Objective : Allergic rhinitis(AR) is an inflammation or irritaion of nasal mucosa. Usually, serum cytokine is regarded as one of the most important factors in AR. Coisis semen have been used for the diseases in digestive organs in traditional chinese medicine. Nowaday, there were some studies reported about the effects of coisis semens on serum cytokine. However the results of theses studies were varies, and moreover there was no study which have used AR animal model. Therefore this study is aimed to determine therapeutic effects of coisis semen extract by observing changes of serum cytokine(IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13) with AR animal model. Methods : Thirty BALB/c mice were divided into six groups : Normal group, Control group, sample I, sample II, sample III, sample IV. Except for Normal group, all the mice in other 5 groups were sensitized intraperionealy by 0.1% ovalbumin solution three times at intervals of one week. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin solution three times at intervals of two days. Normal group were used Normal Saline instead of ovalbumin solution. After the first day of study, sample I, sample II, sample III, and sample IV were orally administrated coisis semen extract by 100mg/kg, 200mg/kg, 500mg/kg, and 1g/kg respectively for 28days. Then, the changes of serum IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13 were observed in 6 groups. We used the statistical methods of ANOVA, post hoc by duncun, and Kruskal-Wallis test(p<0.05) Results : There were statistical changes in IgE and TNF-${\alpha}$. But, there were no statistical changes in IL-$1{\beta}$, IL-13 and IFN-${\gamma}$. Conclusions : According to above results, it is supposed that coisis semen extract has not some significant effects on cytokine of AR animal model. There was no evidence for using coisis semen in relieving symptoms of allergic rhinitis.

Objectives The goal of this review was to investigate clinical, experimental and literature studies of Korean medicine on atopic dermatitis (AD) of Korean children in Korean medicine literature, seeking for the better research methods for more effective treatments. Methods Electronic investigations were practiced on AKOP (The Association of Korean Oriental Pediatrics, http://www.akop.or.kr) to collect theses which were published by J Pediatr Korean Med. The key word 'Atopy' was used for searching to ensure that every related thesis was collected. The publication date was limited from 1996 to 2016. The selected literatures were assessed mainly according to distributions of study type, publication year, scale, treatment and its efficacy. Results 55 papers were selected from 59 studies. In these collected 55 related theses, there were 29 experimental studies (52.73%), 18 clinical studies (32.73%), 8 review studies (14.55%). In the 29 experimental studies, there were 20 studies (68.97%) using NC/Nga mouse as subjects. The mite antigen was used to trigger AD by 8 studies (27.59%). The studies have been utilizing DNCB and DNFB instead of mite antigen since 2011. All the experimental studies showed that the Korean medicine was effective in AD. In total 18 clinical studies, 3 studies (16.67%) were case reports, only 1 thesis (5.56%) was conducted by case control study and the rest were case series studies. 7 studies (38.89%) of 18 studies diagnosed AD according to Hanifin and Rajka's diagnostic criteria (1980), only 1 study (5.56%) according to the Korean standard and the rest 10 studies (55.56%) didn't mention diagnostic criteria. 12 clinical studies (66.67%) showed efficacy in treating AD. There were 10 studies (55.56%) only employing internal treatments and 1 thesis (5.56%) didn't mention the exact prescription. Naesowhajungtang-kamibang, Saenghyeoryunbue-um were used 3 times (16.67%) as the internal medicine respectively. 5 theses (27.78%) were combined with acupuncture therapy. Hegu (LI4), Sanyinjiao (SP6) were used in 4 theses, and Taichong (LR3), Quchi (LI11), Zusanli (ST36) in 3 theses. The number of acupoints chosen from The Spleen meridian of Foot-Taiyin was the largest. There were 8 review theses. 2 were about the foreign oriental medicine, 3 were about the external medicine or external treatment methods, and 3 other studies were about severity scoring systems, the methodological study in the latest clinical study, overview for pattern and results of herbal medicine-derived AD clinical researches. Conclusions The experimental studies and clinical studies showed the effectiveness of Korean medicine treatments. However, this study still needs improving by conducting more comparative studies and using better research methods, in order to find more effective treatments to improve clinical efficacy.

