The histological characteristics and localisation of ACP and ANAE positive lymphocytes in the oesophageal tonsil of the duck (Anas platyrhynchos)

Hasan Hüseyin DÖNMEZ

This study was carried out to examine histological and enzyme histochemical characteristics of the oesophageal tonsil in ducks (Anas platyrhynchos). Tissue samples were collected from distal parts of the mucosal folds at the oesophageal y proventricular junction. We applied alpha naphthyl acetate esterase and acid phosphatase to tissue sections for localisation of T or B lymphocytes. Trichrome staining, silver impregnation, methyl green-pyronin staining and PAS reaction were used for determination of light microscopic structure of the oesophageal tonsils. The oesophageal tonsils were located a ...Более
