Lisinopril and fosinopril were compared on scopolamine-induced learning and memory deficits in rats. A total of eighty-four male Wistar rats were divided into seven groups. Group I received 2% gum acacia orally for 4 weeks, group II received normal saline, and group III received scopolamine (2 mg/kg/ip) as single dose. Groups IV and V received lisinopril ( 0.225 mg/kg and 0.45 mg/kg), while Gro...

Alzheimer's disease, a progressive neurodegenerative disease, affects learning and memory resulting from cholinergic dysfunction. Scopolamine has been employed to induce Alzheimer's disease-like pathology in vivo and in vitro through alteration of cholinergic system. N-benzylcinnamide (PT-3), purified from Piper submultinerve, has been shown to exhibit neuroprotective properties against amyloid...

OBJECTIVE To use multivariate statistical analysis of EEG data in order to separate EEGs of patients with Alzheimer's disease (AD) from controls. A group of individuals with mild cognitive impairment (MCI) was evaluated using the same methodology. Additionally, the effects of scopolamine on this separation are studied. METHODS Statistical pattern recognition (SPR) is used in conjunction with ...

Objective of this study was to evaluate Guggul extract for the treatment of Alzheimer’s disease using scopolamine induced amnesia in mice on Morris water maze. Guggul extract (50mg/kg) was administered orally for fifteen successive days followed by Scopolamine (0.4 mg/kg i.p.) from 15 th to 18 th day in mice. Morris water maze was employed to evaluate learning and memory using parameter like Es...

Adjudge the neuroprotective ability of Ellagic acid (EA) as a constructive herbal drug to impede cholinergic dysfunctions and oxidative stress in Alzheimer’s disease (AD) in chronically administered scopolamine induced Alzheimer’s type dementia in rats. Alzheimer’s type dementia was induced by chronically administered intraperitoneal injection of scopolamine (0.7 mg/kg) to rats for period of 7 ...

The firing of rat hippocampal pyramidal cells is determined both by the animal's location and by the state of the hippocampal EEG. Because cholinergic transmission plays a role in EEG activity, we expected that its modification would alter place cell activity. We therefore investigated the effects on place cell activity of blocking muscarinic transmission with intracerebroventricular injections...

We evaluated the neuropharmacological effects of 30% ethanolic pine needle extract (PNE) on memory impairment caused by scopolamine injection in mice hippocampus. Mice were orally pretreated with PNE (25, 50, and 100 mg/kg) or tacrine (10 mg/kg) for 7 days, and scopolamine (2 mg/kg) was injected intraperitoneally, 30 min before the Morris water maze task on first day. To evaluate memory functio...

Background: It has been suggested that curcumin may be useful in diseases with cognitive dysfunction because it slows the progression and leads to the improvement of cognitive functions. In this study, the protective effects of curcumin on scopolamine-induced rat models of cognitive impairment were evaluated. Methods: 21 male Wistar Albino rats, 1 year old, 200±25 grams, were included in the s...
