Danggui‑Sayuk‑Ga‑Osuyu‑Senggang‑Tang ameliorates cold‑induced vasoconstriction in vitro and in vivo.

Danggui-Sayuk-Ga-Osuyu-Senggang-Tang (DSGOST), one of the traditional Chinese medicines, has long been prescribed for patients suffering from Raynaud phenomenon (RP) in Northeast Asian countries, including China, Japan and Korea. Although a previous in vitro study from our laboratory revealed that DSGOST prevents cold (25˚C)‑induced RhoA activation and endothelin‑1 (ET‑1) production in endothelial cells (ECs), the mechanisms by which DSGOST is able to alleviate the symptoms of RP have yet to be fully elucidated. The present study aimed to demonstrate that DSGOST regulates RhoA‑mediated pathways in cold‑exposed pericytes.

Antiinflammatory effects of Epimedium brevicornum water extract on lipopolysaccharide-activated RAW264.7 macrophages.

Epimedium brevicornum Maxim (Berberidaceae) possesses estrogenic properties. It is one of the most widespread herbal remedies used in Oriental medicine. The present study investigated the effects of Epimedium brevicornum water extract (EB) on proinflammatory mediators secreted from lipopolysaccharide (LPS)-induced RAW264.

Antidepressant effects of Soyo-san on Immobilization stress in ovariectomized female rats.

Soyo-san is a traditional oriental medicinal formula, a mixture of 9 crude drugs, and it has been clinically used for treating mild depressive disorders. The purpose of the study was to examine the effect of Soyo-san on repeated stress-induced alterations of learning and memory on a Morris water maze (MWM) task and also the anxiety-related behavior on the elevated pulse maze (EPM) in ovariectomized female rats. We assessed the changes in the reactivity of the cholinergic system by measuring the immunoreactive neurons of choline acetyltransferase (ChAT) and reactivity of acetylcholinesterase (AChE) in the hippocampus, and the serum levels of corticosterone were assessed after behavioral testing.
