Öğe The determination of Alpha Naphthyl Acetate Esterase (ANAE) activities in the peripheral blood leukocytes of geese (Anser anser)(Ecole Nationale Veterinaire Toulouse, 2009) Sari, E. Karadag; Kozlu, T.; Kocamis, H.; Deprem, T.; Asti, R. N.; Nazli, M.The objectives of this study were to investigate the presence of the Alpha Naphthyl Acetate Esterase (ANAE) in peripheral blood leukocytes in goose and to determine the proportions of blood T lymphocytes with this method. Blood smears obtained from 15 geese. 10 month old, were incubated at various pHs (5.0, 5.4, 5.8. 6.2, 6.4. 6.8 and 7.2 for 3 or 6 hours with the enzyme substrate. The highest resolution and consequently the best determination of positive ANAE cells were obtained with pH 5.8 for an incubation period of 6 hours. Positive ANAE activity wits only recorded in monocytes and in some lymphocytes (T cells) according, a diffuse and a granular pattern respectively whereas granulocytes, thrombocytes and B lymphocytes appeared ANAE negative. The mean ratio of ANAE positive lymphocytes peripheral blood ill goose was 53.6 +/- 3.2% and exhibited weak inter-individual fluctuations (coefficient of variations: 5.9%). These results suggest that ANAE staining method could be easily and efficiently used for T cell counting in peripheral blood.Öğe The determination of Alpha Naphthyl Acetate Esterase (ANAE) activities in the peripheral blood leukocytes of geese {flnser anser)(2009) Sari, E.

The gland epithelium is composed of two different cell types, which can be classified as type I and type II. These cells contain dense secretory vesicles in their cytoplasm and they are connected laterally with desmosomes. At the basal site of these cells, myoepithelial cells are present. Plasma cells are observed in the subepithelial region of the gland. In the interlobular trabeculae, forming the gland stroma, fibroblasts, blood vessels and nerve fibres are included. Another important finding in the ostrich Harderian gland is the presence of homogeneous material.Öğe Histological and immunohistochemical studies of the structure of lymph nodes in Kilis goats(Taylor & Francis Ltd, 2014) Bozkurt, Y. A.; Kus, S.; Kozlu, T.; Basak, F.Ten healthy adult Kilis goat mesenteric lymph nodes were used to examine the general structure of lymph nodes, lymphocytes, plasma cells, reticular cells and reticular fibers using histological methods. We also detected T lymphocytes using anti-CD3 [SP7], anti-CD4 [74-12-4], mouse anti-bovine CD4 [CC30] and mouse anti-bovine CD8 [CC63] monoclonal antibodies (mAb); and B lymphocytes using anti-CD79a [HM57] mAb, macrophages using anti-macrophage [MAC387] mAb and follicular dendritic cells using anti-S100 polyclonal antibody (pAb). The distribution of these cells also was studied. Although the primer antibodies we used for CD3, CD8, CD79a, MAC387 and S100 worked well, the primer antibodies for CD4 were ineffective for paraffin embedded goat lymph nodes.
