Insulins of differing species, together with chemically modified insulins, were used in cross-reactivity experiments employing selected antisera raised to ox insulin in the Harley guinea-pig. The immunogen had been administered as a water-in-oil emulsion, using H. pertussis vaccine as adjuvant. Antibody was generated by determinants in the C-terminus of the B chain plus the adjacent N-terminus of the A chain, in the central core of the A chain (A8-A14 region) and in its anti-parallel N-terminus of the B chain. From this antibody pool chemically modified ox insulin selected antibody to unaltered determinants. The immunochemical data were compatible with monomeric ox insulin being immunogenic, the immunogen perhaps being recognized by the immune system in the form of the Molecule-II rather than the Molecule-I of the dimer pair (as originally suggested by X-ray crystallographic data).

Isomaltohexaose flavazole coupled to chicken gamma-globulin (IM6-CGG) induced T cell-dependent anti-alpha(1 leads to 6) dextran-specific IgM and IgG responses in CBA, BALB/c and A strain mice. The IgG responses were of restricted heterogeneity as judged by isoelectric focusing, and belonged mostly to the IgG1 subclass with a minor IgG3 component in the case of BALB/c and CBA mice. All four subclasses of IgG were produced in A strain mice. In contrast, native dextran B 512 induces exclusively T cell-independent IgM responses of the same specificity for all 3 strains. All BALB/c mice immunized with different doses of IM6-CGG either in Freund's adjuvant or with Al(OH)3 plus Bordetella pertussis showed the same spectrotypes by isoelectric focusing. Sera obtained at different times after immunization of BALB/c mice failed to show spectrotype variations. Late, but not early, bleedings from CBA mice showed a tendency towards more uniform isoelectric focusing patterns.

Inbred Hooded Lister rats were immunized with egg albumin with B. pertussis vaccine used as an adjuvant. The serum levels of total IgE and IgE antibody (egg albumin specific) were determined by radioimmunoassay techniques before and after immunization. The basic level of total IgE in serum was 560 +/- 110 ng/ml. After immunization a maximal peak at day 11 of 1940 +/- 160 ng/ml was registered. Anti-egg albumin IgE antibody showed a maximum around day 13 of 75 +/- 11 units/ml. Pleural mast cells were isolated on Ficoll between day 14 and 20 after immunization. A significant negative correlation between the basic total IgE level and histamine release by antigen (egg albumin) was found and also a significant positive correlation of specific IgE antibody (determined at day 11) and histamine release. The correlation between IgE level and histamine release was slightly improved if instead the ratio of specific IgE antibody over total IgE was used.

PVG/c rats, infected 3 days previously with 10(3) Trypanosoma brucei brucei S.42 organisms failed to develop adjuvant disease in response to an intradermal inoculation of mycobacterial adjuvant. By contrast, similarly infected rats, immunized with heterologous brain and spinal cord in Freund's complete adjuvant with pertussis vaccine as a secondary adjuvant, developed clinical signs of allergic encephalomyelitis (EAE) at least as severe as those in uninfected rats. Delayed hypersensitivity reactions to PPD were depressed in trypanosome-infected, adjuvant-injected rats, as were the reactions to myelin basic protein in infected rats developing EAE. There appeared to be no cross-reactivity between trypanosomal antigen and myelin basic protein which could account for the lack of suppression of EAE. It is suggested that the different extent to which autoimmunity is involved in these two experimental allergic diseases may account for the differential suppressive activity of trypanosome infections upon them.

(Responder [R] X nonresponder [NR])F1 mice give indistinguishable primary in vitro plaque-forming cell (PFC) responses to either R or NR parental macrophages (Mphi) pulsed with the Ir-gene controlled antigen L-glutamic acid60-L-alanine30-L-tyrosine10 (GAT). However, such (R X NR)F1 mice, if primed to GAT, retained in vitro responsiveness to GAT-R-Mphi, but no longer responded to GAT-NR-Mphi. This suggested (a) a possible Mphi-related locus for Ir gene activity in this model, and (b) the occurrence of active suppression after priming with GAT leading to a selective loss of the usual primary responsiveness of (R X NR)F1 mice to GAT-NR-Mphi. This latter interpretation was tested in the current study. [Responder C57BL/6 (H-2b) X nonresponder DBA/1 (H-2q)]F1 mice were primed with 100 microgram GAT in pertussis adjuvant. 4-8 wk later, spleen cells from such mice were tested alone or mixed with normal unprimed F1 spleen cells for PFC responses to GAT-R-Mphi and GAT-NR-Mphi. The primed cells failed to respond to GAT-NR-Mphi, and moreover, actively suppressed the normal response of unprimed F1 cells to GAT-NR-Mphi. If the primed spleen cell donor had been treated with 5 mg/kg cyclophosphamide 3 days before priming or with 5-10 microliter/day of an antiserum to the I-Jb subregion [B10.A(5R) anti B10.A(3R)] during the first 4 days postpriming (both procedures known to inhibit suppressor T-cell activity), cells from such mice responded in secondary culture to both GAT-R-Mphi and also GAT-NR-MPhi. In addition, such spleen cells no longer were capable of suppressing normal F1 cells in response to GAT-NR-Mphi. Similar data were obtained using [CBA (H-2k) X DBA/1 (H-2q)]F1. Further, it was shown that (a) primary responsiveness to GAT-NR-Mphi was not an artifact of in vitro Mphi pulsing, because in vivo GAT-pulsed Mphi showed the same activity and (b) the secondary restriction for Mphi-antigen presentation was controlled by H-2 linked genes. These data suggest an important role for suppressor T cells in H-2 restricted secondary PFC responses, and also provide additional support for the hypothesis that Ir-gene controlled differences in Mphi antigen presentation are related to both suppressor cell generation and overall responsiveness in the GAT model.

