  • Objectives: Cornu cervi pantotrichum (CCP) has been widely used in Korean and China, as an anti-fatigue, anti-aging, and tonic agent to enhance the functions of the reproductive and the immune systems. Because CCP has various growth factors that play important roles in the development of hair follicles, we examined whether CCP pharmacopuncture solution (CCPPS) was capable of promoting hair growth in an animal model. Methods: One day after hair depilation, CCPPS were topically applied to the dorsal skin of C57BL/6 mice once a day for 15 days. Hair growth activity was evaluated by using macro- and microscopic observations. Dorsal skin tissues were stained with hematoxylin and eosin. Expressions of bromodeoxyuridine (BrdU), proliferating cell nuclear antigen (PCNA), and fibroblast growth factor (FGF)-7 were examined by using immunohistochemical staining. A reverse transcription polymerase chain reaction (RT-PCR) analysis was also conducted to measure the messenger RNA (mRNA) expression of FGF-7. Results: CCPPS induced more active hair growth than normal saline. Histologic analysis showed enlargement of the dermal papilla, elongation of the hair shaft, and expansion of hair thickness in CCPPS treated mice, indicating that CCPPS effectively induced the development of anagen. CCPPS treatment markedly increased the expressions of BrdU and PCNA in the hair follicles of C57BL/6 mice. In addition, CCPPS up regulated the expression of FGF-7, which plays an important role in the development of hair follicles. Conclusion: These results reveal that CCPPS facilitates hair re-growth by proliferation of hair follicular cells and up-regulation of FGF-7 and suggest that CCPPS can potentially be applied as an alternative treatment for patients with alopecia.

  • Objectives: Recently, thread-embedding therapy (TET) has been widely applied in Korean medicine for cosmetic purposes such as reducing skin wrinkles. An inserted thread was reported to have induced continuous stimulation, followed by support for connective tissue regeneration. However, the potential role of TET in hair-growth has not yet been reported. Methods: We designed this study to evaluate whether TET has a hair-growth-promoting effect. C57 black 6 (C57BL/6) mice were divided into three groups: normal saline-treated, minoxidil-treated, and thread-embedded groups. Normal saline or 5% minoxidil was topically sprayed on the dorsal skin of the mice once a day for 16 days. Medical threads were embedded into the dorsal skin of the mice in a single application. Hair growth activity was evaluated by using dermoscopic and microscopic observations. Sections of the dorsal skin were stained with hematoxylin and eosin. Expressions of bromodeoxyuridine (BrdU), proliferating cell nuclear antigen (PCNA), fibroblast growth factor-7 (FGF-7), and fibroblast growth factor-5 (FGF-5) were detected by using immunohistochemical staining. A reverse transcription-polymerase chain reaction (RT-PCR) analysis was adopted to measure the messenger RNA (mRNA) expressions of FGF-7 and FGF-5. Results: TET enhanced anagen development in the hair follicles of C57BL/6 mice. The expressions of BrdU and PCNA, both of which imply active cellular proliferation, were increased by using TET. Moreover, TET increased the expression of FGF-7, an anagen-inducing growth factor, while decreasing the expression of FGF-5, an anagen-cessation growth factor, both at the protein and the mRNA levels. Conclusion: TET enhanced hair re-growth in C57BL/6 mice. TET regulated the expressions of anagen-associated growth factors and activated the proliferation of hair follicular cells in depilated skin lesions. Considering its long-lasting effect, TET may be a good alternative therapeutic for the treatment of alopecia.

  • To investigate anti-cancer effects of wild ginseng herbal acupuncture and mitigation of anti-cancer drug when taken concurrently, cancer cells from B16/F10 melanoma were injected intraperitoneally in C57BL/6. After inducing cancer, anti-cancer effects and mitigation of reproductive toxicity of Doxorubicin were evaluated. 1. For changes in weight, Doxorubicin treated group showed significant decrease, and administration of wild ginseng herbal acupuncture didn't cause any weight change. 2. Volume of tumor was significantly reduced in Doxorubicin teated group. Wild ginseng herbal acupuncture groups showed slight decrease but insignificant compared to the control group. 3. For hematological evaluation, Doxorubicin only group's reticulocytes were significantly decreased compared to the control group, and Platelet Count was significantly increased. Wild ginseng herbal acupuncture group showed significant increase of Neutrophils and significant decrease of Lymphocytes compared to the control group. 4. For histological evaluation of the tumor, necrosis occurred in a wide range in the Doxorubicin treated group. Wild ginseng herbal acupuncture didn't cause much histological changes. 5. For histological evaluation of the testis, seminiferous tubules of the control group suffered severe damage on epithelial cells. When wild ginseng herbal acupuncture was administered concurrently, damage on the seminiferous tubules was significantly inhibited compared to the Doxorubicin only group. 6. Diameter of seminiferous tubules and spermatogonia count were insignificant between the experiment groups. 7. For BrdU positive reaction of testicle tissue, Doxorubicin only group failed to show any reaction of spermatogonia, but spermatocytes and spermatids showed slight positive reaction. When wild ginseng herbal acupuncture was treated concurrently, much greater positive reaction was made but similar to that of the control and normal groups. 8. For observation of changes in BrdU spermatogonia count of the testicle tissue, Doxorubicin only group didn't show any positive reaction, and relative increase was shown in the group with concurrent administration of wild ginseng herbal acupuncture. 9. For observation of TUNEL positive reaction cells of the testicle tissue, no significant changes were witnessed in all the experiment groups.

