In three patients with non-Hodgkin lymphomas and in one cell line (HPL-Hod) derived from pleural effusion cells of a patient with Hodgkin's disease, rearrangements of the long arm of chromosome No. 14(14q) were observed. These rearrangements appeared to be consistently associated with a 14q translocation, suggestive of occurrence of a break at 14q13. The translocation in an individual case could occur with 1p, 2q, 4q, and another 14q. A 14q13 translocation may be comparable with a 14q32 translocation, which has often been observed in various types of lymphoid malignancy.

As prognosis has improved over the last several years, an increasing incidence of meningeal involvement has been recognized in adult patients with acute leukemias and malignant lymphomas. In 210 patients evaluated retrospectively, the incidence of meningeal disease was 33% for patients with acute lymphocytic leukemia (ALL), 20% for patients with acute myelogenous leukemia (AML), 22% for patients with non-Hodgkin's lymphomas with an unfavorable histology (NHL), 3% for patients with chronic myelogenous leukemia (CML), and 1% for patients with chronic lymphocytic leukemia (CLL). In most patients, meningeal involvement appeared several months after diagnosis of acute leukemia, often preceding systemic relapse if bone marrow remission had been achieved before. Prophylactic treatment of the CNS was begun in eight patients with ALL or AML after bone marrow remission was achieved. Of these patients, three with ALL and one with AML were free of disease up to 2 years after diagnosis. Methods, benefits, and risks of prophylactic treatment of the CNS for adult patients are discussed in detail.

1. Kinetics of inactivation of sodium channels in myelinated nerve from Rana pipiens were studied at 4.5 degrees C using the voltage clamp technique of Dodge & Frankenhaeuser (1958).2. Potassium currents were blocked by cutting the internodes in 20 mM-TEA-Cl + 100 mM-KCl and by adding 12 mM-TEA-Cl to the external Ringer. Leakage and capacitative currents were subtracted electronically.3. Kinetics of recovery from inactivation of the sodium channels were studied by inactivating the channels with a large depolarizing prepulse and allowing the channels to recover at different potentials; the extent of recovery was measured by applying a test pulse at various times after the prepulse.4. Kinetics of development of inactivation were studied by two different methods. The first was to measure the decay of sodium current under a maintained depolarization. The second method was to measure the decay of the peak sodium current in a test pulse as a function of time after the onset of a maintained depolarization. These two methods yielded similar results for the kinetics of inactivation development.5. Contrary to expectations of the Hodgkin-Huxley formalism, the time course of recovery from and development of inactivation is not strictly exponential. Rather, recovery from complete inactivation shows an initial delay which depends on recovery potentials. Development of inactivation at a fixed potential exhibits at least two exponentials.6. The steady-state inactivation curve h(infinity)(E) is asymmetrical and is fitted better by 1/[1+exp (A(1)E+B(1)) +exp (A(2)E+B(2))] than by 1/[1+exp (AE+B)].7. Most of the above kinetic observation on inactivation can be fitted by the following modification of the h system of the Hodgkin-Huxley formalism: [Formula: see text]8. In the analysis it was not necessary to modify the concept of two separate processes, activation and inactivation, governing the opening and closing of the sodium channels.

Lymphocytes from tumour-bearing lymph nodes in 15 patients with Hodgkin's disease, and lymphocytes from 6 spleens infiltrated by Hodgkin's tissue and 6 tumour-free spleens were studied using T and B lymphocyte markers. For comparison, lymphocytes from 16 tumour-free lymph nodes were similarly assessed. It was found that the tumour-bearing nodes showed a predominance of T lymphocytes compared with the control nodes, whereas in involved splenic tissue the proportion of T lymphocytes was slightly reduced compared with uninvolved spleens.

A study of some immunologic in vitro and in vivo changes during the course of chemotherapy in 17 cases of advanced Hodgkin's disease was made. Skin testing with PPD, candida albicans and streptodornase antigens was studied together with studies of B and T cell numbers in the blood and responses to migration inhibition testing for PPD and PHA. An excellent correlation was found between recovery of normal immunologic responses and clinical remission despite the use of immunosuppressive chemotherapy.

