slow and spike potentials recorded from retinula cells of the honeybee drone in response to light.responses to light recorded by means of intracellular microelectrodes in isolated heads kept in oxygenated ringer solution consist of a slow depolarization. light adaptation increases the rates of depolarization and repolarization and decreases the amplitude of the response. qualitatively these changes are similar to those observed in limulus by fuortes and hodgkin. they are rapidly reversible during dark adaptation. in retinula cells of the drone eye a large single spike is recorded superimpose ...19685722083

effects of sodium, potassium, and calcium ions on slow and spike potentials in single photoreceptor cells.the influence of changes in the ionic composition of the bathing medium on responses of the retinula cell of the honeybee drone to light was examined by means of intracellular microelectrodes. the resting potential of the cell was influenced mainly by the concentration of k. the peak of the receptor potential (the transient), which in a normal solution and with strong light approaches zero membrane potential, overshot this level in a k-rich solution. an increase in the concentration of k also ra ...19695769421
honey bee recruitment to food sources: olfaction or language?honey bee recruits locate food sources by olfaction and not by use of distance and direction information contained in the recruitment dance. recruitment efficiency increases as odor of the food source accumulates in the hive, from hour to hour and from day to day. flight patterns, landing patterns, bee odor, and nassanoff secretion apparently do not aid in recruitment of bees.19695773718
brood care in halictine bees.four species of the halictine bee genus evylaeus keep their brood cells open during most or part of the development of the larvae. in the colonial summer phase, house bees care for the young and keep brood cells clean from feces and exuviae. progressive feeding of nector is present at least in evylaeus malachurus, whose fully fed larvae are, on an average, 60 percent heavier than the egg-and-pollen stage. interactions between the two generations of social halictinae are of general occurrence, an ...19695777212

hyaluronidase polymorphism detected by polyacrylamide gel electrophoresis. application to hyaluronidases from bacteria, slime molds, bee and snake venoms, bovine testes, rat liver lysosomes, and human serum.a gel electrophoretic technique which allows detection of hyaluronidase activity in the gel has been devised. the principle is that the high-molecular-weight substrate, hyaluronic acid, is included in the gel, where it cannot move in the electrical field. after the run, the gel is incubated under conditions allowing the enzyme to degrade the substrate. upon staining with "stains-all" dye (eastman kodak co., 2718), zones of hyaluronidase activity appear as pink bands in a blue background. the sen ...19846084966
spiroplasmas of group i: the spiroplasma citri cluster.we propose that group i spiroplasmas be subdivided into seven, rather than four, subgroups. the seven subgroups showed remarkable homogeneity when several representative strains were compared. hybridization reactions between dnas of representative strains within subgroups were generally at least 90 percent, and usually at least 80 percent co-migrating cell proteins were found. in addition, when plasmid dna was excluded, profiles of restricted dna among strains within subgroups were very similar. ...19836089454
neurotensin receptors on the ileum of the guinea-pig: evidence for the coexistence of inhibitory and excitatory receptors.neurotensin caused a complex muscular response of the longitudinal muscle-myenteric plexus preparation of guinea-pig ileum: picomoles of neurotensin produced inhibition while larger concentrations caused an inhibitory effect followed by a delayed dose-dependent contraction. the inhibitory phase of the neurotensin-induced muscular activity was not modified by tetrodotoxin but was potently antagonized in a non-competitive manner by apamin, a bee venom toxin. the contractile component was blocked b ...19846090161
[interaction of tertiapin, a neurotoxin from bee venom, with calmodulin].tertiapin, a neurotoxin from the honey bee venom, interacts specifically with calmodulin in the presence of ca2+. the nature of this interaction was studied using calmodulin-camp phosphodiesterase system. tertiapin does not affect the unstimulated basal activity of phosphodiesterase. however, it totally inhibits the enzyme-activating capacity of calmodulin. analysis of the dose-dependent activation of phosphodiesterase by calmodulin in the presence of tertiapin indicated that inhibition is cause ...19836091685
arachidonic acid, 12- and 15-hydroxyeicosatetraenoic acids, eicosapentaenoic acid, and phospholipase a2 induce starfish oocyte maturation.in starfish oocyte maturation (meiosis reinitiation) is induced by the natural hormone 1-methyladenine (1-me-ade). this paper shows that arachidonic acid (aa) induces oocyte maturation at concentrations above 0.5 microm. this maturation shares many characteristics with 1-meade-induced maturation: same kinetics, same required contact time, same stimulations of protein phosphorylation and sodium influx. although calcium facilitates the aa-induced but not the 1-meade-induced maturation, aa, like 1- ...19846094288
the presence in pig brain of an endogenous equivalent of apamin, the bee venom peptide that specifically blocks ca2+-dependent k+ channels.an apamin-like factor has been isolated from pig brain after extraction of the tissue and purification on sulfopropyl-sephadex c-25 and on reversed-phase high pressure liquid chromatography. the apamin-like factor has the following properties: (i) it prevents 125i-labeled apamin binding to its specific receptor site present on rat brain synaptosomes, (ii) it is active in the radioimmunoassay for apamin (i.e., it prevents 125i-labeled apamin precipitation by anti-apamin antibodies), (iii) it indu ...19846095277
research in the field of antiviral chemotherapy performed in the "stefan s. nicolau" institute of virology.a brief review is made of the research in the field of antiviral chemotherapy performed in the "stefan s. nicolau" institute of virology during the 35 years since its foundation. the investigations have mainly focused on influenza and herpes virus, but the chemotherapy of other viral infections (mumps, vaccinia, coxsackie, etc.) has also been approached. most of the chemotherapy agents assayed have been represented by natural preparations: immunoglobulins, interferon, hormones, vitamins, plant e ...19846097022
bee venom inhibits superoxide production by human neutrophils.investigation of the antiinflammatory properties of bee venom demonstrates that it inhibits production of superoxide anion by human neutrophils in a potent, selective, nontoxic, dose-dependent fashion, both pre- and poststimulation by particulate and soluble activators of the neutrophil oxidative metabolism burst. the effect is not due to receptor competition, superoxide dismutase, and/or catalase activity, scavenging, or indicator media effects. these findings may explain the antiinflammatory e ...19846097547
effects of apamin on the outward potassium current of isolated frog skeletal muscle fibres.the effect of apamin, a polypeptidic toxin from bee venom which is a specific blocker of certain ca2+-dependent k+ channels, has been tested (50-100nm) on voltage clamped single skeletal muscle fibres of the frog. the results have shown the existence of an inhibitory effect of the toxin on the slow outward k+ current which suggests the existence of a ca2+-sensitive component of the slow k+ permeability in the plasma membrane of the frog muscle fibre.19846098894
apamin: a specific toxin to study a class of ca2+-dependent k+ channels.apamin is a bee venom neurotoxin of 18 amino-acids containing two disulfide bridges. current clamp and voltage clamp experiments have shown that externally applied apamin blocks specifically at low concentration (0.1 microm) the ca2+-dependent slow k+ conductance which mediates the long-lasting after-hyperpolarization in neuroblastoma cells and rat muscle cells in culture. the apamin-sensitive ca2+-dependent slow k+ conductance is voltage-dependent and tetraethylammonium (tea) insensitive. it is ...19846099412
