Abstract
In this study, we developed biodegradable poly[(d,l)-lactide-co-glycolide] nanofibrous membranes via electrospinning that provided a sustained release of BCNU. An elution method and a HPLC assay were employed to characterize the in-vitro and in-vivo release behaviors of pharmaceuticals from the electrospun membranes. The experimental results show that the biodegradable, nanofibrous membranes released high concentrations of BCNU for more than 6 weeks in the cerebral cavity of rats. Furthermore, the membranes can better conform to the geometry of the brain tissue and can cover more completely the tissue after the removal of tumors, achieving better drug transport without interfering with the normal function of the brain. Histological examination showed no obvious inflammation reactions of the brain tissues. By adopting the electrospinning technique, we will be able to manufacture biodegradable, nanofibrous membranes for the long-term deliveries of various anti- cancer drugs in the cerebral cavity, which can enhance the therapeutic efficacy of GBM treatment.
