Collagen fiber yog cov protein loj zais los ntawm fibroblast, muaj li ntawm extracellular matrix los hloov mob lub cev muaj zog thiab ua haujlwm. Collagen kev tshem tawm cov fibers yog qhov tseem ceeb ntawm 8-10 hnub tom qab raug mob.
Tom qab ntawd, ib tus tseem tuaj yeem nug, lub luag haujlwm ntawm cov txheej txheem sab nrauv yog dab tsi?
Cov extracellular matrix pab cov cell kom sib koom ua ke thiab tswj hwm tus xov tooj ntawm tes kev ua haujlwm , xws li adhesion, migration, proliferation, thiab differentiation. Nws yog tsim los ntawm macromolecules, hauv zos zais los ntawm cov neeg nyob hauv hlwb.
Tsis tas li, yuav ua li cas cov qauv ntawm cov txheej txheem sab nrauv hloov pauv tom qab qhov txhab rau cov ntaub so ntswg tshwm sim? ECM muaj pes tsawg leeg hauv daim tawv nqaij uas muaj kev ruaj khov rau cov neeg laus noj qab haus huv cov ntaub so ntswg hloov tom qab qhov txhab kho. Qhov no cuam tshuam nrog cov txheej txheem txhim kho qeeb uas yog xoob thiab muaj dej ntau ECM uas tso cai rau cov cell nkag mus thiab kho tau maj mam hloov los ntawm denser ECM tsim los ntawm collagen.
Ib tus kuj tseem yuav nug tau, tsev neeg enzyme twg yog lub luag haujlwm loj rau kev ua kom cov protein tsis zoo hauv kev kho qhov txhab?
Cov pab pawg loj ntawm enzymes lub luag haujlwm rau collagen thiab lwm yam protein degradation nyob rau hauv extracellular matrix (ECM) yog matrix metalloproteinases (MMPs).
Dab tsi cuam tshuam rau kev kho qhov txhab?
Cov yam tham txog suav nrog oxygenation, kis kab mob, hnub nyoog thiab poj niam txiv neej pw, kev ntxhov siab, ntshav qab zib, rog, tshuaj, cawv, haus luam yeeb, thiab khoom noj khoom haus. Kev nkag siab zoo ntawm qhov cuam tshuam ntawm cov no yam ntawm kev kho yuav ua rau muaj kev kho kom zoo dua qub kho qhov txhab thiab daws teeb meem qhov txhab.

Cov protein twg hauv qab no ua lub luag haujlwm tseem ceeb hauv kev khi cov tshuaj protein protein?
Albumin thiab al acid glycoprotein yog qhov tseem ceeb tshaj plaws thauj cov protein hauv cov ntshav. Albumin muaj cov chaw tshwj xeeb rau cov kua qaub thiab cov tshuaj yooj yim sib txuas thiab tuaj yeem cuam tshuam nrog lawv hauv cov ntshav vim tias qhov chaw thib peb raug daig tsuas yog digoxin
Dab tsi yog lub luag haujlwm ntawm kev faib cell hauv kev kho qhov txhab?
Socatic cell faib ua cov cell tshiab, tso cai rau lub cev loj hlob, thiab tseem hloov cov hlwb puas, cia lub cev kho nws tus kheej. Thaum lub sij hawm me nyuam mos somatic cell division tshwm sim sai dua, tab sis thaum koj loj hlob, 'mitosis' qeeb. Piav lub luag hauj lwm ntawm cell division nyob rau hauv yuav kho
Lub koom haum tseem fwv twg muaj lub luag haujlwm tseem ceeb rau pej xeem kev noj qab haus huv?
FEDERAL PUBLIC HEALTH AGENCIES Cov koom haum tseem ceeb suav nrog Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Hauv Tebchaws (NIH), Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Pabcuam Kev Noj Qab Haus Huv (HRSA), CDC, Kev Ua Phem Txhaum Cai thiab Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv (SAMHSA), thiab Lub Chaw Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Zoo (AHRQ. ), thiab lawv cov ua ntej
Qhov xwm txheej twg suav nrog kev nkag siab zoo uas tsis muaj lub hauv paus hauv kev txhawb nqa sab nraud?
