The Efficacy of Severe Whitening and Delayed Fading in Acetic Acid-enhanced Endoscopy for Diagnosing Gastric Intestinal Metaplasia

2016-06-20 18:53:21 | BioPortfolio


Investigators found that the degree and the duration of aceto-whitening differed between gastric intestinal metaplasia(GIM) and the surrounding normal mucosa: the area of GIM showed a severe degree of aceto whiteness and the whitening continued longer than the surrounding normal mucosa, which investigators called "severe whitening" and "delayed fading", and investigators realized that GIM could possibly be diagnosed by using these differences.The aim of this prospective study was to investigate the efficacy of "severe whitening" and "delayed fading" for diagnosing GIM.

Medical and Biotech [MESH] Definitions

ACETIC ACID or acetic acid esters substituted with one or more CHLORINE atoms.

Acetic acid and its derivatives which may be formed by substitution reactions. Mono- and di-substituted, as well as halogenated compounds have been synthesized.

A very strong halogenated derivative of acetic acid. It is used in acid catalyzed reactions, especially those where an ester is cleaved in peptide synthesis.

Derivatives of phenylacetic acid. Included under this heading are a variety of acid forms, salts, esters, and amides that contain the benzeneacetic acid structure. Note that this class of compounds should not be confused with derivatives of phenyl acetate, which contain the PHENOL ester of ACETIC ACID.

A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
