Abstract
Gas chromatography, coupled gas chromatography-mass spectrometry (electron impact mode and chemical ionization with methane as reactant gas), gas chromatography-infrared spectroscopy, and derivatization techniques were used to identity 53 compounds in the interdigital secretion of the red hartebeest, Alcelaphus buselaphus caama. These compounds included alkanes, isoalkanes, alcohols, ketones, carboxylic acids, oxiranes, furanoid linalool oxides, and a large number of branched and unbranched saturated and unsaturated aldehydes. The secretion probably plays a role in demarcation of territories by dominant bulls.

Abstract
The response to the histamine hydrochloride prick skin test was studied in 24 healthy volunteers who received, in random order and at least four days apart, acrivastine (8 mg), terfenadine (120 mg), and placebo. The tests were performed on either side of the back before and at the time of administration (single dose), then every 30 minutes for two hours, and every hour for the following four hours. Evaluation was based on the mean of two measurements of the surface area of the wheal-and-flare reaction accompanied by assessment of topical pruritus. The response to histamine was decreased markedly in the two active treatment groups. Although within one hour of injection, the activity of both antihistamines was consistently greater than that of placebo, the kinetics of action of the two products nevertheless differed; indeed acrivastine was active against flare and wheal earlier (within 30 minutes); terfenadine proved to be more active than acrivastine only on flare and only at the later times (four, five, and six hours). The safety study primarily demonstrated drowsiness in one-fourth of the patients receiving placebo and active treatment.

Abstract
Bronchial hyperresponsiveness (BHR) characterizes asthma and accompanies respiratory infections. Because endotoxin [lipopolysaccharide (LPS)] induces either hyper- or hyporesponsiveness of the guinea pig airways and protects against bronchopulmonary anaphylaxis in sensitized guinea pigs, we compared the effects of the intratracheal administration of Escherichia coli LPS on bronchopulmonary responsiveness to intravenous serotonin or acetylcholine in sensitized and nonsensitized guinea pigs. LPS (1 mg) induced BHR within 1-2 h, with a threefold increase in the bronchial response after serotonin challenge in both groups (n = 6; P < 0.005) and a marked influx of neutrophils into the perivascular and peribronchial connective tissue and the bronchoalveolar lavage fluid. This BHR was not leukocyte dependent, since it was still observed in animals depleted of circulating leukocytes with vinblastine and was not modified by antineutrophil serum, unless platelet counts were < 100,000/mm3. This suggested that LPS-induced BHR involves platelets, and indeed antiplatelet serum, which depleted platelets, or prostacyclin, which inhibited platelets, was effective in suppressing BHR. Neither aspirin, mepyramine, nor the platelet-activating factor antagonist WEB 2170, administered before LPS instillation, prevented BHR, whereas the association of methysergide, mepyramine, and aspirin was effective, without modifying platelet and leukocyte counts. This association has been shown to prevent the release of ATP by ex vivo platelets. Our results suggest that platelets or a platelet-derived product mediates LPS-induced BHR.

Abstract
A double blind multicentre study of seasonal rhinitis (108 patients) has compared Loratadine and Cetirizine. The results of clinical scores are significantly good for both products. Only tolerance is different and in favour of Loratadine, since sleepiness was found in 9.5% of patients treated with Cetirizine, and 3.6% with Loratadine.

Abstract
To determine the relative importance of mites as a cause of allergic sensitivity and asthma on the western Indian Ocean island of Mauritius, we measured specific IgE antibodies to common inhalant allergens in sera from Mauritians claiming to have allergic symptoms and we examined house dust samples for evidence of mites and their allergens. Seventy-two of the 110 sera tested (65%) contained detectable IgE antibody to at least one mite, mould or pollen allergenic extract. By far the most prevalent was antibody to one or both of the common house dust mites, Dermatophagoides pteronyssinus and Dermatophagoides farinae, being present in 67 (61%) of the 110 sera. Allergy to pollens, including the locally prevalent Bermuda grass and sugar cane, was infrequent. Antibody to a limited number of moulds was detected in 22% of the sera tested. Of 81 subjects whose clinical history was known, 60 were asthmatic, and 75% of these asthmatic individuals had IgE antibody to mites. In contrast, only 35% of the subjects with rhinitis without asthma were sensitive to mites. Different mite species, including D. pteronyssinus but not D. farinae, were identified microscopically in samples of local house dust. Mite antigen Der p I but not antigen Der f I was detected with specific monoclonal antibodies in extracts of these dust samples. On the bases of this serological and environmental survey, we conclude that our data support the hypothesis that the house dust mite D. pteronyssinus is the principal cause of allergic sensitivity and asthma in that tropical environment.

