Abstract

This study was carried out to investigate the anatomical, histological and histochemical properties of superficial and lacrimal glands in tuj sheep. A total of 10 superficial and lacrimal glands were used in the study. Anatomical, histological and histochemical techniques were applied to the glands. As a result, the superficial gland was found to be 18-19 mm long, 8-9 mm wide and 3-4 mm thick. Lacrimal gland was determined as 20-23 mm in length, 17-26 mm in width and 3-4 mm in thickness. Hyaline cartilage was observed at the base of the superficial gland. Superficial and lacrimal glands were found to consist of acinuses, interlobular and intralobular ducts and many blood vessels. While Periodic Acid Schiff (PAS) positive reaction was observed in superficial glands, no reaction was observed in goblet cells in lacrimal glands. The secretion in the interlobular and intralobular ducts of superficial and lacrimal glands showed PAS positive reaction. In both glands, elastic fibers around the ducts and vessels showed positive reaction to orcein staining. As a result, when the values given in the literature were taken into consideration, it was seen that the length value of the superficial gland was low and the width and thickness values were high. While the length of the lacrimal gland was in the middle of the values given in the literature, it was found to have high values in terms of width and thickness. It is thought that this study will contribute to veterinary medicine regarding eye diseases and eye-related surgeries.

Tuj Koyunlarında Superficial ve Lakrimal Bezlerin Anatomik ve Histolojik Yapılarının İncelenmesi

Abstract

Bu çalışma, tuj koyunlarında superficial ve lakrimal bezlerin anatomik, histolojik ve histokimyasal özelliklerini araştırmak amacıyla yapıldı. Çalışmada toplam 10 adet yüzeysel ve lakrimal bez kullanıldı. Bezlere anatomik, histolojik ve histokimyasal teknikler uygulandı. Sonuç olarak, superficial bezin 18-19 mm uzunluğunda, 8-9 mm genişliğinde ve 3-4 mm kalınlığında olduğu tespit edildi. Lakrimal bez 20-23 mm uzunluk, 17-26 mm genişlik ve 3-4 mm kalınlık olarak belirlendi. Superficial bezin tabanında hiyalin kıkırdak gözlendi. Superficial ve lakrimal bezlerin asinüsler, interlobüler ve intralobüler kanallar ve çok sayıda kan damarından oluştuğu tespit edildi. Superficial bezlerde Periyodik Asit Schiff (PAS) pozitif reaksiyon gözlenirken, lakrimal bezlerde goblet hücrelerinde reaksiyon gözlenmedi. Superficial ve lakrimal bezlerin interlobüler ve intralobüler kanallarındaki salgı PAS pozitif reaksiyon gösterdi. Her iki bezde de kanallar ve damarlar etrafındaki elastik iplikler orcein boyamasına pozitif reaksiyon gösterdi. Sonuç olarak literatürlerde verilen değerler dikkate alındığında superficial bezin uzunluk değerinin düşük, genişlik ve kalınlık değerlerinin ise yüksek olduğu görüldü. Lakrimal bezin uzunluğu literatürde verilen değerlerin ortasında yer alırken, genişlik ve kalınlık bakımından yüksek değerlere sahip olduğu tespit edildi. Bu çalışmanın veteriner hekimlik mesleğine katkı sağlayacağı düşünülmektedir.
