Leukocyte migration inhibitory factor (LMIF) production in mixed lymphocyte culture (MLC) reactions is the result of cellular interactions based on two separate phenomena: the capacity of lymphocytes to stimulate in MLC, and the capacity of lymphocytes to respond in MLC. Puromycin-treated lymphocytes are capable of stimulating allogeneic cells for LMIF production, but are unable to respond with synthesis of LMIF (one-way MLC-LMIF test). We have studied the stimulating and responding capacity of lymphocytes from patients with different immunodeficiency syndromes in a one-way MLC-LMIF assay. Lymphocytes from patients known to have qualitative and quantitative defects of T cell or B cell functions (Hodgkin's disease, mycosis fungoides, thymoma, chronic lymphatic leukemia) were found to respond poorly as measured by mediator production although their stimulating fuction was frequently retained. Patients with advanced solid tumors often had both MLC-stimulating and responding functions depressed. There was no apparent correlation between mitogen response and MLC-induced LMIF responses or between MLC proliferative response (as measured by thymidine incorporation) and mediator production. Studying of stimulatory and responding capacity of lymphocytes in the MLC-LMIF assay provides a new tool for assessing immunocompetence and allows for in vitro evaluation of cellular interactions that may play an important role in vivo.

There is considerable circumstantial evidence relating neoplasia to glomerular injury. Recently, more convincing evidence has been derived from the demonstration of tumor-associated antigen or antibody to such antigen, in relation to glomerular basement membranes in four patients with glomerular injury and cancer. The most common form of glomerulopathy reported in patients with carcinoma has been membranous glomerulonephritis. However, increased mesangial cells and matrix have also been found in some patients with hematuria and progressive renal failure. In contrast, most patients with Hodgkin's disease and glomerulopathy have had the minimal lesion-type nephrotic syndrome, which has usually responded to successful treatment of the Hodgkin's disease. Glomerular abnormalities have also been reported with chronic lymphocytic leukemia, lymphosarcoma, Waldenstrom's macroglobulinemia, and benign tumors. When there is no apparent cause, proteinuria with or without hematuria or impaired renal function should suggest the possibility of associated neoplasia, particularly in elderly patients.

Infection of cells of the Epstein-Barr virus (EBV)-negative human B-lymphoma lines BJAB and Ramos with EBV preparations from P3HR-1 or B 95-8 cells converted these cells to EBV genome carriers expressing Epstein-Barr nuclear antigen (EBNA) in almost 100% of these cells. Induction of these cells as well as of clones from P3HR-1 EBV-converted BJAB cells with iododeoxyuridine, aminopterin, and hypoxanthine resulted in the appearance of a nuclear antigen in about 1-6% of the cells 1-4 days after induction. The antigen is different from known EBV-induced antigens like EBNA, viral capsid antigen (VCA) or the D- and R-subspecificities of the early antigen (EA) complex. It is demonstrated by indirect immunofluorescence and inactivated after acetone fixation. The antigen was not detectable after induction of uninfected BJAB and Ramos cells nor has it been found in noninduced or induced P3HR-1 and Raji cells. Thus, it appears that EBV-infection mediates the expression of this antigen, for which the name TINA (transiently induced nuclear antigen) is suggested. Sera reacting against TINA generally contained high antibody titers against EBV-induced EA. Only a limited number of highly EA-reactive sera, however, were also positive for TINA. Among 200 sera tested thus far, TINA reactivity was most frequently observed in sera of patients with nasopharyngeal carcinoma (7 out of 28), in sera of the only two patients with immunoblastoma tested and occasionally in sera from patients with Hodgkin's disease and chronic lymphatic leukemia. Among 70 sera from nontumor patients, TINA reactivity was observed three times: two patients suffered from "chronic" infectious mononucleosis, the other revealed persistent splenomegaly.

Myeloid and lymphoid stem cell colony formation (GM-CFU) and L-CFU) was studied in patients with lymphoproliferative diseases, aplastic anemia and other hematological abnormalities. Most patients with acute lymphatic leukemia had low number of L-CFU with decreased or normal GM-CFU, while in Hodgkin's disease and chronic lymphatic leukemia L-CFU growth was very poor with only minor abnormalities of GM-CFU formation. Aplastic anemia was characterized by a decreased GM-CFU and normal L-CFU. Coculture studies suggested that a diminished colony formation may be linked to circulating lymphocytes that inhibit L-CFU as well as the reduction in number of precursor cells.

