Purpose: Paeonia Radix Alba is a traditional herbal medicine used to treat the liver and the spleen. Many studies have reported that Paeonia Radix Alba extract (PR) affects liver injury, but there has been no study on liver injuries induced by thioacetamide (TAA). Therefore, we aimed at evaluating the effect of PR on a TAA-induced acute liver injury (ALI) model. Methods: The antioxidant activity of PR was assayed by the content of total polyphenol, total flavonoid, 1,1-diphenyl-2'-picrylhydrazyl (DPPH), and 2,2'-azino-bis (3-ethylbenzo-thiazoline-6-sulfonicacid) (ABTS) radical scavenging activities in vitro test. ALI was induced via-intraperitoneal injection of TAA (200 mg/kg body weight) for three consecutive days. Also, silymarin (100 mg/kg body weight) and PR (100 or 200 mg/kg body weight) were administered at 1 hours 30 minutes prior to TAA treatment. The levels of ammonia, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) were analyzed using an assay kit. The expressions of antioxidant proteins including Nrf2, Keap1, HO-1, SOD, catalase, and GPx-1/2 and oxidative stress-related proteins including NOX2, p47^phox, and p22^phox were evaluated by the western blot analysis. Results: PR showed excellent antioxidant activity in vitro. TAA administration increased the levels of ammonia, GOT, and GPT in the ALI control group compared to the normal group, whereas it was significantly reduced by PR pretreatment. Moreover, NADPH oxidase protein expressions were upregulated after TAA treatment, while the elevated expressions were inhibited by PR pretreatment. The expressions of antioxidant protein were downregulated in the ALI control group, whereas Nrf2 activation in the PR group was accompanied by increased levels of antioxidant enzymes. Conclusion: PR administration increased the antioxidant enzymes via activation of the Keap1/Nrf2 pathway and inhibited the protein levels of NADPH oxidase factors. Taken together, these results showed that PR treatment may be considered to ameliorate acute liver injury induced by TAA.

Objectives Myopia has a higher prevalence rate in eastern countries, which also have a higher rate of educational fever compared to western countries. Considering this, social costs paid for myopia will increase rapidly in Korea. Although the development of myopia treatment is necessary, there has been a lack of relevant studies. Thus, this study aims to produce data to prevent unnecessary treatments and medical expenses. Methods The objective is to evaluate the effect of periocular acupressure exerted by a medical massager for myopia. This is an open-label, prospective, single-arm, and pre and post superiority study. The subjects are 7~12-year-old myopia patients with under 5 D (diopter) of spherical equivalent. A total of 56 subjects were enrolled. The selected subjects will wear the massager for 15 minutes twice a day for 24 weeks. The primary endpoint is the refraction change. The secondary endpoint is the axial length change. Statistical analysis was performed at a significant level of 0.05, using a two-tailed test. The criterion for significantly improved refraction was $-0.17{\pm}0.50$ D/6 months and that of axial length change was 0.126 mm. Results and Conclusions This study did not include a control group because children represent a vulnerable group. This objective study will bring some impact on Korean medical myopia treatment. A long-term confirmatory clinical study may be necessary in future.

Conventional medicines have usually sorted to a number of treatments such asoperation, radiotherapy, and chemotherapy. The existing anti-cancer agents, designed to eradicate cancer cells, have strong toxicities, also with leading to harmful side effects. Recently, a number of researches on natural products have been actively carried out in efforts to develop new treatments that can decrease side effects or increase anti-cancer effects. We performed this study to understand the molecular basis underlying the antitumor effects of Pharbitis nil, and Plantago asiatica, which have been used for herbal medicinal treatments against cancers in East Asia. We analyzed the effects of these medicinal herbs on proliferation and on expression of cell growth/apoptosis related molecules, with using an AGS gastric cancer cell line. The treatment of Pharbitis nil dramatically reduced cell viabilities in a dose and time-dependent manner, but Plantago asiatica didn't. FACS analysis and Annexin V staining assay also showed that Pharbitis nil induce apoptotic cell death of AGS. Expression analyses via RT-PCR and Western blots revealed that Pharbitis nil didn't increase expression of the p53 and its downstream effector p21/sup wafl/, and that the both increased expression of apoptosis related Sax and cleavage of active caspase-3 protein. We also confirmed the translocation of Sax to mitochondria. Collectively, our data demonstrate that Pharbitis nilinduce growth inhibition and apoptosis of human gastric cancer cells, and these effects are correlated with down- and up-regulation of growth-regulating apoptotic and tumor suppressor genes, respectively.

