  • Obesity has increased dramatically increased in recent days. It has resulted in obesity-associated diseases and metabolic syndromes including hyperlipidemia, diabetes and cardiovascular diseases. Our study was investigated to determine the antiobese effects of mixed 2 medicinal herbs (AR+AC) in rats fed high-fat diet with an abundance of carbohydrates. Two groups of male Sprague-Dawley rats were fed different diets during 8 weeks: normal diet containing 5% corn oil (w/w), high-fat diet containing 10% (w/w) lard plus 5% (w/w) corn oil (HF). And High-fat diet group was treated with saline or 100 mg/kg ARAC or 300 mg/kg ARAC (PO). Antiobese effect was evaluated by measuring the changes of body weight, adipose tissues weight. Also we examined levels of leptin, adiponectin and lipid profiles in serum. Finally we compared morphological change in adipocytes and hepatocytes between HF and ARAC group. Mixed combination of 2 medicinal herbs, but not alone, caused significant decrease in body weight, organ weight (liver, epididymal fat, and BAT) compared with control HF group. The ARAC group had markedly lower serum levels of adiponectin when compared with HF group. Also the epididymal white adipocyte size of ARAC group were diminished comparing to the HF group. These results suggest that the possibility of ARAC combination, as an antiobese formula, by suppression of body weight gain and increased lipid profiles.

  • Puerariae radix (PR) is a popular natural herb and a traditional food in Asia, which has antithrombotic and anti-allergic properties and stimulates estrogenic activity. One of the major side effects of cisplatin is nephrotoxicity, leading to acute renal failure. Recent study has suggested a role of ROS and p53 in renal cell injury by cisplatin. We studied that protective effects of PR on cisplatin-induced apoptosis in rat mesangial cell. Rat mesangial cell was preincubated with PR (50, 100, 150 and 200 ${\mu}g/m{\ell}$) for 12 hr and then treated with 30 ${\mu}M$ cisplatin for 24 hr. Protective effect of PR on cisplatin-induced apoptosis in ECV304 cells was determined using MTT assay, FDA-PI staining, flow cytometric analysis, caspase-3 activity assay, ROS assay and western blot. Our results showed that PR inhibited in cisplatin-induced apoptosis and ROS production in ECV304 cells. Moreover, PR reduced ERK, p38 and JNK activation that increased in cisplatin-treated rat mesangial cell. Furthermore, activation of p53 by cisplatin in rat mesangial cell was inhibited by PR treatment. These results suggest that protective effect of PR on cisplatin-induced apoptosis in rat mesangial cell may be associated with reduction of ERK, p38, JNK, p53 activation.

  • Isolating total DNA from small samples using traditional methods is difficult and inefficient mainly due to loss of DNA during filtration and precipitation. With advances in molecular pathology, DNA extraction from micro-dissected cells has become essential in handling clinical samples. Genomic DNA extraction using small numbers of cells can be very important to successfully PCR amplify DNA from small biopsy specimens. We compared our experimental genomic DNA extraction method (A) with two other commercially available methods: using spin columns (B), and conventional resins (C), and determined the efficacy of DNA extraction from small numbers of cells smeared on a glass slide. Approximately 50, 100, 200, 500 and 1000 cells were isolated from fine needle aspiration biopsy (FNAB) slides aspirated from histologically proven papillary thyroid carcinoma masses. DNA was extracted using the three techniques. After measuring DNA quantity, PCR amplification was performed to detect the ${\beta}$-globin and $BRAF^{V600E}$ gene mutations. DNA extracted by method (A) showed better yield than the other methods in all cell groups. With our method, a suitable amount of genomic DNA to produce amplification was extracted from as few as 50 cells, while more than 100 to 200 cells were required when methods (B) or (C) were applied. Our genomic DNA extraction method provides high quality and improved yields for molecular analysis. It will be especially useful for paucicellular clinical samples which molecular pathologists often confront when handling fine needle aspiration cytology, exfoliative cytology and small biopsy specimens.

