The lysozyme (muramidase) activity was measured in the sera of 84 dogs with neoplastic disease. Neoplasms included 32 lymphomas, 13 primary bone neoplasms, 5 melanomas, 5 thyroid neoplasms, 9 soft tissue sarcomas, 5 mast cell sarcomas, and 15 carcinomas. The sera from 21 healthy dogs served as
Nine cases of primary ovarian sarcoma were studied with a panel of 10 antibodies by using the avidin-biotin-complex immunoperoxidase technique. Original diagnoses included five mixed müllerian tumors (MMT) homologous type, two MMT heterologous type, and two pure sarcomas (PS). Cytokeratin
Seventeen meningeal tumors were examined for pathology with electron microscopy and immunohistochemistry including glial fibrillary acidic protein (GFAP), S-100 protein, muramidase, and factor VIII. These tumors included seven meningiomas, one hemangiopericytoma, three meningeal sarcomas (1
Infusion of cycloheximide i.v., an antibiotic known to inhibit synthesis of protein, at a rate of 0.2 mg/kg/hr, reliably caused lysis of fever in 15 chronically febrile patients with Hodgkin's disease who did not have detectable bacterial, fungal, or viral infection. Antipyretic effects were also
Eighty-two cases of giant cell tumor (GCT) were reviewed. Hematoxylin-eosin-and hematoxylin, phloxine, saffron, and alcian green-stained sections (82 cases) were examined for mitotic rate, the number of giant cells, and the pleomorphism of the stromal cells. In 29 cases, the tumor was stained for
The following enzyme activities were measured in cell lysates and supernatants from mouse peritoneal macrophages incubated with products of cultured tumour and other cells: acid phosphatase, beta-D-glucuronidase, N-acetyl-D-glucosaminidase, muramidase (lysozyme), lactic dehydrogenase (supernatant
This report describes four malignant tumors originating in infants, (one present at birth), for which a common origin is proposed. The common nature of these tumors was suggested by a remarkable similarity of histologic and ultrastructural features, including the presence of intracellular
A case of recurrent Hodgkin's disease of the "sarcomatoid" or "syncytial variant" type was seen that occurred as an extension from the mediastinum to a previously uninvolved extranodal site (breast) and pericardium after treatment of classical nodular sclerosing Hodgkin's disease based in the lymph
Clinical, microscopic, and immunohistochemical characteristics of 17 jaw sarcomas are reported. Histologic subtypes included chondroblastic (five), fibroblastic (five), osteoblastic (three), telangiectatic (one), parosteal (two), and chondrosarcoma (one). Reactivity for all antigenic markers in
Lysozyme is an innate non-immunologic antibacterial enzyme produced by the Paneth cells of the upper intestinal tract. Lysozyme is not normally secreted in the lower intestinal tract. Previous reports indicate, however, that lysozyme may be secreted by colorectal neoplasias. The aim was to audit
A small series of granulocytic sarcomas (GS) or 'chloromas' has been studied by means of conventional histology and immunohistochemistry. The latter was found to be most useful in the diagnosis and characterization of these neoplasms, which are rare in Great Britain. Polytypic antisera to leukocyte
Although it is well recognized that granulocytic sarcoma can cause localized lymphadenopathy, widespread nodal involvement by acute myelocytic leukemia (AML), clinically mimicking non-Hodgkin's lymphoma, has only been previously described twice. We report the clinicopathological, immunological, and
The literature dealing with the biochemical basis of bacteriolysis and its role in inflammation, infection and in post-infectious sequelae is reviewed and discussed. Bacteriolysis is an event that may occur when normal microbial multiplication is altered due to an uncontrolled activation of a series
