Objectives : The aim of this study was to know the immunity reponse of Esubwhaltong-tang(hereafter referred to ESWTT) to rheumatoid arthrits in CIA(collagen induced arthritis) mice. Methods : For this purpose, ESWTT was orally administerd to mice with arthritis induced by collagen II and then value of immunocyte in paw joint, cytokine(IL-6, $TNF-{\alpha}$), rheumatoid factor(IgG and IgM) and collagen II specific antibody in the serum were measured. Results : 1. The cytotoxicity was not shown on hFLSs and liver. 2. Marginal erosion, necrotic chodrocytes, cartilage and bone degradation were improved in histological section of paw joints from CIA mice(ESWTT extract administration group). 3. Total cell number of paw joint in CIA mice(ESWTT extract administration group) was decreased significantly. 4. The absolute number of CD3+, CD3+/CD69+, CD4+, CD4+/CD25+, CD49b+, CD3+/CD49b+ cells in CIA mice(ESWTT extract administration group) were decreased significantly. 5. The levels of IL-6 and $TNF-{\alpha}$ in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 6. The levels of total IgG and IgM in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 7. The level of collagen II specific antibody in the serum of CIA mice(ESWTT extract administration group) was decreased significantly. Conclusions : Comparison of the results for this study showed that ESWTT had immunomodulatory effects of suppressing. So we expect that ESWTT could be used as an effective drugs for not only rheumatoid arthritis but also auto-immune disease.

This study classified 40 of 10 weeks-old male Sprague Dawley rats which have osteoporosis caused by glucocorticoid(GC) induction into four groups of 10 rats and made the subjects medicated them Eucommia ulmoides Oliver and participate in treadmill exercise. Group I was non-treatment after GC induction; Group II was treadmill exercise after GC induction; Group III was Eucommia ulmoides Oliver feeding after GC induction; Group IV was treadmill exercise and Eucommia ulmoides Oliver feeding after GC induction. In the bone mineral density and bone strength test, there was a statistically significant difference between the group I, II, III compared to group IV(p<0.05). In the osteocalcin level as one of bone formation indexes, there was a statistically significant difference between the group I, II, III compared to group IV(p<0.05). In respect to the calcium there was a statistically significant difference between group I, II, III compared to group IV(p<0.05). In respect to histological findings, the group IV showed mild femur disruption and lytic change on femur section. The above results suggests that Eucommia ulmoides Oliver medicated and treadmill exercise is effective to prevention and treatment of osteoporosis.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.

In recent years, numerous researches have been carried out in author's laboratory to develop several kinds of methods for producing transgened chicken, leaving a lot of new findings. Some of them are very useful to search for new approaches necessary to improve the efficiency of hatchability and the survival rate of developing trasgened embryos. The results obtained hitherto might be summarized as follows: (1) foreign gene(Lac Z/ Miw Z) introduced into blastodermal cells of developing embryos was successfully transferred to embryos, leading to the production of primordial germ cells(PGCs) carrying foreign DNA. However, hatched hickens failed to show the incorporation of introduced gene into the gonads. (2) When foreign gene was introduced into germinal crescent region (GCR), the gene was also efficiently incorporated into germ cells, resulting in the production of transgened chickens(offspring) which produced fruther offspring having foreign gene in the gonads. In this case, 2nd and 3rd generations of chickens were obtained through the reproduction of transgened birds. (3) In another way, the gene was injected into blood vessels of developing embryos at stage 13∼15, creating PGCs having foreign gene, and produced some transgened chickens. In this work, the PGCs were transfered between embryos, resulting in the production of transgenic chickens. (4) in these experiments, PGCs were effectively employed for producing transgenic birds, developing some kinds of chimeric chickens from homo- or hetero-sexual transfer of the PGCs from embryos. This means that the gonads from donor PGCs developed in some degree to the stage of hatching. However, these gonads showed slightly abnormal tissues similar to ovotestis like organs through histological examination. (5) Avian Leukosis Virus(ALV) induced B cell line(DT40) successfully carried foreign genes into chicken embryos, suggesting the possibility of the cells as a vector in this field of study in the future. (6) Inter-embryonic transfer of the PGCs also gave us some.