Abstract
Two latex (Hevea brasiliensis) raw materials, one from the cytosolic fraction, the other from the total natural latex have been characterised by immunoblotting techniques. The two latex fractions A and B were studied by immunoprints using eight sera from patients who were allergic to latex. They gave different profiles though there were also allergens of common molecular weights (60, 35, 30, 25, 20, 18, 15, and 10 kD). This study confirms the importance of allergic reactions to latex, that may in some patients cause anaphylactic shock.

Abstract
By a revised manufacturing process we aimed to obtain latex surgical gloves without immediate allergenicity, and also to determine a simple physical technique by which to estimate this allergenicity. Five glove samples were evaluated for allergenicity by physical and biochemical methods and by skin tests at the University Allergy Centre. Three groups of allergic patients with documented anaphylaxis to surgical gloves, positive skin tests to latex extract and specific IgE to latex (RAST Pharmacia greater than or equal to class II), volunteered for the study. The protein content, the in vitro allergenic potency of glove supernatants (RAST inhibition) and the skin test results with glove supernatants were lower in washed gloves than in non-washed samples (P less than 0.02 to P less than 0.009). The supplementary effect of glove sterilization at 120 degrees C (for 1 h in saturated steam) was obvious. The protein content became undetectable in four of the five glove supernatants, and skin tests results with sample supernatants were decreased (M +/- SEM = 0.68 +/- 0.29 mm vs 3.06 +/- 0.61 mm with non-sterilized gloves), P less than 0.009 by Wilcoxon test. With the Spearman test there was a significant correlation (P = 0.029) between the mean wheal size, obtained with supernatants (Groups 1 and 2) and electrical conductivity. Skin tests through pieces of gloves randomly distributed and coded were decreased by sterilization: 0.66 +/- 0.25 mm vs 2.86 +/- 0.45 mm, P less than 0.0001. Thus, it is possible to decrease glove allergenicity by washing them after mould forming and then sterilizing with steam. Electrical conductivity may be a simple parameter for revealing allergenicity.

Abstract
The mechanisms of specific immunotherapy are not still established. Among the lot of immunological changes, induced by immunotherapy, the increase of specific IgG 1, and then of IgG 4 antibodies, during the first months is well demonstrated. The skin-tests, the histamine-release and the human basophil degranulation are significantly decreased after incubation of allergen with the serum of desensitized patients. This antigen neutralizing capacity (blocking antibodies) disappeared when IgG 4 were suppressed from the serum by the mean of activated columns linked either with allergen, or protein A or antihuman IgG4 antibodies. Conversely, the total amount of serum blocking activity was found using pure IgG 4. However, the role of IgG 4 antibodies remains a subject of controversy. Since a clear correlation has yet to be established with symptom scores.

Abstract
The interactions between LPS-induced bronchial hyper-reactivity (BHR) and lung inflammation (LI) were investigated. LPS-induced LI was assessed with the augmented alveolo-capillary permeability (ACP) and with the increased migration of neutrophils into the broncho-alveolar lavage fluid. BHR was defined as the increase in the response to a standard dose of serotonin. Mepyramine and the PAF antagonist WEB 2170 blocked LPS-induced increase of ACP, whereas aspirin was inactive. By contrast, neither LPS-induced neutrophil attraction to airways, nor LPS-induced HBR were inhibited by these agents. Our results indicate that LPS-induced edema and BHR are dissociated.

