  • The radiation has been utilized in a number of fields, even though the use of plenty cause a variety of side effects. This study was confirmed for radiation protective effects of aged garlic to contribute to the prevention of disasters that are radiation exposure. We studied the Complete Blood cell Count(CBC) and the small intestine after feeding aged garlic extract into Sprague Dawley Rat which irradiated X-ray beam 7 and 13 Gy. Garlic extract was administered to the results in the experimental group showed a notable difference in the CBC of platelets (p<0.05), red blood cells (p<0.05) and early damaged white blood cells (p<0.05). In addition, it was confirmed that experimental group's small intestine crypt is more survival than irradiation group significantly. And experimental group has small intestine villi length almost similar to the normal group. result of the aged garlic study will be able to be of great benefit for the radiation relevant emergency management.

  • The main idea of this paper is to present the general attributes of the current IAEA programs and their prospects in the arena of occupational radiation protection, thus responding to a need to attain a consolidated understanding of the Agency's programs for an effective and efficient deployment of the respective national R&D projects in Korea. In addition, the considerable and beneficial benefits from a participation in the IAEA programs have been analyzed and their immediate relevance has been emphasized. A strategy for the enhancement of an active participation in the program and its efficient implementation has also been established. It is expected that the suggested recommendations such as the long term strategy and the relevant guidelines will be helpful in establishing a nuclear policy for the further development of the international cooperative projects in the future.

Drug Toxicities of S-2-(W-aminoalkylamino) ethyl and S-2, W-diaminoalkyl Isothiuronium Bromides and their Potent Radioprotective Effects (S-2, - (W-aminoalkylamino) ethyl 및 S-2, W-diaminoalkyl Isothiuronium Bromide 의 약독성(藥毒性)과 방사선장해방호(放射線障害防護) 효과)

  • S-2, W-diaminopentyl isothiuronium bromide and relevant thiophosphate derivative were prepared starting from both phthalimide and l-ornithinic acid. Drug toxicities of the prepared isothiuronium bromide and S-2-(W-aminoalkylamino) ethyl isothiuronium bromides were tested through ICR male mice, 4 and 8 weeks old and weighing $25{\sim}35g$. The former compound was found to be less toxic than those of latter compounds. This difference of drug toxicities seemed to be originated from their chemical structures, which were examined through IR Spectrometry Radioprotective effects of these compounds were discussed through relevant research data and diaminopentyl derivatives are considered to be a potent radioprotectant with low drug toxicity.
