疤痕體質是這么形成的?

疤痕體質是指傷口(kou)受傷后的人(ren)的皮(pi)膚(fu),傷口(kou)會愈(yu)合,但疤痕會殘留,有(you)些會繼續向(xiang)外生(sheng)長(chang),膨脹,經過一段時(shi)間后,疤痕會在(zai)失去活力后變(bian)硬(ying)、變(bian)色,疤痕在(zai)生(sheng)長(chang)一段時(shi)間后,生(sheng)長(chang)停(ting)止,凸起部分殘留。


疤(ba)(ba)(ba)痕(hen)(hen)的身體容易(yi)留(liu)下疤(ba)(ba)(ba)痕(hen)(hen),并且不能去除。一般根(gen)據不同(tong)(tong)的形狀、不同(tong)(tong)的原(yuan)因等(deng)有不同(tong)(tong)的類型(xing)。常見(jian)的有:正常皮膚(fu)疤(ba)(ba)(ba)痕(hen)(hen)、增(zeng)生(sheng)性疤(ba)(ba)(ba)痕(hen)(hen)、凹(ao)陷性疤(ba)(ba)(ba)痕(hen)(hen)、萎縮(suo)性疤(ba)(ba)(ba)痕(hen)(hen)、凸(tu)起(qi)性疤(ba)(ba)(ba)痕(hen)(hen)、疤(ba)(ba)(ba)痕(hen)(hen)疙瘩等(deng)等(deng)。


疤(ba)(ba)痕(hen)通常是自發(fa)形成的。這是一個先天(tian)性的體(ti)質問題。疤(ba)(ba)痕(hen)經(jing)常發(fa)生在額(e)部(bu)胸部(bu)、肩部(bu)和其(qi)他部(bu)位。另外(wai),有(you)(you)疤(ba)(ba)痕(hen)的人一旦出現傷口(kou)就會有(you)(you)明(ming)顯(xian)的疤(ba)(ba)痕(hen),所(suo)以身體(ti)的任何位置(zhi)都(dou)可能出現疤(ba)(ba)痕(hen)。


目前(qian)尚不(bu)完全了解瘢(ban)痕形成(cheng)(cheng)(cheng)(cheng)(cheng)的(de)機制。人(ren)們普遍認為,瘢(ban)痕的(de)形成(cheng)(cheng)(cheng)(cheng)(cheng)是由(you)機體的(de)炎(yan)癥反(fan)應(ying),膠原(yuan)合成(cheng)(cheng)(cheng)(cheng)(cheng)和降解不(bu)平衡(heng)引(yin)起(qi)的(de)異常(chang)(chang)粘多糖和肌(ji)(ji)成(cheng)(cheng)(cheng)(cheng)(cheng)纖維(wei)細(xi)(xi)(xi)胞(bao)(bao)(bao)的(de)增(zeng)殖(zhi)引(yin)起(qi)的(de)。一(yi)般(ban)來說,疤(ba)痕的(de)形成(cheng)(cheng)(cheng)(cheng)(cheng)是身(shen)體傷(shang)口(kou)修復的(de)必然(ran)結果。只(zhi)有當身(shen)體組(zu)織(zhi),特別是皮膚組(zu)織(zhi)被破壞到(dao)一(yi)定深度時,傷(shang)口(kou)才首先出現炎(yan)癥反(fan)應(ying),并且白細(xi)(xi)(xi)胞(bao)(bao)(bao)、巨噬細(xi)(xi)(xi)胞(bao)(bao)(bao)、肥(fei)大細(xi)(xi)(xi)胞(bao)(bao)(bao)浸潤并釋放。多種細(xi)(xi)(xi)胞(bao)(bao)(bao)因子(zi)),成(cheng)(cheng)(cheng)(cheng)(cheng)纖維(wei)細(xi)(xi)(xi)胞(bao)(bao)(bao)和肌(ji)(ji)成(cheng)(cheng)(cheng)(cheng)(cheng)纖維(wei)細(xi)(xi)(xi)胞(bao)(bao)(bao)增(zeng)殖(zhi)并合成(cheng)(cheng)(cheng)(cheng)(cheng)大量(liang)膠原(yuan)和基(ji)質,導致膠原(yuan)代謝(xie)和排列異常(chang)(chang),基(ji)質沉積異常(chang)(chang),微循環和自由(you)基(ji)因子(zi)。促進(jin)疤(ba)痕的(de)形成(cheng)(cheng)(cheng)(cheng)(cheng)。
