This experiment investigated changes in metabolic rate (MO2), critical oxygen saturation (Scrit), and blood chemistry of olive flounder Paralichthys olivaceus exposed to progressive hypoxia and returned to normoxic water at 20°C. The normoxic standard metabolic rate (SMR) and routine metabolic rate (RMR) were 69.5-83.9 and 70.2-156.4 mg O2 kg-1h-1, respectively based on fish weight. Scrit was 31.0% dissolved oxygen (DO) at 20°C. After returning the fish to 70% DO following exposure to hypoxia (20% DO), MO2 increased two-fold compared to the normoxic SMR and then decreased into the range of the RMR with time. Blood PO2 and plasma lactate decreased significantly after exposure to hypoxia (20% DO) and then increased as ambient oxygen saturation decreased. Cortisol levels increased as ambient oxygen saturation decreased, but the levels decreased rapidly in the range of the normoxic control when the fish were returned to ambient water with 70% DO. Plasma glucose levels increased when the fish were returned to normoxic water after exposure to a progressively more hypoxic condition.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

We studied the oxidation of docosahexaenoic acid(DHA: C22: 6ω-3). β-Cyclodextrin(CD) inclusion complexes(ICs) of DHA were prepared with antioxidant such as α-tocopherol and BHT, and microcapsulated with Curdlan and Pullulan. Identification of their structural features of ICs were observed with the use of SEM, FTR, and XRD. Methods for quantitative analysis of DHA were used: TLC scanning method and TBARS(Thiobarbituric acid reactive substance) method. As a result, we observed the formation of ICs and estimated antioxidant effect. In this work, loading efficiency of DHA in ICs was about 25%, and the antioxidant effect of α-tocopherol was higher than that of BHT. When ICs containing DHA was microcapsulated with curdlan and pullulan, the loading efficiency was less than 5%.

Numerous evidences support the pathogenesis that M. pneumonias pneumonia is associated with cell-mediat-ed immune reaction. We report 2 cases of severe M. pneumoniae pneumonia in previously healthy sisters, who were both admitted during an epidemic of M. pneumoniae pneumonia. The elder sister, who was 16 years old, was admitted with M. pneumoniae pneumonia. She showed no response to treatment with clarithroycin and levo-floxacin, and eventually progressed to severe ARDS, requiring mechanical ventilation. After treatment with hydrocortisone (200 mg/day), there were rapid improvements in clinical manifestations and chest radiographic findings. The younger sister, who was 14 years old, was admitted 10 days later, Presenting with fever but no pneumonic lesions on chest radiograph. Just like her sister, the infection showed no response to clarithromycin. Fever persisted and pneumonic consolidation with mild pleural effusion was noticed in the left lower lobe on the 5th hospital-day. After treatment with oral prednisolone (1 mg/kg), she showed rapid defervescence and on the 8th hospital day, no pneumonic lesions were detectable on chest radiograph. Given the fact that the pathogenesis of pneumonia and extrapulmonary manifestations in M. pneumoniae infection is immune-mediated, an immuno-suppressive therapy would be validated for selected patients with M. pneumoniae infections.

Pneumatic cushion cylinders are most widely used as actuators in automatic equipment because they are relatively inexpensive, simple to install and maintain, offer robust design and operation, are available in a wide range of standard sizes and design alternatives. Compressed air is a very expensive form of energy and therefore systems have been proposed to conserve pneumatic energy which mostly means lowering the supply pressure. The purpose of this paper is to compare meter-out and meter-in speed control of high speed pneumatic cushion cylinder. A mathematical simulation model of a double acting pneumatic cushion cylinder used the relief valve type is presented. The dynamic characteristics in the horizontally-mounted pneumatic cylinder, the meter-out and meter-in speed control are investigated with variation of the supply pressure, total mass, effective area of flow control valve, cracking pressure of relief valve, piston rod diameter, stroke, cushion sleeve length etc.

This study analyzed current issues by theoretical investigation on and by the research of current situation and actual condition on all the matters for public relation of Judo. I suggested the importance of internet, a method for future public relation, researched methods for its utilization and system for making up contents and approached internet to the public relation of judo. The strategies for the public relation of judo are as below. First, it should consist of better rich contents ill order for people to know the records of judo match current conditions on its players, public relation of the matches, etc.. Also, the chiefs of private judo halls should have interests in the public relation through internet and make assurance doubly sure of public relation of private judo halls since it is thought that all the people can easily approach it no matter what their majors are considering that today the number of people using internet are increasing in geometric progression and internet maintains lots of consumers regardless of social classes owing to rapidly spreading internet pervasion, technology development of various multi media and commercialization of information. Second, internet can quickly and exactly transmit accurate information needed for the target group with cheap price and with no limits of time and space though almost all methods such as telephone line, cable television, earth satellite, wireless communication information expressway, etc. and thus can obtain feedback for the simple and convenient addition of new technology or revised regulations to the existing data.
