bee-sting anaphylaxis in childhood.the syndrome of bee-sting anaphylaxis is described. children who have suffered crescendo reactions to previous bee stings, especially children with a history of asthma, are significantly at risk. desensitization is required in such cases; adrenaline should be kept in the home, and parents should be trained in its emergency use. the immunological mechanisms of bee-sting anaphylaxis are described. the striking seasonal incidence of anaphylaxis suggests that pollen or plant products which are incor ...1979514147
flower-feeding specialization in wild bee and wasp communities in seasonal neotropical habitats.flower visitation records were obtained for 192 species of bees and 138 species of wasps in three neotropical habitats. four indices of feeding specialization were calculated for common species, and similar patterns were observed using each index. variation in specialization could be attributed to several factors: the habitat and season in which species were found, the degree of sociality of species, and whether species were bees or wasps. important differences among habitats and seasons were th ...197928309659
[comparative analysis of thermoregulation in the nests of certain species of social insects].studies have been made on thermal regulation in the nests of families of the honey bee apis mellifera, wasp dolihovespula silvestris and bumblebees bombus terrestris, b. agrorum and b. lapidaris during their maximum development. it was shown that thermoregulation significantly stimulated the brood in the nest. among the species investigated, the highest thermoregulatory capacities are exhibited by honey bees, this fact being associated with the large number of individuals in their colonies. duri ...2010506590
ige antibodies to bee venom, phospholipase a, melittin and wasp venom.specific ige antibodies against bee venom, phospholipase a, melittin and wasp venom have been examined in fifty patients with an unusually severe reaction after bee or wasp sting. two thirds of the bee venom-sensitive patients also have detectable ige antibodies to wasp venom. more than 50% of the wasp venom-sensitive patients are also allergic to bee venom. phospholipase a and melittin ige antibodies were found, respectively, in two thirds and one third of the bee venom-sensitive cases. specifi ...1979498494
the first optic ganglion of the bee. iii. regional comparison of the morphology of photoreceptor-cell axons.the nine receptor cells in each ommatidium of the worker bee end as six short visual fibres in the lamina and as three long visual fibres in the medulla. behavioural and physiological evidence for regional variation in spectral sensitivity prompted observations on the morphology of the visual units. the distribution, branching pattern, diameter and the arrangement of axonal protusions of the characteristic receptor-cell axons were studied in various regions of the lamina. the six short visual fi ...1979487403
measurement of the potency of pollen extract by radioimmunoprecipitation.we describe a novel procedure for standardization of allergen extracts using radioiodinated crude extracts. radiolabeled extracts were reacted with immunoglogulin e (ige) antibody, and the resulting complexes precipitated by anti-ige. experiments with ragweed pollen, grass pollen, honeybee venom, and alternaria extracts revealed that 1% to 14% of the radioactivity was precipitated, these percentages ranged from 2 to 20 times blank values. binding of labeled ragweed extracts to ige antibody could ...1979469117
[the basophil degranulation test in the diagnosis of bee and wasp sting allergies].comparison of basophil degranulation test (bdt) with radioallergosorbent test (rast) in 50 patients with anamnestically certain or probable hymenoptera allergy yielded practically equal results. in patients who had experienced their allergic reaction a long time ago, bdt seemed to react positively over a longer period of time than rast. as bdt is technically easy to perform and moderate in price, it is suited to substitute rast.1979493908

comparison of skin tests and rast for the diagnosis of bee sting allergy.skin tests and estimation of specific ige-antibodies by the rast are evaluated as diagnostic procedures in bee sting hypersensitivity with the followiny extracts. (2) with bee venom results of skin tests and rast correspond in 82%, with bee wholebody extracts in 68%. (3) both with skin tests and the rast with bee venom a good discrimination between patients with bee sting hypersensitivity and non-allergic controls is observed. skin tests with bee venom are somewhat more sensitive than bee venom- ...1979517710
enzymes of bee venom, sac and whole body.by using the api-zym system 55 enzymes were determined to be present in bee venom, venom sac, sacless whole body extract and whole body commercial extracts. acid phosphatase activity was high in bee venom and sacless whole body extracts. arylamidase activities were elevated in sacless whole body extracts and very low or undetectable in venoms. conversely, glycyl-prolin arylamidase activity was high in venoms and very low in the other extracts.197937787
influence of enzymatic phospholipid cleavage on the permeability of the erythrocyte membrane. ii. protein-mediated transfer of monosaccharides and anions.in order to investigate the influence of membrane lipids on transport via the protein domain of the erythrocyte membrane, a number of facilitated diffusion processes was studied by tracer flux techniques in whole cells after cleavage of up to 65% of the phosphatidylcholine or the sphingomyelin by phospholipase a2 from naja naja or bee venom, or by sphingomyelinase, respectively. the mediated fluxes of l-arabinose, which is transported by the glucose carrier, and of l-lactate, which uses a specif ...1979486450
natural history of allergy to hymenoptera.one hundred and nineteen patients who had a generalized reaction to a bee sting and who subsequently had a history of being re-stung before desensitization were studied. the reaction, in these 119 patients was as follows: 44.5% had an improved grade of reaction, 42.9% had the same grade of reaction and 12.6% had a worse grade of reaction. of these 119 patients, 39.5% had only a local reaction to their re-sting. those patients who were re-stung within 2 weeks (anergic period) or over 5 years afte ...1979476909

