Vitamin D inoda vhitamini A kuitira kuti ive nemhedzisiro inogoneka. Kutora vhitamini A panguva imwechete kunoita kuti vhitamini D ikwire zvakanyanya kupfuura kutora vhitamini D chete. Iko kusanganiswa kwemavhitamini ese ari maviri kwakakwanisawo kuderedza zvakanyanya mazinga ekuzvimba mushure mekurohwa. Kuvandudzwa kwehuropi kwaivewo kuri nani kana mavhitamini ese ari maviri akatorwa.
Vitamin D: Yakakwira bioavailability kuburikidza nevhitamini A
Yagara ichizivikanwa kuti vitamin D inonyanya kutorwa ne magnesium uye vitamin K2. Magnesium inowedzera kushanda kwevhitamini D - uye vhitamini K2 inovimbisa kugovera kwakaringana kwecalcium, iyo, nekuda kwevhitamini D, inogona kutorwa zvakanyanya kubva muura.
Mukuwedzera, zvakaratidzwa kuti kana uchitora vitamini D, munhu anofanirawo kufunga nezvevhitamini A. Inogona kuvandudza vitamin D bioavailability, maererano neongororo yakarongeka, yakarongeka, uye isina-bofu kubva munaAugust 2020 (1). Yakaongorora mhedzisiro yevhitamini A uye vhitamini D mune varwere vakatambura sitiroko.
Stroke inoonekwa semutoro mukuru - kwete kune avo vanobatwa chete asiwo kune yehutano system. Izvi zvinowanzo tungamira mukukuvadzwa kwehuropi kusinga gadzirise, kuremara zvachose, uye matanho ekureba ekudzoreredza.
Sei mavhitaminzi nokuda sitiroko?
Vanhu vachiri kutsvaga mishonga uye maajenti anokurudzira kuvandudzwa mushure mekurohwa uye kuchengetedza kukuvadzwa kwehuropi zvishoma. Mavhitamini nemamineral ari kuwedzera kuuya mukutarisa.
Kurova kwakawanda kunoitika semugumisiro wearteriosclerosis (madhipoziti mutsinga dzeropa / tsinga dzakaomeswa) kana kukonzeresa thrombosis. Kushaikwa kwevhitamini D uye vhitamini A kunowedzera njodzi ye arteriosclerosis uye nekudaro zvakare sitiroko. Izvi zvinotevera zvinoshanda: kuderera kwevhitamini A uye vhitamini D mazinga, iyo yakakura njodzi yekuva nechirwere chemoyo.
Kune rimwe divi, kana iwe ukapihwa zvakanaka nevhitamini A uye vhitamini D, iwo mavhitamini maviri anogona kudzikamisa kukura kwe arteriosclerosis nekuda kweawo anti-inflammatory uye antioxidant mhedzisiro.
Vitamin A mukurohwa
Vitamin A nemametabolites ayo anobatanidzwa mukudzivirira ropa-uropi chinovharira, nokudaro kuderedza kuoma kwekukuvara kunogona kuguma nesitiroko.
Vitamin A receptors inoshandawo padhuze nemamwe ma receptors ane neuroprotective effect, senge. B. ine vhitamini D receptors. Munyaya yevhitamini A uye D, zvinogamuchirwa zvimiro mukati mesero. Iwo mavhitaminzi anoenderana anobata pano uye nekudaro akonzeresa iwo chaiwo maitiro. Iko kubatana ikozvino kunoratidzika sevhitamini A receptors yakagadziriswa neakawanda vhitamini A inosimudzira chiitiko chevhitamini D receptors uye zvinopesana.
Vitamin D mukurohwa
Chidzidzo che 2015 chevarwere ve818 chakaratidza kuti avo vane mazinga epamusoro evhitamini D vakapona sitiroko yavo zviri nani pane avo vane mazinga akaderera evhitamini D. Vitamin D mazinga anogona saka kushandiswa kwete chete sechiratidzo chechirwere chemoyo njodzi uye kufa asiwo nekupona sitiroko.
Muna 2017, takashuma nezvechidzidzo (Vitamin D Repairs Blood Vessels Pakarepo) umo vatori vechikamu vakanga vatoratidza zviratidzo zvekuoma kwetsinga vakatora 4,000 IU yevhitamini D zuva nezuva. After 4 months kuoma kwetsinga kwainge kwadzikira. Chinyorwa chakabatanidzwa chinotsanangura nzira dzinoverengeka iyo vhitamini inodzivirira tsinga.
