Physiological Functions ntawmDaim tawv nqaij Microecology
Cov nroj tsuag ib txwm muaj kev ruaj khov rau tus kheej thiab tuaj yeem tiv thaiv cov kab mob txawv teb chaws.Nyob rau hauv ib txwm muaj xwm txheej, qhov sib npaug ntawm ecological tshuav nyiaj li cas yog tswj hwm ntawm cov kab mob thiab cov kab mob, thiab ntawm cov kab mob thiab cov tswv.
1. Koom tes hauv daim tawv nqaij metabolism
Cov qog sebaceous secrete lipids, uas yog metabolized los ntawm cov kab mob kom tsim tau emulsified lipid zaj duab xis.Cov lipid films no muaj cov roj fatty acids dawb, tseem hu ua acid films, uas tuaj yeem ua rau cov tshuaj alkaline tsis huv ntawm daim tawv nqaij thiab tiv thaiv cov kab mob txawv teb chaws (cov kab mob kis mus).), fungi thiab lwm yam kab mob pathogenic microorganisms loj hlob, yog li lub luag haujlwm tseem ceeb ntawm cov tawv nqaij ib txwm muaj yog qhov tseem ceeb tiv thaiv cov nyhuv.
2. Kev noj zaub mov zoo
Nyob rau tib lub sijhawm, daim tawv nqaij muaj peev xwm rov ua dua nws tus kheej, thiab qhov uas tib neeg tuaj yeem pom ntawm qhov muag liab qab yog dandruff, uas yog maj mam hloov pauv ntawm cov cell epidermal los ntawm cov nquag thiab plump keratinocytes mus rau hauv cov hlwb tsis muaj zog, ploj ntawm cov organelles, thiab gradual keratinization.Cov keratinized thiab exfoliated hlwb yog disintegrated rau hauv phospholipids, amino acids, thiab lwm yam, uas yuav siv tau rau cov kab mob loj hlob thiab nqus los ntawm cov hlwb.Lub disintegrated macromolecules tsis tuaj yeem nqus los ntawm daim tawv nqaij, thiab yuav tsum tau degraded nyob rau hauv qhov kev txiav txim ntawm cov kab mob ntawm daim tawv nqaij kom dhau los ua cov khoom me me los txhawb cov tawv nqaij.
3. Kev tiv thaiv
Raws li thawj kab ntawm kev tiv thaiv tawm tsam cov kab mob txawv teb chaws, tib neeg cov tawv nqaij nquag los yog tiv thaiv cov tawv nqaij los ntawm ntau yam txheej txheem.Ib qho ntawm cov txheej txheem tseem ceeb ntawm kev tiv thaiv tus kheej no yog kev tso tawm ntawm cov tshuaj tiv thaiv kab mob peptides uas muaj nyob hauv daim tawv nqaij.
4. Kev ntxuav tus kheej
Cov kab mob nyob hauv Propionibacterium thiab cov kab mob symbiotic Staphylococcus epidermidis nyob rau hauv daim tawv nqaij flora decompose sebum los tsim cov fatty acids dawb kom cov tawv nqaij nto nyob rau hauv ib tug me ntsis acidic xeev, uas yog, ib tug acidic emulsified lipid zaj duab xis, uas yuav antagonize lub colonization, kev loj hlob, thiab Kev loj hlob ntawm ntau cov nroj tsuag, xws li Staphylococcus aureus, Streptococcus.
5. Kev cuam tshuam
Cov microflora ib txwm yog ib qho ntawm cov yam ntxwv uas tiv thaiv daim tawv nqaij tiv thaiv kab mob txawv teb chaws thiab kuj yog ib feem ntawm daim tawv nqaij barrier muaj nuj nqi.Lub microbiota colonized ntawm daim tawv nqaij nyob rau hauv ib tug hierarchical thiab kev coj noj coj ua yog zoo li ib tug txheej ntawm biofilm, uas tsis tsuas yog plays lub luag hauj lwm nyob rau hauv kev tiv thaiv ntawm exposed epidermis ntawm lub cev tab sis kuj ncaj qha cuam tshuam rau lub tsim ntawm colonization kuj, yog li ntawd txawv teb chaws pathogens tsis tau txais ib tug. foothold nyob rau hauv lub cev ntawm daim tawv nqaij nto.
