bacopa/scopolamine

In the present communication, we have investigated effects of the CDRI-08, a well characterized extract of Bacopa monnieri, on expression of the GluN2B subunit of NMDAR in various brain regions of the scopolamine-induced amnesic mice. Our behavioral data reveal that scopolamine-treated amnesic mice

OBJECTIVE Alzheimer's disease (AD) is the most common cause of dementia yet treatment options are extremely limited. The disease is associated with cognitive impairment as well as structural irregularities, accumulation of plaques and neurofibrillary tangles, diminished levels of acetylcholine,

Three new saponins, bacopasides IX-XI (1- 3), together with their known analogues bacopaside I (4), bacopaside II (5), bacopasaponsin C (6), and bacopasaponsin D (7), were isolated from the whole plant of Bacopa monniera. Compounds 3, 4, and 6 showed nootropic activity when tested in the Morris

Scopolamine, an anticholinergic, is an attractive amnesic agent for discerning the action of candidate antiamnesic drugs. Bacopa monniera Linn (Syn. Brahmi) is one such antiamnesic agent that is frequently used in the ancient Indian medical system. We have earlier reported the reversal of

Scopolamine is a competitive antagonist of muscarinic acetylcholine receptors, and thus classified as an anti-muscarinic and anti-cholinergic drug. PC12 cell lines possess muscarinic receptors and mimic the neuronal cells. These cells were treated with different concentrations of scopolamine for 24

Brahmi vati (BV) is an Ayurvedic polyherbal formulation used since ancient times and has been prescribed in seizures associated with schizophrenia and related memory loss by Ayurvedic practitioners in India. The aim of the study was to investigate these claims by evaluation of anticonvulsant,

Preclinical studies on animal models have discerned the antiamnesic and memory-enhancing potential of Bacopa monniera (Brahmi) crude extract and standardized extracts. These studies primarily focus on behavioral consequences. However, lack of information on molecular underpinnings has limited the

Cognition-enhancing activity of Bacopa monniera extract (BME) was evaluated against scopolamine-induced amnesic rats by novel object recognition test (NOR), elevated plus maze (EPM) and Morris water maze (MWM) tests. Scopolamine (2 mg/kg body wt, i.p.) was used to induce amnesia in rats. Piracetam

Scopolamine, an anticholinergic drug, is reported to produce amnesia by interference of long term potentiation and has been used for discerning the efficacy of various antiamnesic drugs. The intoxication with anticholinergics and benzodiazepines tend to produce neurodegeneration which cause memory

Bacopa monnieri (L.) Wettst. (BM) has been traditionally used in Ayurveda for improving memory and cognitive deficits which is also evidenced through experimental and clinical studies. The neuropharmacological properties of BM are attributed to "bacosides", a complex mixture of saponin

The effects of ethanolic extracts of whole plants of Bacopa monnieri (BME), Evolvulus alsinoides (EAE), Tinospora cordifolia (TCE) and their combinations in equal proportion [CEP-1 (BME+EAE), CEP-2 (BME+TCE), CEP-3 (EAE+TCE) and CEP-4 (BME+EAE+TCE)] were tested in amnesic rats using Radial arm maze

This study investigated the effects of alcoholic extract of Bacopa monnieri (L.) Wettst. (BM) on cognitive deficits using olfactory bulbectomized (OBX) mice and the underlying molecular mechanisms of its action. OBX mice were treated daily with BM (50 mg/kg, p.o.) or a reference drug, tacrine (2.5

OBJECTIVE The aim was to design an alternative solvent-free extraction method using the hydrophilic lipid Gelucire (polyethylene glycol glycerides) for herbal extraction and to confirm the efficacy of extraction using biological screening. METHODS Bacopa monniera Linn. (BM) was selected for the

BACKGROUND Amnesia is characterized by loss of memory that could result from abnormal neuro-chemical homeostasis, genetic predisposition or drug abuse. We earlier reported that B. monniera attenuates diazepam, scopolamine and L-NNA induced amnesia and wanted to test if SOD levels were affected by

N-methyl-D-aspartate (NMDA) receptor and nitricoxide syntheses are the emerging target sites for development of novel drug molecules because their modulation affects the long term potentiation (LTP) process. NMDA receptor antagonists and nitric oxide synthase inhibitors induce amnesia in animals and
