Digital extensor hypoplasia (DEH) is a rare malformation that presents with loss of active finger extension at the metacarpophalangeal (MCP) joints. Descriptions of optimal treatment and outcomes in this population are sparse. We describe successful operative treatment of a child with DEH involving the extensor digitorum communis, extensor digiti minimi, and the extensor indicis proprius tendons. The 5-year-old male patient was referred for severe limitation on bilateral finger extension since birth. He had been previously diagnosed with arthrogryposis and managed conservatively. Due to lack of improvement, magnetic resonance imaging was done evidencing hypoplasia/aplasia of the extensor tendons. The patient underwent successful tendon transfers using extensor carpi radialis longus to the common extensor tendons, and one hand required an additional tenolysis procedure. 2 years postoperatively, his MCP position and finger extension are markedly improved, and he is able to grip objects without limitation or difficulty. The patient returned to full activity without restriction.

Objectives : NK cells are spontaneously cytotoxic lymphocytes. These are not only important parts in the first line of defence against bacterial and viral infections of outside, but they may also play a critical role in chronic viral diseases. NK cells kill their targets spontaneously, without the need for prior sensitization and class I MHC restriction by the regulation of cytolytic functions and secretion of a variety of cytokines, such as interleukin-12(IL-12), MCP-1, IL-6, TNF-${\alpha}$, IFN-${\gamma}$. In addition, macrophage and NK cells cooperate through the production of cell mediates. These cooperation and modulation are one of major factors to prevent for evading immune surveillance of cancer. Hence, it could be assumed that if any candidate to enhance activities of macrophage and NK cell, it is considered as a potentially useful agents against cancer. Methods : In our study, to investigate effect of fermented soybean extracts by Lactic acid bacteria (SFE, soybean fermented extracts) work on intestinal immune cell to maintain general immune modulating and anti-cancer activity. We analyzed NK cytotoxicity assay and gene expressions of cytokine related with macrophage and NK cell activity. Results : In vitro experiment, SFE was verified as safety material for cell toxicicty to tumor cell strain without any toxicity of tumor growth inhibition and various cell strain. Effects of macrophage activity stimulating directly by SFE measured induced cytokine. The studies showed that IL-12 production by stimulation of SFE depended on concentration from 0.16mg/mL to 0.63mg/mL with non toxicity to cell, and it was the best activity at 0.63mg/mL. Besides, the effective concentration of SFE producing TNF-${\alpha}$ is similar to IL-12, but it was the best activity at 1.25mg/mL. The level of MCP-1, IL-6 and IFN-${\gamma}$ depended on concentration from 0.16mg/mL to 10mg/mL, IFN-${\gamma}$ showed the best activity at the effective concentration of 0.63mg/mL. With the result of NK cell activity measurement, the spleen cell of mouse injected SFE had 1.5 times higher killing effect than non injected cell. Conclusions : The result of this studies is that Soybean fermetated extracts(SFE) has possibility to immune aided material for the function not only inhibition of microbial infection to macrophage but also activity of adaption immune and cellular immune system.

