Iimveliso

I-1) I-Collagen idlala indima ebalulekileyo kwinkqubo yokuphulukisa isilonda kunye nokwakheka kwesilonda.Ayinakusebenza nje njengesiseko se-elastic tissue kunye ne-adhesion substances, kodwa iphinda ivuselele ukuphuhliswa kweeseli, ukuhlukana, ukuhlukana kwezicubu kunye nokwanda, kunye nezicubu ezidibeneyo.Ukwahlula kunye nokwanda, Iyakwazi ukuvuselela i-capillary angiogenesis, ifake i-chemotaxis ye-monocytes kunye ne-fibroblasts, kwaye yondle kwaye ilawule izicubu ze-granulation.Ngokutsho kweengxelo, ukusetyenziswa kwe-collagen kunyango lwezilonda zolusu ezibangelwa yizizathu ezahlukeneyo kunempembelelo enhle, enokwenza i-ulcer surface kunye ne-epithelialization enzulu, ehambelana nokwakhiwa kwezicubu ze-granulation.(2) I-70% -80% yezinto eziphilayo emathanjeni yi-collagen.Xa amathambo enziwa, i-collagen fibers eyaneleyo kufuneka iqale idityaniswe ukuze yenze isakhelo samathambo.Ngoko ke, abanye abantu babiza i-collagen ithambo lamathambo.Imicu ye-collagen inokuqina okuqinileyo kunye nokunwebeka.Ukuba ithambo elide lifaniswa nekholamu ye-samente, ngoko iifayili ze-collagen ziyifreyimu yensimbi yekholomu, kwaye ukungabikho kwe-collagen kufana nokusetyenziswa kwentsimbi engaphantsi kwizakhiwo, kunye nobungozi bokuphuka nje ngobusuku.(3) Isiphumo se-collagen ekuphuculeni amabele kudala saziwa ngabantu.Amabele ubukhulu becala akhiwe zizicubu ezidibeneyo kunye nezicubu ze-adipose, ngelixa amabele amade, athe tye kwaye atyebileyo axhomekeke kakhulu kwinkxaso yezicubu ezixhumeneyo.I-Collagen iyona nxalenye ephambili yezicubu ezidibeneyo."I-Collagen isoloko isebenzisana neprotheni ye-polysaccharide kwi-tissue edibeneyo. Ihlanganiswe kwisakhiwo se-mesh ukuvelisa amandla athile omatshini, okuyisiseko sezinto eziphathekayo zokuxhasa ijika lomzimba womntu kunye nokubonakalisa ukuma okuthe tye."(4) I-Collagen ibizwa ngokuba "lithambo elingaphakathi kwethambo, ufele olungaphakathi kolusu, kunye nenyama ngaphakathi kwenyama"., kunokuthiwa yinkxaso eqinile ye-dermis, kwaye umphumo wayo eluswini uzibonakalisa.Ukukhuselwa kunye nokunwebeka okufanelekileyo: umaleko osezantsi we-epidermis, othatha uninzi lwesakhiwo ngumaleko wedermis, kunye nobukhulu obumalunga ne-2 mm, kwaye unokwahlulwa ube ngamanqwanqwa amathathu, angala, i-papillary layer, i-sub-papillary layer kunye umaleko we-reticular, uninzi lwawo luqulunqwe ziiproteni., Le nxalenye yeprotheni yenziwe nge-collagen kunye ne-elastin (i-elastin), enye i-nerve, i-capillaries, i-sweat and sebaceous glands, i-lymphatic vessels kunye neengcambu zeenwele.I-70% yamacandelo esikhumba ahlanganiswe ne-collagen.Ulusu lufana nomkhono omkhulu obopha onke amalungu omzimba, kwaye umphezulu mkhulu kakhulu.Xa izitho zomntu zihamba, i-collagen esikhumbeni isebenza, ukwenzela ukuba ulusu lunomsebenzi wokukhusela.I-Elasticity kunye nokuqina
