  • Anti-proliferation effects of Corni fructus ethanol extracts were investigated in the RC58T/h/SA#4 cells treated with environmental hormones including dioxin and bisphenol A. The proliferation was decreased at the concentration over $500{\mu}g/mL$ in the RC58T/h/SA#4 cells with ethanol extracts of various concentrations (1, 10, 100, 500, and $1000{\mu}g/mL$). The environmental hormones such as dioxin and bisphenol A increased the growth of RC58T/h/SA#4 cells in the charcoal-treated FBS (cFBS) medium. The proliferation was the highest at 1 nM and $0.1{\mu}M$ for the tested dioxin and bisphenol A concentration, respectively. Ethanol extracts showed inhibition of the proliferation in a dose-dependent manner at the tested concentrations (10, 100, 300, and $500{\mu}g/mL$) in the RC58T/h/SA#4 cells treated with the environmental hormones. The anti-proliferation was the highest at $500{\mu}g/mL$ concentration among the tested ethanol extracts.

  • 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is one of the best characterized environmental pollutants and is capable of causing a wide variety of toxicities including teratogenesis. TCDD has been known to increase as well as to decrease proliferation rates depending on the experimental conditions.(omitted)

  • 1977년 네덜란드에서 배출가스 및 집진재에서 다이옥신류를 검출해낸 이후 다이옥신 문제는 현재까지 전 세계적으로 중요한 환경문제로 인식되어 많은 연구가 진행되고 있다 우리나라에서도 '96년 국립환경연구원의 몇몇 쓰레기소각장 배출가스 중 다이옥신농도 발표 및 '97년 6월 환경부의 전국 소각장 다이옥신 배출실태조사결과가 발표되면서 시급히 해결해야 할 중요한 환경문제의 하나로 국민적 관심을 끌기 시작하였다. (중략)

  • The treatment of city life wastes is headache problem. Now, only small portion of burnable wastes is burnt at modern process incinerators, the other large portion is buried in the soil by landfill method. The burnable wastes will be increased year by year. The dioxin, the cancer-causing agent, produced by incineration of wastes influences harmful effect to national human health. The new idea of burnable wastes treatment is using the city life wastes as auxiliary fuel of fluidizing bed combustion boiler of large scale coal-fired power plant. The dioxin-free treatment of burnable wastes is sucessfully achieved by burning the wastes, in flyash storm at fluidizing bed combustion boiler.