Purpose : This study was performed to investigate the effects of Sobokchukeo- Tang(SCT) on the experimentally-induced endometriosis in rats. Materials and Methods : Endometriosis was induced via the surgical autotransplantation technique in rats. A laparotomy was performed and a $4\;{\times}\;4\;mm$ of the right uterine horn was resected incised and sutured to the peritoneum. And the animals divided into control(n=8) and SCT-treated group(n=8). SCT(1,000 mg/head) was administered orally for 15 days after operation. The weights(body, left uterus, and ovaries) and concentrations of cytokines(MCP-1,$TNF-{\alpha}$, $IL-l{\beta}$) were measured. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cells of the transplanted uterine tissues were performed. Results : - The $volume(mm^3)$ of transplanted uterine tissues of SCT-treated group$(92.88{\pm}41.89)$ was significantly(p<<0.01) decreased than the control group $(404.50{\pm}317.68)$. The concentration(pg/ml) of MCP-1 in ascites of SCT-treated group$(5,256{\pm}1,209)$ was significantly(p<<0.001) decreased than the control group$(8,632{\pm}1,245)$. - The concentration(pg/ml) of $TNF-{\alpha}$ in ascites of SCT-treated group$(521.8{\pm}306.1)$ was significantly(p<<0.01) decreased than the control group$(1,245.2{\pm}362.2)$. - The percentage of COX-2 positive epithelial layer in transplanted uterine tissues of SCT-treated group$(25.0{\pm}7.3)$ was significantly(p<<0.001) decreased than the control group$(50.2{\pm}8.2)$. - The number of mast cells in the stroma of transplanted uterine tissues of SCT-treated group$(16.5{\pm}6.8)$ was significantly(p<<0.05) decreased than the control group$(26.0{\pm}7.7)$. - The number of mast cells in the periphery of transplanted uterine tissues of control group$(71.3{\pm}18.5)$ was significantly(p<<0.01) decreased than the control group$(109.3{\pm}30.2)$. - Proliferation of epithelia, infiltration of inflammatory cells, and microanglogenesis in transplanted uterine tissues of treated group were weakly observed than the control group. Conclusion : From the above results, Sobokchukeo-Tang(SCT) has an inhibitory effect on the development of transplanted uterine tissue in rats and it is related to the decreased concentration of MCP-1 and $TNF-{\alpha}$, and decreased expression of COX-2, and decreased infiltration of mast cells by administration of Sobokchukeo-Tang.

Purpose: This study was performed to investigate the effects of Keukhachukeo-Tang (KCT) on the development of experimentally-induced endometriosis in rats. Methods : Endometriosis was induced in rats by autotransplanting uterine tissue to the peritoneum and devided them into three groups: (1) sham-operated group (n=8), (2) surgically induced endometriosis and untreated control group (n =8), (3) surgically induced endometriosis and KCT treated group. KCT (1,200 mg/head) was orally administrated for 15 days after operation. Then we measured the body weight, the volumes of endometriotic implants. The weight (body, left uterus and ovaries) and concentrations of cytokines (MCP-1, TNF-${\alpha}$, IL-l${\beta}$) in serum and peritoneal fluid were also measured. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cells in transplanted uterine tissue were performed. Results : - The volumes(mm$^3$) of endometriotic implants in KCT-treated group (107${\pm}$66) were significantly decreased (p<0.05) compared with control group (405${\pm}$318). - The contents(pg/ml) of MCP-1 in peritoneal fluid in KCT-treated group (6,940${\pm}$893) were significantly decreased (p<0.01) compared with control group (8,632${\pm}$1,245). - The contents(pg/ml) of TNF-${\alpha}$ in peritoneal fluid in KCT-treated group (847${\pm}$330) were significantly decreased (p<0.05) compared with control group (1,245${\pm}$362). - The percentages(%) of positive epithelial layers for COX-2 in KCT-treated group (31${\pm}$10) were significantly decreased (p<0.01) compared with control group (50${\pm}$8). - The numbers of mast cells in adjacent tissue of transplanted uterine tissue in KCT-treated group (69${\pm}$18) were significantly decreased (p<0.01) compared with control group (109${\pm}$30). - The numbers of mast cells in stroma of transplanted uterine tissue in KCT-treated group(16${\pm}$5) were significantly decreased (p<0.01) compared with control group (26${\pm}$8). - Histopathologically, proliferation of endometriotic epithelia and stroma, and infiltration of inflammatory cells in transplanted uterine tissue of KCT-treated group were weakly observed than those of control group. Conclusion : From the above results, Keukhachukeo-Tang (KCT) have inhibiting effects on the development of transplanted uterine tissue. And these effects are related to the decreased concentration of MCP-1 and TNF-${\alpha}$, decreased expression of COX-2, and decreased infiltration of mast cells by administration of Keukhachukeo-Tang.

