This study was designed to determine whether (-)-epigallocatethin-3-O-gallate (EGCG) could reverse caffeine-induced anxiogenic-like effects in animals. In mice, EGCG antagonized the caffeine-induced reduction in both the open arm entry number and time-spent in open arm on elevated plus-maze. In addition, EGCG also antagonized the caffeine-induced reduction(More)
This experiment was designed to know whether (-)-epigallocatethin-3-O-gallate (EGCG) counteracts caffeine-induced hyperactivity, and its potential mechanisms in mice. EGCG inhibited methamphetamine-induced, cocaine-induced and caffeine-induced horizontal hyperlocomotion and rearing activity. EGCG also inhibited hyperlocomotion and rearing activity induced(More)
This experiment investigated whether (-)-epigallocatechin-3-O-gallate (EGCG) (5-20 mg/kg, p.o.) has hypnotic effects and/or enhances pentobarbital-induced sleeping behaviors and whether these effects are mediated by γ-aminobutyric acid (GABA) receptors. EGCG prolonged sleeping time induced by pentobarbital (42 mg/kg, i.p.) and reduced sleeping latency(More)
