  • The aim of this study is to evaluate the anti-inflammatory effect of Hataedock treatment using Coptidis Rhizome and Glycyrrhiza Uralensis (CG) mixed extract in allergic rhinitis induced NC/Nga mice. We divided NC/Nga mice into 3 groups as follows; allergic rhinitis-induced group after CG Hataedock treatment (CGT, n=10), no treatment group (Ctrl), allergic rhinitis elicited group (ARE). To induce allergic rhinitis, NC/Nga mice of 3 weeks age were sensitized on 7, 8 and 9week by Ovalbumin (OVA) antigen in intranasal space. Hataedock using CG extract was administered on week 3 in allergic rhinitis-induced group (CGT) after Hataedock treatment. To identify distribution of Interlukin (IL)-4, Cluster of differentiation 40 (CD40), high-affinity IgE receptor ($Fc{\varepsilon}RI$), substance P, Matrix metallopeptidase 9 (MMP-9), Nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) p65, Inducible nitric oxide synthase (iNOS) and Cycloxygenase-2 (COX-2), we used histological examination. CGT significantly inhibited IL-4 and CD40 response compared with ARE. The reduction of Th2 cytokine expression decreased inflammatory mediators such as $Fc{\varepsilon}RI$, substance P, MMP-9, $NF-{\kappa}B$ p65, iNOS and COX-2. Such immunological improvement induced reduction of respiratory epithelial damage and mucin secretion in goblet cell. These results indicate that Hataedock treatment suppresses allergic rhinitis through modulating of Th2 responses and diminishing various inflammatory mediators in nasal mucosal tissue. It might have potential applications for prevention and treatment of allergic rhinitis.

  • Purpose: An ideal bony construct can be divided into two broad categories: (1) the design and fabrication of biodegradable, biomimetic scaffolds that provide correct signals to induce osteogenesis: (2) the identification of an ideal source of osteoprogenitor cells to seed onto the scaffold. We selected poly-glycolic acid as a synthetic scaffold among various scaffolds because of these properties. Meanwhile, culture medium is supplemented with fetal bovine serum(FBS): such serum contains essential elements such as proteins, hormones, growth factors and trace minerals. The composition of FBS can be ideal for various cell growth in vitro. We supposed that we could enhance bone growth at a fractured site if FBS was mixed with synthetic scaffold-PGA. Methods: We cultured human osteoblasts in five different prepared culture dishes made with FBS and PGA mixture. The mixtures contained different ratio of FBS, that is, 0, 1.5, 3, 7, and 10%. We cultured human osteoblasts for seven days and examined the growth and attachment of the cells at the 1st, 3rd, 5th, 7th days, respectively. Results: In the mixture of 0% FBS and PGA, the growth of the cells lasted for one day. In 1.5 and 3% FBS and PGA, the growth of the cells was examined at the 3rd day, then minimally declined at the 5th and 7th days. In 7% FBS and PGA, the growth of the cells lasted for 5 days, then declined at the 7th day. In 10% FBS and PGA, the growth of the cells lasted for 5 days, then declined at the 7th day. Staining status of the osteoblasts with alkaline phosphatase showed pale pink color in 0% FBS and PGA groups, but bright pink color in 1.5, 3, 7, 10% FBS and PGA groups, especially in 3%, 7%. Conclusion: In consequence, the growth of human osteoblast was higher in the mixture of FBS and PGA groups than in pure PGA ones. It is assumed that the mixture of FBS and PGA affects the proliferation of human osteoblasts.

