The Physiological Mabasa eSkin Microecology
Iyo yakajairika flora ine yakasimba kugadzikana uye inogona kudzivirira colonization yekunze mabhakitiriya. Mumamiriro ezvinhu akajairwa, kusimba kwezvakatipoteredza kunochengetedzwa pakati pezvipembenene nema microorganisms, uye pakati pema microorganisms uye mauto.
1. Kutora chikamu mune ganda tishu metabolism
Iyo sebaceous glands inoburitsa lipids, iyo inogadziriswa nema microorganisms kuti iite emulsified lipid firimu. Aya lipid mafirimu ane emahara fatty acids, anozivikanwawo semafirimu easidhi, anogona kudzikamisa alkaline zvinhu zvakasvibiswa paganda uye kuvharisa mabhakitiriya ekunze (kupfuura mabhakitiriya). ), fungi uye mamwe pathogenic microorganisms anokura, saka basa rekutanga rezvakajairwa maruva eganda chinhu chakakosha chekudzivirira.
2. Nutritional effect
Nekufamba kwenguva, ganda rinokwanisa kuzvivandudza, uye izvo vanhu vanogona kuona neziso rakashama ndeye dandruff, kunova kushanduka zvishoma nezvishoma kwemasero epidermal kubva kune anoshanda uye akapfava keratinocytes kuita isingashande sandara maseru, kunyangarika kwe organelles, uye zvishoma nezvishoma keratinization. Aya keratinized uye exfoliated masero akaparadzaniswa kuita phospholipids, amino acids, nezvimwewo, inogona kushandiswa pakukura kwebhakitiriya uye kutorwa nemasero. Iyo yakaparadzaniswa macromolecules haigone kutorwa neganda, uye inoda kuderedzwa pasi pechiito cheganda tupukanana kuti ive diki mamorekuru zvinhu kuti zvifudze ganda.
3. Immunity
Sezvo mutsara wekutanga wekudzivirira kubva kune dzimwe nyika zvirwere, ganda revanhu rinoshingaira kana kuti risingaiti rinodzivirira ganda rinogamuchira kuburikidza nemhando dzakasiyana-siyana. Imwe yenzira dzakakosha dzekuzvidzivirira uku ndiko kuburitswa kweantimicrobial peptides inherent in epidermis.
4. Kuzvichenura
Hutachiona hunogara Propionibacterium uye symbiotic bacteria Staphylococcus epidermidis paganda flora inoora sebum kuti iumbe mahara fatty acids kuitira kuti ganda repamusoro rive mune zvishoma asidhi, kureva, ane acidic emulsified lipid film, inogona kupikisa colonization, kukura, uye. kuberekana kwemaruva akawanda anopfuura, akadai seStaphylococcus aureus, Streptococcus.
5. Barrier effect
Iyo yakajairika microflora ndechimwe chezvinhu zvinodzivirira ganda kubva kune ekunze hutachiona uye zvakare chikamu cheganda barriers basa. Iyo microbiota yakakomberedzwa paganda nenzira ine hierarchical uye yakarongeka yakafanana nedhizaini yebiofilm, iyo isingangoite basa mukudzivirira yakafumurwa epidermis yemuviri asiwo inokanganisa zvakananga kugadzwa kwe colonization kuramba, kuitira kuti hutachiona hwekunze husakwanise kuwana kutsika mukati meganda remuviri.
