Analysis pamusoro karyotype kwevarume - mukana kuva vabereki

Zvichida chiitiko kufara nomumwe vaviri ndiko kuberekwa kwomwana. Asi, zvinosuruvarisa iye, vakawanda vakasangana pamwe kusakwanisika yokubereka. The chikuru chinokonzera mwana mumwe vaviri nokuda zvichibvira nemagene zvirwere. Izvi imhaka kuchinja marongerwo DNA mamorekuru, umo nhamba okutodza akashatirwa kana vachibatwa mamiriro ezvakatipoteredza yaivhuvhuta apo vamwe nemagene kunotouraya kuitika. Kuti tizive zvose zvarakasiya izvi uye kudzivisa matambudziko mune ramangwana kuchikosha, kwete chete kuedza peya nemagene kugarisana, asi nokufamba samolecular magene yokuedzwa.

Kukosha Pakusarudza kuwanana karyotype

Chimwe chezvinhu zvinokosha nemagene tsvakurudzo pakugadzirira pakunambwa ndiko kuongorora pamusoro karyotype ari kuwanana. Karyotype - tsanangudzo okutodza zvose unhu kuti DNA vatakuri. Ongororo iyi kunoita tinosarudza majini chirwere kana kuti kufanotaura mukana panowanikwa yavo mwana. Panoongororwa mumwe mubereki vanoshorwa yakatarwa okutodza pane mukana kuti mwana anogona kuzvarwa zvakakomba muchimiro mupfungwa retardation kana zvimwe zvirwere. Human karyotype haigoni kuchinjwa, asi nenguva kutsunga Kutsauka nzira inoshandiswa kuona karyotype ari mudumbu uye zvingangoita kurapwa.

Panewo yakakwirira ndingangokuvara kukundikana pamuviri chete chromosomal abnormalities. Asi nemhaka nenguva tsanangudzo dambudziko uye yepakutanga kuronga pamuviri pane mukana wokuva mwana ane utano. Muzviitiko pasina mukana kurapwa mumwe mudzimai, akasika rinokosha anyatsoronga chirongwa kubatsira vakaroorana muna mwana pakuzvarwa.

Pashure karyotype murume kwatemwa, vaite Diagnostics pakati chromosomal syndromes - karyotype. Zvakabuda nechirwere ichi vanogona kuona fetus abnormalities yakafanira kune STRUCTURAL zvachinja chromosome wakaiswa mubereki. In kupfuura dzakabudirira, dzakadai kuongorora zviri fanira pamberi muchato. Zvikurukuru zvinokosha kuti tiite ongororo iyi mumhuri kuti kare haagoni pamuviri, kana mune zviitiko apo paiva kupfupfudzika (kubva pamuviri). Kuziva karyotype hwevakadzi iyi - rinokosha basa. Ndokusaka mufambiro nemiedzo yakadaro inodiwa uye kudzivisa kuberekwa vana nechirwere chakakomba.

Analysis nokuti karyotype

Process nokuti Pakusarudza karyotype pakati kuwanana iri zvachose nyarara uye ari kupfuura ropa kubva tsinga. Results takatsunga mukati masvondo maviri, uye anogona kuona zvarakasiya mu chromosome marongerwo uye nhamba. Nemigumisiro yakanaka uwandu okutodza mune utano munhu akaenzana 46, vaviri zviri kurondedzerwa se pabonde uye xy mune varume uye XX vanhukadzi. In kakawanda kacho, mashoko okutodza kana naGene kunotouraya anokonzerwa Kumwe kuchinja kunotanga, zvichiita kuti hazvibviri akatakura mwana uye, sezvo zvakaguma abva pamuviri kana kushaya mbereko.

Ropa akatorwa kuona vawanani karyotype firimu mononuclear leukocytes, vakabatana tichishingaira masero vanokwanisa kuparadzanise. Pane imwe nguva, boka muitiro anomiswa, uye zvichiguma masero vakanga akasvibiswa maikorosikopu uye mifananidzo kuwedzera. Staining rinoitwa pachishandiswa siyana madhayi (chekare uye spectral miedzo) kuti anogovera kutarisana cherudo kwakakwana yakatarwa okutodza.

Nokuti yakanakisisa kunoguma nechirwere uye kurapwa asakwanisa kuita vana uye nezvimwe zvirwere yakanakisisa mhinduro ndiko kutaura Center for Reproductive Medicine. In nzvimbo izvi, vaviri vanogona navo zano zvakakodzera ruzivo nyanzvi, vakazochinja kubatsira kuwana zvakanaka mishonga. Mari yokuedzwa uye kurapwa mune nzvimbo idzi anoenderana pfungwa dzavo uye kurerukirwa uye kwakakodzera kuita chinangwa ichi - kuberekwa vana utano.
