Yintoni indima ye-sebum membrane?

I-membrane ye-sebum inamandla kakhulu, kodwa ihlala ingahoywa. Ifilimu ye-sebum enempilo yinto yokuqala yesikhumba esinempilo, esikhanyayo. I-membrane ye-sebum inemisebenzi ebalulekileyo ye-physiological eluswini kunye nomzimba wonke, ngakumbi kule miba ilandelayo:

1. Isiphumo somqobo

Ifilimu ye-sebum yeyona nto ibalulekileyo yokugcina ukufuma kwesikhumba, enokuthi itshixe ngokufanelekileyo ukufuma, ithintele ukufuma okugqithisileyo kokufuma kwesikhumba, kunye nokuthintela ukufuma kwangaphandle kunye nezinto ezithile ekungeneni. Ngenxa yoko, ubunzima bolusu buhlala buqhelekileyo.

2. Fumisa ulusu

I-membrane ye-sebum ayiyonxalenye ethile yolusu. Ubukhulu becala iqulunqwe yi-sebum eveliswa ngamadlala e-sebaceous, i-lipids eveliswa ziikeratinocytes, kunye nokubila okukhutshwa ngamadlala okubila. Isasazwa ngokulinganayo phezu kwesikhumba kwaye yenza ifilimu yokukhusela yendalo ebusweni bolusu. . Inxalenye yayo ye-lipid ithambisa ulusu ngokufanelekileyo, igcina ulusu luthanjiswa kwaye londlekile, kwaye yenza ulusu lube bhetyebhetye, lugudileyo kwaye lubengezele; inxalenye enkulu kwifilimu ye-sebum inokugcina ulusu lufumile ukuya kwinqanaba elithile kwaye luthintele ukuqhekeka okomileyo.

3. Isiphumo esichasene nentsholongwane

I-pH ye-membrane ye-sebum iphakathi kwe-4.5 kunye ne-6.5, ene-asidi ebuthathaka. Le acidity ebuthathaka yenza ukuba ithintele ukukhula kwee-microorganisms ezifana neebhaktheriya kwaye ibe nefuthe lokuzihlambulula esikhumbeni, ngoko ke ngumaleko wokuzivikela kwi-immune surface.

Ukukhutshwa kwamadlala e-sebaceous kulawulwa ngamahomoni ahlukeneyo (afana ne-androgens, i-progesterone, i-estrogen, i-adrenal cortex hormones, i-hormone ye-pituitary, njl.), apho ukulawulwa kwe-androgens kukukhawulezisa ukwahlukana kweeseli ze-sebaceous gland, ukwandisa umthamo wabo. , kunye nokwandisa i-sebum synthesis; Kwaye i-estrogen inciphisa ukukhutshwa kwe-sebum ngokuthintela ngokungathanga ngqo ukuveliswa kwe-androgens engapheliyo, okanye isebenze ngokuthe ngqo kwi-sebaceous glands.

Ukuphuma kwe-sebum ngokugqithisileyo kunokubangela i-oyile, ulusu olurhabaxa, imingxunya eyandisiweyo, kwaye lula ukuba neengxaki zamaqhakuva. Ukukhutshwa okuncinci kakhulu kunokukhokelela esikhumbeni esomileyo, ukulinganisa, ukungabikho kwe-luster, ukuguga, njl.

Izinto ezichaphazela ukukhutshwa kwe-sebum zezi: i-endocrine, ubudala, isini, ubushushu, ukufuma, ukutya, umjikelezo we-physiological, iindlela zokucoca ulusu, njl.

Umhlalutyi wesikhumba weMeicetingasetyenziselwa ukubona ukuba inwebu ye-sebum isempilweni okanye hayi. Ukuba i-membrane ye-sebum incinci kakhulu, ngoko ke ulusu luya kuba lukhuni ngakumbi kwi-stimuli yangaphandle. Umfanekiso uya kudutshulwa phantsi kokukhanya kwe-cross-polarized kwaye ngokusekelwe kulo mfanekisoI-Meicetinkqubo isebenzisa algorithm ukufumana 3 imifanekiso- ubuntununtunu, indawo ebomvu, heatmap. Le mifanekiso ye-3 ingasetyenziselwa ukuhlalutya iingxaki zesikhumba ezinobuthathaka.
