Differential dose effects of central CRF and effects of CRF astressin on pig behavior.

The elevation of central corticotropin releasing factor (CRF) causes an increase in behavioral activity, including increases in overall activity and oral/nasal/facial (ONF) chewing-rooting-rubbing behaviors in the pig and similar behaviors in other species. This study detailed changes in the frequency, duration and sequences of behaviors after central administration of vehicle or porcine CRF (pCRF at 0.5, 5.

Liquid gastric emptying in the pig: effect of concentration of inhaled isoflurane.

Unlabelled: An animal model of gastric emptying may have use in the study of gastric physiology and pharmacoscintigraphy. The pig has anatomy and physiology similar to that of humans. Our aim was to develop a model of gastric emptying in the pig.
