The purpose of this study was evaluate immunohistochemical observation to epidermal growth factor of the effect of duct ligation of mouse submandibular gland. Fifty two mice were aging 3 months old, devided into experimental group(36 mice) and control group (16 mice). Under general anesthesia, 36 animals were ligated in left side duct of submandibular gland. Experimental animals were sacrificed consecutively on 1st, 6th, 12th hours and 1st, 2nd, 3rd, 5th, 7th, 14th day after duct ligation. These specimens fixed with formalin and sectioned in paraffin. Subsequently were stained with H-E and immunohistochemistry to observe epidermal growth factor. The results were as follows ; 1. After duct ligation, the acinar cells were atrophied and disappeared and granular convoluted tubule cells in which cytoplasm atrophied and granules reduced, degenerated duct-like structure. 2. With the time lapse, epidermal growth factor in cytoplasm of granular convoluted tubule cells reduced with change of features of granular convoluted tubule. 3. From 7th day after duct ligation, there are suggested that duct-like structure were originated from granular convoluted tubule and these were regressive changes by secretory disturbance.

This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

Chung, Yang-Guk,Ha, Kee-Yong 가톨릭대학교 2000 Bulletin of The Catholic Research Institutes of Me Vol.28 No.-

Study Design : Bacterial adherence and biofilm formation in implant associated infection may depend on species of microorganism, types of strains. the physical or chemical characteristics of the implant surfaces. Objectives : To evaluate the differences of adherence and biofilm formation between S. epdermidis and M. tuberculosis on smooth surfaced or rough surfaced stainless steel and titanium alloy, respectively. Summary of Literature Review : In implant associated infections, bacteria in biofilm are resistant to antibiotics or host defence mechanism and removal of implants is usually necessary to eradecate infection. On contrary, spinal instrumentation with complete debridement and antituberculosis chemotherapy is a safe procedure for spinal tuberculosis. Mterials and Methods : S. epdermidis and M. tuberculosis were cultured with 4 types of rod segments which consisted of smooth and rough surfaced stainless steel and titanium alloy, respectively. After isolation with trypsin treatment and culture on plate media, colony forming units(CFUs) were counted. The feature of adherence and biofilm formation were observed under scanning electron microscopy (SEM). Result : Biofilm forming S. epdermidis showed heavy adhesion and multiplication on surface of all 4 rod segments, 16.5 times more CFUs than biofilm non-forming ones, especially on smooth surfaced stainless steel. On SEM field, there were many aggregated micro-colonies with thick amorphous biofilm in biofilm forming S. epidermidis and much less in biofilm non-forming S. epdermidis, M. tuberculosis rarely adhered to metal surfaces. On SEM, there were few tubercle bacilli and scanty biofilm formation. Conclusions : Biofilm may play an important role in adhesion and multiplication of S. epdermidis butr adherence and biofilm formation of M. tuberculosis on implant surface are less likely and it can provide the basis of instrumentation in spinal tuberculosis.

Two pathways of ammonium assimilation and glutamate biosynthesis have been identified in microorganisms. One pathway involves the NADP-linked glutamate dehydrogenase, which catalyzes the amination of 2-oxoglutarate to form glutamate. An alternative pathway involves the combined activities of glutamine synthetase, which aminates glutamate to form glutamine, and glutamate synthase, which transfers the amide group of glutamine to 2-oxoglutarate to yield two molecules of glutamate. We have cloned the large subunit of the glutamate synthase (GOGAT) from Salmonella typhimurium by screening the expression of GOGAT and complementing the gene in E. coli GOGAT large subunit-deficient mutants. Three positive clones (named pUC19C12, pUC19C13 and pUC19C15) contained identical Sau3AI fragments, as determined by restriction mapping and Southern hybridization, and expressed GOGAT efficiently and constitutively using its own promoter in the heterologous host. The coding region expressed in Escherichia coli was about 170 kDa on SDS-PAGE. This gene spans 4,732 bases, contains an open reading frame of 4,458 nucleotides, and encodes a mature protein of 1,486 amino acid residues (Mr =166,208). The EMN-binding domain of GOGAT contains 12 glycine residues, and the 3Fe-4S cluster has 3 cysteine residues. The comparison of the translated amino acid sequence of the Salmonella GOGAT with sequences from other bacteria such as Escherichia coli, Salmonella enterica, Shigella flexneri, Yersinia pestis, Vibrio vulnificus and Pseudomonas aeruginosa shows sequence identity between 87 and 95%.
