Through investigation on prescriptions from Dongeuibogam with Radix Puerariae as an ingredient, the following conclusions were reached. The 59 prescriptions with Radix Puerariae as an ingredient are mentioned from chapter of Pediatrics to chapter of Intestinal Convulsions. And 85% of those appears from chapter of Pediatrics to chapter of coughs. Prescriptions with Radix Puerariae as the main ingredient are used for skin diseases, cold, epidemics, abscess, diabetes, stroke, feverish diseases, intestinal diseases, weakness and cough. The dosage of Radix Puerariae varies from 0.875g to 11.25g. 3.75g was the most frequently used dosage which accounts 44%. And those with small dosage of 0.875 to 1.125g were for use on infants or pregnant women. The grounding pathology used for prescriptions with Radix Puerariae as an ingredient appeared to be mostly the pathology related to the Six External Qi. Among this, wind with cold(風寒), wind, cold with heat and humidity(風寒署濕), catching cold(傷寒), successively catching cold(兩感傷寒), cold of the Yangmyung and heat clogging(陽明傷寒火鬱), abnormal weather(時令不正) are the majority. Through the prescriptions with Radix Puerariae as an ingredient, it could be concluded Radix Puerariae that has various functions such as sweating and removing rash(發表透疹), exhalation and curing muscular ache(發散解肌), producing body fluid and ceasing thirst(生津止渴), opening abscess and healing the scar(托瘡生肌), removal of fever(解熱), resolving hangover(醒酒). Seungmagalguntang(升麻葛根湯) is used as the base prescription the most, and various prescriptions and herbs are combined according to the case.

The musculoskeletal system can be involved as an extra-intestinal manifestation of inflammatory bowel disease. Among these, myositis in ulcerative colitis (UC) is very rare. A 14-year-old girl was admitted due to severe shoulder tenderness. She had complained of left jaw pain and swelling for the past 10 days. Inflammatory markers were elevated with no evidence of infectious etiology. Myositis was suspected by shoulder magnetic resonance imaging. Three days after admission, she developed hematochezia. Muscle biopsy and colonoscopy was performed due to worsening left mandibular area pain and persistent hematochezia. Colonoscopy showed consistent findings with UC. She was finally diagnosed with UC with myositis as an extra-intestinal manifestation. She showed a dramatic response to UC treatment. Gastrointestinal symptoms were well-controlled. After 14 months, UC symptoms and muscle pain were aggravated, which were relieved after steroid and cyclosporin treatment. We report a unique case of UC initially presented with myositis, preceding gastrointestinal symptoms.

Electroacupuncture is the combined treatment of mechanical and electric stimuli on the needle head, on which electricity runs after acupuncturing at the acupuncture points. It is reported that its treatment effect depends on the parameter of stimulus, which is wave of stimulus, frequency, voltage, and duration of electric current. To get the effective treatment, stimulus intensity over threshold is needed. We planned to experiment whether acupuncture effect is affected by sex, age, and weight. After we conducted electric stimulus at Zusanli(ST 36) which is known to increase small intestinal motility in normal rats, we observed the effects and got the following results. Though the increased effects of small intestinal motility of electro-acupuncture at Zusanli(ST 36) did not show the difference of sex, this effect was observed to have a tendency to decrease according to weight increase without distinction of sex. But the effect of electro-acupuncture shown in 4, 5, 7 weeks old without distinction of sex was observed to have a tendency to decrease with the growing of weeks-old in the male rat group. And the significant change without specific tendency was observed in the 4, 5 weeks old female rat group. This result suggested that sex, weight, and age should be considered to get the efficient electro-acupuncture. The more experimental study should be advanced to investigate the correlation between the factors that can affect the acupuncture treatment, and, afterward, the interconnection into the clinical use.

Purpose: When cancer cels invade the stroma, they should be dissociated from the adjacent cells at first. E-cadherin and $\beta-catenin$ constitute an important protein complex associated with cellular adhesion, development, and differentiation, especially in epithelial cells. The role of E-cadherin and $\beta-catenin$ in gastric carcinogenesis were studied. Materials and Methods: The expression of E-cadherin and $\beta-catenin$ in gastric adenocarcinomas by using immunohistochemical staining and the mutation by using polymerase chain reaction- single stranded conformation polymorphism (PCR-SSCP) and sequencing were performed in 40 adenocarcinomas and 5 dysplasia of stomach. Thirteen cases, which had lymph node metastasis, were also included for immunohistochemical staining. Results: Inappropriate cytoplasmic and/or nuclear expression of a E-cadherin-$\beta-catenin$ complex was more frequent in poorly differentiated, diffuse type signet ring cell carcinomas than in well-differentiated, intestinal type adenocarcinomas (P<0.05). However, the expression was not related with clinical stage or lymph node metastasis. Mutation of E-cadherin was detected in 4 cases by using PCR-SSCP, whereas mutation of $\beta-catenin$ was detected in 2 cases. Conclusion: E-cadherin and $\beta-catenin$ seem to be important in gastric carcinogenesis, especially in poorly differentiated diffuse type.

