To certify the protective effect of herbal medicine on myocardial damage against oxygen free radical-induced myocardiotoxicity, cytotoxicity was measured using by MTT assay, LDH activity and thiobarbituric acid reactive substances(TBARS) assay in the presence of Guaruhaebaekbaekju-tang(GHBT) extracts or single constituents of this prescription, Myocardial toxicity was evaluated in neonatal rat myocardiocytes in cultures. In the present study, xanthine oxidase/hypoxanthine (XO/HX) resulted in a decrease in cell viability, an increase in LDH activity in culture medium and lipid peroxidation in cultured myocardial cells, In the effect of GHBT extract, it showed the prevention from the XO/HX-induced cardiotoxicity such as the decrease of LDH activity and lipid peroxidation. In the protective effect of Fructus Trichosanthis (FT) and Bulbus Allii Macrostemi (BAM), all the extracts were significantly effective in the protection of XO/HX-induced cardiotoxocity in cultured myocardial cells. From these results, they show that XO/HX is cardiotoxic in cultured myocardial cells derived from neonatal rats, and it suggests that GHBT, FT and BAM extracts are positively effective in the blocking XO/HX-induced cardiotoxicity.

Objective: The purpose of this study was to evaluate the effects of traditional Korean medicine, including Gwaruhaebackbackju-tang and Gwaruhaebackbanha-tang, on idiopathic atypical chest pain. Method: Herbal medicine and acupuncture were carried out. NRS scores were used to evaluate the effect of the treatments. Results: After the treatments, the patients' chest pain improved, as the NRS score decreased. Conclusion: This study suggests that traditional Korean medicine treatments might be effective for idiopathic atypical chest pain.

Objectives: This study was designed to evaluate the macrophages polarization of traditional Korean medicine on cardiac pain about Geum-Gwe-Yo-Ryak's two prescriptions including Kwaruhaebaekbanha-tang (KHB) and Kwaruhaebaekpaekju-tang (KHP). Materials and methods: Flow cytometry analysis was used to measure the changes in the ratio of M1 type and M2 type macrophages. Protein expression of nuclear factor-like 2 (Nrf2), heme oxygenase-1 (HO-1), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) were measured by Western Blot, and ABCA1 and SR-B1 were detected by real time PCR (RT-PCR). Intracellular lipid accumulation was measured by Oil Red O staining (ORO staining). Results: KHB and KHP increase anti-oxidative activity related protein levels including Nrf2 and HO-1. Furthermore, KHB and KHP inhibit lipid accumulation on intracellular levels through induction of ATP binding receptor cassette subfamily A member 1 (ABCA1) and scavenging receptor class B member 1 (SR-B1), respectively. Finally, KHB and KHP also blocked pro-inflammatory mediators including tumor necrosis factor-alpha ($TNF{\alpha}$) and interleukin-6 (IL-6), iNOS and COX-2 expression. Conclusion: This study suggests that KHB and KHP potently regulate the M1/M2 macrophage polarization.