  • GMI (Fibrel${(R)}$) is one of the dermal filling substances which have been successfully used for the treatment of depressed cutaneous scar and wrinkles. It's major components are; Gelatin powder, which provides a framework for the clot to form and remains stable under the scar, and ${\varepsilon}$-aminocaproic acid, which inhibits the production of fibrinolysin, and Plasma, which provides the necessary ingredients for collagen synthesis. GMI has advantages of low immunogenicity and increased longevity. It has been known to induce fibroblast activity and promote new collagen synthesis. We used 34 Sprague-Dawley rats which were bred under the same condition and duration. 18 of experimental animals were undergone cardiac puncture, and their blood were collected, centrifugated, and stored in freezer. Out of 16 animals, control group were injected with 2ml plasma into the subcutaneous tissue of Lt. scapular, while experimental group were implanted of 2 ml GMI into the Rt. same area. Experimental animals were sacrificed at the 3rd day, 5th day, 1st week and 2nd week respectively after implantation of GMI. To observe the histopathologic change of GMI and surrounding tissue reaction of GMI, we had examined with H&E staining, immunohistochemical staining with vimentin, ${\alpha}$-SMA, S-100 under LM and SEM. The obtained results were as follows ; 1. In LM study, the inflammatory cell infiltrations and granulation tissue formation were observed, and muscle tissues were well attached with adipose tissues in the control group. In the experimental group, inflammatory cell infiltrations had been observed by the 2nd week and irregular adipiose tissues and well differentiated mesenchymal tissues were examined. 2. In immunohistochemical study, the experimental group of ${\alpha}$-SMA study, there were a prominent positive response on endothelial development of granulation tissues and mesenchymal tissues compare with the control group. In vimentin study, positive response on mescenchymal fibroblast continued to 2nd week, but negative in the control group. In S-100 study, both groups were positively responded on irregular adipose tissues. 3. In SEM study, collagen fibers were embedded by the plasma by the 5th day in the control group, and in the 3rd day experiment GMI were resorved but communited with collagen fiber till the 1st week. Collagen fibers were infilt-rated into GMI at the 2nd week and the infilltrated GMI were conglomerated with the mature adipose cells and the collagen fibers. From the above results, GMI implantation in the subcutaneous tissue of Sprague-Dawley rat, the mild infiltration of inflammatory cells were showed till 2nd week and the granulation tissues were observed. GMI were nearly resorbed till 2nd week, but well attached with adipose tissue and collagen fibers. The endothelium and fibroblasts were actively proliferated. Adipose tissues and mesenchymal tissue cells were observed. As already expressed, GMI showed resorptive change in course of time without any early immune reaction, and seemed to induce fibroblast activity and promote new collagen synthesis.

  • We investigated the immunomodulatory actions of water extract from Acanthopanax senticosus in male ICR mice. The mice were treated with fermented milk containing three added doses of freeze dried extract: 3 mg/kg (A), 9 mg/kg (B), and 27 mg/kg (C) of body weight with Acanthopanax senticosus: Codonopsis lanceolata (8:2) for 7 and 10 weeks, respectively. Organ weights, plaque-forming cell tests, agglutination tests, IgG tests, differential white cell counts, and histological tests were performed at the 7th and 10th weeks of dietary treatment. There were no significant differences in body weight and organ weight. The spleen indices of group B at 7 weeks and group C at 10 weeks were significantly higher than those of the control group (p<0.05). For the plaque-forming cell test, groups B and C at 7 weeks, and group C at 10 weeks, showed significant increases over the control group (p<0.05). The agglutination test decreased with an extended experimental period. Groups A, B, and C at 7 weeks, and groups B and C at 10 weeks, had greater antibody responses to sheep red blood cells (SRBC) than the control group. The IgG antibody production of group C at 7 weeks and groups B and C at 10 weeks were significantly higher than the control group (p<0.05). In groups B and C, lymphocyte percentage was higher than the control group, and their spleen and thymus tissues showed active immune reactions.

  • The Immunoglobulin $IgG_1$ and $IgG_2$ isotype immune responses of domestic ruminants and mice to Cowdria. ruminantium live infection or by immunization with inactivated organisms were determined by the enzyme linked immunosorbent assay and Western blotting. Immunization of goats with inactivated elementary bodies (IEBs) led to a predominant $IgG_1$ isotype response. This indicated that a Th2 response was induced. After challenge, the IgG isotype responses were mixed whereby both $IgG_1$ and $IgG_2$ antibodies were detected. Two goats that survived virulent challenge had a predominant $IgG_2$ isotype response. In cattle live infection by natur l challenge or experiment led to a predominant $IgG_1$ isotype response. Immunization of cattle with IEBs however led to mixed IgG responses characterized by similar $IgG_1$ and $IgG_2$ ratios. In the mouse live infection led to a predominant $IgG_2$ isotype response. This indicated the mouse developed a true Th1 type cell mediated immune response when inoculated with live organisms. Immunization with inactivated organisms on the other hand led to a dominant $IgG_1$ response. It is evident from this work that the immune responses of ruminants and mice to C. ruminantium are different and that using mice as the experimental model for immune responses to Cowdria ruminantium. is not the appropriate.

