  • The oral administration of extracts of young radishes cultivated with sulfur after intravenous tumor cell injection achieved a marked reduction of pulmonary colonization in mice. Treatment of the mice with extracts of young radish cultivated with sulfur did not show any increase in the number of CD8+ or NK T cells in the spleen, indicating no influence on host immunity. Sulforaphane, which could be a candidate for an active compound from young radishes cultivated with sulfur, inhibited cell growth of B16-F10 melanoma cells. In addition, extracts of the young radish cultivated with sulfur-fed group showed enhanced quinine reductase (QR) activities in the liver and lung and a slight increase of glutathione S-transferase (GST) activity in the liver. These results suggested that the administration of extracts of young radishes cultivated with sulfur suppressed pulmonary tumorigenesis, possibly due to increased activity of detoxification enzymes in the liver and lung, and partly due to cell cytotoxicity.

  • Considering that interkorean relations got worse and worse recently, cyber terror of North Korea has seriously become a possibility. Therefore, DoS(Denial of Service), a typical way of cyber terror, is becoming a big issue. Consequently, people are growing more and more interested in information security. Internal DoS attacks, out of a variety of ways of Dos attacks, include disks and memories and shortages of process resources. PAM(Pluggable Authentication Module) is one of the ways of preventing internal DoS attacks in Linux system. This paper provides with a method to internally respond to dos attacks and efficiently prevent shortages of resources by utilizing PAM.
