A: Cellular atrophy yog ib hom kev hloov kho uas cov hlwb txo qhov loj thiab ua haujlwm vim qhov txo qis hauv kev txhawb nqa lossis kev xav tau.
Q: Cellular metaplasia yog dab tsi?
A: Cellular metaplasia yog thaum cov neeg laus cov hlwb hloov mus rau hauv ib hom cell sib txawv vim muaj kev mob ntev los yog tsis tu ncua. Qhov no tej zaum yuav yog ib qho kev tiv thaiv teb los yog hloov mus rau ib puag ncig.
Q: Thiab thaum kawg, cellular dysplasia yog dab tsi?
A: Cellular dysplasia yog tus cwj pwm los ntawm kev loj hlob ntawm tes tsis zoo, nrog rau kev hloov pauv ntawm cov qauv thiab kev ua haujlwm. Nws yog lub xeev precancerous thiab cuam tshuam nrog kev pheej hmoo ntawm kev tsim mob qog noj ntshav.
Nco ntsoov tias tsab xov xwm no tsuas yog muab cov ntsiab lus dav dav ntawm ntau hom kev hloov pauv ntawm tes rau cov ncauj lus kom ntxaws ntxiv, sab laj cov chaw tshwj xeeb thiab cov kev tshawb fawb tshawb fawb.
Cov lus kawg
Hauv kev xaus, los ntawm tsab xov xwm no peb tau tshawb xyuas kom meej txog ntau hom kev hloov pauv ntawm tes thiab nws qhov tseem ceeb hauv kev ua haujlwm thiab cov lus teb ntawm cov kab mob mus rau sab nraud lossis sab hauv stimuli. Los ntawm hypertrophy thiab hyperplasia mus rau atrophy thiab metaplasia, txhua yam ntawm cov cellular adaptation mechanisms muaj cov lus teb tshwj xeeb los xyuas kom cov nqaij muaj sia nyob thiab homeostasis.
Tsis tas li ntawd, peb tau hais txog qhov tseem ceeb ntawm kev nkag siab thiab paub txog cov kev sib txawv ntawm cov cellular adaptation, vim lawv tuaj yeem yog cov cim ntawm cov kab mob, kev hloov pauv pathological lossis txawm tias cov cuab yeej kho mob rau kev kuaj mob thiab kev kho mob. Cov kev tshawb fawb thiab kev soj ntsuam ntawm cov kev hloov pauv ntawm cov cellular no tso cai rau peb kom nkag siab zoo txog cov txheej txheem ntawm tus kab mob, nrog rau kev txheeb xyuas cov tswv yim kho mob los daws lawv.
Hauv cov ntsiab lus, cellular adaptation yog ib qho nyuaj thiab qhov tshwm sim uas tso cai rau cov hlwb hloov kho thiab muaj sia nyob hauv qhov chaw hloov pauv. Los ntawm kev nkag siab thiab kev kawm txuas ntxiv ntawm ntau yam kev hloov pauv ntawm tes, peb tuaj yeem ua tiav kev kho mob thiab biology, txhim kho peb lub peev xwm los kuaj xyuas thiab kho cov kab mob zoo dua thiab txhawb kev noj qab haus huv ntawm tib neeg.
Raws li ib txwm muaj, kev paub txog kev tshawb fawb thiab kev tshawb fawb txuas ntxiv mus, cia peb nthuav peb txoj kev nkag siab ntawm cov txheej txheem cellular thiab lawv cov kev hloov pauv. Peb cia siab tias tsab xov xwm no tau muaj txiaj ntsig zoo rau kev nkag siab txog ntau hom kev hloov pauv ntawm tes thiab lawv qhov tseem ceeb hauv tshuaj thiab biology.
