Vitamin K. Vitamin K yog cofactor rau enzyme lub luag haujlwm rau tshuaj lom neeg uas tswj ntshav coagulation yam - prothrombin; Cov xwm txheej VII, IX, thiab X; thiab proteins C thiab S. Vim vitamin K tau muab rau hauv cov zaub mov noj thiab los ntawm kev sib sau ntawm cov kab mob hauv plab, qhov tsis zoo tsis tshwm sim.
Tsis tas li ntawd, leej twg ntawm cov vitamins hauv qab no yog xav tau rau kev tsim cov prothrombin thiab lwm yam ua rau txhaws?
Vitamin K. Vitamin K, ib qho ntawm ntau cov roj-soluble naphthoquinone tebchaw. Vitamin K (los ntawm Danish lo lus koagulation) yog xav tau rau synthesis ntawm ob peb cov ntshav coagulation yam , suav nrog prothrombin thiab yam VII, IX, thiab X. A form of vitamin K hu ua phylloquinone ( vitamin K1) yog tsim los ntawm cov nroj tsuag.
Ib yam li ntawd, 12 yam ntawm cov ntshav txhaws yog dab tsi? Cov hauv qab no yog coagulation yam thiab lawv cov npe:
- Factor I - fibrinogen.
- Factor II - prothrombin.
- Factor III - cov ntaub so ntswg thromboplastin (cov ntaub so ntswg)
- Factor IV - ionized calcium (Ca++)
- Factor V - labile factor lossis proaccelerin.
- Factor VI - unassigned.
- Factor VII - qhov ruaj khov lossis proconvertin.
Tsuas yog li ntawd, dab tsi yog cov yam ntxwv ntawm coagulation?
Txoj hauv kev zoo tshaj plaws X, V, II, I, thiab XIII tseem hu ua Stuart-Prower factor, proaccelerin, prothrombin , fibrinogen cov , thiab fibrin-stabilizing yam feem. Clotting factor IV yog calcium ion uas ua lub luag haujlwm tseem ceeb hauv 3 txoj hauv kev.
Qhov twg yog cov khoom ua kom cov ntshav txhaws?
Hauv daim siab, hepatocytes koom nrog hauv kev sib txuas ntawm cov ntshav feem ntau coagulation yam , xws li fibrinogen, prothrombin, yam V, VII, IX, X, XI, XII, ntxiv rau cov protein C thiab S, thiab antithrombin, hos lub siab sinusoidal endothelial cells tsim khoom VIII thiab von Willebrand yam.

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?
Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws
Dab tsi ntawm cov hauv qab no yog qhov kev txhawj xeeb tseem ceeb ntawm cov kab mob ntshav qab zib?
Ntawm qhov kev txhawj xeeb tseem ceeb yog tus kab mob tib neeg tiv thaiv kab mob (HIV) thiab kab mob siab B thiab kab mob siab C. Tus txheej txheem teeb tsa kev xav tau rau cov tswv ntiav haujlwm nrog cov neeg ua haujlwm raug cov ntshav lossis lwm yam khoom muaj peev xwm kis tau
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Cov kab mob dab tsi yog txuas nrog kev hloov pauv ntawm cov qog nqaij hlav qog ntshav?
Kev hloov pauv ntawm ob lwm cov qog qog ua qog, BRCA1 thiab BRCA2, yog lub luag haujlwm rau cov kab mob qog noj ntshav ntawm lub mis, uas suav txog 5 txog 10% ntawm tag nrho cov mob qog noj ntshav mis
