Biochemical markers associated with the prognosis of depression in humans are being described in the literature, whereas experimental studies in animal models in search for antidepressant strategies are lacking. The aim of this study was to evaluate platelet morphology, platelet activity and nitric oxide (NO) synthesis as possible biomarkers of(More)
Tilia genus is commonly used around the world for its central nervous system properties; it is prepared as tea and used as tranquilizing, anticonvulsant, and analgesic. In this study, anticonvulsant activity of the Tilia americana var. mexicana inflorescences and leaves was investigated by evaluating organic and aqueous extracts (100, 300, and 600 mg/kg,(More)
P-glycoprotein (P-gp) has been associated with pharmacoresistance and mechanisms regulating the membrane potential. However, at present it is unknown if P-gp overexpression in brain is associated with changes in membrane depolarization in refractory epilepsy. Experiments were designed to evaluate the membrane depolarization and P-gp overexpression induced(More)
Tilia americana and Annona diversifolia are plants widely distributed in Mexico and sold in markets for their medicinal properties on the central nervous system (CNS) including possible neuroprotection. Pharmacological studies have corroborated CNS activities due to flavonoid constituents, but evidence of their neuroprotector effects are lacking. This study(More)
Rutin is a bioflavonoid found in medicinal plants used to reduce anxiety. Evidence is lacking of rutin's anxiolytic-like activity, putative mechanism(s) of action, and neural sites of effects. The basolateral amygdala (BLA) is the main brain region that regulates anxiety, through GABAA/benzodiazepine (BDZ) receptors, which are modulated by flavonoids.(More)
Although Salvia divinorum is traditionally known as a 'mind-altering' or psychoactive herb used, among others things, as a tranquilizer, this property has not been validated with regard to its efficacy and safety. The objective of this study is to provide evidence for the sedative effects of S. divinorum and discriminate the nature of the responsible(More)
OBJECTIVE In the present study, the effect of stimulation of the Po-shen and Shen-hun scalp-acupuncture bands on tissue amino acid concentrations in several brain regions in awake and pentobarbital-sedated immature rats was evaluated. MATERIALS AND METHODS Sprague-Dawley rats (aged 15 days) were organized in four groups of at least eight animals: control(More)
