  • As the preservation law of soil environment has reinforced, several soil remediation projects have been performing for railroad sites. One of the main sources of soil contamination is the leakage of diesel from locomotives or underground storage tank. Also, the lubricant used to maintain turnouts causes railroad soil contamination. The purpose of this study was to develop the analysis and the remediation method for lubricant-contaminated soil. The lubricant in the contaminated soil was analyzed qualitatively and quantitatively by TLC (Thin Layer Chromatography) and GC (Gas Chromatography), respectively. The organic pollutants were removed from the soil using microorganisms degrading lubricant. Hereafter it will be necessary to apply this bioremediation method in the railroad field.

  • Nonsteriodal antiinflammatory drugs(NSAIDs) are widely used to treat pain. fever, and inflammatory conditions including osteoarthritis. However, gastrointestinal (GI) and renal toxicity were related to common NSAIDs limits their usefulness because NSAIDs inhibit not only COX-2 associated with anti-inflammatory activity. but also COX-1 accompanied with side effects in the stomach and kidney.
