Objectives The purpose of this study is to understand the correlations between lung, large intestine, and skin of 3-week-old mice in which ulcerative colitis was induced, up on administration of Coptidis rhizome and Glycyrrhiza uralensis mixed extract. Methods Mice were divided into 4 groups as follows; no treatment group (Ctrl group), ulcerative colitis-induced mice group (UE group), ulcerative colitis-induced mice group after administering Pentasa (PT group), ulcerative colitis-induced mice group after administering Coptidis rhizoma and Glycyrrhiza uralensis mixed extract (CGT group). Mice were induced ulcerative colitis by Dextran sulfate sodium (DSS). After 5 days of administration, We obvserved anti-inflammatory effect, alveolar formation, and skin barrier control in the colon mucosa. Results The CGT group was observed arrangement of normal intestinal cells, Infiltration of less inflammatory cells. The CGT significantly decreased positive rseponse of $TNF-{\alpha}$, p-IkB, Caspase 3 in large intestine, and significantly increased positive rseponse of EGF, IGF, catalase, Filaggrin, involucrin, loricrin. Conclusions The results of this study show the correlation of Lung-Large intestine-Skin by administering Coptidis rhizoma and Glycyrrhiza uralensis mixed extract to ulcerative colitis-induced mice.

A gene encoding a novel geranylgeranyl pyrophosphate (GGPP) synthase from Kocuria gwangalliensis has been cloned and expressed in Escherichia coli. The deduced amino acid sequence showed 59.6% identity with a putative GGPP synthase (CrtE) from K. rhizophila. An expression plasmid containing the crtE gene was constructed, and E. coli cells containing this plasmid produced a recombinant protein with a theoretical molecular mass of 41 kDa, corresponding to the molecular weight of GGPP synthase. Due to the lack of crtE, crtB, and crtI in E. coli, the biosynthesis of lycopene was only obtained when the plasmid pCcrtE was co-transformed into E. coli expressing the pRScrtBI-carrying carotenoid biosynthesis crtB and crtI genes, which were sub-cloned from Paracoccus haeundaensis. The biochemical studies on the expressed proteins were performed via HPLC. The results obtained from this study will provide a wider base of knowledge regarding the primary structure of CrtE cloned from K. gwangalliensis at the molecular level.

Purpose: Lymphonodular hyperplasia of the colon (LNHC) is a rare finding in children and its significance as a pathologic finding is unclear. The aim of this study was to investigate the clinical significance of LNHC by analyzing clinical and histopathologic findings in children with LNHC. Methods: We analyzed data from 38 patients who were confirmed to have LNHC by colonoscopy. We checked age, birth history, past history, family history, and clinical symptoms. A hematologic exam, stool exam, and image studies were performed and biopsy specimens were examined by a pathologist. All patients were asked to have short- and long-term follow-up. Results: The mean age of the patients was 12.5${\pm}$14.4 months. All patients presented with complaints of bloody stool. They appeared healthy and the hematologic findings were within a normal range, with the exception of one case. There was no other identified source of bleeding. On histologic exam, 36 patients (94.7%) had lymphoid follicles and 34 patients (84.5%) fulfilled the criteria of allergic colitis. Regardless of diet modification and presence of residual symptom, there was no recurrence of bloody stool through long-term follow-up in all patients. Conclusion: LNHC is more common in infants who are affected by allergic colitis, but it can appear even after infancy. LNHC should be regarded as the etiology when there are any other causes of rectal bleeding, especially in healthy children. We suggest that LNHC has a benign course regardless of diet modification and it might not require excessive concerns.

The drinking water in the apartment is stored in reservior tank and thereafter supplied each household. In case the drinking water is stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physico-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows : PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the appartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number(MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriated in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chlorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.

