Hypertension has been approved to cause disharmony between the heart and kidney such as cardiac hypertrophy and kidney dysfunction. In traditional oriental medicine Paeo-tang (PET) has been shown to have effects on blood circulation improvement. However, the beneficial effect of PET on hypertension remains unknown. In this study, we investigated that PET attenuates blood pressure and improves cardiovascular and renal function in NG-nitro-L-arginine methylester (L-NAME) rat model. Hypertensive rat models were induced by the administration of L-NAME (40 mg/kg/day) and then PET (50 or 100 mg/kg/day) or Olmetec was treated for 2 weeks. PET treatment significantly suppressed the systolic blood pressure and decreased intima-media thickness in the thoracic aorta. PET ameliorated endothelium-dependent and independent vascular relaxation in the L-NAME-induced vascular dysfunction. PET ameliorated the functional decline in the kidney such as albumin and blood urea nitrogen in plasma. These results demonstrated that PET possesses protective effects against L-NAME-induced hypertension.

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.