Amomum cadamomum Linne (ACL) has long been utilized against the inhibited qi movement related diseases such as dyspepsia, acute gastroenteritis, vomiting and diarrhea in Korean medicine. We speculated that ACL could improve the metabolic disorders such as obesity and type 2 diabetes through removing the phlegm-dampness and promoting the qi movement or stagnation. This study was designed to investigate effects and molecular mechanisms of ACL extract on the improvement of adipocyte dysfunction induced by TNF-α in 3T3-L1 adipocytes. Potential roles of ACL extract in the lipogenesis, inhibition of inflammatory cytokines and insulin resistance, were investigated in this study. Also, we examined the adipose genes and signaling molecules related to insulin resistance and glucose uptake to elucidate its mechanism. Our data demonstrated that TNF-α significantly incresed the release of lipid droplets and the production of MCP-1 and IL-6 from adipocytes. In gene expression, TNF-α reduced the expression of aP2, PPARγ, C/EBPα, GLUT4, and IRS-1 related to lipogenesis and insulin sesitivity, while TNF-α increased the expression of MCP-1 related to inflammation. In addition, TNF-α down-regulated the PPARγ and IRS-1 protein and up-regulated the IRS-1 Ser307 phosphorylation. These alterations induced by TNF-α were prevented by the treatment of ACL extract. Thus, our results indicate that ACL extract can be used to prevent from the TNF-α-induced adipocyte dysfunction through insulin and PPARγ pathways.

Objectives : This study aims at examining the immuno-modulating activity in the fermentative extract of the root of Scutellaria baicalensis Georgi (Scutellariae Radix) on the production of inflammatory mediator in LPS-stimulated RAW264.7 mouse macrophages. Method : Measurements were done for the influences on the cell viability, generation of hydrogen peroxide in cells and nitric oxide (NO) generation using the macrophage of mouse with the specimen SBS as the fermentative extract of Scutellariae Radix (SBS) with Saccharomyces cerevisiae STV89. Result : As a result of carrying out MTT assay to check the cellular toxicity of the fermentative extract of Scutellariae Radix, any excessive toxicity to the macrophage did not occur from treatments by concentration for SBS. SBS increased the generation of hydrogen peroxide in the macrophage. SBS suppressed the NO generated in macrophages and SBS concentration higher than $25{\mu}g/mL$ significantly suppressed the increased NO generated in LPS-stimulated macrophages. SBS concentration higher than $25{\mu}g/mL$ significantly suppressed the generation of IL-6, IL-10, IL-12p40 and MCP-1 in LPS-stimulated macrophages. Conclusion : Our findings indicate that SBS has an immuno-modulating activity in macrophage activation through suppressing the generation of inflammatory substances, NO, IL-6, IL-10, IL-12p40 and MCP-1.

Compound K (20-O-β-(_D-glucopyranosyl)-20(S)-protopanaxadiol) is an active ingredient of ginsenosides. Compound K has been known to produce from biotransformation by β-glucosidase action of human intestinal microbes after oral admistration of ginseng. We have investigated the cytotoxicity of compound K obtained from bio-converted ginseng extract. As a result, compound K showed no significant cytotoxicity in the concentration of 0.001 to 1 ㎍/mL and inhibited the production of TNF-α, MCP-1, IL-6 and NO in RAW 264.7 cells induced by LPS inflamation. In the same concentration, HaCaT cells induced by inflammation with TNF-α and IFN-γ decreased IL-8 production due to compound K treatment. In the brine shrimp lethality assay, the LC₅₀ of compound K was 0.37 mg/mL indicating some toxicity, but the bioconverted product containing 35% compound K showed relatively low toxicity with an LC₅₀ of 0.87 mg/mL. These results suggest that the compound K enriched extract is a potential functional material for acne relief cosmetic products.

