Effect of multiple ifenprodil or spermidine treatment on social recognition in rats.
We investigated the effects of multiple (21 x) ifenprodil (1.0 mg/kg, i.p.)-[IF] and spermidine (5.0 mg/kg, i.p.)-[SP] administration on short-term memory using the social recognition test in rats. The influence of a single (lx) injection of IF and SP was also established. 1x IF or SP treatment showed a statistically insignificant tendency to impair social memory task. In contrast, 21 x SP treatment facilitated short-term memory when compared with 1x SP administration. 21x IF had no affect on the memory paradigm. The results of the present study indicate that the prolonged systemic treatment of IF or SP in relatively low doses causes no impairment of short-term memory in rats.
