The single or repeated administration of pentylenetetrazole (PTZ) can induce seizure in rat. This study evaluates the neuroprotective effect of lithium chloride (LiCl) on PTZ-induced working and spatial memory deficit. Materials and Methods: To induce the PTZ-kindling model, repeated doses of PTZ (40mg/kg/BW/ip) were injected for 5 consecutive days. After observing five stages of seizure, the PTZ+Li20, PTZ+Li40 and PTZ+Li80 groups received 20, 40 and 80 mg/kg/BW of LiCl, respectively and the PTZ+Saline group, received Saline for 14 days. The Morris water maze (MWM) and Y maze tests were conducted in order to investigate the spatial and working memory. Results: Compared to Control group, the PTZ+Saline group showed a decrease in alteration behavior in Y maze and an increase in latency time and distance to hidden platform in MWM. LiCl-treated rats, especially in the lowest dose, showed a significant higher alteration behavior in Y maze and the lower latency time and distance to hidden platform in MWM than the PTZ+Saline group. Conclusion: The neuroprotective effects of LiCl can ameliorate the spatial and working memory impairment in a PTZ-kindling model. M3 ER -
