Utshintsho lwesakhiwo kunye ne-biochemical kwi-epidermal ekwaluphaleni kolusu

I-metabolism ye-epidermis kukuba i-basal keratinocytes inyuka kancinci kancinci ngokuhluka kweeseli, kwaye ekugqibeleni iyafa ukuze yenze i-non-nucleated stratum corneum, ize iwa. Ngokuqhelekileyo kukholelwa ukuba ngokwanda kobudala, umaleko we-basal kunye nomaleko we-spinous ziyaphazamiseka, ukudibana kwe-epidermis kunye ne-dermis kuba tyaba, kwaye ubukhulu be-epidermis buyancipha. Njengomqobo ongaphandle womzimba womntu, i-epidermis idibana ngqo nokusingqongileyo kwangaphandle kwaye ichaphazeleka lula zizinto ezahlukeneyo zangaphandle. Ukuguga kwe-epidermal kubonakalisa lula impembelelo yokuguga kunye nezinto zangaphandle ekwaluphaleni komntu.

Kwi-epidermis yolusu olugugayo, umahluko wobukhulu, imo kunye neempawu zokufaka imibala kwiiseli ze-basal layer ziyanda, ukudibana kwe-epidermis kunye ne-dermis kancinci kancinci kuyaba tyaba, uzipho lwe-epidermal luyaba nzulu, kwaye ubukhulu be-epidermal buyancipha. Ubukhulu be-epidermal buyehla malunga ne-6.4% kwishumi leminyaka, kwaye buyehla ngokukhawuleza nangakumbi kubasetyhini. Ubukhulu be-epidermal buyehla ngokukhula. Olu tshintsho lubonakala kakhulu kwiindawo ezivezwe, kubandakanya ubuso obungaphezulu kobuso, intamo, izandla kunye neengalo. Ii-Keratinocytes zitshintsha imilo njengoko ulusu luguga, luba lufutshane kwaye lutyebile, ngelixa ii-keratinocytes zikhula ngenxa yokutshintsha okufutshane kwe-epidermal, ixesha lokuvuselelwa kwe-epidermal yokuguga liyanda, umsebenzi wokwanda kweeseli ze-epidermal uyehla, kwaye i-epidermis iba ncinci., nto leyo ebangela ukuba ulusu lulahlekelwe bukuqina kunye nemibimbi.

Ngenxa yolu tshintsho lwemo, indawo edibanisa i-epidermis ne-dermis ayiqinanga kwaye ayichaphazeleki kumonakalo wangaphandle. Inani le-melanocytes liyehla kancinci emva kweminyaka engama-30, amandla okwanda ayancipha, kwaye umsebenzi we-enzymatic we-melanocytes uyancipha ngesantya se-8%-20% ngeshumi leminyaka. Nangona ulusu lungalula ukulujika lube mnyama, i-melanocytes ithambekele ekukhuleni kwendawo ukuze yenze amabala ombala, ingakumbi kwiindawo ezivezwe lilanga. Iiseli zeLangerhans nazo ziyancitshiswa, nto leyo eyenza ukuba ukusebenza komzimba wesikhumba kunciphe kwaye kube lula kwizifo ezosulelayo.

I-anlayzer yolusuLo matshini ungasetyenziselwa ukubona imibimbi yolusu lobuso, ubunjani balo, ukulahleka kwe-collagen, kunye nokwakheka kobuso ukunceda ekufumaneni ukwaluphala kolusu lobuso.
