ʻO ka hoʻohana ʻana i nā ʻili hua e mālama i ka osteoporosis

ʻIke ʻia nā ʻili hua i makemake ʻole ʻia he mea koʻikoʻi no ka hana ʻana i nā grafts iwi palekana a maikaʻi hoʻi no nā kānaka, e like me New Atlas, e ʻōlelo ana i ka puke pai Smart Materials in Medicine.

No ka hana ʻana i mea hou no ka grafting iwi palekana a maikaʻi hoʻi, ua hoʻohana nā mea noiʻi i nā ʻili hua moa, i loaʻa ākea a kūʻai ʻole.

Ua hoʻomohala nā mea noiʻi i kahi ala hou o ka hoʻoheheʻe ʻana a me ka ua e hana ai i nā ʻāpana amorphous calcium phosphate (ACP) mai nā ʻāpana hua moa, he mea nui ia no ka hana ʻana i ka iwi mineralized - ʻo ia hoʻi, paʻakikī a ikaika - a ua hoʻohana mua ʻia i pani no ka iwi. no kona mau mea.

Mea maka pono

No kāna ʻaoʻao, ʻo ka mea noiʻi alakaʻi o ka noiʻi, ʻo Kinali Ma, he polopeka ma ke Keʻena o Biomaterials ma ke Kulanui o Oslo, i ʻōlelo ʻia: "He mea waiwai maikaʻi nā ʻāpana hua no ka hana ʻana i nā mea grafting iwi no ka mea he nui nā ʻāpana o ka calcium. a me ka phosphorus. Loaʻa kekahi mau mea i pili i ka hana hou ʻana o ka iwi, e like me ka magnesium a me ka strontium, i loko o nā pūpū hua.

Ua hoʻokomo ka poʻe noiʻi i nā ʻāpana ACP i loko o kahi spheroid XNUMXD e ʻike maikaʻi i ka hana hana iwi o nā ʻāpana ma o ka launa ʻana ma waena o ka ʻiʻo iwi host a me nā mea grafting. Ua ʻike lākou ua pili maoli nā molekole ACP i loko o nā ʻōpū hua manu me nā pūnaewele e kūkulu ai i ka iwi, a me nā pōmaikaʻi ʻaʻole ia he mea ʻawaʻawa, immunocompliant, a maikaʻi hoʻi i ka hoʻoikaika ʻana i ka iwi.

ʻenehana hoʻohiki

"Ke paʻa nei kēia ʻenehana i ka ʻōlelo hoʻohiki no ka hāʻawi ʻana i ka lako palena ʻole o nā mea kanu iwi bioactive a hoʻomau i ka hoʻohaʻahaʻa ʻana i ka pollution kaiapuni," wahi a Harvard Justin Hauge, mai ke Kulanui o Oslo, Norewai a me ka mea noiʻi pili i ka noiʻi.

Manaʻo ka poʻe noiʻi e paipai kā lākou ʻike i ka noiʻi hou ʻana i ka hoʻohana ʻana i nā ʻōpala meaʻai maʻamau e like me nā biomaterials.

He mea pono ke hoomaopopoia, o ke ano maa mau o ka humuhumu iwi a puni ka honua, oia no ka hoopiha ana i na hakahaka o na iwi ma o na mea humu iwi mai na kumu like ole, e like me ka autografts mai na iwi mai o ka mea hookahi e hanaia ana, grafts mai nā iwi hāʻawi, i hōʻiliʻili ʻia i ka wā o nā kaʻina hana e like me ke pani ʻana i ka ʻūhā i sterilized no ka hoʻohana ʻana i nā grafts iwi o nā maʻi ʻē aʻe.

Hoʻolako pū ʻia nā grafts iwi mai nā iwi ola ʻole o nā holoholona e like me nā bipi a puaʻa paha, i kapa ʻia ʻo xenogeneic, i hana ʻia i nā wela kiʻekiʻe e hoʻomaʻemaʻe ʻia a ʻaʻole hōʻole ʻia e ke kino kanaka, a ʻoi aku ka maikaʻi ma mua o nā autografts a i ʻole nā ​​​​mea hāʻawi.
