Anticoagulants xws li heparin lossis warfarin (tseem hu ua Coumadin) qeeb koj lub cev txheej txheem ntawm kev ua txhaws . Tshuaj Antiplatelet, xws li tshuaj aspirin, tiv thaiv cov qe ntshav hu ua platelets los ua ke ua ke rau form ib clot . Thaum koj noj cov ntshav nyias, ua raws li cov lus qhia ua tib zoo.
Tom qab ntawd, ib tus neeg kuj tseem yuav nug tau, yuav ua li cas warfarin txwv tsis pub cov ntshav khov?
Warfarin ua rau lub cev tsis muaj peev xwm tsim tau cov ntshav txhaws los ntawm thaiv cov tsim ntawm vitamin K -dependant txhaws yam. Vitamin K yuav tsum tau ua txhaws yam thiab tiv thaiv los ntshav.
Tsis tas li ntawd, qhov twg anticoagulant inhibits thrombin tsim? Heparin
Nyob rau hauv no txoj kev, dab tsi yog lub mechanism ntawm kev txiav txim rau anticoagulants?
Anticoagulants ua tiav lawv cov txiaj ntsig los ntawm kev ua kom cov synthesis lossis kev ua haujlwm ntawm ntau yam txheej txheem cotting uas feem ntau tshwm sim hauv cov ntshav. Cov tshuaj no feem ntau yog siv los tiv thaiv kev tsim cov ntshav txhaws (thrombi) hauv cov hlab ntsha lossis cov hlab ntsha lossis qhov loj ntawm cov hlab ntsha uas nyob hauv cov hlab ntsha.
Qhov twg cov tshuaj anticoagulants ua haujlwm nyob rau hauv clotting cascade?
Heparin yog ib qho anticoagulant uas yog muab los ntawm kev txhaj tshuaj. Nws ua tau pom tias qhov inhibition ntawm Factors II (Prothrombin), VII, IX thiab X muaj qhov cuam tshuam rau kev tsim cov fibrin ruaj khov. clot . Qhov inhibition ntawm Factor VII muaj qhov cuam tshuam ncaj qha rau txoj hauv kev extrinsic.

Hom ntshav twg muaj ob qho tshuaj tiv thaiv A thiab tiv thaiv B hauv lawv cov ntshav?
ABO antigens thiab cov tshuaj tiv thaiv Lub npe ntawm Pawg Ntshav Antigens muaj nyob rau ntawm cov xov tooj liab liab ABO cov tshuaj tiv thaiv tam sim no hauv ntshav Hom O nil anti-A thiab anti-B Hom A A antigen anti-B Type B B antigen anti-A Type AB A thiab B antigens nil
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
Puas yog kev tsim cov tshuaj tiv thaiv kab mob tsis yog lub cev tiv thaiv?
Kev tiv thaiv tshwj xeeb suav nrog teeb meem anatomic, inhibitors, phagocytosis, ua npaws, mob, thiab IFN. Cov kev tiv thaiv tshwj xeeb muaj xws li tshuaj tiv thaiv kab mob thiab kev tiv thaiv kab mob ntawm tes
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
Cov tshuaj tiv thaiv twg yog tsim ua ntej hauv kev tiv thaiv kab mob?
IgM tshuaj tiv thaiv
