Umphumela wokuvikela weIsikhumba se-microcologyesikhunjeni
Izindlala ze-Sebaceous zifihla ama-lipids, ahlanjululwe ama-microorganisms ukwakha ifilimu ekhuphukile ye-lipid. Lawa mafilimu e-lipid aqukethe ama-acid ama-fatty acid, abizwa nangokuthi amafilimu e-acid, angaphazamisa izinto ze-alkaline ezingcoliswe esikhunjeni futhi zivimbela amagciwane aphesheya (adlulise amagciwane). , isikhunta namanye ama-microgenic microoorganisms akhula, ngakho-ke umsebenzi wokuqala we-skin flora ejwayelekile ngumphumela obalulekile wokuvikela.
Ukuhlaselwa kwesikhumba kanye nezinsizi, kufaka phakathi izindlala zezithukuthuku (izindlala zezithukuthuku), izindlala ze-sebaceous, nama-follicle wezinwele, zinezimbali zazo ezihlukile. Izindlala ze-Sebaceous zixhuma ama-follicle wezinwele ukuze wakhe iyunithi ye-sebaceous e-follicular, ekhombisa into ecebile ye-lipid ebizwa ngeSebum. I-Sebum iyifilimu evikela i-hydrophobic evikela futhi ethambisa isikhumba nezinwele futhi isebenza njengesihlangu se-antibacterial. Izindlala ze-sebaceous zikhulu nge-hypoxic, zisekela ukukhula kwamagciwane anaerobic aphambili afanaP. Acnes, equkethe uP. I-Likase ye-ACNES EDLULA I-SEBUM, Hydrolyzes Triglycerelides eSebum, futhi ikhipha ama-fatty acids wamahhala. Amagciwane anganamathela kulezi zinamafutha zamahhala, ezisiza ukuchaza ikholoni le-sebaceous gland nguP. Acids futhi la ma-acid ama-Fatty Acid nawo anikela nge-acidity yendawo yesikhumba (PHS 5). Amagciwane amaningi ajwayelekile e-pathogenic, njenge-staphylococcus aureus kanye ne-streptococcus pyogenes, avinjelwe endaweni ene-acid futhi ngenxa yalokho athande ukukhula kwe-staphylococci engemihle namagciwane e-coryform. Kodwa-ke, ukugqugquzelwa kwesikhumba kuphumela ekukhuphukeni kwe-PH okuzokwenza ukukhula kuka-S. Aureus naseS. Pyogene. Ngoba abantu bakhiqiza ama-sebum triglycerides amaningi kunezinye izilwane, ngaphezulu uP. Acnes Colonize isikhumba somuntu.
