The purpose of the present study was to determine the effect of a 4 week course of Cox distraction manipulation (CDM) combined with therapeutic modalities on the treatment of patients with L4-5 herniated nucleus pulposus (HNP). A total of 15 patients with L4-5 HNP (mean age, 37.76 years; age range 20-50years) participated in the study. A 4 week course of CDM combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and three times per week for two additional weeks. The entire treatment consisted of 18 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and oswestry disability index (ODI) at pre-intervention, after two weeks treatment sessions, and at discharge (after 18 treatment sessions) were analyzed. Comparisons of changes in the disc herniation index (DHI) at pre-intervention and at discharge were analyzed using the paired t-test. There were significant improvements in the outcome measures of MS Ibs, SLR test, and ODI score after 2 weeks and 4 weeks sessions of CDM combined with therapeutic modalities as compared with the pre-intervention. However, no significant different pre-test and post-test DHI. CDM combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with L4-5 HNP.

Within physical therapy education, there has been increased attention to curricula and course that emphasize problem solving, clinical reasoning, and synthesis of information across traditional discipline-specific boundaries. This article describes the development implementation, and outcomes of a problem-based learning course in Physical therapy. The course was designed to help students to integrate the various elements of a physical therapy curriculum and to enhance their abilities to respond to an ever-changing health care environment. An evaluation of the course by the first 50 students who completed it revealed both strengths and weaknesses. Students responded that the course enhanced their professional behavior, including interpersonal communication skills, team work, and follow-through with professional responsibilities. The learning package was developed by the authors and implemented to a college students during three weeks of the first semester of 2001. Most studies which conducted PBL module development were short period or temporary PBL package application and evaluation rather than a whole semester's. While, this study carried on partial integrated PBL curriculum development and application with recomposing content of the two subjects to one subject Physical therapy which includes four PBL packages. This package was developed from a simple concept to complex and partial integrated PBL curriculum application systematically variable learning methods such as discussion, practice, lecture, video. There are 2 classes, each class has 25 students, in the college. Each class has 5 small groups consisting 5 students. Two tutors proceeded discussion charging each class also, they used multiple methods and materials like tutorials, self-directed learning, lecture, and video. The package is 5 grades and 5 hours per week and the rate of discussion, lecture is 4, 1 respectively. One of the most change is the increase of interaction between students and tutors. Whenever students need information and suggestion, they can visit tutors who provide reading materials and guide for the direction of self learning. Therefore, this study describes the PBL package development process and application during one semester recomposing contents of two subjects to Physical therapy concepts. Besides, it will contribute to active application of existing each subject to tutors who intend to convert as PBL methods. The study has significant meaning to show potentiality of partially integrated PBL application, using systematic PBL package development from two subjects contents. However, when students' need of yearning is over the extent of Introduction of Physical therapy and Rehabilitation medicine, tutors should set learning extent. So, there is limitation to attain completely integrated PBL education within one subject, therefore, it is high lighted to proceed development of integrated curriculum to maximize learning effects of PBL. It is exected that partial integrated PBL package development and application will distribute to prosper excellent physiotherapist in practice.

Fruit of Lycium chinense Miller was known to Korean as traditional medicine that has effective components for strengtherning function of human body, especially liver. To study characteristics of the wine and Yakju made by fruit Lycium chinense Miller, general components such as organic acid, methanol, ester, fusel oil and $SO_2$ were analyzed after storing them for 10 and 20 days at $20^{\circ}C\;and\;30^{\circ}C$, respectively. Organic acid contents of the wine were mainly lactic, malic, tartaric and acetic acid. Ester and fusel oil contents of the wine were $4.0{\sim}5.0\;mg%$ and $12{\sim}30\;mg%$, respectively, and the values were smaller than those of the Yakju. Methanol content of the wine was $25{\sim}27\;mg%$. Storage temperature in terms of the quality of the wine and Yakju was better in $20^{\circ}C\;than\;30^{\circ}C$. Treatment of the wine and Yakju either by adding 100 ppm of $SO_2$ or heating at $60^{\circ}C$ for 30 min was better in quality than control for storage.

