  • Objective : For various reasons, Obesity & Rhinitis are constantly rising. So Interest of treatment has been expanding. We want to verify The Chungyeol (fire extinguishing) Lisup (Draining) effect of Bangpungtongsungsan on obese model of allergy rhinitis.Material and Methods : BALB/c mouse were divided four groups: control(CON), allergic induction(ARE), Bangpungtongsungsan extract administration(BTT), Bangpungtongsungsan double concentration extract administration (BT2T). Every group except control group were caused allergic rhinitis by Ovalbumin. BTT & BT2T were orally administered the Bangpungtongsungsan for 21days. Since then we observed the liver tissue cell and the nasal mucous membrane.Results : In comparison with ARE, experimental groups show relief of the nasal mucous membrane damage(secretion of mucus decrease, Itching decrease), Th2 eruption control(IL-4 decline), effect of anti-inflamatory(reducing TNF-α creation, decreasing of iNOS through NF-κB activation-inhibition). In addition, experimental groups show a loss in weight, diminished accumulation of fat. (decreasing within liver tissue, reducing TNF-α creation) BT2T is more effective to BTT.Conclusion : Bangpungtongsungsan treat obese model on allergy rhinitis thereby control fat augmentation, relieving inflammation.

  • Purpose : This study was undertaken to obtain basic data about the megakaryocyte colony formation of fetal liver cells by using immunocytochemical staining and ex vivo culture with growth factors. Methods : The mononuclear cells were isolated from fetal liver and bone marrow with idiopathic thrombocytopenic purpura(ITP) and pancytopenia. These mononuclear cells were cultured in $MegaCult^{TM}-C$(Stem Cell Tech, Canada) media in the presence of growth factors and CFU-Megakaryocyte( CFU-Mk) colonies were counted on day 12. The expansion of CD34+ and CD41+ cell was analyzed by flow cytometry after 5 days incubation using flask culture. Results : The numbers of CFU-Mk colonies of mononuclear cells obtained from fetal liver in the 11th week gestational age were more than those in the 19th week specimens; growth factors could not enhance the colony expansion in all cases. Total numbers of CFU-Mk colony of fetal liver cells were higher than bone marrow from ITP or pancytopenia groups. The numbers of pure or large CFU-Mk colonies of fetal liver cells were also higher than bone marrow specimens. The rate of CD34+ cell expression of fetal liver was increased after flask culture and the enhancement effect of epression was seen only in cases which added thrombopoietin. The rate of CD41+ cell expression of fetal liver was increased after incubation, but the enhancement effect of growth factors was unclear. Conclusion : This study revealed good results about the megakaryocyte colony assay of fetal liver mononuclear cells using $MegaCult^{TM}-C$ media. This study suggests that the fetal liver could be a good source of megakaryocytic progenitor cells for clinical application in hematopoietic stem cell transplantation.

