A comparison study was made of staining for immunoglobulin by immunofluorescence and immunoperoxidase in 23 lymph node biopsies. Cryostat sections were stained for immunoglobulins using a direct technique while paraffin-embedded sections were stained for immunoglobulins using the peroxidase-antiperoxidase (PAP) technique. Of 23 cases studied, including seven reactive hyperplasias and 16 lymphoid cancers, there was agreement between the two techniques in 18 cases. Nine of 14 non-Hodgkin's lymphomas showed agreement of results. All reactive hyperplasias showed complete agreement and had a distinctive pattern by both immunofluorescence and immunoperoxidase. Fixation, reagent specificity, and sensitivity of the methods may account for some of the discrepancies noted. Immunoperoxidase staining may be a useful diagnostic aid, particularly when immunofluorescent staining is not possible.

The occurrence and pattern of cytoplasmic muramidase containing histiocytes were studied by the unlabeled antibody peroxidase-antiperoxidase method in biopsy material from patients with Hodgkin's disease, non-Hodgkin's lymphomas, and reactive hyperplasia. The majority of lymph nodes from patients with Hodgkin's disease, nodular lymphoma, and reactive hyperplasia gave positive staining reactions when tested in this manner. Differences in the staining pattern were observed for the different conditions studied. In general, stain positive cells occurred in one of the following four patterns: nodular, dispersed, aggregating without background stain, or aggregating with background stain (mottling pattern). The nodular and aggregating without background stain patterns were not specific and were seen in various conditions. The dispersed pattern, however, was observed only in some cases of non-Hodgkin's diffuse lymphomas, suggesting a subgroup of tumors characterized by active participation of reactive histiocytes. The mottling pattern was virtually limited to Hodgkin's disease. Since the mottling pattern appeared to be produced by virtue of a large amount of extracellular muramidase, the elevation of the serum muramidase level in Hodgkin's disease may be related to enzymatically active secretory histiocytes. Moreover, the mottling staining pattern was observed frequently in the lymphocytic predominance and nodular sclerosis type of Hodgkin's disease, but relatively infrequently in the mixed cellularity or lymphocytic depletion types, suggesting that the variation in histiocytic activity may be related to the course of the disease. The decreased staining reaction observed in the latter two categories could not be accounted for by a decrease in the numbers of histiocytic cells in hematoxylin and eosin stained sections, suggesting that release or synthesis may be defective in those unfavorable types of Hodgkin's disease.

The immunogold-silver staining (IGSS) method is a new immunostaining technique with much enhanced sensitivity for demonstration of antigens in paraffin sections. A series of 10 non-Hodgkin's lymphomas of B cell type were stained for surface membrane immunoglobulins by the IGSS and peroxidase-antiperoxidase (PAP) methods using paraffin sections and polyclonal primary antisera. The resulting staining patterns were compared with those obtained using frozen sections of the same tissues, monoclonal antibodies and the immunoperoxidase technique. The IGSS method gave a clear demonstration of surface membrane immunoglobulins in neoplastic lymphocytes using paraffin sections and the pattern of staining achieved was comparable to that obtained by the immunoperoxidase technique employing frozen sections and monoclonal antibodies. PAP staining of paraffin sections consistently failed to demonstrate the presence of any surface membrane immunoglobulin. The IGSS method provides a new approach to the diagnosis of B cell lymphomas in which routinely fixed and processed tissues may be employed to demonstrate monoclonality.

The origin of the Reed-Sternberg cells of Hodgkin's disease is controversial with proponents of transformed lymphocyte and macrophage histiocyte derivations. Lectin receptors are potentially useful new cell markers in the investigation of lymphoproliferative disease. In this study, the lectin-binding properties of the Reed-Sternberg cell were investigated in an effort to clarify the cell of origin. Utilizing a simple peroxidase technique applicable to formalin-fixed, paraffin-embedded tissue, lectin binding was studied in 13 cases of Hodgkin's disease. Reed-Sternberg cells were found to bind cytoplasmic concanavalin A, but not Arachis hypogaea (peanut agglutinin) or Lotus tetragonolobus (asparagus pea). These are the lectin-binding properties of macrophage histiocytes rather than transformed lymphocytes. Lectin-binding studies support the macrophage origin of the neoplastic cells of Hodgkin's disease.