Chidzidzo: Kuti vhitamini A uye vhitamini D zvinosimbisana sei
Muchidzidzo chaNyamavhuvhu 2020 chakataurwa pakutanga, varwere vesitiroko 120 vakatora chikamu. Vese vaive varwara neacute ischemic stroke uye vakaonekwa mukati memazuva matatu. Vakarapwa nemishonga yakajairika uye vakagamuchira kurapwa kwemuviri.
Ischemic sitiroko inoitika semugumisiro wearteriosclerosis kana thrombosis, kureva nekuda kwemudziyo wakavharwa weropa uye kwete - sechiitiko chehemorrhagic sitiroko - nekuda kwecerebral hemorrhage. Mazhinji sitiroko ane ischemic mune zvakasikwa.
Ko Mavhitamini Anobatsira NeStroke Rehab?
Kuti uone kana uye kuti mavhitamini A uye D anoshanda sei mukupora sitiroko, vatori vechikamu muchidzidzo ichi vakakamurwa kuita mapoka mana:
- Boka revhitamini A rakagamuchira 50,000 IU (= 15 mg) yevhitamini A kamwe pavhiki (yakaenzana ne90 mg ye beta carotene)
- Boka revhitamini D rakagamuchira 50,000 IU (= 1250 µg) yevhitamini D3 kamwe pavhiki.
- Boka rakabatanidzwa rakagamuchira 50,000 IU imwe neimwe yevhitamini A uye vitamini D3 kamwe chete pavhiki
- Boka replacebo rakagamuchira gadziriro ye placebo kamwe pasvondo
Mushonga wega wega wakatorwa kwemavhiki gumi nemaviri. Pakutanga kwekudzidza - kureva panguva yekuongororwa kwesitiroko uye mavhithamini asati atorwa - chiyero chevhitamini D chisina kukwana chakawanikwa kune varwere vose (avhareji 12 ng / ml). Avhareji yevhitamini A level, kune rumwe rutivi, yaive yakajairika (20.75 μg/l).
Mushure memwedzi mitatu, zvinotevera zvakawanikwa:
Vitamin D inokurudzira kutorwa kwevhitamini A
Muboka revhitamini A uye muboka rakabatanidzwa, mwero wevhitamini A wakanga wawedzera. Mamwe mapoka maviri haana (havana kutora vhitamini zvakare).
Muboka rakabatanidzwa, huwandu hwevhitamini A hwakakwira zvakanyanya kupfuura muboka revhitamini A, zvichiratidza kuti vhitamini D inokurudzira kutorwa kwevhitamini A.
Muboka revhitamini A, chiyero chakasimuka kubva pa476 kusvika ku498 µg/l, uye muboka rakabatanidzwa kubva pa462 kusvika ku511 μg/l.
Vitamin A inokurudzira kutorwa kwevhitamini D
Muboka revhitamini D uye muboka rakabatanidzwa, chiyero chevhitamini D chakanga chawedzera zvakanyanya. Mune mamwe mapoka maviri, yakanga yadonha zvishoma.
Vitamin D mazinga akawedzera ne12 muzana pamavhiki e12 apo vitamini D yakatorwa yoga, nepo yakawedzera ne30 muzana apo mavhitamini ose maviri akatorwa pamwechete. Saka vhitamini D haingosimudziri kubatwa kwevhitamini D. Izvo zvakare imwe nzira yakapoteredza: vhitamini A inokurudzirawo kubatwa kwevhitamini D.
Kusanganiswa kwevhitamini kunoderedza kuzvimba zvakanyanya
Arteriosclerosis inogara ichiperekedzwa nekusingaperi kuzvimba maitiro, ayo anogona kutsanangurwa nekuwedzera mazinga eiyo pro-inflammatory messenger zvinhu. Interleukin-1β (IL-1β) inhume inoputika iyo inoshandiswa sechiratidzo che arteriosclerosis. Iyo yakakwirira yeIL-1β kukosha, iyo inonyanya kutaurwa iyo arteriosclerosis uye inowedzera njodzi yesitiroko.
Iyo inoputika messenger interleukin-1 (IL-1) haigoni kuonekwa muhutano hwehutano; chete kana paine kukuvara kwehuropi nekuda kwehurwere (semuenzaniso sitiroko). Vitamin D ndechimwe chezviya zvinovaka muviri zvinoita basa rakakosha musitiroko nekuti vhitamini inodzika-inogadzirisa kuzvimba, semuenzaniso nezve pesvedzero yayo painterleukin.