Alcohol abuse and its medical and social consequences are a major health problem in many areas of the world. The present study was conducted to evaluate the protective effect of methanolic fruit extract of $Randia$ $Dumetorum$ (L.) on alcohol-induced liver damage in rats. Rats were divided into five different groups (n=6), group I served as a control, group II received ethanol (3 ml/100 g/day p.o.), group III served as standard group and received silymarin (50 mg/kg p.o.), group IV and V served as extract treatment groups and received 50 & 100 mg/kg methanolic extract of $R.$ $dumetorum$. All the treatment protocols followed 30 days and after rats were sacrificed blood and liver were used for biochemical and histological studies, respectively. The activities serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), direct bilirubin (DB), total bilirubin (TB) and lipid peroxidation were statistically increased in rats exposed to alcohol while total protein and glutathione decreased compared to control rats. Treatment with $R.$ $dumetorum$ significantly decreased the elevated levels of ALT, AST, TG, DB, TB and lipid peroxidation compared to the group exposed to alcohol only. $R.$ $dumetorum$ significantly resulted in increased levels of total protein and reduced glutathione compared to the group that received alcohol only. Histology of the liver section of the animals treated with $R.$ $dumetorum$ improved the hepatotoxicity caused by alcohol. Hence the study concluded that $R.$ $dumetorum$ has potential hepatoprotective activity.

This study was carried out to know the immunological effect of GDGT on CIA(collagen induced arthritis) mice, a model of rheumatoid arthritis. For this purpose, GDGT was orally administerd to mice with arthritis induced by collagen II and then value of cytotoxicity on hFLSs and liver, the arthritis index, immunocyte in paw joint and DNL, rheumatoid factor (IgG and IgM), collagen II specific antibody in the serum were measured. The cytotoxicity were not shown on hFLSs and liver. The arthritis index decreased significantly after 3 week. In total cell counts of DLN and paw joint, there was a significant increase in DLN and significant decrease in paw joint. In DNL, $CD19^+$, $CD3^+$, $CD4^+$, $CD3^+/CD69^+$, $CD8^+$, $CD4^+/CD25^+$, $ CD3^+/CD49b^+$ cells increased significantly. In Paw joints, $CD3^+$, $ CD4^+$, $CD4^+/CD25^+$ cells decreased significantly. The level of serum IgG and IgM decreased significantly. The level of collagen II in the serum was decreased significantly. Marginal erosion, necrotic chodrocytes, cartilage and bone degradation were improved in histological section of paw joints. The results present significant immunological effect of GDGT on rats with arthritis induced by collgen II. So we expect that GDGT should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease.

Background: To assess the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of intraoperative gross examination (IGE) of uterine specimens in determining deep myometrial invasion and cervical invasion compared to final histology. Materials and Methods: The clinical, surgical and histological data of all FIGO stage I-II endometrial cancer (EC) patients who had primary surgery were reviewed. Results of the IGE for myometrial invasion and cervical invasion were compared to the final histology. The sensitivity, specificity, PPV, NPV, and accuracy of the IGE in determining deep myometrial invasion and cervical invasion were calculated. Association between clinico-pathological factors and discrepancy between IGE and final histology in the determination of myometrial invasion was also assessed. A p-value of <0.05 was considered significant. Results: From January 2007 to December 2012, 179 patients diagnosed with clinical stage I-II endometrial cancer underwent surgical staging. The sensitivity and specificity of IGE in detecting deep myometrial invasion were 42.4% and 90.0%, respectively, and the PPV and NPV were 67.6% and 76.1%. The overall accuracy of IGE was 74.3%. The sensitivity and specificity of IGE in identifying cervical invasion were 28.6% and 97.5%, respectively, while the PPV and NPV were 60.0% and 91.1%. The overall accuracy of IGE was 89.4%. Conclusions: The sensitivity of IGE for detecting deep myometrial invasion and cervical invasion in early-stage EC is too low to be used alone. Alternative methods including intraoperative frozen section analysis, preoperative three dimensional ultrasound, and preoperative magnetic resonance imaging should be strongly considered.

