To control the release rate and mask the bitter taste, cetirizine dihydrochloride (CedH) was entrapped within chitosan nanoparticles (CS-NPs) using an ionotropic gelation process, followed by microencapsulation to produce CS matrix microparticles using a spray-drying method. The aqueous colloidal CS-NPs dispersions with a drug encapsulation efficiency (EE)(More)
To expand the salt-tolerant gene resources of peanut, we conducted in vitro mutagenesis with pingyangmycin (PYM) as the mutagen and directed screening with medium containing NaCl. After embryonic leaflets from mature peanut seeds (variety Huayu 22) were cultured on somatic embryogenesis-induction medium containing 4 mg/L PYM for 4 weeks, the surviving(More)
Scopolamine hydrobromide (SH)-loaded microparticles were prepared from a colloidal fluid containing ionotropic-gelated chitosan nanoparticles using a spray-drying method. The spray-dried microparticles were then formulated into orally disintegrating tablets (ODTs) using a wet granulation tablet formation process. A drug entrapment efficiency of about 90%(More)
