Whakaarohia, e whakaaro ana tātou katoa he DNA anō tō ia pūtau o tō tinana, tika? Koinei te mea taketake e mōhiotia ana e tātou mō te ira. Engari, he tino onge, ka taea e te tinana o te tangata te whai pūtau me tētahi atu momo DNA ehara i a rātou ake, ā, he tino rerekē. He ahua rerekē te tangi, kāore? I roto i te rongoā, ka kiia tēnei mate whakamiharo ko te 'Chimerism'. Kaua e manukanuka, ehara i te mate. Kia kite tātou he aha te mea tūturu.
He aha te 'Kimire'?
He whakarāpopototanga noa iho, ko te kimerism te noho mai o ngā huinga pūtau e rua i roto i te tinana o te tangata kotahi, he uri nō ngā tāngata e rua he rerekē te ira. Ko te tikanga tēnei, tera pea he momo DNA tō ētahi pūtau i roto i tō tinana, engari he rerekē rawa te momo DNA o ētahi atu pūtau.
Ko tētahi o ngā huarahi matua ka puta ai tēnei ko ngā whānautanga māhanga. Whakaarohia he whaea e waha ana i ngā māhanga i roto i tōna kōpū. I ngā wiki tuatahi o te hapūtanga, tērā pea ka kore tetahi o ngā kukune e whanake, ka ngaro atu rānei mō tētahi take. Ka kiia tēnei ko te Vanishing Twin Syndrome. Ina tupu tēnei, ka mimitihia ngā pūtau o te kukune ngaro e te kukune hauora e tipu haere ana. Nō reira, ka whiwhi te pēpi i ōna ake pūtau me ngā pūtau o te teina ngaro puta noa i tōna oranga.
He rerekē ngā momo pūtau e huihui mai ana i tēnei ara. I te nuinga o te wā, ka kitea tēnei rerekētanga i roto i te toto. Ka kiia ko te 'blood chimerism'. Nā te mea he kaha ngā pūtau toto e hangaia ana i roto i te hinu wheua, ā, ka taea te haere ngāwari mā te whenua whānau. E ai ki ngā rangahau, tata ki te 8% o ngā māhanga noa ka pāngia pea e tēnei āhuatanga. I roto i ngā māhanga tokotoru, ka piki ake tēnei tūponotanga ki te 21%.
He aha ngā take o te chimerism?
E ai ki tā tātou i kōrero ai i mua ake nei, ka whānau mai ētahi tāngata me tēnei mate. Heoi anō, ka taea e te tangata te whakawhanake i te chimerism i a rātou e ora ana. E rua ngā take matua mō tēnei. Me wehewehe e tātou ēnei e whai ake nei.
| Take | Whakaahuatanga o te āhua o te tupu |
|---|---|
| Te Kimerisma Whakatupu | Koinei te 'Vanishing Twin Syndrome' i kōrerohia e tātou i mua ake nei. Ka ngaro tetahi kukune i roto i te kōpū, ā, ka mimitihia ōna pūtau e tetahi atu kukune, ka mutu, e rua ngā momo pūtau e toe ana i roto i te tinana mō te roanga o te ora. |
| Kimimeri i Whiwhi | Ka mahia tēnei hei maimoatanga hauora whakaora ora. Hei tauira, whakaarohia he whakawhitinga okana . Ina whiwhi te tangata i tētahi whatukuhu mai i tētahi atu tangata hauora, ka mahi tahi te whatukuhu hou me te DNA o te kaituku. Kātahi ka whai DNA te kaiwhiwhi me te DNA o te kaituku. Pērā anō hoki mō te whakawhitinga wheua wheua . I tēnei take, ka whakawhitingahia te wheua wheua o te kaituku hauora hei utu mō te wheua wheua mate. Kātahi ka hangaia ngā pūtau toto hou katoa mai i te DNA o te kaituku. Ka taea e tēnei te whakarerekē i te momo toto o te tangata. |
He tohu kei reira mō tēnei?
Ko te rongo pai, ko te nuinga o te hunga e pāngia ana e te chimerism kāore he tohu. He maha te hunga e noho ana i ō rātou oranga katoa me te kore e mōhio kei a rātou te mate. Nā te mea kāore he whakamātautau motuhake mōna, he tino onge te whiwhi tātaritanga.
Heoi, i ētahi wā ka arahi pea tēnei ki ngā raruraru e kore e taea te whakaaro, inā koa ki ngā whakamātautau DNA.
Whakaarohia, ka whakamātauhia e te pāpā te DNA hei whakaū i te matua o te tamaiti. Engari ko te hua ka puta ehara ia i te matua o te tamaiti. E tino mōhio ana ia ko tana tamaiti tonu. Ko te mea ka tupu i konei, ki te pāngia te pāpā e te chimerism, kāore te DNA i roto i tōna toto, i tōna huware rānei, engari i roto i ōna pūtau whakaputa uri (parāoa). Ko te DNA o te tuakana i ngaro i roto i te kōpū. Kātahi ka honoa te tamaiti ki a ia i runga i te ira, me te mea he tamaiti ia nā tētahi o ōna tuakana, arā, he iramutu, he irāmutu rānei.
Ka pā anō hoki ngā āhuatanga ōrite ki te whaea. Nō reira, i te nuinga o te wā, ka kitea te chimerism i te hua o tētahi taupatupatu matapōkere i roto i tētahi whakamātautau DNA pēnei.
Ka taea e tēnei āhuatanga te whakararu i ngā raruraru nui?
Ehara te chimerism i te mate, ehara hoki i te āhua morearea, engari ka pā mai pea ētahi raruraru ki te kore koe e mōhio.
- Ngā Take Ture: E ai ki te kōrero i mua ake nei, ko ngā hua hē o te whakamātautau pātenetanga ka arahi pea ki ngā take ture nui e pā ana ki te mana tiaki tamariki. He maha ngā aituā pēnei kua pūrongohia puta noa i te ao.
- Ngā raruraru hinengaro:Tērā pea ētahi tāngata ka pāngia e te ohorere hinengaro me ngā raruraru tuakiri ina kitea he wāhanga tinana kei a rātou anō o tētahi atu.
- Te hiranga hauora: He mea nui pea kia mōhio koe ki tēnei āhuatanga i te wā e taurite ana te kiko i mua i te whakawhitinga okana.
Engari kāore he take e manukanuka ai ngā whaea mō te 'mate māhanga ngaro'. Mēnā ka puta i ngā marama tuatahi e toru o te hapūtanga, e kore e pā kino ki te whaea, ki te pēpi hauora rānei. Tērā pea kāore te whaea e kite i tētahi tohu i tua atu i te toto iti.
Karere Tangohia ki te Kāinga
- Ko te kimerism te noho mai o ngā momo DNA e rua i roto i te rauropi kotahi. He maha ngā wā ka puta tēnei mā te mimiti o ngā pūtau mai i tētahi māhanga i roto i te kōpū, mā te whakawhitinga okana/wheua rānei.
- Ehara tēnei i te mate morearea. Ko te nuinga o te hunga whai chimerism kāore he tohu.
- Ko te raru matua ka puta ake i ngā whakamātautau DNA, inā koa i ngā mea pēnei i ngā whakamātautau ira tāne, ina koa ka rerekē ngā hua.
- Ki te pā mai he raruraru kāore i whakamāramatia ki ngā hua o te whakamātautau DNA, kōrero ki tō tākuta mō te tūponotanga o te chimerism.
