TJS-010, a new prescription of oriental medicine, antagonizes tetrabenazine-induced suppression of spontaneous locomotor activity in rats.
1. The authors have determined the effect of TJS-010, a new prescription of oriental medicine, on the locomotor activity in rats. 2. Tetrabenazine(TBZ) decreased the spontaneous locomotion in rats, and attenuated the contents of amines and increased their metabolism in various regions in rat brain. 3. TJS-010 inhibited the locomotor suppression induced by TBZ: however, neither amine contents nor their metabolism was not altered, which suggested that TJS-010 postsynaptically modulated the transmission or transduction. 4. Imipramine also inhibited the decrease in locomotion induced by TBZ. 5. These results suggest a possibility that TJS-010 has an antidepressive effect.
