Abstract

In this study, prenatal and postnatal development of rat tracheas were investigated using light microscopy. For this purpose, tracheas obtained from fetuses on the 7,10,13,15,17 th days of gestation and from newborn on 5,10 th days af¬ter birth were studied by histological methods. On the 7th day of gestation trachea had a simple co¬lumnar epithelium in the spreading mesenchyme. On the fetal 10th day, at trachea, there was multi-row epithelial tissue. On the 13th day of gestation, the pseudostratified Columnar epithelial tissue of trachea consisted of ciliated cells. Musculus trac-healis which consisted of myoblastswas first seen in this stage. On the fetal 15th day, mesenchimal cells which surrounded the trachea formed 4-5 centers of cartilage. The lining of the trachea was ciliated pseudostratified columnar epithelium and musculus trachealis was noticeable. Trachea had pseudostratified columnar epithelium that inclu¬ded goblet cells, at the 17th day of gestation. The cartilage of trachea appeared to be more differen-tiated.On postnatal 5th day and 10th day, trachea had ciliated simple columnar epithelium. In conc¬lusion, our opinion is that the findings obtained in this work will enlighten other morphological in¬vestigations related to the development of rat trac¬hea, and contribute to literature.

Özet

Bu çalışmada sıçan trakeasının prenatal ve postnatal gelişimi ışık mikroskobu seviyesinde in¬celenmiştir. Bu amaçla gebeliğin yedi, on, onüç, onbeş ve ony edinci'günlerindeki fetuslardan ve doğum sonrası beş ve onuncu günlerdeki yeni do¬ğanlardan alınan trakealar histolojik metodlarla incelenmiştir. Gebeliğin yedinci gününde yaygın mezenkim içindeki trakea tek katlı prizmatik epite-le sahiptir. Fetal onuncu günde trakeada çok katlı epitelial doku vardır. Gebeliğin onüçüncü günün¬de, trakeanm yalancı çok katlı epiteli silialı hücre¬lerden ibarettir. Muskulus trakealis ilk olarak bu safhada görülmüş ve myoblastlardan oluşmuştur. Fetal onbeşinci günde trakeayı çevreleyen mezen-kimal hücreler, 4-5 tane kıkırdaklaşma merkezi oluşturmuştur. Trakea örtüsü silialı yalancı çok katlı prizmatik epiteldir ve muskulus trakealis be¬lirgindir. Gebeliğin onyedinci gününde, trakea goblet hücreleri içeren yalancı çok katlı epitele sahiptir. Trakea kıkırdağının oldukça farklılaşmış olduğu görülmüştür. Postnatal beş ve onuncu günlerde trakea silialı tek katlı prizmatik epitele sahiptir. Sonuç olarak, bu çalışmada elde edilen bulguların sıçan trakeasının gelişimi ile ilgili di¬ğer morfolojik çalışmalara ışık tutacağı ve litera¬türe katkıda bulunacağı kanısını taşımaktayız.
