The rate of percutaneous absorption of piroxicam in rabbit skin preparations mea-sured was 14.07±3.1lμg/cm~2/h and that in the given transdermal delivery system was 12.43±4.21μg/cm~2/h. The method described is a rapid and laboursaving technique for monitoring the penetration of some drugs across excised skin.
This experiment is- carried by using the long bone shafts of ox prepared for the heterogenous decalcified bone matrix(HDBM) and adding the delivery system (CaCl2 or CaSO4+Na2HPO4+KH2PO4), implanted into the 1.5 cm defect of the rabbit ulna.
Objective To develop the plastic nano-hydroxyapatite (nano-HA)/poly (3-hydroxybutyrate-hydroxyvalerate) - polyethylene glycol(PHBV-PEG) gentamicin (GM) drug delivery system(DDS)(nano-HA/PHBV-PEG-GM-DDS) for treating osteomyelitis and find its releasing character in vivo.
Method: The HPLC system consisted of Shimadzu Class VP5. 0 multi - solvent delivery system:Shimadzu LC 10A TVP auto sampler: Shimadzu LC 10A TVP photodiode array de-tector(PDA) ,Shimadzu temperature control module. Column:Shimadzu VP - ODS 4 um,150 mm×4. 5 mm. Solvent :isocratic with methanol,acetonitrile and water(25: 5:70).
The preparation methods of the hollow microspheres,such as spary drying method,templating mehtod,emulsion polymerization,and its application in drug delivery system,catalyzer and building materials fields are reviewed.
The gas delivery system utilizes a porous diaphragm from a carbon-carbon composite material whose pore size is comparable with the Debye radius of the electrons of plasma formed in a discharge channel.
The regulation of hFIX cDNA expression in myoblasts was discussed and it was strongly suggested that a myoblast-mediated gene delivery system had the potential to be optimized as a safe and effective therapeutic modality for hemophilia B.
