Kana uine pamuviri, chiremba anokukumbira kuti uite bvunzo dzakasiyana-siyana, handiti? Dzimwe nguva paunonzwa mazita ebvunzo idzi dzekurapa, unonzwa kutya uye kuda kuziva. Kune vanhu vazhinji, bvunzo isingazivikanwe zvishoma, asi yakakosha zvikuru, inonzi bvunzo yekaryotype. Vamwe vanhu vanoidaidzawo kuti bvunzo yemajini, bvunzo yechromosome, kana cytogenetic analysis. Usanetseke, mazita aya anoreva bvunzo imwe chete. Nhasi, tichataura nezvazvo zviri nyore, nenzira yaunogona kunzwisisa.
Chii chaizvo chinonzi Karyotype Test iyi?
Zvichitaurwa zviri nyore, bvunzo yekaryotype inotarisa zvakanyanya machromosome ari mukati memasero emuviri wedu. Funga nezvemachromosome aya sepurani yekuvakwa kwemuviri wedu. Bvunzo iyi inotarisa chero shanduko kana kusarongeka mupurani iyi.
Munguva yekuzvitakura kwako, chiremba wako angangoda kuongororwa kuti aone kana paine zvimwe zvirwere zvemajini ne chromosome mukati me trimester yekutanga neyechipiri. Kazhinji, mhedzisiro yebvunzo idzi inenge iri mukati menguva yakatarwa. Hapana kumwe kuongororwa kunodiwa.
Zvisinei, kana bvunzo dzekutanga idzodzo dzichiratidza kuti panogona kunge paine dambudziko, chiremba wako anogona kukukurudzira kuti uite imwe bvunzo, senge bvunzo yeKaryotype. Izvi zvinogona kusimbisa zvechokwadi kana mwana ari kukura mudumbu aine dambudziko remajini kana chromosome.
Chii chinotsvakwa nebvunzo ye karyotype?
Kazhinji, munhu ane hutano hwakanaka ane machromosomes 46. Mwana anowana 23 kubva kuna amai uye mamwe 23 kubva kuna baba.
Dzimwe nguva, mwana anogona kuva nechromosome yekuwedzera, chromosome imwe chete isipo, kana kuti panogona kunge paine shanduko isingawanzoitika mune imwe yemachromosome. Kuongororwa kwekaryotype kunogona kuona kana izvi zviri izvo. Aya ndiwo mamwe ematambudziko anonyanya kutariswa navanachiremba nebvunzo iyi.
| Mamiriro | Zvakatsanangurwa zviri nyore |
|---|---|
| Down syndrome (Down syndrome - Trisomy 21) | Mwana ane machromosome matatu (ekuwedzera) panzvimbo pemaviri ari pachromosome 21. Izvi zvinokanganisa chitarisiko chemwana uye kugona kwake kudzidza. |
| Chirwere cheEdwards (chirwere cheEdwards - Trisomy 18) | Mwana ane chromosome 18 yekuwedzera. Vana ava vanowanzova nematambudziko akawanda ehutano, uye vazhinji havararame kwenguva inopfuura gore. |
| Chirwere chePatau (Trisomy 13) | Mwana ane chromosome 13 yekuwedzera. Vana ava vanowanzova nechirwere chemwoyo uye vane dambudziko guru repfungwa. Vazhinji havararame kupfuura gore. |
| Chirwere cheKlinefelter | Mwana wechirume ane chromosome X yekuwedzera (seXXY). Kuyaruka kwavo kunogona kunonoka, uye vana vanogona kurasikirwa nekukwanisa kubereka vana. |
| Turner syndrome | Mwana wechikadzi anogona kunge asina kana kukuvara chimwe chezvikamu zvake zveX chromosome. Izvi zvinogona kukonzera chirwere chemwoyo, matambudziko emutsipa, uye hupfupi. |
Kuongororwa kwekaryotype hakungoshandiswi chete kuona zvikanganiso zvemajini mumwana panguva yekuzvitakura, asiwo kune zvimwe zvakanakira.
- Kana uchinetseka kubata pamuviri , kana kuti wakambobvisa pamuviri kakawanda, chiremba wako anogona kuita bvunzo iyi kuti aone kana paine matambudziko ari mumakromosomu ako kana emumwe wako.
- Tsvaga kana uchigona kupa mwana wako chirwere chemajini.
- Kana mwana akafa, simbisa kana chikonzero chacho chiri dambudziko remajini .
- Tsvaga chikonzero chematambudziko emuviri kana ekukura angave ari kusangana nemwana wako kana mwana mudiki.
- Kana zvisingawanzoitiki apo bonde remwana achangoberekwa risingazivikanwe, simbisa izvozvo.
- Mamwe marudzi egomararaGomarara rinogona kukonzera shanduko mumachromosomes. Kuongororwa kwekaryotype kunogona kubatsira kuona kurapwa kwakakodzera.
Ndedzipi mhando idzi dzebvunzo dzeKaryotype uye dzinoitwa riini?
