Influence of long-term administration of rutin on spatial memory as well as the concentration of brain neurotransmitters in aged rats.
Journal Title: Pharmacological Reports - Year 2012, Vol 64, Issue 4
Abstract
Background: The present study was designed to investigate the behavioral and neurochemical effects of long-term oral rutin administration to old male WAG rats (100 and 200 mg/kg b.w./day). Rutin is a well-known dietary flavonol glycoside with antioxidant and anti-inflammatory properties. Methods: First, spatial memory was assessed in the water maze and then the levels of neurotransmitters in selected brain regions were estimated. Results: There was enhanced spatial memory in aged rats pretreated with the smaller dose of rutin in the probe trial of the water maze, nevertheless, augmented levels of noradrenaline in the hippocampi of these animals were not correlated with improved spatial memory. The increased dopamine levels in the hypothalami of the same group of animals may suggest effects other than behavioral. Conclusion: Long-term rutin pre-treatment may cause behavioral and neurochemical changes in aged WAG male rats.

Synthesis and 5-HT1A/5-HT2A activity of some butyl analogs in the group of phenylpiperazine alkyl pyrimido[2,1-f]theophyllines.
New arylpiperazines with a four-methylene spacer containing a terminal pyrimido[2,1-f] theophylline fragment were synthesized, and their 5-HT1A and 5-HT2A receptor affinities were determined. All these compounds displaye...
Antinociceptive effect of lidocaine in rats.
Lidocaine, a local anesthetic drug, exerts its effect by blocking sodium channels in peripheral sensory neurons. It is commonly used in clinical practice as a local anesthetic drug. This study was undertaken in order to...
Acute effect of ethanol on IgA immunoreactive cells in the intestine-associatedimmune system.
The purpose of this study was to investigate the acute effect of ethanolon mucosa-associated lymphoid tissue at the level of Peyer's patches and the intestinal lamina propriain female rats and to determine whether this a...
Antithrombotic effect of captopril and enalapril in old rats.
In the present study, we have shown considerably accelerated thrombosis in old rats in comparison with adult rats, which may be related to the impaired hemostatic balance in these animals. In old rats, captopril and enal...
Tropane alkaloids as medicinally useful natural products and their synthetic derivatives as new drugs.
Secondary metabolites of Solanaceae plants, sharing tropane skeleton as a common structural feature, are sharply divided into two classes: tropine and ecgonine derivatives. The first group, represented by well known alka...
