The Physiological Ntchito za Skin Microecology

Physiological Ntchito zaSkin Microecology

Zomera zokhazikika zimakhala zokhazikika ndipo zimatha kuletsa kufalikira kwa mabakiteriya akunja. Nthawi zonse, kukhazikika kwachilengedwe kumasungidwa pakati pa tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda, komanso pakati pa tizilombo toyambitsa matenda ndi makamu.
1. Kuchita nawo kagayidwe ka minofu yapakhungu
Ma sebaceous glands amatulutsa lipids, omwe amapangidwa ndi tizilombo toyambitsa matenda kuti apange filimu ya emulsified lipid. Mafilimu a lipidwa ali ndi mafuta acids aulere, omwe amadziwikanso kuti mafilimu a asidi, omwe amatha kusokoneza zinthu zamchere zomwe zimayipitsidwa pakhungu ndikuletsa mabakiteriya akunja (mabakiteriya odutsa). ), bowa ndi tizilombo tina toyambitsa matenda timakula, choncho ntchito yaikulu ya zomera zapakhungu ndizofunika kwambiri zotetezera.
2. Zopatsa thanzi
Pakapita nthawi, khungu limatha kudzipanganso mwatsopano, ndipo zomwe anthu amatha kuwona ndi maso ndi dandruff, ndiko kusintha kwapang'onopang'ono kwa maselo a epidermal kuchokera ku keratinocyte yogwira ndi yochulukira kukhala maselo osagwira ntchito, kutha kwa organelles, ndi pafupipafupi keratinization. Maselo opangidwa ndi keratinized ndi exfoliated amawonongeka kukhala phospholipids, amino acid, ndi zina zotero, zomwe zingagwiritsidwe ntchito pakukula kwa bakiteriya ndi kuyamwa ndi maselo. Ma macromolecules osokonekera sangathe kutengeka ndi khungu, ndipo amafunika kunyozedwa pansi pa zochita za tizilombo tating'onoting'ono tomwe timakhala tinthu tating'onoting'ono tomwe timadyetsa khungu.
3. Chitetezo
Monga mzere woyamba wa chitetezo ku tizilombo toyambitsa matenda achilendo, khungu la munthu mwachangu kapena mwapang'onopang'ono limateteza khungu la khamu kudzera m'njira zosiyanasiyana. Imodzi mwa njira zofunika kwambiri zodzitetezera izi ndi kutulutsa kwa ma peptides antimicrobial omwe amapezeka mu epidermis.
4. Kudziyeretsa
The okhala mabakiteriya Propionibacterium ndi symbiotic mabakiteriya Staphylococcus epidermidis pakhungu zomera kuwola sebum kupanga ufulu mafuta zidulo kuti khungu pamwamba ndi pang'ono acidic, ndiko kuti, ndi acidic emulsified lipid filimu, amene akhoza antagonised colonization, kukula, ndi kuberekana kwa zomera zambiri zomwe zimadutsa, monga Staphylococcus aureus, Streptococcus.
5. Cholepheretsa zotsatira
Microflora yachibadwa ndi imodzi mwazinthu zomwe zimateteza khungu ku tizilombo toyambitsa matenda achilendo komanso ndi gawo la ntchito yotchinga khungu. Ma microbiota omwe amakhala pakhungu mwadongosolo komanso mwadongosolo ali ngati gawo la biofilm, lomwe silimangothandiza kuteteza epidermis yowonekera m'thupi komanso kumakhudza mwachindunji kukhazikitsidwa kwa kukana kwa atsamunda, kotero kuti tizilombo toyambitsa matenda akunja sangathe kupeza phazi mu thupi khungu pamwamba.
