In commercial corn production, small seed size is discarded from the seed lot and used as the animal feed, resulting in less profit to the seed industry. Therefore, the objective of this research was to increase seed size by seed pelleting methods. In this study, the types of filler pelleting materials and ratio of binder materials were investigated. The experiment was conducted at Seed Quality Test Laboratory of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Small seed size of hybrid corn that retained on grade 14/64” diameter sieve perforations were pelleted with seven different types and ratios of fillers (vermiculite, bentonite, pumice, calcium sulphate, calcium carbonate, charcoal and coconut) with four different types of binders...

Floating ability and drug release evaluation of gastroretentive microparticles system containing metronidazole obtained by spray drying BJPS
Nohemann,Laís; Almeida,Marina Penteado de; Ferrari,Priscileila Colerato.
Abstract Gastroretentive floating microparticles were developed and evaluated for the controlled metronidazole delivery for treatment of gastric disease. Floating microparticles, varying in proportions of chitosan and hydroxypropyl methylcellulose or ethylcellulose, were obtained by spray drying. Floating microparticles were characterized by physicochemical and in vitro studies, according to their floating ability and drug delivery. Microparticles presented mean diameter from 1.05 to 2.20 µm. The infrared spectroscopy confirmed the drug encapsulation and showed no chemical linkage between microparticles components. X-ray diffraction showed changes in the drug`s solid state, from crystalline to amorphous, indicating partial drug encapsulation, due to the...