Objective : Membranous nephropathy (MN) is one of the most commonest forms of glomerular disease in man and the most frequent cause of the adult idiopathic nephrotic syndrome. Some investigators recommend no treatment, while others propose aggressive therapy, including prednisolone plus an immunosupressant such as chlorambucil or cyclophosphamide. But a more effective way to treat MN is not defined yet. This study was to evaluate the effects of Patriniae Radix extract (PRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. The first group (normal) was injected with saline. The second group (control) was treated with cBSA (10 mg/kg i.p) only. The third group, named PRE-2S0, was treated with cBSA (10 mg/kg i.p) and PRE (250 mg/kg, p.o). The fourth group, PRE-500, was treated with cBSA (10mg/kg i.p) and PRE (500mg/kg, p.o). After cBSA and PRE treatment for 4 weeks, we measured change of body weight, 24hrs proteinuria, serum albumin, total cholesterol, triglyceride, BUN, creatinine, IgG, IgA, IgM, $TNF-\alpha$, $IL-1\beta$, and $IFN-\gamma$ levels and the mRNA expression of $IFN-\gamma$, IL-6, and IL-10. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria and serum triglyceride. BUN. IgG. $TNF-\alpha$, and $IL-1\beta$ significantly decreased in both PRE groups, while the level of serum albumin significantly increased in both PRE groups. The mRNA expression of IL-10 in splenocytes considerably increased in both PRE groups. The mRNA expression of $IFN-\gamma$ and IL-6 in splenocytes considerably increased in both PRE group. In histological findings of kidney tissue, thickening of GBM decreased in both PRE groups. Conclusions : The present study suggests that PRE is effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

The analysis of membrane receptors for hormones and neurotransmitters has progressed considerably by pharmacological and biochemical means and more recently through the use of specific antibodies. To generate and characterize a moloclonal antibody against $\beta$-adrenergic receptor, a synthetic $\beta$2-adrenergic receptor peptide (Phe-Gly-Asn-Phe-Trp-Cys-Phe-Trp-Thr-Ser-lle-Asp-Val-Leu) which may comprise part of $\beta$-adrenergic receptor ligand binding pocket was coupled to Keyhole Limpet Hemocyanin (KLH) and used as an immunogen. Male BALB/C mice were immunized with this antigen and the immunized spleen was fused with myeloma SP2/0-Ag14 cells to produce monoclonal antibodies. Two clones were obtained but one of monoclonal antibodies, mAb5G09, was used throughout in this study because the other clone, mAb5All showed weak immunoreactivity against KLH as well. The mouse monoclonal antibody mAb5G09 produced in this study showed immunoreactivity to peptide-KLH conjugates and also to human A43l cells and guinea pig lung $\beta$2-adrenergic receptor as revealed by ELISA and western blot. In the course of determination of the effects of mAb5G09 on $\beta$-receptor ligand binding, it was observed that mAb5G09 specifically bound $\beta$-adrenergic radioligand [$^3$H]dihydroalprenolol (DHA) with a dissociation constant (Kd) of 60 nM. The [$^3$H]DHA binding activity of mAb5G09 had characteristics of immunoglobulins and the binding activity was not observed in the control anti-KLH monoclonal antibody. The monoclonal antibody, mAb5G09 produced in this study may provide useful models for the study of the structure of receptor binding sites.

