The pistil of nelumbo nucifera (PNN) is used in the treatment of nocturnal pollution, hematemesis, epistaxis, metrorrhagia and diarrhoea in traditional medicine. The present study was examined to evaluate the effects of PNN on the production of pro-inflammatory mediators in vitro. After the treatment of PNN, cell viability was measured by MTT assay, nitric oxide (NO) production was monitored by measuring the nitrite content in culture medium. The protein bands were determined by immunoblot analysis and levels of cytokines were analyzed by sandwich immunoassays. In the MTT assay, the doses of PNN extract (0.03, 0.10 mg/ml) had no significant cytotoxicity. The increases of NO production and inducible nitric oxide synthase expression were detected in lipopolysaccharide(LPS)-activated Raw 264.7 cells compared with control, in contrast, these increases were significantly attenuated by pre-treatment with PNN. In cytokine assay, the massive pro-inflammatory cytokines such as tumour necrosis factor-$\alpha$, interleukin (IL)-$1{\beta}$ and IL-6 were induced in LPS-activated Raw 264.7 cells, but pre-treatment of Raw 264.7 cells with PNN caused inhibition (TNF-$\alpha$=14.17%, IL-$1{\beta}$=107.43%, IL-6=46.27%) the production of cytokines by LPS. In addition, PNN reduced prostaglandin E2 productions in a dose-dependent manner (0.03mg/ml=37.52%, 0.10 mg/ml=83.77%) as a consequence of the inhibition of cyclooxygenase-2 expression. Taken together, our data indicates that PNN can regulate the inflammatory response in macrophage cells activated by Gram-negative infection.

This case study reports the effects of complex Korean medicine treatment, including Nangan-jeon, on Lambert-Eaton myasthenic syndrome (LEMS) accompanied by chronic constipation and abdominal pain as the main symptoms. A 39-year-old woman diagnosed with LEMS with major symptoms, including chronic constipation and acute abdominal pain, received Western treatment. The treatment efficacy was weak and symptoms recurred, so the patient received outpatient treatment and 13 days of hospitalization for active Korean medicine treatment, including Nangan-jeon. During outpatient treatment and hospitalization, defecation frequency and the numeric rating scale (NRS) for abdominal pain and abdominal cold feeling were measured. The NRS for abdominal pain and cold decreased from 8 at admission to 3 and 0, respectively, at discharge. Defecation frequency increased significantly from once or twice a month to once every 2-3 days during hospitalization. This study results that complex Korean medicine treatment, including Nangan-jeon may be useful for treating patients who mainly complain of autonomic neurological symptoms, among patients diagnosed with LEMS. In addition, it is believed that it could be basic data applicable to more LEMS patient treatment cases.

Objectives : This study was intended to understand characteristics of symptoms, oriental medicine prescription and laboratory test results according to elapsed time of stroke. Methods : Through the medical records of 205 stroke inpatients in the oriental medical hospital in the year 2010, we investigated manifested symptoms, administered oriental medicine prescription and clinical pathological examination results. Collected items were classified to depend on stroke types, cerebral infarction and hemorrhage. We analyzed association between manifested symptoms, the oriental medicine prescription, and laboratory test results of stroke patients and elapsed time. Chi-square tests were performed to determine the significance level of association. Results : All symptoms, prescriptions and laboratory test results in cerebral infarction patients were associated with elapsed time. Especially, symptoms, prescriptions and pathological examination results showed very high statistical significance with elapsed time (a symptom; chi-square(df)=164.3(22), p<0.001, prescription; chi-square(df)=93.5(22), p<0.001, and pathological examination results; chi-square(df)=164.3(22), p<0.0004). But in the case of cerebral hemorrhage, there was not statistical significance. Conclusions : The elapsed time of stroke may be an essential requisite in catching symptoms and prescribing for stroke patients in oriental medical treatment.

Jo, Mi-Jeong,Lee, Byung-Wook,Eom, Dong-Myung,Lee, Jong-Rok,Hwangbo, Min,Jee, Seon-Young,Kim, Sang-Chan The Korean Medicine Society for the Herbal Formula 2007 大韓韓醫學方劑學會誌 Vol.15 No.1

This study was conducted to evaluate the inhibitory effects of Yongseollan(YSL) on the production of nitric oxide (NO) and the expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-activated RAW264.7 cells. YSL is tropical plant originating from Mexico. The biological activity of this plant is not yet evaluated systematically. The aim of the present work is to investigate a potential anti-inflammatory activity of YSL. The RAW264.7 cells were cultured in D MEM/F12 medium for 24 hrs. After serum starvation, cells were treated with YSL for 1 hr, followed by stimulating NO production with a LPS. We found that YSL has an inhibitory effect on the production of NO, iNOS expression and $phospho-I{\kappa}B$ expression. YSL also inhibited tumor necrosis factor $(TNF)-{\alpha}$, interleukin (IL)-6, and $IL-1{\beta}$. Moreover, YSL inhibited cyclooxygenase (COX)-2 expression and prostanglandin E2 (PGE2). These findings showed that YSL could have some anti-inflammatory effects which might play a role in therapy in Gram-negative bacterial infections.

