Bilim insanlar\u0131 nadir bir ku\u015f t\u00fcr\u00fc ke\u015ffetti. Papua Yeni Gine’de g\u00f6r\u00fclen “kap\u015fonlu pitohui” d\u00fcnyan\u0131n ilk zehirli ku\u015fu olarak kay\u0131tlara ge\u00e7ti.<\/b><\/p>\n
Zehirli hayvan denilince akla \u00f6r\u00fcmcek, y\u0131lan gibi hayvanlar gelse de ku\u015flar\u0131n da zehirli olabilece\u011fi ara\u015ft\u0131rmalar sonucunda ortaya \u00e7\u0131kt\u0131. Kap\u015fonlu pitohui, bilimsel ara\u015ft\u0131rmalarla do\u011frulanan d\u00fcnyan\u0131n ilk zehirli ku\u015fu oldu.<\/p>\n
Papua Yeni Gine\u2019nin Melanezyal\u0131 halk\u0131, kap\u015fonlu pitohui\u2019nin zehirli oldu\u011funu biliyor olsa da bilim insanlar\u0131 t\u00fcr\u00fcn bu \u00f6zelli\u011finden habersizdi.<\/p>\n
Ancak Jack Dumbacher isimli ara\u015ft\u0131rmac\u0131, zehirli oldu\u011funu, ku\u015fu yakalad\u0131\u011f\u0131nda parma\u011f\u0131n\u0131 gagalad\u0131\u011f\u0131nda anlad\u0131. \u0130\u00e7g\u00fcd\u00fcsel olarak parma\u011f\u0131n\u0131 \u00e7ekti ve ac\u0131y\u0131 dindirmek i\u00e7in a\u011fz\u0131na ald\u0131. H\u0131zla dilini ve dudaklar\u0131n\u0131n uyu\u015fmaya ba\u015flad\u0131\u011f\u0131n\u0131 hissetmeye ard\u0131ndan da a\u011fz\u0131n\u0131n yanmaya ba\u015flad\u0131\u011f\u0131n\u0131 fark etti. Daha sonra semptomlara ku\u015fun neden oldu\u011fundan \u015f\u00fcphelendi.<\/p>\n
Bu hipotezi test etmek i\u00e7in Dumbacher bir pitohui t\u00fcy\u00fc ald\u0131 ve a\u011fz\u0131na yerle\u015ftirdi. Ayn\u0131 uyu\u015fukluk ve ac\u0131y\u0131 hemen a\u011fz\u0131nda hissetmeye ba\u015flad\u0131. Dumbacher b\u00f6lgedeki yerlilere, ku\u015fun ger\u00e7ekten zehirli olup olmad\u0131\u011f\u0131n\u0131 sordu.<\/p>\n
Yeni Gine halk\u0131 pitohui\u2019ye \u201c\u00e7\u00f6p ku\u015fu\u201d diyor \u00e7\u00fcnk\u00fc pi\u015firildi\u011finde \u00e7ok k\u00f6t\u00fc kokuyor ve yaln\u0131zca son \u00e7are olarak t\u00fcketiliyor. Dumbacher, pitohui ve sald\u0131\u011f\u0131 toksin hakk\u0131nda daha fazla \u015fey \u00f6\u011frenmek istedi. Saatlerce \u00e7al\u0131\u015ft\u0131ktan sonra, ku\u015fun t\u00fcylerinde, v\u00fccudunda ve i\u00e7 organlar\u0131nda batrakotoksin depolad\u0131\u011f\u0131n\u0131 belirledi.<\/p>\n
Bu n\u00f6rotoksin, zehirli ok kurba\u011falar\u0131 ve hatta pitohui\u2019nin yedi\u011fi b\u00f6cekler gibi di\u011fer canl\u0131larda bulunuyor. Bilim insanlar\u0131 n\u00f6rotoksini kendisinin \u00fcretti\u011fine inanmad\u0131klar\u0131ndan, bu b\u00f6cekler muhtemelen kap\u015fonlu pitohui\u2019nin zehirli olmas\u0131na neden oluyor. Ku\u015fun v\u00fccudunun bu zehri neden depolad\u0131\u011f\u0131 hala bir s\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
