Microspheres containing cisplatin (CDDP) embedded in poly-d,l-lactic acid (PLA) and polyethylene glycol acid (CDDP-PPMS) were developed to improve treatment of malignant effusions. In vitro studies demonstrated that CDDP was released continuously for more than 4 weeks from CDDP-PPMS without initial

A new system for the delivery bleomycin (BLM) to target lesions was established by incorporating BLM into a small cylinder of a biodegradable polylactic acid (PLA) of low molecular weight. Cross-sectional analysis of the system (BLM-PLA) showed that BLM particles were uniformly enclosed in the PLA

We observed the morphological changes in microspheres containing cisplatin (CDDP) embedded in poly-d,l,-lactic acid (PLA) and polyethylene glycol acid (CDDP-PPMS). The in vitro release of CDDP from CDDP-PPMS continued for more than four weeks. Scanning electron microscopy revealed that though the

Triptolide (TP) possesses both anti-tumour and immuno-suppressive activities. Its immuno-suppressive activity may be disadvantageous for the therapy of cancers. A novel polymeric micelle system containing TP (TP-PM) was constructed by the solvent evaporation method using methoxypolyethylene

A common phenomenon in tissue engineering is rapid tissue formation on the outer edge of the scaffold which restricts cell penetration and nutrient exchange to the scaffold centre, resulting in a necrotic core. To address this problem, we generated scaffolds with both random and anisotropic open
