UVB lub teeb nws tus kheej tsis tuaj yeem kho cov calcium uas tsis muaj peev xwm ncaj qha, tab sis los ntawm kev txhawb nqa cov synthesis ntawm vitamin D hauv daim tawv nqaij, nws tuaj yeem pab txhim kho calcium nqus thiab metabolism, yog li ua lub luag haujlwm pabcuam hauv calcium deficiency -cov kab mob ntsig txog (xws li osteoporosis thiab rickets). Cov hauv qab no yog ib qho kev ntsuam xyuas tshwj xeeb:
1. Kev sib raug zoo ntawmUVB teebthiab calcium metabolism
Synthesis ntawm vitamin D
Thaum UVB (wavelength 290-315nm) irradiates ntawm daim tawv nqaij, nws muaj peev xwm hloov 7-dehydrocholesterol nyob rau hauv lub epidermis rau vitamin D3 (cholecalciferol), uas yog lub ntsiab qhov chaw ntawm 80% ntawm vitamin D nyob rau hauv tib neeg lub cev.
Tom qab vitamin D tau qhib los ntawm lub siab thiab lub raum, nws txhawb txoj hnyuv nqus calcium thiab phosphorus thiab tswj cov ntshav calcium concentration.
Feem ntau ua rau tsis muaj calcium
Vitamin D tsis txaus: ua rau tsis txaus calcium nqus, thiab nws nyuaj rau siv txawm tias calcium ntxiv los ntawm kev noj haus.
Kev noj cov calcium tsis txaus: tsawg dhau ntawm cov khoom noj siv mis thiab cov zaub ntsuab ntsuab hauv cov zaub mov.
Cov kab mob: hypoparathyroidism, mob raum, thiab lwm yam.
2. Muaj xwm txheej ntawmUVB teeb(290-315nm)
Rickets / osteomalacia
Muaj feem xyuam rau rickets rau cov menyuam yaus lossis osteomalacia hauv cov neeg laus los ntawm vitamin D tsis txaus.
Cov lus pom zoo ntawm kev kho mob: nruab nrab hnub raug 2-3 zaug hauv ib lub lis piam (tawm lub ntsej muag thiab caj npab rau 10-30 feeb), lossis ntxiv los ntawm kev kho mob UVB phototherapy.
Osteoporosis hauv cov neeg laus
Lub peev xwm ntawm cov neeg laus cov tawv nqaij los ua kom cov vitamin D txo qis (txog 75%), thiab UVB irradiation tuaj yeem pab nce qib vitamin D thiab txhim kho calcium nqus.
Cov pejxeem tshwj xeeb
Ntev- cov neeg ua haujlwm sab hauv tsev thiab cov neeg nyob hauv siab - thaj chaw latitude (tsis muaj hnub ci) tuaj yeem ntxiv cov vitamin D los ntawm UVB phototherapy.
3. Kev ceev faj thiab kev pheej hmoo
Kev tswj tshuaj noj kom zoo
Kev pheej hmoo ntawm kev raug overexposure: tej zaum yuav ua rau daim tawv nqaij sunburn, photoaging, thiab txawm yuav ua rau muaj kev pheej hmoo ntawm mob cancer ntawm daim tawv nqaij (xws li melanoma).
Cov lus pom zoo: Zam kom tsis txhob raug lub hnub ntev, thiab siv UVB phototherapy raws li tus kws kho mob cov lus qhia los tswj lub sij hawm raug thiab siv.
Cov xwm txheej siv tsis tau
Rau cov neeg uas muaj vitamin D txaus: ntxiv UVB raug tsis muaj txiaj ntsig, thiab kuaj ntshav (25 (OH)D) yuav tsum paub tseeb tias lawv tsis txaus.
Qee yam kab mob ntawm daim tawv nqaij: xws li lupus erythematosus thiab photosensitive dermatitis cov neeg mob raug txwv tsis pub siv cov khoom no.
Cov kab mob uas txawv txav ntawm calcium metabolism: xws li hyperparathyroidism thiab lub raum pob zeb, thawj kab mob yuav tsum tau kho ua ntej.
IV. Kev npaj calcium supplementation
Kev ntsuas yooj yim
Kev noj zaub mov calcium ntxiv: 800-1200 mg ntawm calcium ib hnub (xws li mis nyuj, cheese, taum paj, zaub ntsuab tsaus).
Vitamin D supplementation: Yog tias lub hnub tsis txaus, noj vitamin D3 ntawm qhov ncauj (400-2000 IU ib hnub, raws li kws kho mob tau sau tseg).
Kev cuam tshuam kho mob
Calcium deficiency: Calcium supplementation (xws li calcium carbonate, calcium citrate) yuav tsum tau.
Kab mob-kwv yees tsis txaus calcium: Piv txwv li, kab mob raum ntev yuav tsum tau siv cov tshuaj vitamin D (calcitriol).
Lub luag haujlwm ntawm UVB lub teeb: Los ntawm kev txhawb nqa vitamin D synthesis, nws ncaj qha txhim kho calcium nqus thiab haum rau calcium deficiency los ntawm vitamin D tsis txaus.
Cov kev ntsuas yuav tsum tau muaj: kev noj zaub mov kom raug, kev siv lub qhov ncauj, kev kho mob thawj zaug.
Kev ceeb toom txog kev pheej hmoo: Tsis txhob raug ntau dhau, thiab muab qhov tseem ceeb rau kev ntxiv los ntawm lub hnub ci ntuj (teev me me) lossis kev kho mob - cov khoom siv kho mob qib. koj tuaj yeem nrhiav tau qib kho mob phototherapy teeb rau https://www.benweilight.com/professional-lighting/uv-lighting/320nm-365nm-300nm-uvb-led-light-100w-200w.html
