    Notes: The morphological changes in blood basophils, from patients with bronchial asthma, were studied in vitro during immunological reactions, with particular reference to interaction with anti-IgE. Anti-human IgE results in an absolute reduction in basophil numbers in buffy coat preparations as well as basophil cytoplasmic degranulation. An increase in the numbers of pear-shaped (A-form) basophils is also observed. Sodium cromoglycate impairs all these anti-IgE induced basophil changes, providing further insight into the mechanism of action of this compound in bronchial asthma.

    Notes: Vesicular exudate, produced by the application of cantharides plaster over normal skin and sites of intradermal allergen injection, was examined for the presence of basophils and eosinophils in normal subjects and patients with bronchial asthma. In comparison with the normals, the asthmatic group demonstrated a high rate of basophil appearance in vesicular fluid derived from areas of untreated skin. Basophil appearance was even more prominent in vesicular fluid from skin injected intradermally with various allergens. Modest numbers of basophils appeared at skin sites injected with house dust, but relatively large numbers appeared in areas injected with Candida, ragweed or tuberculin extracts. Patients with severe, intractable asthma frequently demonstrated large numbers of basophils in vesicular exudates. Intradermal injections of anti-IgE caused the greatest number of basophils to appear in the vesicular fluid, The numbers of eosinophils migrating into such vesicular lesions were not statistically significant though their numbers were proportional to those of the basophils. A significant correlation was shown to exist between both basophil and eosinophil blood counts and the numbers of these cells appearing in cutaneous vesicular fluid.This study demonstrates that basophil leukocytes, together with eosinophils, migrate from blood into extravascular tissues at sites of allergic reaction—especially reaginic hypersensitivity. The skin vesicle technique described is simpler than the skin window technique and may be of use in detection of allergens and evaluation of allergic disease states.

    Notes: The relationship of the basophils in the peripheral blood of patients with bronchial asthma to their allergic reactions has been studied. The basophils were stained and counted using our improved method of Kovács. The results showed that the basophils increased in the pre-attack stage and a count of 65/mm3 or more made it possible to predict a forthcoming attack. Among the patients on prolonged treatment, the basophils which were over this level during repeated asthmatic attacks decreased during the attack-free stage, reflecting the effects of therapy. It was also found that the basophils were increased in those patients with allergic asthma whose sera gave positive Prausnitz-Küstner reactions. This study suggests a significant relationship of peripheral blood basophils with the allergic reaction.

    Notes: Immunolatex particles were used as markers for IgE receptors on basophils using electron-microscope scanning. These particles appeared to bind specifically to basophils. Basophils from atopic asthma patients showed greater binding to latex particles than those from intractable asthma patients or healthy subjects. Cap and patch formations on IgE receptors were frequently found in basophils of atopic asthmatics, and cap formation was observed only on basophils that were pear-shaped. The redistribution of IgE receptors, such as that by cap formation, may be a significant triggering mechanism for basophil activation.The latex density on basophils pre-treated with anti-human IgG was much greater in intractable asthmatics than in atopic asthmatics or healthy subjects, and almost all basophils with increased immunolatex particles were pear-shaped, suggesting the presence of some IgG receptors on the surface, and such receptors may play an important role in intractable asthma.

    Notes: A total of 108 samples of sputum obtained from twenty patients with bronchial asthma were examined for appearance of basophils and eosinophils. Both cell types are present in sputum during an asthmatic attack and disappear at the conclusion of the attack. Their presence correlates with the severity of the disease. It has previously been demonstrated that the blood basophils count falls during attacks of bronchial asthma, and the present study suggests that basophils move from the blood stream into bronchial tissue during the acute phase of an asthmatic attack.

