TNF-α로 유도된 혈관내피세포의 혈관염증에 미치는 오적산(五積散)의 억제 효과 = Inhibitory Effects of Ojeoksan on TNF-α-induced Vascular Inflammation in Human Umbilical Vein Endothelial Cells

다국어 초록 (Multilingual Abstract)

Objectives : Ojeoksan, originally recorded in an ancient Korean medicinal book named “Donguibogam” and has been used for the treatment of circulation disorder of blood which was called blood accumulation (血積) in Korean medicine. Therefore, this study was carried out to investigate the beneficial effect of OJS on vascular inflammation in HUVECs.
Methods : We evaluated the effect of OJS on the expression of cell adhesion molecules and protective role in HUVEC stimulated by TNF-α by using Western blot.
Results : Pretreatment with OJS decreased the adhesion of HL-60 cells to TNF-α-induced HUVEC. OJS suppressed TNF-α-induced expression level of cell adhesion molecules such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1(VCAM-1), and endothelial cell selectin (E-selectin). Moreover, OJS significantly decreased TNF-α-induced production of intracellular reactive oxygen species (ROS); and inhibited the phosphorylation of IκB-α in the cytoplasm compared to the experimental group. Pretreatment with OJS inhibited the trans-location of NF-κB p65 to the nucleus. OJS also inhibited phosphorylation of MAPKs compared to the experimental group. OJS significantly increased the protein expression of Nrf2 and HO-1.
Conclusions : Ojeoksan has a protective effect on vascular inflammation, and might be a potential therapeutic agent for early atherosclerosis.
