A Ntoo teeb kev tshuaj xyuas yog txheej txheem uas siv transillumination (cov lub teeb ) txhawm rau txheeb xyuas kab mob ntawm daim tawv nqaij lossis kab mob hu ua fungal. Nws kuj tseem tuaj yeem kuaj pom cov tawv nqaij tsis xws luag xws li vitiligo thiab lwm yam tawv nqaij tsis xws luag.
Zoo ib yam tuaj yeem nug, Puas yog Ntoo lub teeb tsuas yog lub teeb dub?
A teeb pom kev (los yog ntau zaus lub teeb dub ), tseem hu ua UV-A lub teeb , Ntoo teeb , los yog ultraviolet lub teeb , yog a teeb uas tawm ntev-nthwv dej (UV-A) ultraviolet lub teeb thiab pom tsawg heev lub teeb . Teeb taws teeb uas muaj cov lim no muaj teeb pom kev zoo kev tsim khoom lag luam uas suav nrog cov ntawv "BLB".
Qhov thib ob, dab tsi fluoresces hauv qab Ntoo lub teeb? Qee qhov ntawm ntau qhov teeb meem ntawm daim tawv nqaij uas tuaj yeem ua fluoresce nyob rau hauv Ntoo qhov kev kuaj pom muaj xws li hauv qab no:
- Kab mob sib kis.
- Kab mob sib kis.
- Lub taub hau ntshauv thiab nits.
- Erythrasma.
- Porphyria cutanea tarda.
- Vitiligo.
- Lwm yam teeb meem xim.
Ib yam nkaus, tib neeg nug, vitiligo zoo li cas nyob hauv Ntoo lub teeb?
Cov no suav nrog vitiligo , kev loj hlob ntawm macular hypomelanosis, ua xua, tinea capitis, erythrasma, thiab pityriasis versicolor [4, 5]. Nyob hauv Ntoo lub teeb , vitiligo qhov txhab (daim duab 1) tshwm rau pom dawb thiab ua kom pom meej, raws li qhov autofluorescence ntawm dermal collagen.
Ntoo lub teeb siv li cas hauv kev kuaj mob ntawm tinea capitis?
Xyoo 1925, Margarot thiab Deveze tau pom tias muaj cov plaub hau sib kis thiab qee cov kab mob hu ua kab mob fluoresce hauv ultraviolet teeb. Lub teeb dub feem ntau yog hu ua Ntoo teeb . Lub teeb raug lim los ntawm a Ntoo nickel oxide iav (barium silicate nrog nickel oxide), uas tso cai tsuas yog ntev ultraviolet rays dhau (ncov ntawm 365 nm).

Puas yog lub teeb liab hluav taws xob uas feem ntau txav los ntawm lub cev ntawm tes mus rau lub axon mus rau lub dav hlau axon?
Qhov txiaj ntsig zoo no suav nrog qhov muaj peev xwm ua tau: lub teeb liab hluav taws xob uas ib txwm txav los ntawm lub cev ntawm tes los ntawm lub axon mus rau lub dav hlau axon
Qhov tshuaj lom cov ntoo ntoo ntoo ntoo thiab sumac loj hlob nyob qhov twg?
Tshuaj lom cov ntoo ntoo, cov ntoo ntoo muaj tshuaj lom, thiab cov tshuaj lom tuaj yeem pom nyob hauv ntau thaj chaw hauv Tebchaws Meskas, tshwj tsis yog Alaska, Hawaii, thiab thaj chaw suab puam ntawm Sab Hnub Poob. Hauv qee thaj chaw ntawm lub tebchaws (Sab Hnub Tuaj, Sab Hnub Poob, thiab Sab Qab Teb), cov tshuaj ntsuab ivygrows ua cov hmab
Puas muaj tshuaj lom cov ntoo ntoo tua ntoo?
A: Cov tshuaj ntsuab tsis tuaj yeem nqus lub neej los ntawm cov ntoo lossis 'choke' ntoo, tab sis cov hmab tuaj yeem loj hlob thiab hla tsob ntoo ceg ntoo. Thaum qhov ntawd tshwm sim, cov tshuaj lom cov ntoo ntoo tuaj yeem thaiv lub hnub ci mus rau tsob ntoo nplooj ntoo, thiab thaum lub sijhawm ntawd, nws tuaj yeem tawg thiab txawm tua tsob ntoo
Puas yog lub teeb pom kev zoo ib yam li lub teeb ntoo?
Lub teeb dub (lossis feem ntau lub teeb dub), tseem hu ua UV-A lub teeb, Ntoo lub teeb, lossis lub teeb ultraviolet, yog lub teeb uas tawm lub teeb ntev (UV-A) ultraviolet lub teeb thiab pom lub teeb me ntsis
Qhov twg ntawm lub qhov muag muaj lub teeb pom kev uas hloov pauv lub teeb liab mus rau hauv kev xav ntawm lub paj hlwb?
Lub teeb yog mapped raws li ib tug duab nyob rau saum npoo ntawm lub retina los ntawm activating ib tug series ntawm lub teeb-sensitive hlwb hu ua rods thiab cones. Cov hlwb photoreceptor no hloov lub teeb mus rau hluav taws xob uas tau xa mus rau lub hlwb los ntawm cov hlab ntsha
