This study was performed to investigate the medicinal effects of the herbal combination extracts-2 (HCE-2), consisting of Artemisia capillaris Thunb., Lonicera japonica Thunb., Prunella vulgaris var. lilacina, and Hovenia dulcis Thunb. on the alcohol-induced liver injury in rats. The rats were randomly divided into four groups: normal group (n =6), non-treated control group (n =6), saline-treated group (n =6) and the herbal combination extract (HCE-2)-treated group (n =6). The rats in the alcohol-loaded groups were orally administered with ethanol at a daily dose of 4 g/kg-body weight for 5 weeks. Thirty minutes before the ethanol injection, saline or herbal combination extracts was administered by using a gastrogavage. Blood and liver tissue samples were taken out from the hearts and livers of the rats, respectively, on 15th and 38th days. The activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured using an enzyme-linked immunosorbent assay (ELISA). We also investigated the protective effect of the herbal combination extracts by Hematoxylin-Eosin staining on histological sections of rat liver. In this study, the oral administration of the herbal combination extracts significantly reduced the serum levels of AST and ALT, which had been raised by alcohol-induced liver injury. Histological analysis and apparent observation of liver also showed the preventive effect of the herbal combination extracts in a chronic alcohol-induced rat model. Theses results revealed that the herbal combination extracts effectively prevented hepatic damage consequent to the chronic exposure to repetitive administration of ethanol and could be used as a primary resource of a health beverage or herbal medicine, alleviating the alcohol-induced hepatic injury and hangover symptoms.

Objectives: Phthalates are used as plasticizers in polyvinyl chloride (PVC) plastics. As phthalate plasticizers are not chemically bound to the PVC, they can leach, migrate or evaporate into indoor air and atmosphere, foodstuffs, other materials, etc. Therefore, humans are exposed through ingestion, inhalation, and dermal exposure over their entire lifetime, including during intrauterine development. In particular, university students have a great number of opportunities to contact products including phthalates during campus life (food packaging, body care products, cosmetic, lotions, aftershave, perfume etc.). The purpose of this study was to examine levels of phthalate exposure as undergraduate students begin to use pharmaceuticals and personal care products including phthalates. Methods: Phthalate metabolites, mono-ethyl phthalate (MEP), mono-n-butyl phthalate (MnBP), mono-isobutyl phthalate (MiBP), mono-2- ethylhexyl phthalate (MEHP), {(mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP}, and mono-(2-ethlyl-5-oxohexyl) phthalate (MEOHP} were examined. 80 urine samples collected from university students were analyzed using LC/MS/MS(API 4000, Applied Bioscience) with on-line enrichment and columnswitching techniques. This study was carried out at Y university located in Gyonggi Province from 2008 to 2011. Results: The detection limit of phthalate metabolites were 0.03 ng/mL for MEP, 0.11 ng/mL for MnBP, 0.08 ng/mL for MiBP, 0.93 ng/mL for MEHP, 0.19 ng/mL for MEOHP and 0.16ng/mL for MEHHP. MnBP showed the highest urinary levels (median: 31.6 ug/L, 24.8 ug/g creatinine (cr)). Concentrations were also high for MEHHP (median: 24.1 ug/L, 19.0 ug/g cr), followed by MEOHP (median: 22.8 ug/L, 17.9 ug/g cr). In individual cases, the maximum level reached up to 348 ug/L, and 291 ug/g cr, respectively. The urinary and creatinine adjusted levels of MEP were lower than those for DBP and DEHP metabolites, but were higher in 95th percentiles. As a result, the mean daily DEP intake value was 2.3 ${\mu}g/kg$ bw/day, 3.5 ${\mu}g/kg$ bw/day for DEHP and 4.9 ${\mu}g/kg$ bw/day for DBP. Conclusion: These students' phthalate exposure levels were below the international safe level set by the EU, but higher than the 2012 KFDA survey of the age group from 3 to 18.

