Studies on Morphology and Cytochemistry in Blood Cells of AyuPlecoglossus altivelis altivelis

[摘要] References(22)Cited-By(1)Peripheral blood cells from ayu, Plecoglossus altivelisaltivelis, were separated using a density gradient. Blood cells were thensmeared using Shandon Cytospin and subjected to cytochemical staining. Blood cells werecategorized based on morphological and cytochemical characteristics, and the densityfractionation range and nucleus area/cell area ratio were observed. Lymphocytes aredistinguished from neutrophils by their basophilic cytoplasm and Golgi-like field. Thefeatures of chromatin in thrombocytes are different from those of lymphocytes orneutrophils, but some small neutrophils have similar chromatin. Therefore, it is necessaryto perform peroxidase staining to distinguish small neutrophils from thrombocytes.Basophils have large basophilic granules in cytoplasm. Based on density fractionation ofblood cells, thrombocytes in the low-density area were separated from other blood cells.Identification of peripheral blood cells from ayu was possible with these stainingmethods. Monocytes/macrophages from spleen are specifically positive for esterase stainingby α-naphthyl butyrate. As a result, thrombocytes, lymphocytes, neutrophils, basophils andmonocytes/macrophages were identified in smears from peripheral blood or spleen tissue. Inthis paper, we confirmed that the peripheral blood corpuscles of ayu are able to beidentified using the present staining methods.
