Sudak (Stizostedion lucioperca L., 1758) Baliğinin Gastrointestinal Kanalinin Histokimyasal Yapisi

Ozet: Bu calismada sudak (Stizostedion lucioperca) baliginin mide ve bagirsak bolgelerinin histokimyasal yapisinin belirlenmesi amaclanmaktadir. Sudaklarin mide (kardiya, fundus, pilorus) ile ilk, orta ve son bagirsaklarindan doku ornekleri alinip, gastrointestinal mukosubstans ozelliklerinin belirlenmesi icin histokimyasal boyama yontemleri uygulandi. Uygulanan histokimyasal boyama yontemlerinin, sudak baliginin calisilan tum bolgelerinde reaksiyon verdigi saptandi. Asidik mukosubstansin mide bolgelerinde, notr ve sulfatli mukosubstansin ise bagirsaklarda fazla oldugu belirlendi. AB pH 1.0, AB pH 0.5, AB 0.06 M ve AB 0.3 M uygulamalarinda reaksiyonun oldukca zayif oldugu saptandi. Anahtar kelimeler: Histokimya, mukosubstans, sudak (Stizostedion lucioperca) Abstract: Purpose of this study was to determine the histochemical structure of zander (Stizostedion lucioperca) on stomach and intestines. Tissue samples were taken from stomach (cardiac, fundus, pylorus), anterior, middle and posterior intestine and performed histochemical staining methods for determination of gastrointestinal mucosubstance. The histochemical stain methods were found to react in all studied parts of zander. The acidic mucosubstance was too much in the stomach, while the neutral and sulphated mucosubstance were found to be too much in the intestine. AB pH 1.0, AB pH 0.5, AB 0.06 M and AB 0.3 practices were identified as relatively weak reaction. Key words: Histochemical, mucosubstance, zander (Stizostedion lucioperca)
