A microarray study has been employed to understand changes of gene expression in E. coli KD43162 resistant to ampicillin, ampicillin-sulbactam, piperacillin, piperacillin-tazobactam, cefazolin, cefepime, aztreonam, imipenem, meropenem, gentamicin, tobramycin, ciprofloxacin, levofloxacin, moxifloxacin, fosfomycin, and trimethoprim-sulfamethoxazole except for amikacin using disk diffusion assay. Using Sodium dodecyl sulphate-polyacrylamide gel electrophoresis and MALDI-TOF MS analyses, 36 kDa of outer membrane proteins (OMPs) was found to be deleted in the multidrug resistant E. coli KD 43162. Microarray analysis was used to determine up- and down-regulated genes in relation to multidrug resistant E. coli KD43162. Among the up-regulated genes, these genes were corresponded to express the proteins as penicillin-binding proteins (PBPs), tartronate semialdehyde reductase, ethanolamine utilization protein, shikimate kinase I, allantoinase, predicted SAM-dependent methyltransferase, L-glutamine: D-fructose-6-phosphate aminotransferase (GFAT), phospho-glucosamine mutase, predicted N-acetylmannosamine kinase, and predicted N-acetylmannosamine-6-P epimerase. Up-regulation of PBPs, one of primary target sites of antibiotics, might be responsible for the multidrug resistance in E. coli with increasing amount of target sites. Up-regulation of GFAT enzyme may be related to the up-regulation of PBPs because GFAT produces N-acetylglucosamine, a precursor of peptidoglycans. One of GFAT inhibitors, azaserine, showed a potent inhibition on the growth of E. coli KD43162. In conclusion, up-regulation of PBPs and GFATs with the loss of 36 kDa OMP refers the multidrug resistance in E. coli KD 43162.

Dental caries is a chronic disease that causes the destruction of tooth structure by the interaction of plaque bacteria, food debris, and saliva. There has been attempts to induce remineralization by supersaturating the Intra-oral environment around the surface enamel, where there is incipient caries. In this study, supersaturated remineralized solution "R" was applied to specimens with incipient enamel caries, and the quantitative analysis of remineralization was evaluated using microradiography. Thirty subjects volunteered to participate in this study. Removable appliances were constructed for the subjects, and the enamel specimen with incipient caries were embedded in the appliances. The subjects wore the intra-oral appliance for 15 days except while eating and sleeping. The removable appliance were soaked in supersaturated solution "R", saline, or Senstime$^{\circledR}$ to expose the specimen to those solutions three times a day, 5 minutes each time. After 15 days, microradiography was retaken to compare and evaluate remineralization The results were as the following: 1. The ratio of remineralized area to demineralized area was significantly higher in the supersaturated solution "R" and Senstime$^{\circledR}$ than in the saline (p<0.05) 2. Remineralization in the supersaturated buffer solution "R" occurred in the significantly deeper parts of the tooth. compared to the Senstime$^{\circledR}$ group containing high concentration or fluoride. (p<0.05) As in the above results, the remineralization effect of remineralized buffer solution "R" on incipient enamel caries has been proven. For clinical utilization, further studies on soft tissue reaction and the effect on dentin and cementum are necessary In conclusion compared to commercially available fluoride solution. remineralization solution“R”showed better remineralization effect on early enamel caries lesion, so it is considered as effecient solution for clinical application.

Advances in medical procedures and utilization of medication have resulted in expanding aged population, which leads to increased aged patients with salivary hypofunction and its associated symptoms in dental clinic. The purpose of this study was to investigate clinical characteristics of patients with dry mouth and its correlation with their salivary flow rate. Forty dry mouth patients (7 males, 33 females, mean age 42.0 years) whose flow rate of unstimulated whole saliva was less than 0.15 ml/min were included and their gender- and age-matched controls (7 males, 33 females, mean age 42.9 years) who did not report any complaints, suggestive of salivary gland dysfunction and had the flow rate of greater than 0.20 ml/min were included for comparison. The salivary flow rate was measured in both unstimulated and stimulated conditions. Dry mouth-related clinical information including history, dry mouth associated symptoms, exacerbating and relieving factors, drugs, systemic diseases, and family history was investigated using questionnaires. The differences in distribution of patients and control subjects to each question and their relation to the salivary flow rate were analyzed and we came to following conclusions. 1. There were statistically significant differences in the distribution of patients and controls to the following questions: the period and frequency of suffering from dry mouth; severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods, severity of discomfort in usual life due to dry feeling; self-assessment of residual salivary volume; taking medications. 2. The patients had more stress-related medical histories including indigestion, insomnia, and gastritis compared with controls. The patients took many kinds of medications to control their systemic diseases. 3. There were statistically significant differences in the salivary flow rate between different groups of patients to following questions: severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one. 4. The salivary flow rate of patients taking medications was significantly less than that of patients who did not take medications. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one.
