie et embryologie, 1983Intense and very intense reactions were obtained for acid phosphatase, calcium activated ATP-ase (pH 9.4), magnesium activated ATP-ase (pH 7.2) and glucose-6-phosphatase in the cytoplasms of the myenteric plexus nerve cells of the small intestine of Macacus rhesus and rabbit.

GABAergic Neurons in the Myenteric Plexus
1992Some 20 years ago, Hobbiger [8] speculated on the basis of pharmacological studies that GABA, then recently discovered as a constituent of nervous tissue, might have a role in neurotransmission in the enteric nervous system of the vertebrate gut. Subsequent work, however, soon focussed on GABA in relation to the vertebrate central nervous system ...

Slow synaptic potentials in AH-type myenteric plexus neurons
Pflügers Archiv - European Journal of Physiology, 1981Two types of slow depolarization were recorded in AH-type guinea pig myenteric plexus neurons when the myenteric plexus-longitudinal muscle preparation was stimulated transmurally with external electrodes. One depolarization was associated with a fall and the other with a rise in membrane resistance, the latter type (slow EPSP) being encountered about ...

Diagnosis and Treatment of Aganglionosis of the Myenteric Plexus
Archives of Surgery, 1957One of the most important advances in pediatric surgery during the past 10 years has been the clarification of the etiology of congenital megacolon and the evolution of a satisfactory form of surgical treatment. Many newborn infants who formerly died of "volvulus of the sigmoid," or "locked bowels," have been saved, and hundreds of older children have ...

Argyrophilia in the developing human myenteric plexus.
British journal of biomedical science, 1997Silver staining is a useful means of demonstrating enteric neurons, and an absence of argyrophilic neurons has been proposed as a cause of functional intestinal obstruction in infants. No systematic data are available about the origin and development of argyrophilia, or of normal neuronal appearances.
