Insulin binding to erythrocytes was studied in diabetic patients. Insulin binding was lower in untreated diabetics and diabetic patients treated with diet or insulin than in normal subjects. Binding variation was mainly due to decreased binding site concentration in untreated and insulin-treated patients, and to lowered insulin binding site affinity in diet-treated patients. Several patients treated with hypoglycemic agents showed higher insulin binding due to increased binding site concentration. Insulin binding to erythrocytes may not always reflect the insulin binding status of insulin sensitive tissues.

The addition of L-glutamate resulted in increased cyclic AMP levels in slices from the quarter of cortex with the iron-induced focus. The levels lowered in slices from the quarter of cortex most remote from the focus. Thus L-glutamate showed stimulatory and inhibitory effects on the accumulation of cyclic AMP.

Blebs formed by treatment with cytochalasin B (CB) of the non-capped areas of cells having a cap were isolated and used as the plasma membranes from non-capped areas (ConA-CB-bleb fraction). This bleb fraction was compared with a bleb fraction prepared from cells without ConA-treatment (CB-bleb fraction). Cytochemical analysis of ConA-CB-bleb fraction revealed a decreased in conA binding sites (ConA-BS) compared to the CB-bleb fraction. SDS polyacrylamide slab gel electrophoresis also revealed a decrease in the major components of ConA-BS of the ConA-CB-bleb fraction. The minor components of ConA-BS showed no distinct quantitative difference between the ConA-CB-bleb and CB-bleb fractions. NA+ K+-adenosine triphosphatase (ATPase), 5' nucleotidase (5'ND) and gamma-glutamyl transpeptidase (gamma-GTP) did not show any decrease in activity in the ConA-CB-bleb fraction, but the activity of D+-stimulated phosphatase (K-Pase) was decreased. The findings indicate that there are two types of plasma membrane glycoproteins in EATCs; one includes those participating in cap formation due to ConA, e.g. the major components of ConA-BS and K-Pase, and the other, those not participating in such cap formation, e.g. some minor components of ConA-BS, ATPase, 5'ND and gamma-GTP, which keep their places without moving.

Cervical lymph node biopsy, performed each time, showed the presence of immunoblasts and plasma cells, effaced nodal structure with involvement of the pericapsular tissue, rich vascularity and numerous mitoses, indicative of angio-immunoblastic lymphadenopathy with dysproteinemia (Frizzera, Moran and Rappaport). The existence of hypersensitivity to drugs, in particular, allopurinol in certain patients was emphasized, and induction of immunoblastic lymphadenopathy with various other therapeutic agents was briefly discussed.

In vitro cell-mediated cytoxicity and cytostasis assays were performed to test for the existence of anti-tumor immunity. suppressive activity assayed by cell mixture experiments became apparent with decline of anti-tumor immunity and progressive tumor growth. The cells mediating the suppression were found to be nylon wool column adherent T cells and inhibited T cell dependent cytotoxicity rather than non-T cell dependent cytostasis. In vivo cell transfer experiments demonstrated that intravenous injection of suppressor cells to a host already inoculated with tumor cells mixed with antitumor effector cells resulted in significant enhancement of tumor growth. This inhibition of in vivo neutralization assay be suppressor cells was found in not only allogeneic but also syngeneic tumor system. Splenectomy at the time of tumor resection endowed the host with stronger resistance against subsequent reinoculated tumor than sham-splenectomy did, reflected by prolonged survival times. These results suggest that splenectomy combined with surgical removal of the tumor is a useful treatment of clinical malignancies.

The decay in the responsiveness to Ca++ of the sensitized cells stimulated by antigen in Ca++-free medium in the presence of PS is relatively slow, and maximum release is produced by Ca++ added 1 min after antigen. Histamine release also occurs when Ca++ is added after PS in the absence of antigen to the sensitized cells suspended in Ca++-free medium. Unlike the antigen-induced release, the intensity of this non-antigen-induced release varies depending on both mast-cell and antiserum pools. A heat-labile factor(s), which is different from antigen-specific IgE antibody and is also contained in normal mouse serum, is involved in this reaction. In the antigen-nondependent (PS + Ca++)-induced release, no decay in the responsiveness to Ca++ is observed after PS addition. Both the antigen-induced and non-antigen-induced release are completed fairly rapidly and are dependent of temperature, pH and energy.
