The present study demonstrates the effect of ((E)-(E)-4-(4-hydroxy-3-methoxyphenyl)-2-oxobut-3-en-1-yl 3-(4-hydroxy-3-methoxyphenyl) acrylate (CA) on spatial cognitive functions of rats with lobal cerebrovascular hypoperfusion. The bilateral common carotid arteries occlusion (2VO) surgery was performed to prepare the cerebrovascular hypoperfusion rat model. The effect of CA on spatial cognitive function was analysed using Morris water maze (MWM) test prior to and after 2VO operation. Sixty rats were randomly assigned into two groups of 30 each; long-term memory (LTM) and short-term memory (STM) groups. Both the groups were further divided into 3 subgroups: control, untreated and CA treated groups. The animals received 50 μg/kg of CA for 10 weeks of 2VO operation following which all the subgroups were tested with MWM. Both the escape latency time and total distance travelled were significantly lower for control and CA treated groups compared to untreated group revealed by working memory test. The maze test performance for control and CA treated groups was found to be improved markedly. Similarly, the results from probe memory test performance revealed significant improvement for CA treated groups compared to untreated group. Therefore, CA exhibits significant effect on the spatial cognitive preservation in rats with chronic epilepsy.