Immunohistochemical and histoogical studies have been performed on paraffin sections of 19 cases of non-Hodgkin's lymphoma (NHL). All the cases were lymphocytic in type and, on the basis of the National Lymphoma Investigation classification, 11 were follicular (six small, three mixed small and large, and two large cell types) and eight were diffuse (four intermediate, three poorly and one well-differentiated types). Marshall's metalophil method revealed a population of dendritic histiocytes in and around the follicles of follicular lymphomas. The distribution of the dendritic cells within the neoplastic follicles resembled the distribution of similar cells in reactive follicles, lending support to the concept of an origin for lymphoma follicles from their reactive counterparts. In the diffuse lesions the dendritic cells were large and more pleomorphic than in the follicular lesions, but these features were not so pronounced as those previously observed in Hodgkin's disease. The PAP sequence was used to demonstrate Ig, and as judged by the types of light and heavy chains in the lymphoma cells, the cases were divided into three groups: Group 1 (eight cases) in which the lymphoma cells contained monotypic Ig; Group 2 (six cases) in which monotypic Ig was probably present; and Group 3 (four cases) where no evidence of monotypic Ig secretion was found. Monotypic Ig was most commonly found in follicular lymphomas, mu kappa secretion being the most frequently identified combination of heavy and light chains. The majority of cases (73 per cent.) were thus clearly derived from B lymphocytes. However, the fact that monoclonality was evident in only a proportion of cases suggested that lymphomas may be polyclonal initially and proportion of cases suggested that lymphomas may be polyclonal initially and that monoclonality is a later development. In addition to the lymphoma cells, normal mature plasma cells containing a high concentration of intracellular Ig were present in all but one of the lesions. The Ig was polytypic, cells containing kappa and lambda chains being present in roughly equal numbers and gamma chains pre-dominating. Extracellular Ig (gamma, mu, kappa, lambda) was also present in many lesions. Collections of small non-lymphomatous lymphocytes were also present in all cases. In eight lesions these appeared to have polytypic surface Ig (mu, kappa, lambda). Dendritic cells mingled with these lymphocytes. Collections of small lymphocytes non-reactive for Ig were also present. These had no association with dendritic histiocytes and might have been T cells. It is concluded that in most cases immunohistochemistry alone provides an insufficient basis for the diagnosis of lymphoma and that disturbance of cellular morphology and tissue architecture remain the most useful criteria on which the diagnosis of lymphoma rests.

Evaluation and classification of malignant lymphomas have changed decisevely in recent years. It was especially through immunology that these new discoveries were made. Some namely the immunocytoma and immunoblastic lymphoma. These lymphoma-entities of the non-Hodgkin-group are in the majority of cases neoplastic analogues of transformed B-lymphocytes. Clinico-pathologic correlations and the enzymecytochemical characterisation of the tumor cells are also described in this paper.

1. In non-Hodgkin-lymphomas with leucaemic form of the course a significant percental decrease of the number of T-lymphocytes and an also significant increase of the number of B-lymphocytes was to be proved. The increase of the B-lymphocytes concerned among others cells which carry the ME-receptor. 2. In non-Hodgkin-lymphomas with aleucaemic form of the course in decrease of the absolute number of lymphocytes a relative and absolute increase of the subpopulation of lymphocytes carrying the ME-receptor was provable. 3. In the course control of 7 patients with non-Hodgkin-lymphoma under polychemotherapy in 5 cases a discrepancy between the number of rosette-forming cells and the total number of lymphocytes appeared. 4. In the monotherapy of patients with CLL in favourable clinical development a percental increase of the T-cells is objectifiable after one year. A similar development was to be found in 3 patients after the first cycle with CVP.

Sera from 50 patients with Hodgkin's disease, 78 patients with non-Hodgkin non-leukemic malignant lymphomas, and 75 patients with different types of solid malignant tumors were investigated for the presence of immune complexes using the (125I) C1q-binding test. All patients were untreated. An increased serum C1q-binding activity was found in 22% of the patients with Hodgkin's disease, 35.9% of the non-Hodgkin lymphoma patients and in 37.3% of the patients with solid tumors. The C1q-binding material detected in the patients' sera had properties similar to those of immune complexes. On sucrose density gradient it sedimented as a 10-30 s material. It contained IgG which were dissociated under acid conditions. Passage through anti-IgG immunoabsorbent removed its C1q-binding properties. A prevalent association was found between the presence of serum immune complexes and disseminated disease stages in all the patient groups included. A similar association was found between the presence of serum immune complexes and general symptoms among the malignant lymphoma patients. The nature of the antigens involved in the complexes remains unknown.

Some direct and indirect arguments are at present in favour of the B-lymphocyte origin of the Reed-Sternberg (R.S.) cell. Immunoperoxidase methods applied to paraffin sections permit to identify immunoglobulin components in their cytoplasm, but these results are not suffisant to prove that the R.S. cell synthesizes immunoglobulins. We have applied immunoelectronmicroscopic methods to a lymph node in a case of Hodgkin's disease. The results permit us to found intracellular immunoglobulins in the R.S. cell and to evoke a probable synthesis of immunoglobulin by free ribosomes, thus agreing the B-lymphocyte nature hypothesis of the R.S. cell.