The dihydrofolate reductase activity has been studied cytochemically in various haematological diseases. The variation between normal controls, Hodgkin's disease, myeloma, polycythaemia vera, chronic lymphocytic leukaemia and chronic myeloid leukamia was not significant, comparing the same type of cells. In acute myeloid leukaemia and acute lymphoblastic leukaemia the blast cells were weakly positive or negative. This finding is very interesting as the blast cells are capable of division. Probably the dihydrofolate reductase appears in the blast cells in some stage of mitosis. Lymphocytes stimulated by phytohaemagglutinin showed increased enzyme activity compared with normal non-stimulated lymphocytes. The "blast like" cells were more strongly positive than the blast cells of leukaemic patients. The patients with acute lymphoblastic leukaemia or acute myeloid leukaemia treated with methotrexate showed increased dihydrofolate reductase activity cytochemically.

Lymphoid cells obtained from spleens of patients with lymphomas or leukemias were studied for the presence of heterophile (Paul-Bunnell (P-B)) antigen. A mixed agglutination (MA) test was established utilizing monolayers of cells attached to poly-L-lysine-coated wells of plastic U plates. After incubation of the monolayers with infectious mononeucleosis (IM) sera, indicator cells, sheep, or trypsinized bovine erythrocytes were added. The results were assessed according to sedimentation patterns of the indicator cells on the monolayers. Positive MA reactions were shown to be due to specific binding of P-B antibodies to the corresponding antigens on the spleen cells. Positive results were obtained with 15 of 37 spleens from patients with Hodgkin's disease, 5 of 8 lymphoma spleens, 4 of 15 chronic myelocytic leukemia spleens and 2 of 4 chronic lymphocytic leukemia spleens. Only 2 of 25 spleens from patients with various other diseases and 1 of 26 apparently normal thymus specimens gave positive results. This study confirmed demonstration of P-B antigen in lymphoma and leukemia by means of absorption experiments, which was reported previously.

When ficoll purified peripheral blood lymphocytes were treated with fluorescein conjugated lectins from lentils (LCH), castor beans (RCA) and phaseolus coccineus beans (L-and E-PHA) for 15 min and the percentages of the cap forming cells were examined, the values of leukemic lymphocytes were reduced compared to the values obtained with normal lymphocytes. The reduction was more than half in patients with acute and chronic myelogenous leukemia and immunoblastoma, it was only one quarter in patients with chronic lymphocytic leukemia, Hodgkin's disease and lymphosarcoma. The lowest number of cap forming cells was found in lymphoblasts of established lymphoblastoid cell lines. The four different lectins showed nearly the same capacity in the induction of caps. After successive binding, the different lectins showed cocapping on the lymphocyte surface.

The diseases discussed in this paper include chronic lymphocytic leukemia, monocytic leukemia, chronic granulocytic leukemia, acute leukemias, Hodgkin's disease, and lymphosarcoma. Cutaneous manifestations of these disorders are often sufficiently different to indicate a certain leukemia or lymphoma. The cutaneous manifestations of leukemias and lymphomas may help the clinician suspect the diagnosis.

Leucocytes of normal persons and patients with acute and chronic granulocytic leukemia, chronic lymphocytic leukemia, and non-Hodgkin lymphoma were separated into subfractions by centrifugation in discontinuous Ficoll density gradient. Osmotic resistance was examined in hypotonic NaCl solutions with decreasing concentration and by determining LDH activity in the supernatant. Suspensions of myelocytes, polymorphnuclear granulocytes, and lymphocytes of normal persons and patients with chronic lymphocytic leukemia demonstrated the same osmotic resistance. Only myeloblasts were osmotically less fragile, and tumor cells of non-Hodgkin lymphoma more fragile.

Despite the incomparability in the reporting of leukemia and lymphoma incidence among populations and the relative rarity of these diseases, real differences in rates are discernible from available data. In general, the incidence of each of the leukemias and lymphomas is lower in Japan than in other Pacific rim populations whose rates are known. Particularly striking is the low incidence of CLL in Japan. Among Japanese in Hawaii, rates of some of these cancers (lymphosarcoma, CML) approach those of whites, whereas rates of other cancers (Hodgkin's disease, multiple myeloma, ALL, CLL, and AML) more closely resemble those of native Japanese. The number of Chinese living in countries served by population-based cancer reporting systems is too small for any firm conclusions to be made about leukemia and lymphoma incidence in this group. The incidence of these diseases in certain other nonwhite Pacific rim residents (i.e., Mexican Americans, blacks, and Maoris) is, by and large, similar to that of whites.