Kuongororwa uku kunogona kuitwa chete pamavhiki akati wandei ekuzvitakura. Chiremba wako ndiye achasarudza kuti ndeipi bvunzo yakakunakira, zvichienderana nekuti wava nenguva yakareba sei pamuviri wako uye zvinhu zvinokuisa panjodzi.
Mwana ane mukana wekuva nedambudziko re chromosome mune zvinotevera:
- Kana une makore anopfuura makumi matatu nemashanu ekuberekwa.
- Kana uine mwana ane chirwere chechromosome , kana kuti mumwe munhu mumhuri mako ane chirwere ichi.
- Kana iwe kana mumwe wako muine zvimwe zvinhu zvisina kunaka mumachromosome avo.
- Kana wakambobvisa pamuviri kare kana kuti wakambozvara mwana akafa.
Kune mhando mbiri huru dzebvunzo dzinoitwa:
1. Kuongororwa kweChorionic Villus Sampling (CVS)
Mukuita izvi, chiremba anoshandisa tsono refu kubvisa chidimbu chidiki chenyama kubva muplacenta , iyo inopa chikafu kumwana. Masero aya anotumirwa kurabhoritari kuti aongororwe. Izvi zvinogona kubatsira kuona kana mwana ane matambudziko emajini akadai seDown syndrome, trisomy 13, kana trisomy 18.
- Nguva yekuzviita: Pakati pemavhiki gumi kusvika gumi nematatu epamuviri.
- Njodzi: Pane mukana mudiki wekubviswa pamuviri kubva pakuongororwa uku (anenge mukadzi mumwe chete pavakadzi zana vanoongororwa). Panewo mukana wekuti mwana awane mukana uyu, saka vanachiremba vanokurudzira izvi chete kana paine mukana mukuru wekuti mwana awane dambudziko.
2. Amniocentesis
Mubvunzo uyu, chiremba anopinza tsono refu mudumbu mako otora mvura shoma yeamniotic yakakomberedza mwana ari mudumbu. Masero emwana ari mumvura iyi anotumirwa kunoongororwa. Pamusoro pematambudziko ese emajini anotsvagwa neCVS test, inogonawo kuona zvirwere zvakakomba zvinokanganisa uropi hwemwana kana musana (neural tube defects).
- Nguva yekuzviita: Pakati pemavhiki gumi nemashanu kusvika makumi maviri epamuviri.
- Njodzi: Pachine mukana mudiki wekubuda pamuviri, asi wakaderera pane weCVS (anenge mukadzi mumwe chete pavakadzi mazana maviri vakaongororwa).
Pane njodzi dziripo here mumiedzo iyi?
Ehe, sezvatakambokurukura, kune dzimwe njodzi dzine chekuita nenzira dzinoshandiswa kuwana masero aya. CVS kana Amniocentesis hazviwanzo kukonzera kupfupfudzika kwepamuviri . Panewo mukana mudiki wekubuda ropa rakawanda kana hutachiona. Chiremba wako achakurukura newe zvese izvi zvakadzama. Saka usati wavhunduka, bvunza chiremba wako chero mibvunzo yaungave nayo.
Chii chinoitika mushure mekunge mhinduro dzebvunzo dzabuda?
Ichi ndicho chinhu chinonyanya kukosha. Mhedzisiro yekuongororwa kwekaryotype yakanyatsojeka . Kureva kuti, kana mhinduro dzagamuchirwa, unogona kuziva zvechokwadi kana mwana 'ane' dambudziko remajini kana kuti 'asina'.
Izvi hazvina kufanana neongororo dzakamboitwa kare. Dzaingotaura chete kana njodzi yacho yaive 'yakakwira' kana 'yakaderera'. Asi mhedzisiro yebvunzo yeKaryotype haisi fungidziro, asi chisimbiso.
Kana wangowana mhinduro, chiremba wako achakurukura newe zvakadzama uye achakutsanangurira matanho aunofanira kutora anotevera.
Mharidzo Yekuenda Nayo Kumba
- Kuongororwa kwekaryotype inzira yakakosha yekuongorora majini inoongorora kusarongeka kwemachromosomes mumasero edu.
- Kana bvunzo dzekutanga panguva yekuzvitakura dzichiratidza njodzi, bvunzo iyi inoitirwa kusimbisa kuti zvirwere zvakaita seDown syndrome zviripo here.
- Nzira dzakadai seCVS neAmniocentesis, dzinounganidza masero ekuita izvi, dzine mukana mudiki wekubuda kwepamuviri, saka dzinongoitwa chete kana zvanyanya.
- Mhedzisiro yebvunzo yekaryotype haisi fungidziro yakaita se "njodzi yakakwira/yakaderera", asi mhinduro chaiyo inoti "pane dambudziko/hapana dambudziko".
- Inzwa wakasununguka kubvunza chiremba wako kuti akutsanangurire chero chauri kufunga nezvebvunzo iyi, njodzi dzayo, uye mhedzisiro yayo.
