Cilmi isku dayayaan si aad u ogaato sababta cir soo celi Earth aragti cawlan

Cosmonauts iyo cir qabashada muddo dheer on saldhigyada orbital, in kiisaska intooda badan ku soo laabtay Earth ka riyada ku dhacday. Ilaa iyo hadda, saynisyahano ayaan ogaan karin sababta this ifafaale, taas oo macnaheedu yahay in halis - caafimaadka dadka kuwaas oo isku diyaarinaya qabsashadii of meel dibadda ah mustaqbalka. Malaha, hadda bulshada sayniska waxaa jiray wax fikrad ah in ay ifafaale ka.

About 80 boqolkiiba sii daraysa ee cir

Cilmi baadhayaasha Jaamacadda Miami helay sababta keenta in khasaare qayb ka mid ah aragtida. Sida ay sheegayaan qiyaasaha kala duwan, caafimaadka sii xumaanaya ee isha back to Earth ku saabsan 80 boqolkiiba sahamiyayaal bannaan. Qaar badan oo iyaga ka mid ah baa dhici view Ulasocto hypertension intracranial. Si kastaba ha ahaatee, saynisyahano ka Miami aan diyaar u ahaayeen in si toos ah link labada ifafaale inta ay ma jiraan wax fikrad ah. Horaantii, wararka la isla dhexmarayo ayaa la sameeyay in bulshada sayniska in dareeraha in aanu miisaan aan la qaybiyaa karo by jidhka sida ay qabato on Earth. Waxa ay u muuqataa in fikradahaaga waxay leeyihiin sal dhab ah.

Maxaa sababa cadaadis isha?

author Lead Noam Alperin ayaa sheegay in xaaladaha khatarta on Earth cuf-galayn walxaha dareere hoos jidhka. Si kastaba ha ahaatee, in xaaladaha aanu miisaan arkay socdaalka dheecaan dhinaca ka soo horjeeda (madaxa). socodka dareeraha maskaxda sababa cadaadis intracranial soo kordha iyo qeybiyey aaga saldhigyadii dhirfinaya la kordhiyo cadaadiska intraocular. cir Most qabashada miisaan jirin muddo bilo ah, ku soo laabtay Earth la astigmatism. Nasiib darro, in kiisaska intooda badan, cudurka this waxay leedahay cawaaqib karin. In si kale loo dhigo, aragtida cir sii darto inta ka hartay noloshaada.

Seynisyahanno xoogga saaraan in this ifafaale waa soo jireenka ah oo kaliya in ay kuwa lagu qasbay in ay sii saldhigga meel bannaan oo muddo dheer. Dr. Alperin ayaa sheegay in sii daraysa ee cir ku hawlan on duulimaad gaaban, waxaa laga soo minguuriyay.

baaritaan faahfaahsan

In view of kooxda cilmi aan ku jiray oo dhan dheecaannada jidhka. Seynisyahanno ka Miami horrayn xiiso dheecaanka lafdhabarka. walax Tan waxaa loogu tala galay in ay maskaxda iyo xangulada ka gariirka iyo shoog ilaaliyo. qeybiyey ee mugga dareeraha ah in ay saldhig isha dhirfinaya sii daraysa ee aragtida (contours ee walxaha noqon haydh iyo isku darsamay). Loogasoo ee ventricle ah lafdhabarka dheecaan keeni cadaadiska intracranial. Waxaa xusid mudan in unugyada aad oo ka mid ah xubnaha gudaha ee isbedeladan la aqoonsaday.

hababka Search difaaca

Natiijooyinka daraasadda waxaa lagu soo bandhigay kulanka sannadlaha ah ee Society shucaaca ee North America ee Chicago. Sida laga soo xigtay saynisyahano, haatan shaaca ka qaaday sababta sii daraysa ee cir ah, waxay ka caawisaa in ay raadiyaan habab ka mid ah xaaladda. khubarada NASA ayaa xiiso u helo xal sida ugu dhakhsaha badan ee suurtogalka ah. Si taas loo gaaro, hay'adda boos shaqaalaha ayaa qorshaynaysa in ay cilinta xaaladaha aanu miisaan on Earth, iyo cilmi baaris dheeraad ah.
