Fig 1. Effect of khat extract and juice on escape latency during acquisition trials.

Each point across the line represents the mean ± SEM of escape latency in rats (n = 6 in each group) that received T80W, KESC (100 mg/kg, 200 mg/kg and 300 mg/kg), KESA 300 mg/kg and KHJ 2.5 mL/kg. Each group of rats was compared with rats that received T80W. KESC: khat extract subchronic, KESA: khat extract subacute, KHJ: khat juice.