Abstract
Alveolar macrophages from patients with asthma accumulated less cyclic adenosine monophosphate when these macrophages were exposed to isobutyl methylxanthine, salbutamol, or prostaglandin E2, compared to cells from control subjects without asthma, and the degree of the hyporesponsiveness was related to the severity of asthma. In addition, a significantly lower adenylate cyclase activity was observed in crude membrane fractions of macrophages from the group with asthma in the presence of salbutamol and prostaglandin E2. The refractoriness observed in patients with asthma is thus not accounted for by a specific beta-adrenergic desensitization at the adenylate cyclase receptor level but should rather be explained by a cyclic adenosine monophosphate-dependent postreceptor mechanism.

Abstract
Intradermal skin tests (two dilutions) carried out systematically with 5 muscle-relaxant drugs were used to study the cross-reactivity between these drugs in 131 patients who had suffered from anaphylaxis. The skin tests were positive for at least 2 drugs in 65.6% of the cases. We observed a significant concordance (positive-positive or negative-negative skin tests) between pancuronium and vecuronium (p less than 0.01) and a significant correlation between the skin test diameters obtained with these 2 drugs (p less than 0.02 for wheals and p less than 0.01 for flares). Conversely, the lack of concordance between pancuronium and suxamethonium was significant (p less than 0.05). When comparing all the concordances obtained with each pair of drugs, it appeared that the concordance between pancuronium and vecuronium was significantly higher than all others. For other concordances, 2 main factors seemed to play a role: the N+ of the ammonium ions included in a ring as in pancuronium and the presence of a 'choline-like' side chain as in suxamethonium. But there was no significant correlation between skin test diameters. Altogether, these results suggest that in vivo there is no 'true' cross-reactivity between the drugs except frequently between pancuronium and vecuronium. In all other cases, the patients have probably specific IgE antibodies for each drug, all these antibodies being able to recognize the ammonium determinant; this common property may be insufficient to induce a clinical allergy.

Abstract
Airway inflammation is a major component of asthma. Food intake of N-3 fatty acids (FA) is associated with a low incidence of inflammatory diseases, such as asthma. We treated 12 asthmatic patients with FA and report the positive results of this 1-year double-blind study. A positive effect on forced expiratory volume in 1 s was observed after the 9 month of treatment. Our results are in favor of the use of FA, but have to be confirmed by other studies.

Abstract
Allergic anaphylactic (type I) reactions to corticosteroid medications are uncommon; however, a number of well-documented cases have been reported. We present a review of the literature, and report on two patients who suffered anaphylaxis after injections of corticosteroids. The first patient, a registered nurse, was finally found to be sensitive to all corticosteroid preparations containing carboxymethylcellulose, as well as the pure carboxymethylcellulose. The second patient had positive skin tests to hydrocortisone, hydrocortisone sodium succinate, methylprednisolone sodium succinate, and suxamethonium. Both patients were tested on two occasions; four normal subjects were tested in parallel, and did not elicit any positive skin reaction. In patients with systemic severe reactions to injectable corticosteroids, we recommend careful and comprehensive skin testing with most available corticosteroids, as well as the components of the injectables.

Abstract
The specific chromosomal rearrangement t(11;19)(q23;p13) has been identified as a nonrandom chromosomal rearrangement in acute leukemia. The breakpoint, 11q23, coincides with the ets-1 oncogene locus. However, only very few studies have been done to verify the genomic alteration and transposition of ets-1 in the t(11;19) chromosomal rearrangement. In the present study, we identified the t(11;19)(q23;p13) translocation in two acute leukemic cases. One of the cases, biphenotypic leukemia, has been followed thoroughly. An abnormal karyotype was identified in the patient's blood and marrow samples at diagnosis and at relapse, while only normal karyotypes were identified at remission. In situ hybridization of chromosomal preparations with the ets-1 probe pHE5.4 resulted in silver grains nonrandomly localized to 19p13 in the metaphase spreads prepared from the blood sample taken at relapse, while no detectable grains were found on chromosome 19p13 in a sample taken at remission. To determine if genomic alterations of ets-1 are associated with this translocation, Southern blot hybridizations with the pHE5.4 probe were performed on deoxyribonucleic acid (DNA) isolated from blood or marrow samples of the patient at remission and relapse as well as on DNA from a disease-free normal control. Any DNA digested with AvaII, SstI, XbaI, and Bam HI, followed by hybridization with pHE5.4, demonstrated no genomic alterations or amplification of the ets-1 oncogene. Our study indicates that the ets-1 oncogene is transposed in the t(11;19) translocation without detectable alteration at the DNA level. The absence of ets-1 amplification in t(11;19) and its presence in the t(4,11) and t(9;11) translocations demonstrated by others suggests the possible existence of different molecular mechanisms involving the ets-1 oncogene in the pathogenesis of these leukemias.