Panax ginseng C.A. Meyer has been used as a traditional medicinal ingredient and the ginseng flower-buds also proved to have good medicinal properties. In this study, in order to enhance immune activities of ginseng flower-bud, the ginseng flower-bud extract was being fermented by Bacillus subtilis KCTC 1022 (BS), Lactobacillus plantarum KCTC3 and Saccharomyces cerevisiae strain CHY1011 (SC). Mice were orally administered daily for two weeks at two different concentrations (100 and 200 mg/kg B.W.). Treatment samples were water extracts of ginseng flower-buds (FD), water extracts of fermented ginseng flower-buds (FM) and controls for saline solution. Cytokine production (IL-6, TNF-${\alpha}$) either stimulated with LPS or not stimulated with LPS was detected by the ELISA assay when using the cytokine kit. Cytokine was statistically increased at supplemented groups with LPS in both the 100 and the 200 mg/kg B.W. and treatment with FM significantly decreased the LPS-induced TNF-${\alpha}$ and IL-6 production more than the treatment with FD. The results of this study may suggest that supplementation with FM increases the immune function by regulating cytokine production capacity for activated macrophages.

Acanthopanax senticosus is an herb that has been used as a traditional remedy and medicine source. Its anti-inflammatory and, anti-oxidative effects have been reported in previous studies. This study aimed to investigate the effect of Acanthopanax senticosus water extracts on mouse macrophage cell in vitro. Mouse splenocyte proliferation increased after application of Acanthopanax senticosus water extract supplement of 5, 10, 50, 100, 250, 500, $1,000{\mu}g/mL$ after 48 h pre-treatment with a mitogen (ConA or LPS). The production of cytokines secreted by LPS and non LPS stimulated macrophages was detected by ELISA assay using a cytokine kit. Cytokine production (IL-2, IFN-${\gamma}$, and TNF-${\alpha}$) increased after water extract supplementation. The result of this in vitro study, showed that splenocyte proliferation and cytokine production by activated peritoneal macrophages were increased after Acanthopanax senticosus water extract in the range of $500{\sim}1,000{\mu}L/mL$. Thus, it is suggested that supplementation with Acanthopanax senticosus water extracts may enhance immune function by regulating splenocyte proliferation and enhancing cytokine production by activated macrophage.

Background: Panax ginseng (i.e., ginseng) root is extensively used in traditional oriental medicine. It is a modern pharmaceutical reagent for preventing various human diseases such as cancer. Ginsenosidesd-the major active components of ginsengd-exhibit immunomodulatory effects. However, the mechanism and function underlying such effects are not fully elucidated, especially in human monocytes and dendritic cells (DCs). Methods: We investigated the immunomodulatory effect of ginsenosides from Panax ginseng root on $CD14^+$ monocytes purified from human adult peripheral blood mononuclear cells (PBMCs) and on their differentiation into DCs that affect $CD4^+$ T cell activity. Results: After treatment with ginsenoside fractions, monocyte levels of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and IL-10 increased through phosphorylation of extracellular signal-regulated kinase (ERK)1/2 and c-Jun N-terminal kinase (JNK), but not p38 mitogen-activated protein kinase (MAPK). After treatment with ginsenoside fractions, TNF-${\alpha}$ production and phosphorylation of ERK1/2 and JNK decreased in lipopolysaccharide (LPS)-sensitized monocytes.We confirmed that DCs derived from $CD14^+$ monocytes in the presence of ginsenoside fractions (Gin-DCs) contained decreased levels of the costimulatory molecules CD80 and CD86. The expression of these costimulatory molecules decreased in LPS-treated DCs exposed to ginsenoside fractions, compared to their expression in LPS-treated DCs in the absence of ginsenoside fractions. Furthermore, LPS-treated Gin-DCs could not induce proliferation and interferon gamma (IFN-${\gamma}$) production by $CD4^+$ T cells with the coculture of Gin-DCs with $CD4^+$ T cells. Conclusion: These results suggest that ginsenoside fractions from the ginseng root suppress cytokine production and maturation of LPS-treated DCs and downregulate $CD4^+$ T cells.

Portulaca oleracea L., a species of Portulacaceae, is ubiquitous. It is a well-known traditional Chinese medicine for removing heat, counteracting toxicity, cooling blood, and maintaining hemostasia; it is also used as antidysentery agent. This study investigated the anti-oxidative and anti-inflammatory activities of water and ethanol extracts from P. oleracea. The total polyphenol content ($21.08{\pm}0.03mg\;GAE/g$) and total flavonoid content ($5.45{\pm}0.76mg\;QE/g$) of the ethanolic extracts were higher than those of the water extracts. The antioxidative activities were determined by evaluating the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activity and by the ferric reducing antioxidant potential (FRAP) assay. The ABTS radical scavenging activity of the water extract (75.53%) was higher in those of the water extract (67.03%) at concentration of $1,000{\mu}g/mL$. The DPPH radical scavenging activity and FRAP of the ethanol extract were higher than those of the water extract. We also investigated the anti-inflammatory activity of the P. oleracea extracts in LPS-stimulated Raw 264.7 cells. The production levels of nitric oxide (NO) and reactive oxygen species (ROS) significantly decreased with an increasing concentration of the extract. The expression levels of pro-inflammatory cytokines (tumor necrosis faction (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-6) were significantly lower in the ethanol extract than in the LPS alone treatment group. Based on these results, ethanolic extract from P. oleracea could be an effective antioxidant and anti-inflammatory agent.

