Korea is striving to establish a research ethics system, but there is still a disagreement as to the level of government involvement in research ethics. Therefore, this study analyzed the formation process of research ethics system in the United States and sought to derive implications for Korea's research ethics policy. The analysis of the present status of the research ethics policy and laws of the United States showed that i) the establishment of regulatory system is done only after the principles of the research ethics or the guideline are presented first in the academic fields; ii) the responsibility for research ethics is to be shared by the federal government and the research institute, and the primary responsibility for research is given to the research institute and the secondary responsibility to the government; iii) the government has imposed a minimum extent of strong regulation on unethical research; and iv) it is necessary to extend the responsibility of unethical research from the individual level to the structural level.

The use of animals heavily impacts the mental health of researchers performing the animal experiments. The animal researchers need to take care of animals but also give pain and sacrifice them at the same time. This circumstance can cause a variety of mental stress to the researchers. The stress generated in the laboratory would not only negatively affect the management of animals and the research results, but also would harm the researchers' physical and mental health. Because the feeling of sympathy for animals is a natural feature of humanity, psychological stress following a laboratory animal's death after use is not surprising. It is necessary to revise the relevant laws based on understanding the difficulties of animal researchers in society and to develop related educational programs at the national level to help the psychology and emotions of researchers who conduct animal experiments.

Combustion Toxic Effects among several factors of risk encountered during fire are important in the evacuation and final survival, and they are broader and fatal than the direct damages caused by flame. Most studies on fire toxicity until the present are limited to fatality, mainly deaths by fire through pathological research. In this study, it is conducted as a fundamental experiment to address 3 principles of animal experiment and to provide an alternative test to animal testing that is regulated by national building codes and it was conducted through approval by the animal testing ethics committee. Hence, in this study average time of activity stop was measured after directly inhaling toxic gases (HCN) to laboratory animals (mice) through gas toxicity test (KS F 2271) for major asphyxiating gases(HCN) which are produced during fire combustion. effects of Combustion toxic gases on body were quantitatively analyzed through changes in internal organs and hematological analysis, and electrophoresis of a single cell of these laboratory animals. Biological conclusion of combustion toxicology is drawn through approaches (pathological examination, blood test, blood biochemical test, electrophoresis analysis of single cell) which could not confirmed in existing gas toxicity test.

Objectives : This study was conducted to analyze the single dose toxicity of Mecasin (Gami-Jakyak Gamcho buja Decoction) herbal acupuncture administered in the vein of Sprague-Dawley rats. Methods : All experiments were performed at the Medvill, an institution licensed to conduct nonclinical studies, under the Good Laboratory Practice (GLP) regulations. Sprague-Dawley rats were chosen in this pilot study. In the experiment, Sprague-Dawley rats were divided into four groups of five male and five female animals per group. Doses of Mecasin herbal acupuncture, at 0, 500, 1,000, and 2,000 mg/kg, were given to the experimental groups, and a dose of normal saline solution, at 2 ml/kg, was administered to the control group. Mecasin herb acupuncture and normal saline were injected into the vein at once, and we observed mortality, clinical signs, weights, and gross findings for 14 days after injection. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results : There is no death or abnormality in any of the four groups. All groups put on weights favorably. There are no significant gross findings in necropsy examinations. Conclusions : The above results showed that intravenous injection of 500-2,000 mg/kg of Mecasin herb acupuncture did not cause any changes in weight or, in the results of necropsy examinations, in mortalities. Therefore, the toxicity of Mecasin herb acupuncture was not confirmed, and the presumptive lethal dose of Mecasin herb acupuncture was higher than 2,000 mg/kg. The outcomes suggest that treatment with Mecasin herbal acupuncture is relatively safe. Further evaluations on this subject are needed to yield more concrete evidence.
