"Chinhu chose chinokura nechiedza chezuva", chiedza chezuva chine chiedza chakasiyana-siyana, chimwe nechimwe chine urefu hwemarefu hwakasiyana, chinoratidza ruvara rwakasiyana, nekuda kwekupenya kwaro kwehudzamu hwenyama uye nzira dzekuongorora mifananidzo dzakasiyana, mhedzisiro pamuviri wemunhu yakasiyanawo.
Purofesa weHarvard Medical School, Michael Hamblin, akaburitsa zvinyorwa zvekutsvagisa zvinoratidza kuti chiedza chitsvuku chinogona kuburitsa mhedzisiro yekupisa, mhedzisiro ye photochemical, uye zvimwe zviitiko zvehupenyu, uye kudzika kwekupinda kwenyama dzemunhu kusvika 30mm kana kupfuura, zvakananga pamidziyo yeropa, midziyo ye lymphatic, magumo etsinga, uye tissue iri pasi peganda. Nekuti chiedza chitsvuku paganda remunhu chekupinda kwepamusoro, hachiwanikwe mune mamwe mawavelength emafungu echiedza, uye nekudaro chinozivikanwa se "optical window" yeganda remunhu.
Mwenje mutsvuku unotorwa sei nemuviri?
Mumiviri yedu, kubatwa kwechiedza kunonyanya kukonzerwa nemapuroteni, pigments nemamwe macromolecules nemamorekuru emvura, ayo mamorekuru emvura nehemoglobin mubhendi rechiedza chitsvuku chechiedza chekubatwa kwechiedza chiri chidiki, maphotons anogona kupinzwa zvakadzika mumiviri kuti atambe mhedzisiro yekurapa inoenderana, uye chiedza chitsvuku nemuviri wemunhu ndizvo zviri pedyo nemwaranzi yemafungu emagetsi, inozivikanwawo se "chiedza chehupenyu! Inozivikanwawo se"chiedza chehupenyu".
Kutorwa kwechiedza chakasiyana-siyana kuburikidza nenyama dzeganda
Pamusoro pezvo, padanho remasero, mitochondria ndiyo inonyanya kupinza chiedza chitsvuku. Chiedza chitsvuku chinopindirana nechikamu chekunwa chemitochondria, uye maphotoni ayo anonyudzwa anopinzwa mumuviri wemunhu, zvichikonzera kuti pave nemaitiro ekugadzira ma enzymes - enzyme reaction, zvekuti mitochondrial catalase, superoxide dismutase nemamwe ma enzymes ane chekuita nekushanda kwesimba remetabolism awedzere, nokudaro zvichikurumidzisa kugadzirwa kweATP, kuwedzera simba remasero enyama, uye kukurumidzisa maitiro emetabolism uye kubviswa kwema metabolites ane chepfu mumuviri. Chinokurumidzisa metabolism yemuviri uye kubviswa kwema metabolites ane chepfu mumuviri.

ImwezveOngororo inoratidza kuti kupiswa kwechiedza chitsvuku kunogona kuchinja kuratidzwa kwemajini ane chekuita neshuga,metabolism yemafuta, uye mapuroteni, zvichiita kuti zvive nyore kuti fibroblasts ishandise mafuta acids sezvinhu zvekugadzira ATP,nokudaro zvichiita kuti mafuta ashande nekukurumidzauye panguva imwe chete,zvinogona zvakare kuita kuti kuratidzwa kwemajini ane chekuita nekushandiswa kwesimba kudzorwe, dzakadai seNADH dehydrogenase, ATP synthetase, uye mapuroteni eflavin anotapurira maerekitironi, wIzvi zvinobatsira kugadzirisa nekugadzirazve matishu akakuvara, uye zvinokurudzira matishu etsinga kuti azadzise chinangwa chekurapa. Zvinogonawo kukurudzira matishu etsinga kuti azadzise chinangwa chekurapa.
Nzira dzinogona kushandiswa kudzivirira tsinga dzeuropi dzinokonzerwa nechiedza chitsvuku
Mhedzisiro yechiedza chitsvuku mumuviri wemunhu inosimudzira mifananidzo
Zvinyorwa zvakawanda pamusoro pemashandisirwo emwaranzi yechiedza chitsvuku pamwe neongororo dzakawanda dzekiriniki zvakaratidzawo kuti chiedza chitsvuku chine simba guru parunako, kupora kwemuviri, kuwedzera simba rekudzivirira muviri,nezvimwewo, uye kuti inoita basa guru mukusimudzira kuumbwa kwecorpus luteum yeovary, kudzora kuenzana kwekubudiswa kwemahormone epabonde, kunatsiridza kuona, kuderedza uremu nemafuta, uye kuderedza manzwiro.

Ongororo itsva yakaitwa nemasayendisiti ekuBritain yakaburitswa muScientific Reports yakawana kuti kusangana nechiedza chitsvuku chakadzika kwemaminitsi matatu chete pazuva chakaderedza zvakanyanya kurasikirwa nekuona, nekuona kwavo kuchivandudzika neavhareji ye17 muzana.
Mwenje mutsvuku wezuva nezuva wakaratidzwa kuti wakanaka uye une hutano
Zvakakosha kutaura kuti kurapwa nechiedza chitsvuku kwagara kuripo. Kare muna 1890, "baba vechiedza chitsvuku" NR Fenson akashandisa kurapwa nechiedza chitsvuku kurapa varwere vane chirwere chesmallpox ne lupus, achiponesa hupenyu husingaverengeki uye achidzivirira zviso zvisingaverengeki. Mazuva ano, tsvakiridzo yekutanga uye yekiriniki yekurapa nechiedza chitsvuku yakadzama uye yakatambanudzwa, uye yave mushonga "usingatsiviwi" wezvirwere zvakawanda.

Zvichibva pane izvi, timu yeMERICAN yakatanga kabhini yekuchenesesa yechizvarwa chechitatu yeMERICAN zvichibva pakutsvagurudza kwekurapa nechiedza chitsvuku, pamwe chete netekinoroji yechiedza chakawanda chakagadzirwa neMERICAN Light Energy Research Center pamwe chete nechikwata cheGerman, icho chinotungamirwa nemaenzymes epro-activation uye mitochondria kuvandudza hurongwa hweropa uye kudzora metabolic balance, uye kuderedza kukuvara kunokonzerwa nemafree radicals, kuitira kubvisa yero kubva kuma antioxidants zvinobudirira, kurerutsa pigmentation, kuchena uye kupenya ganda; uye kugadzirisa nekudzivirira metabolism. Inogadzirisawo nekudzivirira metabolism, immune regulation uye akasiyana-siyana maitiro emasero, nokudaro ichivandudza huwandu hweimmune uye mamiriro ekunze asina kunaka.
Kuti vaone kushanda kwayo chaiko, timu yeMERCAN yakambokoka mazana emapurisa ane ruzivo kuti aite basa rekutarisa zvinyorwa zvacho kwemazuva makumi maviri nemasere. Mushure mekuongororwa kwechokwadi, mazana emapurisa ane ruzivo akarumbidza zvikuru uye akatenda ruzivo rweMERCAN's 3rd Generation Whitening Chambers maererano nekunzwa, kuchena, kunyaradza manzwiro, uye kuderedza marwadzo.
