Iziphumo zokukhuselaI-microcology yolusukulusu

I-Sebaceous Gipids ye-SebaceTe, ezithenjisiweyo zii-microorganisms ukwenza ifimidi ye-wipid ekhutshiwe. Ezi filim ze-lipid zinee-Acids zasimahla, ezikwabizwa ngokuba ziifilimu ze-ACID, ezinokuthi zingathinteli izinto ze-alkaline zingcolise ulusu kwaye zithintele intsholongwane ye-bacteria). , fungi kunye nezinye ii-microorganisms ezincinci zePathogenic zikhula, ke umsebenzi wokuqala we-flora yesikhumba esiqhelekileyo sisiphumo esibalulekileyo sokukhusela.

Ukuvalwa kolusu kunye nokuhlonishwa, kubandakanya i-cynds glats (i-sweat grends), amadlala e-sebaceous, kunye neefolliles zeenwele, zinezityalo zabo ezahlukeneyo. I-sebaceous gland ixhuma iifollicles zeenwele zokwenza iyunithi ye-follicoural sebaceous, efihlela into ebizwa ngokuba yiSebum. I-sebum yifilimu yokukhusela i-hydrophobic ekhusela kwaye ikhulisa ulusu kunye neenwele kwaye isebenze njengekhali le-antibacteria. I-sebaceous grands i-hypoity, ixhasa ukukhula kwe-bacteriac ye-anaeltic aneaerobic anjeP. iiacnes, equlethe i-p. Acnes liipse of i-derade sebum, i-hydrolyzes triglycerides kwi-sebum, kwaye ikhuphe i-acids mafutha Acids. Intsholongwane inokubambelela kula macids yasimahla, encedisa ukuchaza ikoloni ye-sebaceous ggrads yi-P. Acnes, kwaye ezi zifakiweyo zinegalelo kwi-acidity ephezulu (ph ye-5). Iintsholongwane ezininzi eziqhelekileyo ze-pathogenic, ezinjenge-staphylococcus Aures kunye ne-Preptococcus Pyogenes, zithintelwe kwindawo ye-acidic kwaye ke ziyathandeka ekukhuleni kwe-staphylococci ye-staphysi kunye ne-coryneforma. Nangona kunjalo, ukubakho kolusu kuphumela kuphuhliso kwi-PH kuya kuya kukhangela ukukhula kwe-S. Aures kunye ne-Pyogenus. Kuba abantu bavelisa i-sebum engaphezulu kweShum triglycerides kunezinye izilwanyana, ii-P
