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.
