Evaluation of neuroactive effects of ethanol extract of Schisandra chinensis, Schisandrin, and Schisandrin B and determination of underlying mechanisms by zebrafish behavioral profiling.

Numai utilizatorii înregistrați pot traduce articole

Schisandra chinensis, a traditional Chinese medicine (TCM), has been used to treat sleep disorders. Zebrafish sleep/wake behavioral profiling provides a high-throughput platform to screen chemicals, but has never been used to study extracts and components from TCM. In the present study, the ethanol

[Selection of mobile phases for the determination of gamma-schisandrin and multi-active constituents in Schisandra chinensis and its preparations by high performance liquid chromatography].

Numai utilizatorii înregistrați pot traduce articole

The systems of mobile phase for the determination of gamma-schisandrin in Schisandra chinensis and its preparations were developed by high performance liquid chromatography (HPLC). The separation was performed on a Shim-pack VP-ODS column (250 mm x 4.6 mm, 5 microm) at 30 degrees C, the detection

Preparative separation and purification of deoxyschisandrin and gamma-schisandrin from Schisandra chinensis (Turcz.) Baill by high-speed counter-current chromatography.

High-speed counter-current chromatography (HSCCC) was successfully applied to the preparative separation and purification of deoxyschisandrin and gamma-schisandrin from the crude petroleum ether extracts of Schisandra chinensis (Turcz.) Baill. The optimum solvent system composed of

Ultrasound-assisted extraction and purification of schisandrin B from Schisandra chinensis (Turcz.) Baill seeds: optimization by response surface methodology.

Numai utilizatorii înregistrați pot traduce articole

The objective of this study is to develop a process consisting of ultrasonic-assisted extraction, silica-gel column chromatography and crystallization to optimize pilot scale recovery of schisandrin B (SAB) from Schisandra chinensis seeds. The effects of five independent variables including

Schisandrin B inhibits LPS-induced inflammatory response in human umbilical vein endothelial cells by activating Nrf2.

Numai utilizatorii înregistrați pot traduce articole

Schisandrin B (SchB), an active ingredient extracted from Schisandra chinensis (Turcz.) Baill, has been known to have anti-oxidant and anti-inflammatory activities. In this study, we investigated the anti-inflammatory effects and mechanism of SchB in LPS-stimulated human umbilical vein endothelial

Schisandrin B improves cerebral ischemia and reduces reperfusion injury in rats through TLR4/NF-κB signaling pathway inhibition

Numai utilizatorii înregistrați pot traduce articole

It has been established that poor outcomes in ischemic stroke patients are associated with the post-reperfusion inflammatory response and up-regulation of TLR4. Therefore, suppression of the TLR4 signaling pathway constitutes a potential neuroprotective therapeutic strategy. Schisandrin B, a

Attenuation of cyclosporine A induced nephrotoxicity by schisandrin B through suppression of oxidative stress, apoptosis and autophagy.

Numai utilizatorii înregistrați pot traduce articole

Cyclosporine A (CsA) is a potent immunosuppressive agent whose clinical usage is limited by nephrotoxicity. Schisandrin B (SchB), isolated from the fruit of Schisandra chinensis, is a natural compound with multiple pharmacological activities that has been shown to attenuate organ injury caused by

Beneficial effects of schisandrin B on the cardiac function in mice model of myocardial infarction.

Numai utilizatorii înregistrați pot traduce articole

The fruit of Schisandra chinensis has been used in the traditional Chinese medicine for thousands of years. Accumulating evidence suggests that Schisandrin B (Sch B) has cardioprotection effect on myocardial ischemia in vitro. However, it is unclear whether Sch B has beneficial effects on continuous

The protective mechanism of schisandrin A in d-galactosamine-induced acute liver injury through activation of autophagy.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The principal bioactive lignan of Schisandra chinensis fructus, commonly used for traditional Chinese medicine, is schisandrin A. Schisandrin A has been widely reported as being very effective for the treatment of liver disease. However, the mechanisms of its protective effects in liver

A novel experimental model of acute hypertriglyceridemia induced by schisandrin B.

Numai utilizatorii înregistrați pot traduce articole

Mice were intragastrically treated with single doses (0.05-0.8 g/kg) of schisandrin B (a dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis). Twenty-four hours after schisandrin B administration, the serum triglyceride level was increased by 10-235% in a dose-dependent

Schisandrin A and B affect subventricular zone neurogenesis in mouse.

Numai utilizatorii înregistrați pot traduce articole

Schisandrin A and B (Sch A and B) are the main effective components extracted from the oriental medicine Schisandra chinensis which is traditionally used to enhance mental and intellectual function. Although their neuroprotective effects have been demonstrated, their influences on neurogenesis are

Inhibitory effect of schisandrin on spontaneous contraction of isolated rat colon.

Numai utilizatorii înregistrați pot traduce articole

This study examined the effect of schisandrin, one of the major lignans isolated from Schisandra chinensis, on spontaneous contraction in rat colon and its possible mechanisms. Schisandrin produced a concentration-dependent inhibition (EC₅₀=1.66 μM) on the colonic spontaneous contraction. The

Schisandrin B displays a protective role against primary pulmonary hypertension by targeting transforming growth factor β1.

Numai utilizatorii înregistrați pot traduce articole

Pulmonary arterial smooth muscle cells (PASMCs) in the medial layer of the vessel wall are involved in vessel homeostasis, but also for pathologic vascular remodeling in diverse diseases, such as pulmonary arterial hypertension (PAH). Pulmonary vascular remodeling in PAH results in vascular

Long-term schisandrin B treatment mitigates age-related impairments in mitochondrial antioxidant status and functional ability in various tissues, and improves the survival of aging C57BL/6J mice.

Numai utilizatorii înregistrați pot traduce articole

Mitochondrial decay is a major cause of aging, leading to the subsequent death of aerobic organisms including humans. In the present study, we examined the effects of supplementation with schisandrin B (Sch B, a dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis),

Effective kinetics of schisandrin B on serum/hepatic triglyceride and total cholesterol levels in mice with and without the influence of fenofibrate.

Numai utilizatorii înregistrați pot traduce articole

Schisandrin B, an active ingredient isolated from the fruit of Schisandra chinensis, increased serum and hepatic triglyceride levels in mice. In the present study, the effective kinetics of schisandrin B on serum/hepatic triglyceride and total cholesterol levels in mice without and with the
