Tib neeg Elastin yog feem ntau ua tau los ntawm kev lig embryonic mus rau lub sij hawm tam sim no neonatal, thiab yuav luag tsis muaj elastin thaum ntxov tshiab yog tsim thaum laus. Elastic fibers yauv hloov pauv sib txawv thaum lub sij hawm endogenous laus thiab kev ua ntaub ntawv.
1. Tub los ntxhais thiab lub cev sib txawv
Thaum ntxov li xyoo 1990, qee cov kws tshawb fawb xeem 33 tuaj pab dawb los kawm cov tawv nqaij elasticity ntawm 11 seem ntawm tib neeg lub cev.
Qhia tias cov tawv nqaij elasticity yog qhov sib txawv ntawm ntau qhov chaw; Thaum muaj qhov tsis muaj qhov sib txawv ntawm cov tub ntxhais sib txawv
Daim tawv Elasticity maj mam txo raws li lub hnub nyoog.
2. Lub hnub nyoog
Nrog ua kom cov laus ua kom tiav, cov tawv nqaij thaum muaj kev laus qis dua thiab muaj peev xwm dua li cov tawv nqaij uas yau, thiab tsis tshua muaj cov tawv nqaij uas tsis tau zoo, thiab cov tawv nqaij ua kom zoo nkauj thiab tawv nqaij; Nyob rau hauv endogenous laus, tsis tsuas yog fibrous degradation ntawm ECM Cheebtsam, tab sis kuj yog ploj ntawm qee cov oligosaccharide. LTBP-2, LTBP-3, thiab LEXL-1 tau tag nrho cov kev tswj hwm, thiab khaws cia Fibrin Deposition, sib dhos, thiab qauv los ntawm BRING FIBULIN-5. Kev tso cai cuam tshuam nrog cov kev qhia tawm yog cov tshuab ua kom nce qib endogenous laus.
3. Ib puag ncig cov khoom siv
Qhov kev puas tsuaj ntawm cov tawv nqaij, tsuas yog ua kom tawv nqaij, huab cua ua qias tuaj thiab lwm yam tau them maj mam ua raws li, tab sis cov kev tshawb fawb tsis yog.
Cov tawv nqaij photicaging yog tus cwj pwm los ntawm kev hloov kho catabolic thiab anabolic ripodeling thiab kev hloov pauv. Daim tawv nqaij zoo li ntxhib thiab tob tob vim tsis tsuas yog rau kev poob ntawm cov kev sib tw ntawm cov neeg muaj kev sib tw, rau kev tso nyiaj ntau ntxiv rau hauv kev sib sib zog nqus dermis, txoj haujlwm ntawm Elastin cuam tshuam.
Cov txheej txheem kev puas tsuaj rau cov tawv nqaij elastic ntawm daim tawv nqaij yog txawv ua ntej hnub nyoog 18, thiab UV kev tiv thaiv yog qhov tseem ceeb thaum lub sijhawm kev loj hlob. Tej zaum yuav muaj ob lub tshuab ntawm elastic fiber ntau lub hnub ci: elastic fibers yog degringase los ntawm UV, thiab elastic fibers yog bibers yog bibers yog bated thaum lub sij hawm hluavtaws; Fibroblasts muaj cov txiaj ntsig ntawm kev txhawb nqa elastic fibers kom muaj kev tswj hwm. Cov nyhuv ua tsis muaj zog, ua rau khoov .-- Yinmou Dong
Cov txheej txheem hloov ntawm daim tawv nqaij elasticity tej zaum yuav tsis pom tseeb txaus rau lub qhov muag liab qab, thiab peb tuaj yeem siv tus kws tshaj lijDaim hlab daim ntawv kuaj xyuas ntsuasSaib thiab txawm kwv yees kev hloov pauv yav tom ntej ntawm daim tawv nqaij.
Piv txwv li,Isemeco or Rov pib muag daim tawv analyzer, nrog kev pab ntawm kev teeb pom kev zoo thiab cov koob yees duab siab txhais tau cov duab no, ua ke nrog cov ntsiab lus ntawm cov tawv nqaij, ua ke nrog cov ntsiab lus thiab twv ua ntej ntawm daim tawv nqaij hloov.
