Cov Kws Tshaj Lij Tshaj Tawm Txog Oxidized Regenerated Cellulose

Muaj kev xav sib txawv ntawm lub tshuab ua haujlwm. Ua ntej, vim nws qhov ntxhib saum npoo, nws tuaj yeem txhawb platelet rupture, tsim ntau cov platelet coagulation yam, ua rau fibrinogen hloov mus ua fibrin, daim ntawv thrombi, thaiv cov hlab ntsha puas thiab tsis los ntshav. Nws cov nyhuv hemostatic hauv zos ntawm oxidized regenerated cellulose yog tias cov pab pawg hydroxyl hauv cellulose tsim cross-links nrog Ca2+ hauv plasma los tsim cov gelatinous ntshav txhaws, uas thaiv cov hlab ntsha puas thiab tsis los ntshav. Qhov thib peb, nws ntseeg tau tias oxidized regenerated cellulose tsis koom rau hauv lub cev lub cev coagulation mechanism, tab sis thaum nws los rau hauv kev sib cuag nrog cov ntshav, cellulose hloov mus rau reddish xim av los yog dub gelatin blocks, uas txhawb kev tsim cov ntshav txhaws.