The nar promoter of Escherichta coli, which is maximally induced under anaerobic conditions in the presence of nitrate, was characterized to see whether the nar promoter cloned onto pBR322 can be used as an expression promoter. The modified nar promoter, in which several bases in the -10 region was mutated to the consensus sequence by site-directed mutagenesis, was characterized in E. coli, on which chromosome the fnr gene affecting expression of the nar promoter according to dissolved oxygen level was mutated. The E. coli lacZ gene was used as a reporter gene. The following effects were investigated to find optimal conditions to induce the modified nar promoter: induction methods, optimal nitrate concentrations, the amount of ${\beta}$-galactosidase expressed at the different growth conditions, and induction characteristics. The following results were obtained from the experiments : expression of ${\beta}$-galactosidase from the modified nar promoter was not affected much by nitrate concentrations. The maximal specific ${\beta}$-galactosidase activity was obtained when E. coli was grown under aerobic conditions, and then the modified nar promoter was induced at OD600=2.2 under microaerobic conditions (DO=1∼2%), under which conditions the maximal specific ${\beta}$-galactosidase activity was 13,000 Miller units. However, the specific ${\beta}$-galactosidase activity was approximately 6,000 Miller units even before the modified nar promoter was induced. Therefore, the modified nar promoter seemed to be useful when the cloned gene wants to be expressed in E. coli constitutively.

E. tarda, a fish pathogen, can survive in seawater under relatively high salt conditions as well as in fish under physiological salt conditions. Bacterial growth under different salt concentrations may influence the expression of genes involved in bacterial structure and physiology. The growth rate of E. tarda culture in high salt (3.5% NaCl) was similar to that in low salt (1.0% NaCl, physiological salt concentration). Interestingly, the strain moved much faster in low salt conditions than in high salt conditions. Electron microscopic observation demonstrated that the bacterial cells grown in high salt had less or no flagellation. Obvious flagellation was observed in the parental strain E. tarda CK41 grown in low-salt condition. Two putative genes coding flagellin were identified in the E. tarda genome sequences. The amino acid sequence comparison of each gene revealed 93% identities. A flagellin gene was PCR amplified and cloned into a cloning vector. Using an E. coli protein expression system, a part of flagellin protein was overexpressed. Using the purified protein, an anti-flagellin antibody was raised in the rabbit. Immunoblot analyses with flagellin specific antibody demonstrated that E. tarda CK41 expressed falgellin in low salt conditions, which is consistent with the results seen in motility assay and microscopic observation. This is the first report of salt regulated flagella expression in E. tarda.

Microbiological characteristics of low salt Mul-kimchi was examined. Mul-kimchi was prepared by mixing of radish (25%), green onion (2.4%), red pepper (1.9%), garlic (1.9%) and salt (0, 0.2, 0.5, 1.0, 1.5, 2.0, 2.5, 2.5, 3.0%) in water and fermented at 4, 15 and $25^{\circ}C$ for 10 days, respectively. During fermentation period, total cell, Leuconostoc sp., Lactobacillus sp., Streptococcus sp., Pediococcus sp., coliform bacteria, gram (-) bacteria and yeast cell number were counted on their selection media. The microbes in Mul-kimchi were isolated and identified. Total cell number increased as salt concentration decreased and fermentation temperature increased. Lactic acid bacteria showed the highest number in 1.0% salt concentration. Yeast cell number increased with increase of salt concentration. Lactobacillus sp. were identified Lactobacillus plantarum and L. pentosus in Mul-kimchi containing $0.2{\sim}1.0%$ salt while those of Mul-kimchi containing 3.0% salt were Lactobacillus plantarum and L. brevis. The other lactic acid bacteria were identified Leuconostoc citrum, Leu.mes.ssp.mesenteroides/dextranicum and streptococcus facium in Mul-kimchi containing $0{\sim}3.0%$ salt while Pediococcus sp. was not detected. Gram-negative Aeromonas hydrophila, Pseudomonas fluorescens, Pseu. aureofaciens and yeast Candida pelliculosa, Cryptococcus laurentii were identified in the Mul-kimchi.
