The resistant strains due to the extended-spectrum $\beta$-lactamase (ESBL) were susceptible to cefatrizine combined with clavulanic acid. The purpose of this study was to evaluate the in vitro and in vivo antibacterial activities of cefatrizine/clavulanic acid (CTRZ/CV) combination at a ratio of 2 : 1 in comparison with cefaclor (CCLO), cefuroxime (CRXM), cefuroxime axetil (CRXMA) and amoxicillin/clavulanic acid (AMXCCV). CTRZ/CV showed good activity against laboratory strains of gram-positive and gram-negative bacteria and exhibited excellent antibacterial activity against $\beta$-lactamase-producing strains. The bactericidal activity of CTRZ/CV was superior to that of CCLO and CRXM, and almost equal to that of AMXCCV against the $\beta$-lactamase-producing strains. The in vitro results were substantiated. by in vivo mouse experimental infection studies with $\beta$-lactamase-producing and non-producing strains. In mixed experimental infection due to $\beta$-lactamase-producing and non-producing strains, the therapeutic efficacy of CTRZ/CV was superior to that of CTRZ, CCLO, CRXMA and AMXCCV. In respiratory tract infection in mice due to Klebsiella pneumoniae EB4O, CTRZ/CV was more erective than CCLO, CRXMA and AMXCCV and also more efficacious than CCLO, CRXMA and AMXCCV in urinary tract infection in mice due to Escherichia coli EB13. These results indicate that CTRZ/CV is a useful drug for the treatment of infection caused by $\beta$-1actamase-producing strains including ESBL-producing strains.

The results of the measurement of the flow-rate coefficient (Cv-value) and the analysis of a small ball valve are summarized follows. The Cv-values of 1/2-, 3/4- and 1-inch ball valves were measured using a flow-rate measurement test. The manufacturer obtained the Cv-value using a theoretical calculation method. The new experimental measurement and analysis method yielded more reliable results. In addition, the Cv value obtained through numerical analysis was almost identical the value provided by the manufacturer, which was based on experimental results. A Study on Flow Analysis results are all similar appearances as the reliability of the results.

The optimal condition for Morus alba cv was an MS culture medium at $27^{\circ}C$ for 20 days. Cheongmoknosang callus showed inhibitory activity against Helicobacter pylori at 1.05 g of wet weight of the cultured callus. The callus formation of Morus alba cv. Cheongmoknosang was influenced by naphthalene acetic acid (NAA), 2,4-dichlorophenoxy acetic acid (2,4-D), 6-benzylaminopurine (BA) and kinetin at concentrations of 2 mg/l. The growth rate of callus was higher than it was when these hormones were mixed with a single hormone. Thus, the optimal condition for direct callogenesis was to incubate with mixture (2,4-D/NAA) of 2 mg/l concentration at $27^{\circ}C$ for 20 days. Moreover, the optimal culture condition of the biomass in the mass production of inhibitory compounds against Helicobacter pylori from Morus alba cv. Cheongmoknosang callus was to incubate in an MS broth (each concentration 1 mg/l of 2,4-D and BA). When Morus alba cv. Cheongmoknosang callus were incubated for 20 days in a bioreactor, Helicobacter pylori inhibition of callus extracts was the highest at a clear zone of 16 mm.

Background: Elderly patients with gastrointestinal (GI) and cardiovascular (CV) risk factors may be more easily exposed to NSAID-related side effects (SEs). Based on the ACG guideline of year 2009, the aim of the study is to evaluate proper use of NSAIDs and gastroprotective drugs according to the degree of GI and CV risk strengths in the patients. Methods: Retrospectively surveyed 410 elderly patients with NSAIDs for more than 30 days at a general hospital in Korea. GI risk factor includes age, ulcer history, high-dose NSIADs, concurrent aspirin use, steroids or anticoagulants. CV risk factor includes angina, myocardial infarction, cerebral infarction, atrial fibrillation or coronary intervention requiring low-dose aspirin. These factors were classified as high/low cardiovascular groups and high/moderate/low GI groups. Results: There were 14 patients in high CV risk group and high GI risk group. The group was recommended not to use NSAIDs as it is not adequate. There were 101 patients in high CV risk group and moderate GI risk group. This group was recommended to use naproxen and PPI/misoprostol. But all patients except one were not adequate. There were 9 patients in low CV risk group and high GI risk group. This group was recommended to use selective COX-2 inhibitor and PPI/misoprostol. 5 cases were proper while 4 cases did not. There were 285 patients in low CV risk and moderate GI risk group who were recommended to use non selective NSAIDs and PPI/misoprostol or selective COX-2 inhibitor only. 103 patients were proper while 182 patients not adequate. Overall, the SEs were higher in those cases for inadequate use of drugs comparing to the adequate. CV SEs were statistically significant. However, SEs for each risk groups were different. For the case of low CV risk group and high/moderate GI risk group, the inadequate use of drugs makes the SE high and the other groups are not. Also, it was not statistically significant. Conclusions: In elderly patients, the inappropriate use of NSAIDs can increase the risk of the disease. Therefore, GI and CV risk must be considered simultaneously, and the proper use of NSAIDs and gastroprotective drugs for each risk groups should be reconsidered.

