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.

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.

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.

The applicability of a small hydro-power system for water pollution treatment facilities is investigated at the fish farm in Nam Jeju. For this study, the present situations of the fish farm are examined, and the running problem of screen is found out. As a means of solving this, the small hydro-power system which runs with seawater of head tank is considered. In order to apply this system, the field examination is carried out by sampling methods. The flux and the gross head are measured from selected site at the fish farm, and available generating electric power is estimated by these data. From this result, it is turned out that there is a set up possibility of this system at the fish farm.

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.

The main goals of the study were to investigate the sediment quality and trace metal distribution in sediment of Kwangyang Bay, south coastal of Korea. Surface sediment sampling were performed in November, 2000 and February and March, 2001. The concentration of H₂S, IL and COD in sediment were measured by a manual of the Department of Marine Environment of Korea. The extracted trace metals Fe, Cu, Cd, Pb, and Zn in sediments mean analyzed by the flame atomic absorption spectrophotometer with an instrument of model Shimadzu AA-6701F. H₂S, IL and COD in the surface sediment were 1.3 mg/g, 5.9 % and 15.0 mg/g, respectively. The mean content of Fe, Cu, Cd, Pb and Zn were 1523 mg/kg, 4.799 mg/kg, 1.321 mg/kg 9.285 mg/kg and 9.353 mg/kg, respectively. All of these measured trace metals level were over the other reported trace metal level in sediment of coastal area. According to histograms, the content of H₂S, IL and COD and trace metals in sediment of this study were affected by artificial activities rather than natural process.

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%.
