| prolonged interval maintenance venom immunotherapy. | current guidelines recommend indefinite administration of venom immunotherapy at 4-week intervals. to simplify this therapy, we examined the clinical and immunologic response after extending the interval between maintenance venom injections to 6, 8, and 12 weeks. twenty-six patients who had had sting anaphylaxis and positive skin tests received maintenance bee or yellow jacket venom immunotherapy at greater or equal to 6-week intervals. this extended interval was started after a prior average 4- ... | 1988 | 2458060 |
| temperature-dependent shift of fluorescence spectra without conformational changes in protein; studies of dipole relaxation in the melittin molecule. | when studying bee venom melittin in an ordered tetrameric form we found a shift of the fluorescence spectrum to a longer wavelength with a rise in temperature above 25 degrees c. the application of the methods of circular dichroism, temperature-perturbation difference spectrophotometry, gel filtration, ionic quenching and polarization of trp-19 fluorescence argues against the possibility of dissociation and change in conformation with the rise in temperature. the spectral shifts are, probably, c ... | 1988 | 3401493 |
| the role of insect water balance in pollination ecology: xylocopa and calotropis. | two carpenter bees (xylocopa spp.) in southern israel both use the asclepiad calotropis procera as a primary nectar source. this plant genus is coevolved with carpenter bees, and aspects of the insect-flower interaction in israel suggest that the smaller bee, x. sulcatipes, is the natural co-adapted pollinator, a view borne out by the geographical distributions of the species concerned. there are significant mismatches between the plant and the larger x. pubescens, involving physical fit and beh ... | 1988 | 28312024 |
| in situ localization of the transcripts of a homeobox gene in the honeybee apis mellifera l. (hymenoptera). | we have isolated and characterized a homeoboxcontaining gene from the honeybee apis mellifera. its homeobox region shows a high degree of sequence similarity to the homeobox of the drosophila gene deformed (dfd). at the dna level 82% of the basepairs are the same, whereas the putative amino acid sequences are identical between the bee and the fruitfly genes. similarity is also present 5' and 3' to the homeobox. using this isolate as a probe we have performed in situ hybridization on sections fro ... | 1988 | 28305786 |
| structure of p401 (mast cell degranulating peptide) in solution. | p401 (also known as mast cell degranulating protein, mcd) is a minor component of honeybee venom. its primary structure is related to that of apamin. we have studied the structure of p401 in solution by high-resolution two-dimensional 1h-nmr spectroscopy. almost all the backbone proton resonances have been assigned by sequential assignment strategy. analysis of noes shows that p401 has a conformation very similar to that of apamin. n-terminal residues ile-1-cys-5 are in an extended conformation ... | 1988 | 3233281 |
| spin-label assay for phospholipase a2. | a rapid and continuous method for measuring phospholipase a2 activity using electron spin resonance spectroscopy and a spin-labeled phospholipid as a substrate has been developed. the substrate, 1-palmitoyl-2-(4-doxylpentanoyl)glycerophosphocholine, gives rise principally to a broad esr line in aqueous solution due to strong spin-spin interactions, probably resulting from its micellar formation. upon addition of bee venom phospholipase a2, the water-soluble product, 4-doxylpentanoic acid, is rel ... | 1988 | 2847584 |

| social plasticity and early-diapausing females in a primitively social bee. | many of the females of the first summer brood of the sweat bee halictus rubicundus mate, soon vanish from the nesting site, undergo diapause, and return unworn the following spring to found their own nests without ever functioning as workers. roughly half a season's foundresses may originate in this way. this finding contradicts previous assumptions regarding timing of reproductive production in sweat bees and offers a remarkable example of intraspecific social diversity; some females in the pop ... | 1988 | 16593945 |
| [effect of nutritional treatment of esophageal cancer patients on pre and post-operative hemodynamic changes and postoperative lung complications]. | in 35 patients with esophageal cancer, preoperative nutritional state and hemodynamic changes on exercise test using swan-ganz catheter were studied. thirty-five patients were divided into two groups. group 1; preoperative daily calorie intake was less than 1.75 x bee (basal energy expenditure), group 2; preoperative daily calorie intake was more than 1.75 x bee. there were significant differences between group 1 and group 2 in preoperative daily calorie intake, serum transferrin, retinal bindin ... | 1988 | 3185468 |
