● Piv nrog PRP, tsis muaj exogenous additives yog siv nyob rau hauv kev npaj ntawm PRF, uas tsis txhob muaj kev pheej hmoo ntawm kev tiv thaiv kab mob, kab mob khaub thuas thiab coagulation dysfunction.Nws cov cuab yeej npaj tau yooj yim.Nws yog ib-kauj ruam centrifugation, uas tsuas yog yuav tsum tau centrifuged ntawm tsawg ceev tom qab noj cov ntshav mus rau hauv lub centrifuge raj.Cov khoom silicon nyob rau hauv lub iav centrifuge raj txhawb lub physiological polymerization ntawm platelet activation thiab fibrin, simulation ntawm physiological coagulation txheej txheem yog pib thiab tej yam ntuj tso clots yog sau.
● Los ntawm qhov kev xav ntawm ultrastructure, nws pom tau hais tias qhov sib txawv conformation ntawm fibrin reticular qauv yog lub ntsiab structural feature ntawm ob theem, thiab lawv yog obviously txawv nyob rau hauv ceev thiab hom.Qhov ceev ntawm fibrin yog txiav txim los ntawm qhov ntau ntawm nws cov khoom raw fibrinogen, thiab nws hom nyob ntawm tag nrho cov nyiaj ntawm thrombin thiab tus nqi polymerization.Nyob rau hauv cov txheej txheem kev npaj ntawm ib txwm PRP, cov polymerized fibrin yog ncaj qha muab pov tseg vim nws dissolution nyob rau hauv PPP.Yog li ntawd, thaum thrombin ntxiv rau hauv qib thib peb los txhawb kev coagulation, cov ntsiab lus ntawm fibrinogen tau txo qis heev, yog li qhov ceev ntawm lub network qauv ntawm polymerized fibrin yog qis dua li ntawm lub cev nqaij daim tawv, vim cov nyhuv ntawm Exogenous. Additives, siab thrombin concentration ua rau lub polymerization ceev ntawm fibrinogen ntau dua li cov tshuaj tiv thaiv physiological.Cov tsim fibrin network yog tsim los ntawm polymerization ntawm plaub molecules ntawm fibrinogen, uas yog nruj thiab tsis muaj elasticity, uas yog tsis haum rau sau cytokines thiab txhawb cell migration.Yog li ntawd, kev loj hlob ntawm PRF fibrin network yog qhov zoo dua li PRP, uas yog ze rau lub xeev lub cev.