  • 1. About fifty thousand of cattle embryos were transferred and 16000 ET-calves were born in 1999. Eighty percents of embryos were collected from Japanese Black beef donors and transferred to dairy Holstein heifers and cows. Since 1985, we have achieved in bovine in vitro fertilization using immature oocytes collected from ovaries of slaughterhouse. Now over 8000 embryos fertilized by Japanese Black bull, as Kitaguni 7~8 or Mitsufuku, famousbulls as high marbling score of progeny tests were sold to dairy farmers and transferred to their dairy cattle every year. 2. Embryo splitting for identical twins is demonstrated an useful tool to supply a bull for semen collection and a steer for beef performance test. According to the data of Dr. Hashiyada(2001), 296 pairs of split-half embryos were transferred to recipients and 98 gave births of 112 calves (23 pairs of identical twins and 66 singletons). 3. A blastomere-nuclear-transferred cloned calf was born in 1990 by a joint research with Drs. Tsunoda, National Institute of Animal Industry (NIAI) and Ushijima, Chiba Prefectural Farm Animal Center. The fruits of this technology were applied to the production of a calf from a cell of long-term-cultured inner cell mass (1988, Itoh et al, ZEN-NOH Central Research Institute for Feed and Livestock) and a cloned calf from three-successive-cloning (1997, Tsunoda et al.). According to the survey of MAFF of Japan, over 500 calves were born until this year and a glaf of them were already brought to the market for beef. 4. After the report of "Dolly", in February 1997, the first somatic cell clone female calves were born in July 1998 as the fruits of the joint research organized by Dr. Tsunoda in Kinki University (Kato et al, 2000). The male calves were born in August and September 1998 by the collaboration with NIAI and Kagoshima Prefecture. Then 244 calves, four pigs and a kid of goat were now born in 36 institutes of Japan. 5. Somatic cell cloning in farm animal production will bring us as effective reproductive method of elite-dairy- cows, super-cows and excellent bulls. The effect of making copy farm animal is also related to the reservation of genetic resources and re-creation of a male bull from a castrated steer of excellent marbling beef. Cloning of genetically modified animals is most promising to making pig organs transplant to people and providing protein drugs in milk of pig, goat and cattle. 6. Farm animal cloning is one of the most dreamful technologies of 21th century. It is necessary to develop this technology more efficient and stable as realistic technology of the farm animal production. We are making researches related to the best condition of donor cells for high productivity of cloning, genetic analysis of cloned animals, growth and performance abilities of clone cattle and pathological and genetical analysis of high rates of abortion and stillbirth of clone calves (about 30% of periparutum mortality). 7. It is requested in the report of Ministry of Health, labor and Welfare to make clear that carbon-copy cattle(somatic cell clone cattle) are safe and heathy for a commercial market since the somatic cell cloning is a completely new technology. Fattened beef steers (well-proved normal growth) and milking cows(shown a good fertility) are now provided for the assessment of food safety.

  • Objectives: The purpose of this study is to investigate the effects of Yijungtang(YJT) on atopic dermatitis in an in-vitro and in-vivo experiment using a RBL-2H3 mast cells and a NC/Nga atopic dermatitis mouse. Methods: In-vitro experiment, IL-4, IL-13 mRNA expression were evaluated by a real-time PCR, IL-4, IL-13 production by ELISA and transcription factor as GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-kB by western blotting. In-vivo experiment, clinical skin score we evaluated by, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mouse, cytokine level, total number of cell, Immunohistochemical staining and Histological features of auxiliary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue in NC/Nga mouse. Results: YJT decreased IL-4, IL-13 mRNA expression, IL-4, IL-13 production and prominently decreased the expression of mast cell specific transcription factors including GATA-2, NF-AT2, c-Fos and NF-kB. YJT oral administration reduced the levels of skin severity scores. It also decreased the level of inflammatory cytokines such as IL-5, IL-13, histamine and IgE in the serum. It elevated IFN-gamma level in the spleenocyte culture supernatant but decreased. $CD3e^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $CD11b^+Gr-1^+$, $CCR3^+$ in the PBMCs, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $B220^+CD23^+$ in the ALN, $CD4^+$, $CD3e^+CD69^+$ in the ALN and $CD4^+$, $CD11b^+Gr-1^+$ in the dorsal skin. Histological examination showed that infiltration levels of immune cells in the skin of AD-induced NC/Nga mice were much improved by YJT oral administration. Conclusions: The anti-allergic activities of YJT may be mediated by down-regulation of Th2 cytokines, such as IL-4 and IL-13, through the regulation GATA-2, NF-AT2 and NF-kB transcription factors in mast cells. YJT would be regulate molecular mediators and immune cells which are functionally associated with atopic dermatitis induced in NC/Nga mice, and may play an important role in recovering AD symptoms.

