Gastrointestinal Contrast Agents
JAMA, 1983THE TWO major categories of contrast agents currently used to opacify the lumen of the gastrointestinal (GI) tract are barium sulfate suspensions and the iodinated water-soluble materials. Despite an extensive experience with these contrast media in the GI tract, confusion remains over their proper utilization.

Effects of Pharmacological Agents on Gastrointestinal Motility
Veterinary Clinics of North America: Equine Practice, 1989The control mechanisms of gastrointestinal motility are complex. Extrinsic neurohormonal effects modulate an intrinsic system, often called the "gut brain," composed of nervous and neuropeptide components. To exert pharmacologic influence on GI motility, use is made of agents that mimic the external control system.

Serotonergic agents in the treatment of functional gastrointestinal disorders
Current Treatment Options in Gastroenterology, 2002Functional gastrointestinal disorders are exceptionally common, cause a great deal of suffering, and are extremely challenging to treat. Current therapies, usually targeted at possible abnormalities of gut contractility, are often disappointing and there is a real need for a new approach to treatment. Over the last decade, there has been an increase in

[Antiangiogenic agents and gastrointestinal cancers].
Gastroenterologie clinique et biologique, 2008The role of angiogenesis in tumor development and the identification of VEGF as a key factor in this process have recently led to the development of anti-angiogenic agents in the treatment of cancer. Among them, the major are those targeting the VEGF pathway, including anti-VEGF antibodies (bevacizumab) and VEGF receptor tyrosine kinase inhibitors ...
