Kwinxalenye ephezulu yamehlo yomntu ngamnye kukho amadlala. Kufuneka sivelise iinyembezi ezimanzisa amehlo akho kwaye sibakhusela ekulopheni nasekufumaneni intsholongwane eyingozi. Ngelishwa, kwezinye izifo, iinyembezi ziyeka ukuba ziveliswe kwinani elifunekayo kwaye umntu uqala ukomelela emehlweni. Kwaye oku kungqineke zinemvakalelo ebuhlungu kunye nokungaboni kakuhle. Ngokwesiqhelo kule meko, abaguli bayakhuthazwa ngamathontsi akhethekileyo emehlweni, kodwa izazinzulu zifuna ukufunda ukuziphatha ngokupheleleyo izifo zamadlala. Kuyavakala, inye kuphela ingxaki - abaphandi abakwaziyo ngokuthe ngqo, ngenxa yokuba behambahamba ukuba amadlala ayeke ukuvelisa ulwelo. Kodwa kutsha nje, izazinzulu zeNetherlands zakwazi ukudala amadlala akhatywayo ze-lacrimal kwaye kwanyanzela ukuba balile. Kuvakala ngokungaqhelekanga kwaye ukuya kuthi ga kwinqanaba elithile, kodwa kunjalo. Le mpumelelo yesayensi ityhila unobangela wesona sifo siyingozi kakhulu.
Yintoni i-shegreen syndrome?
Esi sifo sibizwa ngokuba yiShegren Syndrome. Iphawulwa ukomiswa kwamehlo kuphela, kodwa kunye ne-mucous midranes yomzimba njengomzimba ofana ne-oral cavity njalo. Into ephakamayo kanye, iSayensi ayiziwa. Inye kuphela into ecacileyo-ngentsimbi ivelisa ulwelo, into ethile yinto engalunganga. Ukufumana unobangela wento engaqhelekanga, izazinzulu zagqiba kwelokuba zenze amagqabi afundwayo kunye nokwenza iimvavanyo ezininzi kuzo. Kananjalo, nabo babenomdla, ukuba kunokwenzeka ukuba baguqulele emehlweni ento ephilayo - ngaba balunge?
I-teatial teage
Ngokweseli yejenali yesayensi, kusetyenziswa iiseli ze-STAL ezineempuku zabantu kunye nabantu, izazinzulu zenze i-organoids ye-organoids ye-tids yeli phepha. Ke obizwa ngokuba yizakhiwo ezinokwenza yonke okanye imisebenzi emiselweyo. Kule meko, sithetha malunga nokuba kunokwenzeka ukuba siziinyembezi. Ukukhula kwelungu elitsha, iiseli ze-stem zasetyenziswa kuba ziyakwazi ukuzimela. Ezi ziindaba-ziphantse zasetyenziswa ekulinywe amalungu emiqolo.
Imbono yaphunyezwa ngempumelelo. Izazinzulu zenze ngokwenene ii-organoids zemigudi yeli dolophana kwaye zinokubenza bakhala. Kule nto, baziveza kwi-norepinephrine - ikhemikhali ezicaphukisayo ukuveliswa kweenyembezi. Ngokutsho kwabaphandi, xa ugcwalisa isakhiwo, isakhiwo sabekwa kwinkani, kwaye ngenxa yoko babevuthelwa kabukhali njengeebhalitini zaze zikhulule.
Uyabona, kutheni iinyembezi zetyiwa kunye noncedo lokujamelana noxinzelelo?
Unyango lwezifo zamehlo
Ke, izazinzulu zikhulise ngempumelelo amadlala anokwazi ukuvelisa iinyembezi. Eyona njongo yokuqala yomsebenzi wesayensi yafezekiswa kwaye i-verting ngowesibini. Kwinxalenye yesibini yomsebenzi, bafuna ukufunda ukuba loluphi uhlobo olunegalelo kuphuhliso lweenyembezi. Ijikakwe ukuba ezona zinto zibalulekileyo kwezi ntlobo ze-pax6 - emva kokususwa kwayo, abaphathi bezenziweyo bema benza umsebenzi wabo ophambili. Ngaphambili, izazinzulu sele zicinge ukuba ezi ntlobo zinokuba netyala kuphuhliso lwe-schreren's syndrome. Ngoku bayazithemba ngakumbi malunga nolu lwazi kwaye olu lwazi luya kubavumela ukuba baphuhlise indlela esebenzayo yonyango lwesifo se-syndrome.
Ukongeza kubo bonke abadweliswe, njengenxalenye yesifundo, izazinzulu zazama ukuhambisa iiseli zenyembezi kwi-gland mice. Ukumangaliswa kwendalo, bayahambelana ngokugqibeleleyo kwaye akudingeki ixesha elininzi. Ngokukodwa, ngokutsalwa kwe-Gland kunye nokuqulwa kwezinto eziyimfuneko zomsebenzi, kwathatha malunga neeveki ezimbini. Kodwa oku akuthethi ukuba amadlala asempilweni anokutshintshelwa kwabanye abantu. Kwithiyori, oku kunokwenzeka, kodwa ngokwenza imisebenzi enjalo ekusebenzeniyo kusekho izifundo ezininzi. Imvume yokwenza olo ungenelelo lotyando luya kunikwa kuphela kwimeko ephumeleleyo.
Ukuba unomdla kwiSayensi neTekhnoloji, bhalisela ijelo lethu kwiYandex.dzen. Apho uya kufumana amanqaku angashicilelwanga kwindawo!
Kufanelekile ukuba uqaphele ukuba ukudalwa kwamalungu abuhlungu yinto eqhelekileyo esele iqhelene neenzululwazi. Ngo-2020, iqabane lam uLiubov Sokovikova laxelela ukuba zendlela izazinzulu zaseTshayina zakwazi ukufumana ngayo iliso. Kwaye yayingumsitho oxoxe kakuhle, kuba eli qumrhu lombono linokubona ebumnyameni kwaye liwahluleke kakuhle oonobumba. Abaphuhlisi babeka phambili ingcinga yokuba kwixa elizayo baya kuba nakho ukuphucula itekhnoloji kunye nabanini bamabhunga afanelekileyo baya kubona ngcono kakhulu kunabantu abaqhelekileyo. Unokufunda ngakumbi ngeliso lokufakelwa kweli khonkco.
