Urobilin yog tsim dhau ntawm oxidation ntawm nws niam txiv compound uroblinogen. Urobilin yog tsim los ntawm kev degradation ntawm heme, cov xim liab hauv hemoglobin thiab cov qe ntshav liab (RBCs). RBCs muaj lub neej ntev li ntawm 120 hnub.
Urobilin hauv cov zis tuaj qhov twg?
Urobilin yog tsim los ntawm kev degradation ntawm heme, uas yog thawj zaug degraded los ntawm biliverdin rau bilirubin. Tom qab ntawd bilirubin raug tso tawm raws li cov kua tsib, uas yog ntxiv degraded los ntawm microbes tam sim no nyob rau hauv txoj hnyuv loj rau urobilinogen.
Bilirubinuria tshwm sim los ntawm dab tsi?
Cas. Feem ntau ua rau bilirubinuria yog kab mob hepatocellular. Ntau qhov ua rau tsis tshua muaj xws li kev mob tshwm sim, xws li Dubin-Johnson syndrome thiab Rotor syndrome.
Yuav ua li cas tshem tawm urobilinogen?
Urobilinogen feem ntau tawm hauv cov quav, tab sis ib feem me me tau nqus los ntawm txoj hnyuv, nkag mus rau hauv lub portal ncig, raug tshem tawm los ntawm lub siab, thiab tso rau hauv cov kua tsib.. Qhov uas tsis tau muab tshem tawm ntawm lub portal cov ntshav los ntawm lub siab nkag mus rau hauv lub systemic ncig thiab yog tawm los ntawm lub raum.
txoj hmoo ntawm urobilinogen yog dab tsi?
Nws yog dej soluble thiab tsis muaj xim. Urobilinogen muaj ntau txoj hmoo: ib nrab oxidation rau urobilin ib nrab reabsoption nyob rau hauv cov hnyuv me thiab recirculation rov qab mus rau lub siab - enterohepatic ncig reabsorption rau hauv cov ntshav thiab nkag mus rau lub raum rauexcretion.
