Ib qho ntawm cov haujlwm tshem tawm ntawm hepatocytes yog hloov kho ammonia rau hauv urea rau kev tso tawm. Cov tshaj plaws organelle hauv lub siab lub cev yog tus du endoplasmic reticulum.
Ib yam li ntawd, nws tau nug, cov cell tsim lub siab li cas?
Hepatocytes yog cuboidal epithelial cells uas kab cov sinusoids thiab ua rau feem ntau ntawm cov cell hauv lub siab. Hepatocytes ua feem ntau ntawm lub siab ua haujlwm - metabolism, khaws cia, zom zaub mov, thiab tsim cov kua tsib.
Ib sab saum toj no, muaj pes tsawg lobules muaj lub siab? Hepatic microscopic architecture hauv txhua peb hom tuaj yeem piav qhia hauv cov ntsiab lus ntawm "classical cev lobules . " Cov no yog cov txheej txheem uas muaj ntau yam nrog cov kab hauv qhov chaw ntawm ib puag ncig ib puag ncig cov hlab ntshav hauv nruab nrab. Tib neeg siab yog kwv yees kom muaj kwv yees li 1 lab classical cev lobules.
Ntxiv mus, dab tsi yog lobule hauv daim siab?
Cov lobules ntawm siab , los yog lub cev lobules , yog kev faib me me ntawm siab txhais ntawm lub tshuab me me (histological) nplai. Lub siab lub lobule yog lub tsev thaiv ntawm siab cov ntaub so ntswg, suav nrog lub portal triad, hepatocytes tau teeb tsa nyob rau hauv txoj kab ncaj nruab nrab ntawm cov kab ke capillary, thiab lub hauv paus leeg.
Parenchymal cell ntawm daim siab yog dab tsi?
Cov parenchymal cells ntawm daim siab yog hepatocytes. Cov polygonal no hlwb tau koom nrog ib leeg hauv cov phaj anastomosing, nrog cov ciam teb uas ntsib lub sinusoids lossis cov hepatocytes nyob ib sab.

Dab tsi yog lub npe ntawm cov cell uas ua cov hlua hauv daim siab lobule?
Hauv qhov chaw Disse (qhov chaw nyob hauv qab endothelium), muaj lwm lub cell stromal, suav nrog cov cell stellate thiab antigen-nthuav tawm cov dendritic cells. Hepatocytes tsim cov hlua uas yog 2 lub hlwb tuab. Biliary canaliculi nyob nruab nrab ntawm ob txoj hlua ntawm cov xovtooj ntawm sab nraub qaum ntawm sinusoids
Cov hom lipoprotein twg hauv qab no muaj qhov feem pua siab tshaj plaws ntawm cov protein?
HDL yog qhov tsawg tshaj plaws ntawm cov lipoprotein hais. Nws yog qhov ntom tshaj plaws vim tias nws muaj qhov feem ntau ntawm cov protein rau lipids. Nws cov apolipoproteins ntau tshaj yog apo A-I thiab apo A-II
Cov mob qog noj ntshav tawv nqaij twg muaj cov neeg tuag ntau tshaj plaws thiab vim li cas?
Melanoma yog qhov tsawg tshaj plaws, tab sis feem ntau cov kab mob qog nqaij hlav tuag taus, suav txog tsuas yog li 1% ntawm txhua tus neeg mob, tab sis feem ntau ntawm daim tawv nqaij tuag
Cov hlab ntsha twg cov ntshav siab mus txog qhov ntsuas siab tshaj plaws?
Cov hlab ntsha loj tau txais lub siab tshaj plaws ntawm cov ntshav ntws thiab ntau tuab thiab ywj kom haum rau qhov siab. Cov hlab ntsha me, xws li arterioles, muaj cov leeg du uas sib cog lus lossis so kom tswj cov ntshav ntws mus rau qee qhov ntawm lub cev
Dab tsi yog cov tshuaj cholesterol zoo tshaj plaws uas muaj kev phiv tsawg tshaj plaws?
Hauv kev tshuaj xyuas ntawm 135 cov kev tshawb fawb yav dhau los, uas suav nrog ze li ntawm 250,000 tus neeg ua ke, cov kws tshawb fawb pom tias cov tshuaj simvastatin (Zocor) thiab pravastatin (Pravachol) muaj qhov cuam tshuam tsawg tshaj plaws hauv cov tshuaj no
