To develop new therapeutic materials to prevent hair loss and enhance hair growth, we developed a medicinal herbal complex extract (MHCE) using 23 herbs traditionally used in oriental medicine. Medicinal Herbal complex extract was consist of Angelica gigas Nakai, Psoralea corylifolia Linne, Biota orientalis Endlicher, and Eclipta prostrata Linne, Rehmannia glutinosa Liboschitz var. purpurea Makino, Ligustrum lucidum Aiton, Polygonum multiflorum Thunberg, and Sesamum indicum Linne, Sophora angustifolia Sieboldet Zuccarini, Angelica dahurica Benthamet Hooker, and Leonurus sibiricus Linne, Salvia miltiorrhiza Bunge, Prunus persica Batsch, Commiphora molmol Engler, Chrysanthemum indicum Linne, Boswellia carterii Birdwood, Panax ginseng C. A. Meyer, Cnidium officinale Makino, Albizia julibrissin Durazzini, and Corydalis ternata Nakai that have traditionally been used for treating hair loss, preventing gray hair, anti-inflammation, and blood circulation in oriental medicine. In addition, we examined the hair growth effect of MHCE in vitro and in vivo. In vitro, we evaluated the effects of MHCE on cultured HFDPC, HaCaT cells, and murine embryonal fibroblasts (NIH3T3 cells). Also, we evaluated the ability of MHCE to prevent gray hair on murine melanoma cells (B16F1 cells). The hair growth-promoting effect of MHCE in vitro was also observed in vivo using C57BL/6 mice. Our results showed that MHCE significantly increased the proliferation of HFDPC (175 % proliferation at $50{\mu}g/mL$), HaCaT cells (133 % proliferation at $20{\mu}g/mL$), and NIH3T3 cells (120 % proliferation at $50{\mu}g/mL$). MHCE also showed consistent melanogenesis in B16F1 cells (154 % melanin synthesis at $50{\mu}g/mL$). Moreover, MHCE showed potential for hair growth stimulation in C57BL/6 mice experiments (98 % hair growth area on 4 weeks). These results indicate that MHCE may be a good candidate for promotion of hair growth.

Background: Folylpolyglutamate synthetase (FPGS), an important enzyme in the folate metabolic pathway, plays a central role in intracellular accumulation of folate and antifolate in several mammalian cell types. Loss of FPGS activity results in decreased cellular levels of antifolates and consequently to polyglutamatable antifolates in acute lymphoblastic leukemia (ALL). Materials and Methods: During May 1997 and December 2003, 134 children diagnosed with ALL were recruited from one hospital in Thailand. We performed a mutation analysis in the coding regions of the FPGS gene and the association between single nucleotide polymorphisms (SNPs) within FPGS in a case-control sample of childhood ALL patients. Mutation screening was conducted by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and subsequently with direct sequencing (n=72). Association analysis between common FPGS variants and ALL risk was done in 98 childhood ALL cases and 95 healthy volunteers recruited as controls. Results: Seven SNPs in the FPGS coding region were identified by mutation analysis, 3 of which (IVS13+55C>T, g.1297T>G, and g.1508C>T) were recognized as novel SNPs. Association analysis revealed 3 of 6 SNPs to confer significant increase in ALL risk these being rs7039798 (p=0.014, OR=2.14), rs1544105 (p=0.010, OR= 2.24), and rs10106 (p=0.026, OR=1.99). Conclusions: These findings suggested that common genetic polymorphisms in the FPGS coding region including rs7039789, rs1544105, and rs10106 are significantly associated with increased ALL risk in Thai children.

Two possible space groups of the comfound, VP6N3018C24H:60, are: P 1, a=14.022(1), b=12.644(2), c= 12.640(1)A, a=8038(1), B=102.12(1), r=102.16(1), V=2124.1A3, Z=2, μ=0.47cm-1, d=1.46g/cm3, R=0.083 for 3350 independent reflections with Fo>4o IFI, and C2/c, a=19.32(2), b=16.32(2), c=14.02(1)A, B=105.98(5), β=105.98(5), V=4248.2A3, Z=4 R=0.083 for 1590 independent reflections with Fo>4c IFoI . In the space group P T, there are two monlecules in a unit cell. Vanadium atoms in the two monlecules occupy the two different special positions such that the complete monlecules are accomplished by the two independent center of symmetry. Therefore two different half molecules of bis(trimetaphosphate)vanadate and three molecules of tetraethylammonium are the asymmetric unit in a unit cell. In the space group C2/c, however, the vanadium atom is located at a special position with centrosymmetry, and a two-fold symmetry axis passes through C2/c, N2 and C25 atoms. Therefore the asymmrtic unit in a unit cell consists of a half molecule of bis(trimetaphosphate)vanadate and one and a half molecules of tetraethylammonium. All the molecular conformations in both space groups are very similar: six oxygen atoms coordinated to a vanadium atom in the bi s(trimetaphosphate)vanadate molecule form an octahedron and the four carbon atoms bonded to a nitrogen atom in the tetraethylammonium molecule are disordered so that the eight carbon atoms around nitrogen atom exhibit an irregular dodecahedral form.