We investigated the pathogenesis of liver tissue damage during the lipid peroxidation and fibrogenesis with the observation of correlations between the parameters of collagen synthesis (and deposition) and lipid peroxidation in liver fibrosis (cirrhosis) rats. Rats were randomly divided into two groups, normal and $CCl_4$-thiopental sod. intoxicated group. And the one group was treated intragastrically with the mixture of $CCl_4$-thiopental sod. 3 times per week for 3 weeks. The liver tissue and sera were used for the measurement of hydroxyproline (HYP), malonedialdehyde (MDA) and superoxide dismutase (SOD). Biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total-bilirubin and blood urea nitrogen (BUN) were measured. Additionally, the expression of collagen ${\alpha}1$(III) and $\beta$-actin mRNA was observed by RTPCR. The histological change in liver tissue was also observed by Masson's trichrome and H&E staining. Correlation analysis was carried by Spearman's rho method. All biochemical parameters except total-bilirubin were significantly higher in the $CCl_4$-thiopental sod. treated group than that of the normal group (p < 0.01). In the $CCl_4$-thiopental sod. treated group, Hyp as a parameter of collagen synthesis (deposition) and MDA as a metabolite of lipid peroxidation, were significantly elevated by 1.98 and 2.11 times higher than that of the normal group (p < 0.001) respectively. The activity of SOD in the $CCl_4$-thiopental sod. treated group is decreased significantly by 44.8% (p < 0.001). And collagen ${\alpha}1$(III) mRNA was more expressed in the $CCl_4$-thiopental sod. treated group than that of the normal group. However, the expression of $\beta$-actin mRNA is showed similar in both of groups. A good correlation was observed between the content of hyp and MDA concentration (r = 0.70, n = 40) in the two groups. And the correlation between the levels of hyp and SOD (r = -0.71, n = 25) is also reliable. However, no correlation were observed between MDA concentration and SOD (r = -0.40, n = 25) in the two groups. Elevated levels of MDA in $CCl_4$-thiopental sod. treated rats indicated enhancement of lipid peroxidation, which is accompanied by a decrease in SOD activity. Moreover, we could confirm that the parameters of collagen synthesis (and deposition) is in good correlation with the metabolite of lipid peroxidation (MDA) and the lipid peroxidation antagonizing enzyme (SOD). Hence, we propose that (1) lipid peroxidation and collagen synthesis (and deposition) could be enhanced by intragastrically application of $CCl_4$-thiopental sod. during a short terms. And (2) the intoxication of $CCl_4$-thiopental sod. could be used for monitoring of lipid peroxidation and collagen synthesis (and deposition) for test of antioxidant and antifibrotic agent.

카르복시테라피(Carboxytherapy)는 메조테라피(mesotherapy)와 방법, 치료 조건 및 결과 면에서 매우 유사하다. 그러나 중요한 차이점은 카르복시테라피는 이산화탄소 가스를 피부 바로 아래의 피하층으로 주입하는 반면 메조테라피는 비타민, 미네랄, 그리고 약물의 혼합물을 주입한다는 것이다. 메조테라피의 합병증으로 혈종, 파누스육아종, 봉와직염, 농양 등 이전에 많은 사례들이 보고되었으나, 카르복시테라피는 피하 및 얕은층에 이산화탄소를 주입하고, 이산화탄소는 주입 1주일 안에 흡수되기 때문에 부작용이 거의 보고 되지 않았다. 3일전과 2주전에 한의원에서 카르복시테라피를 받은 29세 여자 환자가 고열, 근육통, 심한 요통 및 엉덩이 부위부터 아래쪽 흉벽까지 피하 기종을 주소로 응급실에 내원하였다. 진단 및 치료를 위해 컴퓨터 단층 촬영을 시행하였으며, 즉시 영상의학과에 판단을 의뢰하였다. 바늘에 의한 손상으로 인한 급성 복막염을 배제할 수 없어 즉각적인 광범위항생제를 투여하였으며, 판독 결과 근육염과 바늘 손상으로 인한 신우신염이 확진되었다. 신우 신염의 경우 적절한 치료가 이루어지지 않으면 패혈증까지 진행할 수 있어 치명적인 결과를 초래 할 수 있다. 따라서 만일 바늘에 찔리거나 침을 맞은 후에 환자가 늑골척추부위나 허리에 통증이 있는 경우 응급의학과 의사는 진단 및 치료를 위해 신속한 초기 평가가 필요하다.

