Öğe Comparative cheliceral morphology of the solifuge species Biton zederbaueri (Werner) and Gluviopsilla discolor (Kraepelin) through scanning electron microscopy (Arachnida: Solifugae: Daesiidae)(Max Kasparek Verlag, 2011) Bayram, Abdullah; Yigit, Nazife; Erdek, Melek; Koc, Halil; Sancak, Zafer; Melekoglu, Abdullah; Ocal, Ilkay CorakA detailed comparative morphology of the male chelicerae of Biton zederbaueri (Werner) and Gluviopsilla discolor (Kraepelin) is presented using stereo microscope and scanning electron microscopy (SEM). The morphology of the cheliceral teeth, setae, flagella and some other organs such as the stridulatory organ that are used for description and identification are described and illustrated. The flagella are membranous, but their shapes arc different in both species. The stridulatory organs are similar in both daesiids, being reniform and with seven ridges. On the chelicerae, numerous long-thin, short-thin and short-thick setae are characteristic for both species.Öğe A contribution to the Knowledge of Turkish Jumping Spider Fauna (Araneae: Salticidae)(Inst Zoology, Bas, 2012) Danışman, Tarik; Coşar, İlhan; Erdek, Melek; Sancak, ZaferSeven jumping spider species, Aelurillus gershomi PROSZYN'SKI, 2000, Aelurillus luctuosus (LUCAS, 1846), Chalcoscirtus infimus (SIMON, 1868), Chalcoscirtus tanasevichi MARUSIK, 1991, Euophrys pseudogambosa STRAND, 1915, Pseudicius picaceus (SMON, 1868) and Sitticus avocator (O.

The morphology of the venom apparatus of L. ixobolus using adult spiders that were collected from Kirikkale (Turkey) were investigated by scanning electron microscopy. The general organization of the venom apparatus of L. ixobolus is similar to other spiders' venom apparatus. The venom apparatus, situated in the anterior of the prosoma, is composed of a pair of chelicerae and venom glands. Each chelicera consists of a stout basal and a movable apical (fang) segments. The fang rests in a groove on the basal segment. Both sides of the cheliceral grooves are armed with three marginal teeth. To eject the venom, a venom pore is situated on the subterminal part of the fang. The venom glands of L. ixobolus are equal size and they look like a carrot. Each gland is surrounded by bulky muscular layer. Also, the nerve cells can be easily observed on the surface on the venom gland by Scanning Electron Microscope (SEM). © 2006 Asian Network for Scientific Information.Öğe Functional morphology of the venom apparatus of the funnel spider, Agelena gracilens (Araneae : Agelenidae) from Turkey(Amer Entomol Soc, 2007) Yigit, Nazife; Bayram, Abdullah; Danışman, Tarık; Sancak, ZaferThe funnel-web spider, Agelena gracilens Koch C. L., 1841 is widely distributed throughout Middle Europe, Mediterranean countries, and Middle Asia. The aim of this study is to describe the functional morphology of the venom apparatus in A. gracilens using scanning electron microscopy. The organization of the venom apparatus of A. gracilens follows the general structure of the venom apparatus ofother spiders. The venom apparatus is situated anteriorly in the prosoma and it is composed of a pair of chelicerae and venom glands. Each chelicera consists of a Stout basal and a movable apical (fang) segments. The fang rests in a furrow on the basal segment and it narrows apically. There are parallel fine grooves on the surface ofthe fang. To eject the venom, a venom pore is located on the subterminal part of the fang. The venom glands of A. gracilens are of equal size and tubular. Each gland is Surrounded by a bulky muscular layer. Also, neurons innervate the surface of the venom gland by SEM.Öğe Loxosceles: A Case Healed Completely Without Any Necrotic Tissue by Emergency Department and Review of the Literature(Aves, 2013) Gulalp, Betul; Kayipmaz, Afsin Emre; Altinors, Mehmet Nur; Sancak, Zafer; Yigit, NazifeThe most common finding of Loxosceles biting is a progresive ulcerous dermanecrosis. The responsible dermonecrotic factor found in the venom is Sphingomyelinase D. Poison effects are indicated by coagulation and occlusion which are the initial triggers of tissue necrosis in small capillaries. A 28 year old female patient was admitted after being bitten by a brown spider 3-4 hours earlier while putting on her shoes in the morning. There was a finding wit t a local inflammation on the medial proximal part of the right second toe. The following day, there was a medium grade edema reaching to the ankle, a large lesion colored in red-purple with undetermined borders and increased temperature on palpation. On the first day of hospitalization, RDW was 15.50, WBC was 11.20, neutrophil was 79.80%, lymphocyte was 11.30% on CBC, CRP was 16, CPK was 455, LDH was 78 whereas the parameters of sedimentation, PT, PTT, blood gas were in normal ranges. An x-ray of the foot was taken. Stabilization and elevation of the extremity were provided. She was hospitalized due to Loxosceles poisoning in the Emergency Department for 5 days. The conservative treatment with fluid, antibiotics, corticosteroid, antiinflamatory drugs were initiated. The foot healed with a minimal pigmented dermal finding without any complication of tissue necrosis on the fourth week. The patient without any significant initial complaints and findings in insect bites should not confuse the clinician. The importance of observation of these patients is clear for control of probable complications and misdiagnosis cases.