natural polyesters: dufour's gland macrocyclic lactones form brood cell laminesters in colletes bees.bees in the genus colletes make their brood cells in the ground and coat them with a highly resistant, waterproof, transparent membrane. this membrane is a polyester constructed mainly from 18-hydroxyoctadecanoic acid and 20-hydroxy-eicosanoic acid, which are stored as their corresponding lactones in the dufour's gland of the bee. when lining the cells, the bee secretes its glandular content, and the membrane is apparently a product of polycondensation reaction of its contents. this appears to b ...197917758016
enzyme-linked immunosorbent assay of allergen-specific igg antibodies in bee sting allergic patients hyposensitized with pure bee venom.an elisa is presented for detection of igg antibodies to bee venom. by this method, sera of 11 bee sting allergic patients, who were treated with rapid hyposensitization with pure bee venom, were tested. the highest antibody titers were observed after 30 days of treatment, a maximum rise of 7.4 +/- 1.5 log 2-titer steps. pure bee venom is shown to be more potent immunologically than whole body bee extract. prediction of the clinical success, measured by tolerance to a bee sting challenge, is not ...1979459376
the use and interpretation of rast to stinging insect venoms.quality controlled, standardized rast systems for five stinging insect venoms are described. these systems were evaluated using 375 sera from insect reactive patients from six diverse geographic regions. ninety-four percent of patients with recent histories of systemic allergic reactions to stings were positive to at least one venom while 4 percent of normal local reactors were positive. the cross reactions between honey bee and vespid venoms were studied by rast inhibition. a quantitative metho ...1979434584
population dynamics of sex-determining alleles in honey bees and self-incompatibility alleles in plants.mathematical theories of the population dynamics of sex-determining alleles in honey bees are developed. it is shown that in an infinitely large population the equilibrium frequency of a sex allele is 1/n, where n is the number of alleles in the population, and the asymptotic rate of approach to this equilibrium is 2/(3n) per generation. formulae for the distribution of allele frequencies and the effective and actual numbers of alleles that can be maintained in a finite population are derived by ...197917248901
[epidemiological studies on the symptoms due to strawberry culture in the vinyl-house. 2. an analysis of clinical examinations with emphasis on allergic response (author's transl)].clinical mass surveys were carried out on the residents to whom questionnaires on symptoms with reference to strawberry culture in the vinyl-house had been delivered. two hundred and eleven persons attended at the first survey in september, 1976 (off the season of strawberry culture) and the 58 attended at the second survey in march, 1977 (within the season). the participants of the first survey consisted of three groups, i.e. farmers with and without strawberry culture and people without farmin ...1979491286
solid phase synthesis of 13-lysine-apamin, 14-lysine-apamin and the corresponding guanidinated derivatives.in order to study the importance of arginine residues 13 and 14 in apamin, the bee venom neurotoxin, four analogues, [lys13]-apamin, [lys14]-apamin, [har4, har13]-apamin and [har4, har14]-apamin were synthesized and tested with respect to their neurotoxicity. the two lysine-apamins were prepared by the solid phase method on benzhydrylamine resins. before oxidation to disulphides, the (s-acm)4-peptides were isolated and characterized. portions of the purified lysin peptides were converted to homo ...1979429106
desensitization of patients with bee sting allergy using pure bee venom.forty patients who had previously experienced severe systemic reactions after a bee sting were desensitized using pure bee venom. a modified 'rush' regimen was employed whereby patients received two injections a week and reached maximal desensitization in 5 weeks. eleven patients have subsequently been stung again and have developed no generalized reaction. although this form of desensitization is considered to be highly effective in protecting sensitive patients, both generalized and local side ...1979375434