The usefulness of totally implantable central venous port for long-term intravenous infusion is widely accepted in children. Usually the catheters are placed through the internal or external jugular vein. In case of jugular vein cut-down, two separate incisions are needed for catheter and port respectively. Patients also feel uncomfortable as the catheter run through the neck. However these disadvantages can be overcome by using the cephalic vein (CV). We reviewed our experiences on CV cut-down for totally implantable central venous port in children. From January 2002 to December 2006, 201 patients (M:F=127:74) underwent 218 central venous port insertions. Mean age at operation was 5.9 years (2 months - 19 years). Indications included chemotherapy (N=167), long-term intravenous antibiotics infusion (N=36), and total parenteral nutrition (N=15). CV was selected preferentially. The incision includes the deltopectoral triangle laterally, and both the CV cut-down and port insertion were achieved with a single incision. The number of insertion through external, internal jugular vein, and CV was 77, 66 and 75, respectively. The median age, height and body weight were higher in CV cut-down group. The youngest age for CV cut-down was 8 months, the shortest height was 69 cm and the smallest body weight was 5.9 kg. Of 118 trials of CV cut-down, cut-down was successful in 75 cases (63.6 %). CV was absent in 10 cases(8.4 %) and CV was sacrificed after catheter tip malposition in 10 cases (8.4 %). There was only one complication, in which the catheter was inserted into the minute branch of subclavian artery. The CV cut-down method for totally implantable central venous port was safe and feasible in selected groups of patients in children. In addition, preservation of jugular vein and a more favorable cosmetic effect are other benefits of CV cut-down.

The effect of various packaging methods on Kimchi quality was investigated in order to develop the packaging techniques for preventing commercial Kimchi Products from ination and explosion due to fermentative gas evolved during storage and distribution. Kimchi was packaged in different methods; atmospheric (AP), check-valved (CV), double (DP) and vacuum (VP) packaging. The quality of Kimchi during storage at $10^{\circ}C$ was evaluated ill terms of gas composition, free volume, pH, titratable acidity, color index, lactic acid bacteria and sensory properties. $O_2$ concentration decreased to about 1% at $6{\sim}8$ days of optimal ripening time in all packages except DP, in which it remained around 20%. $CO_2$ concentration reached $70{\sim}90%$ after $6{\sim}8$ days in AP, CV and DP, while it stayed around 10% in DP. The free volume in AP had typical sigmoidal curve similar to $CO_2$ concentration changes. It remained almost constant in CV and DP, but started to increase at the late stage of storage In VP. There was no significant influence of packaging methods on the other quality attributes such as pH, titratable acidity, color index (L.b/a), lactic acid bacteria count and sensory evaluation score. As results, it could be proposed to employ CV and DP method as the effective packaging techniques for preventing commercial Kimchi products from inflation.

Correction factors based on the catch ratios of egg and larval densities in the southern waters of Korea were estimated for anchovy Engraulis japonica. This was undertaken in order to adjust ichthyoplankton data from different sampling methods, gear types and time. Samples were collected during ichthyop1ankton surveys in Korean waters from 1983 to 1994. The ratios for egg densities obtained in vertical tows with a NORPAC net (ring $\Phi$, 45 cm) compared to those obtained in oblique tows with a KOB net (ring $\Phi$, 80 cm) were 0.86 (CV = 0.65), 1.22 (CV = 0.36), and 0.93 (CV = 0.42) for early, middle, and later developmental stages, respectively. The ratios for larval densities for vertical and oblique tows varied depending on size. For yolk-sac and small larvae (< 4 mm), the ratios were 3.08 (CV = 0.45) and 1.98 (CV = 1.34), while those of 4-6 mm, 6-8 mm, and 8-10 mm larvae were 0.44 (CV = 1.31), 0.45 (CV = 1.70), and 0.56 (CV = 2.50), respectively. Ratios of day/night densities for larvae of 4-10 mm lengths were lower (0.01-0.06) in offshore catches than values obtained in coastal areas (0.440.46) and similar values (0.16-0.04) for vertical and oblique tows. Our results indicated that vertical towing is more efficient for sampling early life stages (from eggs to larvae less than 4 mm long), while oblique towing is more efficient for larvae longer than 4 mm due to depth preferences for each developmental stage (e.g., changes in egg buoyancy and vertical migration oflarvae).
