| studies on the anticonvulsive, sedative and hypothermic effects of periostracum cicadae extracts. | the anticonvulsive, sedative and hypothermic effects of water and ethanol extracts of periostracum cicadae (pc), the cast off skin of cryptotympana atrata were studied. the water-extract of whole periostracum cicadae (pcws) had anticonvulsive, sedative and hypothermic effects in rats. orally, it decreased carrageenin-induced hyperthermia. the hypothermic effect of pcws was potentiated by 5-hydroxytryptophan and antagonized by p-chlorophenylalanine. pcws enhanced the decrease in locomotor activit ... | 1991 | 1753798 |
| [immunologic inhibition and anti-allergic action of cryptotympana atrata fabricius]. | cryptoympana atrata fabricius(caf)ig 5g/kg in mice decreases weights of the spleen and thymus, markedly decreases the clearance rate of iv charcoal particles and significantly inhibits the phagocytosis of peritoneal macrophages of mice. caf ig at the above doses markedly suppresses ige antibody mediated reactions, heterologous passive cutaneous anaphylaxis (pca) in mice, degranulation of mast cells of calvarial periosteum in rats, and the delayed hypersensitivity reaction of ear induced by dncb ... | 1989 | 2508674 |
| preparation of chitooligosaccharides from cicada slough and their antibacterial activity. | in this study, chitooligosaccharides were prepared from cicada slough of cryptotympana atrata fabricius by hydrolysis using hydrogen peroxide (h2o2). factors affecting the hydrolysis of chitosan were investigated and the optimum hydrolysis conditions were as follows: time, 4 h; temperature, 65 °c; amount of h2o2, 2% (v/v); and ph, 5. under these conditions, the average degree of polymerisation decreased to ~4.5. the fourier transform infrared spectra and product sugar composition indicate that t ... | 2013 | 24095661 |
| characterizations of a new cordyceps cicadae isolate and production of adenosine and cordycepin. | cordyceps is a fastidious pathogenic fungus infecting insects, and recent years have witnessed rapid progress in its medical properties. in this study, a wild isolate, c. cicadae mp12, was characterized through in vitro cultivation and its nuclear small-subunit (ssu) ribosomal dna (rdna) data. in vitro culture of c. cicadae mp12 was established by growing its fruiting bodies in a solid matrix. c. cicadae mp12 was inoculated into cryptotympana atrata cicada pupae for in vivo culture, where the fu ... | 2012 | 24031851 |
| total and methyl mercury contents and distribution characteristics in cicada, cryptotympana atrata (fabricius). | total and methyl mercury concentrations of cicada bodies, wings, and exuviae were investigated to study the mercury distribution characteristics. results indicated that total and methyl mercury concentrations of cicada bodies were 2.64 mg/kg and 123.93 ng/g on average, respectively. in cicada tissues, total mercury concentrations were found to increase in the order of exuviae (0.50 mg/kg on average) < wings (0.98 mg/kg on average) < cicada bodies (2.64 mg/kg on average) and methyl mercury concen ... | 2010 | 20467725 |
| influence of cuticle nanostructuring on the wetting behaviour/states on cicada wings. | the nanoscale protrusions of different morphologies on wing surfaces of four cicada species were examined under an environmental scanning electron microscope (esem). the water contact angles (cas) of the wing surfaces were measured along with droplet adhesion values using a high-sensitivity microelectromechanical balance system. the water ca and adhesive force measurements obtained were found to relate to the nanostructuring differences of the four species. the adhesive forces in combination wit ... | 2012 | 22536351 |
| identifying core herbal treatments for urticaria using taiwan's nationwide prescription database. | urticaria is a common skin disease that has a high impact on a patient's daily life. chinese herbal medicine (chm) has been frequently used for treatment of skin manifestations in addition to western medicine. the aim of this study is to analyze a nationwide prescription database to explore the most commonly used chm for urticaria. | 2013 | 23684721 |
| anti-inflammatory effects of cryptotympana atrata fabricius slough shed on contact dermatitis induced by dinitrofluorobenzene in mice. | the slough shed of cryptotympana atrata fabricius is widely used to treat skin diseases in china, japan, and korea. | 2014 | 24991117 |
| morphology and identification of the final instar nymphs of three cicadas (hemiptera, cicadidae) in guanzhong plain, china based on comparative morphometrics. | the present investigation provides comparative morphometrics of the final instar nymphs of three dominant cicada species, i.e., cryptotympana atrata (fabricius), meimuna mongolica (distant) and platypleura kaempferi (fabricius), in guanzhong plain, china. particularly, characters on the antennae, legs, and apex of abdomen of both males and females of these three species were investigated and analyzed. in addition, the numbers of hind tibial spines of the final instar nymphs of 21 representatives ... | 2014 | 25147447 |
| rapid fabrication of bio-inspired nanostructure with hydrophobicity and antireflectivity on polystyrene surface replicating from cicada wings. | the fine nanostructure on the cicada wing of cryptotympana atrata fabricius, which exhibits hydrophobicity and antireflectivity, is carefully examined. a promising strategy is proposed for facilely and successively replicating the natural functional nanostructure of the cicada wing onto polystyrene (ps) surfaces. first, a nickel replica with tapered nanopores is fabricated by combining electroless plating and subsequent electroplating with the natural cicada wing as an original template. then, u ... | 2017 | 28792045 |
| urban heat island effect on cicada densities in metropolitan seoul. | urban heat island (uhi) effect, the ubiquitous consequence of urbanization, is considered to play a major role in population expansion of numerous insects. cryptotympana atrata and hyalessa fuscata are the most abundant cicada species in the korean peninsula, where their population densities are higher in urban than in rural areas. we predicted a positive relationship between the uhi intensities and population densities of these two cicada species in metropolitan seoul. | 2018 | 29340243 |
| effect of cryptotympana atrata extract on compound 48/80-induced anaphylactic reactions. | we studied the effect of the aqueous extract of cryptotympana atrata fabricius on anaphylactic reactions. cryptotympana atrata completely inhibited compound 48/80-induced systemic anaphylactic shock at doses of 0.5 and 1.0 g/kg. when cryptotympana atrata was given as pretreatment at concentrations ranging from 0.025 to 1.0 g/kg, the plasma histamine levels induced by compound 48/80 were reduced in a dose-dependent manner. cryptotympana atrata also inhibited histamine release from rat peritoneal ... | 1999 | 10473179 |
