Fifty-two cases of non-
Hodgkin
's lymphomas were studied with enzyme histochemical methods. Forty-four cases of these were also investigated for surface markers with immunological techniques, and results of histochemical, routine histological and immunological observations were correlated. Twenty-one of 27 B-cell lymphomas showed prominent ATPase activity, while all 13 T-cell lymphomas, except one case, did not show such activity. Nodular lymphomas, though of B-cell nature, were often negative for ATPase and it remained negative after diffuse evolution in some. Four of 7 A1Pase positive lymphomas were of B-cell origin. Dot-like localized AcPase and beta-glucuronidase activity characterized T-cell lymphomas while 5 T-cell PDL, including lymphoblastic type with double markers, showed localized esterase activity. Enzyme histochemical characteristics of lymphomas were fairly honest reflection of those of various functional units in the normal lymph nodes. Enzyme histochemical methods appeared to be a useful tool for the study of lymphomas.

The 5-year experiences of a center for pediatric oncology in a children's university hospital are reported. Currently (1-1-1975) 60 of 135 treated leukemic and 88 of 152 treated tumor patients are living. 1974, there were in the average 34 ambulatory complete blood counts per week, and in addition 263 bone marrow and 196 ambulatory lumbar punctures per year. The standardized routine of an outpatient visit is described. Advice for parents and family physicians are given. A standardized diagnostic approach for M.
Hodgkin
as a prototype is proposed, and a standardized therapy for Wilms' tumor. Of 24 thus treated children with Wilms' tumor 16 ("67 p.c.") survive, included 7 of 15 ("47 p.c.") with metastasized disease (observation time 21-71 months). Current treatment of 49 children with acute lymphoblastic leukemia resulted in continuous complete remission of 22 patients ("45 p.c.") (observation time 1-4 years), but 6 dead in complete remission due to infection. The need for specialized treatment centers with skilled persons is emphasized.

A new technique is described whereby viable infiltrating cells can be freed from skin biopsy specimens. The specimens are incubated with collagenase and then mechanically disaggregated. The liberated cells are still suitable for immunological and morphological study. Using this method, the nature of the dermal infiltrate in patients with skin reticuloses was compared with that in lichen planus. A predominance of T cells was found in mycosis fungoides, the Sezary syndrome, and lichen planus, and of B cells in non-
Hodgkin
lymphomas.

From 1961 to 1969 426 patients (208 with
Hodgkin's disease
and 218 with non-Hodgkin's lymphoma) underwent endolympatic radiotherapy with Lipiodol 131I at the National Cancer Institute of Milano. For this study, only those patients with stage I, II, or III disease (with or without systemic symptoms), who were not previously treated, and who had a complete follow-up were reviewed. It appears that while in the cases where there is lymphographic evidence of involved lymph nodes, endolymphatic radiotherapy is not of value, in the cases with apparently negative lymphography, endolymphatic radiotherapy can reduce the incidence of relapse in the inguino-retroperitoneal nodes to a statistically significant degree.

Patients with
Hodgkin's disease
often manifest impairment of cell-mediated immune responses in both in vivo and in vitro tests, as well as a markedly decreased percentage of E rosette-forming (T) lymphocytes in the peripheral blood. This report describes the inhibition of E-rosette formation by normal peripheral blood lymphocytes after incubation with extracts prepared from the spleens of patients with
Hodgkin's disease
. Such extracts also depressed E-rosette formation by the peripheral blood lymphocytes of patients with
Hodgkin's disease
after those cells had been restored to normal function by prior incubation in foetal calf serum. Similarly prepared extracts from the spleens of normal donors had no immunodepressive effect. The E-rosette inhibitory substance in the
Hodgkin's disease
spleen extracts was found to be a complex containing beta-lipoprotein, C-reactive protein, and C1q.

