Assessment of the influence of cilostazol on learning-memory and motor co-ordination by rodent models

Abstract

Dementia is a set of symptoms that include worsening of the routine of cognitive tasks, learning, reproducibility, and gait disturbances beyond typical aging. Activated c AMP can produce anti-apoptosis activity, neuroprotective activity, motor improvement, and cognitive enhancement activity. Cilostazol can increase c AMP levels, so this study aimed to evaluate the influence of cilostazol on learning-memory and motor coordination by rodent models. The rats were divided into 5 and 6 groups with 6 rats in each to test the hypothesis respectively. Before MES seizure induction the rats were trained for conditioned avoidance response for 14 days and the best one was selected for assessment. The performance of intervention treated groups to determine the memory retention effect was measured by applying a fixed number of shocks. The intervention treated groups were tested for motor coordination performance by rotarod test (4-45 RPM accelerating speed for 5 min) after 30 and 60 min. The latency time of each rat falls off from the rod for the first time was noted. The results were presented as Mean ± SD, tested by ordinary two way ANOVA followed by Tukey's multiple comparisons test. Cilostazol 100 mg/kg p.o demonstrated a significant memory enhancement activity in the conditioned avoidance response technique. Cilostazol 20mg/kg i.p alone and along with diazepam 2 mg/kg demonstrated a significant motor coordination performance in both sessions. The present study concludes that cilostazol has improved the learning & memory and motor coordination performances.
