Abstract :
As respect to this thatGinkgo biloba is one of the most popular herbs which is used to treat amnesia.In this research we investigate the effects of Ginkgo Biloba on passive avoidance learning via measurement STL(Step Through Latency) in male wistar rat.The powder of extractGinkgo biloba buying from Drug Ahura Company in Iran with no addictive materials and testing on male wistar rat. We use the dosages 40, 65, 90 mg/kg and the dosage 65 mg/kg is as effective dosage. The unit that we use in this test is shuttle box.The unit of Passive Avoidance Learning is shuttle box. The base of this type of learning was the relation between conditioned stimulus (dark) and unconditioned stimulus (electrical shocks). The dosage 65 mg/kg has the most effect and select as effective dosage (p andlt; 0.05) that cause increase in STL(second) and corticosterone (mg/dl).
