Mazai asingadikanwi anoita sechinhu chakakosha pakugadzira mapfupa akachengeteka uye anobudirira kune vanhu, maererano neNew Atlas, ichitaura nezvemagazini Smart Materials in Medicine.

Kuti vagadzire chinhu chitsva chekuchengetedza uye chinoshanda chepfupa, vatsvakurudzi vakashandura mazai ehuku, ayo anowanikwa uye asingadhuri.

Vatsvakurudzi vakagadzira nzira itsva yekunyungudutswa uye kunaya kwemvura kuti vagadzire amorphous calcium phosphate (ACP) zvidimbu zvemazai ehuku, izvo zvakakosha pakuumbwa kwemamineralized bone - kureva, yakaoma uye yakasimba - uye yakanga yamboshandiswa sechinzvimbo chepfupa. nokuda kwezvikamu zvayo.

Yakakwana mbishi zvinhu

Nekuda kwake, muongorori anotungamira wechidzidzo ichi, Kinali Ma, purofesa paDhipatimendi reBiomaterials paYunivhesiti yeOslo, akati: “Mazai ndiwo akanakira kugadzirwa kwemapfupa ekubatanidza zvinhu nekuti ane zvakawanda zvinoumba calcium. uye phosphorus. Zvimwe zvinhu zvine chekuita nekuvandudzwa kwemapfupa, senge magnesium nestrontium, zvinowanikwawo mumagoko emazai. "

Vatsvakurudzi vakaisa zvikamu zveACP mu XNUMXD spheroid kuti vaongorore zviri nani basa rekugadzira bhonzo rezvikamu kuburikidza nekubatana pakati pemabhonzo emapfupa uye zvinhu zvekubatanidza. Vakaona kuti ma ACP mamorekuru mumashells in vitro ainyatso dyidzana nemaseru anovaka bhonzo, pamwe nemabhenefiti ayo aive asiri muchetura, asingawirirane, uye anoshanda mukusimudzira kuvandudzwa kwemapfupa.
