Abstract
The influence of cilostazol on learning and memory, and cyclin D1 expression in the cerebral cortex of rats with chronic cerebral ischemia were investigated. A chronic cerebral ischemia model was established using the permanent bilateral common carotid artery occlusion method (2VO), learning and memory capacity was detected using the Morris water maze, and expression changes in apoptosis regulating gene cyclin D1 were tested by RT-PCR. Results of the Morris water maze indicated that significant extensions were found in the escape latent period and swimming path of rats in the ischemia group (2VO group), learning and memory results in the cilostazol group was obviously superior compared to the 2VO group (P<0.05), and the expression of cyclin D1 was observed to increase in both the ischemia and cilostazol intervention groups at the 9th week of ischemia. A significant difference was observed, compared with the sham operation group (P<0.05), the expression level decreased in the ischemia group compared with the cilostazol group, and a significant difference was identified compared with the ischemia group (P<0.05). Cilostazol can reduce nerve function impairment and improve learning and memory functions by affecting changes in apoptosis regulating genes.