Purpose: The p53 protein is a tumor supressor gene, and its mutation is associated with biologic aggressiveness. CD44v6, one of the CD44 family, is a cell surface glycoprotein that plays a role in cancer invasion and metastasis. Vascular endothelial growth factor (VEGF) is another recently identified growth factor with significant angiogenic properties. The purpose of this study was to investigate p53, CD44v6, and VEGF expressions to determine whether degree of expression was related to pathological parameters such as Lauren's classification, depth of invasion, and lymph node metastasis. Materials and Methods: Immunohistochemical stains of p53, CD44v6, and VEGF in formalin-fixed paraffin-embedded tissue sections of 125 gastric adenocarcinomas were done. Results: The overall expression rates of p53, CD44v6, and VEGF were $54.4\%$ (68/125), $36.8\%$ (46/125), and $48.0\%$ (60/125), respectively. The p53, not CD44v6 and VEGF was higher in intestinal-type gastric carcinomas by Lauren's classification. The expressions of p53, CD44v6, and VEGF were statistically correlated with depth of tumor invasion. The expression of CD44v6 was higher in the lymph node metastatic group than in the negative group. The p53 expression was significantly associated with VEGF expression. Conclusions: These data suggest that the expressions of p53, CD44v6, and VEGF are biologically related to malignancy. The p53 and CD44v6 expressions are independent; however, p53 gene mutation is one of the contributing factors to VEGF expression in gastric adenocarcinoma.

Both immunoelectron microscopy(IEM) and immunogold conjugate immunoelectron microscopy (IGC-IEM) techniques were developed for the detection of porcine epidemic diarrhea virus(PEDV) from the feces. Fecal samples were incubated sequentially with anti-PEDV monoclonal antibody(MoAb) and immunogold conjugated goat anti-mouse IgG+IgM. Then negatively stained, mounted on the formvar carbon-coated copper EM grids and observed by the transmission electron microscope. By the direct electron microscopy(DEM), coronavirus particles were observed from 17 cases of total 33 fecal samples of grower pigs and sows. The virons of coronavirus were moderately pleomorphic but mostly spherical, with a diameter ranged from 90 to 190nm. PED virus particles were identified from 15 cases of 17 DEM positive samples by the IEM and IGC-IEM techniques. Aggregates of PED virus coated with specific antibody were seen in fecal samples incubated with homologous anti-PED virus MoAb but not in control samples incubated with anti-TGE virus MoAb. Following incubation with immunogold-conjugated secondary antibody, the gold granules were usually distributed around and among the virus particles and soluble and viral particle-associated antigen. So, IEM and IGC-IEM techniques were proved a rapid and sensitive methods for detection and identification of PED virus from fecal and intestinal contents.

Nowadays, Klebsiella oxytoca is described as a causative organism for antibiotic-associated hemorrhagic colitis (AAHC). Here we report two cases of pediatric AAHC, from which K. oxytoca was cultured after starting amoxicillin-clavulanate or amoxicillin treatment. The patients developed severe abdominal pain and a large amount of bloody diarrhea. K. oxytoca was obtained in intestinal fluid culture of a boy through the colonoscopy. On the other hand, colonic tissue culture and intestinal fluid culture were negative of the other patient. K. oxytoca was detected in stool culture when he was admitted. These cases showed characteristic endoscopic findings of segmental hemorrhagic colitis, and both boys recovered spontaneously within 2-3 days after they stopped taking the antibiotics. Therefore, in children who develop relatively large amount of bloody diarrhea after antibiotic treatment, we should consider AAHC caused by K. oxytoca.

The animal gut is filled with highly diverse microbes associated with host metabolism, physiology, and pathology. However, numerous animal gut microbes have not been cultured or reported. We isolated various bacterial species using culture-dependent approaches during a comprehensive investigation of endangered endemic vertebrate species in the Republic of Korea. A total of 18 unrecorded bacterial species were isolated from the feces of an Oriental stork (Ciconia boyciana), and from the intestinal tracts of a cobitid fish (Kichulchoia multifasciata) and a Korean splendid dace (Coreoleuciscus splendidus). Based on a phylogenetic analysis of 16S rRNA gene sequences, we discovered species belonging to the phyla Actinobacteria (eight species), Firmicutes (seven species), Proteobacteria (two species), and Bacteroidetes (one species). Based on their high 16S rRNA gene sequence similarities (>98.7%) and formation of monophyletic clades with type species, each species was classified into an independent and predefined bacterial species. Gram-stain reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and NIBR IDs for each species are described in the species description section.