  • The purpose of this study is to evaluate an efficacy of in vitro differentiated human embryonic stem (hES, MB03) cells expressing Nurr1 in relief of symptomatic motor behavior of Parkinson's disease (PD) animal models MB03 was genetically modified to express Nurr1 protein and was induced to differentiate according to 2-/4+ protocol using retinoic acid and ascorbic acid. The differentiation-induced cells were selected for 10 to 20 days thereafter in N2 medium. Upon selection, cells expressing GFAP, TH, or NF200 were 38.8%, 11%, and 20.5%, respectively. in order to examine therapeutic effects of the differentiated cells in PD animal model, rats were unilaterally lesioned by administration of 6-kydroxydopamine HCI (6-OHDA) into medial forebrain region (MFB, AP -4.4 mm, ML 1.2 mm, DV 78 mm with incision bar set at -2.4 mm), as a reference to bregma and the surface of the skull. Confirmation of successful lesion by apomorphine-induced rotational behavior, differentiated cells were transplanted into the striatum (AP 1.0, ML 3.5, DV -5.0; AP 0.6, ML 2.5, DV -4.5). Improvements of asymmetric motor behavior by the transplantation were examined every two weeks after the surgery. In two weeks, numbers of rotation by the experimental rats were $-14.8 \pm 33.9%$ (P<0.05) of the number before transplantation, however, the ratio increased slightly to $13.6 \pm 56.3%$ in six weeks. In contrast, the ratio of sham-grafted animals ranged from 112.3+8.5% to 139.2+28.9% during the examination. Immunohistochemical studies further confirmed the presence, survival, migration, and expression of TH of the transplanted human cells.

  • The optimum liquid culture conditions were investigated for cell growth and polysaccharide production from liquid culture of Lentinus edodes. In flask culture, the optimal medium compositions for the polysaccharide production contained glucose 60 g/L, yeast extract 10 g/L, $KH_2PO_4$ 2.0 g/L, and $MgSO_4{\cdot}7H_2O$ 1.0 g/L. The maximum mycelial growth and polysaccharide production were 11.01 g/L and 1.64 g/L, respectively. In bioreactor, through the variation of aeration in order to increase mycelial growth and polysaccharide production, the maximum mycelial growth and polysaccharide production were 55.9 g/L at 8th day and 7.34 g/L at 7th day of cultivation with 1.5 vvm, respectively.

  • Objective : Although management of asthma has become increasingly effective, its cure remains elusive, necessitating a new modality to prevent or eliminate causes triggering clinical progress. Based in the clinical experiences, a novel decoration Cheongsangbiyeum (CSB), has been developed to treat asthma, which consists of Polyporus, Semen Myristicae, Pericarpium citri Reticulatae, Rhizoma Cimicifugae, Cortex Albizziae, Fructus Rubi, Rhizoma Zedoariae, and Rhizoma Rhei. In the current study, its anti-asthmatic efficacy was evaluated using a mouse model of asthma. Methods : Experimental allergic asthma was induced by repeated intraperitioneal sensitization and intranasal challenge of ovalbumin (OVA). Water extract of CSB (1 mg/mouse/day) was administrated orally whereas control mice on given with identical volume of phosphate-buffered saline (PBS) for 5 days during the course of antigen challenge. When airway hyperreactivity(AHR) measured by ${\bata}-methacoline-induced$ airflow obstruction was compared, AHR of CSB-treated mice was significantly lower than those of control mice, indicating that CM extract can attenuate an asthmatic symptom. Airway recruitment of leukocytes and eosinophils was also markedly reduced by CSB treatment suggesting that oral treatment of CSB can alleviate the airway inflammation. For a better understanding of possible mechanisms underlying anti-asthmatic effet of CSB, cytokine (IL-4, IL-5, IL-13 and $IFN{\gamma}$ levels in bronchoalveola lavage fluid (BALF) and lung tissues were determined. Results : The results showed that cytokine levels were significantly lowered by CSB treatment. Additionally, number of draining lymph node cells was significantly lower than those of control mice. These data indicate that CSB suppress in vivo allergen-specific response. However, notably, levels of type 2 cytokines such as IL-5 and IL-13 were more profoundly influenced. Moreover, in vitro OVA-specific proliferative response and type 2 cytokine (IL-4, IL-5 and IL-13) production lymph node cells was markedly decreased in CSB-treated mice, whereas their $IFN{\gamma}$ production was not significantly altered Thrse data clearly showed a preferential inhibition of type 2 T cell (Th2) response by CSB treatment. This finding was also supported by serum antibody data showing that levels of OVA-specific type 2 antibodies, IgE and IgG1, in CSB-treated mice were significantly lower than in control mice, while type 1 antibody, IgG2a level m rather higher than controls, although the difference was in significant. Conclusions : In conclusion, oral administration of CSB attenuates asthmatic manifestations including AHR ad airway recruitment of eosinophils in a mouse model which possibly results from selective inhibition of Th2 cell response to allergen. Our data suggest a potential clinical application of CSB for control of allergic asthma.

