The effects of prostaglandin E1, E2, F2alpha (PGE2 PGF2alpha), isoproterenol, epinephrine, norepinephrine, salbutamol, practolol, atropine, aminophylline, and corticosterone on the hypersensitivity to anaphylaxis, histamine, and serotonin in Bordetella pertussis-treated mice and propranolol-treated mice were investigated. Female HLA-SW (ICR) mice, 27-29 gm, were injected with pertussis vaccine intravenously 4 days before challenge with antigen, histamine, or serotonin. Alternatively, instead of pertussis vaccine, propranolol was injected intraperitoneally 45 min before histamine challenge. Test drugs were administered intraperitoneally 15 min before challenge. PGE1 and PGE2 at a narrow range of between 10 and 100 mug and epinephrine at 100 mug protected both pertussis- and propranolol-treated mice. Isoproterenol (25 mug) and aminophilline (800 mug) protected beta-blocked mice, but did not protect pertussis-treated mice even with very high doses (1,000 and 3,2000 mug, respectively), although salbutamol (500 mug) did. PGF2alpha, norepinephrine, and atropine were not protective at all. Practolol, a beta 1-blocker, given intraperitoneally 30 min before histamine neither sensitized normal mice nor changed the effect of isoproterenol or salbutamol in pertussis-treated mice. Corticosterone 10 mg/kg reduced the number of deaths from histamine in beta-blocked mice, but not in pertussis-treated mice. The protective effect is discussed in connection with probable effects of the drugs on intracellular cyclic adenosine monophosphate (cAMP) levels.

An epidemic of pertussis occurred among hospital staff caring for paediatric patients. Eight physicians and five nurses were affected. Pertussis developed in six newborn infants exposed to infected hospital staff in the nursery. Erythromycin prophylaxis was used to control the epidemic. Clinical pertussis developed in five adults infected with Bordetella pertussis before erythromycin was used, whereas symptoms developed in only one of the eight adults who became infected after erythromycin prophylaxis was started. Pertussis vaccine was given to adult volunteers in the hospital, and in 77% of two hundred and eighty-six vaccinees there was a fourfold rise in pertussis agglutinins. Local reactions were common, and in two vaccinees generalised rashes developed. One of these required treatment with corticosteroids. The risk of pertussis occurring in adults providing medical care for children should be recognised, and employees with symptoms should be removed from the hospital environment.

Following the intravenous injection of streptozotocin into rats, postprandial hyperglycaemia was sustained from 24 hours over a subsequent period of some weeks and the rats were glucose intolerant. When streptozotocin was similarly injected into pertussis-sensitized or hydrocortisone treated rats, the postprandial hyperglycaemia observed at 24 hours did not persist, but showed a progressive decline until near normoglycaemia was obtained a week later. These animals manifested normal glucose tolerance one week after streptozotocin. Thus, a spontaneous recovery from streptozotocin-induced diabetes occurred under these conditions. This spontaneous recovery from diabetes was associated with hyperinsulinaemia in the fed state.

The defect in Leiner's disease, which presents in early infancy with extensive dermatitis, diarrhoea, and failure to thrive, has been attributed to a defect of the fifth component of complement (C5). We report 2 brothers with extensive dermatitis and dysgammaglobulinaemia. Both died. The older showed symptoms of Leiner's disease: C5 tests were not performed. The younger had extensive dermatitis and was found to have the C5 defect. He developed normally, but died suddenly with pertussis. We postulate that the C5 defect is not the sole cause of Leiner's disease as has been suggested, but that hypogammaglobulinaemia or other lymphoid deficiency is also required for its expression.

The cardinal immunologic changes in sarcoidosis consist of depression of delayed-type hypersensitivity, hyperreactive circulating antibody responses and the Kveim-Siltzbach skin test phenomenon. Depression of delayed-type hypersensitivity is demonstrated by skin tests using tuberculin, mumps, pertussis, trichophytin, oidiomycin, dinitrochlorobenzene and Californian keyhole limpet hemocyanin. The cultured lymphocytes from patients with depression of delayed-type hypersensitivity react poorly to phytohemagglutinin, and there is a close correlation between anergy of lymphocytes in culture and by cutaneous anergy. In vivo cutaneous anergy mirrors in vitro cellular hyporeactivity. Other technics used to expose immunologic defects in peripheral lymphocytes of patients with sarcoidosis include tests of T and B cell function, rosetie formation and migration inhibition. Whereas there is cutaneous anergy and impaired cellular immunity in patients with sarcoidosis, the reverse holds for circulating factors. There are increased circulating immunoglobulin levels, increased circulating antibody levels to Epstein-Barr, herpes simplex, rubella, measles and parainfluenza viruses, increase antibody response to mismatched blood and occasional false-positive Wassermann reactions, but there is no increase in circulating autoan tibodies. There is no evidence that patients with sarcoidosis belong predominantly to any particular histocompatibility locus. Worldwide figures for the Kveim-Siltzbach skin test are presented. They provide evidence of its specificity in various international series. The causes of nonspecific reactions are discussed.

