Effect of tolfenamic acid on long-term memory and learning ability in ICV-OA mice. Model group mice exhibited a significant increase in error times, compared to control mice. Tolfenamic acid attenuated the cognitive deficits in passive avoidance test. All results are expressed as the mean ± SEM. n = 10; ^##p < 0.01 versus control; **p < 0.01 versus model