honey bee venom allergy immunological studies of systemic and large local reactions.the ige and igg antibody responses to four allergen fractions of honey bee venom were studied in 13 sera from patients who experienced systemic reactions from bee stings and eight from those who experienced large locals. both groups were similar in allergen response. ige and igg levels and ratios. a significant number of patients were found to have experienced both types of reactions from bee stings. it is proposed that ige antibody positive systemic and large local reactions are both ige mediat ...1978717848
[hyposensitisation treatment with pure bee venom (author's transl)].hyposensitisation with pure bee venom was undertaken in eleven persons with proven allergy to bee stings. rapid hyposensitisation led to side effects in seven of them during dosage increase. serial determination of total iga, igg, igm and alpha1-antitrypsin revealed no changes, while allergen-specific igg and ige and total ige increased maximally after 30 days. all persons were exposed to one bee sting during the treatment: all tolerated it well without the allergic reactions which had previousl ...1978308876
competitive interactions between neotropical pollinators and africanized honey bees.the africanized honey bee, a hybrid of european and african honey bees, is thought to displace native pollinators. after experimental introduction of africanized honey bee hives near flowers, stingless bees became less abundant or harvested-less resource as visitation by africanized honey bees increased. shifts in resource use caused by colonizing africanized honey bees may lead to population decline of neotropical pollinators.197817743636
the use of the radioallergosorbent test in the diagnosis of hymenoptera anaphylaxis.ige antibody levels to hymenoptera (honey bee, hornet, wasp or yellow jacket) venom or venom sac were measured in the serum of ninety-six patients with a history of immediate hypersensitivity reactions to these insect stings. normal levels of ige antibody were found in fourty-four of these patients tested. the severity of the systemic reaction was similar in those patients with normal and elevated ige antibody levels, and the interval from the systemic reaction to antibody determination was also ...1978709792

diagnosis of honey bee venom allergy.studies using both an optimized rast assay and intradermal skin testing with whole bee venom indicate that both methods should be used for diagnosis. rast and skin test are of similar sensitivity but each misses some patients found positive by the other. correlation between the tests was 91% with an additional 5% only rast positive and 4% only skin test positive.1978646187
[the role of the glial cells in the maintenance of the ionic environment of the photoreceptors of the retina of the drone (author's transl)].a double-barrelled potassium sensitive microelectrode was used to record electrical potentials and k+ activities in the retina of the drone apis mellifera during stimulation with trains of flashes, 1 per sec, intense enough to produce receptor potentials of near maximal amplitude. during the stimulation photoreceptors lose about 25% of their intracellular potassium concentration. during stimulation the potassium activity in the extracellular space increased transitorily up to 20 mm and then fell ...1978651211
solid phase synthesis of apamin, the principal neurotoxin in bee venom. isolation and characterization of acetamidomethyl apamin.the synthesis of apamin, the principal neurotoxin in bee venom, has been accomplished by the solid phase method on a benzhydrylamine resin, 2-phenylisopropyloxycarbonyl amino acids were used throughout the synthesis except for the c-terminal histidine. improved yields in the coupling steps in the n-terminal part of the molecule were obtained by coupling each amino acid both in dichloromethane and dimethylformamide. the use of acetamidomethyl as an s-protecting group for cysteine made it possible ...1978649258
allergens in hymenoptera venom. v. identification of some of the enzymes and demonstration of multiple allergens in yellow jacket venom.yellow jacket venom (yjv) contains acid phosphatase, hyaluronidase and phospholipase but neither allergen c nor melittin as bee venom (bv). yjv enzymes did not cross react with antisera to bv enzymes. yjv was separated into seven fractions, all of which had some activity in rast. sera were found specific for the fractions containing phospholipase and acid phosphatase. the other three protein fractions also exhibited substantial rast activity, suggesting there are at least five allergens in yjv.1978637376
the structures of some peptides from bee venom.the sequences are given of two peptides (secapin and melittin f) whose isolation from the venom of the common european honey bee (apis mellifera) has previously been described [gauldie et al. (1976) eur. j. biochem. 61, 369--376]. some structural studies on the known peptide 401 (mcd peptide) are described. the positions of the two disulphide bridges in peptide 401 have been determined by (an essentially) novel method.1978631126

[determination of the kinetic parameters of enzyme inhibition of the k-type mechanism: application to the control of alpha-glucosidase activity of honeybee hemolymph by glucose].the alpha-glucosidasic activity of emerging honeybees haemolymph is submitted to a feed-back inhibition by glucose, according to a mechanism of the "k" type (competitive). the "resulting affinity-constant" (measured in the presence of the enzyme both with substrate and inhibitor) is linear function of the inhibitor concentration. the affinity constants between enzyme and pure substrate on one hand, and between enzyme and pure inhibitor on the other hand, were determined by means of this relation ...1977409564
separation and detection of phencyclidine in urine by gas chromatography.a rapid, sensitive and selective analytical procedure for phencyclidine and one of its metabolites in urine has bee developed. three techniques have been studied for extraction of the drug from the biological matrix: (a) reversed-phase xad resin, (b) charcoal absorption, and (c) solvent extraction using chloroform. temperature-programmed gas chromatography was used to quantitate the illicit drug. solvent extraction appears to offer the most efficient separation of the drug and its metabolite, as ...1977893578
[modification of alpha-glucosidases (e.c. 3.2.1.20) activity in honeybee hemolymph during nymphosis].the main alpha-glucosidase fraction of honey-bee hemolymph undergoes an important increase of activity for a short time, at a precise stage of nymphosis (pink-brown eyes), without any changes of the apparent-michaelis constant, nor corresponding increase of the protein quantity.1977409545