  • Main strategy for a treatment of Parkinson's disease (PD), due to a progressive degeneration of dopaminergic neurons, is a pharmaceutical supplement of dopamine derivatives or ceil replacement therapy. Both of these protocols have pros and cons; former exhibiting a dramatic relief but causing a severe side effects on long-term prescription and latter also having a proven effectiveness but having availability and ethical problems Embryonic stem (ES) cells have several characteristics suitable for this purpose. To investigate a possibility of using ES cells as a carrier of therapeutic gene(s), human ES (hES, MB03) cells were transfected with cDNAs coding for tyrosine hydroxylase (TH) in pcDNA3.1 (+) and the transfectants were selected using neomycin (250 $\mu /ml$). Expression of TH being confirmed, two of the positive clone (MBTH2 & 8) were second transfected with GTP cyclohydrolase 1 (GTPCH 1) in pcDNA3.1 (+)-hyg followed by selection with hygromycin-B (150 $\mu /ml$) and RT-PCR confirmation. By immune-cytochemistry, these genetically modified but undifferentiated dual drug-resistant cells were found to express few of the neuronal markers, such as NF200, $\beta$-tubulin, and MAP2 as well as astroglial marker GFAP. This results suggest that over-production of BH4 by ectopically expressed GTPCH I may be involved in the induction of those markers. Transplantation of the cells into striatum of 6-OHDA- denervated PD animal model relieved symptomatic rotational behaviors of the animals. Immunohistochemical analyses showed the presence of human cells within the striatum of the recipients. These results suggest a possibility of using hES cells as a carrier of therapeutic gene(s).

  • Objectives: Radiation is one of the most important sources of free radical (such as reactive oxygen species) production, which plays an essential role in the etiology of over hundred diseases. The aim of the study was to investigate some immune parameters and hematological indices in healthy workers of the Radiology Department, University Hospital of Mashhad, Iran. Methods: The study was performed on 50 healthy workers: 30 radiology staff as the case group and 20 laboratory workers as the control group. The radiation dose received by the radiology staff participating in the study was less than the annual maximum permissible level, 50 millisievert. Hematological parameters, lymphocyte proliferation and cytokine production were studied in both groups. Results: Among healthy radiology workers, the hematological indices did not differ statistically; however, their proliferation indices and $IFN-{\gamma}$ levels showed significant increases in parallel with decreases in the IL-4 levels as compared to controls. The immune system of workers exposed to low-dose ionizing radiation was found to be shifted from a Type 2 to a Type 1 response to promote cellular immunity. Conclusion: Based on our data, exposure to low-dose ionizing radiation may decrease the prevalence, frequency, and recurrence of various cancers and infectious diseases because of an increase in Th1-cell-based response, thus leading to more protection of the human body against tumor cells and foreign agents and possibly increased longevity. However, due to high rate of fluoroscopy use for interventional radiology, we suggest continuing research projects on radiation protection and hazards to prevent irreversible damage. As a recommendation, in future studies, radiology staff with a weakened immunity due to high radiation exposure should be considered as good choices to be treated using acupuncture techniques because acupuncture has been demonstrated to enhance the function and the number of immune cells.

  • Objective : This study was undertaken to investigate effects of Opuntia ficus-indica (OP)extract on an asthma murine model. Methods : The total number of cells and eosinophils in BALF and the infiltration of inflammatory cells into lung tissues were determined by hematoxylin and eosin staining. Results : The number of OVA-induced total cells and eosinophils, a phenomenon of asthma, were decreased by treatment of the animals with OP extract (200 mg/kg) (respectively, p < 0.001 and p<0.01). Furthermore, we showed that OP extract reduced the increased immune cell infiltration induced by ovalbumin (p < 0.01). The levels of interleukin (IL)-4 in BAL fluid were measured by enzyme-linked immunosorbent assay, because the eosinophilia is associated with a T helper (Th) 2 response including IL-4. The level of OVA-induced IL-4 was decreased by OP extract in BAL fluid (p < 0.05). We investigated whether OP extract reduced nitrite (NO) production on lipopolysaccharide (LPS)-stimulated RAW 264.7 sells, because asthma is an inflammatory disease. The level of LPS-induced NO production was decreased by OP extract (50, 100 and 200 mg/ml) on RAW 264.7 cells (respectively, p < 0.05, p<0.01 and p<0.05). Conclusions : Our results indicate that OP extract has an inhibitory effect on lung eosinophilia of asthma and suggest that OP extract is a therapeutic candidate in the treatment of inflammatory disease, including asthma.

