윤종국,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.3

In the biological world, there are a number of ecological fights for survival between each organism such as plants, animals and microorganism. In such events, an organism can use its natural bioactive products as defence agent against other organism. Furthermore, natural bioactive products can be utilized for medicine or functional food. Recently, we investigate the effect of Monascus pigment extracted from a fungus, Monascus anke, on the alcohol metabolism and blood lipid profile. In the present study, it is observed that Monascus pigment supplemented dietary may have a hepatoprotective effect on rat's liver damage induced with CCl₄. By treatment with CCl₄(3 times, I.P), liver damage was reduced more in the rats fed 2% Monascus pigment extract supplemented diet than those fed standard diet, based on the serum levels of alanine aminotransferase, microsomal glucose-6-phosphatse activity and hepaic malondialdehyde content. On the other hand, oxygen free radical generating enzymes, hepatic P-450 dependent aniline hydroxylase, xanthine oxidase, and oxygen free radical scavenging enzymes, hepatic glutathione S-transferase, catalase, superoxide dismutase activities were generally higher both in CCl₄, treated group and control fed 2% Monascus pigment extract supplemented diet than those fed standard diet. In conclusion, the rats fed 2% Monascus pigment extract supplemented diet showed more reduced liver damage than those fed standard diet, which may be due to the acceleration of oxygen free radical metabolism.

To make clinical research ethical, the ethical committee, Institutional Review Board(IRB) is needed and is being controlled by the governmental regulations, Good Clinical Practice(GCP). This short review introduces some of the important concepts in ethics in clinical trial, especially in IRB. In IRB review, 7 necessary requirements should be considered : (1) value : enhancements of health or knowledge must be derived from the research; (2) scientific validity the research must be methodologically rigorous; (3) fair subject selection : scientific objectives, not vulnerability or privilege. and the potential for and distribution of risks and benefits, should determine communities selected as study sites and the inclusion criteria for individual subjects; (4) favorable risk-benefit ratio : within the context of standard clinical trial and research protocol, risks must be minimized, potential benefits enhanced. and the potential benefits to individuals and knowledge gained for society must outweigh the risks, (5) independent review : unaffiliated individuals must review the research and approve, amend, or terminate it, (6) informed consent : individuals should be informed about the research and provide their voluntary consent, and (7) respect for enrolled subjects : subjects should have their privacy protected, the opportunity to withdraw, and their well-being monitored. To review protocols of clinical research, IRB members should have not only the scientific and statistical knowledge, but also ethical and legal knowledge.

The expression frequency of BrdU-induced fragile sites was examined in stomach cancer patients to determine whether this parameter could be used as a marker of genetic susceptibility in at-risk individuals. G banding performed to detect fragile sites. No difference was found in expression frequency between the stomach cancer patients and a group of normal individuals(p=0.7). This indicates that the expression frequency of BrdU-induced fragile sites is not a suitable marker for assessing genetic susceptibility in stomach cancer patient.