| glutamate-like immunoreactivity in identified neuronal populations of insect nervous systems. | glutamate is considered to be the most likely transmitter candidate at excitatory synapses onto skeletal muscles of insects. we investigated the distribution of glutamate-like immunoreactivity (glu-li) in identified motor neurons of glutaraldehyde-fixed metathoracic ganglia of the locust in paraffin serial sections. the presumably glutamatergic fast and slow extensor tibiae motor neurons show glu-li, whereas other cells, including the gabaergic common inhibitory motor neurons and the cluster of ... | 1988 | 2898517 |
| severe anaphylactic reactions outside hospital: etiology, symptoms and treatment. | twenty-seven patients with severe anaphylactic reactions were treated by two anesthesiologist-staffed ambulance helicopters during a 5-year period. all patients had signs of respiratory and/or circulatory failure. cutaneous symptoms were described in 70% of the patients, gastrointestinal symptoms in 30% and central nervous symptoms in 85%. wasp sting and drugs were the most common causes. other etiologies were bee sting, snakebite, nuts and exercise. all patients were provided with advanced pre- ... | 1988 | 3394485 |
| synthesis of two allergenic constituents of propolis and poplar bud excretion. | the prenyl ester and the phenylethyl ester of caffeic acid, formed in the bud excretion of poplar species, were shown recently to be the major contact allergens in bee-glue. an unambiguous synthesis of these compounds, based on the reaction of caffeic acid with 1-bromo-3-methyl-2-butene and with beta-bromoethylbenzene, respectively, is reported. the synthetic products confirm the previously described structures of the natural products and allow further testing of their allergenic properties. | 2013 | 2458657 |
| [nutritional support for preoperative patients with esophageal cancer]. | nutritional support for patients undergoing major operations seems to be very important for improving the operative results, especially in preoperative patients with conditions such as esophageal carcinoma. in our department, patients who have lost more than 10% of their normal weight have been given intravenous hyperalimentation for at least two weeks preoperatively to prevent postoperative pulmonary complications. however good responses to nutritional support were not always obtained in these ... | 1988 | 3389828 |
| the use of quetol 651 for the post-embedding immunohistochemical demonstration of gamma-aminobutyric acid on semithin sections. | quetol 651 was used as an embedding medium for the demonstration of gamma aminobutyric acid (gaba) in semithin sections by the peroxidase-anti-peroxidase method. in order to demonstrate the immunoreactivity, the embedding medium was partially dissolved using absolute ethanol containing 0.8-1 m naoh or koh for 5-7 min. the experimental procedure was elaborated by testing the gabaergic sites in the endings surrounding the small neurones of the anterior exterolateral nucleus of a mormyrid fish and ... | 1988 | 3209422 |

| [isolation of modified allergens from bee venom]. | to obtain modified bee venom (bv) allergens, covalent binding of bv with previously carboxylated polyethylene glycol (peg) has been used. the conjugation of bv and peg has been achieved by means of carbodiimide. thus 4 kinds of the conjugate with bv/peg ratio ranging from 30:1 to 63:1 have been obtained. the study has shown that chemical treatment in the process of this reaction, dialysis and chromatography does not lead to a decrease in the specific activity of bv, while lyophilization produces ... | 1988 | 3389007 |
| bias current modifies the selectivity of liquid membrane ion-selective microelectrodes. | a negative bias potential of up to -80 mv applied to the back of a liquid membrane ion-selective microelectrode containing classical "k+" ion-exchanger was found to make it more selective for millimolar concentrations of k+ over micromolar concentrations of choline, tetramethylammonium, tetraethylammonium and 5-hydroxytryptamine. conversely, positive bias potential increased severalfold the sensitivity to micromolar concentrations of these ions while decreasing the sensitivity to k+. an increase ... | 1988 | 3380648 |
| isolation of nuclei from melittin-destabilized cells. | melittin, the hydrophobic polypeptide from bee venom, sufficiently destabilizes the plasma membrane of cultured cells to allow cell disruption in the absence of detergents with minimal homogenization. nuclei are thus isolated in high yield with intact nuclear membranes and high transcriptional activity. | 1988 | 3164171 |