Objectives: The aim of this investigation was to evaluate the efficacy of KHchunggan-tang aqueous extract on the experimental nonalcoholic fatty liver disease(NAFLD) induced by palmitate. Materials and Methods: To generate a cellular model of NAFLD, we used HepG2 cells, a human hepatoma cell line, treated with 0.5 mM palmitate. By this cellular model, effects of KHchunggan-tang aqueous extract were evaluated. Intracellular lipid accumulation, free radical formation, and apoptosis were detected by Nile red staining, 2',7'-dichloroflourescin diacetate(H2DCF-DA), and 4',6-diamidino-2-phenylindole(DAPI)/propidium iodide(PI) staining, respectively. Some proteins related with NAFLD were determined by western blot. Results: Typical pathological features of NAFLD occurred in the cellular model. Palmitate increased the levels of intracellular lipid vacuoles, decreased cell viability, and increased apoptosis. Palmitate increased free radical formation and lipid peroxidation, too. However, KHchunggan-tang aqueous extract reduced palmitate-induced pathologic features, i.e. steatosis, free radical formation, and apoptosis. In addition, KHchunggan-tang aqueous extract suppressed palmitate-activated c-Jun N-terminal kinase(JNK) signaling, and SP600125, a JNK inhibitor, significantly reversed the palmitate-induced pathologic changes as KHchunggan-tang aqueous extract. It means that the signaling pathway other than JNK can be involved in the KHchunggan-tang mediated cellular protection of palmitate-treated Hep G2 cells. Conclusions: These results suggest that KHchunggan-tang aqueous extract has hepatoprotective effects on NAFLD with combined properties in cellular steatosis, ROS production, and cytoprotection, and thus may have valuable clinical applications for treatment of this chronic liver disease.

Objectives The purpose of this study is to provide clinical evidence of Korean medicine for febrile seizure by review of randomized controlled trials on the effect of TCM (traditional Chinese medicine) for febrile seizure. Methods We searched randomized controlled trials about TCM treatment of febrile seizure from the China National Knowledge Infrastructure (CNKI) (January 2008 to June 2016). The selected literatures were assessed by Jadad scale. Results 40 papers were selected from 160 studies. Analyses of selected studies indicated that the TCM treatment group has significantly higher cure rate for febrile seizure than first aid or western medicine group. The most commonly used herbs were Gardeniae Fructus (梔子), Uncariae Ramulus cum Uncis (鉤藤), Cornus Gazeliae (羚羊角), Margarita (珍珠), Scutellariae Radix (黃芩), Glycyrrhizae Radix (甘草). The most commonly used acupoints were GV26 (人中), LI4 (合谷), KI1 (湧泉), GV20 (百會). There were no serious adverse events reported from the TCM treatment group during the treatment period. Conclusions TCM has been shown as not only effective but also safe treatment on febrile seizure. This finding can be widely utilized in clinical practice and can form the basis for development of clinical practice guidelines in future.

Objectives The purpose of this study was to compare the effects of acupuncture treatment with those of collaborative treatment regarding acute Bell's palsy. Methods Twenty-six patients who received outpatient treatment between March 2012 and February 2013 were divided into 2 groups. The East-West treatment group (EW group, n=12) received prednisolone and then acupuncture afterwards. The Eastern treatment group (E group, n=14) received just acupuncture. Acupuncture was administered 3 to 4 times a week, and both groups were educated to practice facial muscle exercises at home. Evaluations were made before treatment, after 1 week, 2 weeks, and 3 weeks using the House-Brackmann facial nerve grading system. Results Compared to before treatment, the House-Brackmann grades of both EW and E groups after 1, 2 and 3 weeks of treatment significantly decreased (p<0.05). Regarding group comparison, the House-Brackmann grade of the EW group was significantly lower than the E group at 1 week (p=0.043), but there was no significant difference at 2 and 3 weeks. Regarding improvement of House-Brackmann grades, there was no significant difference between the two groups at 1, 2 and 3 weeks (p>0.05). Conclusions Compared to just acupuncture treatment, collaborative treatment with prednisolone significantly improved the House-Brackmann grade after 1 week, but there was no difference as time passed. Because early intervention determines the prognosis of Bell's palsy, collaborative treatment at the early stage will be clinically helpful to patients.

