Neuroprotective effects of Bacopa monnieri in experimental model of dementia

Saini, Neetu, Singh, Devinder, Sandhir, Rajat·2012·Neurochemical Research

Abstract

Alzheimer disease (AD) is characterized by dementia that begins as mild short term memory deficit and culminates in total loss of cognitive and executive functions. The present study was conducted to evaluate the neuroprotective potential of Bacopa monnieri (BM), an Indian traditional medicinal plant effective against cognitive impairment, in colchicine-induced dementia. Intracerebroventricular administration of colchicine (15 μg/5 μl) induced cognitive impairment in rats as assessed by elevated plus maze. This was accompanied by a significant increase in oxidative stress in term of enhanced levels of lipid peroxidation and protein carbonyls. Concomitantly, decrease in activity of antioxidant enzymes was observed in colchicine treated animals. BM (50 mg/kg body weight) supplementation reversed memory impairment observed in the colchicine treated rats. BM administration attenuated oxidative damage, as evident by decreased LPO and protein carbonyl levels and restoration in activities of the antioxidant enzymes. The activity of membrane bound enzymes (Na(+)K(+) ATPase and AChE) was altered in colchicine treated brain regions and BM supplementation was able to restore the activity of enzymes to comparable values observed in controls. The results suggest therapeutic potential of BM in the treatment of AD associated cognitive decline.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
