Down Syndrome ua rau kev paub qeeb thiab muaj kev pheej hmoo siab rau ntau yam teeb meem kev noj qab haus huv thiab muaj ntau yam pom tau. Raws li qhov tshwm sim ntawm Down Syndrome tseem nce ntxiv hauv Asmeskas, ib lo lus nug ntau tus muaj yog tias dev puas tuaj yeem muaj tus mob Down. Txawm hais tias qee tus dev yuav pom cov tsos mob zoo sib xws,Down syndrome tsis tuaj yeem tshwm sim thiab tsis tau kuaj pom hauv canines.
Vim li cas dev tsis tuaj yeem muaj tus mob Down, thiab puas muaj lwm yam mob uas ua rau nws? Txhawm rau kawm cov lus teb rau cov lus nug no thiab ntau ntxiv, nyeem ntxiv.
Vim li cas dev thiaj tsis muaj tus mob Down?
Txawm hais tias muaj qhov zoo sib xws ntawm cov caj ces ntawm cov dev thiab tib neeg, muaj qee qhov uas tshem tawm txoj hauv kev uas tus dev tuaj yeem muaj tus mob Down. Qhov sib txawv loj tshaj plaws yog tib neeg muaj 23 khub ntawm chromosomes thaum dev muaj 38. Tsis tas li ntawd, txij li Down syndrome cuam tshuam rau 21st tib neeg chromosome, thiab 21st chromosome hauv dev tswj ntau yam ntawm lawv txoj kev noj qab haus huv, nws tsis yooj yim rau dev kom muaj Down syndrome tib yam. txoj kev uas tib neeg ua1 Txawm tias dev muaj peev xwm muaj chromosomal txawv txav (saib hauv qab), lawv DNA txawv txaus los ntawm tib neeg uas Down syndrome yeej tsis tau qhia nyob rau hauv hom canine.
Cov dev puas tuaj yeem pom cov cim uas zoo ib yam li Down Syndrome?
Thaum Down syndrome yeej tsis tau txheeb pom nyob rau hauv canines, lawv tuaj yeem raug kev txom nyem los ntawm cov teeb meem zoo sib xws. Kev loj hlob hormone deficiency hauv dev yog ib qho piv txwv zoo meej, nrog rau pituitary dwarfism.
Hypothyroidism yog ib qho piv txwv ntawm cov kab mob hauv cov dev. Tus mob no qhia tau hais tias muaj ntau yam cim uas zoo ib yam li Down syndrome nyob rau hauv tib neeg, nrog rau cov hauv qab no;
- Slower than normal growth
- Stunted loj hlob
- Shorter ceg
- Nyob rau hauv qhov qhib ntawm tus menyuam dev qhov muag thiab pob ntseg
- Ntshai tsis muaj leeg nqaij
- Tus nplaig loj txawv txawv uas tawm ntawm tus dev lub qhov ncauj
Thaum twg koj yuav tsum mus ntsib kws kho mob yog tias koj tus dev pom cov tsos mob ntawm Autism?
Raws li peb tau pom, dev tsis tuaj yeem muaj Down syndrome raws li tau hais tseg hauv tib neeg vim yog qhov sib txawv ntawm chromosomal ntawm dev thiab tib neeg. Txawm li cas los xij, txij li cov dev tuaj yeem muaj teeb meem hauv plab thiab qhia cov cim zoo sib xws, nws yog ib qho tseem ceeb kom paub thaum twg los nrhiav cov lus qhia kws kho tsiaj. Yog tias koj pom cov cim hauv qab no hauv koj tus dev, coj koj tus menyuam mus rau koj tus kws kho tsiaj hauv zos kom kuaj xyuas tiav.
- Muaj leeg tsis zoo nrog taug kev nyuaj
- Slow growth
- ntxhais ceg luv dua li qub rau tus yug
- Qhov muag thiab pob ntseg
- Tshuaj tawv nqaij
- Irregular face structure or features for yug
- Kev loj hlob qeeb, ob lub cev thiab lub hlwb
Dab tsi ua rau Down Syndrome zoo li cov tsos mob hauv dev thiab lwm yam tsiaj?
