| Abstract | Background: Silymarin, an extract from seeds of milk thistle (Silybum marianum), is known to have hepato-protective, anticarcinogenic, antioxidant and estrogenic effects. Objective: The aim of the present study was to test the effect of silymarin on passive avoidance learning in rats. Methods: This was an experimental study carried on Wistar rats in Arak University, Iran. The animals were provided with silymarin (from day 7 of gestational age to 4 weeks after birth) at 2 doses of 180 mg/kg in the experimental group 1 (Exp1) and 90mg/kg in the experimental group 2 (Exp2) while the sham group received saline and the control group with regular food and water. The memory retention and duration of step-through latency in male offsprings was determined by passive avoidance apparatus. Neuronal density in hippocampus was established by histopathological methods. Memory and learning indices were investigated by analysis of variance (ANOVA) and a p value less than 0.05 was considered as significant. Findings: Both experimental groups showed significantly longer step-through latency compared to control group (p | en |
