Hlau tau khaws cia, feem ntau hauv lub siab, zoo li ferritin hmoov los yog hemosiderin tshuaj . Ferritin yog cov protein uas muaj peev xwm kwv yees li 4500 hlau (III) ions rau cov protein molecule. Qhov no yog daim ntawv tseem ceeb ntawm cov hlau cia. Qhov no hu ua hemosiderin tshuaj ; nws yog physiologically muaj.
Tom qab ntawd, qhov sib txawv ntawm ferritin thiab hemosiderin yog dab tsi?
Ferritin yog dej yooj yim thiab ua kom luv ob qho tib si, T1 thiab T2 so, nrog rau qhov tshwm sim hloov pauv ntawm MR cov duab. Hemosiderin , cov khoom lag luam degradation ntawm ferritin hmoov , yog dej-tsis yaj nrog lub zog T2 ua kom luv dua li ferritin hmoov.
Tom qab ntawd, lo lus nug yog, Hemosiderin txhais li cas? Kev kho mob Txhais ntawm hemosiderin tshuaj : cov xim daj daj xim daj ua los ntawm kev tawg ntawm hemoglobin, pom hauv phagocytes thiab hauv cov nqaij tshwj xeeb hauv kev cuam tshuam ntawm cov hlau metabolism (zoo li hauv hemochromatosis, hemosiderosis, lossis qee yam anemias), thiab muaj cov ntsiab lus tseem ceeb ntawm colloidal ferric oxide - piv ferritin.
Ua li no, Hemosiderin ua haujlwm li cas?
Hemosiderin los yog haemosiderin yog cov hlau khaws cia. Kev tawg ntawm heme ua rau nce biliverdin thiab hlau. Tom qab ntawd lub cev ntxiab cov hlau tso tawm thiab khaws nws li hemosiderin tshuaj hauv cov ntaub so ntswg.
Dab tsi ua rau Hemosiderin?
Hemosiderin staining tshwm sim thaum cov qe ntshav liab tau tawg, ua hemoglobin yuav tsum khaws cia raws li hemosiderin tshuaj . Koj cov qe ntshav dawb, lossis cov kab ke tiv thaiv kab mob hauv lub cev, tuaj yeem tshem qee cov hlau ntau dhau tso rau hauv koj cov tawv nqaij. Tab sis muaj qee qhov kev kho mob uas tuaj yeem cuam tshuam cov txheej txheem no, ua rau muaj qhov tsis huv.
