PDLLA Poly(DL-lactide) CAS 51056-13-9
He polymer amorphous ʻo PDLLA me ka mahana hoʻololi aniani o 50-60 ℃ a me ka pae viscosity o 0.2-7.0dl/g. Ua ʻāpono ʻia ka mea e ka FDA a hiki ke hoʻohana ʻia ma ke ʻano he adjuvant no ka mucosa anti-adhesive ʻoki kino lapaʻau, microcapsules, microspheres a me nā implants no ka hoʻokuʻu mau ʻana, a hiki ke hoʻohana ʻia ma ke ʻano he scaffolds porous no ka ʻenekinia ʻiʻo cell culture a me ka hoʻopaʻa ʻana o ka iwi a i ʻole nā mea hoʻoponopono ʻiʻo, e like me nā sutures ʻoki kino, nā implants, ka ʻili artificial, nā kīʻaha koko artificial, a me nā retinas ophthalmic.

1. Hoʻonaninani lapaʻau: Hoʻohana nui ʻia ʻo PDLLA ma ke ʻano he mea hoʻopihapiha maka ma ke kahua o ka hoʻonaninani lapaʻau ma muli o kona biocompatibility maikaʻi loa a me ka degradability. Hiki iā ia ke hoʻoulu i ka hana ʻana o ka collagen ʻili, no laila e hoʻomaikaʻi ai i ka sagging o ka ʻili, nā wrinkles a me nā depressions.
2. Nā mea lapaʻau: Hoʻohana nui ʻia ʻo PDLLA ma ke kahua o nā mea lapaʻau, e like me nā uhi i hoʻouka ʻia i ka lāʻau lapaʻau no nā stent coronary degradable, nā sutures ʻokiʻoki, nā ʻūpā hemostatic, a pēlā aku. ʻO kona biocompatibility maikaʻi a me ka degradability e hoʻolilo i kēia mau mea lapaʻau i palekana a ʻoi aku ka maikaʻi i ka wā e hoʻohana ai.
3. ʻEnekinia ʻiʻo: He mau noi koʻikoʻi ko PDLLA ma ke kahua o ka ʻenekinia ʻiʻo, e like me ka hoʻopaʻa ʻana o ka iwi a me nā mea hoʻoponopono iwi, nā scaffolds ʻenekinia ʻiʻo, a pēlā aku. He kūpono kona ʻano porous i ka hoʻopili ʻana a me ka ulu ʻana o nā cell, no laila e paipai ana i ka hoʻoponopono a me ka hana hou ʻana o nā ʻiʻo.
4. Hoʻokuʻu ʻana i ka lāʻau lapaʻau i kāohi ʻia: Hiki ke hoʻohana ʻia ʻo PDLLA no ka hoʻokuʻu ʻana i ka lāʻau lapaʻau i kāohi ʻia a me ka hoʻopili ʻana i ka hoʻokuʻu mau ʻana. Ma ka hoʻohui ʻana me nā lāʻau lapaʻau e hana i nā ʻano dosage e like me nā microspheres a i ʻole nā microcapsules, hiki ke hoʻokō ʻia ka hoʻokuʻu lohi a me ka hana mau o nā lāʻau lapaʻau, no laila e hoʻomaikaʻi ana i ka pono a me ka palekana o nā lāʻau lapaʻau.
5. Ka hana hōʻino ʻana o PDLLA: Hōʻino mālie ʻo PDLLA, kahi e hiki ai iā ia ke hāʻawi i nā hopena therapeutic lōʻihi i nā noi lapaʻau. ʻO kāna huahana hōʻino ʻana he waikawa lactic, kahi i hoʻololi hope ʻia i loko o ke kalapona ʻokikene a me ka wai, a ʻaʻohe mea ʻawahia a ʻino ʻole i ke kino kanaka
