Histochemical Structure of Stomach (Proventriculus and Gizzard) in Some Bird Species

Abstract

Stomach samples (proventriculus and gizzard) of sparrow hawk (Accipiter nisus), crow (Corvus corone) and sparrow (Passer domesticus) were investigated in this study. In histochemical investigations, strong sulfated mucins were not determined in compound glands of proventriculus, but a little reaction to AB (pH 0.5) in compound glands was observed in proventriculus of sparrow hawk and crow. While weak AB (pH 1.0) (+) character was found in sparrow gizzard, it was found as dense in superficial glands of sparrow hawk. However, it was not observed in crow gizzard. While AF (+) character (sulfated mucins) was detected as dense in epithelium and as weak in glands of gizzard of sparrow hawk, this character was not observed in glands of gizzards of crow and sparrow. Any reactivity to Periodic Acid-Shiff (PAS) staining was not observed in both epithelium and glands of sparrow proventriculus

Bazı Kuş Türlerinde Mide (Proventrikulus ve Gizzard)’nin Histokimyasal Yapısı

Abstract

Bu çalışmada atmaca (Accipiter nisus), karga (Corvus corone) ve serçeden (Passer domesticus) alınan mide örnekleri (proventrikulus ve gizzard) incelendi. Histokimyasal incelemelerde, proventrikulusun bileşik bezlerinde güçlü sülfatlı musinlere rastlanmadı; fakat atmaca ve karga proventrikulusunda bileşik bezlerde AB (pH 0.5)’e karşı zayıf bir reaksiyon gözlendi. Serçe gizzardında zayıf AB (pH 1.0) (+) karakter bulunurken, atmacanın superficial bezlerinde yoğundu. Bununla birlikte karga gizzardında bu karaktere rastlanmadı. AF(+) karakterin (sülfatlı
musinler) atmaca gizzardının epitelinde yoğun, bezlerinde zayıf olduğu tespit edilirken; karga ve serçe gizzardlarının bezlerinde bu karakter gözlenmedi. Serçe proventrikulusunun hem epiteli hem de bezlerinde Periyodik Asit-Shiff (PAS) boyamasına karşı hiç bir reaksiyon gözlenmedi.
