Calcium Hydroxyapatite HAP CAS 1306-06-5
Hydroxyapatite, sidoo kale loo yaqaanhydroxylapatite(HA), waa macdan si dabiici ah u dhacda oo ah calcium apatite oo leh qaacidada Ca5(PO4)3(OH), laakin waxaa badanaa loo qoraa Ca10(PO4)6(OH)2 si loo tilmaamo in unugga crystal ka kooban yahay laba qaybood. Hydroxyapatite waa xubinta ugu dambeysa ee hydroxyl ee kooxda apatite adag. daahirbudada hydroxyapatitewaa cadaan. Apatites-ka dabiiciga ah, si kastaba ha ahaatee, waxay sidoo kale yeelan karaan midabyo bunni, huruud ah, ama cagaar ah, oo la barbar dhigi kara midabada fluorosis ee ilkaha.
Ilaa 50% mugga iyo 70% miisaanka lafaha bini'aadamka waa nooc la bedelay oo hydroxyapatite ah, oo loo yaqaan macdanta lafaha. Kiristaalo Hydroxyapatite sidoo kale waxaa laga helaa calcifications yar yar, gudaha qanjidhada pineal iyo dhismayaasha kale, loo yaqaan corpora arenacea ama 'ciid maskaxda'.
Codsiga
1. Hydroxyapatite waxay ku jirtaa lafaha iyo ilkaha; lafta waxa ay ugu horrayn ka samaysan tahay kiristaalo HA oo ku dhex jira matrix collagen -- 65 ilaa 70% tirada lafaha waa HA. Sidoo kale HA waa 70 ilaa 80% tirada dentin iyo dhaldhalaalka ilkaha. Dhaldhalaalka, jaantuska HA waxaa sameeyay amelogenins iyo enamelins halkii ay ka ahaan lahaayeen kolajka.
Kaydinta Hydroxylapatite ee seedaha ku wareegsan kala-goysyada waxay keentaa xaalad caafimaad oo ah tendinitis calcific.
2. HA si sii kordheysa ayaa loo isticmaalaa in lagu sameeyoqalabka lagu tallaalo lafahaiyo sidoo kale saabuunta ilkaha iyo dayactirka. Qaar ka mid ah maqaar-galaha, tusaale beddelka misigta, tallaalka ilkaha iyo kuwa lafaha lafaha, ayaa lagu dahaadhay HA. Maaddaama heerka kala dirida asalka ah ee hydroxyapatite in-vivo, ku dhawaad 10 wt% sanadkii, aad ayuu uga hooseeyaa heerka korriinka unugyada lafaha cusub ee la sameeyay, iyada oo loo isticmaalo sida walxaha beddelka lafaha, habab ayaa la raadinayaa si kor loogu qaado heerka milanka iyo sidaas awgeed waxay kor u qaadaysaa firfircoonida noole ee wanaagsan.
3. Microcrystalline hydroxyapatite (MH) waxa loo suuq geeyaa sidii "lafo-dhisme" dheeri ah oo leh nuugista sare marka loo eego kaalshiyamka.
