Ukusetyenziswa kwamaqokobhe amaqanda ukunyanga i-osteoporosis

Amagobolondo eqanda angafunekiyo abonakala eyinto ebalulekileyo yokwenza i-grafts yamathambo ekhuselekileyo nesebenzayo kubantu, ngokutsho kweNew Atlas, ecaphula iphephancwadi i-Smart Materials in Medicine.

Ukuze udale izinto ezintsha zokufakelwa kwamathambo okukhuselekileyo kunye nokusebenzayo, abaphandi babhenela kwiinkukhu zenkukhu, ezifumaneka ngokubanzi kwaye zingabizi.

Abaphandi baye baqulunqa indlela entsha yokuchithwa kunye nemvula ukwenza i-amorphous calcium phosphate (ACP) yamaqhekeza avela kumaqanda amaqanda enkukhu, ayimfuneko ekubunjweni kwethambo leminerali - oko kukuthi, lukhuni kwaye lomeleleyo - kwaye yayikade isetyenziswe endaweni yethambo. ngenxa yamacandelo ayo.

Imathiriyeli ekrwada egqibeleleyo

Kwicala lakhe, umphandi okhokelayo wolu phando, uKinali Ma, unjingalwazi kwiSebe leBiomaterials kwiYunivesithi yaseOslo, uthe: “Amaqokobhe angamaqanda ayinto efanelekileyo yokwenza izinto ezixutywa ngamathambo kuba ziqulethe izinto ezininzi zecalcium. kunye nephosphorus. Ezinye izinto ezinxulumene nokuvuselelwa kwamathambo, njengemagnesium kunye nestrontium, zikwafumaneka kumaqokobhe amaqanda.

Abaphandi bafakela iinqununu ze-ACP kwi-spheroid ye-XNUMXD ukuhlalutya ngcono umsebenzi wokwakheka kwamathambo weengqungquthela ngokusebenzisa intsebenziswano phakathi kwezicubu zethambo ezibambayo kunye nezinto zokuxhunyelelwa. Bafumanise ukuba iimolekyuli ze-ACP kumaqokobhe amaqanda e-vitro ngokwenene zinxibelelana neeseli ezakha ithambo, kunye neengenelo zokuba zazingeyotyhefu, zinganyangeki, kwaye zisebenza kakuhle ekukhuthazeni ukuvuselelwa kwamathambo.

Iteknoloji ethembisayo

"Obu buchwepheshe bubambe isithembiso sokubonelela ngokubonelelwa okungenamkhawulo kwezixhobo zokuxutywa kwe-bioactive kunye nezizinzileyo ngelixa kunciphisa ukungcoliseka kwendalo," kusho uHarvard Justin Hauge, weYunivesithi yase-Oslo, eNorway kunye nomphandi ohambelanayo kwisifundo.

Abaphandi banethemba lokuba iziphumo zabo ziya kukhuthaza uphando olongezelelweyo ekusebenziseni inkunkuma yokutya eqhelekileyo njengezinto eziphilayo.

Kuyaphawuleka ukuba indlela eqhelekileyo yokufakelwa kwamathambo emhlabeni jikelele kukugcwalisa i-voids okanye izithuba emathanjeni ngokusebenzisa izinto ezixutywe ngamathambo ezivela kwimithombo eyahlukeneyo, kubandakanywa i-autografts evela kumathambo omntu ofanayo owenziweyo, okanye ukusuka. uxhulumaniso olusuka kumathambo abanikeli, aqokelelwa ngexesha leenkqubo zoTyando ezifana nokutshintshwa kwenyonga evalwa inzala ukuze isetyenziswe kwezinye izigulana’ amathambo.

Ukufakwa kwamathambo kukwabonelelwa ukusuka kumathambo angaphiliyo ezilwanyana ezifana neenkomo okanye iihagu, ezibizwa ngokuba yi-xenogeneic, ezicutshungulwa kumaqondo obushushu aphezulu ukuze zibulale iintsholongwane kwaye zingakhatywa ngumzimba womntu, kwaye zihlala zikumgangatho ophantsi kune-autografts okanye abaxhasi.
