Imisebenzi yePhysiology yeI-Skin Microecology

I-flora eqhelekileyo inokuzinza okuqinileyo kwaye inokuthintela ikholoni yeebhaktheriya zangaphandle. Kwiimeko eziqhelekileyo, ibhalansi ye-ecological eguquguqukayo igcinwa phakathi kwe-microorganisms kunye ne-microorganisms, naphakathi kwe-microorganisms kunye nemikhosi.
1. Thatha inxaxheba kwi-metabolism yezicubu zesikhumba
Iingqungquthela ze-sebaceous zikhupha i-lipids, ezixutywe nge-microorganisms ukwenza ifilimu ye-lipid emulsified. Ezi filimu ze-lipid ziqulethe i-fatty acids yamahhala, eyaziwa ngokuba ziifilimu ze-asidi, ezinokuthi zithintele izinto ze-alkaline ezingcolileyo esikhumbeni kwaye zithintele iibhaktheriya zangaphandle (iibhaktheriya ezidlulayo). ), i-fungi kunye nezinye ii-microorganisms ze-pathogenic zikhula, ngoko ke umsebenzi oyintloko wezityalo eziqhelekileyo zesikhumba yimpembelelo ebalulekileyo yokukhusela.
2. Isiphumo sesondlo
Ngokuhamba kwexesha, ulusu lunamandla okuzihlaziya, kwaye into ebonwa ngabantu ngeliso lenyama yidandruff, olu lutshintsho oluthe ngcembe lweeseli ze-epidermal ukusuka kwi-keratinocyte esebenzayo kunye netyebileyo ukuya kwiiseli ezisicaba ezingasebenziyo, ukunyamalala kwe-organelles, kunye keratinization ngokuthe ngcembe. Ezi ziseli ze-keratinized kunye ne-exfoliated zichithwa kwi-phospholipids, i-amino acids, njl., Engasetyenziselwa ukukhula kwebhaktheriya kunye nokufunxa ngamaseli. I-macromolecules edibeneyo ayinakuxutywa ngesikhumba, kwaye kufuneka ihlanjululwe phantsi kwesenzo se-microorganisms yesikhumba ukuba ibe zizinto ezincinci ze-molecular zondla ulusu.
3. Ukunganyangeki
Njengomgca wokuqala wokukhusela kwi-pathogens yangaphandle, ulusu lomntu ngokusebenzayo okanye ngokungaqhelekanga lukhusela ulusu lomkhosi ngokusebenzisa iindlela ezahlukeneyo. Enye yeendlela ezibalulekileyo zokuzikhusela kukukhutshwa kwe-peptides ye-antimicrobial ekhoyo kwi-epidermis.
4. Ukuzihlambulula
Ibhaktheriya ehlala iPropionibacterium kunye nebhaktiriya ye-symbiotic i-Staphylococcus epidermidis kwiflora yolusu ibolisa i-sebum ukuze yenze i-acids enamafutha asimahla ukuze umphezulu wolusu ubekwimeko ene-acidic kancinane, oko kukuthi, ifilimu ene-acidic emulsified lipid, enokumelana ne-colonization, ukukhula, kunye ukuveliswa kwezityalo ezininzi ezidlulayo, ezifana neStaphylococcus aureus, iStreptococcus.
5. Isiphumo somqobo
I-microflora eqhelekileyo yenye yezinto ezikhusela ulusu kwii-pathogens zangaphandle kwaye ziyinxalenye yomsebenzi wokuthintela ulusu. I-microbiota egcinwe eluswini ngendlela enocwangco kunye nocwangco ifana nomaleko we-biofilm, engadlali kuphela indima ekukhuseleni i-epidermis ebonakalayo yomzimba kodwa ichaphazela ngokuthe ngqo ukusekwa kokumelana nekoloni, ukuze iintsholongwane zangaphandle zingakwazi ukufumana inyawo kwindawo yolusu lomzimba.
