Nws yog ib qho tshaj ntawm granulation ntaub so ntswg uas nce siab dua saum npoo av hauv lub qhov txhab thiab yog li ntawd cuam tshuam kev kho. Qhov no yog qhov lus teb tsis zoo nrog kev loj hlob ntawm fibroblasts thiab cov hlab ntsha endothelial nrog cov qauv zoo ib yam granulation ntaub so ntswg . Nws muaj spongy, friable , sib sib zog nqus liab tsos nqaij daim tawv.
Ntawm no, cov ntaub so ntswg granulation yog dab tsi?
Cov ntaub so ntswg yog kev sib txuas tshiab cov ntaub so ntswg thiab cov hlab ntsha microscopic uas tsim rau ntawm qhov chaw ntawm qhov txhab thaum lub sijhawm kho. Cov ntaub so ntswg feem ntau loj hlob los ntawm lub hauv paus ntawm lub qhov txhab thiab muaj peev xwm sau cov qhov txhab ntawm yuav luag txhua qhov loj.
Qhov thib ob, puas yog cov ntaub so ntswg tsis zoo? Mob txaj. Noj qab nyob zoo granulation ntaub so ntswg yog paj yeeb nyob rau hauv cov xim thiab yog ib qho qhia txog kev kho mob. Tsis zoo granulation yog xim liab tsaus, feem ntau los ntshav ntawm kev sib cuag, thiab tej zaum yuav qhia tau tias muaj kab mob hauv qhov txhab. Tshaj granulation los yog overgranulation kuj yuav cuam tshuam nrog kev kis kab mob los yog qhov txhab tsis zoo.
Ib qho ntxiv, koj yuav kho cov ntaub so ntswg li cas?
Kev kho cov ntaub so ntswg hypergranulation
- Siv cov dej ntsev hypertonic soaks txog plaub zaug hauv ib hnub.
- Siv cov tshuaj hydrocortisone ib lub lim tiam los pab kho cov tawv nqaij o.
- Siv cov tshuaj tua kab mob ua tshuaj tua kab mob rau ntawm stoma.
- Siv nyiaj nitrate los hlawv cov ntaub so ntswg ntxiv thiab txhawb kev kho mob.
Lub qhov txhab granulating zoo li cas?
Granulation cov nqaij yog ci liab thiab ua rau pom zoo thaum nws noj qab nyob zoo; thaum muaj ntshav tsis txaus, granulation cov ntaub so ntswg yuav daj ntseg. Cov txheej txheem ntawm granulation muab cov scaffolding thaum ntxov tsim nyog los txhawb kev kho los ntawm cov npoo ntawm lub mob.

Dab tsi yog qhov sib txawv ntawm cov ntaub so ntswg sib txuas tsis tu ncua thiab cov ntaub so ntswg sib txuas tsis sib xws?
Cov ntaub so ntswg sib txuas tsis sib thooj muaj cov fibers uas tsis tau sib dhos ua ke zoo ib yam li cov ntaub so ntswg sib txuas ib ntus. Cov ntaub so ntswg sib txuas tsis sib thooj muaj feem ntau ntawm cov fibers collagen. Nws muaj cov khoom hauv av tsawg dua li cov ntaub so ntswg sib txuas
Hom ntaub so ntswg sib txuas twg yog cov ntaub so ntswg?
Cov ntaub so ntswg reticular yog ib hom tshwj xeeb ntawm cov ntaub so ntswg sib txuas uas muaj nyob hauv ntau qhov chaw uas muaj cov ntsiab lus ntawm tes. Nws muaj ib tug ceg thiab mesh-zoo li tus qauv, feem ntau hu ua reticulum, vim yog kev npaj ntawm reticular fibers (reticulin). Cov fibers no yeej yog hom III collagen fibrils
Dab tsi yog cov khoom ntawm granulation ntaub so ntswg?
Cov xov tooj ntawm tes thiab cov hlab ntsha loj zuj zus yog ob qho tseem ceeb ntawm cov ntaub so ntswg. Cov hlwb tseem ceeb tshaj plaws yog fibroblasts thiab inflammatory cells - macrophages, lymphocytes, plasma cells, thiab neutrophils nyob ntawm theem thiab kev loj hlob ntawm cov ntaub so ntswg granulation thiab muaj kab mob
Cov ntaub so ntswg yog dab tsi thiab muaj pes tsawg hom ntaub so ntswg?
Cov ntaub so ntswg yog ib pawg ntawm cov cell uas muaj cov duab zoo sib xws thiab ua haujlwm. Cov ntaub so ntswg sib txawv tuaj yeem pom hauv cov kabmob sib txawv. Hauv tib neeg, muaj plaub yam tseem ceeb ntawm cov ntaub so ntswg: epithelial, txuas, leeg, thiab leeg nqaij. Tej zaum yuav muaj ntau cov ntaub so ntswg hauv txhua qhov ntawm cov ntaub so ntswg
Cov ntaub so ntswg inflammatory granulation yog dab tsi?
Granulation cov ntaub so ntswg yog vascularized cov ntaub so ntswg uas tsim raws li kev mob hnyav zuj zus. Cov capillaries tshiab ua rau cov ntaub so ntswg tshwm liab thiab granular, yog li lub npe. Keeb kwm, ib tus tuaj yeem pom macrophages thiab nthuav dav fibroblasts hauv cov ntaub so ntswg