  • Objectives : Atotang was composed of 10 kinds of traditional medicinal herb. This research was performed to examine biological effects of Atotang for the development of prescription on atopic dermatitis. Methods : Atotang was extracted with 80% EtOH. Free radical scavenging assay has tested for anti-oxidative activity as well as the contents of total polyphenol. We observed the production of ROS, nitric oxide(NO) and the inflammatory cytokines such as interleukin-1beta(IL-${\beta}$), IL-6, tumor necrosis factor-alpha(TNF-${\alpha}$), Prostaglandin E2($PGE_2$) in Raw 264.7 cells stimulated by LPS. We used Disc diffusion method to investigate antibacterial activity on Candida albicans, Staphylococcus aureus and Staphylococcus epidermis. Result : Content of total phenolic compound of Atotang was 36.3 mg/g ext. DPPH and ABTS scavenging activities were 77% and 46% at 200 ug/ml respectively, showing dose-dependent increase. The amounts of ROS and NO in RAW 264.7 cells were decreased by 30% and 19% at 200 ug/ml, respectively, showing dose-dependent decrease. The prodcution of IL-1beta, IL-6 and TNF-alpha in RAW 264.7 cells were decreased dose-dependently by 81%, 67%, and 20% at 200 ug/ml, respectively. Atotang was reduced LPS-stimulated production of $PGE_2$ by 33%. Atotang on C. albicans, S. aureus and S. epidermis was selected by a disc diffusion method and inhibition effect of the Atotang on the growth of S. epidermis was the greatest. Conclusion : The results indicated that Atotang showed biological activities showing anti-oxidant, anti-inflammatory and antibacterial effects. Based on these results, it is concluded that Atotang can be applied to the prescription on atopic dermatitis.

  • Background: There are various Helicobacter species colonizing the stomachs of animals. Although Helicobacter species usually cause asymptomatic infection in the hosts, clinical signs can occur due to gastritis associated with Helicobacter in animals. Among them, Helicobacter pylori is strongly associated with chronic gastritis, gastric ulcers, and gastric cancers. As the standard therapies used to treat H. pylori have proven insufficient, alternative options are needed to prevent and eradicate the diseases associated with this bacterium. Cheonwangbosim-dan (CBD), a traditional herbal formula that is popular in East Asia, has been commonly used for arterial or auricular flutter, neurosis, insomnia, and cardiac malfunction-induced disease. Objectives: The present study investigated the antimicrobial effect of CBD on H. pylori-infected human gastric carcinoma AGS cells and model mice. Methods: AGS cells were infected with H. pylori and treated with a variety of concentrations of CBD or antibiotics. Mice were given 3 oral inoculations with H. pylori and then dosed with CBD (100 or 500 mg/kg) for 4 weeks or with standard antibiotics for 1 week. One week after the last treatment, gastric samples were collected and examined by histopathological analysis, real-time quantitative polymerase chain reaction, and immunoblotting. Results: Our results showed that CBD treatment of AGS cells significantly reduced the H. pylori-induced elevations of interleukin-8, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). In the animal model, CBD treatment inhibited the colonization of H. pylori and the levels of malondialdehyde, inflammation, proinflammatory cytokines, iNOS, and COX-2 in gastric tissues. CBD also decreased the phosphorylation levels of p38 mitogen-activated protein kinase family. Conclusions: This study suggests that CBD might be a prospective candidate for treating H. pylori-induced gastric injury.