Background and Objective: Coptidis Rhizoma is a medicinal herb known for its antioxidant and anti-inflammatory effect. The purpose of this study was to examine the effects of CR on the experimental burn elicitation in vitro and in vivo. Material and Methods: In order to know the antioxidant effect on skin cell of mice after burn elicitation, superoxide dismutase (SOD) activity was measured. In vitro, the RAW 264.7 macrophage cells were treated with lipopolysaccharides for experimental inflammation. iNOS mRNA expression was observed after CR-treatment. In order to know effects on the skin regeneration in the burned mice, we counted the nitric oxide (NO) in blood. We also observed the histological structure in the epidermal basal layer and the dermal section, and we studied changes of angiogenesis in the capillaries surrounding the basal layer and dermal papilla. The changes of transcription of iNOS mRNA (inducible nitric oxide synthase mRNA) and changes of NF-${\kappa}$B (nuclear factor ${\kappa}$B) p65 positive reaction were also observed to investigate the changes of the stress in the skin. Results: The results indicated that CR has significant effects on the antioxidant effect on skin cells of mice after burn elicitation by increasing SOD activity in the in vitro test. It seemed that CR decreased the amount of NF-${\kappa}$B which induced the iNOS mRNA dose-dependently and suppress activating NO and angiogenesis. Furthermore, CR facilitated the process of skin recovery after experimental burn. Conclusion: CR can be applied for burned skin via antioxidant effect and skin regeneration.

We evaluated the hepatoprotective activity of crude hot-water extracts of the traditional Korean medicinal herb, Phellodendri Cortex (PC; Bark of Phellodendron amurense RUPR.), in an experimental model of hepatic damage induced by carbon tetrachloride ($CCl_4$). The serum marker of liver damage, sGOT, sGPT and sALP, were significantly decreased in the liver of the PC treated rats, compared with that of $CCl_4$ treated group. The histological observation of liver section of rats, showed the same protective effect of PC treatment. And the protective activity of PC was more significant in the post-treated group than pre-treated group. The significant decrease of malodialdehyde and increase of glutathion, catalase activity were observed in the liver homogenate of PC treated rats. Based on these findings, it is suggested that PC has potent hepatoprotective effects and the mechanism of the protection may be related to antioxidation pathways.

Objectives : The aim was to study the effect of bee venom pharmacopuncture therapy with different concentration on rheumatoid arthritis rat model. Methods : We enforced a bee venom pharmacopuncture therapy with different concentration on rheumatoid arthritis rat model by the intradermal injection of chicken type II collagen emulsified. 14 days after the onset of the rheumatoid arthritis rat model, a fixed volume of bee venom was daily injected to ST-35 acupoint in the rat's knee joint for 2-3 weeks. The hind paw volume, arthritic index, arthritic flexion pain test, pain threshold, and serum analysis (CRP, $PGE_2$, ALT, AST) were analyzed, and the expression profiles of COX-2, c-fos, and substance-P at the dorsal horn region of the spinal cord and subchondral bone of the knee joint were also analyzed by using the immunohistochemistry. Results : After the treatment of rheumatoid arthritis rats with bee venom pharmacopuncture, the paw volume of edema of arthritic rats were almost restored to the level of normal group, and behavior tests were very effective. Also the evaluation on the blood serum analysis was remarkable. COX-2, c-fos, and substance-P positive cells in the immunohistological section of dorsal horn region of the spinal cord and subchondral bone of the knee joints were significantly decreased. also the bee venom pharmacopuncture was effective to alleviate their rheumatoid arthritic inflammation cytokine inhibition as regards to the behavior tests and joint histological appearance. Conclusions : Based on the results in this study, bee venom pharmacopuncture with concentrated treatment condition was very effective in low fixed quantity and progressive low increased quantity.
