Iyo sebum membrane ine simba kwazvo, asi inogara ichifuratirwa. Firimu ine hutano sebum ndiyo yekutanga yehutano, ganda rakajeka. Iyo sebum membrane ine yakakosha physiological mabasa paganda uye kunyangwe muviri wese, kunyanya mune zvinotevera zvinhu:
1. Barrier effect
Iyo sebum firimu ndiyo inonyanya kukosha yekuchengeta hunyoro hweganda, iyo inogona kunyatso kukiya unyoro, kudzivirira yakawandisa evaporation yehunyoro hweganda, uye kudzivirira huwandu hukuru hwekunze hunyoro uye zvimwe zvinhu kubva pakupinda. Somugumisiro, uremu hweganda hunoramba huri hwemazuva ose.
2. Nyoresa ganda
Sebum membrane haisi yeimwe ganda reganda. Inonyanya kuumbwa sebum yakavanzwa ne sebaceous glands, lipids inogadzirwa nekeratinocytes, uye dikita rakavanzwa nedikita glands. Inoparadzirwa zvakaenzana pamusoro peganda uye inoumba firimu rekudzivirira rechisikiro pamusoro peganda. . Iyo lipid chikamu inonyatso kunyorovesa ganda, inoita kuti ganda rive nemafuta uye nekudya, uye rinoita kuti ganda rishanduke, rakatsetseka uye richipenya; chikamu chikuru mufirimu ye sebum inogona kuchengetedza ganda rakanyorova kune imwe nhanho uye kudzivirira kuputika kwakaoma.
3. Anti-infective effect
Iyo pH ye sebum membrane iri pakati pe4.5 ne6.5, iyo isina kusimba acidic. Iyi acidity isina simba inoita kuti inhibisa kukura kwehutachiona hwakadai sebhakitiriya uye ine kuzvichenesa paganda, saka ndiyo immune layer paganda.
Kudzivirirwa kwesebaceous glands kunodzorwa neakasiyana mahomoni (akadai se androgens, progesterone, estrogen, adrenal cortex mahomoni, pituitary mahomoni, nezvimwewo), pakati peiyo mutemo we androgens ndeye kukurumidza kupatsanurwa kwesebaceous gland masero, kuwedzera huwandu hwavo. uye kuwedzera sebum synthesis; Uye estrogen inoderedza sebum secretion nekudzivisa nenzira isina kunanga kugadzirwa kwe endogenous androgens, kana zvakananga kuita pane sebaceous glands.
Kuwedzera sebum secretion kunogona kukonzera mafuta, ganda rakakasharara, mapores akakurisa, uye anowanzo kurwara nedambudziko. Kunyanya kuvharidzira kunogona kutungamira kune yakaoma ganda, kuyera, kushaikwa kwekupenya, kuchembera, nezvimwe.
Zvinhu zvinokanganisa sebum secretion ndezvi: endocrine, zera, murume kana mukadzi, tembiricha, humidity, chikafu, kutenderera kwemuviri, nzira dzekuchenesa ganda, nezvimwe.
Meicet ganda analyzerinogona kushandiswa kuona sebum membrane ine hutano kana kwete. Kana iyo sebum membrane yakanyanya kuonda, ipapo ganda richava rakanyanya kunzwisiswa nekunze kwekunze. Mufananidzo uchapfurwa pasi pemuchinjiko-polarized mwenje uye zvichibva pamufananidzo uyuMeicetsisitimu inoshandisa algorithm kuwana 3 mifananidzo- kunzwa, nzvimbo tsvuku, heatmap. Iyi mifananidzo mitatu inogona kushandiswa kuongorora matambudziko ane ganda.