Muchidzidzo chiri pamusoro apa, chiyero che IL-1β chakangoderera muboka revhitamini D uye muboka rakabatanidzwa. Muboka revhitamini D, yakawira kubva ku0.3 kusvika ku0.27 pg / ml, muboka rakabatanidzwa yakawira zvakanyanya, iyo kubva ku0.49 kusvika ku0.21 pg / ml.
Muboka revhitamini A, kune rumwe rutivi, yakasimuka zvishoma kubva ku0.47 kusvika ku0.49 pg/ml. Muboka re placebo, yakawedzera zvakanyanya kubva ku0.43 kusvika ku0.79 pg/ml.
Vitamin A saka inoratidzika kunge inotsigira zvakajeka anti-kuzvimba mhedzisiro yevhitamini D pano, kunyangwe yaive isina inopindirana mhedzisiro pachayo.
Vitamin Musanganiswa: Yakanakisa Stroke Kudzoreredza
National Institutes of Health Stroke Scale (NIHSS) inogona kushandiswa kuongorora kuoma kwesitiroko. Chikero ichi chine mazinga mashanu:
- 0 hapana zviratidzo zvesitiroko
- 1-4 zviratidzo zviduku
- 5-15 zviratidzo zvine mwero
- 16-20 zviri pakati nepakati kusvika kune zvakanyanya zviratidzo
- 21 - 42 zviratidzo zvakasimba
Muchidzidzo chezvino, mucherechedzo weNIHSS wakawa zvakanyanya muboka rakabatanidzwa, zvichiratidza kuti kupa mavhitamini ese ari maviri panguva yesitiroko ndiyo nzira yakanakisa yekuita uye ine mhedzisiro yakanaka. Detailed results was sezvizvi:
- Vitamin A: NIHSS kukosha inodonha kubva 12.1 kusvika 10.3
- Vitamin D: NIHSS kukosha kunodonha kubva 13.2 kusvika 10.4
- Vitamin A uye D: NIHSS kukosha inodonha kubva 13.25 kusvika 6
- Placebo: NIHSS mamakisi anodonha kubva 13.15 kusvika 11.75
Vitamin D inoshanda zvakakwana nevhitamini A
Mushonga wakakwana wevhitamini D unoratidzika kunge unogoneka chete kana paine vhitamini A. Masayendisiti anonyora kuti:
Kusanganiswa kwevhitamini A uye D kunoderedza arteriosclerosis
Sezvo IL-1β ichionekwa sechiratidzo chekuvandudzwa kwearteriosclerosis uye kukosha uku kwakawira muchidzidzo chazvino, vaongorori vanonyora kuti: "Zvatinowana zvinoratidza kuti kutonga panguva imwe chete yevhitamini D uye vhitamini A synergistically (kuwirirana kusimbisa) kunoderedza arteriosclerosis uye inodzivirira vascular masvingo nekudzivisa oxidative kusagadzikana uye kuzvimba. Kubata kwakabatanidzwa kwemavhitamini maviri, saka, nzira inovimbisa mukurapa nekudzivirira arteriosclerosis. "
Mhedziso: Vitamin D inotorwa zvakanyanya nevhitamini A
Kuenzaniswa nevapukunyuki vesitiroko vanongogashira kurapwa kwezvinodhaka uye kurapwa kwemuviri, vanopona sitiroko vanowanawo mavhitamini A uye D vanopora zvirinani.
Iyo yakawanda yevhitamini A yakataurwa pamusoro apa haidiwi pakudzivirira kana kugoverwa kwezuva nezuva kwevhitamini D. Iyo inowanzokurudzirwa zuva rega rega yevhitamini A ye 1 mg yakakwana.
Mune matipi edu ekugadzirisa vhitamini D yako yekugovera, iwe unowana ruzivo rwese rwaunoda kudzivirira kukanganisa kana uchitora vhitamini D.
Mavhitaminzi Akakwana Kudzivirira Sroke?
Chokwadika, kutora mavhitamini chete hakugoni kuva nechokwadi chokuti sitiroko inodziviswa kana kuti sitiroko yakaitika inogona kukundwa nyore nyore. Zvimwe zvinhu zvakawanda zvinopesvedzera njodzi yearteriosclerosis uye sitiroko pamwe nekufamba kwekuvandudza mushure mekurohwa, semuenzaniso B. bumbiro remutemo, kudya kunovaka muviri, kudzidziswa kwemuviri, nezvimwewo. Nguva dzose funga zvakakwana uye batanidza matanho ekudzivirira akawanda mukudzivirira kwako kana kurapa pfungwa. sezvinobvira.