Abstract
The efficacy and safety of long-acting propranolol (LA.P) 160 mg once-daily in the prophylactic treatment of migraine were tested against placebo in a multicentric, double-blind, randomized study comparing the two groups in a parallel manner over a treatment period of 12 weeks, and following a 4 week-placebo run-in period. Fifty-five out of the 74 patients who entered the trial included at the end of the run-in period. Forty-one patients completed the study. Out of the 14 patients who withdrew from the study, none discontinued because of side-effects. The statistical analysis was done according to the "intention to treat" principle. LA.P was significantly more efficient than placebo in reducing the frequency of migraine attacks (p = 0.01 by variance analysis). LA.P reduced the average number of monthly crises by 48% on day 84. There was a slight but significant reduction of the systolic blood pressure and heart rate in the erect position. There was no significant difference between LA.P and placebo regarding either the number of complaints or the number of side-effects elicited out of an 17 item questionnaire. None of the observed side effects led to a withdrawal of treatment.

Abstract
Chromosome G-banding analysis of two human mammary carcinoma cell lines, Elco and MCF-7, showed the existence of two X chromosomes in both cell lines. To determine the state of activity of the X chromosomes, a methylation-sensitive restriction endonuclease, HpaII, was used to distinguish the active X from the hypermethylated, inactive X chromosome with a probe for the phosphogalactokinase locus by Southern blot hybridization. DNA digested with the restriction enzymes PstI and BstXI showed a band at either 1.05 or 0.9 kilobases. After HpaII digestion, a 50% reduction in intensity was observed in the female controls, whereas total reduction of the band was observed for the tumor cell lines and the male control. This indicates the absence of an inactive X and the presence of only active X chromosomes in the mammary carcinoma cell lines and the male control. To investigate the mechanisms involved in the alteration of the X chromosome composition and activity, restriction fragment length polymorphism analyses of seven additional X chromosome markers (L1.28, DX13, p52A, pX65H7, L782, pA13.RI, and pXG-12) were performed on the DNA isolated from the tumor cells and controls. Heterozygosity for at least one of the seven markers was detected in the six female controls whereas only homozygosity was detected for each marker in the tumor cell lines and the male control. These results indicate that the two active X chromosomes identified in each of the two tumor cell lines are identical, resulting from duplication or nondisjunction of the active X and loss of the inactive X chromosome.

Abstract
Immediate allergic reaction to natural latex of Hevea brasiliensis has been well documented. We report 17 cases, all in women. Twelve had an anaphylactic reaction during surgery and five had contact urticaria. Reactions to prick tests done through a washed surgical glove and with natural latex were positive in 15 of 17 patients and in 16 of 16 patients, respectively; specific IgE was found in 12 of 17 patients. In 206 control subjects, results of a prick test through a surgical glove were negative.