  • Angiogenesis is an essential process for the growth, invasion and metastasis of cancer. However, it is uncertain that antiangiogenic effects can be a major treatment strategy of oral cancer. The aim of this study was to investigate whether thalidomide, which is known to be a potent inhibitor of angiogenesis, have inhibitory effect on the growth and antiangiogenic effects of oral squamous cell carcinoma(OSCC) xenografted in nude mice and whether antiangiogenesis of thalidomide can be included as a major treatment strategy of oral cancer. After human oral squamous cell carcinoma strain KB was subcutaneously implanted in 20 nude mice, the volume of tumor was measured every three days. When the tumor mass reached $75{\sim}100mm^3$, thalidomide(200mg/kg/d) was administered into 10 experimental nude mice and the same volume of distilled water was administered into 10 control nude mice and the tumor volume was measured every three days. The excised tumor masses on the 30th day after administration were frozen and processed for immunohistochemistry using vascular endothelial growth factor(VEGF) and CD31. We evaluated microvessel density and VEGF expression. The results were as follows ; 1. Thalidomide retarded the growth of human OSCC as compared with the control group, but it was not statistically significant. 2. A statistically significant lower microvessel density was observed in the thalidomide-treated group than in the control group(p<0.01) and thalidomide significantly reduced VEGF expression (p<0.01). Thalidomide exhibited significantly antiangiogenic effect, but did not inhibit the growth of human OSCC effectively. Antiangiogenic therapy of thalidomide alone is not likely to be effective in the treatment of human OSCC, but might be regarded as adjuvant chemotherapeutic strategy.

  • The records of 65 patients with a confirmed diagnosis of primary lung cancer who underwent surgical therapy at the Department of Thoracic and Cardiovascular Surgery of the Keimyung University Hospital were analyzed during the period of 8 years and 4 months, from August, 1978 to December, 1986. The peak incidence was observed in the 5th decade of life and the mean age was 52.9 years old. Male versus female ratio was 8.3:1 Cough was the most frequent presenting symptom, 76.9% then chest discomfort, hemoptysis and dyspnea followed in order. 44.6% of the patient had 2 months of prediagnostic symptomatic period, 72.3% had 5 months, and the mean was 5.7 months. As for preoperative diagnosis, 62 of total 65 patients revealed the mass lesion on simple chest x-ray, and 56 of 65 patients on bronchoscopic biopsy, 10 of 37 patients on sputum cytology and 15 of 15 patients on computerized tomography of the chest were positive. Of the 65 patients, 35 [53.9%] had squamous cell carcinoma, 18 [27.7%] adenocarcinoma, 3 [4.6%] large cell carcinoma, and 3 [4.6%] small cell carcinoma all which was oat cell carcinoma. 83.1% of the total patient was resectable, and 34 underwent pneumonectomy and 20 lobectomy. Of these 65 operations, 29 was radical resection, 25 palliative, and 11 exploratory thoracotomy. As for clinical stagings, 23 patients were in Stage, I, another 23 in Stage II and 19 in Stage III, while 16 was in stage, I, 14 in stage ll and 35 in stage III in postoperative staging evaluation. In correlation of postoperative TNM classification and radical resection, those patients who had lung cancer of stage I [14/16] and stage II [9/13] had more radical resection. As postoperative complications, one patient had massive bleeding, two empyema, one empyema with bronchopulmonary fistula, and one cardiac herniation. Operative mortality rate was 1.5% [1 patient]. Mean duration between 1st operation and discovering recurrence in 18 patients was 12.7 months.
