Imisebenzi yePhysiological ofI-Skin Microecology
I-flora evamile inokuzinza okuqinile futhi ingavimbela ukuhlangana kwamabhaktheriya angaphandle. Ngaphansi kwezimo ezijwayelekile, ibhalansi eguquguqukayo yemvelo iyagcinwa phakathi kwama-microorganisms nama-microorganisms, naphakathi kwama-microorganisms nabasingathi.
1. Bamba iqhaza kumetabolism yezicubu zesikhumba
Izindlala ze-sebaceous zikhiqiza ama-lipids, agaywa ama-microorganisms ukuze enze ifilimu ye-lipid emulsified. Lawa mafilimu e-lipid aqukethe ama-fatty acids mahhala, aziwa nangokuthi amafilimu ane-asidi, anganciphisa izinto ze-alkaline ezingcoliswe esikhumbeni futhi avimbele amagciwane angaphandle (amagciwane adlulayo). ), isikhunta namanye ama-microorganisms e-pathogenic akhula, ngakho-ke umsebenzi oyinhloko wezitshalo zesikhumba ezivamile kuwumphumela obalulekile wokuvikela.
2. Umphumela wokudla okunomsoco
Ngokuhamba kwesikhathi, isikhumba sinamandla okuzivuselela, futhi lokho abantu abangakubona ngeso lenyama kuwukuqunjelwa, okuwukuguqulwa kancane kancane kwamangqamuzana e-epidermal asuka kuma-keratinocyte asebenzayo naphuphile abe amangqamuzana ayisicaba angasebenzi, ukunyamalala kwama-organelles, kanye ne-epidermal cell. keratinization kancane kancane. Lawa maseli e-keratinized kanye nama-exfoliated ahlakazeka abe ama-phospholipids, ama-amino acid, njll., angasetshenziselwa ukukhula kwamagciwane kanye nokumuncwa ngamaseli. Ama-macromolecules ahlakazekile awakwazi ukumuncwa isikhumba, futhi adinga ukucekelwa phansi ngaphansi kwesenzo sama-microorganisms esikhumba ukuze abe yizinto ezincane zamangqamuzana ukondla isikhumba.
3. Ukuzivikela komzimba
Njengomugqa wokuqala wokuzivikela kuma-pathogens angaphandle, isikhumba somuntu sivikela isikhumba somsingathi ngezinqubo ezihlukahlukene. Enye yezindlela ezibalulekile zalokhu kuzivikela ukukhiqizwa kwama-peptide e-antimicrobial atholakala ku-epidermis.
4. Ukuzihlanza
Amagciwane ahlala e-Propionibacterium kanye ne-symbiotic bacteria i-Staphylococcus epidermidis esitshalweni sesikhumba abola i-sebum yakhe ama-fatty acids amahhala ukuze ubuso besikhumba bube sesimweni esine-acidic kancane, okungukuthi, ifilimu ye-acidic emulsified lipid, engaphikisana nekoloni, ukukhula, kanye. ukukhiqizwa kwezitshalo eziningi ezidlulayo, njengeStaphylococcus aureus, Streptococcus.
5. Umphumela wokuvimbela
I-microflora evamile ingenye yezinto ezivikela isikhumba kuma-pathogens angaphandle futhi iyingxenye yomsebenzi wokuvimbela isikhumba. I-microbiota ehlanganiswe esikhumbeni ngendlela ehlelekile futhi ehlelekile ifana nongqimba lwe-biofilm, olungagcini nje ukudlala indima ekuvikeleni i-epidermis esobala yomzimba kodwa futhi ithinte ngokuqondile ukusungulwa kokumelana nekoloni, ukuze amagciwane angaphandle angakwazi ukuthola izinyawo endaweni yesikhumba somzimba.
