Calcium Hydroxyapatite/HAP

Hydroxyapatite, anonziwohydroxylapatite(HA), inowanzoitika mamineral fomu ye calcium apatite ine formula Ca5 (PO4) 3 (OH), asi inowanzonyorwa Ca10 (PO4) 6 (OH) 2 kuratidza kuti crystal unit cell inoumbwa nezvikamu zviviri. Hydroxyapatite ndiyo hydroxyl endmember yeboka rakaoma reapatite. Purehydroxyapatite upfuchena. Apatites anongoitika anogona, zvisinei, zvakare ane brown, yero, kana girinhi mavara, anofananidzwa nekubuda kwemazino fluorosis.
Kusvika ku50% nehuwandu uye 70% nekurema kwepfupa revanhu imhando yakagadziridzwa yehydroxyapatite, inozivikanwa sefupa remaminerari.Carbonated calcium-deficient hydroxyapatite ndiyo maminerari makuru ayo enamel yemazino uye dentini inoumbwa. Hydroxyapatite makristasi anowanikwawo mune zvidiki calcifications, mukati mepineal gland uye zvimwe zvimiro, zvinozivikanwa se corpora arenacea kana 'brain sand'.

Application

1. Hydroxyapatite iripo mumapfupa nemazino; pfupa rinogadzirwa zvakanyanya neHA makristasi akapindirwa mune collagen matrix - 65 kusvika 70% yehuremu hwebhonzo HA. Saizvozvo HA i70 kusvika 80% yehuremu hwedentin uye enamel mumazino. Mune enamel, iyo matrix yeHA inoumbwa neamelogenins uye enamelins panzvimbo ye collagen.
Hydroxylapatite inoisa mumatendon akatenderedza majoini inoguma mune yekurapa mamiriro calcific tendinitis.

2. HA iri kuwedzera kushandiswa kugadziramapfupa ekubatanidza zvinhuuyewo mazino prosthetics uye kugadzirisa. Mamwe maimplants, eg kuisirwa hudyu, mazino anodyarwa uye bhonzo conduction implants, akaiswa HA. Sezvo mwero wekuparara kweiyo hydroxyapatite mu-vivo, yakatenderedza 10 wt% pagore, yakaderera zvakanyanya pane yekukura kweiyo ichangobva kuumbwa pfupa tishu, mukushandiswa kwayo sechinhu chinotsiva pfupa, nzira dziri kutsvakwa kuti dziwedzere kunyungudika kwayo uye. nokudaro kukurudzira zviri nani bioactivity.

3. Microcrystalline hydroxyapatite (MH) inotengeswa se "bone-building" inowedzera nepamusoro-soro mukuenzanisa ne calcium.
