CONTEXT  Nauclea latifolia Smith (Rubiaceae) is a small tree found in tropical areas in Africa. It is used in traditional medicine to treat malaria, epilepsy, anxiety, pain, fever, etc. OBJECTIVE  The aim of this study was to investigate the effects of Nauclea latifolia roots decoction on the peripheral and central nervous systems and its possible mechanisms of action. MATERIALS AND METHODS...

This study aimed to evaluate the orofacial antinociceptive effect of the Cymbopogon winterianus essential oil (LEO) complexed in β-cyclodextrin (LEO-CD) and to assess the possible involvement of the central nervous system (CNS). The LEO was extracted, chromatographed, and complexed in β-cyclodextrin. The complex was characterized by differential scanning calorimetry (DSC) and thermogravimetry d...

Scoparia dulcis Linn. (SD) is a perennial herb that has been well studied for its antioxidant, anti-inflammatory, antidiabetic, and hepatoprotective effects. However, scientific information on SD regarding the neuropharmacological effect is limited. This study evaluated the sedative and hypnotic effect of the ethanolic extract of whole plants of Scoparia dulcis (EESD). For this purpose, the who...

OBJECTIVE Sleeplessness is the most common sleep disorder. In this study the hypnotic effect of the hydro-alcoholic extract (HAE) of Perovskia abrotanoides Karel. and its water fraction (WF), ethyl acetate fraction (EAF) and n-butanol fraction (NBF) were studied in mice. MATERIALS AND METHODS The test compounds were administered intraperitoneally to mice 30 min before the administration of so...

Parkinson's disease is one of the most common neurodegenerative disorders affecting large majority of population who are older than age of 65. Apart from dopamine, acetylcholine and glutamate, adenosinc has also been identified in the basal ganglia. Adenosine modulates the release of a variety of neurotransmitters including dopamine. In order to establish adenosine-dopamine interactions in drug...

Opuntia ficus-indica var. saboten. is widely cultivated in Jeju Island (South Korea) for use in manufacture of health foods. This study described antidepressant effect of two flavonoids (kaempferol and quercitrin) isolated from the Opuntia ficus-indica var. saboten. The expression of the hypothalamic POMC mRNA or plasma β-endorphin levels were increased by extract of Opuntia ficus-indica var. s...

BACKGROUND AND PURPOSE We determined long-term functional outcome in a well-characterized mouse model of mild focal cerebral ischemia. METHODS We subjected 129/SV mice to sham operation or 30 minutes of left middle cerebral artery occlusion (MCAo) followed by reperfusion (89% survival rate). Six weeks later, animals were tested for neurological deficits, motor coordination on an accelerating ...

BACKGROUND Both propofol and volatile anesthetics have been reported to interact with the endocannabinoid system. The purpose of this study was to evaluate the effect of selective agonists for cannabinoid receptor types 1 and 2 on etomidate-induced sedation. METHODS A controlled, blinded, experimental study was performed in 20 mice that received intraperitoneal injections of etomidate, the ca...

Recently we demonstrated that docosahexaenoic acid (DHA) is highly neuroprotective when animals were allowed to survive during one week. This study was conducted to establish whether the neuroprotection induced by DHA persists with chronic survival. Sprague-Dawley rats underwent 2h of middle cerebral artery occlusion (MCAo) and treated with DHA or saline at 3h after MCAo. Animals received neuro...