    Notes: Changes of basophil reactivity to housedust extract and anti-IgE during immunotherapy was examined in thirteen patients with bronchial asthma sensitive to housedust. (i) A significant decrease in the morphological reactivity of basophils to housedust extract was observed 6 months after the beginning of immunotherapy with the antigen, and a significant decrease after 12 and 18 months’ therapy, accompanied with the decrease of histamine release from the cells. The percent reactive basophils to the antigen decreased from 59.2 ± 2.9% before the therapy to 40.0 ± 1.8% after 18 months’immunotherapy. (ii) A decrease in the morphological reactivity of basophils to anti-IgE was also shown during immunotherapy. The basophil reactivity to anti-IgE decreased significantly at the late stage (18 months) of immunotherapy. (iii) A significant reduction of specific IgE antibody to housedust was observed 12 and 18 months after the beginning of immunotherapy. It was suggested from these results that immunotherapy causes some changes on the surface of basophils and decreased reactivity of the cells, and that a decrease of reactive basophils to anti-IgE in the process of immunotherapy might be due to a decrease in number of IgE receptors essentially or functionally.

    Notes: Summary Eighty-four previously treated adult patients with acute leukemia and malignant lymphoma were treated with (2″R)-4′-O-tetrahydropyranyladriamycin (THP). THP (10–55 mg/m2) was administered by i.v. bolus injection daily for acute leukemia, and according to three different schedules for malignant lymphoma: daily, weekly or once every 3–4 weeks. Complete and partial remission (CR and PR) were achieved by 1 (5%) and 3 of 19 patients with acute myelogenous leukemia and by 2 (13%) and 3 of 15 patients with acute lymphoblastic leukemia, respectively. All CRs were in the groups receiving 25 mg/m2 THP daily. CR and PR were achieved by 6 (14%) and 8 of 42 patients with non-Hodgkin lymphoma (NHL) and by 4 (50%) and 2 of 8 patients with Hodgkin's disease (HD), respectively. No particular sensitivity was found among the subtypes of NHL and HD. Response (CR+PR) was noted in 10 (40%) of 25 patients treated every 3–4 weeks, in 1 (17%) of 6 treated weekly, and in 9 (47%) of 19 treated daily. The major side effects were myelosuppression and gastrointestinal toxicities. Alopecia was observed in only 10 (12%) patients. ECG abnormalities were observed in 7 (10%) patients, all of whom had previously been treated with other anthracyclines. No severe cardiotoxicity was observed.

    Notes: Summary The effect of immunotherapy with a protein-bound polysaccharide preparation termed PSK on remission duration and survival of adults with acute nonlymphocytic leukemia (ANLL) was studied in a prospective randomized cooperative trial. After having achieved complete remission and receiving a consolidation therapy, 73 patients were randomized either to maintenance chemotherapy or to maintenance chemotherapy plus immunotherapy with PSK. Ultimately 36 patients in the chemotherapy group and 31 in the chemoimmunotherapy group were evaluable. Six months after the last entry, immunotherapy with PSK showed a borderline beneficial effect on remission duration (P=0.089) and on duration of survival (P=0.062). When the data were analyzed 12, 18, and 24 months after the last entry there were no significant differences in duration of remission and survival between the two groups. However, analysis of the data of patients who had maintained complete remission for more than 270 days revealed that immunotherapy had a suggestive beneficial effect (P=0.105), prolonging the 50% remission period by 418 days (885 vs 467 days). Thus, immunotherapy with PSK seems to be active in the treatment of adult ANLL when used for maintenance therapy in combination with chemotherapy, especially in patients with a good prognosis.

    Notes: Summary Rabbit xenoantiserum was produced against a human leukemia cell line (NALL-1) derived from a patient with acute lymphoblastic leukemia, and IgG was purified. Anti-NALL-1 rabbit IgG was reacted with NCS, an unique membrane-reactive anticancer antibiotic, in the presence of water-soluble carbodiimide. The resulting mixture was concentrated and chromatographed on a Sephadex G-200 column. The first and second fractions were shown by immunoelectrophoresis and the Ouchterlony double-diffusion method to contain NCS-IgG but not free NCS. The conjugates inhibited the growth of Sarcina lutea, and the growth and 3H-TdR incorporation of NALL-1 cells. A membrane immunofluorescent test with FITC-labeled rabbit anti-NCS and goat anti-rabbit IgG antibodies demonstrated specific localization of NCS-IgG on NALL-1 cell surfaces. These results indicate that IgG-bound NCS retained both NCS and antibody activities, and thus should be useful for cancer therapy.
