Lub teeb nyob rau hauv qhov kawg liab thiab ze-infrared ntawm lub spectrum ua kom sai dua kev kho mob hauv txhua lub hlwb thiab cov nqaij. Ib txoj hauv kev uas lawv ua tiav qhov no yog los ntawm kev ua haujlwm ua cov tshuaj antioxidants muaj zog. Lawv kuj tseem tiv thaiv kev tsim nitric oxide.
Lub teeb liab thiab ze-infrared puas tuaj yeem tiv thaiv lossis thim rov qab qhov kev hnov lus tsis zoo?
Xyoo 2016, cov kws tshawb fawb tau siv lub teeb ci ze-infrared rau cov hlwb pob ntseg hauv vitro ua ntej muab lawv tso rau hauv kev ntxhov siab oxidative los ntawm kev ua rau lawv raug ntau yam tshuaj lom. Tom qab ua rau cov hlwb uas tau kho ua ntej raug tshuaj lom chemotherapy thiab endotoxin, cov kws tshawb fawb tau pom tias lub teeb hloov pauv mitochondrial metabolism thiab kev ntxhov siab oxidative rau txog li 24 teev tom qab kev kho mob.
"Peb tshaj tawm txog kev txo qis ntawm cov cytokines inflammatory thiab cov theem kev ntxhov siab uas tshwm sim los ntawm NIR siv rau HEI-OC1 auditory cell ua ntej kho nrog gentamicin lossis lipopolysaccharide," cov kws sau ntawv tshawb fawb tau sau.
Cov txiaj ntsig ntawm txoj kev tshawb fawb qhia tau hais tias kev kho mob ua ntej nrog lub teeb ze-infrared txo cov cim qhia txog kev o uas cuam tshuam nrog kev nce ntxiv ntawm cov tshuaj reactive oxygen thiab nitric oxide.
Kev Kawm #1: Lub Teeb Liab puas tuaj yeem kho qhov tsis hnov lus zoo?
Cov teebmeem ntawm lub teeb ze-infrared rau kev hnov lus tsis zoo tom qab kev lom tshuaj chemotherapy tau raug soj ntsuam. Kev hnov lus tau raug soj ntsuam tom qab kev siv gentamicin thiab dua tom qab 10 hnub ntawm kev kho lub teeb.
Hauv cov duab scanning electron microscopic, "LLLT ua rau cov plaub hau ntau ntxiv hauv nruab nrab thiab basal tig. Kev hnov lus tau zoo dua los ntawm laser irradiation. Tom qab LLLT kev kho mob, ob qho tib si qhov kev hnov lus thiab cov plaub hau-cell suav tau zoo dua. "
Kev Kawm #2: Lub Teeb Liab puas tuaj yeem kho qhov tsis hnov lus zoo?
Hauv kev tshawb fawb no, cov nas tau raug suab nrov heev hauv ob lub pob ntseg. Tom qab ntawd, lawv lub pob ntseg sab xis tau raug tshuaj tua kab mob ze-infrared rau 30 feeb txhua hnub rau 5 hnub.
Kev ntsuas ntawm lub hlwb pob ntseg teb tau qhia txog kev rov zoo sai ntawm kev ua haujlwm pob ntseg hauv cov pab pawg kho nrog LLLT piv rau pawg tsis kho mob ntawm hnub 2, 4, 7 thiab 14 tom qab raug suab nrov. Kev soj ntsuam morphological kuj qhia txog tus nqi ciaj sia ntawm cov plaub hau sab nraud siab dua hauv cov pab pawg LLLT.
Thaum nrhiav cov cim qhia txog kev ntxhov siab oxidative thiab apoptosis hauv cov hlwb tsis kho vs kho, cov kws tshawb nrhiav pom tias "muaj zog tiv thaiv kab mob tau pom nyob rau hauv cov ntaub so ntswg sab hauv ntawm pawg tsis kho, thaum cov cim no tau txo qis hauv pawg LLLT ntawm 165mW / cm (2) lub zog ceev."
"Peb cov kev tshawb pom qhia tias LLLT muaj cov teebmeem cytoprotective tawm tsam NIHL los ntawm kev txwv tsis pub iNOS qhia tawm thiab apoptosis."
Kev Kawm #3: Lub Teeb Liab puas tuaj yeem kho qhov tsis hnov lus zoo?
Xyoo 2012, muaj cuaj tus nas raug suab nrov nrov thiab tau sim siv lub teeb ze infrared los kho pob ntseg. Ib hnub tom qab raug suab nrov nrov, cov nas pob ntseg sab laug tau kho nrog lub teeb ze infrared rau 60 feeb rau 12 hnub sib law liag. Cov pob ntseg sab xis tsis tau kho thiab suav tias yog pawg tswj.
"Tom qab kev siv hluav taws xob thib 12, qhov kev hnov lus qis dua rau pob ntseg sab laug piv rau pob ntseg sab xis." Thaum saib siv lub tshuab hluav taws xob microscope, tus lej ntawm cov plaub hau pob ntseg hauv pob ntseg uas tau kho yog ntau dua li ntawm pob ntseg uas tsis tau kho.
"Peb cov kev tshawb pom qhia tias kev siv laser irradiation qis qis txhawb kev rov qab zoo ntawm cov qhov hnov lus tom qab raug mob hnyav."
