Ukusetshenziswa kwamagobolondo amaqanda ukwelapha i-osteoporosis

Amagobolondo amaqanda angafuneki abonakala eyimpahla ebalulekile ekwenzeni ukuxhunyelelwa kwamathambo okuphephile nokuphumelelayo kubantu, ngokusho kwe-New Atlas, icaphuna iphephabhuku elithi Smart Materials in Medicine.

Ukuze udale into entsha yokufakwa kwamathambo okuphephile futhi okuphumelelayo, abacwaningi baphendukela kumagobolondo enkukhu enkukhu, atholakala kabanzi futhi angabizi.

Abacwaningi sebesungule indlela entsha yokuhlakazeka kanye nemvula ukuze bakhe izinhlayiya ze-amorphous calcium phosphate (ACP) emagobolondweni enkukhu, ezibalulekile ekwakhekeni kwamathambo anamaminerali - okungukuthi, aqinile futhi aqinile - futhi ayekade esetshenziswa esikhundleni sethambo. ngenxa yezingxenye zayo.

Perfect impahla eluhlaza

Ngakolunye uhlangothi, umcwaningi oholayo walolu cwaningo, uKinali Ma, uprofesa eMnyangweni Wezinto Eziphilayo eNyuvesi yase-Oslo, uthe: “Amagobolondo amaqanda ayimpahla eluhlaza efanelekile yokwenza izinto zokuxhunyelelwa amathambo ngoba aqukethe izakhi eziningi ze-calcium. kanye ne-phosphorus. Ezinye izakhi zokulandelela ezihlobene nokuvuselelwa kwamathambo, njenge-magnesium ne-strontium, nazo zitholakala kumagobolondo amaqanda.”

Abacwaningi bashumeke izinhlayiya ze-ACP ku-XNUMXD spheroid ukuze bahlaziye kangcono umsebenzi wokwakheka kwamathambo ezinhlayiya ngokusebenzisana phakathi kwezicubu zamathambo abambayo nezinto zokuxhunyelelwa. Bathole ukuthi ama-molecule e-ACP kumagobolondo amaqanda e-vitro empeleni asebenzisana namaseli akha ithambo, kanye nezinzuzo zokuthi ayengenabo ubuthi, awahambisani namasosha omzimba, futhi esebenza ngempumelelo ekukhuthazeni ukuvuselelwa kwamathambo.

Ubuchwepheshe obuthembisayo

"Lobu buchwepheshe bunesithembiso sokuhlinzeka ngokuhlinzekwa okungenamkhawulo kwezinto zokuxhunyelelwa kwe-bioactive neziqhubekayo ngenkathi kunciphisa ukungcoliswa kwemvelo," kusho u-Harvard Justin Hauge, wase-University of Oslo, eNorway kanye nomcwaningi ohambisanayo ocwaningweni.

Abacwaningi banethemba lokuthi lokho abakutholile kuzokhuthaza ucwaningo olwengeziwe mayelana nokusetshenziswa kwemfucuza yokudla ejwayelekile njengama-biomaterials.

Kuyaphawuleka ukuthi indlela evamile yokuxhunyelelwa kwamathambo emhlabeni wonke iwukugcwalisa izikhala noma izikhala emathanjeni ngokuxhunyelelwa amathambo emithonjeni ehlukahlukene, kuhlanganise nokugxunyekwa emathanjeni omuntu ofanayo ohlinzwayo, noma kusukela. ama-graft avela emathanjeni abanikeli, aqoqwa ngesikhathi sokuhlinzwa okufana nokushintshwa kwe-hip afakwa inzalo ukuze asetshenziswe kwezinye iziguli ukuxhunyelelwa amathambo.

Ukuxhunyelelwa kwamathambo nakho kuhlinzekwa kusuka emathanjeni angaphili ezilwane njengezinkomo noma izingulube, ezibizwa ngokuthi i-xenogeneic, ezicutshungulwa emazingeni okushisa aphezulu ukuze zibulale inzalo futhi zinganqatshwa ngumzimba womuntu, futhi ngokuvamile zisezingeni eliphansi kune-autografts noma abanikelayo.
