Piv txwv li, kev kawm nyhav kuj yog ib hom kev nyuab siab. Cov kws kho mob yuav paub tseeb tias lawv ua rau micro-ruptures nyob rau hauv cov nqaij fibers ... thiab qhov kev kho ntawm cov lesions ua ib tug stimulus rau txoj kev loj hlob thiab kev loj hlob ntawm cov leeg. Thawj qhov kev pom zoo hais tias kev nyuaj siab me me tau muaj txiaj ntsim ntawm cov kab mob nyob ntawm tus kws kho mob German Hugo Schulz thaum xaus ntawm lub xyoo pua puv 19. Nws pom tias cov poov xab haj ntau zog yog tias lawv ntxiv microdoses ntawm cov tshuaj lom. Qhov tshwm sim tom qab ntawd hu ua "hormone", los ntawm cov lus Greek "kev zoo siab, kev mob siab". Nws tshwm sim hauv nws tus kheej thaum muaj sia muaj kab mob tsawg tsawg ntawm cov hluav taws xob, tshuaj lom, kub thiab lwm yam teeb meem. Thaum cov tshuaj no tsis txaus ua rau lawv tsis tuaj yeem ua rau muaj kev puas tsuaj, peb pom daim duab rov qab: kho lub cev kom txhob muaj kev puas tsuaj me me, lub cev ua haujlwm sab hauv thiab tsis yog rov qab kho qhov kev puas tsuaj xwb, tiam sis kho qhov mob ntawm cov ntaub so ntswg. Kom paub meej, saib tsab xov xwm "Cov nyhuv ntawm kev pw tsaug zog thiab kev nyuab siab ntawm kev noj qab haus huv".
Microdose siv
Ib tug neeg biogerontologist Suresh Rattan los ntawm University of Aarhus (Denmark) npaj siab siv cov tshuaj hormone los tua cov hnub nyoog txog kev hloov. Nws ua tim khawv tias niaj zaus raug micro-koob tshuaj ntawm txoj kev ntxhov siab txhawb txoj kev tiv thaiv ntawm cov hlwb thiab txo qis txoj kev laus. Cov kev nyuab siab no tuaj yeem ua rau lub cev muaj teeb meem (kev kub hnyiab, UV hluav taws xob, kev sib tw ua si), noj zaub mov tsis zoo (noj tsis muaj calorie ntau ntau, qee yam khoom noj khoom haus, ua qhwv thiab lwm tus), mob hlwb (piv txwv, kev zoo siab ua ntej ua pej xeem). Nyob rau hauv 2002, Rattan thiab nws cov npoj yaig kawm tshawb fawb ntawm cov koob tshuaj me me ntawm kev ntxhov siab ntawm cov kua nplaum hauv cov laus hauv cov pob txha fibroblasts (hlwb lub luag hauj lwm rau kev tsim cov roj hmab thiab elastin). Cov kws tshawb fawb tau nyiam nyob hauv ib lub npe hu ua heat shock proteins (HSP70), uas muaj kev koom tes hauv lub cev cov lus teb rau kev ntxhov siab. Tom qab lub cev kub hnyav, qhov theem ntawm cov protein no nyob rau hauv lub hlwb ntau dua, thiab nrog nws - tsis kam mus ultraviolet thiab ib co tshuaj lom. Cov laus zuj zus tuaj yeem ua haujlwm ntau thiab muaj zog.
Cov tshuaj txhaj tiv thaiv kev laus
Tshaj tawm los ntawm qhov kev tshawb nrhiav, cov kws tshawb fawb ntawm cov chaw soj ntsuam tau sib koom nrog ib pawg kws tshawb fawb los ntawm Rattan thiab tsim ib qho kev tiv thaiv kab mob uas muaj zog ntawm cov khoom xyaw, uas ua rau cov tshuaj hormones, cov tshuaj hormone. Nyob rau hauv cov ntaub ntawv no, lawv tuaj yeem tsim cov khoom noj khoom haus no thiab ua li no rau hauv cov txheej txheem kev laus. Lub complex muaj xws li extract ntawm ginseng Sanchi thiab gipotaurin, uas yog tau los ntawm taurine - ib qho ntawm cov amino acids tam sim no nyob rau hauv tib neeg lub cev.
Nyhuv
Nyob rau hauv lub chav kawm ntawm cov kev tshawb fawb, nws tau pom hais tias, 6 teev tom qab daim ntawv thov ntawm ntshav dej, qhov ntau lawm ntawm HSP70 protein nyob hauv hlwb tau nce 24%. Cov kev soj ntsuam kuaj pom tau hais tias tawv nqaij tsis haum rau sab nraud influences tom qab lub hlis uas siv cov kev mob ntses nce li 3%. Xwb, cov microstresses ua ib qho kev sib txuas ntawm 3 cov lus teb biochemical kev sib tsoo ntawm lub cev thiab qhib cov kub cev nqaij tawv. Cov hormone tsis tsuas pab hlwb tiv thaiv kev laus, tab sis kuj nce lub sijhawm ntawm lub neej hauv lub cev ntawm lub zog. Feem ntau cov European dermatologists thiab cosmetologists pom zoo tias kev siv cov khoom tu tawv nqaij los ntawm kev nkag siab tob txog tib neeg lub cev nqaij daim tawv thiab biochemistry rau kev nkag siab txog cov khoom txav ntawm cov nqaij ntshiv muaj peev xwm coj tau zoo. Qhov loj tshaj plaws yog los xyuas kom meej meej lawv siv. Tam sim no peb paub dab tsi ntawm kev pw tsaug zog thiab kev ntxhov siab ntawm kev noj qab haus huv ntawm daim tawv nqaij.