estimation of the number of sex alleles and queen matings from diploid male frequencies in a population of apis mellifera.the distribution of diploid males in a population of apis mellifera was obtained by direct examination of the sexual phenotypes of the larvae. using these data, estimates are derived for the number of sex alleles and the number or matings undergone by the queen. the number of sex alleles is estimated to be 18.9. the estimate is larger than previous ones, which have ranged between 10 and 12. however, the increase in the number of sex alleles can be explained by the large effective population numb ...1977892423
concept of internal structural controls for evaluation of inactive synthetic peptide analogs: synthesis of [orn13,14]apamin and its guanidination to an apamin derivative with full neurotoxic activity.the importance of arginine residues 13 and 14 in the bee venom neurotoxin, apamin, was teste by the synthesis of replacement analogs. [13,14-di-ndelta-trifluoroacetylornithine]apamin was synthesized by the solid phase method on a benzhydrylamine resin. it was deprotected to [13,14-diornithine]apamin, which was then guanidinated to produce the 4-homoarginine-13,14-diarginine analog, [har4]apamin. neither the trifluoroacetylornithine analog nor the ornithine analog produced any detectable symptoms ...1977268626
[value of total thyroidectomy with cervical dissection in the treatment of differentiated thyroid cancers].study of 52 cases of differentiated carcinoma of the thyroid treated by anatomically total thyroidectomy with block dissection of the cervical nodes indicated three amin findings: examination by puncture for cytological examination would have missed 8 micro-carcinomas; unilateral excistion would have bee inadequate in 12 patients; lymph node excision confined to detectable lymphadenopathies would have left neoplastic tissue in place in 8 cases. in the light of these advantages from an oncologica ...1977887418

incorporation into lipid bilayer membranes of a photo--sensitive pigment from the honeybee compound eye.an increase of electrical conductance up to a factor 10(2)--5-10(2) was obtained by adding, in the dark, the honeybee photopigment to a positively charged lipid bilayer. the increase in conductance was made slower by illuminating the system during the incorporation of the protein into the membrane and it was negligible when the photopigment was bleached before the incorporation. the interaction of the photopigment with the membrane is tentatively interpreted in terms of formation of channels.1977861223

allergens in hymenoptera venoms. iv. comparison of venom and venom sac extracts.honeybee venom sac extract is compared with pure venom. all five known allergens of venom are present in venom sac extract. enzyme analyses indicate that the sac extracts contain 11% to 16% venom. at least 10 additional components, several of which are proteins, are present in venom sac extract. radioallergosorbent test (rast) studies of yellow jacket venom and venom sac extract yielded a correlation of r = 0.94, with only some weakly reactive sera positive to only one preparation. a few sera we ...1977856902
allergens in bee venom. iii. identification of allergen b of bee venom as an acid phosphatase.allergen b previously isolated from honeybee venom and shown to be a mildly acidic protein consisting of polymers of a chain of 49,000 d is shown to have acid phosphatase activity. allergen b is homogeneous by several criteria. no acid phosphatase, alkaline phosphatase, or esterase activity was found in any other allergen or fraction of bee venom. acid phosphatase activity was also found in yellow jacket venom and extracts of venom sacs from bumblebees and paper wasps.1977853176
serological investigations in hymenoptera sting allergy: ige and haemagglutinating antibodies against bee venom in patients with bee sting allergy, bee keepers and non-allergic blood donors.specific ige-antibodies and haemagglutinins to bee venom were determined in fifty-five bee sting allergic patients, fifty-seven bee keepers and fifty-two blood donors without evident allergy to hymenoptera stings. ige-antibodies were detected by rast in 70% of allergic patients, 40% of bee keepers and 12% of blood donors. most bee keepers with detectable ige-antibodies to bee venom recorded severe local or even general reactions to bee stings. most blood donors with detectable specific ige had b ...1977872361
[basic peptides in bee venom, iii. synthesis of peptide fragments from the sequence of the mast-cell-degranulating peptide (author's transl)].the synthesis by conventional methods of the following three peptides is described: mcd(8-11) boc-his(trt)-val-ile-lys(z) (iii) mcd(5-7) boc-cys(sipr)-lys(z)-arg(tos) (iv) and mcd(1-4) boc-ile-lys(z)-cys(trt)-asn(mbh) (v). these peptides are fragments of the mast cell degranulating peptide from bee venom. the purity of the fragments synthesized was examined by thin-layer chromatography, amino acid and elementary analysis. including the fragments boc-lys(z)-ile-cys(sipr)-gly-lys(z) (i) and boc-pr ...1977856709