Objective: This study is aimed to investigate the anti-tumor metastasis by innate immunomodulating effects of crude polysaccharide isolated from Polygonati Rhizoma (CP-PR) on 4T1 breast cancer cells. Methods: CP-PR was isolated from Polygonati Rhizoma. Antimetastatic experiments were conducted in vivo mouse model by using 4T1 breast cancer cells. The cell viability of CP-PR was tested with normal spleen and 4T1 breast cancer cells. To observe the activation of macrophages with/without 4T1 breast cancer cells, production of tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$), interleukin-6 (IL-6), IL-10 and IL-12 were measured with enzyme-linked immunosorbent assay (ELISA), respectively. In addition, the lysis of YAC-1 cells and the production of granzymes were measured to observe the activation of natural killer (NK) cell. Results: Intravenous administration of CP-PR significantly inhibited metastasis of 4T1 breast cancer cells. In an in vitro cytotoxicity analysis, CP-PR affected the growth of normal spleen and 4T1 breast cancer cells above specific concentration. The production of $TNF-{\alpha}$, IL-6, IL-10 and IL-12 were significantly increased in macrophages with CP-PR. As compared with control, CP-PR showed significantly higher production of $TNF-{\alpha}$, IL-10 and IL-12 in macrophages co-cultured with 4T1 breast cancer cells. The lysis of YAC-1 cells and the production of granzymes were significantly up regulated by CP-PR. Conclusion: CP-PR appears to have considerable activity on the anti-metastasis by activation of innate immune system.

Yangkyuksanhwa-Tang (YKSH), consisting of nine different herbs, is commonly used in Soyangin-type individuals with stroke, based on the Sasang Constitution Theory in Korea. However, no evidence has yet confirmed a beneficial effect of YKSH in ischemic stroke treatment. In this study, we investigated the effects of YKSH on ischemic brain injury in a mouse model of cerebral ischemia. Focal cerebral ischemia in mice was induced by photothrombosis, and behavioral recovery was evaluated. Infarct volume, inflammation, and newly generated cells were evaluated by histology and immunochemistry. YKSH treatment resulted in a significant recovery from the motor impairments induced by focal cerebral ischemia, as determined with wire grip and rotarod tests. YKSH treatment also decreased the infarct volume and the number of cells positive for tumor necrosis factor-${\alpha}$ and myeloperoxidase when compared with a vehicle-treated control group. By contrast, YKSH treatment considerably increased the number of cells positive for glial fibrillary acidic protein and ionized calcium-binding adapter molecule 1, as well as the number of cells doubly positive for Ki67/doublecortin when compared with the vehicle-treated group. These results suggest that YKSH treatment attenuated the infarct size by anti-inflammatory action, astrocyte and microglia activation, and neuronal proliferation, thereby facilitating neurofunctional recovery from a cerebral ischemic assault. YKSH could therefore be a potential treatment for neurofunctional restoration of the injured brains of patients with stroke.

The in vitro antioxidant activities and neuronal cell protective effects of 60% (w/v) methanolic extract from Houttuynia cordata were investigated. The contents of total phenolics and quercitrin in the extract were 17.71 mg/g and 75.80 ${\mu}g$/g, respectively. DPPH and ABTS radical-scavenging activities were 87.79% and 99.27%, respectively, when the extract was tested at 5 mg/ml. The FRAP (ferric reducing/antioxidant power) assay showed a dose-dependent increse in activity. In a cell viability assay using MTT, the extract protected against $H_2O_2$-induced neurotoxicity. Lactate dehydrogenase (LDH) leakage was also inhibited by the extract, as was lipid peroxidation as shown using the mouse brain homogenate test. These data indicate that a 60% (w/v) methanolic extract of Houttuynia cordata has in vitro antioxidant activities, and ingestion there of may reduce the risk of developing neurodegenerative disorders.

