Cov Haujlwm ntawm Lub Cev ntawm Daim Tawv Nqaij Microecology

Cov Haujlwm ntawm Lub CevKev Tshawb Fawb Txog Kab Mob Ntawm Tawv Nqaij

Cov kab mob ib txwm muaj kev ruaj khov thiab tuaj yeem tiv thaiv kev loj hlob ntawm cov kab mob txawv teb chaws. Nyob rau hauv qhov xwm txheej ib txwm muaj, kev sib npaug ntawm cov kab mob me me thiab cov kab mob me me, thiab ntawm cov kab mob me me thiab cov tswv tsev.
1. Koom nrog cov txheej txheem ntawm daim tawv nqaij
Cov qog sebaceous tso cov lipids, uas cov kab mob me me metabolized los tsim cov lipid zaj duab xis emulsified. Cov lipid zaj duab xis no muaj cov roj fatty acids dawb, tseem hu ua acid zaj duab xis, uas tuaj yeem neutralize alkaline cov tshuaj muaj kuab paug rau ntawm daim tawv nqaij thiab tiv thaiv cov kab mob txawv teb chaws (cov kab mob hla dhau). ), fungi thiab lwm yam kab mob pathogenic loj hlob, yog li lub luag haujlwm tseem ceeb ntawm cov kab mob ntawm daim tawv nqaij ib txwm yog qhov tseem ceeb tiv thaiv.
2. Cov txiaj ntsig ntawm kev noj haus
Raws li lub sijhawm dhau mus, daim tawv nqaij muaj peev xwm rov ua dua tshiab, thiab qhov uas tib neeg pom nrog lub qhov muag liab qab yog dandruff, uas yog qhov hloov pauv maj mam ntawm cov hlwb epidermal los ntawm cov keratinocytes nquag thiab plump mus rau hauv cov hlwb tiaj tus tsis ua haujlwm, qhov ploj ntawm organelles, thiab maj mam keratinization. Cov hlwb keratinized thiab exfoliated no tau tawg ua phospholipids, amino acids, thiab lwm yam, uas tuaj yeem siv rau kev loj hlob ntawm cov kab mob thiab kev nqus los ntawm cov hlwb. Cov macromolecules tawg tsis tuaj yeem nqus los ntawm daim tawv nqaij, thiab yuav tsum tau degraded nyob rau hauv kev ua ntawm cov kab mob me me ntawm daim tawv nqaij kom dhau los ua cov khoom me me molecular los pub rau daim tawv nqaij.
3. Kev tiv thaiv kab mob
Ua ib txoj kab tiv thaiv thawj zaug tiv thaiv cov kab mob txawv teb chaws, tib neeg daim tawv nqaij tiv thaiv tus tswv tsev daim 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 cov tshuaj tua kab mob peptides uas muaj nyob hauv daim tawv nqaij epidermis.
4. Kev ntxuav tus kheej
Cov kab mob Propionibacterium thiab cov kab mob symbiotic Staphylococcus epidermidis hauv cov tawv nqaij flora decompose sebum los tsim cov roj fatty acids dawb kom qhov chaw ntawm daim tawv nqaij nyob rau hauv ib qho acidic xeev, uas yog, ib tug acidic emulsified lipid zaj duab xis, uas tuaj yeem antagonize lub colonization, kev loj hlob, thiab kev tsim ntawm ntau cov kab mob hla, xws li Staphylococcus aureus, Streptococcus.
5. Cov teebmeem thaiv kev cuam tshuam
Cov kab mob me me uas nyob hauv daim tawv nqaij yog ib qho ntawm cov yam tseem ceeb uas tiv thaiv daim tawv nqaij ntawm cov kab mob txawv teb chaws thiab kuj yog ib feem ntawm kev ua haujlwm ntawm daim tawv nqaij. Cov kab mob me me uas nyob hauv daim tawv nqaij zoo li ib txheej biofilm, uas tsis yog tsuas yog ua lub luag haujlwm tiv thaiv cov epidermis uas raug nthuav tawm ntawm lub cev xwb tab sis kuj cuam tshuam ncaj qha rau kev tsim kom muaj kev tiv thaiv kev loj hlob, yog li cov kab mob txawv teb chaws tsis tuaj yeem nkag mus rau hauv lub cev daim tawv nqaij.
