Mesebetsi ea Fisioloji eaThuto ea Microecology ea Letlalo
Limela tse tloaelehileng li na le botsitso bo matla 'me li ka thibela ho kolonea ha libaktheria tse tsoang linaheng tse ling. Maemong a tloaelehileng, ho bolokoa tekano e matla ea tikoloho pakeng tsa likokoana-hloko le likokoana-hloko, le pakeng tsa likokoana-hloko le beng ba tsona.
1. Kenya letsoho metabolism ea lisele tsa letlalo
Litšoelesa tsa sebaceous li ntša mafura, a fetoloang ke likokoana-hloko ho etsa filimi ea mafura e kopantsoeng. Lifilimi tsena tsa mafura li na le li-acid tse mafura tse lokolohileng, tse tsejoang hape e le lifilimi tsa asiti, tse ka fokotsang lintho tse nang le alkaline tse silafetseng letlalong le ho thibela libaktheria tse tsoang linaheng tse ling (tse fetisang libaktheria). ), li-fungus le likokoana-hloko tse ling tse bakang mafu lia hola, kahoo mosebetsi oa mantlha oa limela tse tloaelehileng tsa letlalo ke phello ea bohlokoa ea tšireletso.
2. Phepo e nepahetseng
Ha nako e ntse e ea, letlalo le na le bokhoni ba ho intlafatsa, 'me seo batho ba ka se bonang ka mahlo a hlobotseng ke dandruff, e leng phetoho e etsahalang butle-butle ea lisele tsa epidermal ho tloha ho keratinocyte e sebetsang le e nonneng ho ea ho lisele tse bataletseng tse sa sebetseng, ho nyamela ha li-organelle, le keratinization e etsahalang butle-butle. Lisele tsena tse kentsoeng keratin le tse ntšitsoeng lia qhalana ho ba phospholipids, amino acid, jj., tse ka sebelisoang bakeng sa kholo le ho monngoa ha baktheria ke lisele. Li-macromolecule tse qhalaneng li ke ke tsa monngoa ke letlalo, 'me li hloka ho senyeha tlas'a tšusumetso ea likokoana-hloko tsa letlalo hore e be lintho tse nyane tsa limolek'hule ho fepa letlalo.
3. Ho itšireletsa mafung
Jwalo ka mothapo wa pele wa tshireletso kgahlanong le dikokwana-hloko tse tswang kantle ho naha, letlalo la motho le sireletsa letlalo la motho ka mafolofolo kapa ka mokhoa o sa etseng letho ka mekgwa e fapaneng. E nngwe ya mekgwa ya bohlokwa ya tshireletso ena ke ho ntshuwa ha di-peptide tse thibelang dikokwana-hloko tse fumanehang ka hara letlalo la letlalo.
4. Ho itlhoekisa
Baktheria e lulang Propionibacterium le baktheria ea symbiotic Staphylococcus epidermidis letlalong la limela e bolisa sebum ho etsa li-fatty acid tse lokolohileng e le hore bokaholimo ba letlalo bo be boemong ba asiti hanyane, ke hore, filimi ea lipid e kopantsoeng le asiti, e ka hanyetsang ho kolone, kholo le ho ikatisa ha limela tse ngata tse fetang, tse kang Staphylococcus aureus, Streptococcus.
5. Phello ea thibelo
Microflora e tloaelehileng ke e 'ngoe ea lintlha tse sireletsang letlalo khahlanong le likokoana-hloko tse tsoang linaheng tse ling 'me hape ke karolo ea mosebetsi oa thibelo ea letlalo. Microbiota e kolobisitsoeng letlalong ka mokhoa o hlophisitsoeng le o hlophisehileng e tšoana le lera la biofilm, le sa bapaleng feela karolo ea ho sireletsa letlalo le pepeneneng la 'mele empa hape le ama ka kotloloho ho thehoa ha khanyetso ea ho kolonela, e le hore likokoana-hloko tse tsoang linaheng tse ling li se ke tsa fumana sebaka holim'a letlalo la 'mele.
