Elastin yemunhu inonyanya kugadzirwa kubva panguva yekupedzisira kwemwana ari mudumbu kusvika pakutanga kwekuzvarwa, uye hapana elastin itsva inogadzirwa panguva yekukura. Fiber dze elastic dzinoshanduka zvakasiyana panguva yekukwegura kwemwana uye fotoaging.
1. Murume kana Mukadzi uye nhengo dzakasiyana dzemuviri
Kare muna 1990, dzimwe nyanzvi dzakaedza vanhu 33 vaizvipira kuti vadzidze kusimba kweganda muzvikamu 11 zvemuviri wemunhu.
Zvinoratidza kuti ganda rinopfava zvakasiyana zvikuru pakati pezvikamu zvakasiyana; nepo pasina musiyano wakakosha pakati pevanhurume nevanhukadzi vakasiyana.
Kusimba kweganda kunoderera zvishoma nezvishoma nekukura.
2. Zera
Nekukura kuri kuramba kuchiwedzera, ganda rekare rinokura zvishoma uye harina kupfava kupfuura ganda diki, uye network ye elastic fiber inotyoka uye inodzikira, zvichionekwa seganda richipfava uye makwinya matete; mukukwegura kwekare, kwete chete Kuora kwe fibrous kwezvikamu zveECM, asiwo kurasikirwa kwezvimwe zvikamu zve oligosaccharide. LTBP-2, LTBP-3, uye LOXL-1 zvese zvakavandudzwa, uye LTBP-2 neLOXL-1 zvinoita basa rakakosha mukudzora nekuchengetedza fibrin deposition, kuunganidza, uye chimiro kuburikidza nekubatanidza fibulin-5. Kuvhiringidzika kunobatanidzwa ne factor expression kunobuda senzira dzekuwedzera kukwegura kwekare.
3. Zvinhu zvakatipoteredza
Kukuvadzwa kwezvinhu zvakatipoteredza paganda, kunyanya kutorwa kwemifananidzo, kusvibiswa kwemhepo nezvimwe zvinhu kwave kutariswa zvishoma nezvishoma, asi mhedzisiro yekutsvagisa haina kurongeka.
Ganda rinokura rinoratidzwa nekuchinja kweganda uye kuchinja kweganda. Ganda rinoita serakaomarara uye rakakombama zvakanyanya nekuda kwekurasikirwa kwe microfibrils dzakapfuma mu fibrillin panosangana epidermis nedermal, kuora kwe elastin, asi chinonyanya kukosha, kuiswa kwezvinhu zvisina kunaka mu deep dermis, basa re elastin richikanganiswa.
Kukuvadzwa kweganda ne elastic fibers hakugadzirisiki vasati vasvitsa makore gumi nemasere, uye dziviriro ye UV inokosha panguva yekukura. Panogona kunge paine nzira mbiri dzezuva re elastic fiber: elastic fibers dzinokanganiswa ne elastase inoburitswa nemasero akakomberedza kana kupiswa ne UV, uye elastic fibers dzinokombama panguva yekugadzira; fibroblasts dzine simba rekusimudzira elastic fibers kuti dzirambe dzakatwasuka. Mhedzisiro yacho inova isina simba, zvichikonzera kukotama.—— Yinmou Dong
Kuchinja kweganda kuti rive nyore kusimba kunogona kusanyatsooneka nemaziso, uye tinogona kushandisa nyanzvi.muchina wekuongorora gandacherechedza uye fungidzira mafambiro ekuchinja kweganda mune ramangwana.
Semuyenzaniso,ISEMECO or Resur Ganda Analyzer, nerubatsiro rwemwenje wehunyanzvi uye kamera yepamusoro-soro yekuverenga ruzivo rweganda, pamwe chete neAI analysis algorithm, vanogona kuona ruzivo nekufanotaura kwekuchinja kweganda.