Objectives : A root of Dipsacus asperoides C. Y. Cheng et T. M. Ai (D. asperoides) has been traditionally used as a medicinal resource in several Asian countries, including Korean and traditional Chinese medicine that has been traditionally used for treating several medical conditions including pain, arthritis, and bone fractures in Korea. In the present study, we investigated potential subacute toxicities of D. asperoides extract. Methods : C57BL/6 mice (male, 7weeks) were randomly divided into 4 groups of 5 mice. Except for the control group, the mice were orally administrated D. asperoides extract at doses of 50, 150, or 450 mg/kg/day for 2 weeks. At the end of the treatment period, all mice were euthanized, and the following parameters were examined: mortality, body weight, clinical signs, gross findings, hematology, serum biochemistry, organ weight, and histopathology. Results : There were no abnormalities in mortality, clinical signs, body weight, gross findings, or organ weight after repeated administration of D. asperoides extract for 2 weeks, compared with the control group. In addition, there were no significant changes in hematological, serum biochemical, and histopathological parameters between the control group and D. asperoides extract administrated groups with doses of up to 450 mg/kg/day. Conclusion : In this study, D. asperoides extract showed no significant toxicities at a dose of up to 450 mg/kg/day in mice. Although we could not confirm the toxic dose of D. asperoides extract, it can be considered safe for further pharmacological use.

Repeated bouts of ulcerative colitis featured troublesome course of inflammatory bowel disease leading to fatal colitis-associated cancer, which is strongly associated with oxidative stress and sustained inflammation. Since oligonol, low molecular weighted polyphenol extracted from fruit lychee, showed antioxidative and anti-inflammatory actions, we hypothesized that oligonolcan prevent relapse of colitis. We compared oligonol with current gold standard therapeutics, sulfasalazine in preventive efficacy of relapse. First, dextran sulfate sodium (DSS)-induced colitis were made following pretreatment with oligonol, 10, 50, and 100 mg/kg for 7 days to measure therapeutic effect of oligonol and relapse model via repeated DSS administration was made following with either 50 mg/kg oligonol or 30 mg/kg sulfasalazine to explore relapse preventing action of oligonol in C57BL/6 mice. Detailed changes in colon were measured to explain molecular mechanisms. Pretreatment of 10, 50, 100 mg/kg oligonol (p.o.), significantly reduced DSS-induced colitis; total pathologic scores, colon length, and clinical symptom scores (P < 0.05). Oligonol pretreatment significantly decreased the levels of interleukin (IL)-1, IL-6, and tumor necrosis factor-α (TNF-α) as well as nuclear factor-κB (NF-κB), c-Fos, and c-Jun in affected colon tissues, but the expression of heme oxygenase-1 (HO-1) and NADH: quinone oxidoreductase-1(NQO-1) as well as total antioxidant concentration (P < 0.005) was significantly increased with oligonol. A relapse model established with repeated DSS administration led to high mortality. However, oligonol significantly ameliorated exacerbations of colitis, while sulfasalazine did not (P < 0.01). Significantly decreased expressions of cyclooxygenase-2 (COX-2), TNF-α, and macrophages inhibition were relapse preventing actions of oligonal, but significant action of oligonol relevant to relapse prevention was either significantly increased expressions of NQO-1 or significantly preserved mucin (P < 0.05). Concerted anti-inflammatory, antioxidative, and host defense enhancing actions of oligonol can be applied during maintenance therapy of IBD to prevent relapse of IBD.

견우자는 한의학에서 사하 작용 및 이뇨 작용 등의 치료 목적으로 사용되어 왔다. 본 연구에서는 견우자를 methanol로 추출하고(PNM), 이를 기본으로 ethyl acetate 분획물(PNE), butanol 분획물(PNB), water 분획물(PNW)로 나누었으며 각 분획물을 이용하여 mushroom tyrosinase 저해활성, pancreatic lipase 저해활성, DPPH free radical 소거활성 및 암세포주의 증식 저해활성 등을 조사하였다. 특히, 전립선암 세포주 PC-3 세포에서 강력한 세포 증식 저해활성을 보였으며, 용매 분획물 중, butanol 분획에서 가장 높은 암세포의 증식 저해활성을 보였다. 따라서 견우자의 methanol 추출물을 Diaion HP-20 column chromatography, reverse phase column chromatography, Sephadex LH-20 column chromatography를 순차적으로 실시하여 최종적으로 저해활성이 가장 높은 compound PN을 얻었으며 HPLC를 통해 그 순도를 확인하였다. Compound PN을 이용하여 cell cycle arrest과 annexin V/PI를 측정한 결과, 세포의 sub-G1기를 축적되면서 apoptosis가 유발되어 전립선암 세포주 PC-3 세포의 세포사멸이 유도되는 것을 확인하였다. 따라서 본 연구를 통하여 견우자에 대한 항산화 활성, 미백 활성 등의 효과 뿐 만 아니라 항암 활성에도 활용할 수 있을 것으로 사료된다.