Background: The present study examines a hypothesis that short allergen-derived peptides may shift an Aspergillus fumigatus (Afu-) specific TH2 response towards a protective TH1. Five overlapping peptides (P1-P5) derived from Asp f1, a major allergen/antigen of Afu, were evaluated for prophylactic or therapeutic efficacy in BALB/c mice. Methods: To evaluate the prophylactic efficacy, peptides were intranasally administered to naive mice and challenged with Afu-allergens/antigens. For evaluation of therapeutic efficacy, the mice were sensitized with Afu-allergens/antigens followed by intranasal administration of peptides. The groups were compared for the levels of Afu-specific antibodies in sera and splenic cytokines evaluated by ELISA. Eosinophil peroxidase activity was examined in the lung cell suspensions and lung inflammation was assessed by histopathogy. Results: Peptides P1-, P2- and P3 decreased Afu-specific IgE (84.5~98.9%) and IgG antibodies (45.7~71.6%) in comparison with Afu-sensitized mice prophylactically. P1- and P2-treated ABPA mice showed decline in Afu-specific IgE (76.4~88%) and IgG antibodies (15~54%). Increased IgG2a/IgG1 and IFN-${\gamma}$/IL-4 ratios were observed. P1-P3 prophylactically and P1 therapeutically decreased IL-5 levels and eosinophil peroxidase activity. P1 decreased inflammatory cells' infiltration in lung tissue comparable to non-challenged control. Conclusion: Asp f1-derived peptide P1, prophylactically and therapeutically administered to Balb/c mice, is effective in regulating allergic response to allergens/antigens of Afu, and may be explored for immunotherapy of allergic aspergillosis in humans.

Cynanchi wilfordii Radix (CW) and Perilla sikokiana (PS) were extracted under different conditions to study their antioxidant, anti-diabetic, and anti-obesity activities. Their potentials as functional food ingredients were investigated. The highest total phenol contents were $15.74{\pm}0.69mg/g$ for CW100 [100% fermented ethanol (FE) extract from CW] and $39.37{\pm}3.46mg/g$ for PS50 (50% FE extract from PS). When extracts were processed at 1 mg/mL, DPPH radical scavenging activities were $79.79{\pm}0.79%$ and $82.69{\pm}1.07%$, respectively, at CW100 and PS50. ABTS radical scavenging activities were $80.20{\pm}2.86%$ and $75.00{\pm}1.78%$, respectively, at CW100 and PS50. However, ferric reducing antioxidant power activities at 1 mg/mL were higher than 80% for PS under all extraction conditions. The highest ${\alpha}$-amylase inhibitory activities were $51.56{\pm}0.56{\sim}59.2{\pm}1.13%$ at CW50 and $46.70{\pm}0.32{\sim}66.17{\pm}0.55%$ at PS0. Cell differentiation inhibitory effects in 3T3-L1 adipocytes were $29.49{\pm}2.98%$ at CW100 and $23.31{\pm}0.61%$ at PS50. The inhibitory effect of the CW100-PS50 mixture was $43.03{\pm}1.63%$, which was significantly higher than those of individual extracts.

Protein arginine methyltransferase 1 (PRMT1), a type-I arginine methyltransferase, has been implicated in diverse cellular events. We have focused on the role of PRMT1 in gliomagenesis. In this study, we showed that PRMT1 expression was up-regulated in glioma tissues and cell lines compared with normal brain tissues. The knock-down of PRMT1 resulted in an arrest in the G1-S phase of the cell cycle, proliferation inhibition and apoptosis induction in four glioma cell lines (T98G, U87MG, U251, and A172). Moreover, an in vivo study confirmed that the tumor growth in nude mouse xenografts was significantly decreased in the RNAi-PRMT1 group. Additionally, we found that the level of the asymmetric dimethylated modification of H4R3, a substrate of PRMT1, was higher in glioma cells than in normal brain tissues and decreased after PRMT1 knock-down. Our data suggest a potential role for PRMT1 as a novel biomarker of and therapeutic target in gliomas.

Side population (SP) cells have stem cell-like properties with a capacity for self-renewal and are resistant to chemotherapy and radiotherapy. Therefore the presence of SP cells in human breast cancer probably has prognostic value. Objective: To investigate the characteristics of SP cells and identify the relationship between the SP cells levels and clinico-pathological parameters of the breast tumor and disease-free survival (DFS) in breast cancer patients. Materials and Methods: A total of 122 eligible breast cancer patients were consecutively recruited from January 1, 2006 to December 31, 2007 at Yunnan Tumor Hospital. All eligible subjects received conventional treatment and were followed up for seven years. Predictors of recurrence and/or metastasis and DFS were analyzed using Cox regression analysis. Human breast cancer cells were also obtained from fresh human breast cancer tissue and cultured by the nucleic acid dye Hoechst33342 with Verapami. Flow cytometry (FCM) was employed to isolate the cells of SP and non-SP types. Results: In this study, SP cells were identified using flow cytometric analysis with Hoechst 33342 dye efflux. Adjusted for age, tumor size, lymph nodal status, histological grade, the Cox model showed a higher risk of recurrence and/or metastasis positively associated with the SP cell level (1.75, 1.02-2.98), as well as with axillary lymph node metastasis (2.99, 1.76-5.09), pathology invasiveness type (1.7, 1.14-2.55), and tumor volume doubling time (TVDT) (1.54, 1.01-2.36). Conclusions: The SP cell level is independently associated with tumor progression and clinical outcome after controlling for other pathological factors. The axillary lymph node status, TVDT and the status of non-invasive or invasive tumor independently predict the prognosis of breast cancer.

