ntshav ntshav Thaum cov ntshav txhaws tau qhib, fibrinogen circulating hauv cov ntshav hloov mus rau fibrin, uas nyob rau hauv lem pab tsim cov ntshav khov ruaj khov ntawm qhov chaw ntawm vascular cuam tshuam.
fibrinogen nyob qhov twg hauv cov ntshav?
Fibrinogen, lossis yam kuv, yog cov ntshav plasma protein uas tau tsim hauv lub siab. Fibrinogen yog ib qho ntawm 13 coagulation yam ua lub luag haujlwm rau cov ntshav txhaws. Thaum koj pib los ntshav, koj lub cev pib txheej txheem hu ua coagulation cascade, los yog coagulation cascade.
fibrin ua dab tsi hauv lub cev?
Fibrin (tseem hu ua Factor Ia) yog cov protein uas tsis yog-globular koom nrog hauv cov ntshav txhaws Nws yog tsim los ntawm kev txiav txim ntawm protease thrombin ntawm fibrinogen, uas ua rau nws mus rau polymerize. Cov polymerized fibrin, ua ke nrog cov platelets, ua rau hemostatic ntsaws lossis txhaws ntawm qhov chaw mob.
fibrin ua haujlwm li cas?
Fibrin yog nquag tsim rau ntawm qhov chaw ntawm cov platelets qhib, nrog kev tshwm sim ntawm ob qho tib si extrinsic (TF, FVII) thiab intrinsic (FXII, FXI) coagulation txoj hauv kev. Platelets txuas ntxiv hloov cov qauv fibrin network thiab tswj kev cog lus ntawm cov hlab ntsha (Daim duab 1B).
Dab tsi yog fibrinogen hauv cov ntshav?
Fibrinogen yog cov protein, tshwj xeeb yog qhov ua rau txhaws ntshav (factor I), uas yog qhov tseem ceeb rau kev tsim cov ntshav txhaws. Muaj ob hom kev ntsuam xyuas los ntsuas fibrinogen. Kev kuaj mob fibrinogen ntsuas seb fibrinogen ua haujlwm zoo li cas hauv kev pab tsim cov ntshav txhaws.

Qhov twg ntawm cov no tsim los ntawm cov qog ntshav qog ntshav?
2. Lymphocytes tsim los ntawm cov qog ntshav qog ntshav. Hematopoietic stem cells-cov qia hlwb uas muaj ntau lub zog uas ua rau tag nrho cov qe ntshav sib txawv rau hauv myeloid thiab lymphoid progenitor cells. Cov qe ntshav liab, platelets, thiab cov qe ntshav dawb myeloid (granular thiab agranular) yog los ntawm myeloid progenitor cells .
Puas yog mob qog noj ntshav ntawm cov qog ntshav qog ntshav?
Muaj ob peb yam ntawm ntau txoj kev kho mob qog noj ntshav muaj los kho cov qog nqaij hlav thiab qog nqaij hlav hauv lawv ntau theem. Tsis yog txhua tus qog nqaij hlav qog nqaij hlav qog noj ntshav yog mob qog noj ntshavNtau yam tuaj yeem kho thiab tshem tawm raws sijhawm.
Dab tsi ntawm cov hauv qab no yog kev ua haujlwm ntawm cov qog ntshav qog ntshav?
Lub luag haujlwm tseem ceeb ntawm cov qog ntshav qog ntshav yog txhawm rau thauj cov qog ntshav, cov kua dej uas muaj cov kab mob sib tua cov qe ntshav dawb, thoob plaws hauv lub cev… Cov hlab ntsha txuas nrog cov qog ntshav, qhov twg cov qog ntshav yog lim.
Cov qe ntshav dawb puas muaj mob qog noj ntshav mis?
"Cov kev tshawb fawb txog kev kis kabmob kis tau zoo qhia tias cov poj niam uas muaj cov lej leukocyte ntau dua, lossis qee yam kab mob autoimmune, tuaj yeem nce nrog mob qog noj ntshav." Puas yog mob qog noj ntshav ua rau cov ntshav dawb suav ntau?
Puas yog cov qog ntshav qog ntshav qog ntshav ntev ntev?
Chronic lymphocytic leukemia feem ntau tsis tau txiav txim siab tias muaj keeb kwm caj ces. Txawm li cas los xij, muaj pov thawj tsis ncaj qha uas ib pawg ntawm CLL cov ntaub ntawv yuav raug muab rau cov qub txeeg qub teg ntawm autosomal dominant noob .
