In the present study, Floating Drug Delivery Beads (FDDS) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. In order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the co...
Saffron (Crocus sativus L.) protoplasts were isolated from the cells of a suspension culture or calli with a solution of Cellulase, Pectinase and Hemicellulase and embedded in Ca-alginate beads. They were cultured with or without nurse cells in MS medium supplemented with 2,4-D and 6-benzylaminopurine at 25°C. After several changes of medium, cell-clusters appeared on the surface of the Ca-algi...
Alginate beads represent a simple and highly reproducible in vitro model system for diffusion-limited bacterial growth. In this study, alginate beads were inoculated with Pseudomonas aeruginosa and followed for up to 72 h. Confocal microscopy revealed that P. aeruginosa formed dense clusters similar in size to in vivo aggregates observed ex vivo in cystic fibrosis lungs and chronic wounds. Bact...
introduction: leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. as a consequence, the use of filter technology for leukoreduction has been widely practiced .according to aabb accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...
Oral pH sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (GI) as per the pH of GI, resulting in improved patient therapeutic efficacy and compliance. The pH range of fluids in various segments of the GI tract may provide environmental stimuli for drug release. The aim of this study was to design buoyant beads c...
