| immunological and ultrastructural characterization of true histiocytic lymphoma in the northern pike, esox lucius l. | an epidemic of a malignant neoplasm occurs in northern pike, esox lucius l., from the aland islands of finland. the neoplasm is morphologically similar to other pike hemic tumors reported in other areas of the world. pike normal tissues showed evolutionary conservation with the mammalian intermediate filament proteins cytokeratin, desmin, vimentin, neurofilament protein, and glial fibrillary acidic protein; tumor cells are positive for vimentin, suggesting that the neoplasm is of mesenchymal ori ... | 1990 | 2201440 |
| cutaneous tumor of northern pike, esox lucius l. ii. expression of surface and cytoplasmic immunoglobulins and alpha-naphthyl acetate esterase by mononuclear cells from lymphoid tissues and tumor. | rabbit anti-pike igm antibodies showed that up to 95% of mononuclear (mn) cells isolated on ficoll-isopaque gradients from peripheral blood, spleen, and head kidney of northern pikes carrying cutaneous tumors were surface (sig) and cytoplasmic (cig) immunoglobulin positive by indirect immunofluorescence. on the contrary, rabbit anti-winter flounder igm antibodies gave totally negative results. monoclonal anti-carp igm antibodies stained approximately 40-56% of peripheral blood, splenic, and head ... | 1988 | 3350193 |
| immunological classification of a pike lymphoma. | monoclonal and polyclonal antibodies against mammalian intermediate filament (if) proteins were used to demonstrate if expression in tissues and lymphoma tumors of northern pikes, esox lucius l., from the aland islands of finland by indirect immunofluorescence microscopy. frozen sections of pike tissues demonstrated ifs in a manner confirming their evolutionary conservation and subclass specificity. tumor cells showed morphological resemblance to head kidney cells and were positive for vimentin ... | 1986 | 3765362 |
