Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...

The features of cholesterol crystal embolisation (CCE) to the alimentary tract were studied by retrospective analysis of the clinical and pathological data of 96 patients (70 men, 26 women, mean age 73.8 (58-95) years) with this diagnosis in the Dutch national pathology information system (Pathologisch Anatomisch Landelijk Geautomatiseerd Archief (PALGA)) from 1973-92. In the 96 patients, 130 C...

Duplication cysts (DCs) of alimentary tract are rare congenital malformations. They are firmly attached to the wall of the gastrointestinal tract and they are supplied by surrounding mesenteric blood vessels. More than 80% of cases occur before the age of two years and only a minority of cases present in adulthood. "Completely isolated duplication" of the alimentary tract is an extremely rare v...

The clinical and pathological findings in 23 patients with ischaemic lesions of the alimentary tract (ischaemic enterocolitis) are described. These are compared with findings in 13 patients with occlusive thrombosis of the superior mesenteric artery. The pathological features distinguishing the two conditions are discussed. Ischaemic enterocolitis was found to be a relatively common condition (...

Acetylcholine is a transmitter in preganglionic autonomic and postganglionic parasympathetic nerves and a non-neuronal paracrine mediator in the alimentary tract. Acetylcholine is involved in the control of almost any function within these organ systems, and almost every cell type expresses multiple muscarinic receptor subtypes. Although muscarinic receptors at non-neuronal effector cells commo...

Cancer involving the alimentary tract may produce signifi cant effects on the nutritional status of the patient. The organs in the gastrointestinal system are among the most metabolically active in the body. Consequently, food depni Vation may adversely affect absorptive capacity and contrib ute to malabsorption by its effect on intestinal mucosal enzymes. Mucosal changes associated with malnut...
