Ankara Tavşanında Konjunktiva ile İlişkili Lenfoid Doku

Öz

Bu çalışmada, Ankara tavşanında konjunktiva ile ilişkili lenfoid dokunun (Conjunctiva-associated lymphoid tissue,CALT) yapısı ışık ve elektron mikroskobik olarak incelendi. Araştırmada özel yetiştiricilerden sağlanan 10 adet sağlıklı,erişkin Ankara tavşanı kullanıldı. Asetik asit ile yapılan incelemede konjunktivanın lenfoid ve non-lenfoid bölgeler içerdiği gözlendi. Agregat lenf folliküllerinin nazolakrimal punktum çevresinde kümelendiği belirlendi. Histolojik olarak agregatlenf foliküllerinin epitele yakınlaştığı ve folikül ile ilişkili epiteli (Follicle-associated epithelium, FAE) oluşturduğu görüldü.Bu foliküller germinal merkez, korona, subepiteliyal dom bölgesi ve interfoliküler alanlardan oluşmaktaydı. Dom bölgesini örten FAE, kadeh hücresi içermeyen tek katlı yassı epitelden meydana gelirken; lenfoid yapı içermeyen bölge yapısında kadeh hücreleri bulunan yalancı çok katlı pirizmatik epitel ile örtülüydü. İnterfoliküler alanlarda ve folliküllerin dipkısımlarında yüksek endoteliyal venüllere rastlandı. İnce yapı düzeyinde, FAE’de elektron yoğun, ince ve dar bir sitoplazmaya sahip olan membranöz hücreler (M hücreleri) görüldü. Bu hücreler apikal membranında kısa ve düzensizmikrofoldlar, sitoplazmasında vezikül ve vakuoller ile karakterizeydi. M hücrelerinin bazolateralinde ise lenfositler vemakrofajlar görüldü. Sonuç olarak, Ankara tavşanında CALT’ın, mukoza ile ilişkili lenfoid dokuların karakteristik özelliklerine sahip olduğu belirlendi
