Imisebenzi Yomzimba Ka-I-Microecology Yesikhumba
Izitshalo ezivamile zinokuzimela okuqinile futhi zingavimbela ukuqongelela kwamagciwane angaphandle. Ngaphansi kwezimo ezijwayelekile, ibhalansi eguquguqukayo yemvelo iyagcinwa phakathi kwamagciwane amancane namagciwane amancane, naphakathi kwamagciwane amancane nabanikazi bawo.
1. Bamba iqhaza ekugayweni kwezicubu zesikhumba
Izindlala ze-sebaceous zikhipha ama-lipid, aguqulwa yizinto ezincane ukuze zakhe ifilimu yamafutha ehlanganisiwe. Lawa ma-lipid aqukethe ama-fatty acid amahhala, aziwa nangokuthi ama-acid film, angaqeda izinto ze-alkaline ezingcoliswe esikhumbeni futhi avimbele amabhaktheriya angaphandle (adlula amabhaktheriya). ), isikhunta kanye nezinye izinto ezincane ezibangela izifo ziyakhula, ngakho-ke umsebenzi oyinhloko wezitshalo zesikhumba ezivamile uwumphumela obalulekile wokuvikela.
2. Umphumela wokudla okunempilo
Ngokuhamba kwesikhathi, isikhumba sinekhono lokuzivuselela, futhi lokho abantu abangakubona ngamehlo enyama yi-dandruff, okuwukuguqulwa kancane kancane kwamaseli e-epidermal kusuka kuma-keratinocyte asebenzayo naqothukile abe amaseli ayisicaba angasebenzi, ukunyamalala kwama-organelle, kanye ne-keratinization kancane kancane. Lawa maseli aqothulwe futhi akhishwe emaqabungeni ahlakazeka abe ama-phospholipid, ama-amino acid, njll., angasetshenziswa ekukhuleni nasekumuncweni kwamagciwane ngamaseli. Ama-macromolecule aqothukile awakwazi ukumuncwa yisikhumba, futhi adinga ukuwohloka ngaphansi kwesenzo sama-microorganisms esikhumba ukuze abe izinto ezincane zama-molecule ukuze ondle isikhumba.
3. Ukungavikeleki komzimba
Njengomugqa wokuqala wokuzivikela ezifweni zamagciwane zakwamanye amazwe, isikhumba somuntu sivikela isikhumba somuntu ngenkuthalo noma ngokunganaki ngezindlela ezahlukahlukene. Enye yezindlela ezibalulekile zalokhu kuzivikela ukukhishwa kwama-peptide alwa namagciwane atholakala ku-epidermis.
4. Ukuzihlanza
Ibhaktheriya elihlala khona i-Propionibacterium kanye nebhaktheriya elihambisanayo i-Staphylococcus epidermidis esikhumbeni ibolisa i-sebum ukuze yakhe ama-fatty acid amahhala ukuze ubuso besikhumba bube sesimweni se-acidic kancane, okungukuthi, ifilimu ye-lipid emulsified acidic, engamelana nokwakheka, ukukhula, kanye nokuzala kwezitshalo eziningi ezidlulayo, njenge-Staphylococcus aureus, i-Streptococcus.
5. Umphumela wesithiyo
I-microflora evamile ingenye yezinto ezivikela isikhumba ezifweni zangaphandle futhi iyingxenye yomsebenzi wokuvimbela isikhumba. I-microbiota ehlala esikhumbeni ngendlela ehlelekile nehlelekile ifana nongqimba lwe-biofilm, olungagcini nje ngokudlala indima ekuvikeleni i-epidermis eveziwe yomzimba kodwa futhi oluthinta ngqo ukumiswa kokumelana nokwakheka kwe-colonization, ukuze amagciwane angaphandle angakwazi ukuthola indawo ebusweni besikhumba somzimba.