Öğe Loxosceles: A case healed completely without any necrotic tissue by emergency department and review of the literature(2013) Gülalp, Betül; Emre, Afşin Kayıpmaz; Altınörs, Mehmet Nur; Sancak, Zafer; Yiğit, NazifeLoxosceles ısırığında görülen en sık bulgu ısırık yerinde progresif ülsere dermonekrozdur. Sphingomyelinase D zehirdeki asıl dermonekrotik faktördür. Zehir küçük kapillerlerde doku nekrozu başlangıcı olan hızlı koagülasyon ve oklüzyona neden olarak etkisini gösterir. 28 yaşında kadın hasta, sabah ayakkabısını giymeye çalışırken kahverengi bir örümcek tarafından ısırılmasından 3-4 saat sonra kliniğimize başvurdu. Sağ ikinci parmak iç proksimalinde lokal minimal inflamasyondan başka bulgusu yoktu. Ertesi gün gelen hastada ayak bileğine kadar orta derecede ödem, ısırık yerinden başlayarak proksimale ilerleyen sınırları net olmayan palpasyonla ısı artışı ve geniş kırmızı-mor cilt lezyonu mevcuttu. Hospitalizasyonun ilk günü CBCde RDW 15,50, lökosit 11,20, nötrofil %79,80, lenfosit %11,30, CRP 16, ABKda CPK 455, LDH 78, se- dimantasyon, PT, PTZ, kan gazı parametreleri normal sınırlarda idi. Ayak düz filmi çekildi. Ayak stabilizasyon ve elevasyonu sağlandı. Loxosceles zehirlenmesi öntanısıyla Acil Tıp adına 5 gün hospitalize edildi. Hospitalizasyonda sıvı replasmanı, antibiyotik, kortikosteroid, antiinflamatuar ile konservatif tedavi başlandı. Dördüncü hafta hafif pigmente cilt bulgusu dışında doku nekrozuna ait komplikasyon gelişmeksizin iyileşme sağlandı. Böcek sokmaları ile ilk anlarda belirgin bir şikayet ve bulgu olmaması klinisyeni yanıltmamalıdır. Bu hastaların izlemi ve kontrole çağrılmasının ciddi komplikasyonlar ve atlanabi- lecek olgularda önemi açıktır. (JAEM 2013; 12: 101-4)Öğe Morphological characterization of the venom apparatus in the wolf spider Lycosa singoriensis (Laxmann, 1770)(Cevap-Unesp, 2009) Yigit, Nazife; Bayram, Abdullah; Danışman, Tarık; Sancak, Zafer; Tel, M. G.The wolf spider Lycosa singoriensis (Laxmann, 1770) (Lycosidae: Araneae) is distributed throughout central and eastern Europe, including Russia, Kazakhistan and Turkey. This study describes the venom apparatus morphology of L. singoriensis through scanning electron microscopy (SEM). Its structure follows the general architecture observed in other spiders. Generally, a venom apparatus is composed by a pair of venom glands and chelicerae. L. singoriensis chelicerae are robust and consist of a stout basis and a movable apical segment (fang). The fang rests in a groove on the basal segment that is covered by different types of hair. L. singoriensis venom glands present equal size and measure about 4 mm in length. Each gland is enclosed by irregular muscular layers.Öğe New records for the turkish araneo-fauna: theridion varians hahn, 1833, dipoena melanogaster (c. l. koch, 1837) and achaearanea riparia (blackwall, 1834) (araneae: theridiidae)(2007) Bayram, Abdullah; Danışman, Tarık; Yiğit, Nazife; Çorak, İlkay; Sancak, Zafer[No abstract available]Öğe A new species of the genus Hersiliola Thorell, 1870 from Turkey (Araneae: Hersiliidae)(Taylor & Francis Ltd, 2012) Danisman, Tarik; Sancak, Zafer; Erdek, Melek; Cosar, IlhanA new species of Hersiliola Thorell, 1870 is described from Antalya Province, Turkey.

A total of 283 specimens (159 adults and 124 immatures) belong to the Superfamily Argyopiformia (Theridiidae, Nesticidae, Linyphiidae, Araneidae, Metidae, and Tetragnathidae) were examined and identified at species level. In the research region, a total of 41 species and 27 genera belong to above families were found. Hand aspirator, sweeping net and Japanese beating umbrella were used in the collection. The specimens were preserved in the Zoology Research Laboratory of Kırıkkale University.Öğe Venomous spiders of Turkey (Araneae)(2007) Bayram, Abdullah; Kayhan, Nazife Yiğit; Danışman, Tarık; Öcal, İlkay Çorak; Sancak, Zafer; Ulaşoğlu, DeryaOver 50.000 species have been described on the world. Among them about 100 species are dangerous for human. Members of Latrodectus and Loxosceles share the habitats of human beings. Chemically, spider venom is heterogeneous, and contains poly peptide, poly amine, nucleic acid, free amino acid, monoamine, neurotoxin, enzyme and inorganic elements. In enzymes, proteases, hyaluronidase, sphingo-myelinase, phospholipase and isomerase form necrosis. Venom is neurotoxic, and it causes paralysis. In Turkey, some species of Latrodectus, Steatoda, Loxosceles, Cheiracanthium, Segestria, Agelena, Tegenaria, Araneus and Argiope are venomous. The specimens that collected from different habitats and localities of Turkey were examined under stereo microscope. They were identified as species level, and the venom organs of some spiders were investigated morphologically with the light and electron microscope