  • Ginseng is the best known and most popular herbal medicine used worldwide. In spite of reported beneficial effects of ginseng on the CNS, there is few scientific evidences established at the cellular level. Among more than 30 ginsenosides, Rb1 and Rg1, the active ingredients of ginseng, are regarded as the main compounds responsible for many pharmaceutical actions of ginseng. Daily treatment with Rb1 or Rg1 for 3 d significantly decreased the number of bromodeoxyuridine(BrdU)(+) cells in primary neural progenitor cells(NPCs) isolated from hippocampi at embryonic day 16.5(E16.5). In contrast, treatment with Rb1 or Rg1 greatly increased the number of microtubule associated protein(MAP2) (+) cells. In addition, the transcription factors, Ngn1 and Hes1, proneural members of the basic helix-loop-helix(bHLH) family, significantly increased in Rb1 or Rg1 treated-NPCs. Based on these results, we suggest for the first time that ginsenosides Rb1 and Rg1 decrease proliferation but promote neuronal differentiation of hippocampal NPCs.

  • Diesel Beitrag befasst sich mil der Sprache in gesellschaftlichen Umbruchssituationen aus der Perspektive einer spezifisch linguistischen Fragestellung. Im Zentrum der Untersuchung steht der Wandel der Sprachverwendung unter den Bedingungen der Demokratisierung der DDR und der Vereinigung mil der BRD seit der Wende 1989/90. Dieser Wandel wird am Beispiel der Lexik, und anhand von Losungen bzw. Demo-Spruchen konkretisiert. Im Zuge der 'Wende' sind $f\"{u}r$ beide Kommunikationsgemeinschaften - $\"{u}berwiegend$ aber $f\"{u}r$ die der neuen $Bundesl\"{a}nder$ - Neologismen in Gebrauch gekommen. Am bekanntesten sind: 'Mauerspecht', 'Wendehals', 'Moniagsdemo' und 'Stasi-Akte' usw. Andererseits wurden im Verlauf der Wende zahireiche Bezeichnungen, insbesondere $f\"{u}r$ $aufgel\"{o}ste$ Institutionen der DDR sowie viele verwaltungsspezifische $W\"{o}lfer$, historisiert. An Textbeispielen der Losungen des Herbstes 1989 werden uns die Dynamik sprachlicher Strukturen auf der einen Seite und die sich verandernden gesellschaftlichen $Verh\"{a}ltnisse$ in der $\"{o}ffentlichen$ Kommunikation der ehemaligen DDR auf der anderen Seite vol Augen gefuhrt. Verglichen mit den zum 1. Mai bekannt gegebenen of nziellen SED-Losungen, sind die Aktanten der Demo-Spruche das Volk, teils als Individuen und teils als spontan gebildete Gruppen. Im Unterschied zu den 'allen' offiziellen Losungen $repr\"{a}sentieren$ die Demo-$Spr\"{u}che$ verschiedenartige Sprechhandlungstypen: Nicht nur AUFFORDERN, APPELLIEREN, BEHAUPTEN, sondern auch FRAGEN, BESCHIMPFEN, DROHEN, $GR\"{U}{\ss}EN$usw. Gleichzeitig $\"{u}bernehmen$ sie viele Textmuster als sprachliche Stilmittel aus fem Bereich anderer Spruch- und Kurztextgattungen, wie zum Beispiel Sprichwort, Kinderreim, Aphorismus, Anspielung und verwenden auch Zitate. Auf diese Weise linden sich in den Wende-Losungen zahlreiche Belege $f\"{u}r$ intertextuelle $Bez\"{u}ge$. So schaffen diese Losungen $schlie{\ss}lich$ eine neue Qualitat des $\"{o}ffentlich-politischen$ Diskurses in der Gesellschaft. Am Rande der Untersuchungen haben wir $f\"{u}r$ das Deutsch in Ost und West festgestellt: $Bem\"{u}hungen$ der $Ann\"{a}herung$ und des sprachlich-kornrnunikativen Ausgleichs findet man seit der Wende 1989/90 eher auf der Seite der Ostdeutschen. Die sprachlichen Differenzierungen zwischen Ost- und Westdeutschland waren vornehmlich lexikalischer An. Es ist aber anzunehmen, dass es heute weniger die Sprache selbst ist als vielmehr das unterschiedliche Kommunikationsverhalten zwischen Ost- und Westdeutschen, das die Verstandigung zwischen Ost- und Westdeutschen schwierig zu machen scheint.