Lymphoma-associated antigen (LAA) was isolated from lymph nodes of confirmed Hodgkin's and non-Hodgkin's lymphomas by saline extraction, centrifugation and ammonium sulphate fractionation and then purified by G-200 Sephadex chromatography which revealed its mol.wt at 29 K daltons. By sucrose density-gradient centrifugation the mol.wt of LAA was 43 K daltons. Physicochemical properties of LAA were determined. In polyacrylamide gel LAA separated as a discrete protein with electrophoretic mobility of alpha-globulin at pH 8.6. The pI was 5.04 and sedimentation coefficient between 3S-4S. Xenogeneic antiserum was raised in rabbits and purified by cross adsorption and affinity chromatography. By immunochemical methods, LAA was detected in the sera and body fluids of most lymphoma patients and was absent from normal individuals and patients with other types of cancer. A radioimmunoassay procedure was developed and preliminary studies revealed that the lymphoma sera at 1:5 and 1:10 dilution inhibited the binding of labelled LAA by antibody, whereas the sera of normals and controls exhibited no such inhibition. The sensitivity of this assay was 22 ng ml-1. The serum LAA levels were in the range of 187-1500 ng ml-1. These results were also confirmed by the indirect inhibition assay using conjugated peroxidase. Serial determination of serum LAA by RIA indicated a positive correlation with the course of disease.

Malignant and non-neoplastic cells in 38 cases of highly malignant non-Hodgkin lymphomas: 3 centrocytic anaplastic, 18 centroblastic, 13 immunoblastic and 4 lymphoblastic (according to the Kiel classification) were immunophenotyped in cryosections and cell suspensions by means of monoclonal antibodies. Additionally, cell cycle analysis on cell suspensions was performed by DNA flow cytofluorometry. In 33 (87%) lymphomas the malignant cells expressed monoclonal surface immunoglobulin (Ig), which indicated B-cell origin of tumors. In 7 of the 19 B-cell lymphomas tested by the peroxidase-antiperoxidase method, cytoplasmic Ig was found. Four lymphomas were of T-cell and one of non-B/non-T-cell origin. In II B-cell and 2 lymphoblastic non-B-cell tumors, common acute lymphoblastic leukemia antigen (CALLA) was found. In 25 of 30 studied NHL the malignant cells expressed receptor for transferrin and in 19 of 28 cases a high percentage of cells in S-phase (greater than 10.85%) was found. Number and distribution as well as type of non-B-cells infiltrating B-cell-derived lymphomas varied considerably from case to case. Among these cells Leu 3+ (T helper/inducer) cells predominated. Leu 2+ (T suppressor/cytotoxic) and Leu 7+ (natural killer and killer) cells constituted less numerous groups. Correlation of cytodiagnostic analyses with clinical observations indicates that high content of infiltrating T cells may be a favorable prognostic feature in highly malignant B-cell lymphomas.

To investigate the specificity of terminal deoxynucleotidyl transferase (TdT) as a marker for lymphoblastic lymphoma in the non-Hodgkin's lymphomas, the authors assayed malignant cells from 142 patients with non-Hodgkin's malignant lymphoma, as well as cells from normal lymphoid tissue controls. Neoplastic cells from all 25 patients with lymphoblastic lymphoma were TdT positive. Of the remaining 117 patients with malignant lymphoma of other histologic subtypes, only one patient, with diffuse, large cell immunoblastic lymphoma, had TdT-positive cells. This patient's cells had positive results only by the enzyme assay and were TdT-negative by both immunofluorescence and immunoperoxidase assays. Of 56 patients whose cells were studied by both enzyme assay and an immunoassay method for TdT detection, a discordant result was obtained only on cells from the previously mentioned patient with large cell immunoblastic lymphoma. To determine the optimal immunoassay method, the authors studied malignant cells from 24 patients with non-Hodgkin's lymphoma for the presence of TdT by three different methods: immunofluorescence, peroxidase-antiperoxidase, and avidin-biotin-complex immunoperoxidase. Fifteen of the 24 patients had lymphoblastic lymphoma. The avidin-biotin-complex method produced superior staining, with no false-negative results. False-negative results were seen with both the immunofluorescence and peroxidase-antiperoxidase methods. Other advantages of the avidin-biotin-complex method included a marked decrease in background and non-specific staining and the ability to use higher dilutions of antisera.

