Objectives : Cheongnoimyungshin-hwan (CNMSH) is a Herbal compound prescription that is composed mainly of herbal medicines such as Ginseng Radix Alba, Angelicae Gigantis Radix, Dioscoreae Rhizoma, Longan Arillus and cornus cervi parvum, and for the purpose of improving memory and preventing dementia. Methods : In this study, it was investigated whether CNMSH could suppress inflammatory response and oxidative stress in the lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells. As a result, CNMSH decreased expression of inducible nitric oxide (NO) synthase and cyclooxygenase-2, and also inhibited production of NO, prostaglandin E2. Results : This effect was associated with the suppression of the expression of p65, one of the nuclear factor-kappaB ($NF-{\kappa}B$) subunits, and increased expression of $I{\kappa}B-{\alpha}$, inhibit the $NF-{\kappa}B$ transcription factor. In addition, CNMSH significantly blocked intracellular reactive oxygen species accumulation in response to LPS stimulation. Furthermore, CNMSH increased expression of nuclear factor erythroid 2-related factor (Nrf)-2 activation and heme oxygenase (HO)-1. Conclusions : Therefore, it has been shown anti-inflammatory and antioxidant effects by inhibiting the expression and production of inflammatory mediators in LPS-stimulated macrophages, and is associated with ROS generation and is activated by Nrf2/HO-1 signaling pathway.

Objective: To describe the effects of Korean medical treatment on a 51-year-old male patient with polyneuropathy and chief complaints of lower limb paralysis and dysarthria. Methods: The Toronto Clinical Neuropathy Scoring System (TCNSS) was used to evaluate the function of the lower limb and the symptoms of the patient were observed daily. We applied herbal medication and acupuncture daily, depending on the patient’s symptoms. Results: After the treatment, the TCNSS score was improved. Conclusions: In this case, Korean medical therapy was effective in improving lower limb function.

Objectives: The aim of this study was to report the current status of the Korean traditional medicine side effects described in domestic western medical journals in the past 10 years. Methods: We searched for domestic western medical papers about Korean traditional medicine side effects cases from January 1, 2008, to August 31, 2017. Results: Thirty papers were selected from 31 studies. The number of papers of side effects caused by acupuncture was 21 (70%), by herbal medication was 7 (23%) and by thread lifting was 2 (7%). The number of papers of side effects caused by Korean medical doctors was 20 (66.8%), by non-medical persons including patients was 2 (6.6%), by herbal pharmacists was 1 (3.3%), by multiple practitioners, including Korean medical doctors, was 1 (3.3%), and by unknown persons was 6 (20%). Reported side effects were mostly mild, except for death and severe side effects. Conclusions: Studies of Korean traditional medicine side effects are short, and in-depth studies of stability are needed. These studies will improve the safety of the Korean traditional medicine.

Objectives: This study investigated the aconitine contents analysis of Buja extracts (raw material of Buja, hot water extract of Buja, and hot water extract of Sambu-tang) and the single oral dose toxicity of Sambu-tang-R in six-week-old Sprague-Dawley rats in order to compare the toxicity of Buja extracts.Methods: Aconitine content analysis is that Buja extracts were hold purity test. To detect single oral dose toxicity, six-week-old Sprague-Dawley rats were divided into two groups, a normal control group and a sambutang-R (2,000 mg/kg) group. For 14 days of treatment, clinical signs, body weight, clinical chemistry, necropsy, and histopathology were examined.Results: The aconitine contents of the Buja extracts were Buja-RH (0.1738%), Buja-RD (0.1746%), and Sambu-tang-R (0.0961%). There were no cases of death in either the control group or the experimental group. Nor was there any disorder to the clinical signs or any significant change in body weight in either group. There was no significant change of clinical chemistry or disorder of necropsy findings in either the control or the experimental group. And there was no difference in histopathological findings in comparing the control group with the experimental group.Conclusions: These results suggest that the aconitine content of the hot water extract of Buja was similar to the raw material of Buja, but the hot water extract of Sambu-tang had greatly decreased aconitine content. These results also suggest that a single oral lethal dose of Sambu-tang-R for Sprague-Dawley rats exceeds 2,000 mg/kg for both female and male rats.

