Munhu mukuru munhu ane mumuviri wake pakati pemarita mana neatanhatu eropa, chinhu chakakosha pakurarama chinotenderera nemuviri kuburikidza nemidziyo yeropa. Iko kushanda kweropa kwakakosha kumuviri, kutakura okisijeni kunhengo uye munyama uye kudzivirira muviri kubva kuzvirwere uye hutachiona.
Munhu wega wega ane mamorekuru akasiyana mumasero eropa rake, uye zvinobva pane izvi ndipo panoumbwa mapoka eropa mana. Aya mamorekuru anonzi antigen anopa kumuka kumapoka mana ayo ari erudzi A, B, O uye AB. Asi pamusoro pezvo, kune vanhu vazhinji vane chimwe chinhu chimwe muropa ravo, puroteni inova chikamu chemasero matsvuku eropa. Uye kubva ipapo iyo Rh factor inoberekwa, vanhu vane protein iyi vanozove Rh positive uye avo vasina, Rh negative.
Kunyangwe nanhasi hazvizivikanwe zvechokwadi kuti nei misiyano iyi iripo maererano nerudzi rweropa, asi zviripo dzidziso inoshamisira kwazvo inoenderana nekushanduka-shanduka. Kubudikidza nematanho akasiyana emunhu mukutanga, ropa raifanirwa kuchinjira kune akasiyana mararamiro, achichinja nekutambira maantigen akasiyana anoita mapoka eropa.
Kusawirirana kweropa chii?
Kuziva iro rako reropa reropa kwakakosha kwazvoKuziva zvemumwe wako zvakare, uye ungangodaro usina kumbofunga nezvazvo. Zvine musoro kuti hauna kumbobvira wafunga nezve uyu mubvunzo, sezvo paine zvakawanda zvisiri izvo pamusoro pazvo. Paunenge uchida kuwedzerwa ropa, zvinodikanwa kuti uzive iro boka rako reropa kuti muviri wako usarambe.
Vanenge 85% yevagari vepasirese vane protein inounza Rh factor, ndiko kuti, ropa ravo iRh positive. Mukupesana, vanhu vasina iyo iRh negative. Iyo Rh factor ndiyo inogadzirisa kusapindirana pakati pemapoka eropa akasiyana.
Kugamuchira ropa risingapindirane nerako kunogona kukutsamwisa matambudziko akasiyana uye matambudziko ehutano. Asi uku handiko chete kusapindirana kweropa kunogona kuitika. Mwana akazvarwa nevanhu vaviri vasina kuwirirana nekuda kweRh factor yavo anogona zvakare kusangana nematambudziko akakomba ehutano.
Kusapindirana kweropa kunokanganisa sei kubata pamuviri
Mucheche anogamuchira panguva yekubata kwake nhevedzano yezvinhu zvinogadzira nhaka yake. Ropa ndechimwe chazvo, saka mwana anogona kugara nhaka yeropa boka yemumwe mubereki. Izvo zvakare zvinoita kuti mubatanidzwa wevaviri uchaumba uye iwe uchagarawo nhaka yeRh factor.
Iyo Rh yakanaka chinhu chakanyanya zvinopesana nezvisina, saka kana amai vari Rh negative uye baba vari Rh positive, mwana anozove Rh positive akagara nhaka kubva kuna baba vake. Uye apa ndipo panogona kuve nekusawirirana pakati peropa raamai neromwana.
Iyo immune system yaamai inoziva chinhu chekunze icho chiri checheche Rh zvakanaka, zvazvinoita chimiro masoja ekudzivirira kurwisa protein iyoyo haina kuziva, nenzira imwechete iyo yaizotarisana nehutachiona kana bhakitiriya. Panguva yekuzvitakura, masoja ekudzivirira chirwere aya anogona kuyambuka placenta kuti arwise masero matsvuku eropa ane iyo 'yekunze' protein.
Migumisiro yemucheche inoshungurudza:
- Hemophilia: chirwere chekuzvarwa nacho chinokanganisa kugwamba kweropa.
- Hemolytic chirwere chevacheche (HDN)): chirwere chakakomba chinokanganisa kukura kwemwana.
- Anemia, pakati pezvimwe zvinetso zvakakomba zvehutano.
Rh inopindirana inokanganisa rini?
Muviri waamai hauna masoja ekudzivirira chirwere, kusvika pauri inosangana neropa iyo ine Rh protein. Saka kazhinji dambudziko iri haribate panguva yekuzvitakura kwekutanga, zvisinei pane mukana wekubata kuburikidza nezvimwe zviitiko zvakaita se:
- Kubvisa nhumbu zvakaitika kare
- Kuburikidza a kuwedzerwa ropa zveropa
- Kuburikidza nemaitiro ekuongororwa kwepamuviri anonzi amniocentesis
Munguva yekusununguka ndipo panenge paine mukana mukuru kuti ropa raamai nerecheche rinosangana. Nenzira iyi, muviri waamai unogadzira ma antibodies akamirira kurwiswa mune ramangwana.
Nhasi kune marapirwo akasiyana ekugadzirisa dambudziko iri, zvisinei, kuziva iro reropa boka revabereki vaviri iri nyore maitiro. Kuiziva pachine nguva kunogona kudzivirira ramangwana hutano uye kubata pamuviri matambudziko mune ramangwana mwana.
