Tohutohu Tiaki Kiri——Ngā Take e Pā Ana ki te Āhua o te Kiri

Ko te nuinga o te wā ka hangaia te elastin tangata mai i te mutunga o te kukunetanga ki te tīmatanga o te whānautanga, ā, tata kore rawa he elastin hou e puta i te wā pakeketanga. He rerekē ngā huringa o ngā muka rapa i te wā o te koroheketanga taketake me te photoaging.

1. Te ira tangata me ngā wāhanga tinana rerekē

I te tau 1990 anō, i whakamatautauria e ētahi tohunga ngā tūao e 33 ki te ako i te ngāwari o te kiri i ngā wāhanga 11 o te tinana tangata.

E tohu ana he tino rerekē te ngāwari o te kiri i waenga i ngā wāhanga rerekē; ahakoa kāore he rerekētanga nui i waenga i ngā ira tangata rerekē

Ka heke haere te ngāwari o te kiri i te kaumātuatanga.

2. Tau

I te pakeketanga, ka iti ake te ngāwari me te ngāwari o te kiri tawhito taketake i te kiri taitamariki, ā, ka pakaru, ka heke te whatunga muka ngawari, ka puta ko te papatahi o te kiri me ngā kita angiangi; i roto i te koroheketanga taketake, ehara i te mea ko te pirau muka o ngā wāhanga ECM anake, engari ko te ngaronga o ētahi maramara oligosaccharide. I piki ake te whakahaere o LTBP-2, LTBP-3, me LOXL-1, ā, he mahi nui tā LTBP-2 me LOXL-1 ki te whakahaere me te pupuri i te whakatakotoranga, te huihuinga, me te hanganga o te fibrin mā te here i te fibulin-5. Ko ngā raruraru e pā ana ki te whakaaturanga o ngā āhuatanga ka puta hei tikanga hei whakanui ake i te koroheketanga taketake.

3. Ngā āhuatanga taiao

Kua āta tirohia haeretia ngā kino o te kiri nā ngā āhuatanga taiao, arā, te koroheketanga o te kiri, te parahanga o te hau me ētahi atu āhuatanga, engari kāore ngā hua o te rangahau i te tino whai kiko.

Ko te kiri kua pakeke haere te kiri e tohuhia ana e te hanga me te whakawhiti i ngā āhuatanga e rua, arā, te catabolic me te anabolic. He āhua taratara, he hohonu hoki te miro o te kiri, ehara i te mea nā te ngaronga o ngā microfibrils whai kiko-fibrillin i te hononga o te epidermis-dermal, te pirau o te elastin, engari ko te mea nui ake, nā te whakatakotoranga o ngā matū elastin pōrearea ki roto i te dermis hohonu, ka pāngia te mahi a te elastin.

Kāore e taea te whakatika i te kino o te hanganga o ngā muka pīwariwari o te kiri i mua i te 18 tau te pakeke, ā, he mea nui te tiaki UV i te wā tipu. E rua pea ngā tikanga o te hihi o te rā o ngā muka pīwariwari: ka pakaru ngā muka pīwariwari e te elastase e tukuna ana e ngā pūtau e karapoti ana, ka whitia rānei e te UV, ā, ka piko ngā muka pīwariwari i te wā o te tukanga hanga; he pānga tō ngā pūtau pūtau ki te whakatairanga i ngā muka pīwariwari kia mau tonu te rārangi. Ka ngoikore haere te pānga, ka hua ake te piko.—— Yinmou Dong Te Pāpāho Ahumahi Matū, 158-160

Kāore pea te tukanga whakarerekētanga o te ngāwari o te kiri e kitea whānuitia ana e te kanohi tahanga, ā, ka taea e tātou te whakamahi i te tohunga ngaiotātaritanga kirite tirotiro me te matapae i te ia o ngā huringa o te kiri ā muri ake nei.

Hei tauira,ISEMECO or Kaitātari Kiri Resur, mā te āwhina o te rama ngaio me te kāmera whakamārama-teitei hei pānui i ngā mōhiohio kiri, me te whakakotahitanga o te rauropi tātaritanga AI, ka taea te tirotiro i ngā taipitopito me te matapae i ngā huringa kiri.