Objectives: The aim of this study was to report the clinical effects of a combination of Gamiguibi-tang and sweet bee venom on a patient with Raynaud's disease. Methods: The patient with Raynaud's disease was treated with Gamiguibi-tang three times a day for 43 days and with sweet bee venom daily. The effects on Raynaud's disease were measured on both hands using a cold stress test and an infrared thermometer and by digital infrared thermographic imaging and a NRS (Numeric Rating Scale). We conducted the cold stress test at 6-8 day intervals from 2016.04.27 to 2016.06.08. Results: After treatment, the symptoms of pain were decreased in both hands and digital infrared thermographic imaging (DITI) confirmed a rise in the temperature of the fingers. The fingertip temperature increased from 29.6 to 30.4 degrees and the cooling/rewarming ratio (CRR) increased steadily. No adverse events were found at discharge. Conclusions: Gamiguibi-tang combined sweet bee venom may improve symptoms in patients with Raynaud's disease.

다양한 질병의 발병 및 진행을 예방하기 위해 오랫동안 사용되어 온 대계는 항산화 활성을 포함하여 광범위한 생리 활성을 갖는 것으로 보고되었으나, 간세포에서의 효능에 대한 연구는 여전히 미비한 실정이다. 본 연구에서는 간세포에서 대계 에탄올 추출물(EECJ)의 항산화 활성 및 관련 기전을 조사하기 위해 인간 간세포암종 HepG2 세포주를 선택하였고, 산화적 스트레스를 모방하기 위해 H₂O₂를 처리하였다. 본 연구 결과에 따르면 EECJ는 H₂O₂가 처리된 HepG2 세포에서 세포 생존율의 감소와 LDH의 방출을 유의적으로 억제하였다. EECJ는 또한 세포 형태학적 변화의 관찰, 유세포 분석 및 LC3의 발현 결과에서 입증된 바와 같이 H₂O₂에 의해 유도된 자가포식을 유의하게 감소시켰으며, H₂O₂에 의해 유도된 세포사멸과 세포주기의 교란을 약화시켰다. 이는 H₂O₂에 노출된 HepG2 세포가 EECJ에 의하여 지속적인 세포 분열과 증식이 유지되고 있음을 의미한다. 또한, EECJ가 강력한 항산화 활성을 가지고 있음을 세포 내 ROS 및 미토콘드리아 슈퍼옥사이드 생산의 차단으로 확인하였으며, 이는 H₂O₂에 의해 감소된 세포 내 GSH 함량의 회복과 MnSOD 및 GPx의 발현 및 활성을 보존과 연관성이 있었다. 비록 EECJ에 함유된 활성 성분의 분석과 in vivo 동물 모델에서의 검증이 요구되지만, 본 연구의 결과는 EECJ가 산화적 스트레스로 인한 간세포의 손상을 예방하고 치료하기 위한 잠재적인 후보로 사용될 수 있음을 의미한다. The root of Cirsium japonicum var. maackii (Maxim.) has long been used in traditional medicine to prevent the onset and progression of various diseases and has been reported to exert a wide range of physiological effects, including antioxidant activity. However, research on its effects on hepatocytes remains scarce. This study used the human hepatocellular carcinoma HepG2 cell line to investigate the antioxidant activity of ethanol extract of C. japonicum root (EECJ) on hepatocytes. Hydrogen peroxide (H₂O₂) was used to mimic oxidative stress. The results showed that EECJ significantly reverted the decrease in cell viability and suppressed the release of lactate dehydrogenase in HepG2 cells treated with H₂O₂. Moreover, an analysis of changes in cell morphology, flow cytometry, and microtubule-associated protein light chain 3 (LC3) expression showed that EECJ significantly inhibited HepG2 cell autophagy induced by H₂O₂. Furthermore, it attenuated H2O2-induced apoptosis and cell cycle disruption by blocking intracellular reactive oxygen species and mitochondrial superoxide production, indicating strong antioxidant activity. EECJ also restored the decreased levels of intracellular glutathione (GSH) and enhanced the expression and activity of superoxide dismutase and GSH peroxidase in H₂O₂-treated HepG2 cells. Although an analysis of the components contained in EECJ and in vivo validation using animal models are needed, these findings indicate that EECJ is a promising candidate for the prevention and treatment of oxidative stress–induced liver cell damage.
