Abstract
Hipertermia magnetikoa minbiziaren aurkako terapia berritzaile bat da. Tumorean estrategikoki jarritako nanopartikulek kanpotik aplikatutako irrati maiztasun eremu magnetiko batetik energia xurgatzen dute eta bero-iturri moduan jokatzen dute, minbizi zelulak hiltzen dituztelarik tenperatura igoeraren ondorioz. Gaur egun ikerketa ugari egiten ari dira hipertermia magnetikoa terapia alternatibo moduan aplikatzeko. Gure ikerketa taldearen helburua hipertermia magnetikoa kolon- ondesteko gibel metastasia tratatzeko eraginkorra den ikustea da. Horretarako laborategiko arratoiekin “in vivo" saiakerak egin dira Fe3O4-PMAO-RGD nanopartikulak erabiliz eta 606kHz-ko maiztasuna eta 14kA.m-1-ko intentsitatea duen eremua aplikatuz.
Magnetic hyperthermia is a cancer thermotherapy where magnetic nanoparticles placed inside or near the tumor act as heat sources activated by an externally applied magnetic field. These nanoparticles increase the temperature of the tumor cells causing the destruction of the tumor. Nowadays magnetic hyperthermia is being explored as an alternative therapy in order to treat some cancers. The aim of our work is to prove the effectiveness of the hyperthermia in “in vivo" assay in laboratory rats to treat colorectal cancer with liver metastases.
