Imisebenzi yePhysiological yeI-Microecology yolusu
Iintyatyambo eziqhelekileyo zizinzile kwaye zinokuthintela ukungena kweebhaktheriya zangaphandle. Phantsi kweemeko eziqhelekileyo, ulungelelwaniso oluguquguqukayo lwendalo luyagcinwa phakathi kwee-microorganisms kunye nee-microorganisms, kunye naphakathi kwee-microorganisms kunye neehostele.
1. Thatha inxaxheba kwi-metabolism yezicubu zolusu
Ii-sebaceous glands zikhupha ii-lipids, ezithi zigaywe zii-microorganisms ukuze zenze i-lipid film ehlanganisiweyo. Ezi lipid films ziqulathe ii-fatty acids zasimahla, ezaziwa ngokuba zii-acid films, ezinokuthomalalisa izinto ze-alkaline ezingcoliswe eluswini kwaye zithintele iintsholongwane zangaphandle (ezidlula iibhaktheriya). ), iifungi kunye nezinye ii-microorganisms ezibangela izifo ziyakhula, ngoko ke umsebenzi oyintloko wezityalo zesikhumba eziqhelekileyo ngumphumo obalulekileyo wokukhusela.
2. Isiphumo sesondlo
Ekuhambeni kwexesha, ulusu luyakwazi ukuzihlaziya, kwaye into abantu abanokuyibona ngamehlo enyama yi-dandruff, ethetha ukuguqulwa kancinci kancinci kweeseli ze-epidermal ukusuka kwi-keratinocytes ezisebenzayo nezityebileyo zibe ziiseli ezingenanto, ukunyamalala kwee-organelles, kunye ne-keratinization kancinci kancinci. Ezi seli ze-keratinized nezikhutshiweyo ziyaqhekeka zibe yi-phospholipids, ii-amino acids, njl.njl., ezinokusetyenziselwa ukukhula kwebhaktheriya kunye nokufunxwa ziiseli. Ii-macromolecules eziqhekekileyo azinakufunxwa lusu, kwaye kufuneka zonakaliswe phantsi kwesenzo seentsholongwane zesikhumba ukuze zibe zizinto ezincinci ze-molecular zokondla ulusu.
3. Ukuzikhusela komzimba
Njengomgca wokuqala wokuzikhusela kwiintsholongwane zangaphandle, ulusu lomntu lukhusela ulusu lomntu ngokukhutheleyo okanye ngokungakhathaliyo ngeendlela ezahlukeneyo. Enye yeendlela ezibalulekileyo zokuzikhusela kukukhupha iipeptides ezilwa neentsholongwane ezikwi-epidermis.
4. Ukuzihlambulula
Iibhaktheriya ezihlala apho iPropionibacterium kunye nebhaktheriya ye-symbiotic iStaphylococcus epidermidis kulusu lwezityalo zibola i-sebum ukuze zenze ii-fatty acids zasimahla ukuze umphezulu wolusu ube kwimeko ye-asidi encinci, oko kukuthi, ifilimu ye-lipid emulsified acidic, enokuthi ithintele ukuhlanganiswa, ukukhula, kunye nokuzala kwezityalo ezininzi ezidlulayo, ezifana neStaphylococcus aureus, iStreptococcus.
5. Isiphumo somqobo
I-microflora eqhelekileyo yenye yezinto ezikhusela ulusu kwiintsholongwane zangaphandle kwaye ikwayinxalenye yomsebenzi wokuthintela ulusu. I-microbiota ehlala eluswini ngendlela ehlelekileyo nehambelanayo ifana nomaleko we-biofilm, ongadlali nje kuphela indima ekukhuseleni i-epidermis ebonakalayo yomzimba kodwa ikwachaphazela ngokuthe ngqo ukusekwa kokumelana nokukhula kwe-colonization, ukuze iintsholongwane zangaphandle zingakwazi ukufumana indawo kumphezulu wolusu lomzimba.
