I-Calcium Hydroxyapatite HAP CAS 1306-06-5

Inkcazelo emfutshane:

I-Calcium Hydroxyapatite/HAP
I-Hydroxyapatite, ebizwa ngokuba yi-hydroxylapatite (HA), yindlela yendalo ye-mineral apatite ye-calcium kunye ne-formula Ca5 (PO4) 3 (OH), kodwa ngokuqhelekileyo ibhaliwe Ca10 (PO4) 6 (OH) 2 ukubonisa ukuba iyunithi yekristale iseli yenza amaziko amabini. I-Hydroxyapatite yi-hydroxyl endmember yeqela le-apatite eliyinkimbinkimbi. I-hydroxyapatite powder ecocekileyo imhlophe. I-apatites eyenzeka ngokwemvelo inokuthi, nangona kunjalo, ibe nemibala emdaka, etyheli, okanye eluhlaza, xa kuthelekiswa nokutshintsha kwe-fluorosis yamazinyo.
Ukuya kuthi ga kwi-50% ngomthamo kunye ne-70% ngesisindo sethambo lomntu yindlela eguqulwayo ye-hydroxyapatite, eyaziwa ngokuba yi-bone mineral.Carbonated calcium-deficient hydroxyapatite iyona minerali ephambili apho i-enamel yamazinyo kunye ne-dentin yenziwe. Iikristale ze-Hydroxyapatite zikwafumaneka kwi-calcifications encinci, ngaphakathi kwe-pineal gland kunye nezinye izakhiwo, ezaziwa njenge-corpora arenacea okanye 'isanti yobuchopho'.

Icalcium Hydroxyapatite/HAP

Hydroxyapatite, ikwabizwaihydroxylapatite(HA), ifom ye-mineral eyenzeka ngokwemvelo ye-calcium apatite kunye ne-formula Ca5 (PO4) 3 (OH), kodwa ngokuqhelekileyo ibhaliwe Ca10 (PO4) 6 (OH) 2 ukubonisa ukuba i-crystal unit cell iquka amacandelo amabini. I-Hydroxyapatite yi-hydroxyl endmember yeqela le-apatite eliyinkimbinkimbi. Unyului-hydroxyapatite powderimhlophe. I-apatites eyenzeka ngokwemvelo inokuthi, nangona kunjalo, ibe nemibala emdaka, etyheli, okanye eluhlaza, xa kuthelekiswa nokutshintsha kwe-fluorosis yamazinyo.
Ukuya kuthi ga kwi-50% ngomthamo kunye ne-70% ngesisindo sethambo lomntu yindlela eguqulwayo ye-hydroxyapatite, eyaziwa ngokuba yi-bone mineral.Carbonated calcium-deficient hydroxyapatite iyona minerali ephambili apho i-enamel yamazinyo kunye ne-dentin yenziwe. Iikristale ze-Hydroxyapatite zikwafumaneka kwi-calcifications encinci, ngaphakathi kwe-pineal gland kunye nezinye izakhiwo, ezaziwa njenge-corpora arenacea okanye 'isanti yobuchopho'.

Isicelo

1. I-Hydroxyapatite ikhona kwithambo kunye namazinyo; ithambo lenziwe ngokuyinhloko ngeekristale ze-HA ezifakwe kwi-collagen matrix - i-65 ukuya kwi-70% yobunzima bethambo yi-HA. Ngokufanayo i-HA yi-70 ukuya kwi-80% yobunzima be-dentin kunye ne-enamel emazinyweni. Kwi-enamel, i-matrix ye-HA yenziwe nge-amelogenins kunye ne-enamelins endaweni ye-collagen.
I-Hydroxylapatite idiphozithi kwii-tendon ezijikeleze amalunga iphumela kwimeko yezonyango i-calcific tendinitis.

2. I-HA iya isetyenziselwa ukwenzaizixhobo zokuxhunyelelwa amathambokunye neprosthetics yamazinyo kunye nokulungiswa. Ezinye izinto ezifakelwayo, umz. ukufakelwa kwenyonga, ukufakelwa kwamazinyo kunye nokufakelwa kwamathambo, kuqatywe ngeHA. Njengoko izinga lokuchithwa kwe-hydroxyapatite in-vivo, malunga ne-10 wt% ngonyaka, liphantsi kakhulu kunezinga lokukhula kwezicubu ezisanda kwakhiwa, ekusetyenzisweni kwayo njengento yokubuyisela amathambo, iindlela ziyafunwa ukunyusa izinga lokunyibilika kwayo kunye. ngaloo ndlela ikhuthaza ukusebenza ngcono kwezinto eziphilayo.

3. I-Microcrystalline hydroxyapatite (MH) ithengiswa njenge-"bone-building" yokuncedisa ngokuxutywa okuphezulu xa kuthelekiswa ne-calcium.
