Qhov sib txawv ntawm qhov caws pliav thiab cov ntaub so ntswg ib txwm yog nyob rau hauv daim tawv nqaij caws pliav, collagen fibers yog taw qhia nyob rau hauv ib qho kev taw qhia, sib npaug rau ib leeg, thaum nyob rau hauv cov ntaub so ntswg ntawm daim tawv nqaij, collagen fibers yog oriented random rau ib leeg.
daim tawv nqaij yog thawj kab ntawm kev tiv thaiv ib puag ncig, microbes, thiab lwm yam txawv teb chaws. Nws yog ib qho immunologically active sensory thiab excretory ntaub so ntswg. Nws feem ntau pab tswj lub cev kub thiab tso cai rau cov kev xav xws li kov, kub thiab txias. Ntxiv mus, daim tawv nqaij yog lub cev loj tshaj plaws ntawm lub cev, nrog rau thaj tsam ntawm 20 square feet. Vim raug mob, kub hnyiab, phais, thiab pob txuv, daim tawv nqaij ib txwm hloov mus rau cov caws pliav. Yog li ntawd, daim tawv nqaij caws pliav thiab daim tawv nqaij ib txwm yog ob hom ntawm daim tawv nqaij.
Dab tsi yog Scar Tissue?
Cov ntaub so ntswg yog tsim los ntawm collagen fibers uas yog taw qhia hauv ib qho kev taw qhia, sib npaug rau ib leeg. Nws yog ib pawg ntawm cov hlwb thiab collagen fibers uas npog qhov chaw raug mob. Nws tuaj yeem txhim kho ntawm daim tawv nqaij vim muaj ntau yam xws li kev raug mob, kub hnyiab, phais, thiab pob txuv. Lwm qhov chaw ntawm lub cev kuj tuaj yeem tsim cov caws pliav, xws li hauv cov leeg nqaij, tsis ntev tom qab lub plawv nres. Cov ntaub so ntswg tuaj yeem tshwm sim hauv peb txoj kev: keloid, hypertrophic, thiab contracture.
Daim duab 01: Scar Tissue
Keloid yog ib qho tawv nqaij tawv tawv tawv tawv nqaij tawv nqaij. Ib qho caws pliav hypertrophic yog ib hom caws pliav uas ploj zuj zus mus rau lub sijhawm txawm tias nws zoo li cov ntaub so ntswg keloid. Daim ntawv cog lus caws pliav feem ntau tshwm sim tom qab hlawv raug mob. Cov caws pliav no tuaj yeem cuam tshuam qhov txav ntawm thaj chaw cuam tshuam. Cov kev kho mob rau cov caws pliav muaj xws li tshuaj pleev xim (corticosteroids), txhaj tshuaj (interferon), cryotherapy, radiotherapy, laser therapy, thiab mechanical therapy (pressure therapy).
Daim tawv nqaij li cas yog dab tsi?
Cov ntaub so ntswg ntawm daim tawv nqaij yog tsim los ntawm collagen fibers uas yog taw qhia random rau ib leeg. Cov tawv nqaij li qub yog tsim los ntawm peb txheej tseem ceeb: epidermis, qhov tob dermis, thiab hypodermis. Lub epidermis muaj ob peb lwm txheej. Cov txheej saum toj kawg nkaus muaj cov cell tuag. Cov hlwb tuag no raug tshem tawm ib ntus thiab raug hloov los ntawm cov hlwb ntawm txheej basal. Dermis txuas cov epidermis mus rau hypodermis, uas yog qhov tob tshaj plaws ntawm daim tawv nqaij. Lub dermis muab lub zog thiab elasticity vim nws muaj collagen thiab elastin fibers. Lub hypodermis rov yog cov ntaub so ntswg sib txuas, thiab nws kuj tseem muaj cov ntaub so ntswg adipose rau cov rog cia thiab tiv thaiv.
Daim duab 02: Daim tawv nqaij ib txwm
Nyob rau hauv tib neeg, daim tawv nqaij pigmentation txawv ntawm ntau haiv neeg. Tsis tas li ntawd, cov neeg sib txawv muaj ntau hom tawv nqaij; qhuav, ib txwm, thiab oily. Cov tawv nqaij sib txawv no muab qhov chaw nplua nuj thiab ntau haiv neeg rau cov kab mob. Nws kwv yees kwv yees li ntawm 1000 hom kab mob los ntawm 19 phyla muaj nyob ntawm tib neeg daim tawv nqaij.
Dab tsi yog qhov zoo sib xws ntawm daim tawv nqaij thiab daim tawv nqaij ib txwm?
- daim tawv nqaij thiab daim tawv nqaij ib txwm yog ob hom tawv nqaij.
- Ob hom muaj collagen fibers thiab fibroblast cells.
- Cov hom no npog cov leeg hauv qab, pob txha, ligaments, thiab cov kabmob sab hauv.
- Lawv muaj peb txheej tseem ceeb: epidermis, dermis, thiab hypodermis.
Dab tsi yog qhov txawv ntawm daim tawv nqaij thiab daim tawv nqaij ib txwm?
Cov ntaub so ntswg yog ib hom ntawm cov ntaub so ntswg tsim los ntawm collagen fibers uas tau taw qhia nyob rau hauv ib qho kev taw qhia, sib npaug rau ib leeg, thaum cov ntaub so ntswg ib txwm yog ib hom ntaub so ntswg tsim los ntawm collagen fibers uas yog taw qhia random rau ib leeg. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov caws pliav thiab cov ntaub so ntswg ib txwm muaj. Tsis tas li ntawd, cov ntaub so ntswg caws pliav undergoes structural thiab functional deterioration. Ntawm qhov tod tes, daim tawv nqaij ib txwm muaj cov qauv tsim thiab kev ua haujlwm ntawm daim tawv nqaij.
Cov hauv qab no infographic teev qhov sib txawv ntawm cov caws pliav thiab cov ntaub so ntswg ntawm daim tawv nqaij nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Scar Tissue vs Normal Skin Tissue
Daim tawv nqaij yog lub cev loj tshaj plaws uas npog tag nrho lub cev. Cov ntaub so ntswg thiab cov ntaub so ntswg ib txwm yog ob hom ntawm daim tawv nqaij. Cov ntaub so ntswg yog tsim los ntawm collagen fibers uas yog taw qhia nyob rau hauv ib qho kev taw qhia, thaum lub cev nqaij daim tawv yog tsim los ntawm collagen fibers uas yog oriented random rau ib leeg. Yog li, qhov no qhia txog qhov sib txawv ntawm daim tawv nqaij caws pliav thiab daim tawv nqaij ib txwm.
