    A COMPARATIVE STUDY ON THE HISTOLOGICAL STRUCTURE OF THE SPLEEN IN THE OSTRICH (STRUTHIO CAMELUS), THE KESTREL (FALCO TINNUNCULUS) AND THE OSPREY (PANDION HALIAETUS)
    (Akademiai Kiado Rt, 2011) Kozlu, Tolunay; Sari, Ebru Karadag; Bozkurt, Yesim Akaydin; Altunay, H.
    The spleen structurally and functionally belongs to the hematopoietic organs and is also an important component of the reticuloendothelial system, which is known to play a major role in host defense. The histological structure of the spleen was investigated in the ostrich, a non-flying bird, the kestrel, a raptor, and the osprey, a fish-eating bird of prey (fish eagle). For this purpose, Mallory's modified triple stain, methyl green-pyronin and silver stain were used. Germinal centers were not present in the spleen of the osprey. In the spleen of the kestrel, penicillar arterioles and the surrounding lymphoid tissue were markedly dense. Compared to the other two birds, the red and white pulps were clearly distinguishable in the spleen of the ostrich.

    Histological and Histochemical Studies on the Harderian Gland of the Osprey (Pandion haliaetus)
    (Medwell Online, 2010) Kozlu, Tolunay; Bozkurt, Yesim Akaydin; Altunay, Hikmet; Sari, Ebru Karadag
    The aim of the present study was to demonstrate the histological and histochemical structure of the Harderian gland of the osprey. The Harderian gland of the osprey (Pandion haliaetus) is a tubuloalveolar gland. The gland lumen was lined by columnar epithelial cells of varying height which were filled with secretory vesicles and by dark cells found among these cells. It was observed that the secretion was produced in the corpus glandulae and was extracted by primary and secondary ducts. In addition, plasma cells were present in interlobular trabeculae. Histochemical stainings which were performed to determine the character of the glandular secretion revealed that the majority of the secretory cells contained only acidic mucins whilst the remaining secretory cells contained both neutral and acidic mucins. Furthermore, it was observed that some cells of the primary and secondary ducts epithelium had secretory vesicles containing only neutral mucin. The presence of reticulum fibres was demonstrated in the interlobular trabeculae.

    Immunohistochemical staining of cd3, cd79?cy and s-100 on bursa fabricius, thymus and spleen of turkeys (Meleagris gallapavo)
    (Agricultural Research Communication Centre, 2019) Kozlu, Tolunay; Sari, Ebru Karadag; Bozkurt, Yesim Akaydin; Kurtdede, Nevin
    Distribution of CD3, CD79 alpha cy and S-100, immunohistochemically, in the bursa of Fabricius, thymus and spleen has not been reported in turkeys. Therefore, we determined the localisation of anti-CD3 protein antibodies for mature T-lymphocytes, anti-CD79 alpha cy antibodies for B-lymphocytes and anti-S-100 protein antibodies for follicular dentritic cells in the bursa of Fabricius, thymus and spleen, which are the lymphoid organs, in a study sample of turkeys. Triple staining method was applied to demonstrate the general structure. Moreover, in all the organs positive reactions were observed with the CD3, CD79 alpha cy and S-100 antibodies. It was also found that similar areas had a positive reaction with CD79 alpha cy and S-100 in all of the tested organs. It was remarkable that CD79 alpha cy reacted positively on Hassall's corpuscles (strongly) and the reticular cells (weakly) in the medulla of the thymus instead of the B-lymphocyte positive areas.
