Te Pānga Tiaki oTe Irahiko Kirii runga i te kiri
Ka whakaputahia e ngā repe hinu ngā lipid, ka whakapūpūtia e ngā moroiti hei hanga i tētahi kiriata lipid kua whakapūpūtia. Kei roto i ēnei kiriata lipid ngā waikawa ngako kore utu, e mōhiotia ana ko ngā kiriata waikawa, ka taea te whakakore i ngā matū kawakore kua poke i te kiri, ā, ka ārai i ngā huakita ke (ngā huakita e haere ana). , ka tipu ngā harore me ētahi atu moroiti mate, nō reira ko te mahi tuatahi o ngā tipu kiri noa he pānga tiaki nui.
He momo tipu motuhake kei roto i ngā whatukuhu o te kiri me ngā awhi, tae atu ki ngā repe werawera (ngā repe werawera), ngā repe hinu, me ngā pūtake makawe. Ka hono ngā repe hinu i ngā pūtake makawe hei hanga i te wāhanga hinu follicular, e whakaputa ana i tētahi matū momona e kiia nei ko te sebum. He kiriata tiaki hydrophobic te sebum e tiaki ana, e whakahinuhinu ana i te kiri me te makawe, ā, he ārai huakita hoki. He iti te hau o ngā repe hinu, e tautoko ana i te tipu o ngā huakita anaerobic facultative pērā i teP. acnes, kei roto ko te lipase P. acnes e whakaiti ana i te hinu, e whakawhaiti ana i ngā triglycerides i roto i te hinu, ā, e tuku ana i ngā waikawa ngako kore utu. Ka taea e ngā huakita te piri ki ēnei waikawa ngako kore utu, e āwhina ana ki te whakamārama i te noho o ngā repe hinu e te P. acnes, ā, ka whai wāhi atu hoki ēnei waikawa ngako kore utu ki te waikawa o te mata kiri (pH o te 5). He maha ngā huakita mate noa, pērā i te Staphylococcus aureus me te Streptococcus pyogenes, ka āraihia i roto i te taiao waikawa, nō reira he pai mō te tipu o ngā staphylococci coagulase-negative me ngā huakita coryneform. Heoi, ko te aukati i te kiri ka hua ake te pikinga o te pH ka pai ake te tipu o te S. aureus me te S. pyogenes. Nā te mea he nui ake ngā triglycerides sebum e whakaputaina ana e te tangata i ētahi atu kararehe, he nui ake ngā P. acnes e noho ana i te kiri tangata.
