Reagents that recognize antigens on lymphoid cells in fixed and wax-embedded sections have been applied to a series of cases of non-Hodgkin's lymphomas. The panel consisted of MB1, 4KB5 (CD45r), LN1, L26 and MB2 which recognize antigens expressed predominantly on B-lymphocytes; UCHL1 and MT1 which recognize antigens expressed on T-lymphocytes and myeloid cells; antibodies recognizing the non-lineage antigens LeuM1 (CD15), BerH2 (CD30), anti-EMA; anti-lysozyme and MAC 387 which detect antigens present on some macrophages; and finally TAL1B5 (class II MHC), CAM 5.2 (low molecular weight cytokeratin) and PD7/26 + 2B11(CD45). Two hundred and four cases of non-Hodgkin's lymphoma have been studied, of which 158 had been fully characterized on frozen sections. The series was biased towards high-grade (n = 108) and T-cell (n = 44) tumours and these were largely prospectively accrued. It was found that discrimination between B-cell and T-cell lymphomas can be reliably achieved using these reagents and that a small panel (CD45, L26, MB2, MT1, UCHL1) is adequate for this purpose. Using the full range of reagents it is not possible to subdivide cases into groups that correspond with morphological subtypes of lymphoma. Although paraffin section immunohistochemistry is of value, the diagnosis of lymphoproliferative disorders must still be based upon the assessment of well fixed, carefully prepared tissue sections using conventional tinctorial methods.

We conducted a new chemotherapy, NEO-MAC OP-B (addition of etoposide and mitoxantrone to MACOP-B with half dose of methotrexate and half administration of doxorubicin), to reduce severe mucositis, which is a major toxic effect of MACOP-B, and to increase its effect with etoposide and mitoxantrone as new non-cross resistant drugs. Between Jan. 1989 and Mar. 1993, 12 patients with previously untreated advanced aggressive non-Hodgkin's lymphoma (NHL), 2 patients with adult T cell lymphoma, and 3 patients with relapsed NHL, were treated with NEO-MACOP-B. After termination of NEO-MACOP-B therapy, 83.3% of 12 patients with previously untreated NHL were in complete remission (CR). After median follow-up of 22 months, Kaplan-Meier estimates showed that overall survival of 12 previously untreated patients was 71.4%, and relapse-free survival of complete responder was 83.3%. Toxic effects on all 17 patients were moderate with a lower incidence of severe mucositis (only one patient with relatively severe stomatitis, WHO Grade 3). No treatment related deaths were observed. Thus, NEO-MACOP-B is an effective and safe treatment for advanced stage aggressive NHL.

Complement activation is involved in the initiation of inflammation and antibody-mediated demyelination in experimental autoimmune encephalomyelitis (EAE). We investigated the role of MAC in apoptosis in myelin-induced EAE in complement C5-deficient (C5-d) and C5-sufficient (C5-s) mice. The number of apoptotic cells assessed by TUNEL assay was significantly increased in C5-d mice during clinical recovery as compared with C5-s mice. Most of the apoptotic cells were lymphocytes, monocytes, and oligodendrocytes. DNA microarray was performed using total RNA extracted from spinal cords. Genes expressed higher in C5-s included members of the caspase (caspase 6, 7), TNF and TNFR families (CD27, FasL, lymphotoxin-beta R) and survivin. These results indicate that C5 and possibly MAC may be required for the limitation of inflammatory response within the central nervous system.
