Oklu kirpilerde (Hystrix cristata) karaciğerin makro - anatomik ve ışık mikroskobik Yapısı

Bu çalışmada, oklu kirpilerde karaciğerin makro-anatomik ve ışık mikroskobik yapısı incelenmiştir. Bu amaçla 5 adet erişkin oklu kirpi (Hystrix cristata) kullanılmıştır. Oklu kirpilerde karaciğerin sağ lobu (lobus hepatis dexter), lateral ve medial olmak üzere 2 parça halindeyken, sol lop (lobus hepatis sinister) planum medianum’un solunda ve tek parçadan oluşmuştu. Lobus quadratus derin bir çentikle iki parçaya ayrılmıştı. Lobus caudatus karaciğerin en küçük lobu olup, iki uzantıya sahipti. Vesica fellea’nın varlığı gözlendi. Karaciğerin morfolojik üniteleri olan lobuli hepatis’lerin poligonal şekilli olduğu saptandı. Lopçukların merkezinde vena centralis görüldü. Karaciğerde hepatositler ve sinüzoid duvarında Kupffer hücreleri görüldü. Hepatositler poligonal şekilli olup farklı hücre sınırlarına sahipti. Sonuç olarak, oklu kirpi karaciğerinin hem anatomik hem de histolojik temel özellikleri vurgulanmış, oklu kirpi ile diğer rodentialar arasındaki bazı benzerlik ve farklılıklar saptanmıştır.

Macro - anatomical and light microscopical structures of liver in porcupine (Hystrix cristata)

The aim of this study was to investigate the macro-anatomical and light microscopical structures of liver in the porcupines (Hystrix cristata). For this purpose, five adult porcupines were used. The right lobe (lobus hepatis dexter) was divided into lateral and medial lobules. The left lobe was located at the left side of the midline, and it was not divided. The quadrate lobe was divided into two components by a deep notch. The caudate lobe was the smallest lobe of porcupine liver and it had two processes. Gallbladder was present. Polygonal hepatic lobules were the morphological units of the liver. V. centralis was seen in the centre of lobulus. Hepatocytes and Kupffer cells were observed in the walls of sinusoids in the liver. Hepatocytes were polyhedral cells with distinct boundaries. In conclusion, both anatomical and histological funda-mental features of the liver of porcupine were stressed and, additionally, some similarities and differences were detected between porcupine and other rodentia.
