| Outline of Final Research Achievements |
Dysphagia is a major complication of stroke and often leads to lethal aspiration pneumonia in the patients. In the present study, we investigated the effects of FAD012, a synthetic novel derivate of ferulic acid (FA), against the swallowing dysfunction induced by bilateral common carotid artery occlusion (2VO) in male Sprague-Dawley rats. Rats were continuously treated with FAD012 (3 or 10 mg/kg daily, p.o.) from one week before 2VO. Chronic pretreatment with FAD012 but not FA maintained the cerebral blood flow (CBF) in 2VO rats. 2VO rats had an attenuated swallowing reflux evoked by injection of stimulating solution (50 μL of water or citric acid) into the pharyngolaryngeal region. FAD012 dose-dependently improved the swallowing reflux, and these effects were more potent than FA. These results suggest that FAD012 ameliorates the swallowing dysfunction in part via improvement of CBF in 2VO rats.