  • The purpose of this study was to evaluate the difference of differentiation potential in each passage of dental pulp stem cells from supernumerary tooth (sDPSCs). The sDPSCs were obtained from a healthy 6-year-old male patient under the guidelines and got the informed consent. Cells were cultured until passage number 16 and divided into two groups; 1 - 8 passages as a young group and 9 - 16 passages as an old group. It was taken $2.25{\pm}0.46days$ in a young group and $3.25{\pm}0.46days$ in an old group to propagate cells of each passage until confluence and there were statistically significant differences between two groups (p < 0.05). In every passage, cell morphology was observed with microscope and evaluated the capacity to form high levels of minerals by alizarin red solution staining after treating differentiation medium. Fibroblast-like, spindle shaped, elongated cells and a few nodules were found in uninduced cultures of passage number 1, 8 and 9. But at 16 passage culture, cell size became larger and broader and observed with more nodules. After inducing differentiation, mineralized nodules were detected at the first passage of 7th day culture whereas at the 8 passage culture, nodules were seen clearly at 14th day culture. In addition, the amount of mineralized nodules were remarkably decreased after passage 9. From the data presented in this study, it is recommended to use sDPSCs of passage number within 8 for utilizing as stem cells.

  • One of the most extensively studied populations of multipotent adult stem cells are mesenchymal stem cells (MSCs). MSCs derived from the human umbilical cord vein (HUC-MSCs) are morphologically and immunophenotypically similar to MSCs isolated from bone marrow. HUC-MSCs are multipotent stem cells, differ from hematopoietic stem cells and can be differentiated into neural cells. Since neural tissue has limited intrinsic capacity of repair after injury, the identification of alternate sources of neural stem cells has broad clinical potential. We isolated mesenchymal-like stem cells from the human umbilical cord vein, and studied transdifferentiation-promoting conditions in neural cells. Dopaminergic neuronal differentiation of HUC-MSCs was also studied. Neural differentiation was induced by adding bFGF, EGF, dimethyl sulfoxide (DMSO) and butylated hydroxyanisole (BHA) in N2 medium and N2 supplement. The immunoreactive cells for $\beta$-tubulin III, a neuron-specific marker, GFAP, an astrocyte marker, or Gal-C, an oligodendrocyte marker, were found. HUC-MSCs treated with bFGF, SHH and FGF8 were differentiated into dopaminergic neurons that were immunopositive for tyrosine hydroxylase (TH) antibody. HUC-MSCs treated with DMSO and BHA rapidly showed the morphology of multipolar neurons. Both immunocytochemistry and RT-PCR analysis indicated that the expression of a number of neural markers including NeuroD1, $\beta$-tubulin III, GFAP and nestin was markedly elevated during this acute differentiation. While the stem cell markers such as SCF, C-kit, and Stat-3 were not expressed after neural differentiation, we confirmed the differentiation of dopaminergic neurons by TH/$\beta$-tubulin III positive cells. In conclusion, HUC-MSCs can be differentiated into dopaminergic neurons and these findings suggest that HUC-MSCs are alternative cell source of therapeutic treatment for neurodegenerative diseases.

  • Tuna cooking juice concentrate (TCJC) is by-produced during the canning processing of skipjack tuna Katsuwonus pelamis and it is well known that TCJC contains various nutritional components. Therefore, the immuno-stimulating activity of TCJC was investigated using macrophage RAW 264.7 cell line and the spleen cell isolated from BALB/c mice. The TCJC increased the production of IL-6, TNF-${\alpha}$, and IL-$1{\beta}$ in a dose-dependent manner compared to the control in RAW 264.7 cells without any toxicity. In particular, the production of TNF-${\alpha}$ was increased over 300-fold. The production of both Th1 cytokine (such as IFN-${\gamma}$, TNF-${\alpha}$, IL-2, and IL-12) and Th2 cytokine (IL-4, IL-6, IL-10) was also increased by TCJC treatment in splenocytes. Moreover, the TCJC increased the splenocyte proliferation in a concentration-dependent manner compared to control. These results indicate that TCJC may enhance immune function by promoting various cytokine production.