  • The seeds of Trichosanthes kirilowii (STK) used in traditional Oriental medicine for the treatment of dry cough and constipation have diverse pharmacological activities, including hypolipidemic, antioxidant, immunosuppressive, and anticancer effects. However, the effect of STK on angiogenesis has not been studied yet. In this study, we investigated whether the ethanolic extract of STK (ESTK) can regulate the migration and tube formation of human umbilical vein endothelial cells (HUVECs) and explored the underlying mechanism. Results of transwell assay showed that ESTK treatment dose-dependently suppressed the migration of HUVECs. The conditioned medium collected from H1299 human lung cancer cells was used as a chemoattractant. Our observation suggests that ESTK would inhibit the recruitment of endothelial cells into tumors. In addition, ESTK treatment significantly reduced the tube formation of HUVECs. As a molecular mechanism, we found that vascular endothelial growth factor (VEGF)-induced phosphorylation of VEGF receptor 2 (VEGFR2) was completely blocked by ESTK treatment. The expression of angiogenic factors, including VEGFA, fibroblast growth factor 2 (FGF2), angiopoietin, placental growth factor (PGF), platelet derived growth factor (PDGF), angiogenin, and tumor necrosis factor (TNF)-α, was commonly decreased by ESTK treatment in H1299 cells, indicating that ESTK would reduce the production of angiogenic factors from cancer cells. Taken together, our results clearly demonstrated that ESTK exhibited anti-angiogenic effects in HUVECs, which provides another possible mechanism underlying the anticancer activities of STK.

  • The aim of this study was to investigate the safety of short-term use of Korean herbal medicine (KHM; prescribed herbal medicine by doctors of traditional Korean medicine) on liver function. Three hundred eighty four outpatients who took KHM for various conditions were enrolled for multi-center, prospective observational study. Of them 237 patients completed questionnaire and were checked liver function (aspartic aminotransferase;AST, alanine aminotransferase;ALT, alkaline phosphatase;ALP, total bilirubin;t-Bil, direct bilirubin;d-Bil, gamma glutamyltranspeptidase;GGT, protein and albumin) before and after taking KHM (duration; 21.4${\pm}$10.0 days), and data were analysed statistically. Of the 213 patients showing normal liver function test (LFT) at baseline, 209 (98.1%) remained within the normal range at the second test while 3 (1.4%) revealed slight increase of LFT. Only one subject had raised LFT regarding level of liver injury without perceived symptoms. Twenty-four of 237 patients were abnormal at baseline, and 16 at the second testing. Of the patients taking KHM, only 4 changed from normal to abnormal while 12 from abnormal to normal in their LFT. There were no significant increase in LFT level between the first and second test, except in the t-Bil level, however, the change of t-Bil was small and within normal range. The current study showed that the use of KHM did not increase the frequency of abnormal LFTs, at least in the short term.

  • The purpose of this study was to review the research on treating depression in Traditional Chinese Medicine(TCM) over the last 5 years to set the foundation for further studies. We searched for and analyzed articles about depression in CNKI(China National Knowledge Infrastructure) from January 2010 to December 2014. The results were as follows : The most frequently used diagnostic criteria was CCMD-3(The Chinese Classification of Mental Disorders-3), and the most used evaluation criteria was HAMD(Hamilton Depression Rating Scale). Prescription of decoction of medical herbs was most frequently used as a therapeutic method. Acupuncture, traditional Chinese psychotherapy, and music therapy were also used for some studies. The most frequent TCM Syndrome Differentiation Type was stagnation of liver-QI. For decoction of Chinese herbs, Soyo-san(Xiaoyao-san) and Sihosogan-san(Chaihushugan-san) were most often prescribed, and Bupleuri Radix, Paeoniae Radix Alba, Curcumae Radix, Poria cocos wolf, Angelicae Gigantis Radix, Atractylodis Rhizoma Alba were mainly used for medical herbs. BaekHoi(GV20) and Yindang(Ex-HN3) were often used as acupuncture sites. Post-Stroke Depression was the most common case of intercurrent or secondary depression. According to the Jadad Quality Assessment Scale, the quality of the reports was not high as most of the reports had a score of 3 or below. Most systematic reviews on depression were conducted by Chinese researchers. The problem with Clinical research on depression, according to those reviews, was that there were no standardized criteria for the diagnosis and treatment and the trials were usually not randomized nor controlled. We found out there are various clinical methods for treating depression in TCM, and hope that this research could provide the preliminary data for designing and conducting clinical trials for depression.
