Bioglass bone grafts inogona kukurumidza kuve yakajairwa kugadzirisa patsva kwemapfupa akatyoka. Basa rechikwata cheSpanish chekutsvagisa rinogadzira nzira yemhando yegirazi inobatsira kuporesa matyoka, uye yobva yanyungudika zvakachengeteka kana basa raro raitwa.

Bioglass, rudzi rwegirazi rinoshanda rinosungirira kumapfupa emapfupa, ragara riri chinangwa chinovimbisa chetsvakiridzo yekuvandudza mapfupa. Mabhonzo ane hutano anogona kuzvirapa mushure mekukuvadzwa kushoma, asi kutsemuka kukuru kana chirwere chekuderera senge osteoporosis inodzikamisa kugona kwavo kugadzirisa. Zvisungo zvakaita sezvipikiri zvesimbi zvinogona kubata matsemu pamwe chete kwenguva yakakwana kuti apore, asi zvinoda kuvhiyiwa kaviri: imwe yekuiisa uye yechipiri kuibvisa mushure mekugadzirisa bhonzo. Bioglass mapfupa ekubatanidza, ane makemikari hunhu anokurudzira kukura kwesero, yaizobvisa kudiwa kwekuvhiyiwa kwechipiri nekuti inonyungudika sezvo mapfupa emapfupa anokura achidzoka.

Zvisinei, bioglass bone regeneration yakaderedzwa nehuwandu hwezvinhu. Mishonga yeBioglass haifanire kunge yakasimba zvakakwana kutsigira bhonzo; dzinodawo kuve biocompatible, kusakonzeresa kukuvadza kumasero ari mumuviri wemunhu, uye biodegradable, inokwanisa kunyungudika kuita nontoxic makomisheni nekufamba kwenguva. Mazhinji aripo bioactive girazi makomisheni anotadza bvunzo yebiocompatibility, achigadzira zvinogona kukuvadza byproducts izvo zvinomisa kushandiswa kwavo kwakachengeteka semabhonzo ekubatanidza mumushonga.

Jose Ramon Sarasua naAitor Larrañaga, vaongorori mudhipatimendi reinjiniya yeUPV/EHU-Yunivhesiti yeBasque Country muSpain, vanga vachidzidza dambudziko iri. Mune bepa idzva rakabudiswa mupepanhau rePolymer Degradation uye Kugadzikana, vanopa nzira itsva yekugadzira iyo inogona kuita kuti zvinhu zvigadzikane zvakakwana kuti zvishande se bioglass bone graft pasina kusatarisirwa kwakashata kwakashata.

Bioglass inoitirwa kusimbisa chimwe chinhu mune biological implants, kazhinji biodegradable polymer inokurudzira kukura kwebhonzo asi yakapfava zvakanyanya kutsigira mapfupa akatyoka ari ega. Iyo bioglass/biodegradable polymer compound yakasimba kupfuura iyo polymer yega, asi kemikari inoitika inoitika panguva yekubatanidza zvinhu izvo zvinoita kuti komisheni yekupedzisira iburitse zvinogona kukuvadza byproducts nekufamba kwenguva.

Mukutsvagisa kwavo, Sarasua naLarrañaga vanopa zano rekuwedzera kugadzikana kweiyo bioglass/biodegradable polymer compound nekuchinja kwemakemikari pamusoro pebioglass nekurapa kweplasma. Plasma, inoonekwa seimwe yenzvimbo ina dzinokosha dzezvinhu, ine zvinhu zvakafanana kune magasi uye zvinwiwa. Mumamiriro ezvinhu akadzorwa, plasma inogona kushandura kemikari yepasi yemakomponi pasina kushandura hunhu hwavo. Kurapwa kweplasma kunonyanya kukosha muhunyanzvi hwekurapa, kusadzikamisa nzvimbo dzebioactive zvinhu kuti zvisakonzerese kusawirirana kana zvakadyarwa mumuviri, asi zvichivabvumira kuchengetedza zvinhu zvavanoda.

Sarasua naLarrañaga vanotarisira kuti plasma-yakagadzirwa bioglass ichave neaya ekudzivirira ayo anodzivirira kuita kusingadiwe nemapolymers anodeka. Iyo inokonzeresa bioglass / biodegradable polymer ichave yakanyanya kuenderana senge pfupa graft, iine chinangwa chekusimbisa uye kukura-kusimudzira mabasa akasimba.

Kana kurapwa kweplasma kuchishanda pamwe chete mukuita sezvakunoita mudzidziso, ichave budiriro huru yekuvandudzwa kwesero ne bioglass bone grafts.

Nekuda kwetsvakiridzo yavo, "aya macomposites ane biodegradable polymer base ndevamiriri vane ramangwana rakajeka mukugadzirisa mapfupa akatyoka kana kuvandudza kuremara kwemapfupa," akadaro Sarasua mukutaura kwevatori venhau.
