background: the spice zingiber officinale or ginger possesses antioxidant activity and neuroprotective effects. in this study we hypothesized that treatment with hydroethanolic extract of ginger (50, 100 and 200 mg/kg, p.o) would effect on the hyoscine-induced memory impairment in rats. methods: in this experimental study 64 male wistar rats were divided into eight groups (8 rats in each group)...

Different effects of scopolamine on learning, memory, and nitric oxide (NO) metabolites in hippocampal tissues of ovariectomized (OVX) and sham-operated rats were investigated. The animals in the Sham-Scopolamine (Sham-Sco) and OVX-Scopolamine (OVX-Sco) Groups were treated with 2 mg/kg scopolamine before undergoing the Morris water maze, while the animals in the Sham and OVX Groups received sal...

Scopolamine is a high affinity muscarinic antagonist that is used for the prevention of post-operative nausea and vomiting. 5-HT3 receptor antagonists are used for the same purpose and are structurally related to scopolamine. To examine whether 5-HT3 receptors are affected by scopolamine we examined the effects of this drug on the electrophysiological and ligand binding properties of 5-HT3A rec...

OBJECTIVE An epidemic of scopolamine poisonings occurred in Oslo in 2008 among users of illicit drugs, caused by fake Rohypnol pills. The clinical features, diagnostic process, and handling of the epidemic are presented. METHODS Suspected cases of scopolamine poisoning were extracted by reviewing registration forms from an ongoing prospective clinical study of acute poisonings in Oslo. Medica...

Glucose injections attenuate deficits in memory under several conditions in both rodents and humans. The present study examined effects of glucose on memory in two such amnesic populations, scopolamine-treated and old mice, and then assessed effects of glucose on brain (lHJ2deoxyglucose (2DG) uptake. In Experiment lA, scopolamine (3 mg/kg, i.p.) significantly impaired performance of mice tested...

Transdermal drug delivery systems are involved in the continuous administration of drug molecules from the surface of the skin into the circulatory system. Such systems have proved advantageous for delivery of certain drugs, such as scopolamine, nicotine, nitroglycerine, and estradiol. Compared with oral administration, transdermal drug delivery offers better uniformity of drug concentrations i...

Hyoscyamine (atropine) and scopolamine are the predominant tropane alkaloids in the Datura genus, occurring in all plant organs. The assessment of the alkaloid content of various plant parts is essential from the viewpoint of medical use, but also as a potential risk of toxicity for humans and animals. Therefore, a reliable method for the determination of tropane alkaloid content is of high imp...

1 The effect of S 15535 (4-benzodioxan-5-yl)1-(indan-2-yl)piperazine), an agonist at presynaptic and antagonist at postsynaptic 5-HT1A receptors, on the impairment of spatial learning caused by intrahippocampal scopolamine in a two-platform spatial discrimination task was studied. 2 Scopolamine (4.0 microg microl-1), injected bilaterally into the CA1 region of the dorsal hippocampus 10 min befo...