Abstract
Many platelet abnormalities have been described in migraine, but they are now regarded as secondary phenomena rather than primary causative factors. In this study, we attempted to assess the presence of bioamine-releasing factors in the plasma of patients with common, non-dietary migraine. Blood samples were collected from 17 such patients, either during attacks (n = 9) or during attack-free periods (n = 8). Ten healthy volunteers served as controls. Release experiments were performed by adding 1 volume as controls. Release experiments were performed by adding 1 volume of migraineur's platelet-poor plasma to 1 volume of either control's whole blood (histamine release) or isolated platelets (catecholamines or serotonin release). Endogenous unconjugated bioamines were measured in whole blood and in isolated platelets from migraineurs' blood collected during and between attacks. We also measured plasma levels of histamine and of unconjugated and conjugated serotonin and catecholamines, as well as the inhibition of serotonin uptake and labelled serotonin release from controls' platelets in the presence of migraineurs' plasma collected during or between attacks. The results obtained suggest the presence of two plasma bioamine-releasing factors: a histamine-releasing factor present in migraineurs' blood during and between attacks, and a catecholamine and serotonin releasing factor present only during attacks in migraineurs' platelet-poor plasma. The latter factor is thermolabile and dialysable, with an apparent molecular weight lower than 16 kd. Gel-filtered fractions of semi-purified catecholamine-serotonin releasing factor induced the same events as the migraineurs' platelet-poor plasma from which they were obtained.

Abstract
From a series of 30 cases of immediate allergy to the latex of Hevea Brasiliensis, the authors recall the principal clinical aspects of these allergies, specially contact urticaria (during the use of surgical or cleaning gloves) and systemic anaphylactic accidents, essentially the anaphylactic shock during surgical procedures. They mention the diagnostic procedures; skin tests and measurement of specific IgE (RAST). They show the interest of biological research, yielding to the identification of the allergens of the latex in order to obtain non allergenic latex. Such a result would be of interest to limit the number of the accidents in a period where the use of rubber protective material is much larger/gloves and condoms).

Abstract
The aim of the study was to determine whether IgG antibodies from patients on specific immunotherapy could inhibit skin test reactivity of allergens when mixed with them prior to testing. In a preliminary double-blind study, mite extracts were incubated with glycero-saline solution or non-specific IgG and used in testing 15 patients. Wheal and flare diameters produced with the two mite extracts did not differ significantly. In a second double-blind study with 15 other patients, skin tests using mite extracts incubated with either non-specific IgG or specific IgG showed significantly decreased diameters when mite extracts were preincubated with specific IgG. This result, in vivo, confirms the antigen neutralizing capacity of specific IgG demonstrated in vitro.

Abstract
Five young women, all of whom had anaphylactic responses in operating units, are described. Three of them worked in a hospital three showed immediate hypersensitivity to fruit and all had known urticaria to latex. Anaphylaxis appeared progressively 15 to 30 minutes after injection of anaesthetic drugs. Skin tests with these drugs were negative. Skin prick tests through gloves and with four different allergen preparations (saline which had been incubated with gloves and three kinds of latex) were positive. Human basophil degranulation tests with all four allergens were positive and radio allergo sorbent tests to latex were also positive. IgE-dependent allergy to latex may be investigated by questionnaire and if necessary by prick tests before each operation to prevent anaphylaxis due to surgical gloves.

Abstract
A retrospective postal inquiry was carried out to find out a possible relation between the results of intradermal tests carried out for a previous anaesthetic and the course of a second anaesthetic performed afterwards. This study included 350 patients who have had an intradermal test to vecuronium, alcuronium, suxamethonium, gallamine, pancuronium, thiopentone, fentanyl and droperidol between March 1984 and November 1986. Eighty-nine did not reply (25.4%), 183 (52.3%) did not undergo new general anaesthetic since the skin tests, whilst 78 (22.3%) did. The inquiry was then sent to the 73 anaesthetists corresponding to the last group of patients. The 51 complete answers included 62 anaesthetics. Twenty-four patients had negative intradermal tests before the new anaesthetic, the other 27 having had a test positive to at least one muscle relaxant. Of these latter, 16 were given a muscle relaxant during their general anaesthetic, selected among those resulting in a negative intradermal test. Thirteen had undergone skin testing because of an anaphylactic reaction during induction. No new anaphylactic reaction was observed. Three anaesthetists only were not aware of the results of the intradermal tests at the time of the new anaesthetic. These data tend to demonstrate that a muscle relaxant could be injected in a patient who has had a previous anaphylactic reaction with positive intradermal tests, provided that the drug chosen for the new anaesthetic does not give a positive intradermal reaction.
