Nui hōu i nga oko toto e whatu ana i te collagen me te polylactic waikawa fibers

wā:2020-10-20 Ngā Taunga:

I te maimoa o tūroro i te mate manawa, kua tūkino, kua āraia rānei ētahi wāhanga o te pūnaha iaia-manawa me whakahōu, ko te autologous transplantation, me ngā rawa biocompatible. Autologous transplantation e kore e taea e te manawanui te tuku i tētahi wāhanga whakahōutanga pai rawa, engari ka kore te whakahōutanga e pā ki te oranga pūnoa o te hunga e noho ana i te ora., kia aio rawa nga whakaritenga. He maha hoki nga tūroro mate manawa, kaiwhakaora te nuinga o ngā oko toto kia oti i te mahi.




Ko nga oko toto he mea hanga i te momo o te rawa me te tikanga. Aita i maoro a'e, ko te tīma o utuhia i NC, i CWRU woveled, he mea toto, he oko toa, he mea na paheko collagen me polylactic fibers.





He aha te \ o tēnei mahi toto:
(1) Collagen ngā wae i Collagen fibers e taea ai te whakanui i te adhesion pūtau tuatahi mā 10 wā. Muri i te wā o te ahurea, ko te tau o te pūtau whiwhinga me te proliferation 3.2 ko nga wa tiketike ake i taua o nga oko toto he mea hanga PLA whakaata tākaka anake, he pānga endothelialization tere.
(2) Polylactic ka taea e te whakaata tākaka waikawa te tuku i te kaha rawa me te taimautanga urutaunga tinana, me te whakatangi i te tūnga o hanganga, ko te conducive ki te huanga tere o te kaha o te toto, kia rite ki te tutuki industrialization.
(3) Na te whiria i nga oko toto e whakaatu ana i te kaha whaturuma pai (1.89±0.43 MPa) tuinga te kaha o te tautiakitanga (10.86±0.49 N), me te taumata pēhanga (3.98± 1.94% / 100 mmHg) i taupānga te iatuku arteries i raro i te pēhanga toto pūnoa (3.8± 0.3% / 100 mmHg), wmmHgatu urutau pai.







(4) Ko te kōwhai porohita patui whatu te hanga ngohengohe hei mea iatuku, ā, ka taea te whakaroha me te kirimana.




Ehara tēnei momo iaia teka i te mate kuhi, ka taea te tuku i te tautoko mō ngā oko toto e tapi ana i te wāhanga tuatahi o whakatōnga, ka taea e tipihaere te patokupu me te whenumi i te tinana. Te raruraru matua, e anga tonu ana te tīma, ko te oko hoki he urutaunga tinana pores e whakaae ana ki te toto kia rere atu.

Kua titled te mahi o te tīma "He parito iaia wanaia harnessing ko ngā āhuatanga te o kehua fibers me te mahinga koiora o Collagen filaments," I whakaputaina ki te Pūtaiao Matu me te Pūkaha: C.
