Anti-Inflammatory Effects of Schisandrin B on LPS-Stimulated BV2 Microglia via Activating PPAR-γ.

Schisandrin B (Sch B), a dibenzocyclooctadiene lignan isolated from Schisandra chinensis (Turcz.) Baill, has been shown to have anti-inflammatory effect. The purpose of this study was to evaluate the effect of Sch B on LPS-induced inflammation in microglia and to investigate the molecular targets of Sch B.

Flunarizine blocks voltage-gated Na(+) and Ca(2+) currents in cultured rat cortical neurons: A possible locus of action in the prevention of migraine.

Although flunarizine (FLN) has been widely used for migraine prophylaxis with clear success, the mechanisms of its actions in migraine prophylaxis are not completely understood. It has been hypothesized that migraine is a channelopathy, and abnormal activities of voltage-gated Na(+) and Ca(2+) channels might represent a potential mechanism of cortical hyperexcitability predisposing to migraine. The aim of the present study was to investigate the effects of FLN on Na(+) and Ca(2+) channels of cultured rat cortical neurons.
