Cov yam ntxwv

Cov khoom β-TCP zoo ib yam li cov pob txha pob txha thiab yog cov hmoov dawb amorphous tsis muaj ntxhiab. Ruaj khov hauv huab cua, lwj hauv dej kub, yaj hauv dilute hydrochloric acid thiab nitric acid, yuav luag tsis yaj hauv dej, ethanol thiab acetic acid. Kev sib raug zoo ntawm cov kab mob, kev puas tsuaj hauv qab ib puag ncig physiological, nqus tau los ntawm cov ntaub so ntswg.

β-tricalcium phosphate (β-TCP) muaj kev puas tsuaj zoo, biocompatibility thiab osteoinductive muaj peev xwm. Tom qab raug cog rau hauv tib neeg lub cev, cov calcium thiab phosphorus uas lwj tuaj yeem nkag mus rau hauv lub cev muaj sia thiab tsim cov pob txha tshiab, yog li nws tau siv dav. Kho cov pob txha. Txawm li cas los xij, nws qhov tawv tsis zoo, brittle, thiab lub peev xwm thauj khoom tsis zoo. Poly L-lactic acid (PLLA) kuj tau siv rau hauv kev kho cov pob txha vim nws qhov biocompatibility zoo thiab biodegradability.

Cov ntawv thov

Tricalcium phosphate muaj kev sib raug zoo, kev ua haujlwm zoo, thiab kev lwj ntawm lub cev. Nws yog ib yam khoom siv kho thiab hloov cov nqaij tawv zoo tshaj plaws rau tib neeg lub cev thiab tau raug saib xyuas zoo hauv kev tsim kho biomedical. Ib hom tshwj xeeb ntawm tricalcium phosphate, beta-tricalcium phosphate, feem ntau siv hauv tshuaj. Kev sib raug zoo, kev ua haujlwm zoo, thiab kev lwj ntawm lub cev. Nws yog ib yam khoom siv kho thiab hloov cov nqaij tawv zoo tshaj plaws. Ua ib yam khoom siv raw rau pob txha cuav, nws tau siv dav hauv kev kho pob txha, kev phais yas thiab kev phais kom zoo nkauj, kev phais hniav, kev kho vim raug mob, pob txha tsis zoo thiab kev sib koom ua ke los ntawm cov qog, o, kab mob pob txha, thiab lwm yam. Nws tuaj yeem ntxiv rau hauv cov khoom noj ua cov khoom noj muaj kev nyab xeeb kom txhim kho kev noj calcium, thiab nws kuj tuaj yeem siv los tiv thaiv lossis kho cov tsos mob ntawm kev tsis txaus calcium. Tib lub sijhawm, nws kuj tuaj yeem siv ua tus neeg sawv cev tiv thaiv kev sib sau ua ke, tus neeg kho pH, tus neeg sawv cev buffering, thiab lwm yam hauv cov khoom noj.

β-tricalcium phosphate feem ntau yog ua los ntawm calcium thiab phosphorus, thiab nws cov khoom sib xyaw zoo ib yam li cov khoom inorganic ntawm cov pob txha matrix, thiab sib xyaw zoo nrog pob txha. Cov tsiaj lossis cov hlwb tib neeg tuaj yeem loj hlob, sib txawv thiab ntau ntxiv ntawm cov khoom β-tricalcium phosphate. Los ntawm ntau qhov kev tshawb fawb sim, nws tau ua pov thawj tias β-tricalcium phosphate tsis muaj kev tsis haum rau cov pob txha hematopoietic ua haujlwm, tsis muaj kev tsis lees paub, tsis muaj kev lom tshuaj lom, tsis muaj mob qog noj ntshav, tsis muaj kev ua xua. Yog li ntawd, β-tricalcium phosphate tuaj yeem siv dav hauv kev sib koom ua ke thiab pob txha caj qaum, raug mob ceg, phais qhov ncauj thiab maxillofacial, phais plawv, thiab sau cov kab noj hniav. Nrog rau kev tshawb fawb tob zuj zus ntawm β-tricalcium phosphate, nws cov ntawv thov kuj tau sib txawv, thiab nws tau pom tias muaj kev ua tau zoo hauv kev kho mob hauv tsev kho mob.
