Mesebetsi ea Fisioloji eaMicroecology ea Letlalo
Limela tse tloaelehileng li na le botsitso bo matla ba ho ikemela 'me li ka thibela bokolone ba libaktheria tse tsoang linaheng tse ling. Tlas'a maemo a tloaelehileng, ho bolokoa tekano e matla ea tikoloho pakeng tsa likokoana-hloko le likokoana-hloko, le pakeng tsa likokoana-hloko le lihlopha.
1. Kenya letsoho ho metabolism ea lisele tsa letlalo
Litšoelesa tsa sebaceous li hlahisa lipids, tse hlahisoang ke likokoana-hloko ho etsa filimi ea emulsified lipid. Lifilimi tsena tsa lipid li na le li-acid tse sa lefelloeng tsa mafura, tse tsejoang hape e le lifilimi tsa acid, tse ka fokotsang lintho tsa alkaline tse silafetseng letlalong le ho thibela libaktheria tsa kantle ho naha (libaktheria tse fetang). ), li-fungus le likokoana-hloko tse ling tsa pathogenic lia hōla, kahoo mosebetsi o ka sehloohong oa limela tse tloaelehileng tsa letlalo ke phello ea bohlokoa ea tšireletso.
2. Phello ea phepo e nepahetseng
Ha nako e ntse e ea, letlalo le na le bokhoni ba ho inchafatsa, 'me seo batho ba ka se bonang ka mahlo ke dandruff, e leng phetoho ea butle-butle ea lisele tsa epidermal ho tloha ho keratinocyte e sebetsang le e teteaneng ho ea lisele tse bataletseng tse sa sebetseng, ho nyamela ha organelles, le keratinization ea butle-butle. Lisele tsena tse keratinized le exfoliated li arotsoe ka phospholipids, amino acid, joalo-joalo, e ka sebelisoang bakeng sa kholo ea baktheria le ho monya lisele. Li-macromolecules tse arohaneng li ke ke tsa kenngoa ke letlalo, 'me li hloka ho senyeha tlas'a ketso ea likokoana-hloko tsa letlalo ho fetoha lintho tse nyenyane tsa limolek'hule ho fepa letlalo.
3. Ho itšireletsa mafung
E le mokhoa oa pele oa tšireletso khahlanong le likokoana-hloko tse tsoang linaheng tse ling, letlalo la motho le sireletsa letlalo la moeti ka mekhoa e sa tšoaneng. E 'ngoe ea mekhoa ea bohlokoa ea mokhoa ona oa ho itšireletsa ke ho hlahisa li-peptide tse thibelang likokoana-hloko tse hlahang ka har'a epidermis.
4. Ho itlhoekisa
Libaktheria tse lulang Propionibacterium le libaktheria tsa symbiotic Staphylococcus epidermidis letlalong la limela li bola sebum ho theha mafura a mafura a mahala e le hore letlalo le be boemong ba acidic hanyane, ke hore, filimi e nang le acidic emulsified lipid, e ka hanyetsang bokolone, kholo le kholo. ho ikatisa ha limela tse ngata tse fetang, joalo ka Staphylococcus aureus, Streptococcus.
5. Phello ea thibelo
Microflora e tloaelehileng ke e 'ngoe ea lintho tse sireletsang letlalo khahlanong le likokoana-hloko tse tsoang linaheng tse ling hape ke karolo ea mosebetsi oa thibelo ea letlalo. The microbiota colonized holim'a letlalo ka mokhoa o phahameng le o hlophisehileng o tšoana le lera la biofilm, e seng feela karolo ea ho sireletsa li-epidermis tse pepeneneng tsa 'mele empa hape e ama ka ho toba ho thehoa ha ho hanyetsa likolone, e le hore likokoana-hloko tse tsoang linaheng tse ling li se ke tsa fumana foothold ka bokahodimo ba letlalo la mmele.