The author presents materials concerning the study of the toxic properties of 12 pertussis cultures used in the USSR for the production of vaccines. As a result of studying the toxic properties of the microbes in the test of the change of the weight of mice, and in experiments of testing the anaphylactogenic and histamine-sensitizing activities it was revealed that the strains of pertussis microbes differed by the quantitative content in them of the thermolabile toxin, endotoxin, lymphocytosis-stimulating and histamine-sensitizing factors; therefore, the period of keeping the pertussis suspensions for 1.5 months from the moment of detoxication proved to be inadequate for some of the strains. Since the toxic properties of the strains failed to correlate with their protective activity, in recommendation of pertussis strains for the production of pertussis vaccine preference should be given to the strains with lesser toxic properties.

The effects of exogenous nucleotides on the histamine hypersensitivity of pharmacologically beta-blocked mice were investigated. Female HLA-SW (ICR) mice, 27-29 gm, were injected intraperitoneally with 20 to 100 mug of propranolol 45 min before intraperitoneal challenge with 1 mg histamine. These animals had a mortality which averaged approximately 80%. At various time intervals before histamine, doses of from 0.5 to 12 mumoles of nucleotides were administered intravenously. Noncyclic nucleotides, adenosine, adenosine 5'-monophosphate (AMP), and guanosine 5'-monophosphate (GMP) showed clear, dose-response protection against histamine death of propranolol-treated mice when they were given 45 to 90 min before histamine. Cyclic AMP showed significant protection only when it was given at a dose of 8 mumoles 45 to 90 min before histamine, and lower or higher doses gave equivocal or no protection. Cyclic GMP WAS Not protective at any dose tested. Propranolol treatment also produced enhanced sensitivity to passive systemic anaphylaxis. Mice were passively sensitized by intraperitoneal injection of mouse anti-egg albumin antibody 6 hr before intravenous challenge with 0.5 mg egg albumin. The mortality from anaphylaxis in the group treated with 20 mug propranolol 45 min before antigen challenge increased to 83%, while that of the group not given propranolol was only 10%. Nucleotides were given intravenously 45 min before antigen challenge. The nucleotides that protected mice from death due to histamine challenge also protected them from death due to systemic anaphylaxis. These protective nucleotides were the same nucleotides that had been reported previously to be protective against Bordetella pertussis-induced hypersensitivity to histamine and anaphylaxis.

The purified lymphocytosis promoting factor (LPF) from Bordetella pertussis was found to be a potent mitogen for peripheral blood lymphocytes (PBL) from normal adults as well as for cord blood lymphocytes. Proliferation occurred in autologous plasma or fetal calf serum, regardless of previous exposure to pertussis infection or immunization. Only one adult human serum, from a physician constantly working with B. pertussis, inhibited the mitogenic response to LPF and this serum was shown to contain precipitating antibody against LPF. The proliferative effect of LPF was characteristic of a "nonspecific" mitogen and not of antigen stimulation of sensitized cells.LPF, phytohemagglutinin, and concanavalin A were approximately equal in potency although variation occurred depending upon the cell donor. Experiments with lymphocyte subpopulations obtained by rosetting techniques employing sheep erythrocytes, mouse erythrocytes, and sheep erythrocytes coated with antibody and complement suggested the requirement of a multicellular system for LPF mitogencity.PBL from most patients with chronic lymphatic leukemia and lymphosarcoma cell leukemia were even less responsive to LPF than to phytohemagglutinin, whereas PBL from patients with lymphosarcoma usually responded to both mitogens. It can be inferred from the results of experiments with both normal and leukemic cells that LPF, which is a murine thymus-derived (T)-cell mitogen, is also a T-cell mitogen for human PBL. The exact cell requirement and mode of action, however, are as yet unknown.

Mice exposed to a sublethal dose of X-rays were immunized with alum-precipitated DNP-KLH (dinitrophenyl-keyhole limpet haemocyanin) and B. pertussis either before or after irradiation. The primary anti-DNP antibody response was evaluated during 8 weeks after immunization by the equilibrium dialysis technique using ammonium sulphate- precipitated serum globulins and the ligand 3H-labelled xi-DNP-L-Lysine. The serum concentrations of antibody sites in mice immunized 1-5 days before or 2 h-8 weeks after 450 rad were below the values in unirradiated controls at all bleeding times. Antibody affinity, however, was found to be up to 20 fold higher in irradiated mice than in control mice when antigen was injected before, or 3-8 weeks after, irradiation. Spleen cells from mice exposed to 450 rad 1-9 weeks before killing were stimulated in vitro with PHA, ConA, or LPS. Recovery profiles of mitotic responsiveness suggest that enhancement of antibody affinity in irradiated mice could result from relative lack of suppressor T Cells.

The development of a specimen collection and transport medium outfit for the rapid laboratory diagnosis of whoping cough is described. The transport medium consisted of a semisolid agar containing charcoal, cephalexin, and defibrinated horse blood. It was also found to be an excellent enrichment medium for the selective isolation of Bordetella pertussis and B. parapertussis from scantily populated specimens. The investigation of 3,237 specimens that yielded 1,419 positive isolates of Bordetella, including 86 B. parapertussis, during a 20-month period is presented. A total of 3,076 specimens were processed in the laboratory by using the enrichment medium in addition to the routine procedure. Of these specimens, 757 were submitted in our medium, from which 137 (18%) were positive. Of the 567 specimens received in Amies transport medium, 290 (51%) positive cultures were obtained by the enrichment method only and not by primary culture.