Effect of Aqueous Extract of Schizandra chinensis and Evodia rutaecarpa Fruits on Experimental Mouse Colitis Induced by Dextran Sulfate Sodium

Jang, Seon-Il,Jeong, Seung-Il,Ryu, Il-Hwan,Kwon, Tae-Oh,Lee, Kang-Soo,Yun, Young-Gab The Korean Medicine Society for the Herbal Formula 2008 大韓韓醫學方劑學會誌 Vol.16 No.2

The aqueous extract of Schisandra chinensis, Evodia rutaecarpa and meal (SEM-Ex) has been traditionally used in the Oriental countries as an astringent. However, little is known about the effects of aqueous extract of SEM-Ex on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SEM-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SEM-Ex was orally administered from day 2 of DSS treatment in the different dose (10-50 mg/kg body weight). SEM-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. Moreover, SEM-Ex suppressed significantly not only the serum haptoglobin levels and the activities of myeloperoxidase (MPO), but also the colon tissue expression levels of monocyte chemoattractant protein-1 (MCP-1) in DSS-induced mice. In contrast, SEM-Ex increased significantly the colon tissue expression levels of granular colony stimulating factor (G-CSF) well known as anti-inflammatory cytokine. These results suggest that SEM-Ex administration could reduce significantly the clinical signs and regulate of chemokine and anti-inflammatory cytokine in DSS-induced model mice. Therefore, these properties may contribute to the strong anti-ulcerative colitis (UC) response effect of SEM-Ex.

Acetaminophen은 세계적으로 널리 사용되는 해열 진통제이지만, 또한 과용 및 남용, 알코올 중독과 같은 여러 원인에 의해 간독성을 유발할 수 있는 약물이다. 이러한 acetaminophen의 간독성은 CYP에 의해 생성되는 대사산물인 NAPQI와 활성산소에 의해 유발되는 것으로 알려져 있다. 본 연구에서 5주된 수컷 백서에 acetaminophen (500 mg/kg)을 투여하기 전에 대시호탕 (500 mg/kg)를 일주일간 투여하였다. 이후 GOT, GPT, GST 그리고, 조직사진으로 대시호탕의 간보호작용을 측정하였다. 또한 대시호탕의 간보호작용 기전을 항산화작용과 CYP 2E1 발현조절을 통한 NAPQI 생성억제의 두 가지 면에서 측정하였다. GOT, GPT 그리고 조직사진에서 나타난 결과들은 대시호탕이 고용량의 acetaminophen에 대한 간보호작용이 있음을 증명할 수 있었다. 또한 LPO와 catalase, 그리고 GSH 실험에서 나타난 결과들을 통해 대시호탕이 항산화작용이 있음을 알 수 있었다. 그리고 GSH, GST, RT-PCR, western blot 실험에서 대시호탕이 CYP 2E1의 발현을 조절하여 NAPQI 생성을 억제한다는 것도 알 수 있었다. 이상의 결과들을 바탕으로 대시호탕은 항산화작용에 의한 활성산소 제거력과 CYP 2E1의 발현조절을 통한 NAPQI 생성억제로 고용량 acetaminophen에 의해 유도된 간손상에 대해 유의성 있는 보호작용을 한다는 것을 알 수 있었다.

Effects of Aqueous Extract of Schizandrae Fructus on Lead-Induced Change of Monoamine Neurotransmitters in Hippocampus

Zhao, Rong Jie,Zhao, Zheng Lin,Zhao, Xiu Feng,Zhao, Guang Wen,Li, Meng Quan,Wu, Yi Yan,Li, Jing Qiu,Guan, Li Xin,Kim, Sang-Chan The Korean Medicine Society for the Herbal Formula 2009 大韓韓醫學方劑學會誌 Vol.17 No.2

The effects of aqueous extract of Schizandrae Fructus (AESC) on lead (Pb)-induced changes of monoamine neurotransmitters in the hippocampus (HIP) of adult rats were investigated. Male Sprague-Dawley rats were received intraperitoneal (i.p.) administration of Pb acetate (5 mg/kg/d) for 28 days and sacrificed 7 days after the last administration. Concentrations of norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxyindole acetic acid (5-HIAA) in HIP were measured by HPLC. There were significant decreases of NE, DA, 5-HT and 5-HIAA in Pb treated rats (P < 0.05), while pretreatment with AESC (100 mg/kg/d or 300 mg/kg/d, p.o., 2 h before Pb) greatly inhibited the decrease of monoamine transmitters, respectively (P < 0.05). Also, AESC (300 mg/kg/d) significantly increased the reduction of glutathione contents and superoxide dismutase activities in HIP induced by chronic Pb. These results suggest that AESC ameliorates Pb-induced depletion of monoamine neurotransmitters in HIP through its antioxidant activity.

김정훈,이나리,신현규,서창섭,Kim, Jung-Hoon,Lee, Nari,Shin, Hyeun-Kyoo,Seo, Chang-Seob The Korean Medicine Society for the Herbal Formula 2014 大韓韓醫學方劑學會誌 Vol.22 No.2

Objectives : Gwakhyangjeonggi-san (GJS) which consists of 13 herbal medicines has been used to treat gastrointestinal disorders caused by common cold. This study was performed to compare GJS decoctions produced using different pressure levels for various extraction times. Methods : Decoctions were prepared by the pressure levels of $0kgf/cm^2$ (non-pressurized) or $1kgf/cm^2$ (pressurized) for 30-180 min. The extraction yield, total soluble solid content (TSSC), and hydrogen ion concentration (pH) were measured, and the contents of the nine marker compounds were determined using high performance liquid chromatography. Results : The higher pressure and longer extraction time significantly increased TSSC value, while decreased the pH value. However, only extraction time affected the extraction yield of pressurized decoction. Variation of the amounts of chemical compounds was shown in pressurized and non-pressurized decoctions during extraction time. The result of regression analysis showed that pressure and extraction time can influence to extraction yield, TSSC, pH, and the content of chemical compounds. Conclusions : This study suggests that the pressure and extraction time can significantly affect the extraction efficiency of components from GJS decoctions.