The tissue distribution of fibronectin (FN) was examined using a commercial anti-FN serum, the peroxidase-anti-peroxidase (PaP) technique, and paraffin sections of 22 lymph nodes affected by Hodgkin's disease. Vascular basement membranes and reticulin fibres are selectively stained and their structural changes in this pathological condition become readily visible. In contrast to the normal lymph node and to Hodgkin's disease with lymphocytic predominance, cases of mixed cellularity disease contain individual and focally grouped cells displaying intracytoplasmic FN. In nodular sclerosis these cells with fibroblast morphology are consistently numerous in the marginal zones of the cellular nodes. Strongly reacting mastocytes probably absorbed the applied antiserum non-immunologically. All the other cell types giving rise to the varying appearances of Hodgkin's lesions are consistently negative with respect to intracellular FN, including all forms of Hodgkin cells. We conclude that in Hodgkin's disease the immigration of FN-secreting fibroblasts is an integral part of the early sclerosing reaction, which in itself is a defence/repair mechanism closely related to scar formation.

A series of 45 lymph nodes involved by Hodgkin's disease have been examined by means of the unlabelled antibody peroxidase-antiperoxidase (PAP) method for the demonstration of factor VIII-related antigen (F VIII R Ag). In addition, five lymph nodes showing reactive follicular hyperplasia were studied. In the specimens of nodular sclerosing Hodgkin's disease, many blood vessels were present, as demonstrated by virtue of F VIII R Ag in endothelial cells. These vessels were present within and, especially, around the nodules in this subtype; in addition the fibrous trabeculae were densely vascular. High vascularity was also a feature of specimens of the cellular variant of nodular sclerosing Hodgkin's disease. However, the other three Rye subtypes of the disease showed a striking paucity of F VIII R Ag-positive blood vessels. The reactive nodes showed numerous vessels around and between follicles but the lymph sinuses were consistently negative. Mast cells were present in all specimens but were especially frequent within and adjacent to the sinuses in reactive specimens; they were strongly positive for the F VIII R Ag, their staining being abolished by pre-adsorption of the primary antiserum with factor VIII itself.

Sixty-six children with acute lymphatic leukemia (ALL), 26 adults with ALL and 47 adults with acute myeloid leukemia (AML) were subclassified according to the classifications French-American-British (FAB) and World-Health-Organization (WHO). Nine immunological markers and 6 cytochemical stains were also used. The reproducibility of the WHO classification of the smears performed independently twice by one observer was 93%, but that between two observers only 78%. Three patients considered ALL by A were called AML by B, but all three had the common acute leukemia antigen, CALLA. In the group of 87 patients considered ALL by B, only 74 were classified ALL by A, but of the 13 non-ALL B, none had the CALLA. Ten of these thirteen patients had myeloid markers such as Philadelphia chromosomes, peroxidase or Sudan Black B positive reactions, or Fc and C3 receptors. The remaining 3 patients were non-Hodgkin lymphoma with B-cell markers. None of the 47 cases classified as AML had CALLA. Seventeen of nineteen myeloblastic leukemias (M2, FAB) had a myeloid antigen (Mag) and 13 of 15 myelomonocytic leukemias (M4, FAB) had, in addition, Fc and C3 receptors.
