Kev tshawb fawb txog kev tshawb fawb:
1. Kev tshawb fawb ntawm tes:
Photopigmentation tuaj yeem siv los ua cov cuab yeej tseem ceeb hauv kev tshawb fawb ntawm tes. Tshwj xeeb, nws tuaj yeem siv los tshawb nrhiav cov txheej txheem cuam tshuam rau kev loj hlob ntawm tes, apoptosis thiab lwm yam xov tooj ntawm tes taw qhia txoj hauv kev. Cov kev tshawb fawb tau pom tias photochromes tuaj yeem cuam tshuam qhov kev loj hlob thiab induce apoptosis ntawm tib neeg lub ntsws cancer hlwb los ntawm ap53-dependent mechanism. Qhov kev tshawb pom no yog qhov tseem ceeb rau kev nkag siab tob txog cov txheej txheem ntawm kev txhim kho mob qog noj ntshav thiab tshawb nrhiav cov tshuaj tiv thaiv kab mob uas muaj peev xwm, uas muab cov lus qhia tshiab thiab cov tswv yim rau kev tshawb fawb txog qog noj ntshav.
2. Kev tshawb fawb biochemical:
Hauv kev ua haujlwm ntawm biochemistry, photochromes tuaj yeem siv los kawm txog cov haujlwm enzyme thiab cov txheej txheem ntawm kev ua haujlwm. Tej zaum yuav muaj kev cuam tshuam ntawm photopigments thiab qee cov enzymes, uas cuam tshuam rau kev ua haujlwm enzyme. Kev tshawb fawb tob tob ntawm cov kev sib cuam tshuam no tuaj yeem pab qhia txog kev ua haujlwm ntawm cov enzymes thiab cov txheej txheem metabolic hauv cov kab mob, muab cov ntsiab lus nkag tshiab rau kev tshawb fawb biochemical.
3, Kev tshawb fawb Photochemical:
Photopigments yog photodegradation khoom ntawm riboflavin (vitamin B2). Kev kawm txog nws cov khoom siv photochemical tuaj yeem ua rau peb nkag siab tob txog kev sib cuam tshuam ntawm lub teeb thiab teeb meem thiab cov txheej txheem ntawm cov tshuaj tiv thaiv photochemical. Cov txiaj ntsig kev tshawb fawb no muaj cov txiaj ntsig tseem ceeb hauv thaj chaw ntawm photochemistry thiab photobiology, thiab muab cov lus qhia tshiab thiab cov txheej txheem rau kev tshawb fawb hauv cov haujlwm muaj feem xyuam.
Cov yam ntxwv ntawm daim ntawv thov kev kho mob muaj peev xwm:
1, Muaj peev xwm lub hom phiaj rau kev txhim kho tshuaj:
Tam sim no, photopigments raws li lub hom phiaj rau kev txhim kho tshuaj tseem nyob rau theem tshawb fawb. Txawm li cas los xij, nws cov khoom tshwj xeeb lom neeg ua rau nws muaj peev xwm ua lub hom phiaj rau kev tsim tshuaj. Nyob rau hauv lub neej yav tom ntej, los ntawm kev tshawb fawb tob ntawm cov txheej txheem ntawm kev ua ntawm photochromes, nws xav tias yuav tsim cov tshuaj tshiab rau cov kab mob uas cuam tshuam thiab coj cov kev hloov tshiab hauv kev kho mob.
2.Auxiliary diagnosis:
Hauv kev kuaj mob, qhov pom ntawm photopigments lossis kev hloov pauv hauv lawv qib yuav cuam tshuam nrog qee yam kab mob. Kev tshawb nrhiav thiab kev tshuaj xyuas ntawm photopigment tuaj yeem muab cov ntaub ntawv pabcuam rau kev kuaj mob ntawm qee yam kabmob. Txawm li cas los xij, kev tshawb fawb tam sim no hauv cheeb tsam no tsis sib sib zog nqus txaus, thiab cov kev tshawb fawb txuas ntxiv yog xav tau los txiav txim siab tus nqi thiab daim ntawv thov kev cia siab ntawm photopigment hauv kev kuaj mob.
Lwm qhov chaw::
Hauv kev tshuaj ntsuam xyuas tshuaj thiab tshuaj tshuaj, photopigment tuaj yeem siv los ua tus qauv lossis kev tswj hwm. Nws tuaj yeem siv rau kev tsim thiab kev lees paub ntawm cov txheej txheem kev soj ntsuam, nrog rau kev soj ntsuam zoo thiab ntau yam ntawm lwm cov tebchaw. Daim ntawv thov no muab cov cuab yeej tshiab thiab cov txheej txheem rau kev tshuaj xyuas tshuaj thiab tshuaj tshuaj, thiab pab txhim kho qhov tseeb thiab kev ntseeg siab ntawm kev tshuaj xyuas.
