Amanqanaba zentsimbi Low egazini esinxulunyaniswa ne ubuthulu

Xa abantu isiqulatho zentsimbi eliphantsi egazini, oko kunokukhokelela ebizwa ngokuba yi-yentsimbi-imibala anaemia, kuchaphazela impilo jikelele. Uphando lwakutshanje luye lwabonisa ukuba, ukongeza ubuthathaka jikelele, isigulo esinxulunyaniswa lokumamela ongaboniyo.

Imiphumo kwegazi

Uphando olu lwaye lwafumanisa ukuba abadala abaphethwe kwegazi abasengozini yokuba ukuva iingxaki kumaxesha ezimbini ngaphezu esempilweni. Esi sifo ukwabizwa ngokuba ilahleko odityanisiweyo iindlebe.

Unenzondelelo uvavanyo lwezonyango abadala 300,000 ukusuka Pennsylvania. Nxaxheba iminyaka engama-21 ukuya 90, ubudala athetha wayeneminyaka engama-50. Izazinzulu baye bazama ukuba ukhethe kwizigulane zokufunda, bonke abenabo imibala ngentsimbi, bebuva sokunciphisa.

Into esiyaziyo ubuthulu?

Kukho iindidi 3 ukuva ilahleko: sensorineural (okanye labona) ebangela umonakalo kwindlebe engaphakathi, umonakalo luvo, indlebe ezibophelelayo ubuchopho okanye ukuphazamiseka komsebenzi kwengqondo; conductive luphawulwa permeability okulambathayo isandi, nezidibeneyo ubuthulu, edibanisa iimpawu ezimbini ezidlulileyo.

ukuphazamiseka zihlangene

Uphando lufumanise ukuba abantu igazi baba 2.4 amaxesha basengozini indibaniselwano namaxesha 1.8 - ubuthulu sensorineural, xa kuthelekiswa kwabo esi sifo wayengekho. Kodwa ke kwakungekho ulwalamano phakathi ukushiyeka kunye neengxaki zentsimbi kunye ngeendlebe, Isimanga, hayi, ngendlela izazinzulu.

Ingxelo ngeziphumo zeemvavanyo ezidlulileyo phantsi kolwalathiso Kathleen Shniffer, umfundi we-State College of Medicine e Pennsylvania, kwavakala ukuba kukho izizathu ezithile kutheni amanqanaba zentsimbi kunye ubuthulu sensorineural esinxulunyaniswa omnye nomnye.

Ukuphazamiseka neurosensory

ukungeva ukuqonda lunokwenzeka ngenxa yomonakalo ezityeni yegazi encinane indlebe, kunye anaemia kungabangela kanye le nkqubo. Umzekelo, deficiency intsimbi ikhokelela iingxaki kunye nokuhamba kwegazi, nto leyo echaphazela umzimba wonke ngokubanzi, ngoko ke ngokulula kakubi imithambo yegazi nobukhulu encinane. Ukongeza, esi sifo kubangela ukutshatyalaliswa myelin esingxotyeni of luvo, kuquka nezo ukudibanisa iindlebe kunye ingqondo.

Enyanisweni, abaphengululi hypothesized ukuba igazi ukuze ezinxulumene sensorineural ubuthulu, kwaye conductive. Umzekelo, kwi ingxelo ngaphambili kwi isifundo kwalo mba eTaiwan wakhankanya ukuba ukungeva okuqonda ngesiquphe bakwazi ukuphuhlisa kwisithuba seeyure ezingama-72 izigulane deficiency yentsimbi.

ukuphazamisa kwenziwa

Kwelinye icala, conductive ngakumbi kuthiwa iingxaki "zoomatshini", ezifana zengxinano ezindlebeni, ukungena namaqumrhu angaphandle okanye konakalise indlebe. Yiloo nto izazinzulu ziye zacebisa ukuba olu hlobo ubuthulu esinxulunyaniswa igazi.

Kodwa ke, njengoko abaphandi kuphawuliwe, nangona ukuba izigulane ezinochaso amanqanaba asezantsi yentsimbi basengozini yokuva ilahleko, kodwa ngqo elisekwe ubudlelwane phakathi izifo ezimbini. Iimvavanyo zibonakalisa japan engeyizizo, njengoko hayi njengento amaqela ezahlukeneyo ngesondo, enoba unesifo seswekile okanye imikhwa emibi, kwaye musa khangela beempawu uxinzelelo.

Kwixesha elizayo sihlelwe ukuba aqhube isifundo olubanzi ngalo mba. Ekubeni ayoni egazini ndingekawuboni ukumqumbisa ukuva ilahleko, mhlawumbi singama kukuvela ukuva ilahleko izigulane, ukuphelisa iimpawu kwegazi.
