Histological and histochemical characterization of the mucosa of the digestive tract in flower fish (Pseudophoxinus antalyae)

Anat Histol Embryol. 2006 Jun;35(3):147-51. doi: 10.1111/j.1439-0264.2005.00629.x.


The wall of the digestive tract is composed of the tunica mucosa, tunica muscularis and tunica serosa. Lamina-submucosa separation or any glands were not observed in tunica mucosa. Goblet cells were determined to constitute a much larger reserve at digestive tract mucosa. Histochemical analysis of the intestine of flower fish (Pseudophoxinus antalyae) showed that gastrointestinal mucous content included sulphate-esters and/or carboxylic [Alcian blue (AB) 0.06+], glycogene and/or oxidable dioles [periodic acid/Schiff+ (PAS+)], neutral or acid-rich (PAS/AB pH 2.5+), sialic acid residues (KOH/PAS) and strong acid sulphated [Aldehyde fuchsin+ (AF+)] glycoproteins (GPs). Except these mucosubstances to lower densities, densely sulphate (AB pH 2.5+), O-sulphate esters (AB pH 1+) strong and weak sulphated (AB 0.3 M+), GPs were also determined.
