Granulation ntaub so ntswg yog tsim thaum lub sijhawm kho. Qhov no yog ib tug complex ntawm fibroblasts, vascular endothelial hlwb, thiab macrophages nyob rau hauv ib tug matrix ntawm collagen thiab fibrin. Fibroblasts thiab capillaries tshwm nyob rau hauv lub qhov txhab los ntawm hnub 3. Fibroblasts siv cov fibrin clot ua ib tug matrix thiab hloov nws nrog tshiab matrix.
Lub sijhawm twg ntawm cov theem twg yog granulation cov ntaub so ntswg tsim?
theem proliferative yog yam ntxwv los ntawm kev tsim cov ntaub so ntswg granulation, reepithelialization, thiab neovascularization. Cov theem no tuaj yeem kav ntev li ob peb lub lis piam.
hom cell pib cov ntaub so ntswg granulation?
Fibroblasts, cov hlwb tseem ceeb uas tso cov ntaub so ntswg granulation, nyob ntawm cov pa kom proliferate thiab nteg cov tshiab extracellular matrix. Hauv vascularisation, tseem hu ua angiogenesis, cov hlwb endothelial sai sai loj hlob mus rau hauv cov ntaub so ntswg los ntawm cov hlab ntsha laus.
Granulation theem yog dab tsi?
Theem granulation. Lub sijhawm thib peb ntawm kev kho qhov txhab, suav nrog kev hloov pauv ntawm cov fibrin matrix ib ntus nrog cov ntaub so ntswg granulation thaum lub qhov txhab tau raug tshem tawm, suav nrog ob peb theem: rov ua epithelialization. fibroplasia, collagen deposition.
Yuav tsum tshem cov ntaub so ntswg granulation?
Nws tau lees paub los ntawm cov xim liab liab mus rau tsaus liab, feem ntau ci ntsa iab thiab muag muag, uas tau nce mus rau qib ntawm cov tawv nqaij ib puag ncig lossis siab dua. Daim ntaub no mustraug tshem tawm kom thiaj li rov ua epithelialization tshwm sim.
