A Tarisa Tsvakurudzo Pamusoro Pemvere-Dye Dambudziko
Kana bvudzi rako richive jena, iwe unogona kuva imwe yeiyo inofungidzirwa chetatu yevakadzi vakuru-uye chegumi chevarume vakuru-vanosarudza kuifukidza nemakemikari. Mishonga iyi inobva pane imwe nguva yezvitsvaidzo zvinoshandiswa zvinoisa muto wakajeka kumashure mutsvuku, yose inoenda kuisa mavara midzi kuti ibvise grey vhiki nhatu dzose.
Ndezvipi zvakachengeteka izvo zvishandiso zvemavara?
Imwe tsvakurudzo yedzinza yakaratidza huwandu hwakawanda hwevamwe kanzira pakati pevashandi vevashandi nevadziri vemvura vanoshandisa aya mazvigadziro panzvimbo yavo yebasa, uye pakati pevanhu vanoshandisa pamba. Zvimwe zvidzidzo zvakaratidza kwete kubatana.
Ita Dhisi Dzemusoro Chikonzero Kanzira Here?
Mhando dzeBvudzi Mutsvuku : Kune zvakasiyana-siyana zvezviwanikwa zvinowanikwa kuti zvive nemakore ekukwegura kwebvudzi . Zviratidzo zvenguva pfupi zvinoshambidzwa nyore nyore nokuti hazvisanganisiki nechokunze, kana cuticle, yebvudzi rebvudzi. Miti-miviri-yakagadzikana inopinda uye inotapira cuticle, inosvika kumasvipo matanhatu kusvika kune gumi. Dhayi dzenguva dzose dzinonyanya kuzivikanwa, dzinoita anenge 80% yemusika. Vanopedzisa kureba kwenguva refu kuburikidza nekusika mamolekemu mavara mukati memubvu webvudzi pachawo.
Kudzivirirwa Kunetseka : Pakazosvika pakati pa1970 imwe tsvakurudzo yakagumisa kuti zvikamu zvebvudzi rinogara rakagadzirwa, kusanganisira mamwe mafuta anonhuhwirira, zvakakonzera kenza mumhuka. Somugumisiro, vazhinji vanogadzira zvakabvisa izvo zvigadzirwa muna 1980, saka US States Food and Drug Administration (FDA) uye mutsara weNational Cancer Institute mutsvaga wekutsvaga hutano pamusoro pemvere dzemvere dzinowanzoreva ngozi dzinoshandiswa nekushandiswa mushure mokunge, kana shure, gore iroro.
Zvinosuruvarisa, pane zvidzidzo zvishomanana kubva ipapo izvo zvakanyatsosimbisa dambudziko-kana kusava nemukana - wekenza inobatanidza nevhudzi dhayi. Mukuwedzera, tsvakurudzo inenge iripo haisi nguva dzose kusiyanisa pakati pemhando yeaye (yenguva pfupi, yakasara-inogara, yakagadziriswa) inoshandiswa nenyaya dzayo kana kuti nguva yakawanda yekushandiswa.
Munhu anoyemura midzi masvondo mashomanana ane mazamu akakura akawanda kune munhu anoshandisa kwenguva shoma mwedzi mishoma. Nzvimbo huru dzekutsvakurudza dzinosanganisira kenza yemukaka , marrow uye ropa rekenza seasina Hodgkin lymphoma uye leukemia , uye kenza yemazamu .
Dzimwe tsvakurudzo dzakaona kubatana pakati peyesheni yakagadzikana nekenza yemukaka, kunyanya pakati penguva refu (makore anopfuura 15) vashandi vemusha. Kusiyana neizvi, chidzidzo chikuru muna 2003 chiSweden chevashandi vanodarika makumi mashanu nevashanu vevashandi vemavhisi havana kuwana kuwedzera kwekenza yekramha.
Imwe tsvakurudzo pamusoro peii neropa uye mararamiro emaronda epafupa, seasina Hodgkin lymphoma uye leukemia, yakaratidzawo mhinduro dzinopesana. Mutsva wekuongorora 2007 wezvikamu zvina zvekutsvakurudza, zvinosanganisira boka rose revakadzi vanopfuura 10 000, vakaona kuti kuwedzera mune rimwe rudzi rwevanhu vasiri Hodgkin lymphoma vakawanika chete kuvakadzi vakatanga kushandisa vhudzi remvere pamberi pe1980, kunze kwekuwedzera kwe follicular lymphoma pakati pevashandi vechikadzi vemucheka wakavaraidza, uyo akatanga kuisa mavara shure kwe1980. Misi yakajeka inowedzera mamwe amine anonhuhwirira, ayo anoumba "asina kumira" asina ruvara rwechivara.
Kwete kuwirirana pakati pebvudzi dhayi uye kenza yemazamu kwawanikwa.
Kukanganisa kwekuzvarwa : Mumwe mubvunzo unowanikwa kuvakadzi vazhinji pamusoro pengozi yekuremererwa kwekuberekwa, kana kuburikidza nekushandiswa kwega kana kuti kuonekwa munzvimbo yebasa.
Zvimwe zvidzidzo zvemhuka zvakaratidza teteti - kana kukanganisa kuberekwa-zvichikonzera - zvinokonzerwa nepamusoro. Hapana zviremera zvinoberekwa zvakabatanidzwa mukushandiswa kwevanhu, zvisinei, zvichida nokuti kunyanya kwemakemikari kuburikidza neganda zvakanyanya.
Kunyange zvakadaro, kutadza kune rumwe rutivi rwekuyeuchidza, vanachiremba paChirongwa cheamaiki muToronto's Hospital yeVarwere Vana vanokurudzira kuti vakadzi vanopedza kuveura vhudzi ravo kusvika katatu kana kana panguva yekuzvitakura. Kune vabati vehove, pavanenge vane pamuviri, amaiisk vanokurudzira kuvhara magirafu nekushanda munzvimbo yakanaka yevhenekeri kwete kwemaawa makumi matatu nemaviri pavhiki.
Zvichipa zvimwe zvinopesana zvinotsvakurudza zvitsvuku zvebvudzi uye kenza kazhinji, FDA inotaura zvinotevera mirayiridzo yekushandisa yakachengeteka:
- Siyai vhudzi rebvudzi pane imwe nguva yakakurudzirwa.
- Kupfeka magasi kana kuveura bvudzi.
- Sungai chikafu chechizoro zvakanaka nemvura mushure mekugadzira.
- Usambozonganisa mimwe yemhando yemicheka michina.
- Dzivisa mamwe matambudziko, akadai sekutumira dermatitis kana kuti vhudzi remvere dzemvere , nekutevera zvose zvinyorwa zvinyorwa uye nyevero.