The postnatal development of resistance against infection was monitored by the treatment of juvenile mice with a virulent strain of Listeria monocytogenes. It could be shown that until day 10 after birth, young mice succumbed to an infection with even minimal doses of bacteria. Between day 15 and 30, the resistance against infection gradually increases until the rather constant level of grown-up animals is reached (Fig. 1). Juvenile mice that survive the primary infection are able to build up a state of immunity, which is rather similar to that of grown-up mice (Fig 3). Immunity against L. monocytogenes is mainly expressed by a functionally active T-cell system; the maturity of these cells in 15 days old mice could be demonstrated by the transfer of cells to "nude"-mice, which lack a thymus (Fig. 4). A significant increase of the non-specific resistance can be achieved even in 10 days old mice by the injection of adjuvants like pertussis organisms or endotoxin of Salmonella typhi some days before infection (Fig. 5, Fig. 6). Our findings suggest that a deficiency of functionally active macrophages is responsible for the insufficient resistance against infection with L. monocytogenes in young mice.

The expanded programme on immunization feasibility studies is currently running into its second year of operations. The objectives of the study are to test the possibility of increased coverage using both fixed centre and mobile field teams for the vaccination of children under the age of 2 years against measles, poliomyelitis, diphtheria, pertussis, tuberculosis and smallpox and also to test the immunological response to two doses of pertussis and two doses of oral polio. Reports so far indicate some success in the areas of training and manpower development as well as the development of the cold chain system which is considered to be the most important requirement for an efficient, expanded immunization programme. It goes without saying that the progress of the study has been marked by some technical, social and administrative constraints.

For major diseases for which control measures are inadequate, research is an inexpensive approach on the basis of cost per infected person per year. Priorities among the infectious diseases affecting the 3 billion people in the less developed world have been based on prevalence, morbidity, mortality and feasibility of control. With these priorities in mind, a program of selective primary health care is compared with other approaches and suggested as the most cost-effective form of medical intervention in the least developed countries. A flexible program delivered by either fixed or mobile units might include measles and diptheria-pertussis-tetanus vaccination, treatment for febrile malaria and oral rehydration for diarrhea in children, and tetanus toxoid and encouragement of breast feeding in mothers. Other interventions might be added on the basis of regional needs and new developments. Aiming services at the most important diseases is the only rational approach to absolute proverty and unsanitary conditions. The goal is to help the greatest number of people in the cost effective method possible.

The humoral immune response to tetanus toxoid is evaluated by passive haemagglutination test in mice receiving low diet immediately after weaning during 15 and 30 days. The results show that the more deficient mice give the best antitoxin titers but after the challenge the antibody immune response become proportional to the protein restriction. In other respects and antitoxin titers are higher in 30 days restricted mice than in 15 days deficient ones. The effect of Bordetella pertussis adjuvant on the immune response of protein deficient mice seems nul. These results are discussed.

1. Epinephrine-induced hyperglycemia was attenuated by the treatment of rats with pertussis vaccine, but this attenuation was abolished when endogenous insulin was suppressed by streptozotocin or anti-insulin serum. It was concluded that epinephrine-induced hyperglycemia was counterbalanced by the hypoglycemic action of insulin, the secretion of which was markedly potentiated in pertussis-sensitized rats. 2. Without epinephrine, no hypoglycemia developed in pertussis-sensitized rats despite the higher blood level of insulin. Tracer experiments with [14C,3H] glucose or [14C]bicarbaonate showed that, in pertussis-sensitized rats, more glucose was liberated into the blood from hepatic gluconeogenesis at the expense of hepatic glycogenesis, thereby accelerating the turnover of blood glucose. 3. Since this activation of hepatic glucose production was reduced by propranolol, a beta-adrenergic blocking agent, it is very likely that adrenergic beta-stimulation is, at least partly, responsible for the metabolic alterations observed in pertussis-sensitized rats.