In this study, we investigated whether the combined administration of berberine (BBR) and silibinin (SBN) was effective in improving hyperlipidemia and anti-obesity efficacy using a high-fat diet (HFD)-fed obese mouse model. HFD-induced obese mice were supplemented with the BBR and SBN combination (BBR-SBN) along with the HFD administration for 8 weeks. During the experiment, body weight, food intake, and levels of total cholesterol, triglyceride and high-density lipoprotein (HDL)-cholesterol were analyzed. Consumption of HFD in the mice caused rapid increases in body weight and the levels of total cholesterol and triglycerides compared to the normal control (NC) group. However, supplementation of BBR-SBN in these obese mice significantly reduced body weight gain and suppressed the levels of total cholesterol and triglyceride with the increment of HDL cholesterol level. In the HFD-fed group, abdominal fat weight was significantly increased and the adipocytes within the epididymal adipose tissue were found to have expanded sizes compared to the NC group. However, in the BBR-SBN group, the sizes of the adipocytes were comparable to those of the NC group and abdominal fat weight was significantly reduced. Moreover, the deposition of giant vesicular fat cells in liver tissues seen in the HFD-fed group was considerably reduced in the BBR-SBN group. These results suggest that the BBR-SBN combination tends to have synergic potential as an anti-obesity agent by significantly reducing body weight gain as well as lowering serum lipid levels and thus improving anti-obesity efficacy in HFD-induced obese mice.

Objectives We evaluated the improving effects of Taeksa-tang (TST) using 3T3-L1 cells and C57BL/6 mice were fed on a high-fat diet. Methods The anti-radical activities of TST were studied using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The content of total polyphenol was measured using Folin-Ciocalteu reagent, whereas aluminum chloride colorimetric method was used for the content of total flavonoid. Moreover, the factors related to lipid profile and the protein expressions such as 𝛽-oxidation and anti-oxidant enzyme were analyzed using serum and western blotting of 3T3-L1 cells. Additionally, we examined lipolysis through glycerol appearance in mouse adipose tissue. Results TST treatment showed strong free radical scavenging activities with half maximal inhibitory concentration and the presence of a amount of total polyphenol and total flavonoid. TST treatment significantly increased factors related to 𝛽-oxidation such as carnitine palmitoyl transferase-1 and uncoupling protein 2 via the phosphorlyation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK). Moreover, the protein expressions of anti-oxidant enzyme and lipolysis were significantly elevated by TST administration. In addition, TST supplementation lowered serum malondialdehyde, triglyceride, and total cholesterol levels compared with the control group. Taken together, these data suggest that TST treatment regulated lipid parameters via the increase of 𝛽-oxidation by LKB1-AMPK signaling pathway. Conclusions TST may have a potential remedy in the prevention and treatment of obesity. Therefore, this study may provide the scientific basis for TST use.

Colibacillosis is one of the major health problems in young piglets resulting in poor health and death caused by Escherichia coli producing F18 pili and Shiga toxin 2e. It is pivotal to reduce colibacillosis in weaned piglets to enhance production performance. In this study, we evaluated synbiotics as the gut health improvement agents in the mouse model challenged with Shiga toxin-producing E. coli (STEC) isolated from piglets. Prebiotic lactulose was formulated with each $5.0{\times}10^6CFU/mL$ of Pediococcus acidilactici GB-U15, Lactobacillus plantarum GB-U17, and Lactobacillus plantarum GB 1-3 to produce 3 combinations of synbiotics. A total of 40 three weeks old BALB/c mice were randomly assigned to 4 groups (n = 10): a control group and 3 synbiotics treated groups. Each treatment groups were daily administrated with $5.0{\times}10^6CFU/mL$ of one synbiotics for the first week, and every 3 days during the second week. All the mice were challenged with $8.0{\times}10^8CFU/mL$ of STEC 5 days after animals began to receive synbiotics. Mice treated with synbiotics based on Pediococcus acidilactici GB-U15 and Lactobacillus plantarum GB-U17 significantly improved daily weight gain compared to mice in other groups. While mice treated with GB-U15 showed better fecal index, no significant differences were observed among groups. Gross lesion and histopathological evaluations showed that mice treated with GB-U15 moderately improved recovery from STEC infection. In conclusion, our results suggest that the synbiotics formulated with lactulose and Pediococcus acidilactici GB-U15 have potential benefits to prevent and improve colibacillosis in weaned piglets.