Background: Recent studies have shown that Korean Red Ginseng (KRG) successfully protects against dopaminergic neuronal death in the nigrostriatal pathway of a Parkinson's disease (PD) mouse model induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration; however, the mechanism has yet to be identified. Therefore, in this study we used two-dimensional electrophoresis to investigate the effects of KRG on the changes in protein expression in the substantia nigra (SN) of MPTP-treated mice. Methods: Male C57BL/6 mice (9 wk old) were intraperitoneally administered MPTP (20 mg/kg) four times at 2-h intervals, after which KRG (100 mg/kg) was orally administered once a day for 5 d. Two hours after the fifth KRG administration, a pole test was conducted to evaluate motor function, after which the brains were immediately collected. Survival of dopaminergic neurons was measured by immunohistochemistry, and protein expression was measured by two-dimensional electrophoresis and Western blotting. Results: KRG alleviated MPTP-induced behavioral dysfunction and neuronal toxicity in the SN. Additionally, the expression of eight proteins related to neuronal formation and energy metabolism for survival were shown to have changed significantly in response to MPTP treatment or KRG administration. KRG alleviated the downregulated protein expression following MPTP administration, indicating that it may enhance neuronal development and survival in the SN of MPTP-treated mice. Conclusion: These findings indicate that KRG may have therapeutic potential for the treatment of patients with PD.

This case report highlights the efficacy of traditional Korean medicine in treating chronic levator ani syndrome. A 47-year-old male suffered from chronic anorectal pain for 14 years. Over the last 5 months, the severity and frequency of the pain increased, and he was unresponsive to Western medicine and acupuncture outside Korea. The patient reported moderate anorectal pain from early morning until midday, affecting daily efficiency and concentration. The pain was triggered by defecation and alleviated by lying down. He was diagnosed with levator ani syndrome related to "cold symptoms of the liver and kidney - Yin", for which modified Nangan-jeon was prescribed. Indirect moxibustion (CV4, Ki1), Aconitum ciliare Decaisne pharmacopuncture (GV1, BL33), and acupuncture (HT7, ST36, SP6, LR3, LI4) were also administered weekly. After 8 weeks, the anorectal pain decreased by 2 points on a numeric rating scale, leading to patient satisfaction and return to his home country.

Overview: The purpose of this study was to evaluate the determinants on the correlation between constitution and health promoting lifestyle profile on the workers. Also, the questionnaire on the HPLP (health promoting lifestyle profile) of Walker(1987) and Sa-sang constitution of Lee(l894) were utilized Methods: Data from a representative sample of 652 workers were analyzed Pearson's chi-square test analysis was utilized to test the explanatory causal model and to determine the direct and indirect effects of independent variables on quality of life. Results: Constitutional distribution among exposed group, were Tae-eum In(43.7%), So-eum In(33.6%), and So-yang In(22.7%). The degree of the subjects practicing health promoting lifestyle, on a scale of 1 to 4, is an average of 2.62, personal relations 2.94, self-realization 2.86, stress management 2.71, nutrition 2.68, responsibility for health 2.37, and exercise 2.21, with personal relations earning the highest points and exercise the lowest As for factors influencing health promoting lifestyle, there is significant difference between sex and age. That is female and higher age. On the difference between constitution and health promoting lifestyle, Tae-eum In is the highest all area except personal relations. So-eum In is the lowest all area except responsibility for health. Conclusions: Tae-eum In totally do health promoting lifestyle well but So-eum In relatively not. On the Study we used the HPLP(health promoting lifestyle profile) on the premise that each person's daily life, the attitude and the practice level to the health have an influence on the health. So in the constitution there is a little differences in the consideration and the practice level and health condition will be different. On this study we finish up by knowing about the health promoting lifestyle. But on next time we will have to go on studying about the sign and the comparison with the result of western and oriental medical health examination to the each constitution on carrying out continuously oriental medical health examination.
