Karyotype - ndi kusanthula umene akutionetsera chinsinsi cha chibadwa

Masiku ano, kawirikawiri zambiri zopeka kapena ofufuza mafilimu Apolisiwo kupeza zikuoneka woona wa upandu kumachititsa phunziro pa karyotype - kuwunika kuti tione DNA anthu ndi mogwirizana, ngati n'koyenera zitsanzo ulamuliro. Mosakayikira, maphunziro majini zaululidwa anadzetsa yochizira matenda ndi Kulenga kwa zipangizo zoyenera, njira za kafukufuku ndi zikamera wa mibadwo akatswiri kugwira ntchito limodzi ndi zida izi.

Studies pa karyotype - njira zofunika matenda majini

karyotype kuphunzira kuchita zachipatala yavlyayuetsya imodzi mwa magawo malangizo chibadwa. Mfundo kuphunzira zachokera kuti pa maselo a chamoyo chilichonse moyo zikuchokera DNA, onyamula mudziwe chibadwa, akhala zikutsatiridwa moyo. Aliyense wamoyo, kaya mtundu wochokera kwa makolo awo theka ya DNA, imene chikugwirizana pa nthawi ya umuna - kuchokera nthawi imeneyo akuyamba chitukuko cha latsopano chamoyo. Number DNA ndi makhalidwe awo sizisintha moyo. Kwenikweni, kotero aliyense kamodzi kokha moyo ndi kuchititsa phunziro pa karyotype lapansi.

kuwunika akhoza anachita maselo a chiwalo chilichonse cha umunthu - zikuchokera DNA amakhalabe zikutsatiridwa kaya minofu ndi njira zochepa chabe pamalangizo zakuthupi. kafukufuku zikufunika mankhwala, kumene matenda njira zamakono ntchito kuti azindikire zotheka matenda majini ngati wodwalayo komanso abale ake. Anapeza ntchito mu kusanthula sayansi azamalamulo kumene karyotype maselo ntchito mayeso zosiyanasiyana ndi mankhwala azamalamulo.

Kodi kafukufuku

Muyenera kudziwa kuti ngati n'koyenera, akhoza pansi kuphunzira aliyense wa maselo a anthu m'thupi, ndi zina ngakhale maselo akufa (tsitsi, misomaliyo, khungu). Komabe, liwiro apeza zotsatira zimadalira m'mene mofulumira maselo a makamaka thupi minofu zidzasankhidwa. Ndi yekhayo ndi mtima maselo kugawa zambiri zikhoza kuchitidwa mayeso mofulumira karyotype lapansi. Analysis ngakhale m'mikhalidwe yabwino zitenga kanthawi - mu nkhani yabwino, chifukwa okwana kuphunzira angapezeke pa manja a masiku 25-30. Zochita azamalamulo angagwiritsidwe ntchito mayesero mofulumira - imafunika nthawi zochepa, koma chifukwa awo amafuna yachinsinsi zina monga mwachizolowezi.

phunziro ikuchitika culturing wa nyemba zakuthupi anatengedwa zasayansi. Pa TV wapadera michere ndi okha chikhalidwe m'galasi selo ikuchitika. Nthawi zambiri, magazi zikutengedwa kufufuza - ndi capillary (chosowa kwambiri), kapena venous, osachepera - kuchipala ndi mucosa m'kamwa. Analysis wa karyotype magazi ambiri masiku ano madokotala nthawi zambiri ntchito uphungu ndi dokotala chibadwa. njira yodalirika chuma kumathandiza kupeza maselo zokwanira (makamaka magazi), umene wakula zasayansi, mapulani wodetsedwa ndi mosamala utoto wapadera.

Pamene kusanthula karyotype n'kofunika

Nthawi zambiri zimachitika kuti sterility banja wolakwa kusintha chromosomal maselo a makolo kudzakhala, kotero osabereka kapena kabwerebwere padera kufufuza karyotype. kuwunika nthawi zotchulidwa mu kuphatikiza kafukufuku zoimbidwa ndi zasayansi, koma ziyenera kuperekedwa kokha pa malangizo a dokotala, zotsatirazi anayendera ndi kungoyeza.

kusanthula kulembapo ndi kudziwika matenda otengera, makamaka opatsirana monga autosomal recessive khalidwe (matenda kumachitika kokha pamene "msonkhano" imene imachititsa awiri pathological). Lero, kafukufuku Akhozanso kusankha ngati mwana wakhanda ndipo munthu moyo wake, ndi mwana wosabadwayo - pa matenda olanda. Mu nkhani iyi, mfundo kusanthula ndi amniotic madzimadzi, nsengwa kapena particles chorionic.
