title: Effect of intracerebroventricular administration of soybean lecithin transphosphatidylated phosphatidylserine on scopolamine-induced amnesic mice.
abstract: The effect of intracerebroventricularly administered soybean lecithin transphosphatidylated phosphatidylserine (SB-tPS) on memory impairment was evaluated by a passive avoidance task. SB-tPS significantly prolonged the step-through latency induced by scopolamine treatment as in our previous report where SB-tPS was orally administered. The same doses of soybean phosphatidylcholine were ineffective. This result indicates that SB-tPS can act on the brain without any peripheral modification.
