Okuphansi yensimbi amazinga egazini lingaphathelaniswa ne ubuthulu

Lapho abantu bethola okuqukethwe yensimbi ongaphakeme egazini, kungaholela okuthiwa yensimbi-ukuntula anaemia, esithinta impilo jikelele. Ucwaningo lwamuva luye lwabonisa ukuthi, ngaphezu nobuthakathaka jikelele, ukugula kungenzeka ukuthi umataniswe bokuzwa ukungakhuli.

Imiphumela anaemia

Lolu cwaningo lwathola ukuthi abantu abadala abaphethwe isifo sokulahlekelwa igazi basengozini okokuzwa izinkinga ngezikhathi ezimbili ezingaphezu kuka enempilo. Lesi sifo ubizwa nangokuthi ukulahlekelwa elihlangene ukuzwa.

Zabhekana ukuhlolwa emitholampilo 300,000 abadala ePennsylvania. Abahlanganyeli engu-21 kuya ku-90, ubudala kusho kwaba iminyaka engu-50. Ososayensi baye bazama ukhethe for iziguli cwaningo, futhi bonke babenethemba yensimbi ukuntuleka kwamavithamini, ukungezwani nokuzwa ngandlela-thile.

Esikwaziyo ukulahlekelwa kukuzwa?

Kukhona 3 imikhakha ukulahlekelwa kukuzwa: sensorineural (noma okuqonda) elibangela ukulimala endlebeni engaphakathi, ukulimala kwenzwa endlebeni esibophezelayo ebuchosheni noma ukuphazamiseka umsebenzi ubuchopho; conductive libhekene permeability abampofu umsindo, futhi kuhlanganiswe ubuthulu, ngokuhlanganisa izici odlule ezimbili.

iziyaluyalu kuhlanganiswe

Abacwaningi bathola ukuthi abantu igazi izikhathi 2.4 usengozini yokuthola inhlanganisela nezikhathi 1.8 - sensorineural ubuthulu, uma kuqhathaniswa nalabo abanale isifo wayengekho. Kodwa kwakungekho ubudlelwano phakathi yensimbi ukuntula nezinkinga izindlebe, Isimanga siwukuthi, cha, ngokososayensi.

Umbiko phezu ukuhlolwa odlule ngaphansi kokuqondisa uKathleen Shniffer, umfundi State College of Medicine e Pennsylvania, kwabikwa ukuthi kwakubulawa kunezizathu ezithile kungani kungenzeka amazinga zensimbi sensorineural ubuthulu ezihlobene nomunye.

ukungakhuli neurosensory

ubuthulu Okuqonda singenzeka ngenxa ukulimala izitsha ezincane igazi indlebe, futhi anaemia kungaba avuse ngokunembile le nqubo. Ngokwesibonelo, yensimbi ukuntula kuholela yezinkinga kwegazi, esithinta umzimba wonke uwonke, ngakho kalula ukulimaza imithambo yegazi yomuntu usayizi encane. Ngaphezu kwalokho, lesi sifo sivame ukubangela ukubhujiswa emgodleni myelin of izinzwa, kuhlanganise nalezo ezingasebenzisi ukuxhuma ezindlebeni nobuchopho.

Eqinisweni, abacwaningi hypothesized ukuba anaemia elihlobene ne sensorineural ubuthulu, hhayi conductive. Ngokwesibonelo, umbiko ngaphambili cwaningo magazini eTaiwan okukhulunywa ukuthi ubuthulu okungazelelwe okuqonda ingaqala emahoreni angama-72 in iziguli yensimbi ukuntula.

thuthuva olwenziwe

Ngakolunye uhlangothi, i-conductive ngaphezulu ibizwa ngokuthi izinkinga "mechanical", ezifana kokuminyaka ezindlebeni, ukungena imizimba angaphandle noma kulimaze eardrum. Yingakho ososayensi baye basikisela ukuthi kungenzeka lolu hlobo ukulahlekelwa ukuzwa ukuthi umataniswe igazi.

Kodwa, njengoba abacwaningi kuqashelwe, naphezu kweqiniso lokuthi iziguli ezine amazinga aphansi nokusansimbi zisengozini ukulahlekelwa kukuzwa, kodwa ubudlelwano phakathi izifo ezimbili ngokunembile aqine. Ukuhlolwa ukukhombisa yi olungalungile, njengoba yayibizwa kanjalo kungabhekwa njengophawu amaqembu ubulili ezahlukene, kungakhathaliseki ukuthi banesifo sikashukela noma imikhuba emibi, futhi musa uhlole ingcindezi izinkomba.

Ngokuzayo sihlelwe azokuqhubela isifundo eningiliziwe ngale ndaba. Njengoba yensimbi ukuntula egazini kungaba empeleni avuse ukulahlekelwa kukuzwa, mhlawumbe singase siyeke okuvela ukulahlekelwa kukuzwa ezigulini, ekuqedeni izimpawu igazi.