Frankincense has been used as a traditional medicine for treating rheumatoid arthritis, dermatitis, and muscle pain. In this study, the anti-tuberculosis effects of Frankincense were evaluated in immune responses of macrophages. Frankincense methanol extract was not cytotoxic to the host. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction assay using human macrophage (THP-1) cells did not show cytotoxic effects or morphological changes with treatments of 31.3, 62.5, and 125 ㎍/mL Frankincense methanol extract (FRM). Inhibitory effects of Frankincense methanol extract on the growth of Mycobacterium tuberculosis in human macrophages were investigated. The immune response was measured by monitoring the levels of TNF-α and IL-1β in THP-1 cells with or without M. tuberculosis infection under Frankincense methanol extract treatment. Inflammatory cytokine levels and M. tuberculosis numbers were reduced in THP-1 cells treated with Frankincense methanol extract. Therefore, Frankincense methanol extract could be used as a potential anti-tuberculosis agent.

Obesity is associated with impaired intestinal epithelial barrier function, which contribute to host systemic inflammation and metabolic dysfunction. Korean traditional foods, fiber-rich bean products, have been various biological activities in anti-inflammatory responses, but has not reported the large intestinal health. In this study, we investigated the intestinal health promoting effect of cooked soybeans (CSB) on high fat diet (HFD)-induced obesity model. SD rat were fed either a HFD or HFD supplemented with 10.6% CSB (HFD+CSB) for animal experimental period. CSB treatment significantly decreased the HFD-induced weights of body and fat. Also, CSB treatment improved HFD-reduced tight junction components (ZO-1, Claudin-1, and Occludin-1) mRNA expression in large intestine tissue. Additionally, histopathological evaluation showed that CSB treatment attenuated the HFD-increased inflammatory cells infiltration and epithelial damages in large intestine tissue. At the genus level, effects of CSB supplement not yet clear, while dietary effects showed differential abundance of several genera including Lactobacillus, Duncaniella, and Alloprevotella. NMDS analysis showed significant microbial shifts by HFD, while CSB did not shift gut microbiota. CSB increased the abundance of the genera Anaerotignum, Enterococcus, Clostridium sensu stricto, and Escherichia/Shigella by linear discriminant analysis effect size analysis, while reduced the abundance of Longicatena and Ligilactobacillus. These findings indicate that CSB supplement improves HFD-deteriorated large intestinal health by the amelioration of tight junction component, while CSB did not shift gut microbiotas.

Leonurus japonicus (L. japonicus) Houtt., a biennial plant in the Lamiaceae family is broadly distributed in Asia such as Korea, China, Japan. The aerial part of L. japonicus is used as a traditional medicine to treat uterine disease including dysmenorrhea, amenorrhea, sterility. In this study, we examined the antioxidant and anti-inflammatory effects of L. japonicus ethanol extracts. The antioxidant activity of L. japonicus was measured by total polyphenol and flavonoid content, and DPPH, ABTS scavenging, reducing power activity, and intracellular ROS expression assay. The anti-inflammatory effects were measured by nitric oxide (NO), cytokines (TNF-α and IL-1β) production and inflammatory protein expression in LPS-induced RAW 264.7 cells. Total polyphenol and flavonoid content of L. japonicus were 51.40 ± 0.47 mg of gallic acid equivalents/g and 73.28 ± 0.10 mg of rutin equivalents/g respectively. DPPH, ABTS radical scavenging activity and reducing power activity tended to increase concentration-dependent and treatment L. japonicus with 400 ㎍/mL reduced ROS production by 69.5%. Furthermore, L. japonicus inhibited NO, TNF-α and IL-1β production in a concentration-dependant manner and reduced the expression levels of inflammatory proteins via regulating NF-κB, MAPK pathway. Therefore, we suggest that L. japonicus could be a natural antioxidants and medicinal source to treat oxidative stress and inflammation-related disease.
