    Notes: Studies of 521 sera from the Icelandic cousin marriage project were made to assess the incidence of various anti-tissue antibodies and the levels of immunoglobulins, as these were considered to be useful markers of the humoral immune response. Comparisons were made between these parameters and the HLA-A and B antigens, the blood groups, the immunoglobulin allotypes (Gm, Km and Am), the properdin factor (Bf), and other markers.These investigations offered another approach to the study of the sites of action of immune response genes in man. Because the immune response may be expected to differ for each individual and depend at least in part, on the degree of exposure to different antigens, no absolute correlation was expected. There was, however, a marked association between certain IgG anti-tissue antibodies and HLA antigens. This was most marked for HLA-A10, B18 and B27, but not for HLA-A1 or B8.The comparison of immunoglobulin levels with HLA antigens, was less striking, although HLA-A2 appeared to be associated with low levels of IgE. There were also some associations between immunoglobulin levels and ABO blood groups.

    Notes: Approximately 25% of infants tested released 〉9% of their blood basophil histamine content in the presence of cow's milk proteins, indicating a degree or level of latent anaphylactic sensitivity to these allergens. Approximately 10% of infants show a considerably higher level of sensitivity (14-63% histamine release). These findings fulfil an essential tenet of the modified anaphylactic hypothesis for cot-death.

    Notes: Basophil leucocyte-bound IgE has been investigated in patients with chronic urticaria by the method of reversed anaphylaxis. In this reaction basophil-bound IgE behaves as an antigen, the amount present being inversely proportional to the concentration of anti-IgE producing maximum histamine release. Dose-response curves in which histamine release was plotted against the concentration of anti-IgE failed to reveal any substantial difference in the optimum concentration of anti-IgE for maximum release from basophils of urticarial subjects compared with control subjects, thus suggesting there is no quantitative abnormality of basophil bound IgE in chronic urticaria. However, the magnitude of maximum histamine release by anti-IgE from basophils of urticarial subjects was reduced compared with controls and this was not related to serum IgE concentrations since the mean serum IgE concentration was slightly higher in the urticaria group. Studies of spontaneous and compound 48/80-evoked histamine release in the two groups did not reveal any differences in stability of histamine stores or in the biochemical histamine release mechanism over a wide range of concentrations of 48/80. These results raise the possibility of a qualitative abnormality of basophil bound IgE in chronic urticaria.

    Notes: Allergy to cows' milk is an important and frequent cause of cows' milk protein-intolerance in infants. Many infants within days of birth are fed cows' milk or cows' milk-based formula feeds. It is thought desirable to have a test available that would indicate the allergenic potency per os of milk formulae and of milk substitutes intended for infant feeding.Such a test, based on the finding that guinea-pigs drinking cows' milk become anaphylactically sensitized to milk proteins, is described. After drinking pasteurized milk for only 4 days, 88% of guinea-pigs were susceptible to fatal anaphylaxis on intravenous challenge on the 22nd day; drinking milk for 8 days resulted in 100% of guinea-pigs becoming sensitive to fatal anaphylaxis. Following milk drinking for 7 days, a subsequent interval of 7 days was required before anaphylactic sensitivity could be shown in 100% of animals. With this information the effect of heat on the per os allergenic potency of cow's milk could be examined; likewise the allergenic potency of supposedly hypo-allergenic infant feed formulations.Pregestimil induced no anaphylactic sensitivity even after 37 days of drinking, and no anaphylactic antibodies, detectable by PCA, were formed to the milk proteins β-lactoglobulin and casein. In contrast, AL110 likewise drunk by guinea-pigs for 37 days resulted in 90% fatal anaphylactic reactions in animals challenged with the same product. Anaphylactic antibodies were found to casein but not to β lactoglobulin.Comminuted Chicken and Prosobee (a soya milk), two alternative ‘hypo-allergenic’ cows' milk substitutes, rendered approximately 50% guinea-pigs anaphylactically sensitive to the product fed, but neither product stimulated cross-reactive anaphylactic antibodies to either casein or β-lactoglobulin as tested by PCA.There is some indirect evidence that results of the guinea-pig test are relevant to responses in infants with cows' milk protein intolerance.

    Notes: The quantitative measurement of the IgE and IgG subclass levels in the sera of 29 patients with atopic dermatitis has revealed significantly elevated levels of IgE and IgG4 in a relatively high proportion of patients with this condition compared to non-atopic patients with warts and to a group of normal volunteers studied previously. The possible significance of these observations is discussed in relation to current evidence suggesting the involvement of IgG4 in certain immediate-type hypersensitivity disorders.

    Notes: Summary White Leghorn line C chicks were surgically bursectomised (Bx) in ovo to eliminate antibody production. After inoculation with infectious bronchitis virus (IBV) at 14 days after hatching, Bx chicks experienced a more severe and longer lasting infection than intact chicks. The severity and duration of clinical infection in the Bx chicks resembled that previously observed in the highly susceptible line 15 I chicks, however no increase in mortality was observed, in contrast to the high levels of mortality recorded in IBV-inoculated line 15 I chicks. After secondary challenge the degree of damage to the ciliated epithelium of the trachea was greater in the Bx chicks than in the intact chicks. The results indicate that, although antibodies play an important role in recovery from IBV infection, other immunological factor(s) may also be involved.
