OBJECTIVE
Brain stroke is a leading cause of death without effective treatment. B. monniera, an Indian herbal medicine, exerts antioxidant activity and antistress activity by modulating the antioxidative defence system. We wanted to test if B. monniera could alleviate the ischemia induced brain injury and cognitive dysfunction in Wistar rats.
METHODS
We studied the effect of B. monniera (120mg kg(-1), 160mg kg(-1) and 240mg kg(-1) P.O.) on transient intracarotid artery (ICA) occlusion induced ischemia by testing the neurobehavioral and biochemical parameters on treated and control rats.
RESULTS
B. monniera attenuated the reduced transfer latency in ischemic rats in a step through test and showed a protective effect on ischemia induced memory impairment in the plus maze task. It also showed a marginal improvement in neurodeficit score and fore limb muscle grip strength. B. monniera reduced the infarct size in the ischemic brain. It also decreased nitrite, nitrate and lipid peroxidation and significantly improved catalase activity.
CONCLUSIONS
These observations suggest the neuroprotective and antioxidant activity of B. monniera on ischemia induced brain injury and pave the way for future investigations.