Thaum kev tshawb fawb tsis tau taw qhia rau ib qho xwm txheej tshwj xeeb, nws tau ntseeg tias kev yug me nyuam ntau dhau, thiab tshwj xeeb hauv kev yug me nyuam, tej zaum yuav yog ib qho ntawm cov ua rau Down syndrome zoo li cov tsos mob thiab teeb meem hauv dev thiab lwm yam tsiaj. Inbreeding tau pom tias ua rau muaj qhov tshwm sim ntau dua ntawm cov kab mob caj ces cuam tshuam nrog chromosomes.
Cov xwm txheej twg tuaj yeem ua rau cov tsos mob ntawm tus dev?
Qee yam mob uas cuam tshuam rau dev tuaj yeem muaj cov tsos mob zoo sib xws rau Down syndrome. Peb feem ntau cov mob uas ua raws li cov tsos mob ntawm Down syndrome hauv dev muaj xws li hauv qab no:
1. Congenital Hypothyroidism
Congenital Hypothyroidism yog ib yam mob tsis tshua muaj uas tus dev cov thyroid caj pas tsis tsim cov tshuaj hormones tsim nyog rau kev loj hlob thiab lwm yam kev noj qab haus huv ntawm lub cev thiab lub hlwb. Qhov no tuaj yeem ua rau dwarfism thiab kev txawj ntse teeb meem hauv dev, ntawm lwm cov cim.
2. Pituitary Dwarfism
Raws li nrog congenital hypothyroidism, pituitary dwarfism tshwm sim thaum tus dev lub thyroid caj pas tsis tsim ntau cov tshuaj hormones los yog tsim lawv cov nqi qis dua li ib txwm muaj. Qhov no ua rau tus dev me dua qhov nruab nrab thiab, ntau zaus, yuav txo nws txoj sia. Qee qhov xwm txheej, koj tus kws kho tsiaj tuaj yeem muab koj tus dev nrog cov tshuaj hormones ntxiv.
3. Congenital Hydrocephalus
Qhov teeb meem no tshwm sim ua rau tus dev muaj pob txha taub hau loj heev thiab qhov muag tsis pom kev. Cov kua dej txha caj qaum accumulates nyob rau hauv thiab ib ncig ntawm lub pob txha taub hau. Qee tus dev yuav muaj cov tsos mob tsawg heev uas lawv raug cuam tshuam los ntawm tus mob no, tab sis lwm tus dev tuaj yeem cuam tshuam ntau dua, suav nrog qaug dab peg thiab qhov muag tsis pom.
Puas muaj lwm yam tsiaj txhu muaj Down Syndrome?
Down syndrome tsis tshwm sim nyob rau hauv lwm yam tsiaj tsuas yog primates. Qhov laj thawj yog yooj yim; primates muaj cov kab ke chromosomal zoo ib yam li tib neeg.
Tib neeg muaj 23 khub ntawm chromosomes, thaum primates muaj 24 khub ntawm lawv. Nws tau pom tias 22nd chromosome hauv primates yuav luag zoo tib yam rau 21st hauv tib neeg. Cov kws tshawb fawb tseem tau sau tseg tias thaum tus thawj coj muaj teeb meem nrog nws 22nd chromosome, nws pom cov cim zoo sib xws rau tib neeg nrog Down syndrome, suav nrog teeb meem ntawm qhov muag thiab pob ntseg, strabismus, thiab teeb meem loj hlob. Dhau li ntawm primates, txawm li cas los xij, cov chromosomes ntawm feem ntau ntawm cov tsiaj txhu txawv txaus los ntawm tib neeg kom txwv tsis pub muaj kev pheej hmoo ntawm Down syndrome.
Txoj Kev Xav
Vim qhov sib txawv tseem ceeb ntawm DNA thiab chromosomes ntawm tib neeg thiab dev, dev yeej tsis tau kuaj pom tus mob Down. Hloov chaw ntawm 23 khub ntawm chromosomes peb tib neeg muaj, dev muaj 38. Cov chromosome thib 21, uas ua rau muaj teeb meem rau tib neeg, muaj ntau yam sib txawv ntawm cov dev thiab cuam tshuam rau lwm qhov ntawm lawv lub cev thiab lub hlwb. Nws tuaj yeem ua tsis zoo tab sis yuav tsis ua rau tib yam mob lossis cov cim qhia. Txawm li cas los xij, dev tuaj yeem muaj lwm yam kev txawv txav hauv lub cev, thiab cov kws tshaj lij ntseeg tias feem ntau yog tshwm sim los ntawm kev yug me nyuam thiab kev yug me nyuam.