A neoplastic cell line (designated HuT11) has been established in continuous culture from an involved lymph node of a patient with Stage IIA
Hodgkin's disease
of the mixed cellularity type. The HuT11 line has been morphologically heterogeneous, consisting of mononucleate lymphoid-like cells, polygonal epithelioid cells, and mono-, bi-, and multinucleate giant cells. Four clones initiated from isolated binucleate giant cells of the HuT11 line also have been successfully established as continuous cell lines. The cloned lines have been morphologically distinct and more homogeneous, although typical giant cells have consistently appeared throughout the long-term culture of each. The HuT11 lines have grown as monolayers in McCoy's Medium 5A supplemented with 10% fetal calf serum, with generation times of 12 to 14 hr and high saturation densities. Cytogenetic studies showed that early and later passages of HuT11 cells were aneuploid, and all cell lines were successfully heterotransplanted in the hamster cheek pouch. Repeated indirect immunofluorescence examinations have shown each cell line to be negative for Epstein-Barr virus nuclear antigen. Indirect immunofluorescence tests in which monospecific immunoglobulins were used revealed positive membrane reactions for the gamma (heavy)-chain and kappa (light)-chain of human immunoglobulin G in approximately 20% of viable cells in each line; however, direct immunofluorescence with anti-human immunoglobulin G F(ab')2 reagent failed to confirm these reactions. Rosette tests for B- and T-lymphocyte and macrophage membrane receptors yielded negative results. All cell lines were strongly phagocytic for latex particles and neutral red dye. Cytochemical stains of the monolayers revealed abundant esterase, fluoride-resistant nonspecific esterase, acid phosphatase, and leucine aminopeptidase activities, while lysozyme assays were negative. Although some properties of the HuT11 lines have suggested a macrophage derivation, an undifferentiated lymphoid cell origin of the
Hodgkin
's neoplastic cell remains a possibility.

A computer model of a neocortical pyramidal cell has been constructed using ideas similar to those used for hippocampal pyramidal cells. This model has been applied to the study of (a) repetitive firing, and (b) the paroxysmal depolarizing shift (PDS), an important intracellular event during seizures. Although calcium spikes have not been demonstrated directly in neocortical cells, we have postulated (by analogy with hippocampal pyramidal cells) a dendritic calcium conductance and a 'slow potassium' conductance modulated by intracellular calcium ion. With these dendritic ionic conductances, the model is able to reproduce the following experimental features of neocortical pyramidal cells: the afterdepolarization and succeeding afterhyperpolarization after an antidromic spike, and the f-I (firing rate-injected current) curve. Some of the differences between 'fast' and 'slow' pyramidal tract neurons (PTNs) -- narrower spikes and a steeper f-I curve in the fast PTNs -- may be explained by differences in
Hodgkin
-Huxley potassium kinetics between the two kinds of cell. The same model which faithfully reproduces repetitive firing behavior also reproduces (given appropriate synaptic inputs) the following intracellular events recording during epileptic seizures: (a) a burst of action potentials superimposed on and followed by a PDS, and (b) rapid repetitive firing succeeded by an IPSP. Thus, a single set of parameters can reporduce both normal physiological behavior and 'epileptic' behavior: the particular behavior seen depending on how the cell is stimulated. This overall result is the same as for our model of the CA1 hippocampal cell. It suggests that certain acutely acting epileptogenic agents, e.g. penicillin, may act by increasing synaptic input (perhaps both excitatory and inhibitory) to pyramidal cells, rather than by altering their membrane properties. As in our CA1 hippocampal cell model, bursting seems to be a phenomenon generated by the apical dendrite.

The CT appearance of normal retroperitoneal lymph nodes has been described. In many instances the structures are too small to be identified. other retroperitoneal structures, such as collapsed bowel loops, vessels, and other perirenal structures, may simulate the presence of nodes. CT is of great benefit in disease with bulky tumors, such as non-Hodgkin's lymphoma, testicular tumors, etc. Its usefulness is much more limited in disease that may have extensive nodal involvement but no significant enlargement of the nodes. The accuracy of CT scanning in
Hodgkin's disease
and in many instances of genitourinary tumors is questioned, and we submit that further studies are needed to establish the reliability of this mode of examination.

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.

Two cases of disseminated atypical tuberculosis are presented in which the infection anteceded by over four years the development of acute granulocytic leukemia on one and
Hodgkin's Disease
in the other patient. The presence of disseminated atypical mycobacteriosis in the absence of a clearcut underlying illness suggests a "preneoplastic state." It should alert the clinician to the possibility of a neoplastic disorder which may not become clinically manifest for several years.