This study was conducted to evaluate the effects of rumen protected choline on in vitro ruminal fermentation and milk production and its composition in Holstein cows. Experiments were done with three treatment groups, basal diet without any supplement (T1), basal diet+23g/d of mixture of choline and wheat shorts (T2) and basal diet + 25.56 g/d of rumen protected choline (T3). The in vitro ruminal pH and ammonia concentrations were similar for three treatments during all incubation periods except for the in vitro ruminal pH on 3 hr incubation and ammonia concentrations on 9 hr incubation. No significant difference was found in the concentrations of acetate and total-VFA. The propionate and butyrate concentrations were not affected by the rumen protected choline except on 6 hr incubation on which the propionate and butyrate concentrations were intermediate (8.98 mg/dl) and least (3.22 mg/dl), respectively. Higher milk yield and milk fat and lactose were resulted in the rumen protected choline. However, the rumen protected choline did not affect the milk protein, solids not fat, total solids, MUN, somatic cell count. It is concluded that the rumen protected choline can be effective materials to improve the milk production, milk fat and lactose without little change on in vitro ruminal fermentation.

We studied the antioxidant, the anti-inflammatory, antithrombotic, and antiobesity activities of seven different kinds of edible plants. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS radical scavenging activities were determined as a measurement of antioxidant activity. NO production inhibition by the macrophage cell line (Raw 264.7) treated with lipopolysaccharide (LPS) was carried out to assess anti-inflammatory activity. Thrombin inhibitory activity was measured for its antithrombotic function and inhibition of 3T3-L1 cell differentiation was evaluated as a measurement of antiobesity activity. Total phenolic components and total flavonoid contents were measured to determine functional materials in medicinal plants. Common sage, Japanese lady bell, and hairy agrimony showed high antioxidant activity ($IC_{50}$) of less than $100{\mu}g/mL$. All samples used in this study showed anti-inflammatory activity. Common sage, hairy agrimony, and hooker chives showed antithrombotic effects. Hairy agrimony showed the highest antithrombotic effect (98.1%). Common sage, Japanese lady belly, hairy agrimony, and hooker chives showed reduced 3T3-L1 cell differentiation and hooker chives strongly inhibited lipid accumulation in the cells compared to other medicinal plants. Common sage and hairy agrimony contained more than 1 mg GAE/g of phenolic compounds and more than 1 mg CE/g of flavonoids. Functional activities were different by plant part and extraction method from each sample. These results suggest that common sage, Japanese lady belly, hairy agrimony, and hooker chives may be used as healthy food sources with antioxidant, anti-inflammatory, antithrombotic, and antiobesity activities, and appropriate extracting methods from each plant need to be developed.

Background: Recent studies have suggested that UFT may be an effective adjuvant therapy for completely resected IB (pT2N0) non-small cell lung cancer (NSCLC). We designed this study to clarify the feasibility of performing adjuvant chemotherapy with UFT for completely resected IB nor-small cell lung cancer, Material and Method: We randomly assigned patients suffering with completely resected IB non-small cell lung cancer to receive either UFT 3g for 2 year or they received no treatment. All patients had to be followed until death or the cut-off date (December 31 2006). Result: From June 2002 through December 2004, 64 patients were enrolled. Thirty five patients were assigned to receive UFT (the UFT group) and 29 patients were assigned to observation (the control group). A follow-up surrey on the 3 year survival rate was successfully completed for all the patients. The median follow-up time for all the patients was 32.8 months. In the UFT group, the median time of administration was 98 weeks (range: $2{\sim}129$ weeks). The rate of compliance was 88.2% at 6 months, 87.5% at 12 months, 80.6% at 18 month and 66.7% at 24 months. Seven recurrences (24.1%) occurred in the control group and six (17.1%) occurred in the UFT group (p=0,489). The three-year disease free survival rate was 71.3% for the control group and 82.0% for the UFT group (p=0.331). On the subgroup analysis, the three-year disease free survival rate for the patients with adenocacinoma was 45.0% for the control group and 75.2% for the UFT group (p=0.121). The three-year disease free survival rate for the patients with non-adenocarcinoma was 88.1% for the control group and 88.9% for the UFT group (p=0.964), Conclusion: Postoperative oral administration of UFT was well-tolerated. Adjuvant chemotherapy with UFT for completely resected pT2N0 adenocarcinoma of the lung could be expected to improve the disease free survival, but this failed to achieve statistical significance. A prospective randomized study for a large number of patients will be necessary.
