acnes), Gram-positive anaerobic bacterium, yog kab mob sib kis hauv tib neeg tawv nqaij . Zoo li tib neeg cov cell, cov kab mob tsim tawm porphyrins , uas nthuav tawm cov khoom siv fluorescence thiab ua kom pom cov kab mob nrog Ntoo lub teeb. Hauv kev tshuaj xyuas no, peb piv cov porphyrin biosynthesis hauv tib neeg thiab P.
Ib yam li ib tus tuaj yeem nug, qhov kev sim porphyrin yog dab tsi?
Porphyrin xeem ntsuas qib ntawm cov porphyrins hauv koj cov ntshav, zis, lossis quav. Porphyrins yog cov tshuaj uas pab ua hemoglobin, ib hom protein nyob hauv koj cov qe ntshav liab. Hemoglobin nqa oxygen los ntawm koj lub ntsws mus rau tag nrho koj lub cev. Tab sis ntau dhau cov porphyrin tej zaum yuav txhais tau tias koj muaj hom porphyria.
Ib yam li ntawd, porphyria ua dab tsi rau lub cev? Porphyria (por-FEAR-e-uh) hais txog pab pawg ntawm cov teeb meem uas tshwm sim los ntawm kev sib sau ntawm cov tshuaj ntuj uas tsim cov tshuaj porphyrin hauv koj lub cev. lub cev . Porphyrins yog Qhov tseem ceeb rau kev ua haujlwm ntawm hemoglobin - ib qho protein hauv koj cov qe ntshav liab uas txuas rau porphyrin, khi hlau, thiab nqa oxygen rau koj lub cev thiab cov ntaub so ntswg.
Qhov thib ob, qhov ua rau porphyria yog dab tsi?
Cov teeb meem no feem ntau tau txais, txhais tau tias lawv yog ua los ntawm kev txawv txav hauv cov noob dhau los ntawm niam txiv mus rau menyuam. Thaum ib tus neeg muaj porphyria , cov cell tsis hloov pauv tshuaj lom neeg lub cev hu ua cov porphyrins thiab porphyrin precursors rau hauv heme, cov khoom uas muab cov ntshav nws cov xim liab.
Tus mob porphyria zoo li cas?
Feem ntau tau tshaj tawm cov tsos mob tsis zoo yog qhov mob hnyav cuam tshuam rau lub plab, nraub qaum, lossis ceg tawv; lwm yam nres cov cim thiab tsos mob suav nrog xeev siab thiab ntuav, cem quav, kub siab, lub cev tsis muaj zog, pw tsis tsaug zog, lossis ntxhov siab [1–3, 5].

Dab tsi yog txheej txheej sab saum toj ntawm daim tawv nqaij nyob ib sab ntawm daim tawv nqaij?
Lub dermis txuas cov epidermis mus rau hypodermis, thiab muab lub zog thiab kev ywj pheej vim muaj cov collagen thiab elastin fibers. Nws tsuas muaj ob txheej: txheej txheej papillary nrog papillae uas nthuav mus rau hauv daim tawv nqaij thiab qis dua, txheej txheej reticular uas muaj cov ntaub so ntswg sib txuas xoob
Cov tawv nqaij tawv tshaj plaws ntawm koj lub cev yog dab tsi?
Lub Epidermis Nws yog tuab tshaj ntawm ob txhais tes thiab ob txhais taw (1.5 millimeters)
Koj ua li cas tiv thaiv cov tawv nqaij tawv nqaij?
Kev tiv thaiv thiab kev tiv thaiv tej zaum yuav muaj xws li cov hauv qab no: Kev zam ntawm tus kab mob staphylococcal thawj zaug uas yuav ua rau muaj cov kab mob lom. Kev kho mob raws sijhawm ntawm cov kab mob staphylococcal tsim. Kev txheeb xyuas thiab kev kho tus kab mob asymptomatic
Dab tsi yog qhov txawv ntawm daim tawv nqaij thiab daim tawv nqaij daim ntawv xeem?
Qauv: Sib sib zog nqus ntawm daim tawv nqaij; connective ntaub so ntswg muaj li ntawm ob txheej. Muaj nuj nqi: Muaj lub luag haujlwm rau cov txheej txheem muaj zog thiab yoog raws ntawm daim tawv nqaij; lub epidermis pauv cov pa roj, cov khoom noj, thiab cov khoom pov tseg nrog cov hlab ntsha hauv lub dermis
Puas yog lo lus dav dav txhais tau tias yog mob ntawm daim tawv nqaij lossis pob khaus uas tuaj yeem muaj ntau yam ua rau nws yog ib qho cim ntawm ntau hom tawv nqaij tsis xws luag?
Dermatitis yog lo lus dav dav uas piav txog kev ua rau tawv nqaij. Dermatitis yog ib yam mob uas muaj ntau yam ua rau thiab tshwm sim ntau yam. Nws feem ntau yog khaus, tawv nqaij qhuav los yog pob khaus ntawm daim tawv nqaij o, reddened
