抄録
L-ornithine has recently received considerable attention as an anxiolytic-like or antifatigue agent in
both human and animal studies. However, most previous results were obtained from a single
administration of L-ornithine. Accordingly, this study was designed to clarify the effects of long-term
L-ornithine treatment on psychological stress and locomotor activity in mice using a variety of behavioral
pharmacology methods. In a stress-induced hyperthermia test, 10 days of L-ornithine treatment induced
hyperthermia elevation. Pentobarbital-induced sleep time was shortened by the treatment. However, no
significant effects were detected in the elevated plus-maze, running wheel, or forced swim tests. These
results suggest that long-term treatment with L-ornithine elevates stress sensitivity and arousal level in
mice.
