Abstract:
OBJECTIVE: To study the effect of breviscapine on memory and antioxidation ability in A(342-induced Alzheimer's disease (AD) rat model. METHODS: AD rat model was established by intracerebroventricular injection of A (342. Besides, sham-operated mice served as control group. The learning and memory ability was determined by Morris water maze test. The activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) and the content of Malondialdehyde (MDA) in brain tissue were measured with spectrophotometer. RESULTS: Compared with control group, AD model significantly prolonged the latency of searching the hidden platform in directional swimming test, and decreased time spent in swimming in the target quadrant in probe test. Breviscapine dose-dependently shortened the latency of searching the hidden platform in directional swimming test, and increased the time spent swimming in the target quadrant in probe test. The activities of GSH-Px and SOD were decreased, and the MDA content was increased in AD model rats. In breviscapine treatment groups, the activities of GSH-Px and SOD heightened and MDA content decreased, and there was significant difference compared with AD model group. CONCLUSION: Breviscapine can dose-dependently ameliorate the impaired learning and memory function of AD model rats and improve antioxidation ability.