  • A chromosome territory is composed of chromosomal subdomains. The internal structure of chromosomal subdomains provides a structural framework for many genomic activities such as replication and DNA repair, and thus is key to determining the basis of their mechanisms. However, the internal structure and regulating proteins of a chromosomal subdomain remains elusive. Previously, we showed that the chromosome territory expanded after BAF53 knockdown. Because the integrity of chromosomal subdomains is a deciding factor of the volume of a chromosome territory, we examined here the effect of BAF53 knockdown on chromosomal subdomains. We found that BAF53 knockdown led to the disintegration of histone H2B-GFP-visualized chromosomal subdomains and BrdU-labeled replication foci. In addition, the size of DNA loops measured by the maximum fluorescent halo technique increased and became irregular after BAF53 knockdown, indicating DNA loops were released from the residual nuclear structure. These data can be accounted for by the model that BAF53 is prerequisite for maintaining the structural integrity of chromosomal subdomains.

  • Objectives : This study was performed to investigate the anti-fibrogenic effect of greater celandine on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells (HSC-T6) were treated with various concentrations of greater celandine extract for 24, 48, and 72 hours. The extraction was done with distilled water. After the treatment, cell viability, proliferation, mRNA of the ${\alpha}SMA$, TIMP-1, TIMP-2, collagen I ${\alpha}$ 1, MMP-2, IL-6, TGF-${\beta}1$, PDGFr-${\beta}1$, Bcl-2, Bax, Bcl-xl, caspase-3, caspase-9 and the activities of SOD and catalase were measured by using MTT assay, BrdU assay, real-time PCR, superoxide dismutase assay and catalase assay. Results : The viability, proliferation, mRNA expression and synthesis of collagen of the hepatic stellate cells were inhibited as the concentration increased, which indicates the herb has an inhibitory effect on fibrogenesis of the liver by regulating the fibrosis associated genes in transcription. Conclusions : These results suggest that greater celandine would be beneficial in the treatment of fibrotic patients as well as for patients with chronic hepatitis.

  • Background: S100A14 has recently been implicated in the progress of several types of cancers. This study aimed to investigate the clinical significance and possible mechanisms of action of S100A14 in the invasion and metastasis of hepatocellular carcinoma (HCC). Methods: S100A14 expression in HCC was detected at mRNA and protein levels and its prognostic significance was assessed. Functional roles of S100A14 in HCC were investigated using MTT, BrdU, wound healing, transwell invasion assay and HCC metastatic mouse model. Results: S100A14 was significantly elevated in HCC tissues, correlated with multiple tumor nodes, high Edmondson-Steiner grade and vascular invasion. Multivariate Cox analysis showed that the S100A14 expression level was a significant and independent prognostic factor for overall survival (OS) of HCC patients (hazard ratio=1.98, 95% confidence interval=1.14-3.46, P=0.013). S100A14 promoted cell proliferation, invasion and metastasis of HCC in vitro and in vivo. Conclusion: These results suggest S100A14 is a novel prognostic marker and therapeutic target for HCC.

  • In spite of the attention given to the study of mesenchymal stem cells derived periodontal ligament (PDL), there is a lack of information about canine PDL cells. In this study, we characterized canine PDL cells to clarify their stem cell properties, including self renewal, proliferate rate, stem cell markers and multipotency. PDL cells were obtained from extracted premolars of canines, following a colony forming assay and proliferation rate of sub-confluent cultures of cells for self-renewal, immunostaining for STRO-1 and CD146/MUC18 and a differentiation assay for multipotency. Canine PDL cells formed single-cells colonies and 25% of the PDL cells displayed positive staining for BrdU. The cells expressed the mesenchymal stem-cell markers, STRO-1 and CD146/MUC18. Under defined culture conditions, the cells differentiated into osteoblasts and adipocytes, but the cells didn't differentiated into chondrocytes. The findings of this study indicated that the canine PDL cells possess crucial stem cells properties, such as self-renewal and multipotency, and express the mesenchymal stem cell markers on their surface. The isolation and characterization of canine PDL cells makes it feasible to pursue preclinical models of periodontal regeneration in canine.
