Food is a common source of chromium (Cr) exposure. However, it is difficult to analyze Cr in complex food matrices by using inductively coupled plasma mass spectrometry (ICP-MS) because the major isotope, $^{52}Cr$, is masked by interference generated by the sample matrix and the plasma gas. Among the systems available to minimize interference, the recently developed collision-reaction interface (CRI) has a different structure relative to that of other systems (e.g., collision cell technology, octopole reaction system, and dynamic reaction cell) that were designed as a chamber between the skimmer cone and quadrupole. The CRI system introduces collision or reaction gas directly into the plasma region through a modified hole of skimmer cone. We evaluated the use of an CRI ICP-MS system to minimize polyatomic interference of $^{52}Cr$ and $^{53}Cr$ in various foodstuffs. The $^{52}Cr$ concentrations measured in the standard mode were 2-3 times higher than the certified values. This analytical method based on an ICP-MS system equipped with a CRI of helium gas was effective for Cr analysis in complex food matrices.

The purpose of this study was to evaluate the important changes and the trends in Korean newspaper articles related to 1) food habits and food consumption patterns 2) nutrition, health and diseases 3) food safety and policy. The method used in this study was content analysis of the articles pressed in Donga ilbo and Choseun ilbo from January 1960 to June 1996. Among the total 1814 articles, those on nutrition, health and disease were 922 (50.8%), food safety and policy were 490 (27%) and food habits and consumption patterns were 402 (22.2%). The articles related to food habits and consumption patterns dealt with four contents, food habits reformation, changes in food consumption patterns, nutritional status and food habits. The frequencies of food habits content were highest (51.1%) and especially increased in 1980's and 1990's as the concerns on health and pursuit of convenience were increased. Most of contents related to food habits were health and longevity diet (44%) and eating out (27.5%). The percentile of food habits reformation, the changes in food consumption patterns and nutritional status were 20.1%, 18.4% and 10.0%, respectively. The contents of food habits reformation were most interested in 1960's when food shortage and poverty prevailed. Nowadays, the major subjects of food habits reformation were changed to the problem of wastage and the use of our agricultural foods. The frequencies of change in food consumption patterns were gradually increased from 1960's (7 item) to June 1996 (34 items). And the most of contents related to nutritional status were focused on suffering from food shortage especially in 1960's.

본 실험 은 한방에서 특히 산모의 산후 회복에 효과적 이라고 알려진 호박이 산욕기 산모의 혈액성상 회복에 어떤 영향을 주는지 알아보기 위해서 진행되었다. 호박을 주원료로 8가지 한방 생약재를 첨가하여 압출액을 만든 후분만 직후의 산모 50명 에 게 21일간 복용시키고 혈액을 채취하여 적혈구와 hemoglobin을 복용전과 비교하였으며 또 호박 및 한방 생 약재를 복용하지 않은 대조군과도 비교 하였다. 본 실험 의 결과 적혈구 수치 는 분만직후의 3.65 $\times$$10^{6}$/mm에 서 4.6$\times$$10^{6}$/mm로 증가하여 3.9$\times$$10^{6}$/mm인 대조구에 비하여 높은 증가효과를 보여주었으며 정상적인 적혈구 범 위 에 드는 결과를 보여주었다. Hemoglobin의 경우도 분만 직후 10.35 g/dL에서 복용 21일 만에 12.61 g/dL로 증가하여 대조군인 10.88 g/dL과 비교하였을 때 유의적인 증가효과를 보여주었다 Hemoglobin수치 역시 임신 초기의 평균적인 수준을 초과하였으며 정상의 범위에 속하는 수준으로 회복하는 결과였다. 이후 적혈구와 hemeglobin 뿐 아니라 좀더 자세한 혈액성상을 연구할 과제가 있으나 본 연구의 결과 호박을 주원료로 한 한방 생약재 추출액은 분만 직후 산모의 적혈구 수치 및 hemoglobin의 회복에 효과적이라고 생각된다.

Though food safety efforts of the government has been increasing, but the health hazards resulting from food does not stop and thus increases consumers' anxiety and distrust of government. For more reliable safety management, developing analysis and intake measurement methods and strengthening regulatory control with strict criteria is necessary. In addition, as not only the known hazards by now, but also unknown but obvious hazards are simultaneously ongoing in current environments, the unified risk management and health assessment for food, health food and medicines from the media is critical. As risks and damage to health may show up after a long time after exposure, preventive measures and strategies for safety control is also needed.
