clinical application of measurements of serum level of bee venom-specific ige and igg.bee venom--specific ige and igg antibodies were measured in the serum of beekeeepers, bee-allergic persons, and normal persons infrequently stung without adverse effects. beekeepers, who are stung frequently and relatively "immune" to bee stings, are characterized by high serum levels of igg- and low serum levels of ige-specific antibodies. bee-allergic individuals have high titers of bee venom--specific igg. following a bee sting, allergic individuals develop a rising titer of ige antibodies, a ...1977838994
fertile diploid drones in africanized honeybees, apis mellifera adansonii.59 diploid drones of apis mellifera adansonii, 12-37 days old, were tested for the presence of semen after provoked ejaculation; 13 drones ejaculated semen enough to be used in an instrumental insemination, but only three on them (5%) furnished 1 mm3 of semen. the problems referring to the attainment of descendants from the 2n drones are briefly discussed.1977844541

protection against anaphylaxis in hymenoptera-sensitive patients by passive immunization.passive administration of specific immunoglobulin led to a transient rise in antiphospholipase igg. an observed rise of 2 microgram/ml (twofold in three cases) was associated with a very diminished response to bee venom. this did not prevent the patient's own igg response to challenge, which was at least as good as that of non-infused patients. the infusion of igg cannot be proposed at present as a routine mode of therapy in insect allergy. however, we present the results of our study as the bes ...1977303327
diagnosis of hymenoptera hypersensitivity by skin testing with hymenoptera venoms.this double-blind study provides evidence that skin testing with dialyzed hymenoptera venoms is a more accurate, reliable method of diagnosing hypersensitivity to the sting of honeybee, yellow jacket, yellow hornet, white-faced hornet, and wasp than is skin testing with the corresponding whole body diagnostic allergenic extract. furthermore, the incidence of false-positives was greatly reduced by using the dialyzed hymenoptera venom (hdv) diagnosis. in this clinical trial, most sensitive individ ...197764482

contrasting patterns of dna sequence arrangement in apis mellifera (honeybee) and musca domestica (housefly).we have examined the organization of the repeated and single copy dna sequences in the genomes of two insects, the honeybee (apis mellifera) and the housefly (musca domestica). analysis of the reassociation kinetics of honeybee dna fragments 330 and 2,200 nucleotides long shows that approximately 90% of both size fragments is composed entirely of non-repeated sequences. thus honeybee dna contains few or no repeated sequences interspersed with nonrepeated sequences at a distance of less than a fe ...19761001163
determination of renin-dependency and sodium-dependency in the three renin sub-groups of essential hypertension.1. in all three renin sub-groups of essential hypertension, the state of sodium balance determines the degree of participation of the renin-angiotensin system in sustaining high blood pressure. 2. even the low-renin type can become renin-dependent when sufficient sodium depletion has bee achieved. 3. the main difference between patients of these sub-groups appears to be their variable capacity to become depleted of sodium under standard dietary regimens.19761071607
[basic peptides in bee venom, ii. synthesis of two pentapeptides from the sequence of the mast-cell-degrading peptide (author's transl)].the synthesis of two protected pentapeptides is described. the peptides are fragments of the sequence of a mast-cell degranulating peptide from bee venom. the fragments boc-lys(z)-ile-cys(sipr)-gly-lys(z)(i) and boc-pro-his(trt)-ile-cys(trt)-arg(tos) (ii) were synthesized conventionally. the deprotection of the alpha-amino group by hcl/acetic acid of boc-ile-cys(sipr)-gly-lys(z) was accompanied by a disulfide exchange at the cysteine residue. after the hydrolysis of fragment ii with 6n hcl, allo ...19761017794
[mechanisms in the group effect of honeybees].we consider the group effect on the mortality rate of honeybees and on the development of certain of their organs the mortality rate isolate honeybee varies according to the time of year, which leads us to believe that the group effect has an alimentary origin, at least at the outset. a sensory and perhaps pheromonal origin is equally demonstrated. moreover, there is a group effect on most of the organs studied.1976828538
[a new monogenean parasite (bouixella n. g.) in the mormyridae (teleosts) of benin].study of the monogenean gill parasites occuring in the mormyrid fish from benin (africa). description of a new genus, bouixella. it differs from the other ancyrocephalidae by the number (4) of cross bars between the haptoral hamuli. this new genus seems to bee specific of the mormyridae among which a new example of simultaneous gill parasitism by congeneric species is reported.1976828533
allergenic potency of bee antigens measured by rast inhibition.the potency of various bee antigens including bee venom, several whole bee body extracts and fractions of bee venom was studied using the rast inhibition method. as compared to whole bee body extract, bee venom was a much more potent inhibitor of both bee venom and whole body rast, suggesting that venom has a greater capacity to bind specific bee ige antibodies. whole body extracts also varied substantially in their inhibiting activity. phospholipase a and hyaluronidase were the most potent of t ...19761016291
[variation of the 9-keto-2-decenoic acid content as a function of age in virgin queen-bees (apis mellifica ligustica s.)].we measured the amount of 9-oxodec-2-enoic acid in virgin honeybee queens 1 to 50 days old. we chose 4 age ranges: from 1 to 6, from 16 to 20, from 26 to 30, from 40 to 50 days. queens 16 to 20 days old contain most 9-oxodec-2-enoic acid (average : 1 107 mug). the observed variations in amounts should partly depend on the physiology of attending workers. the authors discuss the mechanisms responsible for the action of 9-oxodec-2-enoic-acid.1976827382

