Abstract:
AIM To investigate the tissue distribution of brucine-loaded solid lipid nanoparticles in mice in vivo.METHODS Mice were intravenously injected with suspension of prepared brucine-loaded solid lipid nanoparticles and marked by fluorescein isothiocyanate (FITC).The in vivo tissue distribution of nanoparticles was analyzed by having the brucine contents in various tissues (heart,liver,spleen,lung,kidney and bone) determined by HPLC,after which fluorescence confocal laser endomicroscopy was used for further detection.RESULTS Brucine had its the highest (1.64) relative intake efficiency (Re) in mice liver,and the nanoparticles shared all over one value of targeting efficiencies (Te) in various tissues,manifesting a much stronger selectivity to liver than that of brucine solution.With the extension of time,the FITC-narked nanoparticles displayed a rich extracellular to intracellular distribution indicating a positive correlation.CONCLUSION Brucine's increased distribution in the liver tissue of mice due to its solid lipid nanoparticle form shows obvious for liver targeting.
