AIM: To study the effects of huperzine A (HupA) on neuritogenic activity and the expression of nerve growth factor (NGF).
Abstract
BACKGROUND:
The benefit of Ginkgo biloba has been discussed controversially. The aim of this review was to assess the effects of Ginkgo biloba in Alzheimer's disease as well as vascular and mixed dementia covering a variety of outcome domains.
The lysosome hypothesis of aging predicts that membrane stabilizers will extend life-span. Stabilizers containing the dimethylaminoethanol moiety (DMAE) have been reported to extend the life-span of drosophila and mice. We tested the prediction in Japanese quail (N = 15) by administering DMAE bitartrate (18.4 mg/kg/day) in the drinking water for 69 weeks, starting at 195 weeks of age. A...
AbstractMETHODS:Various developmental problems including attention-deficit/hyperactivity disorder (ADHD) have been linked to biological deficiencies in polyunsaturated fatty acids (PUFAs). Additionally, there is evidence that symptoms may be reduced with PUFA supplementation. This study investigated effects of supplementation with PUFAs on symptoms typically associated with ADHD. Because nutrients work synergistically, additional effects of micronutrient supplementation were also investigated. A total of...
Abstract Psycho-behavioural inhibition is characteristic of major depressive disorder and frequently recedes after the other depressive symptoms. This may induce an important psychosocial impairment which could be a risk factor for relapse. METHODS: The aim of this eight weeks, multicentric, randomized, double blind, placebo controlled trial was to assess the efficacy and safety of sulbutiamine (Arcalion) [600...
Previous human studies revealed that l-theanine influences brain function. The current study was designed to evaluate the affect of l-theanine (Suntheanine®) on attention and reaction time response in 18 normal healthy University student volunteers. In accordance with preliminary analysis of the manifest anxiety scale (MAS), the subjects were divided into two groups referred to as high anxiety propensity group...
Abstract In vitro preincubation of brain membranes of aged mice with piracetam (0.1-1.0 mmol/L) enhanced membrane fluidity, as indicated by decreased anisotropy of the membrane-bound fluorescence probe 1,6-diphenyl-1,3,5-hexatriene (DPH). Piracetam had similar in vitro effects on brain membranes of aged rats and humans, but it did not alter brain membrane fluidity in young mice. Chronic treatment of young and...

Abstract The derivatives of GABA and beta-phenylethylamine (PEA) the tranquilizer phenibut and muscle relaxant baclofen (p-chloro-beta-phenyl-GABA, lioresal) diminished all studied effect of PEA in mice, namely seizures, sedation, excitation, hyperthermia. Diazepam diminished only seizures whereas haloperidol excitation and hyperthermia. PEA injections anatogonized (the sedative and hypothermic effects of phenibut and diazepam and the anticonvulsant (against l-kynurenine) effect of phenibut...
The pharmacological mechanism of action of the piracetam-like nootropics is still obscure. Their unique feature is that they exert distinct effects on memory, but show hardly any biochemical activity and are practically devoid of toxic effects. Our results indicate that the memory-enhancing action of these substances is dependent on the presence of the adrenals, suggesting that their central effects...
