Abstract
The Danchunwhangagam (DCWGG) has long been used for various cerebrovascular diseases. However, little scientific investigation has been carried out. Cytokines involved in the regulation of inflammatory reactions and immune responses may play a role in the pathogenesis of cerebral infarction (CI). The aim of the present study is to investigate the effect of DCWGG on the production of proinflammatory cytokines in peripheral blood mononuclear cells (PBMCs) from CI patients. The amount of tumor necrosis factor (TNF)-α, interleukin (IL)-1α, IL-1β, IL-6, and IL-8 in PBMC culture supernatant was significantly increased in the lipopolysaccaride (LPS)- or desferrioxamine (DFX)-treated cells compared with unstimulated cells. We showed that DCWGG inhibited the production of TNF-α, IL-1α, IL-1β IL-6, and IL-8 induced by LPS in a dose-dependent manner. Also, DCWGG inhibited TNF-α, IL-1α, IL-β, IL-6, and IL-8 production-induced DFX in dose-dependent manner. These results suggest that DCWGG might have regulatory effects on LPS- or DFX-induced cytokine production, which might explain its beneficial effect in the treatment of CI.
