Multiple sclerosis: Pamwe haisi vhitamini D kubva kuzuva inobatsira vanhu vane multiple sclerosis, asi UVB mwaranzi.
Ndizvozvo ... iwo mwaranzi imwe chete inokonzera gomarara reganda.
Helen Tremlett, PhD, purofesa we neuroepidemiology uye multiple sclerosis paDjavad Mowafaghian Center yeBrain Health, akadzidza kusvibiswa kwezuva pamusoro pehupenyu hwevarwere vane multiple sclerosis vachishandisa ruzivo rwekucheka-kumucheto. kubva kuNASA.
Kubva kuNurses' Health Study cohort, vanhu zviuru zvitatu nemazana maviri nemakumi maviri nevatanhatu vane multiple sclerosis (MS) vakaiswa geocoded.
Ruzivo urwu rwakabva rwaenzaniswa nekuongororwa neNASA UVB yekutevera data.
Tremlett nechikwata chake vakaenda kuBoston zvakanangana neboka reNurses 'Health Study.
“Kuongorora mhando dzemibvunzo iyi chinhu chikuru uye chine simba. Vaitevera vakadzi vaiva vanamukoti muUnited States. Nekufamba kwenguva, vamwe vakatanga zvirwere zvakaita seMS,” Tremlett akaudza Healthline.
Avo vaigara munzvimbo dzine UVB yakakwirira vaiva ne45% yakaderedzwa ngozi yeMS. Kuratidzwa kwezuva rakakwirira rezhizha munzvimbo dzakakwirira dzeUVB kwaibatanidzawo nenjodzi yakadzikira.
"Vanhu vaisada ganda rakawanda, kungove kunze muzuva," akadaro Tremlett.
Muviri unogadzira vhitamini D kana waiswa muchiedza chezuva. Zvisinei, chidzidzo chacho chinoratidza kuti pane zvinopfuura vitamini D pakutamba pano.
"Hatizive kuti zvinoshanda sei," akadaro Tremlett. "Zvinogona kunge, semuenzaniso, kuti zuva rinorova retina kuseri kweziso, izvo zvinokanganisa huwandu hwe melatonin inogadzirwa, iyo inokanganisa circadian rhythm. Izvi zvinogona kukanganisa kutenderera kwekurara-kumuka uye mutemo wekudzivirira muviri, ”Tremlett akadaro.

Chimwe chidzidzo chezuva
Imwe chirongwa chekutsvagisa, iyo Sunshine Study, yakaongorora kuratidzwa kwezuva kwehupenyu hwese uye hukama hwayo neMS.
Pamusoro pezvo, chidzidzo ichi chakaongorora mazinga evhitamini D uye akakamura nyaya uye zvidzoro kuva Caucasians uye vanhu veAfrica neHispanic.
Mhosva uye cheki dzakatorwa nenhengo dzeKaiser Permanente Southern California.
Zvidzidzo zvakawanda zvakanyora hukama pakati pevhitamini D neMS. Asi chidzidzo ichi chinobvunza mubvunzo vitamin D sechikonzero cheMS uye basa rayo mukuvandudza hutano, kunyanya kuvanhu veAfrica neHispanic.
Yakakwira vhitamini D yaisanganiswa nenjodzi yakaderera yemultiple sclerosis chete muvanhu vachena, kwete muvanhu veAfrica neHispanic. Pakanga pasina kubatana kune mamwe mapoka madiki.
Izvo zvakare zvakasimbiswa kuti kuratidzwa kwehupenyu hwese kunoratidzika kunoderedza njodzi yeMS, zvisinei nedzinza kana dzinza.
“Vanhu vanopedza nguva yakawanda vari panze vanowanzoita zvemitambo sekufamba, kukwira makomo, kuchovha bhasikoro, kumhanya kana kurima. Saka kungava kusanganiswa kwekurovedza muviri kwekunze kunodzivirira chaizvo vanhu kubva kuMS, "akadaro Dr. Annette Langer-Gould, mubatsiri paKaiser Permanente Southern California muPasadena, nhengo yeAmerican Academy of Neurology. uye munyori wekudzidza.
Mavhitamini D mazinga inzira iri nyore yekuyera izvi zvisina kunanga muCaucasus, asi kwete muvanhu veHispanic kana veAfrica, avo vane vhitamini D mazinga haasimuke zvakanyanya kunyangwe aine zuva rakafanana.
"Kurudziro yangu ndeyekuwana chiedza chezuva kubva kune zvakasikwa, kupfeka sunscreen kudzivirira gomarara reganda, uye kuedza kupedza avhareji yemaminitsi makumi matatu pazuva uchiita mabasa ekunze sekufamba kana kurima," Langer-Gould akaudza Healthline.
"Ine chimwe chinhu chine chokuita nehutachiona hwehutachiona, masero ekugadzirisa anowedzera ultraviolet," akatsanangura kudaro Nick LaRocca, PhD, mutevedzeri wemutungamiri wehutano hwehutano uye tsvakurudzo yemitemo paNational Multiple Sclerosis Society.
"Kune kufarira kuri kukura kwekuti UV mwaranzi inoita basa muMS njodzi, yakazvimirira nebasa revhitamini D," akaudza Healthline.
Zvidzidzo izvi zvakatarisa kwakakurira vanhu uye kubatana kuMS.
Kudzidza kunotanga muAustralia
Gore rakapera, Prue Hart, Ph.D., wekuWestern Australia, akabudirira kushandisa mwaranzi yeUV pavarwere vemultiple sclerosis vakamborwiswa asi vasina chimwe chiitiko chechirwere.
Mushure memhedzisiro yakanaka, Hart akabva agadzira muyedzo wePhoCIS kuti uenderere mberi nekudzidza mhedzisiro yemwaranzi yeUV (phototherapy) pane varwere veMS vane kliniki isolated syndrome (CIS).
Ichi chidzidzo parizvino chiri kutorwa.
"Kana basa rechiedza chezuva rakanyanya kuoma kupfuura zvanga zvichitarisirwa, tinoda kuziva," akadaro LaRocca, achiwedzera kuti "kune chero chinhu chine chekuita nemultiple sclerosis, chakaoma."
