Grape Seed Extract Attenuates Demyelination in Experimental Autoimmune Encephalomyelitis Mice by Inhibiting Inflammatory Response of Immune Cells.

Objective: To examine the anti-inflammatory effect of grape seed extract (GSE) in animal and cellular models and explore its mechanism of action.

Methods: This study determined the inhibitory effect of GSE on macrophage inflammation and Th1 and Th17 polarization in vitro. Based on the in vitro results, the effects and mechanisms of GSE on multiple sclerosis (MS)-experimental autoimmune encephalomyelitis (EAE) mice model were further explored.

Fasudil mediates cell therapy of EAE by immunomodulating encephalomyelitic T cells and macrophages.

Although Fasudil has shown therapeutic potential in EAE mice, the mechanism of action are still not fully understood. Here, we examined the immunomodulatory effect of Fasudil on encephalitogenic mononuclear cells (MNCs), and tested the therapeutic potential of Fasudil-treated MNCs in active EAE. Fasudil inhibited expression of CCL20 on T cells and migration of T cells, decreased CD4(+) IFN-γ(+) and CD4(+) IL-17(+) T cells, but increased CD4(+) IL-10(+) and CD4(+) TGF-β(+) T cells.

Axillary arteriovenous fistula after axillary plexus block.

This report presents the case of a 51-year-old man who had an axillary arteriovenous fistula (AVF) as a complication of an axillary plexus block that was performed for internal fixation for a right forefinger phalanx fracture 4 years previously. While performing the axillary plexus block, a 22-gauge needle was placed inside the axillary sheath by observing the pulsations of the axillary artery. A pulsatile mass was found in the right axilla 1 day after the block was performed.
