thromboplastin Ib pawg ntawm lipoprotein tebchaw pom meej tso tawm los ntawm ntshav platelets ntawm qhov chaw raug mob. Nyob rau hauv lub xub ntiag ntawm calcium ions thiab lwm yam, nws catalyses hloov dua siab tshiab ntawm prothrombin rau hauv thrombin thaum lub sij hawm cov ntshav txhaws.
Dab tsi tso tawm thromboplastin thaum lub sijhawm ntshav coagulation?
Kauj Ruam 1: Cov ntaub so ntswg raug mob (cov hlab ntsha)tso tawm thromboplastin thiab khaws cov platelets tso tawm cov txheej txheem platelet. Ob qho tib si thromboplastin thiab platelet yam cuam tshuam nrog cov txheej txheem txhaws hauv cov ntshav los tsim cov prothrombin activator.
Lub xovtooj twg tso tawm cov enzyme hu ua thromboplastin?
Kev sau platelets rupture thiab tso cov tshuaj uas ua ke nrog lwm cov ntshav Cheebtsam los tsim ib tug enzyme hu ua thromboplastin.
Puas yog thromboplastin cuam tshuam rau cov ntshav txhaws?
Raws li kev taw qhia ntawm cov hlwb, tshwj xeeb yog cov ntaub so ntswg raug mob, cov ntshav coagulation tau qhib thiab cov hlab ntsha fibrin tau tsim sai heev. Cov protein nyob rau saum npoo ntawm cov hlwb uas yog lub luag haujlwm rau kev pib ntshav txhaws yog hu ua tissue factor, lossis cov ntaub so ntswg thromboplastin.
cov ntaub so ntswg thromboplastin tuaj qhov twg?
Keeb kwm, thromboplastin yog ib lub chaw kuaj ntshav, feem ntau yog muab los ntawm placental sources, siv los soj ntsuam lub sij hawm prothrombin (PT). Thaum manipulated nyob rau hauv lub laboratory, ib tug derivative yuav ua tautsim hu ua ib nrab thromboplastin. Ib feem ntawm thromboplastin tau siv los ntsuas txoj hauv kev.
