Ngokuvamile, lapho abakhiqizi be-OEM bezimonyo bethuthukisa imikhiqizo yokulwa nokuguga, ukuze bafeze imiphumela ephelele yokulwa nokuguga, bavame ukuklama amafomula omkhiqizo ngokusekelwe emibonweni emine eyisisekelo yokulwa nokuguga kwamaseli ethuthukiswe ososayensi. Lona umqondo oyisisekelo wokulwa nokuguga kwamaseli. Ake silandele Ake sithole ndawonye.
Ithiyori ye-DNA ye-genotypic cell aging theory, ngoba i-DNA yomuntu inamandla okuphindaphinda nokukhula njalo, ngakho-ke amaseli ane-metabolism eqhubekayo. Uma ukuphindaphindwa kwe-DNA kufinyelela ekugcineni futhi kungakwazi ukuqhubeka nokuphindaphindwa, ikhono lokuzilungisa le-DNA lizoba libi kakhulu, futhi abantu bazoba ngabagugile ngokwemvelo. Ngenxa yalesi sizathu,imikhiqizo ye-OEM yezimonyokwazalwa izakhi zofuzo zokulungisa ezahlukene.
Umbono Wokusetshenziswa Kwamaseli Uma amangqamuzana esaphila, azoqhuba ukusabela okuhlukahlukene kwamakhemikhali futhi akhiqize imijikelezo ye-oxidative. Ngesikhathi esifanayo, akhiqiza futhi imfucuza ye-metabolic, evimbela amakhono amangqamuzana futhi ithinte ukusebenza kwe-metabolism okuvamile. Ngenxa yalokho, abantu bathambekele ekugugeni.
Ithiyori yama-free radical: Lapho amangqamuzana egaywa, akhiqiza i-hydrogen peroxide, ebolisa inani elincane lama-hydroxyl radicals. Ukushiswa kwemisebe yezinhlobo ezahlukene zokukhanya njengemisebe ye-ultraviolet kuzophinde kubangele isikhumba ukuthi sakhe ama-free radicals. Isibonelo, izinto ezifana ne-SOD ezivela kuma-OEM ezimonyo zisetshenziselwa ngokukhethekile ukubhekana nama-free radicals. Ngenxa yokuthi ukukhanya kukhiqiza kalula ama-free radicals, ukuvikelwa kwelanga kubalulekile ekulweni nokuguga.
Ithiyori yokuphelelwa amanzi emzimbeni kwamangqamuzana: Ukuphelelwa amanzi emzimbeni kwamangqamuzana kwenza izinto ezisemaselini zome futhi zilahlekelwe amandla azo okukhula, okubangela ukuba amangqamuzana aguge. Izimboni ze-OEM zezimonyo zinezindlela eziningi zokuthambisa nokugcina amanzi emzimbeni kwamangqamuzana, ezazalelwa le njongo.
Kuphela ngokwelashwa okufika ngesikhathi nangokuphumelelayo kwamangqamuzana alimele namaseli asebekhulile, ukuze amangqamuzana alimele alulame futhi amangqamuzana asebekhulile asebenze, izicubu zezitho kanye nemisebenzi yomzimba ingabuyiselwa ngokuphelele esimweni esijwayelekile, futhi umzimba womuntu ungahlala uphilile futhi usemncane ngempela. Ngakho-ke, ukubaluleka okusebenzayo komqondo wokulwa nokuguga kwamangqamuzana ukusebenzisa imikhiqizo yokulungisa i-DNA kanye nemikhiqizo ye-SOD ukuqinisa ukuvikelwa kwelanga, ukwenza mhlophe kanye nokuthambisa.