effects of fructose-1,6-diphosphate administration on learning efficiency and time sense of the honey bee, apis mellifica carnica.in discrimination experiments honey bees had to decide between two glass dishes, one placed on a black cross, the other 40 cm away on a black square. in spontaneous selections the bees in 70% of all cases chose the black cross. the bees were then trained to search back and forth between the cross and the square until after 5 min sugar-water was given on the black square. over a total of 5 learning trials, during which multiple decisions had been made by the searching insects, 96% of all choices ...1976953767
[relationships between thyrotropin, growth hormone and insulin in hypothyroidism].since growth hormone has been found to be inhibited in many cases of untreated primary hypothyroidism, we tried to investigate whether the high thyrotropin levels or the lack of thyroid hormones is the responsible factor. six primary hypothyrotic patients were kept euthyroid by means of high and constant doses of thyroid extract. growth hormone immunoassays were performed before and after three days of thyrotropin stimulation. immunoassayable insulin was also investigated under the same experime ...2011973855

second-order ocellar neurons in the brain of the honeybee (apis mellifera).electrophoretic injection of procion yellow m-r4 into the ocellar tract of the worker bee has revealed the following: two types of giant axon run from the lateral ocellus to the circumesophageal neuropile, where one branches ipsilaterally and the other contralaterally. a third type comes from the median ocellus and can be traced into the cervical connectives. the largest dendritic complex is in the circumesophageal neuropile; in addition, fiber endings have been demonstrated in the following are ...1976963737
a kinetic analysis of the changes in fluorescence on the interaction of 8-anilinonaphthalene-1-sulphonate with submitochondrial particles.a comparison of the fluorescence change on the addition of 8-anilinonaphthalene-1-sulphonate to succinate-energized submitochondrial particles with that on the addition of succinate to submitochondrial particles incubated with 8-anilinonaphthalene-1-sulphonate shows that these changes in fluorescence may be explained solely in terms of 8-anilinonaphthalene-1-sulphonate binding. this comparison does not support the proposal of an 8-anilinonaphthalene-1-sulphonate-monitored change in the conformat ...1976985430
the organization of perpendicular fibre pathways in the insect optic lobe.high resolution serial photomicrography has been used to plot the axonal projection patterns between retina, lamina and medulla in the optic lobes of various insects with differing ommatidial receptor arrangements. observations are reported on the cabbage white and skipper butterflies, the bee, locust, fly, backswimmer and waterbug. the patterns of these fibre pathways have previously eluded non-rigorous analyses primarily because of their physical dimensions but are revealed in this study to ha ...197611512
adder bites in britain.ninety-five cases of adder bite that have occurred in britain over the past 100 years are reviewed. most bites occurred in men who foolishly picked up the adder. three-quarters of the victims reached hospital within two hours of the bite. when venom is injected the early symptoms include local swelling and discoloration, vomiting, diarrhoea, and early collapse, which often resolves spontaneously. in severe poisoning persistent or recurrent shock is the main feature. children recover quickly but ...19761276841
immunologic comparison of phospholipases a present in hymenoptera insect venoms.a comparative study was made of the effect of anti-bee venom phospholipase a2 serum and anti-bald face hornet venom serum on the activity of phospholipase a2 present in yellow hornet, yellow jacket, bald face hornet, and honeybee venoms. activity of phospholipase a2 present in the venoms was measured titrimetrically using egg yolk dispersion as the substrate. antiserum against pure bee venom phospholipase a2 activity completely suppressed bee venom phospholipase a2 activity but failed to inhibit ...1976947973
[studies on the rectal pads of the honey bee apis mellifca].according to earlier investigations young bees show a rectal fluid hypo-osmotic to the haemolymph. it had been assumed, however, that in certain situations honey bees have to be economical with water and simultaneously form a rectal fluid hyperosmotic to the haemolymph. the latter has been confirmed by the present investigation.2016134591
heat exchange in relation to blood flow between thorax and abdomen in bumblebees.1. the narrow passage within the petiole between thorax and abdomen is anatomically constructed so that counter-current exchange should retain heat in the thorax despite blood flow to and from the cool abdomen. 2. however, the counter-current heat exchanger can be physiologically circumvented. exogenously heated bumblebees prevented overheating of the thorax by shunting heat into the abdomen. they also regurgitated fluid, which helped to reduce head temperature but had little effect on thoracic ...1976945321
immunological studies of the effect of whole body insect extracts in the treatment of stinging insect allergy.specific ige antibodies and total antibodies reacting with bee venom and yellow jacket venom were measured in sequential serum samples of insect-sensitive individuals. venom-specific ige decreased as a function of time and was not significantly affected by treatment with whole body extracts. there was no stimulation of total antibodies reacting with bee venom phospholipase a2 (pla) following treatment with whole bee body extracts. these studies suggest that as measured by these parameters, whole ...1976932341

activities of antennal and ocellar interneurones in the protocerebrum of the honey-bee.1. unit responses to olfactory and mechanical stimuli of the antennae, and illumination of the ocelli, were recorded extracellularly in the protocerebrum of the honey-bee. 2. bimodal units responded both to antennal and to ocellar stimuli; antennal units responded to the former and the ocellar units to the latter. some antennal units responded to olfactory stimuli (olfactory units), and others responded to mechanical stimuli (mechanical units). 3. ocellar units in the brain showed phasic respons ...1976932626
role of intracellular calcium and sodium in light adaptation in the retina of the honey bee drone (apis mellifera, l).in the honey bee drone, the decrease in sensitivity to light of a retinula cell exposed to background illumination was found to be accurately reflected by the difference in amplitude between the initial transient depolarization and the lowest steady depolarization evoked by the background light. it is shown that both the decrease in sensitivity to light and the accompanying drop in potential from the transient to the plateau can be prevented by injecting egta intracellularly. a decrease in durat ...1976818341
