| Outline of Final Research Achievements |
We examined whether the long-term and low-concentrated lithium administration decrease the impulsivity of mice.In Open field test, the significant difference was not seen about anxiety and moving distance between the lithium administrated group and the control group.In a resident-intruder test, extension of the first attack latency was seen in the lithium administrated group(50 mg/L) in comparison with the control group.In the lower lithium administrated mice group, there are equilateral association with lithium concentration for the first battle latency, and negative association with lithium concentration at battle time.In this experience, the long-term and low-concentration lithium administration to mice from younger period after birth seemed to decrease the impulsivity. This result supports that in human, the long-term and low-concentration lithium administration may decrease the impulsivity. And as a result of this, the number or the risk of suicide decreases.
