Calcium Hydroxyapatite HAP CAS 1306-06-5
Hydroxyapatite, kapaiahydroxylapatite(HA), he ʻano mineral maoli nō ia o ka calcium apatite me ke ʻano Ca5(PO4)3(OH), akā ua kākau mau ʻia ʻo Ca10(PO4)6(OH)2 e hōʻike i ka ʻāpana ʻāpana ʻelua. ʻO ka Hydroxyapatite ka hopena hydroxyl o ka hui apatite paʻakikī. Maʻemaʻeka pauka hydroxyapatitehe keʻokeʻo. Hiki nō naʻe ke loaʻa nā ʻāpana ʻāʻī, ʻeleʻele, a ʻōmaʻomaʻo paha, e like me ka hoʻololi ʻana o ka fluorosis niho.
Hiki i ka 50% ka nui a me ka 70% o ke kaumaha o ka iwi kanaka he ʻano hydroxyapatite i hoʻololi ʻia, i kapa ʻia ʻo ka mineral iwi. Loaʻa nā kristal hydroxyapatite i loko o nā calcifications liʻiliʻi, i loko o ka pineal gland a me nā hale ʻē aʻe, i kapa ʻia ʻo corpora arenacea a i ʻole 'brain sand'.
Palapala noi
1. Aia ka Hydroxyapatite i ka iwi a me nā niho; Hana ʻia ka iwi me nā kristal HA i hoʻopili ʻia i loko o kahi matrix collagen - 65 a 70% o ka nui o ka iwi he HA. Pēlā nō ʻo HA he 70 a 80% o ka nui o ka dentin a me ka enamel i nā niho. I ka enamel, hoʻokumu ʻia ka matrix no HA e nā amelogenins a me nā enamel ma kahi o ka collagen.
ʻO ka waiho ʻana o ka hydroxylapatite i loko o nā aʻa a puni nā hui e hopena i ka maʻi calcific tendinitis.
2. Hoʻohana nui ʻia ʻo HA e hanamea humu iwia me ka hoʻoponopono niho a me ka hoʻoponopono. Hoʻopili ʻia kekahi mau mea implants, e laʻa me ka hoʻopili ʻana i ka ʻūhā, nā niho niho a me nā implants conduction iwi, me ka HA. No ka mea, ʻoi aku ka haʻahaʻa o ka hoʻoheheʻe maoli ʻana o ka hydroxyapatite in-vivo, ma kahi o 10 wt% o kēlā me kēia makahiki, ma mua o ka ulu ʻana o ka iwi iwi hou, i kona hoʻohana ʻana i mea pani iwi, ke ʻimi ʻia nei nā ala e hoʻonui ai i kona solubility rate a pela e paipai ai i ka bioactivity maikai.
3. Kūʻai ʻia ka microcrystalline hydroxyapatite (MH) ma ke ʻano he "kūkulu iwi" me ka ʻoi aku o ka absorption ma ka hoʻohālikelike ʻana me ka calcium.