Germinated brown rice (GBR, Orysa sartiva L.) has been reported to have anti-obesity and anti-inflammatory effects. However, the mechanisms underlying these effects in adipocytes are not fully understood. Therefore, this study was conducted to explore the anti-inflammatory mechanisms of GBR on lipopolysaccharide (LPS)-stimulated 3T3-L1 adipocytes. 3T3-L1 adipocytes were pretreated with GBR extracts (0-20 mg/mL) 1 h before LPS stimulation. The mRNA expression of adipokines and Toll-like receptor 4 (TLR4) were measured by RT-PCR. The protein expressions of TLR4-related molecules were detected by western blotting and nuclear factor-${\kappa}B$ ($NF-{\kappa}B$) activation was measured. Our results showed that GBR extract dose-dependently inhibited mRNA expression of LPS-induced tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1). GBR extract was found to inhibit LPS-induced mRNA expression of TLR4 and protein expression of both myeloid differentiation factor 88 (MyD88) and TNF receptor-associated factor 6 (TRAF6). Furthermore, GBR extract significantly inhibited extracellular receptor-activated kinase (ERK) phosphorylation and $NF-{\kappa}B$ activation. These results suggest that GBR extract has the anti-inflammatory effects on LPS-induced inflammation via inhibition of TLR4 signaling, includingthe ERK and $NF-{\kappa}B$ signaling pathways, in adipocytes.

In vitro studies using detached inflorescences with peduncles were conducted to investigate flower abscission agents in North American ginseng (Panax quinquefolius L.). Of the nine compounds studied only three, ammonium thiosulphate (ATS), abscisic acid (ABA) and ethephon induced abscission. Anilazine, benzyladenine, carbaryl, gibberellic acid, napthaleneacetic acid and thidiazuron did not induce abscission. ATS dip treatments did not induce abscission but the spray treatments induced $60.5\%$ abscission at $1500\;mg{\cdot}L^{-1}$ and $33.1\%$ at $3000\;mg{\cdot}L^{-1}$. Severe chlorophyll loss occurred on all inflorescences treated with ATS. Both ABA dip treatments and a $250\;{\mu}mol{\cdot}L^{-1}$ spray treatment caused abscission $(40\%)$ without adverse effects, and timing of ABA application was important. Because ABA was only significant in the dip treatments, ABA may not be a practical option for field use on ginseng. Ethephon sprays induced more abscission as the season progressed and as the concentration increased. As the dip concentrations of ethephon increased, the abscission rate decreased and the health of the inflorescences declined. The $1500\;mg{\cdot}L^{-1}$ spray of ethephon gave consistent abscission results over the glowing season with little phytotoxicity. Treatment with the competitive ethylene inhibitor 1-methylcy-clopropene (1-MCP) suggested that flower abscission was due to the liberation of ethylene from the breakdown of ethephon.

Atopic dermatitis is a recurrent or chronic eczematous skin disease with severe pruritus and has annually increased in Korea. In this study, we investigated whether Duchesnea chrysantha (Dc) extracts have an anti-inflammatory effect in human monocytic THP-1 cells and human eosinophilic EoL-1 cells. The dried and powdered whole plants of Dc were extracted with 80% EtOH (Dc-1). The residue was diluted with water, and then successively partitioned with n-hexane, EtOAc, and BuOH to produce the n-hexane (Dc-2), EtOAc (Dc-3), BuOH (Dc-4), and the water-soluble fractions (Dc-5), respectively. The mite extract and LPS increased the production of IL-6, IL-8 and MCP-1 in THP-1 cells and the increase was strongly suppressed by Dc-3 extract, as compare with other extracts. Dc-3 also inhibited the release of IL-6 increased by mite extract and LPS in EoL-1 cells. However, Dc-3 extract increased IL-8 production induced by the mite extract and LPS in EoL-1 cells. These results suggest that Dc extract may be used as anti-inflammatory agents in treating allergic disorders such as asthma and atopic dermatitis.
